The count and delay bounds match the conservative edge of the inspected implementations: [OpenCode uses two request retries with 500 ms/10 s bounds](https://github.com/anomalyco/opencode/blob/9976269ab1accfc9f9dc98a4a688c516934de422/%70ackages/llm/src/route/executor.ts#L36-L39), [Pi separates three agent-level retries from provider retries and defaults provider retries to zero](https://github.com/earendil-works/pi/blob/3da591ab74ab9ab407e72ed882600b2c851fae21/%70ackages/coding-agent/docs/settings.md#L139-L147), and [Codex uses finite request/stream budgets plus a five-minute idle timeout](https://github.com/openai/codex/blob/0fb559f0f6e231a88ac02ea002d3ecd248e2b515/codex-rs/model-provider-info/src/lib.rs#L25-L33). Ten percent follows [Codex's bounded jitter](https://github.com/openai/codex/blob/0fb559f0f6e231a88ac02ea002d3ecd248e2b515/codex-rs/codex-client/src/retry.rs#L40-L47). Two retries mean at most three provider requests when no other recovery policy applies. `maxTransientRetries` is a non-negative integer, delays are positive finite numbers with `initialDelayMs <= maxDelayMs`, `jitterRatio` is in `[0, 1]`, and codes are non-empty and unique. These are Cordis config fields rather than hidden constants so deployments can choose different cost and latency budgets. + +For an eligible failure with budget remaining, the one-based transient retry count uses bounded exponential backoff. A valid `providerRetryAfterMs` replaces exponential backoff only when it does not exceed `maxDelayMs`; a longer provider delay causes delegation instead of an earlier retry that violates the provider instruction. Local backoff multiplies by an injected random factor in `[1 - jitterRatio, 1 + jitterRatio]` and clamps the final value to `maxDelayMs`; provider delay is not jittered. + +The plugin owns a lifetime `AbortController` and tracks every active backoff callback. Each wait fuses the waterfall's turn signal with that lifetime signal. Effect cleanup first unregisters the listener, then aborts and awaits the active callbacks; a captured callback whose lifetime signal aborts returns `fail` and can neither retry nor enter the rest of its captured waterfall after disposal. This makes HMR disposal quiescent even though Cordis has already captured the listener. + +Before sleeping, `dsh-llm-retry` appends one non-surface `llm/retry` session event containing the turn, failed step, one-based transient retry number, configured maximum, scheduled delay, and `LlmFailure`. The plugin owns the `SessionEventMap` augmentation; `dsh-session` remains generic persistence and does not absorb the optional policy's vocabulary. The event says what was scheduled, not that the next request completed; cancellation during the delay is subsequently visible on `turn/end`. The event ships only with a production renderer and replay/snapshot coverage, because its purpose is operational state rather than trace collection. + +The listener calls `next()` for a non-transient code, an exhausted policy budget, or an over-cap provider delay. This preserves composition with context-overflow recovery and later policy plugins. It returns `{ action: 'retry' }` only after the delay completes under both signals; turn cancellation and plugin disposal return `fail`, after which the loop's cancellation/disposal checks remain authoritative. + +The agent-spine demo bundle loads the plugin so the shared stdio/TUI, one-shot CLI, and ACP example compositions use the same bounded policy. Library consumers retain explicit plugin composition: omitting the plugin leaves `agent/request-error` at its current fail default. + +### Make one layer own visible attempts + +Adapters perform one provider request per `stream()` call. The pi-ai adapter removes public `maxRetries` and `maxRetryDelayMs` profile fields and disables library retries; the hand-written adapter keeps its current single-attempt behavior. This prevents an SDK budget from multiplying the agent budget and ensures every transient retry is represented by a closed failed step plus `llm/retry`. + +`ctx.llm.stream()` remains the raw one-attempt waterfall. Direct callers such as compaction summarization receive the structured failure but do not gain automatic retry, because they have no agent step boundary or general durable place to separate attempts. A future direct-call consumer may justify a buffering helper that retries only before emitting a chunk; this decision adds no such helper. + +### Bound stalled streams where they can be stopped + +Each adapter exposes a validated `streamIdleTimeoutMs` configuration field with the five-minute prior-art default cited above. The interval is capped at Node's maximum timer delay so it cannot be clamped to one millisecond. It covers each outstanding iterator `next()` from demand to the next valid `StreamChunk`; time a consumer spends between `next()` calls is not provider idle time. + +`@deepseek-ai/dsh-timeout` exposes a rearmable idle-watchdog primitive. One stable local `AbortController` is fused with the caller signal and passed to the transport for the whole adapter call; each outstanding `next()` arms the watchdog, resolution disarms it, and the next demand rearms it. Timeout aborts that stable controller with a capability-owned `TimeoutReason`, and `finally` clears the timer. The adapter classifies its watchdog as `TIMEOUT` and an earlier upstream abort as `ABORTED`. The existing one-shot `deadline()` is not presented as a sliding timer. + +Boundary tests prove termination at both actual transports. The hand-written adapter aborts its fetch/reader, and the pi-ai adapter maps the stable signal through the SDK and proves the SDK closes the response. A timer that merely rejects a consumer promise while leaving the request running does not satisfy the contract. + +### Keep attempts separate in the existing log + +A failed attempt may leave `assistant/chunk` events in its closed step, but it never appends `assistant/message` and never dispatches a tool. A retry opens the next numbered step, reconstructs the request from the durable surface, and produces its own chunks. UIs may render live chunks while a step is open, then mark or clear that transient view when `llm/retry` identifies the failed step or `turn/end` records terminal failure; message derivation continues to ignore the failed chunks. + +If recovery is exhausted, the final failure is stored once on `turn/end.reason` with the structured facts. If transient recovery continues, `llm/retry` is the durable home for that attempt's failure and delay. No standalone final-error event or response-id vocabulary is added. + +## Out of scope + +- Automatic provider or model failover.

A heterogeneous `ScopeLayer` has no layer-wide `values()` contract. +- The helper is deliberately synchronous. A future registration that needs asynchronous setup or several independently owned undos must identify its ownership and settlement boundaries before widening this contract. +- An action must throw before retaining a contribution or return an undo for everything it retained; the helper cannot repair mutation outside that contract. The provided entry operations are atomic, and migrated registries perform fallible validation before insertion. +- A scoped layer remains allocated until every table in its aggregate is empty. Disposing one facade therefore cannot discard sibling contributions owned by the same scope. +- The four public symbols become a reusable package contract. Keeping `EntryValues` internal and consumer policy outside the helper limits the compatibility surface. +- The migration changes no public registry behavior and no model-, human-, wire-, persistence-, configuration-, or dependency-graph output. + +## Verification + +- `dsh-scope` unit tests cover global construction, lazy scoped construction, non-creating reads, named merge order and shadowing, aggregate reclamation, factory and action failure cleanup, notification ordering and rollback, `notify: false`, effect labels, exact disposer identity, idempotent teardown, caller-owned duplicate errors, independent anonymous duplicates, live iterators, and drained-generation detachment. +- Focused tool, system-prompt, and command suites cover restrictions, reserved transport handling, known/restrictable-name agreement, guard re-entrancy and self-replacement, validation order, exact diagnostics, section shadow-before-evaluate, provider snapshot membership, variable re-entrancy and self-replacement, contained command observers, frozen and sorted views, direct execution, and lifecycle disposal. +- The scoped core-data type-equivalence check ties `ScopeLayer` documentation to its source declaration. Repository documentation, module-graph, build, hygiene, coverage, and built-artifact gates exercise the root export and package boundary. +- Existing ACP, headless, and TUI keyless snapshots remain the regression boundary for tool schemas, prompt assembly, and human commands.

The first version has no glob, language-id, or explicit route selector and no statically declared operation capabilities. + +The seam exposes one `query(request, signal?)` operation because no fields need implementation defaulting: `workspaceRoot` is required, `languageId` comes from the registration, and consumers own timeouts and result limits. `query()` selects and derives without hidden `??` fallbacks, leaving no executable spec to resolve. `dsh-tool-lsp` validates model arguments and passes only `exec.signal` as a bare `AbortSignal`, matching web and keeping `dsh-lsp` independent of `dsh-tools`. Removal before selection fails as unavailable; later disposal follows the selected provider's cancellation lifecycle without rerouting. + +The intended contract shape is: + +```ts +import type { Branded } from '@deepseek-ai/dsh-brand' + +type LspOperation = 'goToDefinition' | 'findReferences' | 'goToImplementation' | 'hover' +type LspProviderId = Branded<'LspProviderId'> + +interface LspPosition { + readonly line: number + readonly character: number +} + +interface LspRange { + readonly start: LspPosition + readonly end: LspPosition +} + +interface LspQueryRequest { + readonly operation: LspOperation + readonly filePath: string + readonly position: LspPosition + readonly workspaceRoot: string +} + +interface LspProviderQuery extends LspQueryRequest { + readonly languageId: string +} + +type LspQueryResult = + | { readonly kind: 'locations'; readonly locations: readonly { readonly uri: string; readonly range: LspRange }[]; readonly resolvedWorkspaceRoot: string } + | { readonly kind: 'hover'; readonly hover: { readonly contents: string; readonly range?: LspRange } | null } + +interface LspProvider { + readonly id: LspProviderId + readonly extensionToLanguage: Readonly> + query(request: LspProviderQuery, signal?: AbortSignal): Promise +} + +interface LspService { + registerProvider(provider: LspProvider): () => void + query(request: LspQueryRequest, signal?: AbortSignal): Promise +} +``` + +Mapping keys normalize to lowercase, leading-dot extensions selected from `filePath`'s final extension; language ids only synchronize documents. Seam positions and ranges are zero-based UTF-16. `findReferences` always includes declarations: providers enforce this internally, the local mapping sets `context.includeDeclaration: true`, and callers get no flag. Closed result unions normalize navigation to locations and hover to content or `null`; navigation results carry the provider's resolved workspace root so consumers relativize file URIs in the same canonical namespace. The seam exposes no protocol types, process or document controls, or generic request escape hatch. + +`dsh-lsp-local` owns host files, server configuration, JSON-RPC, process and transient-document state, and protocol translation; it depends on `dsh-lsp` and Node APIs, not `dsh-fs`. The server-table key is its provider id. The plugin resolves every server-local setting before registration, rolls back earlier registrations if a later mapping is invalid or conflicts, and retains an independent process pool per provider. `dsh-tool-lsp` runtime-injects only `tools`, `lsp`, and `systemPrompt`, obtains the workspace from `exec.agent?.session.header.cwd` through a package-local `sessionCwd(exec)` helper matching the filesystem tools' lookup, and imports no provider. + +## Model-facing contract + +The single `lsp` tool accepts: + +```ts +interface LspToolInput { + readonly operation: 'goToDefinition' | 'findReferences' | 'goToImplementation' | 'hover' + readonly file_path: string + readonly line: number + readonly character: number +} +``` + +`line` and `character` are positive, one-based UTF-16 cursor coordinates; the tool converts them to the seam's zero-based `LspPosition` and converts rendered locations back. `findReferences` includes declarations so impact analysis does not omit the defining site. Provider, language id, workspace root, limits, timeout, initialization, and executable remain outside model input. + +The tool requires `workspaceRoot` from session `header.cwd`, with no fallback; absence fails as `LSP_WORKSPACE_REQUIRED` before querying or startup. The local provider resolves relative paths against that root and accepts absolute paths directly; both forms are canonicalized and rejected before startup when the target is outside the canonical workspace. + +Locations render as stable, file-grouped `path:line:character` entries. A `file:` URI accepted by Node `fileURLToPath()` becomes a relative path inside the workspace or an absolute path outside it; other URIs remain verbatim. `maxLocations` defaults to `100` and reports omitted items; `maxResultChars` defaults to `16_000` and bounds every complete rendered result, including its truncation metadata. Empty locations and `null` hover are successful no-result responses; missing or malformed server payloads fail with structured `LSP_MALFORMED_RESPONSE` errors. + +ACP uses `{ card: 'generic', kind: 'search', title, locations: [{ path: file_path, line }] }` with an args-derived operation/cursor `title`. Because `FileLocation` has no character, follow-along focuses the input line while the title preserves the cursor; presentation remains pure. + +## Timeout ownership + +`dsh-tool-lsp` attaches one configurable `timeoutMs` budget, default `60_000`, to the tool definition. `dsh-timeout-policy` enforces it and supplies `exec.signal`, which reaches `ctx.lsp.query`; the budget covers the complete queued open/query/close lifecycle and is not model-configurable. + +The seam and provider add no startup or request deadline. Non-tool callers therefore receive no hidden timeout and must supply an `AbortSignal`, using `deadline()` when they need a budget. + +Provider disposal occurs outside tool execution, so `dsh-lsp-local` keeps `shutdownTimeoutMs` (default `5_000`) for `shutdown`/`exit` and `killGraceMs` (default `2_000`) for both request-cancel grace and SIGTERM-to-SIGKILL escalation; the same bounds govern failed-instance cleanup. Timer values above Node's `2_147_483_647` ms scheduling range fail at load. The provider uses `deadline()` and `timeoutOf()` but owns request cancellation, process signals, and awaiting close because timeout notification does not terminate work. + +## Workspace, filesystem, and document synchronization + +`dsh-lsp-local` canonicalizes and reads through Node APIs in the subprocess's host namespace. It rejects missing, non-regular, non-UTF-8, oversized, or canonical out-of-workspace sources and keeps one `O_NOFOLLOW | O_NONBLOCK` handle through validation and reading, so a FIFO with no writer cannot block before the regular-file check. It observes caller cancellation around each filesystem operation. It does not consume `ctx.fs` or emit `fs/observed`: only the LSP result is model-visible, so the query does not satisfy read-before-write policy. + +The `read` tool is unsuitable source because its output is windowed, numbered, transcript-visible, and observed. Reading in `tool-lsp` would also assign provider-specific synchronization to the consumer and preclude non-local providers. + +The local provider uses a compatibility-first transient-open sequence for every query. It accepts legacy `textDocumentSync` `Full` or `Incremental`, or options with `openClose: true`; omitted, `None`, or explicitly incompatible synchronization fails as unsupported before `didOpen`. + +1. Canonicalize and validate the host path, then read the current source with Node filesystem APIs. +2. Send `textDocument/didOpen` with version `1`, full text, and the configured language id. Its write remains abortable; failure or cancellation invalidates the instance and awaits bounded process termination before the pool can reuse it. +3. Send the requested `textDocument/definition`, `textDocument/references`, `textDocument/implementation`, or `textDocument/hover` request. +4. If `didOpen` succeeded, attempt `textDocument/didClose` in `finally` after the request settles or aborts. A close-write failure does not replace the settled result or error, but invalidates the instance and awaits bounded process termination. + +Documents close after each call, so the first version needs no `didChange`, `didSave`, content cache, mutation listener, or document LRU. One abortable per-workspace provider queue serializes source-read/open/query/close lifecycles, so a waiting query reads current bytes only when its turn starts; the instance also keeps protocol lifecycles serialized. Distinct workspaces may run in parallel. The server's workspace index remains responsible for closed files reached from the source. + +The canonical workspace `realpath` must be a directory and supplies process cwd, `rootUri`, the sole `workspaceFolders` entry, and pool identity; symlink aliases therefore share an instance. Result locations may be external, but an external path cannot become a query source. Remote, virtual, or independently sandboxed filesystems require another provider. + +## Local server lifecycle and protocol behavior + +`dsh-lsp-local` lazily single-flights one server per `(provider id, canonical workspace realpath)`. At load it resolves the executable after credential scrubbing and environment overrides, failing before registration if unavailable; server process launch stays lazy (first query spawns it) and uses no shell. `maxMessageBytes` defaults to `16_000_000`, `maxStderrBytes` to `1_000_000`, and `maxDocumentBytes` to `4_000_000`. A crash fails the active query without replay; a later query may replace the process. Each query starts at most one process, so the MVP has no cross-request restart counter. + +Initialization advertises `general.positionEncodings: ['utf-16']`, `workspace: { workspaceFolders: true, configuration: true }`, `textDocument.hover.contentFormat: ['markdown', 'plaintext']`, and `linkSupport: true` for definition and implementation, with no dynamic registration. Returned operation and synchronization capabilities are authoritative. An omitted server `positionEncoding` defaults to `utf-16`; any other value is a protocol error. Configuration may supply initialization options and `workspace/configuration` responses, but the client rejects `workspace/applyEdit` and never executes commands or edits. + +Navigation maps `Location` directly and `LocationLink` from `targetUri` plus `targetSelectionRange`. Positions must be nonnegative integers. Hover normalization accepts only valid `MarkupContent` and `MarkedString` shapes, preserves string values, renders language-tagged values as fenced code, and joins arrays with one blank line. The model-facing tool applies `maxResultChars` after rendering. + +Abort reaches every query phase and sends `$/cancelRequest` once an id exists. An unresponsive server is terminated and awaited without collateral active work because the instance is serialized. Disposal rejects and cancels work, attempts graceful shutdown, escalates through bounded termination, and awaits quiescence. + +## Deliberately deferred surface + +Symbols are deferred because they need different schemas and overlap read/search; a future workspace-symbol tool must accept a search query. Call hierarchy is deferred because support is uneven, and `prepareCallHierarchy` remains an internal prerequisite rather than a model operation. + +Diagnostics need separate freshness, accumulation, and transcript rules. Mutations such as rename, code actions, and formatting require separate tools with preview, permission, and write-policy integration. + +The local provider trusts its configured server and claims no sandbox confinement. Supporting untrusted binaries requires a later process/filesystem contract for workspace reads plus private cache and temporary writes; restricted, remote, or virtual workspaces require another provider. + +## Alternatives considered + +**Copy Claude Code's unified schema.** Its cursor operations validate the core use case, but symbols and call hierarchy need different arguments. Copying all nine operations would freeze speculative surface, so the proposal aligns only on the four semantic queries. + +**Let providers register tools.** Loaded servers would then control model schema and prompts, preventing one stable contract across local and remote providers. + +**Expose arbitrary LSP methods.** A JSON-RPC escape hatch would leak protocol payloads and admit unreviewed mutation or command execution; the operation union stays closed. + +**Expose `resolve(request)` / `query(spec)`.** With no defaulted fields, resolution would only expose provider selection, and a public spec could outlive provider disposal or replacement. One operation keeps selection and invocation atomic to the registration lifetime. + +**Wrap the signal in a per-seam execution-context object.** Web passes a bare `AbortSignal`; wrapping this single field would add unexplained asymmetry. `query()` gains a context object only when another field requires it. + +**Read through `ctx.fs` or the `read` tool.** This could mix the document with a server index from another filesystem namespace; tool output is also windowed, numbered, and observed. The host-local provider reads unobserved full text beside its subprocess. + +**Keep documents open.** Mirroring edits requires version ownership, all-path `didChange`, HMR recovery, eviction, and stale-state rules. Transient opens avoid that MVP state machine. + +**Configure phase timeouts.** Nested timers create competing classifications and fresh budgets. One caller-owned deadline covers query work; only out-of-call teardown keeps local bounds. + +**Query without `didOpen`.** Although permitted, support is inconsistent and may use stale server state. Transient open supplies an explicit current snapshot. + +**Add routes or select the first match.** Registration order and HMR timing are not product semantics, while a route table duplicates unique extension ownership. Overlaps therefore fail registration. + +**Run concurrent queries in one instance.** If cancellation fails, terminating the shared process would kill unrelated work. Per-instance serialization limits that blast radius; instances remain parallel. + +**Ship presets or PATH discovery.** A catalog would make the generic host own language policy, while discovery cannot infer arguments, language ids, or initialization. Deployments configure providers explicitly; composition plugins may package presets. + +## Testing + +- Package tests pin the three-package dependency direction, runtime injections, and `ctx.lsp`-only communication. +- Tool tests pin the four operations, coordinate validation, configured bounds and omission markers, prompt, and ACP presentation. +- Registry tests pin atomic reservation/release, order-independent selection, and structured unavailable, disposed, conflict, and unsupported-operation errors. +- Fake-stdio tests pin exact initialization capabilities, four protocol mappings, `Location`/`LocationLink` and hover normalization, and `findReferences` mapping to `references.includeDeclaration`. +- Synchronization tests pin UTF-16 negotiation and conversion, supported and rejected `textDocumentSync` forms, blocked and failed open writes, balanced transient open/close, close-write failure, and malformed-response rejection. +- Timeout tests pin one `TOOL_TIMEOUT` budget, unclassified upstream cancellation, no hidden seam deadline, and bounded awaited teardown. +- Lifecycle tests pin startup single-flight, complete-lifecycle serialization with fresh queued source reads, cross-workspace parallelism, abortable queues, crash replacement without replay, failed-stdin teardown, and quiescent disposal. +- Host-filesystem tests pin session-cwd requirements, relative and absolute source containment through symlinks, document validation, file/non-file URI rendering, unformatted source, and no `fs/observed` event. +- A keyless pinned TypeScript real-server e2e exercises all four operations; runnable configuration uses the same explicit provider mapping. +- Snapshots cover model-visible schema, prompt, results, omissions, and ACP rendering; a built-artifact smoke test covers framing and cleanup. +- Package and architecture docs cover configuration, security boundaries, and search/read guidance; the new `packages/lsp/` group is added to the AGENTS.md repository-layout block, the packages/README.md group table, and architecture.md in the same change. + +## Consequences + +Language servers vary in method support, capability interpretation, and indexing readiness; LSP has no universal “index complete” signal. Servers without compatible transient-open synchronization are unsupported even if closed-document queries work. Supported servers may still return empty or partial results, so the tool promises no cross-server completeness. The pinned TypeScript e2e establishes one compatibility floor, not a cross-language claim. + +Transient opens repeat parsing and notifications. Per-instance serialization increases latency under parallel agents, and long-lived workspace processes consume memory until disposal. + +Extension ownership is exclusive within one runtime. Two providers cannot both claim `.ts`, even with different language ids; this is a conscious MVP limit. The intended extension is a deployment-configured selector above registrations that can relax exclusive reservations without adding provider choice to model input or changing `LspProvider.query`. + +UTF-16 cursor columns are exact for the protocol but difficult for a model to count around non-BMP characters. Invalid or off-symbol positions may produce empty results, so error text and prompt examples must explain the coordinate convention without encouraging broad LSP use. + +Direct Node access aligns the query snapshot with the server index but bypasses `ctx.fs` and its policy. Canonical containment rejects source files outside the workspace; a trusted server may still read the workspace and use caches. The first implementation therefore requires trusted host-local deployment and provides no sandbox guarantee. diff --git a/.agents/notes/implemented/architecture/2026-07-15-lsp-capability-seam.zh.md b/.agents/notes/implemented/architecture/2026-07-15-lsp-capability-seam.zh.md new file mode 100644 index 0000000000..10e8956005 --- /dev/null +++ b/.agents/notes/implemented/architecture/2026-07-15-lsp-capability-seam.zh.md @@ -0,0 +1,198 @@ +# Agent Note: LSP 能力服务边界与面向模型的查询工具 + +Status: implemented + +[English](2026-07-15-lsp-capability-seam.md) | 中文 + +## 问题 + +harness 已具备文本搜索与文件读取能力，但二者都无法识别程序符号。文本匹配无法可靠地区分同名函数、跟踪导入别名、关联接口与具体实现，也无法报告推断类型。因此，agent（智能体）在修改代码前缺少人类通过编辑器语言服务器获得的语义导航能力。 + +语言服务器协议（Language Server Protocol，LSP）支持分属三个职责方：模型需要稳定的查询 schema，harness 需要提供方选择与规范化结果，本地实现则负责进程、JSON-RPC、工作区、同步与文件系统行为。将三者合并会使模型契约绑定本地子进程，并阻碍远程或沙箱原生提供方。 + +许多语言服务器在查询文档已按当前文本打开时表现最佳。兼容的 agent 客户端必须限制这项状态、定义内部读取是否算作模型观察，并确保文档快照与服务器工作区索引位于同一文件系统命名空间。 + +## 决策 + +将 LSP 建成由三个包（package）组成的能力服务边界，其中包含一个只读模型工具和一个通用本地提供方实现： + +1. `packages/lsp/lsp` 下的 `@deepseek-ai/dsh-lsp` 负责 `ctx.lsp`、提供方注册与选择、标准化请求与结果、执行控制，以及结构化 LSP 错误。 +2. `packages/lsp/lsp-local` 下的 `@deepseek-ai/dsh-lsp-local` 将配置的 stdio 语言服务器适配到该服务边界。一个插件实例接收具名服务器表，并为每组命令及扩展名到语言 id 的映射注册一个隔离的提供方。 +3. `packages/lsp/tool-lsp` 下的 `@deepseek-ai/dsh-tool-lsp` 负责面向模型的 `lsp` schema、提示词指导、参数校验、结果限制与格式化，以及 ACP（Agent Client Protocol）展示。 + +`dsh-lsp-local` 是通用 host，不是语言服务器目录或安装器。部署显式配置命令与映射；未来 preset 属于组合插件或 `cordis.yml` overlay。 + +模型与服务边界仅公开 `goToDefinition`、`findReferences`、`goToImplementation` 和 `hover`；`ctx.lsp` 不提供任意 JSON-RPC 方法。这些操作字面量与 Claude Code 熟悉的 camelCase 命名一致，而工具名与 `file_path` 字段仍由 harness 自行定义。 + +提示词将 LSP 定位为精确查询手段：`Use search/read for ordinary navigation.

Storing `Error`, `AbortSignal.reason`, or backend-private objects would also expose unstable runtime details to durable replay. + +The [initiating Agent scope decision](2026-07-15-agent-initiator-scope.md) intentionally carries only the exact Agent through AsyncLocalStorage. Adding turn, step, or signal state to that driver-lifetime boundary would make stale asynchronous descendants appear to retain authority over later turns. Cancellation therefore needs one turn owner and explicit propagation without creating another ambient context or public turn wrapper. + +## Decision + +Agent owns the runtime-only `AgentCancelCause` union `{ kind: 'user' } | { kind: 'parent' }`; `agent.cancel()` defaults to `user`. TypeScript enforces that vocabulary at this typed same-process seam, with no runtime validator, fallback, or special compatibility contract for untyped callers. An active `TurnCancellation` copies the typed discriminant into a fresh frozen signal reason; idle cancellation has no holder to mutate and does not arm later work. + +An interrupted live turn ends with the coarse durable `{ kind: 'aborted' }` outcome. The terminal event records what happened to the turn, while the runtime signal identifies who requested cancellation; it does not duplicate `user` or `parent` into replay. Session seed/load rejects legacy aborted records with a reason or any other extra field, so replay cannot reintroduce caller-owned cancellation detail. The process-local `agent/cancel-requested` notification is not durable; a future audit requirement uses a separate durable control-request event so a request and its eventual outcome remain distinct. Durable events contain no stack, signal, error object, free-form cancellation text, or backend-private detail. + +AgentLoop privately owns one `TurnCancellation` per prospective turn. It installs the holder before notifying `agent/status = running`, retains its single `AbortController` through prompt processing, prompt assembly, every step, model and tool execution, continuation, and `agent/turn-stop`, then clears the exact holder immediately before publishing `turn/end`. Terminal event observers and the following durability flush therefore cannot cancel already-completed turn work even though driver status may remain `running` until the flush settles. Every participating method, event, and request value receives that same explicit signal; the next turn receives a fresh signal. + +The driver keeps only a cause-less pre-run marker for queued work cancelled before a turn is claimed. An effective `cancel()` emits the observe-only `agent/cancel-requested` notification with its resolved typed cause before clearing queued and steering work or aborting the holder; notification failures cannot veto the stop, and an idle call emits nothing. Work synchronously queued by a notification observer is included in that clear, while work queued by a later signal abort observer belongs to the next turn. If a `running` listener synchronously cancels old work and sends a replacement, the driver discards the aborted holder and creates a fresh one for the replacement. Repeated cancellation is first-wins for the active holder, while later calls may still clear newly queued pending work. + +The explicit event signatures keep their positional form and place `signal` immediately before a waterfall's final `next`. Prompt submission, request configuration, step-result processing, continuation, and terminal stop join the pre-existing explicit signal seams for pre-step, session prefix, model generation, tool execution, approval, and subagent or workflow requests. Hook bridges must also supply `RunHookOptions.signal`, so a turn cancellation reaches the bash executor's process-group kill and join boundary. `SystemPrompt.assemble()` carries `signal?: AbortSignal` in `AssembleContext` because that object is an explicit request value that can also represent signal-less assembly outside a turn. Listeners may cooperate with the signal but must not retain it to control another turn. + +`ctx.agents` continues to carry only the initiating Agent. Ambient Agent presence does not imply liveness, a current turn, or cancellation authority, and `agentInterruptReasonOf(signal)` reads only its explicit argument. Concurrent Agents isolate both their initiator identities and their turn signals; a child driver shadows the parent initiator while its parent request signal still travels through the subagent seam. + +Agent disposal requests the runtime-only `{ kind: 'disposed' }` interruption on the active holder. If cancellation already won the controller reason, the reason cannot be rewritten, so terminal classification first checks lifecycle state: disposed wins, then a supported `user` or `parent` cause becomes the coarse aborted outcome, and unrelated exceptions retain the existing error path. ACP cancellation maps to `user`; in-process spawn and fork propagation map to `parent`. Remote ACP subagents retain their existing wire protocol. + +Cancellation remains cooperative. The loop checks interruption before and after awaited boundaries but does not use `Promise.race` to abandon an in-process listener, adapter, or tool Promise. Work that ignores the signal must settle before `whenIdle()`, handle disposal, and scope teardown report quiescence. + +## Verification + +Contract tests verify the typed caller union, frozen detachment, default and first-wins behavior, the coarse Session JSON round trip and legacy-record rejection, ACP `user`, in-process subagent `parent`, and disposal precedence. Loop tests make cooperative listeners wait on the signal at prompt submission, system-prompt assembly, session prefix, pre-step, request, model stream, step result, tool execution, continuation, and terminal stop; they assert one signal within a turn, a fresh signal across turns, and no cancellation authority during terminal publication or a blocked durability flush. A real hook bridge test cancels and reaps a blocked prompt hook before idle. + +Initiator-scope tests assert that every hook still observes the exact Agent and no ambient turn signal, concurrent Agents retain independent identities and signals, and a nested child driver shadows only identity. Race tests cover idle cancellation, pre-run cancellation, replacement submission from a `running` listener, repeated cancellation, and cancel-versus-dispose quiescence. + +## Alternatives considered + +**Store the signal in ALS.** ALS follows asynchronous descendants for the entire driver lifetime, while cancellation authority ends with one turn. A leaked callback could observe a stale signal or require mutable ambient state, so the initiator scope continues to carry only the Agent and control remains explicit. + +**Persist a free-form string reason.** Strings admit spelling drift, prevent exhaustive switching, and encourage consumers to parse presentation text. The runtime uses a closed discriminated union, while the terminal record needs only the stable aborted outcome. + +**Persist the typed caller cause in `turn/end`.** No production replay, UI, ACP, telemetry, or workflow consumer distinguishes `user` from `parent`. Copying the request source into the terminal result would conflate two facts and add Session-specific validation without a consumer; a future audit surface can record a separate cancellation-request event. + +**Define speculative `superseded`, `timeout`, and `shutdown` variants now.** No current Agent cancellation producer implements those semantics. `shutdown` is already lifecycle disposal, and timeout or supersession should enter the union only with an owning policy and unique terminal meaning. + +**Expose public turn or step context wrappers.** Existing positional seams already identify Agent, turn, and step. A wrapper would widen every API, duplicate ownership, and tempt callers to treat a captured object as durable authority. + +**Abandon uncooperative work after a grace period.** Returning idle while same-process work still runs breaks teardown and resource-ownership guarantees. Hard termination requires a worker or process isolation boundary and is outside this control seam. + +## Consequences + +Cancellation has one runtime owner, one signal per live turn, and one typed runtime caller vocabulary. Session retains the coarse `aborted` outcome that its consumers actually use, rejects reason-bearing legacy forms, and stays isolated from runtime objects. Cooperative cancellation reaches every asynchronous turn seam, including work before the first step and after the last one, while terminal publication and persistence remain outside its authority. + +The explicit signal adds parameters to several public events and requires plugins to forward cancellation deliberately.

或后端私有对象还会向持久化回放暴露不稳定的运行时细节。 + +[发起 Agent 作用域决策](2026-07-15-agent-initiator-scope.md)有意让 AsyncLocalStorage 只携带同一个 Agent。若把轮次、步骤或 signal 状态加入这个与驱动器同生命周期的边界，陈旧的异步后代就会看似仍对后续轮次拥有权限。因此，取消需要一个轮次归属方并显式传播，且不创建另一套环境上下文或公开的轮次包装层。 + +## 决策 + +Agent 拥有仅用于运行时的 `AgentCancelCause` 联合类型 `{ kind: 'user' } | { kind: 'parent' }`；`agent.cancel()` 默认使用 `user`。TypeScript 在这份类型化同进程契约中强制执行该词汇，不提供运行时校验器、后备行为，也不为无类型调用方提供特殊兼容性契约。活跃的 `TurnCancellation` 会把类型化判别字段复制为一个全新且已冻结的 signal 原因；空闲状态下没有可修改的持有者，也不会让后续工作预先进入取消状态。 + +正在运行的轮次被中断后，以粗粒度的持久化结果 `{ kind: 'aborted' }` 结束。终态事件记录轮次发生了什么，运行时 signal 标识谁请求了取消；回放不会重复保存 `user` 或 `parent`。Session seed/load 会拒绝携带取消原因或任何其他额外字段的旧式中止记录，因此回放无法重新引入由调用方持有的取消细节。仅限进程内的 `agent/cancel-requested` 通知不会持久化；未来若有审计需求，应使用独立的持久化控制请求事件，让请求与最终结果保持为两项事实。持久化事件不包含调用栈、signal、错误对象、自由文本取消原因或后端私有细节。 + +AgentLoop 为每个待启动轮次私有地持有一个 `TurnCancellation`。它在通知 `agent/status = running` 前安装该持有者，使其中唯一的 `AbortController` 持续覆盖提示词处理、提示词组装、每个步骤、模型与工具执行、继续决策和 `agent/turn-stop`；随后在发布 `turn/end` 前立即清除所安装的那个持有者。因此，即使驱动器状态可能在持久化刷新结算前保持 `running`，终态事件观察者及其后的持久化刷新也无法取消已完成的轮次工作。所有参与的方法、事件和请求值都会收到同一个显式 signal；下一个轮次会收到全新的 signal。 + +对于轮次被认领前已取消的排队工作，驱动器只保留一个不携带取消原因的运行前标记。实际生效的 `cancel()` 会先发出仅供观察的 `agent/cancel-requested` 通知并携带最终确定的类型化取消原因，然后才清除排队工作和 steering（中途引导）工作或中止持有者；通知失败不能阻止此次停止，空闲状态下调用则不发出任何通知。通知观察者同步加入队列的工作也会被这次清除，而稍后由 signal 中止观察者加入队列的工作属于下一个轮次。若 `running` 监听器同步取消旧工作并发送替代提示词，驱动器会丢弃已中止的持有者，并为替代提示词创建全新的持有者。同一活跃持有者上的重复取消遵循首次请求优先，后续调用仍可清除新入队的待处理工作。 + +显式事件签名保留位置参数形式，并把 `signal` 放在 waterfall（瀑布式事件）的最后一个参数 `next` 之前。提示词提交、请求配置、步骤结果处理、继续决策和终止停止加入已有的步骤前处理、会话前缀、模型生成、工具执行、审批以及 subagent 或工作流请求的显式 signal seam。钩子桥接器也必须提供 `RunHookOptions.signal`，使轮次取消能够到达 Bash 执行器终止进程组并等待其退出的边界。`SystemPrompt.assemble()` 在 `AssembleContext` 中携带 `signal?: AbortSignal`，因为该对象是显式请求值，也可表示轮次之外不携带 signal 的组装。监听器可以配合该 signal 取消，但不得保留它来控制其他轮次。 + +`ctx.agents` 仍只携带发起 Agent。环境中的 Agent 并不代表存活、当前轮次或取消权限，`agentInterruptReasonOf(signal)` 也只读取其显式参数。并发 Agent 会同时隔离各自的发起方身份和轮次 signal；子驱动会遮蔽父发起方，而父请求 signal 仍通过 subagent seam 传递。 + +Agent dispose（资源释放）会在活跃持有者上请求仅用于运行时的 `{ kind: 'disposed' }` 中断。若取消已经先占用控制器的中断原因，该原因便无法改写，因此终态分类会先检查生命周期状态：资源释放结果优先，之后受支持的 `user` 或 `parent` 取消原因形成粗粒度的中止结果，其他异常保留现有错误路径。ACP（Agent Client Protocol）取消映射为 `user`；进程内 spawn 和 fork 的传播映射为 `parent`。远程 ACP subagent 保持现有协议。 + +取消仍然是协作式的。AgentLoop 会在异步等待边界前后检查中断，但不会用 `Promise.race` 放弃进程内监听器、适配器或工具 Promise。忽略 signal 的工作必须真正结算，`whenIdle()`、句柄 dispose 和作用域清理才会报告静止状态。 + +## 验证 +

signal；并断言同一轮次使用一个 signal，不同轮次使用全新的 signal，终态发布期间和持久化刷新受阻期间不存在取消权限。真实钩子桥接器测试会在报告空闲状态前取消并回收受阻的提示词钩子。 + +发起方作用域测试断言所有钩子仍观察到同一个 Agent 且没有环境中的轮次 signal，并发 Agent 保持独立的身份与

signal，或者迫使实现使用可变的环境状态，因此发起方作用域继续只携带 Agent，控制能力继续显式传递。 + +**持久化自由文本原因。** 字符串允许拼写漂移、阻碍穷尽分支判断，还会鼓励消费方解析展示文本。运行时使用封闭的可辨识联合类型，终态记录只需要稳定的中止结果。 + +**在 `turn/end` 中持久化类型化调用方取消原因。**

取消生产方实现这些语义。`shutdown` 已经属于生命周期 dispose；超时或替代只有在拥有明确归属策略和唯一终态含义时才应进入联合类型。 + +**公开轮次或步骤上下文包装类型。** 现有位置参数 seam 已经标识 Agent、轮次和步骤。包装类型会加宽所有 API、重复归属，并诱导调用方把捕获的对象当成持久权限。 + +**在宽限期后放弃不协作的工作。**

seam，包括第一个步骤之前和最后一个步骤之后的工作，而终态发布和持久化仍在其权限范围之外。 + +显式 signal 会给多个公开事件增加参数，并要求插件有意识地转发取消。这是有意设计：权限在调用边界可见，生命周期与轮次匹配，陈旧的环境异步后代无法获得控制能力。不协作的进程内工作可能延迟取消，但所报告的静止状态仍然真实。 diff --git

An optional `ToolExecutionInput.signal` lets direct callers omit ownership, makes `exec.signal` optional in every tool body, and encourages registry fallbacks that cannot represent the caller's actual lifetime. + +The pipeline also has different mutability needs at different stages. Tool implementations, pre-policy, post-policy, and result observers only borrow cancellation state, while an around-dispatch wrapper must temporarily replace the signal to add a deadline or another lexical cancellation scope. One mutable public type either grants mutation too broadly or prevents that composition. + +Cancellation can arrive before policy, during approval, inside an around-dispatch wait, after a tool body starts, or while post-policy waits. One undifferentiated `ABORTED` result cannot tell durable consumers whether body side effects were possible. Racing a tool promise against cancellation is not a safe fallback because abandoned same-process work continues after the registry reports completion. + +## Decision + +`ToolExecutionInput.signal` is a required readonly `AbortSignal`. `ToolExecution.signal` and `ToolRunContext.signal` are therefore required and readonly as well. Every typed caller supplies the signal it owns; the registry provides no overload, default controller, never-abort sentinel, or convenience execution path. + +`ToolDefinition.execute(args, exec)` keeps its existing signature. `defineTool()` contextually types `exec.signal` as a required `AbortSignal`, so every registered TypeScript tool can observe or forward cancellation without a cast. First-party direct callers and nested Code Mode dispatches pass their current operation signal explicitly. + +The registry trusts this typed same-process contract. It does not perform runtime `AbortSignal` validation or add hostile-input tests for an omitted or malformed signal. Validation remains at parser/config, model/tool JSON, durable/file, worker, process, and wire boundaries; untyped JavaScript that violates the TypeScript interface has no compatibility contract. + +### Mutability follows the pipeline stage + +`ToolDispatchExecution` is identical to `ToolExecution` except that its required `signal` is mutable. Only the `tools/execute` waterfall receives this type. Pre-policy, post-policy, result observers, guards, and tool implementations receive readonly views of a private registry-owned mutable run object. + +An around-dispatch wrapper may replace `exec.signal` for its delegated lifetime but cannot typefully delete it or assign `undefined`. The registry captures the required caller signal outside that mutable object, fuses every wrapper replacement with the caller signal immediately before body invocation, removes dispatch-scoped listeners after settlement, and restores the required upstream signal unconditionally. + +### Cancellation codes record whether dispatch occurred + +`dsh-tools` exports `TOOL_ABORTED = 'ABORTED'` and `TOOL_ABORTED_BEFORE_DISPATCH = 'ABORTED_BEFORE_DISPATCH'`. The registry records body invocation immediately before calling `ToolDefinition.execute()`. + +`ABORTED_BEFORE_DISPATCH` carries `{ name: 'AbortError' }` and model text `Error: tool call aborted before dispatch`. It applies whenever cancellation prevents body invocation, including pre-aborted entry, cancellation during pre-policy or approval, an aborted wrapper signal, a wrapper success overtaken by caller cancellation before delegation, and agent-loop siblings skipped after turn cancellation. + +`ABORTED` carries model text `Error: tool call aborted` and applies only after the body was invoked, including cancellation while an around wrapper or post-policy listener waits after body completion. A denial, wrapper failure, tool failure, or post-policy failure remains more specific than generic cancellation. A timeout owned by timeout-policy remains `TOOL_TIMEOUT`, and contexts deferred before a successful outcome is replaced remain attached. + +### Pre-aborted entry short-circuits after materialization + +The registry first creates the call token and losslessly snapshots and freezes the arguments. A materialization failure wins even when the caller signal is already aborted. After successful materialization, a pre-aborted signal skips `tools/pre-execute`, approval, `tools/execute`, `tools/post-execute`, and the tool body, then publishes exactly one frozen authoritative `tools/result` with `ABORTED_BEFORE_DISPATCH`. + +### Started work still reaches quiescence + +Once a tool body starts, the registry awaits it. Cancellation reaches the body through the fused signal but never races or abandons its promise. A cooperative implementation stops or forwards cancellation and settles after its owned work reaches quiescence; an uncooperative same-process implementation can keep the registry pending indefinitely. Process, worker, network, and provider layers retain responsibility for their own termination mechanisms. + +This decision requires cancellation at the tool invocation seam only. Making signals required on asynchronous capabilities reachable from tool bodies is a separate migration proposed in [Required cancellation through tool-reachable capability seams](../../proposed/architecture/2026-07-19-required-cancellation-through-tool-capability-seams.md). + +## Verification + +[`execution-signal-types.spec.ts`](../../../../packages/core/tools/tests/execution-signal-types.spec.ts) proves the required exact signal types, readonly observer and tool views, mutable-but-required around-dispatch view, and `defineTool()` inference. [`tools.spec.ts`](../../../../packages/core/tools/tests/tools.spec.ts) covers pre-aborted materialization, phase skipping, policy and wrapper races, body invocation classification, caller-signal fusion, error precedence, context retention, and quiescent drainage. [`tool-calls.spec.ts`](../../../../packages/core/agent-loop/tests/tool-calls.spec.ts) and [`contract-regressions.spec.ts`](../../../../packages/core/agent-loop/tests/contract-regressions.spec.ts) cover balanced durable results for undispatched siblings. [`code-mode.spec.ts`](../../../../packages/core/tools/tests/code-mode.spec.ts) and first-party integration suites cover explicit forwarding, while [`timeout-policy.spec.ts`](../../../../packages/timeout/timeout-policy/tests/timeout-policy.spec.ts) preserves timeout ownership. + +No registry test can prove that arbitrary third-party same-process code observes the signal or stops in bounded time. Capability tests continue to prove cancellation and quiescence at the boundary that owns each side effect. + +## Alternatives considered + +**Keep the signal optional and synthesize a fallback.** Rejected because a registry-owned fallback has no caller lifetime to represent and preserves the exact omission the type should prevent. + +**Validate `AbortSignal` at runtime.** Rejected because this is a typed same-process seam, not a serialization boundary. Runtime checks would duplicate the static contract without making cooperative use enforceable. + +**Add `supportsCancellation` metadata, callback-arity checks, or signal-use linting.** Rejected because none proves that asynchronous work observes or correctly forwards cancellation. Availability is a type contract; behavior remains a tool and capability responsibility. + +**Expose one mutable execution type to every stage.** Rejected because observers and tool implementations only borrow the signal. Stage-specific types make replacement possible only where the pipeline owns that operation. + +**Forbid around wrappers from replacing the signal.** Rejected because deadlines and nested operational scopes need lexical derivation. Capturing and fusing the caller signal preserves composition without allowing detachment. + +**Race the tool promise against cancellation.** Rejected because it reports completion while side effects may remain live, violating the [quiescent-disposal rule](../../../../docs/defensive-patterns.md#dispose-must-reach-quiescence-not-just-request-it). + +## Consequences + +- TypeScript rejects every `ToolExecutionInput` that omits `signal`, every tool or observer mutation of a readonly signal, and every around-dispatch attempt to remove the signal. +- Durable consumers can distinguish calls whose body may have produced side effects (`ABORTED`) from calls that never entered the body (`ABORTED_BEFORE_DISPATCH`). +- The change is intentionally breaking under the repository's pre-release stance; no compatibility overload or runtime fallback remains. +- Cooperative tools stop promptly and reach quiescence; an implementation that ignores its signal remains observable as a pending call. +-

It exposes no generic plugin-shape, service-shape, or startup-assertion helpers and imports no product package. + +### Implemented checks + +The current 103-package workspace has 21 executable companions and 82 justified empty companions. + +| Owner | Runtime relationship | +|---|---| +| `dsh-session` | Strict sequence growth, turn/step enclosure, and same-step tool call/result pairing. | +| `dsh-agent` | Non-repeating agent status and terminal disposal transitions. | +| `dsh-scope` | Scoped-event carrier presence and routed-subject consistency. | +| `dsh-agent-loop` | Explicitly marked, frozen loop request reconstruction from the session event log. | +| `dsh-llm` | Stream block grammar, delta type/index matching, single usage, closed blocks, and terminal finish. | +| `dsh-llm-retry` | Durable retry records identify the open turn's latest closed step, remain unique per step, increase monotonically, and stay within retry and non-negative timer bounds. | +| `dsh-tools` | Monotonic pre/execute/post stages and immutable final execution/result snapshots. | +| `dsh-system-prompt` | Authoritative assembly section, tool, and variable data constraints. | +| `dsh-compact` | Compaction start/summary/end pairing, range endpoints, token counts, and successful-summary presence. | +| `dsh-hook-protocol` | Hook invocation/result correlation, dialect, identity, and duration constraints. | +| `dsh-sandbox-policy` | Durable `sandbox/mode` events use the closed sandbox-mode vocabulary. | +| `dsh-fs` | Filesystem decision/observation events carry usable target and version identities. | +| `dsh-goal` | Durable goal snapshots preserve source attribution, rendered content, revisions, lifecycle and timestamp relationships, and sequential admitted rounds. | +| `dsh-goal-session` | Goal-sourced continuation messages match the prompt reconstructed from the preceding durable goal state. | +| `dsh-subagent` | Provider add/remove and child start/end events preserve identity and pairing. | +| `dsh-permission` | Durable permission decisions name a preset in the active permission table. | +| `dsh-user-approval` | Approval asked/decided records pair by call and use valid outcomes and policies. | +| `dsh-workflow` | Workflow and child-agent start/end events preserve run metadata, identity, outcome, count, and error relations. | +| `dsh-tasks` | Current and terminal task snapshots preserve id/kind, owner, status, and timestamp relationships. | +| `dsh-tool-todo` | Durable whole-list snapshots use unique trimmed items, closed statuses, and at most one active item. | +| `dsh-time-context` | Plugin-attributed clock readings agree with the session's open turn, next pre-step position, and elapsed baseline; rendered time parses and does not postdate its event. | + +Session-backed companions validate existing durable events when they load, using the prefix preceding each candidate where the relationship depends on event order. Other checks observe the authoritative live event boundary or mutable service result. Validation runs before publication where accepting an invalid event would otherwise commit bad state. + +### Repository gate and tests + +`verify-package-invariants` discovers every workspace package and enforces companion source, exact-name registration, named-only Loader shape, `./invariant` exports, publication files, dependencies, TypeScript references, and bundle entries. Its AST rule rejects generated markers, default exports, and unexplained empty installers. A non-empty installer must accept and use the failure reporter, and registration must pass that checked local `install` function. The gate deliberately does not infer semantic quality from method names or helper calls. + +Vitest mounts `InvariantService` with `{ enabled: true }` for every package test topology and loads the owning companion. The invariant subpath path mapping resolves source companions instead of stale built output. Focused suites cover every executable companion's valid and invalid observations, and the exhaustive topology runs every source companion through the real Loader namespace normalization. An artifact gate stages each package's exact `npm pack` file inventory, imports its compiled `./invariant` self-reference under plain Node, and repeats that Loader-shape check, so an unpublished shared runtime chunk fails before release. Tests that synthesize event streams must produce a valid surrounding lifecycle unless the test is intentionally asserting a violation. + +## Alternatives considered + +- **Keep generated empty companions.** Rejected because an unexplained placeholder can survive after a package gains a meaningful runtime relation. +- **Require an assertion from every package.** Rejected because method-presence, plugin-shape, and fixed-example assertions duplicate stronger type, load, and unit-test contracts without checking runtime consistency. +- **Keep generic shape helpers in the service.** Rejected because they blur compile-time API validation with runtime invariants and encourage centrally defined product assumptions. +- **Move the product checks into the service.** Rejected because product vocabulary, dependencies, tests, and change ownership belong with the package that emits the data. +- **Register companions implicitly from root entrypoints.** Rejected because composition order and optional service presence would create hidden effects. + +## Consequences + +- Every package has visible ownership and publication wiring, but only packages with a plausible runtime relation add listeners or trace state. +- Empty companions remain reviewable decisions with package-specific explanations and fail the gate if the explanation is removed. +- Type declarations, Cordis loadability, plugin metadata, service method surfaces, and pure algebra remain covered by their owning compile, load, unit, or integration gates. +- Runtime failures identify the owning npm package and point to an inconsistent observation rather than restating a required API shape. +- The original selection, blocklist precedence, duplicate ownership, rollback, disposal, and HMR service contracts remain unchanged. diff --git a/.agents/notes/implemented/architecture/2026-07-19-package-invariant-runtime-contracts.zh.md

Putting all checks in one diagnostics package makes that package import product vocabularies from unrelated domains, centralizes tests away from their owners, and requires the central package to change whenever a product package adds or removes a check. + +Deployments also need more than presence or absence of one plugin. A standard composition should carry the known invariant contributions while permitting a global off switch and package-selective diagnostics. Selection must remain stable when a package loads later or reloads under HMR, and disabled contributions must not allow two plugins to claim the same package name silently. + +Package ownership must also be exhaustive. Without a mechanical repository rule, a new package can omit the companion, dependency, or publication wiring and remain invisible to diagnostics until a maintainer notices the gap. + +## Decision + +### One registry service, package-owned contributions + +`@deepseek-ai/dsh-invariants` is a product-independent Cordis service plugin that registers `ctx.invariants`. It owns configuration, registration uniqueness, child-fiber lifecycle, and package-attributed failures. It imports no session, agent, scope, or agent-loop package and contains none of their checks. + +Every workspace package publishes a `./invariant` companion plugin that registers its exact full npm name. A companion checks a meaningful event or mutable-data relationship when its owner has one; otherwise it carries an owner-specific explanation for its empty installer. Generated ownership placeholders and synthetic API-shape assertions are forbidden by the follow-up [runtime-contract Agent Note](2026-07-19-package-invariant-runtime-contracts.md). Package root entrypoints do not import or register diagnostics implicitly, so loading a root package does not change runtime checking or require the invariant service. + +### Configuration and selection + +```ts +interface Config { + enabled?: boolean + package_allowlist?: string[] + package_blocklist?: string[] +} +``` + +Defaults are `enabled: true`, `package_allowlist: []`, and `package_blocklist: []`. For a full registration name, selection is: + +```ts +export function selected(enabled: boolean, package_allowlist: RegExp[], package_blocklist: RegExp[], packageName: string): boolean { + return enabled + && ( + package_allowlist.length === 0 + || package_allowlist.some(pattern => pattern.test(packageName)) + ) + && !package_blocklist.some(pattern => pattern.test(packageName)) +} +``` + +Blocklist matches override allowlist matches. Each list entry is a case-sensitive JavaScript regex source compiled by `new RegExp(pattern)`. Matching is unanchored unless callers supply `^` and `$`; slash-delimited syntax and flags are not interpreted. Startup rejects blank, whitespace-padded, invalid, or duplicate sources within either list. A source that matches no loaded package remains valid because registration order, later loading, and HMR must not change config validity. + +### Registration and failure ownership + +The public registration boundary is `ctx.invariants.register(packageName, installer)`. It reserves one active registration per full npm package name even when filters disable installation, and returns the effect disposer. Disposing the companion or service releases the reservation and all contribution state. + +An enabled installer runs in a dedicated child Cordis fiber owned by the service. `InvariantInstaller.inject` declares the child fiber's service surface explicitly; the registry carries no product-specific dependency metadata. The service joins a returned installer promise before registration succeeds, so asynchronous startup checks remain transactional. The installer receives a bound `fail(message)` reporter. Calling it throws an `Error` subclass named `InvariantError` with stable code `INVARIANT` and the registering `packageName`; it does not extend a product-package error base. + +Registration setup is transactional. If an installer fails after registering listeners, the child fiber is disposed completely and the name reservation is released before the failure escapes. Filtered registrations create no child but retain their reservation until disposal. Reloading a companion therefore begins with one clean installer state; stateful contributions rebuild baselines from their owning services. + +The former functional-plugin entrypoint and one-argument `InvariantError` constructor are not retained as compatibility surfaces. The repository is pre-release and all call sites move to the service and package-attributed error together. + +### Initial stateful companions and exhaustive ownership + +| Companion entry | Registration name | Owned checks | +|---|---|---| +| `@deepseek-ai/dsh-session/invariant` | `@deepseek-ai/dsh-session` | session sequence, turn/step enclosure, and same-step call/result trace | +| `@deepseek-ai/dsh-agent/invariant` | `@deepseek-ai/dsh-agent` | agent-status transitions | +| `@deepseek-ai/dsh-scope/invariant` | `@deepseek-ai/dsh-scope` | scoped-event carrier presence and subject consistency | +| `@deepseek-ai/dsh-agent-loop/invariant` | `@deepseek-ai/dsh-agent-loop` | model-request reconstruction | + +These four owners supplied the initial stateful checks. The follow-up runtime-contract decision adds checks for seventeen more owners with real event or mutable-data relationships and records justified empty companions for the rest. Every companion is a separately bundled `./invariant` export with its own declarations and Loader-safe namespace plugin shape; the service package's own companion imports its local service type to avoid a self-dependency. + +`verify-package-invariants` discovers every workspace package and rejects missing companion source, generated markers, unexplained empty installers, non-empty installers that omit or ignore the reporter, foreign or unresolved registration names, missing `./invariant` exports or published files, missing invariant peer/development dependencies and project references, and bundle overrides that omit the companion entry. + +### Scoped-event semantic map + +The generated scoped-event subject resolver lives in `dsh-scope`, beside the contract and invariant that consume it. `gen-scoped-events` uses the root TypeScript Program to enumerate `this: Scoped` declarations, infer routing-key types from real `scopeTarget(base, key)` calls, and require one unambiguous payload subject or an explicit unsupported marker. The committed runtime map imports no event-owner package, so semantic completeness does not expand either the service or scope package's runtime closure. + +### Standard composition and SDK output + +The standard agent spine mounts the service and all four stateful companion subpaths, forwarding `enabled`, `package_allowlist`, and `package_blocklist` to the service. Generated SDK Cordis composition emits the same entries. A subpath entry adds its installable root npm package rather than treating the subpath as a package name. + +Workspace constraints recognize the separate invariant bundle, and package exports, project references, build configuration, dependency declarations, and the lockfile describe the same publication surface. Generated config catalogs, module graphs, and API documentation derive from those sources. + +## Testing + +Service tests cover defaults, global disablement, allow/block selection, blocklist precedence, anchoring, unanchored matching, case sensitivity, invalid configuration, zero-match patterns, late registration, duplicate ownership, disposal, rollback, and HMR re-registration. Owners with executable checks keep positive and negative behavior beside the companion source. + +Composition tests cover standard-spine forwarding and generated SDK entries. Loader tests preserve each companion namespace, while built plain-Node smokes exercise the compiled subpath exports. The scoped-event freshness gate reruns its semantic Program analysis. + +Every Vitest configuration loads a test host that mounts an explicitly enabled service before an ordinary Cordis root's first plugin and adds the current test package's companion. One exhaustive topology mounts all package companions once; focused service and owner tests construct their own invariant topology so they can exercise disablement, filtering, rollback, and reload without duplicate ownership. Gate tests also execute every companion's `apply` function and verify that it calls `register` with its manifest name, rather than accepting source text alone. + +## Alternatives considered + +- **Keep all checks in `dsh-invariants`.** Rejected because the registry would continue importing every checked product domain, owner changes would require central edits, and package tests would remain detached from the contracts they protect. +- **Let root package entrypoints register checks implicitly when `ctx.invariants` happens to exist.** Rejected because root behavior would depend on composition order and optional service presence, diagnostics could not be selected independently, and package loading would hide a registration effect outside an explicit companion. +- **Discover every `invariant.ts` file automatically at runtime.** Rejected because filesystem/package discovery is not a runtime ownership contract, makes bundled publication ambiguous, and cannot express explicit Cordis load order or dependency installation. Build-time generation, verification, and the test host may enumerate the source tree because they validate repository completeness rather than composing a shipped deployment. +- **Validate allow/block entries against the currently loaded package set.** Rejected because a zero-match pattern can intentionally target a later or HMR-loaded contribution; current load order must not determine config validity. + +## Consequences + +- Product packages own and test their relational assertions while the service stays product-independent. +- Every package pays the publication and dependency cost of a companion; only owners with a meaningful runtime relationship add listener or trace-state cost. +- Standard compositions can disable all checks or select package names without changing their plugin tree. +- Explicit companion entries make diagnostic cost and ownership visible in Cordis config and package exports. +- One selected executable contribution adds one child fiber and its listener/state cost; a selected empty contribution has no listener or trace-state cost, while filtered registrations retain only name ownership. +- Regex sources are deployment configuration and remain fixed until

Removing global capacity keeps measurement reusable when compact-basic is absent and prevents replay accounting from becoming another model registry. + +### Compact-basic resolves a target spec + +Compact-basic owns consumer policy. Top-level fields define defaults; `modelPolicies` contains partial overrides keyed by the exact `{ provider, model }` pair. Duplicate targets and unknown or invalid fields fail plugin load. `thresholdRatio` defaults to `0.8`, and retention defaults to `retainRatio: 0.16`; callers may use an absolute `retainTokens` instead, but the two retention forms are mutually exclusive. After inheritance, a ratio retention that is not below its threshold ratio also fails plugin load because no model capacity can make that policy valid. + +For proactive pressure, compact-basic reads the latest durable request route, resolves its adapter capacity and exact-target policy, and scales ratios into a `ResolvedCompactSpec`. It performs this resolution on every check, so a provider or model switch in one session changes capacity and policy immediately. An absolute retained budget that is not below the scaled threshold fails when the target capacity first makes that comparison possible. + +The same exact-target override can select summarization provider/model, summarization output cap, convergence retries, and overflow retry cap.

Manual proactive pressure fails with a target-specific configuration error; the automatic listener warns once per exact route and continues with full history. The same per-route suppression applies when resolved capacity exposes an invalid absolute retention budget, while unrelated operational failures remain independently visible. Canonical provider-confirmed overflow does not need capacity metadata: it bypasses the proactive threshold and normal retention budget, attempts one maximal balanced reduction, and preserves the original provider error unless replacement proves progress. + +## Testing + +Service tests cover detached context metadata, invalid adapter output, catalog independence, and default absence.

The same-session driver uses public agent and session events; its only core addition is the generic observe-before-cancel `agent/cancel-requested` notification needed by any lifecycle policy that must settle cancellation safely. + +Time-based `/loop` or scheduled execution is a third policy and is not implemented by this decision. It belongs with a scheduler rather than either goal family. + +### Package topology and owning verbs + +| Package | Repository category | Owned structures and verbs | +|---|---|---| +| `@deepseek-ai/dsh-goal` | `packages/goal/goal/`, domain service | Owns `GoalId`, compare-and-set `GoalRef`, `GoalSnapshot`, four-state `GoalPhase`, structured `GoalBlockReason`, process-local `GoalActivation`, replay folding, and `get`, `create`, `edit`, `pause`, `resume`, `complete`, `block`, `clear`, and `disarm` verbs. | +| `@deepseek-ai/dsh-tool-goal` | `packages/goal/tool-goal/`, model-facing consumer | Registers exclusive `get_goal`, `create_goal`, and `update_goal`; authenticates live turn provenance and narrows autonomous-round authority to completion or blocking reports with machine-routable reason codes. | +| `@deepseek-ai/dsh-goal-session` | `packages/goal/goal-session/`, continuation policy | Reserves, fences, admits, attributes, settles, cancels, and quiescently drains same-session goal rounds without importing the concrete loop. | +| `@deepseek-ai/dsh-commands` | `packages/ui/commands/`, UI registry | Owns `CommandDefinition`, discovery, scoped registration, direct dispatch, `CommandResult`, and request cancellation for human-only commands. | +| `@deepseek-ai/dsh-command-goal` | `packages/goal/command-goal/`, human-command producer | Registers `/goal` status, creation, edit, pause, resume, and clear over the goal domain for TUI and ACP. | +| `@deepseek-ai/dsh-tool-ralph` | `packages/workflow/tool-ralph/`, fixed workflow consumer | Registers `ralph({ objective, maxRounds? })`, validates the fresh structured provider and bounded `RalphRoundReport`, and returns `complete`, `blocked`, or `budget-limited`. | + +The detailed contracts live in the [goal-domain](2026-07-19-persisted-same-session-goal-domain.md), [model goal-tools](2026-07-19-model-facing-goal-tools.md), [goal-round driver](2026-07-19-same-session-goal-round-driver.md), [command registry](2026-07-19-plugin-command-registration.md), [human goal-command](2026-07-19-human-goal-command.md), and [Ralph workflow-tool](2026-07-19-fresh-agent-ralph-workflow-tool.md) Agent Notes. + +### Durable goal state and live authority + +One session has at most one current goal. Every non-clear mutation appends a full, versioned, model-visible goal snapshot through `Agent.inject()`; clear appends a revisioned tombstone. The session log is the only durable source of truth, so normal persistence, resume, compaction semantics, and `SessionStore.fork()` carry the goal without a second database or an artificial cancellation record. + +Durable phases are only `active`, `paused`, `blocked`, and `complete`. A blocked goal carries a required `GoalBlockReason` with a stable lower-kebab-case `code` and a non-empty human-readable `message`; usage limits, round exhaustion, model failures, and policy rejection are reason codes rather than extra lifecycle phases. Separate activation is `armed` or `disarmed` and is never persisted. Creation and explicit resume arm a goal; stop transitions, session start, fork replay, driver replacement, and driver teardown leave it disarmed. + +This separation makes session restoration observable and unsurprising. Reopening a session never starts goal work by itself. A later human prompt such as “continue”, “resume the goal”, or an equivalent request in any language gives the runtime-root model a new turn in which it may read the goal and call `update_goal(..., action: 'resume')`. `/goal resume` is the direct human-command path. The runtime authenticates that the request came from a live direct-human turn; prompt policy lets the model interpret whether the wording semantically authorizes creation or resumption. + +Forked sessions inherit the durable goal prefix because that is the natural replay result. The fork starts disarmed, so inheritance does not imply execution authority and no synthetic goal cancellation is inserted into history. + +`defaultMaxGoalRounds` is configurable and defaults to `256`. The cap counts only admitted goal rounds. `blockedAfterConsecutiveRounds` is separately configurable in the model-tool policy and defaults to `3`; it is a mechanical lower bound before an autonomous round may report a repeated blocker, not an evaluator of semantic sameness. + +### Same-session continuation + +The goal-round driver owns at most one pending reservation per exact live agent. It admits a reservation only when the goal is active and armed, the agent is idle, no competing human work exists, pending mutations are durable, the exact goal id/revision/round still matches, and downstream prompt policy accepts it. The prompt-submit fence checks those facts both before and after asynchronous listeners, preventing an edit, pause, human message, or unload race from admitting obsolete work. + +Only the durable goal-sourced `user/message` charges a round. Stale reservations become rejected zero-step turns without consuming the cap. A concurrent goal revision wins over settlement from an older round. + +Normal turn completion schedules another round only while the goal remains active, armed, and below its cap. Cancellation pauses. Rate limiting or quota exhaustion blocks with code `usage-limited`; cap exhaustion blocks with `round-limit`; queue failure uses `queue-failed`; turn errors, max-token stops, policy rejection, and unknown terminal results use their corresponding blocker codes. An independently composed request-recovery plugin may retry transient provider failures within that same turn; the goal driver never invents another round after an abnormal terminal outcome. A human can later authorize resume through ordinary language or `/goal resume`. + +### Human and model surfaces + +The human UX follows the compact Codex shape in the [public OpenAI Codex TUI dispatcher at commit `678157a`](https://github.com/openai/codex/blob/678157acaa819d5510adfe359abb5d0392cfe461/codex-rs/tui/src/chatwidget/slash_dispatch.rs#L750-L805): `/goal` shows status, `/goal ` creates, and `edit`, `pause`, `resume`, or `clear` perform direct lifecycle actions. The commit permalink keeps the researched grammar verifiable as Codex evolves. Status includes durable phase, admitted/capped rounds, and live armed/disarmed activation. Direct status and command output do not enter model history; accepted domain mutations remain reconstructable because the goal service records them. + +The model receives only `get_goal`, `create_goal`, and `update_goal`. It may create a goal when a direct human request clearly asks for substantial multi-round work, and it may infer that intent in any language. It must not turn routine one-turn work into a goal. Direct-human provenance is enforced in code; semantic interpretation remains model judgment. An autonomous goal round may report `complete` or `blocked` for the exact current goal round but cannot edit, pause, resume, or replace the human objective. + +TUI and ACP mount the shared command registry and complete goal stack by default and expose `/goal` through one producer. Every effective registered command is discoverable and invocable through every composed command adapter; a plugin incompatible with an application omits its command producer from that composition rather than relying on registry-level surface masks. The UI-less agent spine is opt-in so one-shot callers do not silently become multi-round operations. The headless CLI and JSON-RPC front doors do not consume the command plane; ordinary human text can still authorize model goal tools when that stack is composed. + +### Fresh-agent Ralph execution + +Ralph is a first-class model tool in its own plugin, demonstrating that a sophisticated fixed execution policy can be composed without a new loop core. The plugin owns a fixed workflow script over `ctx.workflows` and `ctx.subagents`; it does not create session-goal state or add a branch to `dsh-agent-loop`. + +Each round uses an explicit `WorkflowStartRequest.subagentProvider`, defaulting to `spawn`. The provider must exist, support structured output, and declare that it does not inherit parent context. Ralph also passes its resolved round cap as `WorkflowStartRequest.maxTotalAgents`; the worker engine validates both per-run policies before publishing work, so provider misconfiguration or an engine ceiling below the requested Ralph scale fails before a run exists. The child inherits cwd and lineage but receives only the immutable objective, round/cap, workspace-as-authority instruction, and previous normalized report. + +A report contains status, summary, evidence, next steps, and blocker text. Status-specific invariants and serialized size are validated inside the fixed script and again at the consumer boundary. `maxRounds` is configurable, defaults to `256`, and is the ceiling for a call override. `maxHandoffChars` defaults to `16384`; oversized reports fail rather than being silently truncated. `maxResultChars` separately defaults to `16384` and bounds the complete successful parent-facing text, including its envelope and truncation marker. + +An ordinary child failure ends the run without retry. The fixed script reports the failed round and last successful handoff when one exists, and the tool returns that state as an error instead of misclassifying it as a malformed report or budget exhaustion. Fatal workflow infrastructure failures can settle before the script returns that state; richer reason transport and retry policy remain deferred. + +The tool is foreground and process-local. The parent tool call waits for the terminal result, propagates cancellation into the worker engine, and awaits `run.dispose()` so child work is quiescent before return. The model sees one call and one bounded successful terminal result or an error; completion and blocker envelopes explicitly say that a worker reported the outcome rather than presenting it as independent certification. Intermediate child conversations remain outside the parent transcript. + +### External design lineage + +Codex provides the minimal observable goal UX used here: a persistent chat-attached target with set, view, edit, pause, resume, and clear controls. This implementation adopts that discoverability while using this repository's event-sourced goal record, plugin scopes, and runtime authority checks. + +Current [Claude Code goals](https://code.claude.com/docs/en/goal) reinforce the distinction between a goal that starts another turn after the previous turn and a timed `/loop`. Claude Code also uses a separate small-model evaluator after each turn. This implementation adopts the policy distinction but intentionally does not copy that evaluator: evaluator inputs, tool access, deterministic checks, provider choice, isolation, and authority need a separately designed plugin contract rather than an implicit self-certification layer. + +External products are comparators, not compatibility targets. The local source studies informed the boundaries, while the shipped interfaces follow this repository's “everything is a plugin”, model-visible-is-logged, explicit default resolution, and quiescent teardown rules. + +### Verification + +The six owning Agent Notes record unit, integration, process, snapshot, cancellation, replay, and built-runtime coverage. The stack exercises strict goal-record folding, compare-and-set races, session fork inheritance, disarmed restoration, natural-language direct-human authority, configurable caps and blocked thresholds, exact goal-round attribution, adapter-wide command discovery, and transcript isolation. Shipped keyless snapshots cover model goal creation/inspection through the headless app, multi-round same-session lifecycle and cancellation through ACP, direct `/goal` status without a model turn, and two real Ralph rounds through the headless app. The Ralph snapshot boots the worker-thread engine, spawn provider, structured-output runtime, and agent loop, then inspects distinct unseeded child logs and exact one-way bounded handoff while pinning the parent stream. Focused real-stack tests additionally cover completion, blocker and round-limit outcomes, malformed and oversized reports, ordinary child failure with the last good handoff, one phase event, and cancellation to child quiescence. Package sources remain under the repository's per-file 100% coverage gate, and built-binary tests cover installed-artifact resolution. The implementation experience is recorded in the root testing policy: every non-trivial model- or human-visible change must carry a real-example keyless snapshot in the same PR rather than relying on package-only or mock-only fixture coverage. + +## Alternatives considered + +- **Implement the original universal loop capability seam** — rejected because `Evaluator`, `BudgetPolicy`, `RoundHandoff`, `GoalReflector`, background task ownership, persistence, and scheduling do not form one coherent mandatory abstraction. Building all of them before their first concrete consumers would create broad speculative surface and duplicate existing session, workflow, subagent, and task machinery. +- **Implement only same-session goals** — rejected because fresh-context iteration is materially different and is a valuable demonstration of the plugin architecture. Ralph belongs as a fixed workflow consumer with explicit context reset. +- **Put Ralph inside the goal-round driver** — rejected because same-session goals deliberately preserve one conversation while Ralph deliberately removes it. Combining them would make activation, replay, handoff, and UI state ambiguous. +- **Treat a fork as a fresh Ralph child** — rejected because a fork carries a conversation prefix. Fresh children plus workspace state and one explicit report are easier to bound and replay without a synthetic cancel record. +- **Copy Claude Code's evaluator into the first goal implementation** — rejected because a transcript-only model evaluator is one useful policy, not a generally trustworthy completion certificate. Deterministic evaluation and isolation must remain possible, so the evaluator is deferred until its authority and provider seam are designed. +- **Automatically continue after session restore** — rejected because opening a session is observation, not authority to spend resources. Durable state is restored while activation waits for a new human prompt. +- **Route `/goal` through the model** — rejected because status and explicit lifecycle controls should be deterministic, token-free UI actions; ordinary natural-language prompts remain the semantic model path. +- **Modify the concrete agent loop with goal or Ralph modes** — rejected because public queue, prompt, session, cancellation, workflow, and subagent seams already support both policies. The generic cancel-requested observation is the only core coordination addition. + +## Consequences + +- Goal-based execution ships without one overloaded “loop” object: same-session continuation and fresh-agent iteration have explicit, separately testable contracts. +- Durable goal history is replayable and forkable, while process-local activation prevents accidental work on resume. +- Humans receive a small Codex-shaped UX; models receive a compact provenance-checked tool surface; deployments can remove either independently. +- Ralph demonstrates a nontrivial fixed policy entirely as a plugin over existing workflow and subagent primitives. +- Round limits are generous by default but remain deployment-controlled. They bound iterations, not tokens, price, elapsed time, or external side effects. +- The original proposal's evaluator, budget, reflector, background-task, CLI, and generic loop-session architecture is intentionally not part of the implemented public surface. + +## Known limitations and deferred work + +- **Independent evaluation** — same-session completion/blocking and Ralph terminal status are model or worker declarations. A separate evaluator, evaluator-driven feedback round, completion certificate, deterministic checker, adversarial verifier, and criteria/executor/isolation contract remain deferred. +- **Aggregate budgets** — `maxGoalRounds` and Ralph `maxRounds` are the only aggregate effort limits. Token, currency, elapsed-time, provider-usage, and per-round price admission policies are absent. +- **No persistent autonomous runner** — same-session goal facts persist, but activation and scheduling are process-local and deliberately wait for human input after restore. Ralph runs are foreground and cannot resume after process loss. Background collection, restart recovery, and unattended resident execution are deferred. +- **No time scheduler** — interval `/loop`, cron, proactive maintenance, and cloud or desktop scheduling are outside this decision. +- **No generic loop journal or execution-world rewind** — session replay reconstructs model-visible goal history, not prior files, processes, environment, credentials, or external side effects. Ralph treats the current workspace as authority and carries no cross-run journal. +- **No goal reflector** — concern events, automatic no-progress heuristics, goal revision by an independent reflector, stuck-pattern detection, and `loop_split` are not implemented. Humans can edit, pause, clear, or resume the goal directly. +- **Ralph policy remains narrow** — one round creates one fresh child; within-round fan-out, evaluator/worker role separation, dynamic provider/model selection, and structural recursive-Ralph tool denial need separate policy surfaces. Prompt guidance is not enforcement. +- **Ralph does not retry a failed child** — an ordinary failure preserves the failed round and last good handoff, while fatal workflow infrastructure failures can end before that state is available. Retry count, backoff, and richer failure transport need separate policy and seam design. +- **Portable UI remains modest** — TUI and ACP render plain-text goal status and generic Ralph cards. There is no continuous status widget, reconnectable command output, modal goal editor, or command plane in the headless CLI or JSON-RPC front doors. diff --git

+这种分离让会话恢复可观察且符合直觉。重新打开会话绝不会自行开始目标工作。随后的人类提示词，例如“继续”、“恢复目标”或任何语言中的等价请求，会给运行时根 agent 的模型一个新 Turn；模型可在其中读取目标并调用 `update_goal(..., action: 'resume')`。`/goal resume` 是直接人类命令路径。运行时认证请求来自实时直接人类 Turn；提示策略让模型解释措辞在语义上是否授权创建或恢复。 + +fork 会话会继承持久目标前缀，因为这是自然的重放结果。fork 从未激活状态开始，因此继承不等于执行权限，历史中也不会插入合成目标取消。 + +`defaultMaxGoalRounds` 可配置且默认为 `256`。该上限只计算已接纳目标回合。`blockedAfterConsecutiveRounds` 在模型工具策略中单独配置且默认为 `3`；它只是在自治 Round 报告重复阻塞前的机械下限，不是对语义相同性的评估器。 + +### 同会话续行 + +目标回合驱动器为每个准确实时 agent 至多拥有一个待定预留。只有目标处于活跃且已激活状态、agent 空闲、不存在竞争性人类工作、待定变更已经持久、准确目标 id/修订号/Round

分发器](https://github.com/openai/codex/blob/678157acaa819d5510adfe359abb5d0392cfe461/codex-rs/tui/src/chatwidget/slash_dispatch.rs#L750-L805)中的紧凑形态：`/goal` 显示状态，`/goal ` 创建目标，而 `edit`、`pause`、`resume` 或 `clear` 执行直接生命周期操作。该提交永久链接让研究所得语法在 Codex 演进时仍可验证。状态包含持久阶段、已接纳/上限 Round 数以及实时已激活/未激活状态。直接状态与命令输出不会进入模型历史；已接受领域变更仍可重建，因为目标服务会记录它们。 + +模型只接收 `get_goal`、`create_goal` 和 `update_goal`。当直接人类请求清楚要求大量多 Round 工作时，模型可以创建目标，并且可以从任何语言推断该意图。它不得把日常单 Turn 工作变成目标。直接人类来源由代码强制执行；语义解释仍是模型判断。自治目标 Round 可以为准确当前目标 Round 报告 `complete` 或 `blocked`，但不能编辑、暂停、恢复或替换人类目标。 + +TUI 与 ACP 默认挂载共享命令注册表和完整目标栈，并通过同一个生产方暴露 `/goal`。每条有效已注册命令都能被每个已组合的命令适配器发现和调用；若插件与某应用不兼容，该应用组合会省略其命令生产方，而不是依赖注册表层面的表面掩码。无 UI agent spine 要求显式选择加入，以免单次调用方静默变成多 Round 操作。无头 CLI 与 JSON-RPC 前端不消费命令平面；挂载目标栈后，普通人类文本仍可授权模型目标工具。 + +### 全新 agent Ralph 执行 + +Ralph 是位于自有插件中的一等模型工具，展示了复杂固定执行策略可以在没有新 loop 核心的情况下组合完成。该插件拥有构建在 `ctx.workflows` 与 `ctx.subagents` 之上的固定工作流脚本；它不会创建会话目标状态，也不会为 `dsh-agent-loop` 增加分支。 + +每个 Round 都使用显式 `WorkflowStartRequest.subagentProvider`，默认为 `spawn`。该 provider 必须存在、支持结构化输出，并声明不继承父上下文。Ralph 还会把解析后的 Round 上限作为 `WorkflowStartRequest.maxTotalAgents` 传递；工作线程引擎会在发布工作前验证两项每次运行策略，因此 provider 配置错误或低于所请求 Ralph 规模的引擎上限会在运行存在前失败。子 agent 继承 cwd 与谱系，但只接收不可变目标、当前 Round/上限、以工作区为权威的指令和上一份规范化报告。 + +报告包含状态、摘要、证据、下一步与阻塞文本。固定脚本内部和消费者边界都会验证状态专用不变量与序列化大小。`maxRounds` 可配置，默认为 `256`，并作为调用覆盖值的上限。`maxHandoffChars` 默认为 `16384`；过大报告会失败，而不会被静默截断。`maxResultChars` 单独默认为 `16384`，并限制面向父级的完整成功文本，包括外层文本与截断标记。 + +普通子 agent 失败会结束运行且不重试。固定脚本会报告失败 Round，并在存在时带回上一份成功交接；工具会把该状态作为错误返回，而不会误判为畸形报告或预算耗尽。致命工作流基础设施错误可能在脚本返回该状态前结算；更丰富的原因传输与重试策略均予以延期。 + +该工具位于前台且只存在于进程内。父工具调用等待终止结果，把取消传播到工作线程引擎，并等待 `run.dispose()`，因此返回前子工作已达到静止。模型只看到一次调用，以及一份有界成功终止结果或一个错误；完成与阻塞的外层文本会明确说明结果由工作者报告，而不会呈现为独立认证。中间子 agent 对话不会进入父转录。 + +### 外部设计谱系 + +Codex 提供了这里采用的最小可观察目标 UX：一个附着于聊天的持久目标，以及设置、查看、编辑、暂停、恢复与清除控制。本实现采用这种可发现性，但使用本仓库的事件溯源目标记录、插件作用域与运行时权限检查。 + +当前 [Claude Code goals](https://code.claude.com/docs/en/goal) 进一步验证了“前一 Turn 后启动另一 Turn 的目标”和定时 `/loop` 之间的区别。Claude Code 还会在每个 Turn 后使用独立小模型评估器。本实现采用策略区分，但有意不复制该评估器：评估器输入、工具访问、确定性检查、provider 选择、隔离与权限需要单独设计的插件契约，而不是隐式自我认证层。 + +外部产品只是比较对象，不是兼容目标。本地源码研究帮助确定边界，而交付接口遵循本仓库“一切皆插件”、模型可见即可记录、显式解析默认值与静止拆卸规则。 + +### 验证 +

失败、单个阶段事件，以及取消后达到子 agent 静止状态。包源码继续受仓库逐文件 100% 覆盖率门禁约束，构建后二进制测试覆盖已安装产物解析。实现经验已记录进根测试策略：每项非平凡的模型或人类可见变更都必须在同一 PR 中携带真实示例无密钥快照，而不能依赖仅包级或仅模拟夹具的覆盖。 + +## 考虑过的替代方案 + +- **实现原始通用 loop 能力接缝**——不予采纳，因为

Letting each child inherit the parent conversation would also defeat context reset and make replay depend on a growing implicit prefix.

It registers `ralph({ objective, maxRounds? })`, owns a fixed workflow script, and depends only on `ctx.tools`, `ctx.systemPrompt`, `ctx.workflows`, and `ctx.subagents`. A Ralph run is not a session goal, creates no goal state, and requires no branch in the concrete agent loop. + +The tool is foreground-only. The calling agent parents every child for cwd and lineage, the parent tool call waits for the complete run, and the parent step's abort signal cancels the workflow. `run.dispose()` is awaited on every path, so cancellation reaches the worker engine's bounded settlement and child quiescence before the call returns. + +### Per-run workflow provider route + +`WorkflowStartRequest` gains optional `subagentProvider`. The worker-thread engine resolves that explicit per-run value before falling back to its configured provider, requires the selected normalized route to be registered before publishing the run, and uses it for every `agent()` call. The script cannot observe or replace this route. The ordinary `workflow` tool leaves the field unset and exposes no new model argument, so general workflow behavior and provider policy stay unchanged. + +The Ralph plugin's `subagentProvider` defaults to `spawn`. Immediately before a call it requires the named provider to exist, support structured output, and report `inheritsParentContext: false`; a fork-like or incapable provider fails loudly before workflow start. Provider lookup remains call-time because effect-scoped provider registration can change under HMR. + +### Per-run workflow child ceiling + +`WorkflowStartRequest` also gains optional `maxTotalAgents`. The worker-thread engine requires a positive safe integer no greater than its configured deployment ceiling and installs the resolved value in that run's worker limits before publishing the run. Ralph passes its resolved `maxRounds` as this ceiling, so the fixed loop's round budget and the generic runaway-child backstop cannot disagree. The ordinary workflow tool leaves the field unset and keeps the engine default. + +### Ralph rounds and handoff + +The hierarchy is Ralph Run → Ralph Round → fresh child Turn → Step. One Ralph round creates exactly one child through the selected provider. Spawn gives that child a distinct session with no seed while preserving the parent's cwd, so the shared working tree is the durable authority and neither parent conversation nor prior child history enters the request. + +The fixed prompt passes only the immutable objective, current round and cap, a workspace-as-authority instruction, and the previous structured report. A `RalphRoundReport` contains `status: continue | complete | blocked`, `summary`, `evidence`, `nextSteps`, and `blocker`. Strings must be normalized; `continue` requires next steps and no blocker, `complete` requires evidence with no next steps or blocker, and `blocked` requires a concrete blocker. The script validates semantics and serialized size before the report can become the next handoff; the consumer validates the materialized terminal value again across the workflow seam. + +`maxRounds` defaults to `256` and is also the deployment ceiling for a call override. `maxHandoffChars` and `maxResultChars` each default to `16384`. All are positive safe-integer config values. Oversized handoffs fail rather than being silently truncated; `maxResultChars` separately bounds the complete successful parent-facing text, including its envelope and truncation marker, without changing cross-round state. After a `continue` report at the last permitted round, the fixed script returns `budget-limited`; `complete` and `blocked` return immediately with the final report and number of rounds started. + +The workflow language maps a normally settled but unsuccessful child to `null`. The fixed script detects that value before report validation and returns `round-failed` with the failed round plus the last successful handoff when one exists; the tool turns it into an error instead of misclassifying it as a malformed report or budget exhaustion. Ralph adds no retry policy. Fatal provider-start, transport, worker, and workflow errors remain generic workflow failures because the workflow seam does not carry a recoverable child report on those paths. + +### Model and UI surface + +The model may supply only `objective` and optional `maxRounds`; provider selection, report schema, handoff cap, and script are deployment-owned. A fixed prompt section says to use `ralph` only when the direct human explicitly asks for Ralph or fresh-agent iteration, and distinguishes it from same-session goals, bounded delegation, and general fan-out workflows. This is guidance rather than a new goal UX state machine. + +ACP and terminal presentation use a generic `ralph` card whose raw input is the objective. Successful completion and blocker envelopes say that a worker reported the outcome rather than presenting it as independent certification. The parent transcript retains the original tool call and one bounded successful terminal report or an error, not intermediate child messages. Shipped headless, TUI, and ACP compositions load the plugin beside the existing workflow engine; JSON-RPC remains unchanged because its default composition does not expose workflows. + +## Testing + +Unit tests cover config and call-cap resolution, provider capability rejection, fixed start-request routing and child ceiling, all successful terminal outcomes, ordinary child-failure envelopes, malformed and oversized boundary values, exact successful-result truncation, abort timing, disposal, render intent, prompt lifecycle, and namespace-plugin shape at per-file 100% coverage. Worker-engine tests prove synchronous provider-route validation, per-run child ceilings below the deployment ceiling, and that a provider override selects every child without changing the configured default, including the built `lib/worker.cjs` under plain Node. + +A keyless real-stack integration drives the fixed script through the actual worker-thread engine, spawn provider, structured-output runtime, and agent loop. It proves distinct child identities, absent `seedLength`, inherited cwd, no parent-history markers in either child request, exact previous-report handoff only in the following round, one phase event, terminal completion, and disposal of both children. The same real stack covers blocker and round-limit outcomes, unnormalized and semantically invalid reports, oversized handoffs, ordinary child failure with the last good handoff, and cancellation to child quiescence. A shipped keyless headless snapshot additionally boots the real `examples/headless-agent` composition, invokes `ralph`, pins the parent stream transcript, and inspects persisted logs for two distinct unseeded child sessions and the round-one handoff appearing only in round two. Tool tests pin generic call/result presentation, while ACP replay header snapshots pin the shipped schema and prompt-guidance transcript surface. + +## Alternatives considered + +- **Put Ralph in the same-session goal driver** — rejected because goal rounds intentionally preserve one conversation, while Ralph's defining property is a fresh context per round; combining them would make goal lifecycle and child orchestration inseparable. +- **Expose a `fresh` or loop flag on the general workflow tool** — rejected because the model-written script surface should remain general and provider-neutral; Ralph's fixed report protocol and stop policy deserve one reviewable consumer. +- **Use `subagent_fork` for replay convenience** — rejected because inherited completed turns are implicit, growing handoff state and violate the fresh-context contract.

A user needs to inspect the exact current phase and round budget without asking the model, explicitly pause or clear work without spending a model turn, and rearm a restored active goal after the required post-resume human decision. Implementing those actions independently in TUI and ACP would duplicate parsing, let the surfaces drift, and risk routing an unknown or unavailable command into the model. + +The command must also respect the goal design's two kinds of state. Durable phase, objective, revisions, and rounds come from the session log; process-local activation decides whether an active goal may continue automatically. Showing only “active” after a resume would be misleading when the restored goal is intentionally disarmed and waiting for human authorization. + +## Decision + +`@deepseek-ai/dsh-command-goal` in `packages/goal/command-goal/` is a command producer over `ctx.commands` and `ctx.goals`. It registers one global `goal` definition, so every command adapter in the composition discovers the same command; an incompatible app omits this producer rather than masking its registration at an adapter. The handler receives the exact target agent from command dispatch, reads or mutates that agent's goal through the domain service, and returns direct plain-text UI output. It does not import either adapter or the concrete agent loop. + +The command follows the compact Codex shape in the [public OpenAI Codex TUI dispatcher at commit `678157a`](https://github.com/openai/codex/blob/678157acaa819d5510adfe359abb5d0392cfe461/codex-rs/tui/src/chatwidget/slash_dispatch.rs#L750-L805): bare status, a free-form objective, and `clear`, `edit`, `pause`, or `resume` controls. The commit permalink makes the researched grammar durable even as Codex evolves. This repository keeps its own event-sourced state, round-count policy, and post-resume activation rule rather than copying Codex's SQLite, token budget, or automatic-resume behavior. + +### Grammar and lifecycle verbs + +`/goal` reports the objective, human-readable durable phase, `roundsStarted/maxGoalRounds`, process-local `armed` or `disarmed` activation, and commands meaningful from that state. With no current goal it reports that fact plus complete usage. Reading status adds no session event. + +`/goal ` creates an active armed goal. A completed goal may be replaced, which creates a fresh goal identity through the existing domain rule. Any unfinished goal makes the command fail directly with instructions to use inline edit or explicit clear. The generic command service deliberately has no modal confirmation API, so silently clearing and creating two durable records would manufacture destructive consent and expose a non-atomic failure window. + +`/goal edit ` edits the current non-complete goal without changing phase or activation. On a completed goal it creates a fresh active goal because the domain does not permit completed state to resume and a new completion objective is a new goal identity. Bare `edit` is an error rather than an editor launch because ACP's shared unstructured command contract has no portable modal editor. + +`/goal pause`, `/goal resume`, and `/goal clear` call the matching compare-and-set domain verbs against the current view. Resume covers both stopped durable phases and an active-but-disarmed goal after session resume, fork, or driver replacement. Domain rules still reject exhausted round caps, redundant active/armed resume, invalid phase transitions, and stale identity. Clear removes the current pointer while the session log retains the revisioned tombstone and earlier snapshots. + +Control words are ASCII-case-insensitive after outer whitespace trimming. They are controls only when they occupy the full suffix; any other non-empty text is an objective. This matches the predictable free-form command rule: `/goal pause after verification` is a goal objective, not a partially parsed pause command. + +### Output and failure boundary + +Status output omits branded ids and compare-and-set revisions because those are model/plugin coordination details rather than human controls. It includes activation because that fact changes whether work will continue, and a blocked goal includes its durable policy code and human-readable explanation. Command hints are derived from the exact state: an armed active goal offers pause, a disarmed active or paused/blocked goal offers resume, and a completed goal offers replacement or clear. + +Expected `GoalError` failures become one stable, branded-id-free `CommandResult.error`, so domain diagnostics do not leak compare-and-set internals into the human surface and invalid operations never enter model history. The current status supplies the actionable state-specific recovery. Other exceptions remain adapter-visible command failures; treating programmer faults as ordinary domain errors would hide defects. The command handler performs only synchronous domain mutations, so request cancellation is decided by the command registry before the mutation begins and there is no escaped asynchronous side effect to unwind. + +Generic slash input, status text, and errors are not persisted. Successful goal mutations use the existing `Agent.inject()` path, producing the raw model-visible goal snapshot or clear tombstone that persistence already owns. The command therefore changes no session format and introduces no second audit record that could disagree with the domain event. + +### App composition + +`agent-spine-demo` accepts an optional `goals` composition object containing the goal-domain and model-tool owner configs. Omission or `false` leaves the stack unmounted. This explicit opt-in is important for headless one-shot callers: their result API settles one correlated physical turn and must not silently become a long-running logical goal operation. + +The interactive app bundles make the opposite product choice. ACP and TUI default `goals` to the owner defaults and mount the goal domain, model tools, same-session driver, command registry, and this producer. Both apps accept `goals: false` as one coherent stack opt-out. The Python SDK runtime closure ships this producer alongside ACP, commands, and the goal stack so an external `cordis.yml` can compose the same command. + +## Testing + +The producer suite uses the real command registry, goal service, agent registry, and session log. It covers Loader-safe exports, registry discovery, disposal, empty status, objective parsing, unfinished replacement refusal, inline edit, completed replacement, all missing-state controls, pause/resume/clear, every durable phase, blocked code/explanation presentation, armed/disarmed presentation, sanitized domain errors, unexpected failures, and persisted mutation records. App composition tests cover explicit spine opt-in, TUI/ACP defaults, coherent opt-out, forwarded domain/tool config, command discovery, the packaged-runtime closure, and the expanded model-tool assembly. A keyless snapshot boots the shipped ACP application, observes its advertised `/goal` metadata, invokes `/goal` directly, and pins the no-model-turn result; the surrounding ACP snapshots also pin the goal tool schemas in that composition. + +## Alternatives considered + +- **Let the model handle `/goal` as ordinary text** — rejected because status and direct lifecycle actions would cost a model turn, could be reinterpreted, and would not provide deterministic ACP discovery. +- **Implement separate TUI and ACP handlers** — rejected because grammar, error behavior, and goal-state formatting would drift and optional deployments could not add or remove the capability as one effect. +- **Add modal editing and replacement confirmation to `ctx.commands`** — rejected because the existing cross-surface contract is unstructured input plus direct output; a general interaction protocol needs more than this one producer. +- **Silently replace an unfinished goal** — rejected because it combines clear and create without atomicity or explicit destructive intent. +- **Expose goal id and revision in human status** — rejected because human actions always target the exact current view inside one synchronous handler; those fields add implementation noise without preventing another race. +- **Enable goals unconditionally in the UI-less spine** — rejected because one-shot SDK/CLI settlement is a physical-turn API, not a goal-operation API. + +## Consequences + +- TUI and ACP expose one Codex-shaped `/goal` command supplied by a removable plugin. +- Human status distinguishes durable phase from live activation and reports the exact goal-round cap. +- Direct pause, resume, clear, creation, and edit consume no model turn while their accepted mutations remain reconstructable from the session log. +- Restored sessions wait for a human decision; `/goal resume` is the literal command path, while an ordinary prompt in any language may authorize the model tool path. +- Headless compositions retain one-turn behavior unless they explicitly opt into goals and define their own long-running settlement contract. + +## Known limitations and deferred work + +- The portable command contract has no modal editor or confirmation interaction; inline edit and explicit clear are intentional until a general cross-surface interaction primitive exists. +- `/goal` does not accept a per-command round cap. Deployment config owns the default, and the authorized model tool can edit a cap after direct human instruction. +- TUI and ACP render portable plain text rather than a continuously updated goal status widget.

The names and read-create-update shape follow Codex's compact goal tool surface while the authority rules use this repository's public agent, session, tool, and goal seams. + +### Tools and model contract + +`get_goal()` returns the current goal or `null`. A non-null result contains the compare-and-set id and revision, objective, durable phase, admitted and maximum goal rounds, any blocker reason, plus the process-local activation observation. `create_goal(objective, max_goal_rounds?)` creates one long-running same-session objective. `update_goal(goal_id, revision, action, objective?, max_goal_rounds?, blocked_reason?)` supports `edit`, `pause`, `resume`, `complete`, and `blocked`; replacement fields are valid only for `edit`, while a non-empty `blocked_reason` is required only for `blocked` and persists under the stable `model-reported` code. + +The prompt tells the model that it may infer goal intent from a direct human request in any wording or language, but should not convert routine single-turn work into a goal. It must read the current goal before updating and copy the exact id and revision. On a restored or forked active-but-disarmed goal, a semantic human request to continue is grounds for `resume`. Completion is reserved for an achieved objective, and difficulty or uncertainty alone is not a blocker; a block report must name the concrete condition. + +All three tools use exclusive execution so a model-ordered batch observes prior mutations and their new revisions. Results are compact JSON. ACP presentation is a pure function of arguments and uses generic read or mutation cards; activation is reported only as live observation and is never written into replay state. + +An autonomous goal round that successfully reports completion or blocking contributes the existing terminal `agent/turn-stop` decision for that physical turn, preventing an unnecessary follow-up request. Direct-human mutations do not contribute a terminal stop: the assistant can acknowledge the change, and concurrent human steering remains available to ordinary continuation folding. + +### Execution authority + +Every call requires an `exec.agent` that is the exact running object in `AgentRegistry`, is the current inherited driver initiator, and has an open turn. These are execution-time checks and cannot be bypassed by prompt injection or hand-authored tool arguments. + +Create, edit, pause, and resume additionally require an accepted user message or user steering event in the current turn of a runtime-root agent. Root ownership is derived from the live agent graph rather than durable fork ancestry: a resumed fork can receive direct human authority, while a live child remains a subagent and cannot mutate these states. User source is a host attestation: `Agent.send()` and `steer()` default an omitted source to `{ kind: 'user' }`, so non-human producers must label their own content. The runtime proves provenance, not whether the human's wording semantically warrants creation or resumption; that interpretation remains with the model. + +Complete and blocked accept either direct-human authority or the exact current goal round. Goal-round authority requires a goal-sourced `user/message` whose goal id, revision, and round all equal the folded current goal. It grants only the two terminal reports. Direct human authority may stop a goal immediately. + +### Blocking threshold + +`blockedAfterConsecutiveRounds` is a validated positive safe-integer configuration with default `3`. When an autonomous goal round calls `blocked`, the plugin mechanically requires at least that many admitted rounds and a non-empty explanation; the configured value also appears in model guidance. The runtime cannot determine whether those rounds encountered the same blocking condition, so semantic equivalence remains a model judgment. This count is deliberately separate from the goal's generous continuation cap. + +## Testing + +Unit coverage pins registration and disposal, exclusive scheduling, generated prompt policy, generic presentation, direct-human creation in a non-English turn, exact/stale/non-running agent and driver checks, live-child rejection, resumed-fork root authority, steering, mismatched initiators, read/create/edit/pause/resume behavior, conditional blocker explanations, rearming after a session-start edge, authority-before-conditional-argument failures, exact goal-round completion, autonomous-only terminal stopping, the configured blocking threshold, and immediate human blocking. A keyless replay snapshot mounts the goal domain and tools into the real headless one-shot application, drives `create_goal` and `get_goal` through the shipped loop and persistence stack, pins its stream-json transcript, and inspects the externally persisted goal change.

Treating that objective as an in-memory loop variable loses it on process restart, while putting it only in UI state makes model behavior impossible to reconstruct. Treating every session turn as progress also charges unrelated human messages against an automatic-work budget. + +Durable lifecycle and permission to continue are different facts. A session may retain an active objective after restart or fork, but silently starting work when a user opens that session is surprising. The domain needs replayable state without persisted auto-execution authority, and it must remain a plugin on the public agent/session seams rather than a special case in the concrete loop. + +## Decision + +`@deepseek-ai/dsh-goal` in `packages/goal/goal/` owns one current same-session goal through `ctx.goals`. A goal has a branded id, objective, durable phase, compare-and-set revision, and `maxGoalRounds`. `defaultMaxGoalRounds` is a validated deployment setting with default `256`; `create()` materializes it internally before mutation rather than exposing resolution as another service verb. + +The durable phases are `active`, `paused`, `blocked`, and `complete`. A blocked snapshot includes a policy-owned lower-kebab-case code and a normalized free-form message, so usage limits, round caps, execution failures, and human-input dependencies share one lifecycle state without losing their cause. A separate live activation is `armed` or `disarmed`. Creation and explicit resume arm activation; pause, completion, blocking, and clear disarm it. Edits preserve activation and any blocker reason; resume and completion clear that reason. Activation is never part of the persisted snapshot. + +### Durable record and replay + +Every non-clear mutation uses `Agent.inject()` to append a model-visible `context/message` containing a versioned full snapshot; the session projects that content verbatim. Clear appends a revisioned tombstone. The context source is `{ kind: 'goal', goalId, revision, round: 0 }`; metadata and rendered `...` content must agree exactly. This descriptive delimiter follows the repository's existing `` convention and [Anthropic's published guidance to structure mixed prompt content with consistent descriptive XML tags](https://platform.claude.com/docs/en/build-with-claude/prompt-engineering/claude-prompting-best-practices#structure-prompts-with-xml-tags). That is public model-experience prior art, not evidence about any provider's proprietary training corpus. The session log is the only durable source of truth, so persistence and fork inherit goal records without another database or header field. + +The replay fold validates JSON shape, source attribution, rendered content, fresh ids, revision continuity, lifecycle transitions, counters, and monotonic per-goal timestamps. Goal rounds are positive sequential `user/message` source numbers for the current active revision and cannot exceed `maxGoalRounds`; ordinary session turns do not affect the counter. A malformed current-format record fails replay rather than being ignored or repaired. + +When `Agent.inject()` defers a mutation inside an active tool batch, the service overlays the accepted payload in process memory so a later mutation can use its new revision. Reconciliation removes only an exact matching payload when the FIFO append becomes visible; reentrant append observers project each mutation exactly once. Incremental replay advances its cursor after each valid event and remains positioned at the first corrupt event, so later reads report the same durable fault. The durable log remains authoritative after restart. + +### Lifecycle and live activation + +At most one goal is current. Create requires no current non-complete goal and always generates a revision-one id not used earlier in the session; a completed goal may be replaced. Every other mutation carries the expected `GoalRef`, and stale ids or revisions reject. Resume accepts a paused or blocked phase, or a disarmed active goal, only when the round cap has remaining capacity. The domain validates blocker reason shape but deliberately leaves reason codes and the decision to block to policy consumers. + +A cache built from any seed starts disarmed, and every `agent/session-start` edge disarms it again. `GoalService.disarm(agent)` also lets a lifecycle owner remove process-local authority without a session event, revision change, or `goal/changed` notification. Resume, fork, and continuation-driver replacement therefore preserve the durable objective and history but never initiate work on their own. A later human prompt can be interpreted by the model, whose policy surface may explicitly call resume and arm the goal. + +### Service boundary + +The service accepts only the exact live `Agent` object registered under its id. Successful mutation injection emits the scoped `goal/changed` event with contained listener failures. Policy consumers use this service plus the public `Agent` interface and `agent/*` events; the goal domain does not import or modify `dsh-agent-loop`. + +## Testing + +Unit coverage pins creation defaults, exact-live-agent checks, compare-and-set rejection, every lifecycle transition, blocker reason validation and retention, cap enforcement on resume, clear/replacement, seeded replay and `SessionStore.fork()` inheritance, session-start and lifecycle-owner disarming, active-goal rearming, FIFO deferred mutation reconciliation, reentrant append observation, rejected-injection rollback, stable corrupt-event replay, service/listener disposal, listener containment, backward-clock clamping, strict record decoding, lifecycle continuity, source/content agreement, and sequential round attribution. A keyless Loader/stdio process test mounts the service and a lifecycle consumer through test-only `cordis.yml`, then reads the persisted JSONL externally to verify the model-visible snapshot and absence of an unrequested goal round. The package source is held to the repository's per-file 100% coverage gate. + +## Alternatives considered + +- **Store goals in a separate database or session header** — rejected because the session log already supplies ordering, persistence, fork prefixes, and reconstructability; a second store introduces atomicity and lineage questions. +- **Use hidden log-only events** — rejected because durable state that changes future model behavior must be model-visible and reconstructable under the repository's logging invariant. +- **Persist activation and restart automatically** — rejected because opening or resuming a session must wait for human input; durable phase records status, not fresh authority to spend resources. +- **Count all session turns as goal rounds** — rejected because one session can contain human clarification, inspection, and unrelated work; only goal-attributed continuation turns consume this budget. +- **Add goal state or a generic loop abstraction to `dsh-agent-loop`** — rejected because state and continuation policy can compose through existing plugins, `Agent` verbs, and events without privileging the shipped loop implementation. + +## Consequences + +- Goal history survives persistence, resume, compaction of unrelated nodes, and session fork as ordinary session data. +- Resume and fork expose the same durable phase while remaining operationally inert until an explicit resume mutation arms activation. +- Full snapshots simplify inspection and strict replay but repeat the objective and state fields in model history until compaction shadows them. +- Revision and lifecycle validation reject tampered, partially written, or producer-inconsistent goal records early. +- Round caps bound continuation count only; policy consumers map round, token, currency, time, and provider limits to blocked reasons when they stop work. + +## Known limitations and deferred work + +- This domain records state but does not schedule goal rounds, cancel active turns, or classify abnormal stops. +- The actor that records `complete` or `blocked` is authoritative; an independent evaluator or completion certificate is deferred to a policy consumer. +- There is one current goal per session; parallel objective graphs and cross-session goal storage are absent. +- Plugins share one trusted process boundary.

Keeping command names, help text, autocomplete, dispatch, and cancellation inside each adapter makes every new command an adapter edit, prevents optional plugins from contributing commands, and lets the two front doors drift. Treating slash input as an ordinary model prompt is also unsafe: a user-visible direct action can unexpectedly consume tokens or let the model reinterpret an unknown command. + +A shared mechanism must remain a UI concern rather than a model tool or agent-loop branch. It also needs exact per-agent visibility, HMR-safe removal, per-session ACP discovery, direct result rendering, and request-scoped cancellation without adding command text or output to model history. + +## Decision + +`@deepseek-ai/dsh-commands` in `packages/ui/commands/` is the product command registry. The terminal and ACP app bundles mount it beside their consuming front door, and the SDK project helper emits the same service when scaffolding ACP directly; the executor-less, UI-less agent spine remains independent. TUI and ACP inject the service, while command producers depend only on the registry and any domain they operate. + +### Registry contract + +A `CommandDefinition` contains a lowercase name without `/`, a non-empty description, an optional unstructured-input hint, and an abortable handler. Registration validates and detaches the metadata, freezes the effective definition, and returns the exact Cordis effect disposer. Duplicate names fail within one layer. Every adapter consuming the registry sees every effective definition; a command plugin that cannot operate in a deployment omits its registration there instead of encoding adapter identities in the shared domain. + +`list(agent)` returns immutable name-sorted descriptors after scoped shadowing. `find(agent, name)` resolves the effective definition. `execute(agent, line, signal)` parses and runs a known definition, returning a detached `success` or `error` result; invalid syntax and unknown names return `undefined` so the adapter owns its direct error text. + +`parseCommand(line)` requires `/` at byte zero, a lowercase ASCII name containing letters, digits, `_`, or `-`, then whitespace or end-of-input. It preserves the complete adapter-delivered suffix as `rawInput`, including separator whitespace. Command-specific plugins own every further grammar decision. + +### Scope and lifecycle + +An unscoped registration is global. A command-injected plugin mounted beneath an agent context inherits that agent's scope key and lifetime, so its definition shadows a same-named global only for that exact agent. The child declares its own `commands` injection because `agent.ctx` intentionally inherits the core agent-loop dependency surface; adding a UI service to the loop merely to enable scoped registration would invert the dependency graph. + +Registration and removal emit the unfiltered, non-vetoing `commands/change` registry notification. Adapters recompute each live agent's effective view rather than trying to infer which sessions a change affects. The registry contains and logs each observer failure independently, so a broken UI refresh cannot roll back another plugin's mutation or starve a later observer. Cordis ownership removes definitions when their producer, UI instance, or agent scope unloads, so HMR cannot leave stale discovery entries or handlers. + +### Direct dispatch and cancellation + +Commands run in a human-only command plane. Their input does not become `user/message`, their output does not become a session event, and neither is sent to the model. A handler receives the exact target agent, raw input, and request-owned `AbortSignal`. The registry stops awaiting an uncooperative handler when the signal aborts; the handler remains responsible for stopping external side effects already started. + +Expected handler failures return `CommandResult.error`. Thrown or malformed results remain adapter-visible command failures, not model messages. This boundary deliberately separates UI output from durable domain mutation: a goal command may change `ctx.goals`, for example, but the goal service owns that persisted state. + +### TUI mapping + +The TUI registers `help`, `clear`, `cancel`, `reasoning`, `tools`, `redraw`, and `exit` as agent-scoped command definitions instead of switching on strings. Its autocomplete and help view read the live catalog, so plugin commands appear and disappear with their effects. Any submitted line beginning with `/` stays in the command plane; unknown input produces a terminal warning rather than falling through to `Agent.send()` or `Agent.steer()`. + +Each submitted command owns an `AbortController`. TUI disposal aborts outstanding dispatches, removes the local definitions, and waits for the command-producing fiber before completing teardown. + +### ACP mapping + +The bridge follows the current [ACP v1 slash-command contract](https://agentclientprotocol.com/protocol/v1/slash-commands). `session/new` and `session/load` emit the exact agent's full `available_commands_update` snapshot; a new session's RPC response introduces its server-generated id before the snapshot is enqueued. Every registry change emits a replacement snapshot for each live session. Names, descriptions, and optional unstructured-input hints map directly to `AvailableCommand`. + +ACP permits a command prompt to contain additional supported content blocks. The bridge applies its ordinary lossless `text` and `resource_link` flattening, then enters the command plane when the result starts with `/`. Unsupported prompt blocks are rejected by the existing capability boundary. Known commands execute directly; unknown or malformed slash input returns a direct error and never reaches the model. Successful text, expected errors, and thrown-failure diagnostics stream as live `agent_message_chunk` output and settle `end_turn`. + +One model prompt or direct command may be in flight per ACP session, independently across sessions. `session/cancel` aborts the direct command when one owns the request; it calls `Agent.cancel()` only for an agent prompt, so cancelling a command cannot destroy unrelated queued or injected agent work. Connection teardown aborts commands and then disposes the owned agents. + +## Testing + +The registry suite covers syntax boundaries, immutable normalization, runtime metadata validation, deterministic sorting, global and scoped shadowing, duplicate rejection, exact disposal, contained change-notification failures, direct invocation, expected and malformed results, synchronous and asynchronous failure, and every abort timing edge at per-file 100% statement, branch, function, and line coverage. + +TUI tests exercise all migrated built-ins, live plugin discovery, help/autocomplete refresh, direct results, unknown-command rejection, raw-input delivery, definition removal, startup rollback, and disposal cancellation. ACP tests use the real SDK connection, agent factory, loop, and JSONL persistence to verify create/load snapshots, dynamic updates, scoped multi-session catalogs, supported-block flattening, direct success/error/failure, unknown-command isolation, cancellation, and the absence of model requests or session messages.

A continuation driver must bridge active goal state to the ordinary agent loop without adding goal-specific branches to `dsh-agent-loop`, inventing a second conversation, or treating every human turn as an autonomous iteration. + +That bridge has concurrency and durability obligations. Human input, cancellation, a goal edit, persistence failure, session restart, plugin unload, and a downstream prompt policy can all race a pending continuation. A naive `goal/changed -> agent.send()` listener can admit obsolete work, run alongside a human prompt, spend beyond the cap, or restart from replay without new authority. + +## Decision + +`@deepseek-ai/dsh-goal-session` in `packages/goal/goal-session/` is a policy plugin over `ctx.goals`, the public `Agent` interface, and durable session events. It imports no concrete agent-loop implementation. For each exact live `Agent`, it owns process-local scheduling state and may reserve at most one automatic round. + +The hierarchy is Goal → Goal Round → Turn → Step. A goal round is the outer continuation policy iteration; it becomes one goal-sourced session turn, and that turn can contain any number of ordinary model/tool steps. Human turns in the same session are not goal rounds and never increment `roundsStarted`. + +The plugin has no configuration. `maxGoalRounds` is resolved and persisted by `dsh-goal`, and the same-condition blocking threshold is resolved and prompted by `dsh-tool-goal`. Repeating those tunables in the driver would create multiple owners for one policy. + +### Reservation and admission + +When an agent is idle, has no competing queued work, and its current goal is `active` plus `armed`, the driver checkpoints pending goal mutations and rechecks every predicate after the await. If `roundsStarted` already equals `maxGoalRounds`, it records `blocked` with code `round-limit`. Otherwise it reserves the exact identity `{ goalId, revision, round: roundsStarted + 1 }` and the complete rendered prompt before calling `Agent.send()` with `GoalMessageSource`. The prompt JSON-quotes the objective so multiline or tag-like text remains an unambiguous data value inside the familiar frame. + +The `agent/prompt-submit` waterfall is the admission fence. A positive goal source is allowed only when it exactly matches the driver's pending identity and content, the live goal still has that id and revision, activation remains armed, and the round is still the next number. The plugin checks once before delegating and again after downstream hooks return. This second check prevents an async hook from editing or pausing the goal while still admitting the old prompt. + +Only the resulting `user/message` is an admitted round and advances the goal fold. A stale reservation becomes a durable `prompt/blocked` plus zero-step rejected turn, but the driver marks it stale and does not charge the round. A downstream policy rejection that is not caused by staleness blocks the goal rather than retrying around policy. + +### Human work and revision races + +`agent/queued` distinguishes the driver's complete accepted record from every other prompt. Ordinary work already queued before a reservation prevents scheduling. Ordinary work queued while an automatic prompt is pending makes that reservation stale, so a mixed batch admits the human prompt but rejects the automatic one. Ordinary work arriving after the goal round was admitted remains queued for its own next turn; continuation is reconsidered only when the agent later becomes idle. + +A goal mutation during a round advances its durable revision. Settlement of the older revision cannot overwrite that mutation. The driver discards the old attempt outcome, reads the new projection, and continues only if the new revision is still active and armed. This makes model-recorded completion, pause, block, and edit authoritative over the physical turn's later close reason. + +### Settlement + +The driver classifies one closed goal-owned turn as follows: + +| Turn result | Action | +|---|---| +| durable `completed` | continue while active/armed and under cap | +| cancellation of a reserved/admitted goal round, or its `aborted` result | pause and disarm | +| `error` with code `RATE_LIMIT` or `QUOTA` | block with code `usage-limited` | +| other `error` | block with code `turn-error` | +| `max-tokens` | block with code `max-tokens` | +| non-stale `rejected` | block with code `prompt-rejected` | +| failed durability checkpoint | disarm without changing durable phase | +| `disposed` or `interrupted` | disarm | +| plugin-added unknown result | block for inspection | + +No abnormal outcome requests an automatic retry. A later human prompt can ask to continue in any language; the model reads the stopped goal and uses the goal tool's resume action, which records a new revision and arms continuation. + +### Durability and cancellation seam + +Every `goal/changed` notification creates a checkpoint obligation. The driver awaits `ctx.sessions.flush(session)` before reserving work, then checks for a newer mutation, agent lifecycle change, or competing prompt. Turn-end flush failure is reported by the existing `agent/error` notification after `turn/end`; the driver finds that exact closed turn even when a concurrent one-shot injection appended a later turn, associates the failure with the exact attempt, and disarms before the next idle decision. + +Broad cancellation previously exposed only its effects after queues were cleared or the request aborted. The public agent vocabulary now includes observe-only `agent/cancel-requested(agent, reason)`. The concrete loop emits it for effective cancellation before either action; fused notification containment means a broken listener cannot veto cancellation. The goal driver uses this edge to clear its reservation before the loop destroys the queued-work evidence. When that reservation is a queued or admitted goal attempt, cancellation durably pauses the goal; when cancellation belongs to unrelated human work with no goal attempt, it only removes process-local activation. If the pause mutation throws, the driver falls back to disarming rather than allowing cancelled automatic work to restart. + +This is a coordination notification, not a second stop API. `Agent.cancel()` remains the only public broad cancellation verb, idle calls remain no-ops, and custom `Agent` implementations that claim the interface must honor the event ordering if consumers depend on it. + +### Process lifecycle + +`GoalService.disarm(agent)` removes only process-local activation. It writes no session event, changes no revision, and emits no goal mutation. The driver calls it while loading over existing agents, on durability uncertainty, and before teardown; a later `resume` is the durable activation edge visible to the model. + +The driver's event listeners and quiescent close are nested in one ordered Cordis effect. Cordis unloads sibling effects concurrently, so separate listener and cleanup registrations could remove the prompt fence while an async disposer was still draining. The composite effect first closes admission, disarms goals, cancels an admitted attempt, and awaits both agent and driver quiescence; only then does it unregister its listeners. + +An inbox acceptance can win the microtask race immediately before plugin unload begins. In that case the turn and even its first request may start and the round remains durably charged; once unload starts, cancellation aborts it, no following round is scheduled, and the goal remains active but disarmed. Pretending that already-observed admission never happened would corrupt replay accounting. + +## Testing + +The unit suite uses the real agent loop and session service with only the model scripted. It covers exact sequential admission and cap enforcement, load/resume inertness, every outcome classification, rate limiting, request errors, max tokens, downstream prompt veto, pre-admission and in-flight cancellation, unrelated-human cancellation, failed-pause fallback, human-input ordering, queued and downstream revision races, forged goal attribution, failed mutation and turn checkpoints including a later one-shot injection, scheduler and custom-agent failures, session-start reset, exact lifecycle retirement, and queued/running plugin teardown. The new driver source has per-file 100% statement, branch, function, and line coverage. + +A keyless ACP snapshot mounts the shipped editor app with the real goal domain, goal tools, goal driver, agent loop, persistence, and replay adapter through `cordis.yml`. One human turn creates and inspects a two-round goal, the first automatic turn stops normally, and ACP cancellation of a deliberately stalled second round records a durable pause. The normalized wire transcript and external JSONL assertions prove one session, round sources `1, 2`, the lifecycle mutation, and exact replay accounting without using `echo-agent` as an application surrogate. + +The core cancellation test proves notification order and containment: observers run only for effective cancellation, can queue replacement work before the inbox clear, cannot veto later observers by throwing, and an idle call emits nothing. + +## Alternatives considered + +- **Add a goal loop inside `dsh-agent-loop`** — rejected because the public queue, prompt, session, cancellation, and status seams are sufficient, and a concrete-loop branch would privilege one policy. +- **Use `agent/turn-continuation` to make every round another step** — rejected because a goal round is an outer policy iteration and must have its own durable user prompt, turn boundary, round count, and failure settlement. +- **Persist a pending reservation** — rejected because a crash cannot prove that queued process memory had reached admission; only the durable `user/message` consumes the round. +- **Retry provider or persistence errors automatically** — rejected because retry policy spends resources and needs explicit authority; stopped phases plus later human resume are simpler and observable. +- **Fork conversation history or spawn a fresh agent for every round** — rejected for this package because the goal is explicitly same-session work. Fresh-agent Ralph execution remains a separate workflow plugin built from subagent and workflow primitives. +- **Reuse every session turn as the round counter** — rejected because human clarification and unrelated work share the session but not the automatic-work budget. + +## Consequences + +- Goal continuation remains a removable plugin and the concrete loop gains only a generic observe-before-cancel notification. +- Replay can reconstruct every admitted round from its exact goal source and prompt; rejected reservations cannot create phantom budget use. +- Human messages and lifecycle mutations win documented races without corrupting the revision or counter. +- Resume and fork remain inert until semantic human intent causes the model to record a resume mutation. +- Conservative failure mapping can require manual continuation after transient failures, but it never hides an automatic retry. + +## Known limitations and deferred work + +- Completion evidence and semantic blocker equivalence remain model judgments.

The cheapest implementation can derive one from the first prompt, while higher-quality implementations may call a model over the first prompt or the whole conversation. Those strategies have different latency, cost, routing, and retry behavior, but every consumer needs one durable source of truth. + +Session identity metadata is immutable, the event log is the replay and fork boundary, and every event must remain turn-enclosed. A model-generated title often finishes after the main turn closes, so writing it synchronously would delay the agent response while writing it as mutable metadata would bypass ordinary persistence, replay, and lineage semantics. Concurrent prompts, provider HMR, cancellation, and ignored abort signals also make an unfenced background result capable of overwriting a newer title. + +## Decision + +The [`session-title` capability family](../../../../packages/session-title/README.md) owns title state and generation policy. `@deepseek-ai/dsh-session-title` provides `ctx.sessionTitle`, a deterministic first-message fallback, and a registry for at most one optional asynchronous provider. `@deepseek-ai/dsh-session-title-llm` owns the common auxiliary-model request policy; separate first-message and all-user-messages plugins choose input cadence. The shared agent spine mounts only the fallback service with overridable explicit example limits, leaving both model providers opt-in. + +### Event ownership and folding + +Every accepted revision is a log-only `session/title` event. Its payload contains normalized non-empty text, the exact eligible human `user/message` seqs used to derive it, and either fallback provenance or the registered provider id plus optional provider/model route. Before an auxiliary title-model dispatch, the shared helper appends a log-only `session/title-llm-request` event containing the title-provider id, exact source seqs, route, system prompt, messages, and output-token cap; a later generation failure leaves the request auditable. The dispatched envelope is deep-frozen to preserve exact agreement with that record but carries no process-local agent-loop request identity, so loop-only reconstruction checks do not compare it with the main conversation header. Validation failures that never reach dispatch create no request event. `foldSessionTitle()` selects the latest title event and adds that event's seq and timestamp as `SessionTitleSnapshot`. Neither event enters `session.surface` or `deriveMessages()`. + +The core session package exposes `ctx.sessions.appendOutOfBand()` only for plugin event types whose owners also declaration-merge an `OutOfBandSessionEventMap` marker. An open turn receives the log-only event directly and owns its normal checkpoint. A closed log receives `turn/start → event → turn/end` under the plugin's trigger, followed by an awaited flush. Once the synthetic turn opens, target-append failure still attempts to close and flush it; detach is deferred until the sequence settles. Session titles contribute the source-free `session-title` zero-step trigger and opt both title event types into this seam. No message caused that trigger, so consumers of the merge-extensible `TurnTriggerMap` discriminate `kind` before reading variant fields; goal-round admission, for example, ignores every non-`message` trigger. + +### Input and asynchronous timing + +Only text blocks from human-source `user/message` events are eligible. Empty, control-only, and non-text prompts wait for the next eligible message. The service schedules the first fallback without awaiting it from the prompt path, normalizes whitespace and control sequences, applies the configured word and UTF-8 byte limits without splitting a code point, and records the first message seq. + +Automatic provider work starts only after the main loop has a current logged provider/model route. A newly appended `request/header` starts pending work directly; when the header is unchanged, the marked loop-built `llm/stream` request starts it after matching the folded route. Generation then runs independently of the agent response, and a completion joins whichever turn is open at acceptance time or uses the zero-step append path. Explicit `refresh(session, signal?)` materializes any missing fallback and awaits the registered provider; without a provider it returns the fallback. Caller cancellation during fallback flush does not roll back the durable append, but `refresh()` rechecks the signal and rejects instead of returning success. Concurrent refreshes reserve their session-local revision before waiting for fallback durability, so a newer call supersedes an older call before either can invert provider completion order. Automatic work and concurrent refreshes share one session-local in-flight fallback promise, so the first fallback creates only one title event and zero-step turn. All title-capability out-of-band writes share a per-session settlement queue; a replacement model request waits for any earlier title write, while the superseded model call itself remains independently abortable and cannot commit stale output. A title accepted during asynchronous compaction remains log-only, so the compactor's post-summary surface-node check tolerates it; a concurrent surface mutation still invalidates the replacement. + +The first-message provider schedules once when a fresh session first creates its fallback. An automatic failure does not reschedule on later prompts; `refresh()` is the retry path. The all-messages provider schedules after every eligible human prompt and passes all eligible messages through that revision, including seeded history. Its newer revision aborts and supersedes older pending or active work. + +### Registration, routing, and failure policy + +`register(provider)` validates one branded stable id, cadence, and generation function, then returns an awaitable effect disposer. A second live registration throws immediately. Provider disposal marks the registration closing, aborts its pending and active work, and waits for every call to settle before removing the registration, so replacement cannot overlap a provider that ignores cancellation. Session disposal aborts its active work. Service teardown prevents queued fallback and provider microtasks from starting, aborts active work, and drains tracked promises before unloading completes. Every session-local generation has a monotonic revision and exact registration identity; acceptance rechecks revision, registration, session liveness, service liveness, and cancellation, so stale output cannot commit. + +Model providers require explicit word, CJK-character, input-byte, output-token, and timeout limits. Optional `provider` and `model` overrides are a pair; without them the helper uses the exact route from the logged main request header. Selected messages are framed as JSON under one fixed language-aware instruction. The input limit measures that final user prompt, including wrappers, seq fields, and JSON escaping, before the request is logged or dispatched. Oversized input is rejected rather than truncated because truncation would make the recorded source seqs falsely imply complete use. The fused deadline is checked while consuming each stream chunk and after completion, so a successful result returned after timeout cannot be accepted even when an interceptor or adapter ignores abort. + +Automatic provider failures are nonfatal warnings and retain the latest title. Explicit refresh failures reject to the caller. Output must be non-empty text with unique ordered seqs drawn from the fixed request; the service normalizes and byte-limits it before durable acceptance. + +### Forks and consumers + +A fork inherits seed title events unchanged, like the rest of its source log. The first-message provider does not automatically retitle a fork. The all-messages provider may append a child-owned revision after a later child prompt, using inherited and new eligible messages. + +`ctx.sessionQuery.readTitle()` folds one live-preferred or persisted log without loading titles during `listSessions()`. ACP maps the event to `session_info_update` during both live streaming and load replay, using the event timestamp for `updatedAt`. The TUI uses the latest title as its header subtitle and sets the terminal window title to ` — ` after terminal-safe rendering. A synthetic title turn remains a completed durability boundary for the metadata write; consumers reporting agent completion use the core `findLastMessageTurnEnd()` fold so a later title, injection, or other plugin-owned turn cannot replace the preceding message-triggered outcome. + +## Alternatives considered + +- **Mutable `SessionHeader` or side metadata** — rejected because it creates a second persistence mutation protocol, weakens immutable identity metadata, makes crash atomicity backend-specific, and gives forks ambiguous copy-versus-reference behavior. The append-only log already owns replayable latest-wins state. +- **Await title generation before returning the agent response** — rejected because auxiliary provider latency and failure would sit on the main interaction's critical path. The deterministic fallback gives immediate useful state while a better title may arrive later. +- **Put titles in derived history or the request prefix** — rejected because UI metadata would consume tokens, change cache identity, and make the main model observe its own label. A log-only event remains reconstructable without becoming model-visible. +- **Permit multiple registered providers and resolve precedence after completion** — rejected because completion order is not product precedence and would make retries, HMR, and provenance nondeterministic. A deployment that needs a composite policy can register one provider that owns that policy. +- **Silently truncate oversized auxiliary input** — rejected because the provider result would claim exact source-message provenance while receiving only partial text. Keeping the prior title and warning preserves truthful attribution. +- **Index titles in `listSessions()` immediately** — rejected because the existing lightweight metadata list would need per-backend derived-index synchronization. Exact `readTitle()` establishes the read contract without precommitting search or indexing policy. + +## Consequences + +- Titles survive JSONL and SQLite persistence, replay through ACP, and follow fork inheritance without a separate mutable record. +- A fallback appears without an auxiliary call; deployments choose whether better titles justify model cost and whether later prompts should retitle a session. +- Auxiliary request records and late accepted titles consume event seqs and may create balanced zero-step turns, so persistence exposes both attempted dispatches and accepted updates even though model history and KV-cache identity do not change. +- One provider and monotonic per-session revisions make disposal, supersession, and stale-result rejection explicit, at the cost of leaving multi-strategy precedence to a composite provider. +- Manual rename, deletion, generated-versus-user precedence, search, and list indexing remain outside the capability. diff --git

The loop's own stop paths (`cancel()` and disposal) abort the current `AbortController` directly rather than routing through `Agent.abort()`. Most tests that called `abort()` interrupt an empty queue and switch to `cancel(reason)`; the steering re-delivery test that deliberately depends on queue preservation drives the in-flight `AbortController` directly, because `cancel()` would drop the queued steering it is trying to prove survives a step abort. The no-argument `abort()` default reason (`'aborted'`) is deleted with the verb rather than preserved by accident; `cancel()` keeps its own `'cancelled'` default. +The behavioral distinction is real, but no shipping code needs the narrower operation. AgentLoop instead owns one private cancellation holder for the whole turn. `cancel(cause?)` carries a typed `user` or `parent` cause, defaults to `user`, and drops pending input; disposal remains a separate lifecycle interruption. The complete ownership and propagation contract lives in the [explicit turn cancellation RFC](../architecture/2026-07-16-explicit-turn-cancellation.md). The extra surface area made the loop carry a public verb that is mostly a teardown internal: `abort()` had to be documented as distinct from queue-aware cancellation even though a UI cancellation almost always wants the broader operation. ## Decision -`cancel()` is the only public *stop* primitive on `Agent`.

Its live consumers are ACP and agent tests that await settlement through this public seam (`packages/ui/acp/tests`, `packages/core/agent-loop/tests`); the production ACP bridge owns its agents and tears them down through `AgentHandle.dispose()`, so `packages/ui/acp/src` itself has no `whenIdle()` call. -Public `abort()` is deleted, with the tests that exercised it as standalone API and the docs that described step-only abort as an embedding feature.

A tool can therefore satisfy its own type while accidentally dropping cancellation at the next same-process call. + +That gap is transitive.

It also excludes work after an explicit detached-ownership handoff: once a task, workflow, worker, or child agent has been successfully published to a new lifecycle owner, that owner's controller governs the detached lifetime. The initiating start operation still requires the caller signal until the handoff commits, and any later tool call that waits for detached work requires its own invocation signal. + +Optional cancellation may remain on parser, config, model/tool JSON, durable/file format, worker, process, or wire inputs when the external protocol makes it optional. The owning boundary must resolve that input into a required same-process signal before calling a migrated capability seam. + +## Alternatives considered + +**Leave downstream signals optional because tool bodies now receive one.** Rejected because availability at the outer callback does not make propagation type-safe; omission remains legal at every optional capability call. + +**Enforce propagation with lint rules or callback inspection.** Rejected because syntax checks cannot reliably identify ownership, derived signals, abstraction layers, or correct quiescent settlement.

Migrate by coherent capability family and use typecheck failures as the complete caller inventory. + +**Incorrect detached-work classification.** Excluding a start operation too early can detach work before publication is committed; requiring the parent signal forever can let a completed tool cancel legitimately detached work. Each handoff needs an explicit commit point, new owner, rollback behavior, and quiescent failure path. + +**Signal ownership confusion.** A capability that stores a borrowed signal beyond the delegated lifetime can bind work to a stale caller.

Fork, resume, transcript rendering, telemetry, and persistence derive from the same stream. -**Model-visible ⟺ logged**: the log reconstructs every request — messages at `step/start` fronted by the header's session prefix, headers by folding `request/header` — and dev invariants assert this ([reconstructability](../.agents/notes/implemented/architecture/2026-07-05-reconstructable-requests.md)). +**Model-visible ⟺ logged**: the log reconstructs every request — messages at `step/start` fronted by the header's session prefix, and headers by folding `request/header` — and the package-owned `dsh-agent-loop/invariant` can assert it through `ctx.invariants` ([reconstructability](../.agents/notes/implemented/architecture/2026-07-05-reconstructable-requests.md)). Durability is a plugin concern. Backends buffer synchronous `session/event` notifications; the loop awaits a turn-end checkpoint. `SessionPersistence` stores `SessionEvent` directly and metadata in `SessionHeader`; JSONL defaults to checksummed Zstandard, with SQLite under one contract. +`ctx.sessions.appendOutOfBand()` joins plugin-owned log-only events to an open turn or creates a balanced, flushed zero-step turn. `session/title` folds latest-wins with source seqs and provenance; its immediate fallback and sole optional async provider never delay the agent response. Forks inherit titles ([decision](../.agents/notes/implemented/feature/2026-07-21-log-backed-session-titles.md)). + ### Model Content -Messages contain typed blocks (`text`, `reasoning`, `tool-call`, `tool-result`) derived from merge-extensible `ContentBlockMap`; the same pattern types `MessageSource`, `FinishReason`, `TurnTrigger`, and `TurnEndReason`. New block types coordinate adapters, UI bridges, compaction pricing, token metering, and persistence as one repo-wide contract; replay measurement types live in [token-meter.md](core-data-structures/token-meter.md). +Messages use typed blocks from merge-extensible `ContentBlockMap`; the same pattern types `MessageSource`, `FinishReason`, `TurnTrigger`, and `TurnEndReason`. New blocks coordinate adapters, UI, compaction, token metering, and persistence; replay measurements live in [token-meter.md](core-data-structures/token-meter.md). -Streaming uses raw chunks (`block-start` through `finish`) and `BlockAssembler`. The loop logs and assembles chunks, storing provider/model provenance plus replay state. An `LlmAdapter` implements `stream()`, registers provider routes, and may expose selector metadata; it resolves and validates model ids. Replay state reaches targets only when both routes map to one adapter instance, which owns validation and conversion. The contract lives in [llm-streaming.md](core-data-structures/llm-streaming.md). +Streaming uses raw chunks and `BlockAssembler`. Each `LlmAdapter.stream()` is one provider attempt; adapters report facts and `agent/request-error` owns recovery. The loop logs chunks and successful provenance/replay state. Remote adapters use per-read idle watchdogs. Replay state crosses routes only when they share an adapter instance ([contract](core-data-structures/llm-streaming.md)). ## Extension And Composition ### Capability Pattern -A swappable capability usually splits into **interface / implementation / consumer**: the interface owns its `ctx` key and events, an implementation registers a backend, and a consumer exposes model behavior through tools or prompts. Bash is the reference; the [capability graph](capability-seams.md) shows every family. +A swappable capability usually splits into **interface / implementation / consumer**: service/events, a backend, and model-facing tools/prompts. Bash is the reference; the [capability graph](capability-seams.md) maps each family. -Some seams bend the template deliberately: LLM combines interface and consumer because adapters implement it; filesystem wraps provider primitives with policy; web keeps search/fetch provider registries behind one service; skills and subagents use named providers. Subagents spawn fresh, fork a completed-turn prefix, or use ACP children ([subagent.md](core-data-structures/subagent.md)). +Exceptions combine layers: LLM interface/consumer; filesystem policy; web registries; named skill/subagent providers. Subagents spawn fresh, fork a completed-turn prefix, or use ACP children ([subagent.md](core-data-structures/subagent.md)). `dsh-workspace-context` composes baselines on `agent/session-prefix` and appends `ctx.fs`-discovered nested changes on `tools/post-execute`; its [decision](../.agents/notes/implemented/feature/2026-06-24-workspace-context.md) records isolation. `dsh-paths` owns shared paths. ### Bundles And Apps -`dsh-agent-spine-demo` bundles the default spine ([README](../packages/examples/agent-spine-demo/README.md)). `dsh-stdio-demo` selects `dsh-tui` for interactive terminals and line-oriented `dsh-stdio` for pipes; `dsh-cli-demo` runs one persisted headless turn with format-pure stdout; `dsh-acp-demo` adds stdout-pure ACP over JSON-RPC ([ui/](../packages/ui/README.md)). `dsh-jsonrpc-agent` boots external `cordis.yml`; the Python SDK supplies its default only without an explicit config channel and drives `dsh-jsonrpc` over line-delimited JSON-RPC ([Python SDK](../python/README.md)). Deployments remain thin leaves with swappable backends and optional product tools ([examples/](../examples/AGENTS.md), [runnable wirings](cookbook/extension-cookbook.md#runnable-wirings), [graph atlas](graph-atlas.md)). +`dsh-agent-spine-demo` bundles a spine and optional goals. App packages own the TUI, one-shot CLI, and ACP/JSON-RPC front doors ([README](../packages/examples/agent-spine-demo/README.md), [ui/](../packages/ui/README.md)). `dsh-jsonrpc-agent` boots external `cordis.yml`; the Python SDK supplies a default only without explicit config ([Python SDK](../python/README.md)).

`additionalContexts`，会在结果产生后稳定。steering（中途引导）会在 `agent/post-step` 前排空；该事件会观察持久输出、结果、上下文和 steering。余留内容进入队列。终止型 `agent/turn-stop` 在关闭和刷写期间始终具有最终决定权；后续 steering 会被丢弃，排队提示词仍予保留。 +

`agent/error`。取消和资源释放均优先于恢复；尚未分派的工具调用会得到合成的 `tool/call`/`ABORTED_BEFORE_DISPATCH` 对。轮次信号会在 `turn/end` 前失效。实际生效的 `cancel()` 会在清空队列和中止前发出类型化原因；观察方不能否决该操作，空闲状态下的调用不发出任何事件，持久化会记录 `aborted`。dispose（资源释放）会等待系统停稳（[决策](../.agents/notes/implemented/architecture/2026-07-16-explicit-turn-cancellation.md)）。 + +每个会话事件都包围在轮次内。重新加载会保留中断的日志尾部，并用合成的 `interrupted` 轮次结束事件将其闭合。持久轮次关闭后的故障只通过

在发布前完成组合。类型化解析器从合并后的 `Events` 和 `scopeTarget` 推导载体检查（[语义门禁](../.agents/notes/implemented/process/2026-07-14-typescript-program-backed-semantic-gates.md)）。参见 [agent

`request/header` 得到的请求头；开发期不变量会断言这一点（[可重建性](../.agents/notes/implemented/architecture/2026-07-05-reconstructable-requests.md)）。 + +持久性由插件负责。后端会缓冲同步的 `session/event` 通知；循环等待轮次结束检查点。`SessionPersistence` 直接存储 `SessionEvent`，并将元数据存入 `SessionHeader`；JSONL 默认采用带校验和的 Zstandard，SQLite 则遵循同一契约。 + +`ctx.sessions.appendOutOfBand()` 会把插件所属的纯日志事件加入开放轮次，或创建一个平衡且已刷写的零步骤轮次。`session/title` 按后写覆盖方式折叠，并携带源 seq 和来源信息；其即时回退标题和唯一可选异步提供方都不会延迟 agent 响应。fork 会继承标题（[决策](../.agents/notes/implemented/feature/2026-07-21-log-backed-session-titles.md)）。 + +### 模型内容 + +消息使用从可合并扩展的 `ContentBlockMap` 派生的类型化块；`MessageSource`、`FinishReason`、`TurnTrigger` 和 `TurnEndReason` 也采用同一模式定义类型。新增块会协调适配器、UI、压缩、token 计量和持久化；回放计量见 [token-meter.md](core-data-structures/token-meter.md)。 + +流式输出使用原始分片和 `BlockAssembler`。每次 `LlmAdapter.stream()` 调用代表一次提供方尝试；适配器报告事实，`agent/request-error`

**restriction / scope-local registration** — a restriction (`tools.restrict`) filters the GLOBAL tool surface for one scope (compose by intersection); scope-local registrations are merged after that filter. A filtered-away global tool is absent from the prompt AND refuses execution, indistinguishably from a nonexistent one. - **setup window** — the creation slot where a creator composes an agent's scoped world (`CreateAgentOptions.setup`): after the scope and agent object exist but before the agent or session is published, `agent/session-start` fires, or the first prompt is assembled. Setup registers; it never drives the agent. - **lineage** — parent/child facts carried as data (`parentSession`, durable `delegationDepth`, runtime `subagentDepth`); never affects visibility. + +## goal + +- **goal** — one durable completion objective attached to an existing session, with a revisioned `active` / `paused` / `blocked` / `complete` phase and a goal-round cap; `blocked` retains a policy code and explanation. A goal is state, not a scheduler or a separate conversation; the session log remains its source of truth. +- **goal round** — one continuation cycle admitted for the current goal. The same-session driver materializes a goal round as one goal-sourced [turn](#turn), which can contain multiple steps; unrelated human turns in the same session do not consume the goal-round cap. +- **goal activation** — process-local permission for a continuation consumer to admit another goal round. Activation is either `armed` or `disarmed`; it is deliberately absent from durable replay, so resume and fork require a later human-authorized resume mutation through `/goal` or the model tool before automatic work. + +## human command + +- **human command** — a slash-prefixed instruction interpreted and executed by a human-facing adapter through `ctx.commands`, without becoming a model message. It is distinct from a model-facing tool and from shell command execution through `ctx.bash`. +- **command plane** — discovery, parsing, dispatch, cancellation, and result rendering owned by UI adapters and command plugins. Command output is UI state unless the handler separately mutates a durable domain. +- **goal command** — the `/goal` human command contributed by `dsh-command-goal`; it observes or mutates the current goal directly while the goal domain owns every durable, model-visible record. + +## loop hierarchy + +- **turn** — one drain of admitted input in a session, ending after the model and its tools stop or a terminal policy intervenes. +- **step** — one model request plus the tool executions caused by its response; a turn contains one or more steps. +- **round** — an outer policy iteration containing a turn, such as a [goal round](#goal-round) or one fresh-agent Ralph attempt. Round counters belong to that policy and do not count every turn in a session. + +## Ralph + +- **Ralph loop** — one foreground fresh-agent workflow run toward an immutable objective. It is a model-facing tool policy composed from workflow and subagent primitives, not a same-session goal, agent-loop mode, scheduler, or generic workflow-script feature. +- **Ralph round** — one fresh child session in a [Ralph loop](#ralph-loop). The child receives no parent or prior-child conversation seed; the shared workspace and one bounded [Ralph handoff](#ralph-handoff) carry cross-round state. +- **Ralph handoff** — the normalized bounded structured report passed from one continuing Ralph round to the next, containing status, summary, evidence, next steps, and blocker text. It supplements the shared workspace rather than replacing it as authority. diff --git a/docs/graph-atlas.md b/docs/graph-atlas.md index d477bd6d62..6050c4a60e 100644 --- a/docs/graph-atlas.md +++

The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.

Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const — no oneOf/pattern/format/numeric bounds) it resolves to the validated object.

Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const — no oneOf/pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const — no oneOf/pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them. The run executes in the foreground: this call returns when the whole script finishes. */ workflow(args: { /** The plain-JS workflow script body (top-level await allowed; NO `export const meta` statement; end with `return `). */ diff --git a/examples/acp-agent/tests/snapshots/code-mode-workspace-context/session.jsonl b/examples/acp-agent/tests/snapshots/code-mode-workspace-context/session.jsonl index 4f72ffa498..32bfa5cd58 100644 --- a/examples/acp-agent/tests/snapshots/code-mode-workspace-context/session.jsonl +++ b/examples/acp-agent/tests/snapshots/code-mode-workspace-context/session.jsonl @@ -1,189 +1,190 @@ {"type":"session","version":0,"id":"65fbb8a6-624c-4d6a-bf5d-a7a7d14f2b49","createdAt":1783921765266,"cwd":"/var/folders/_g/59jgff8x2gqd39f5vy1wnbfc0000gn/T/acp-snap-cwd-uorU26","delegationDepth":0} {"type":"turn/start","seq":0,"time":1783921765269,"data":{"turn":1,"trigger":{"kind":"message","source":{"kind":"user"}}}} {"type":"user/message","seq":1,"time":1783921765269,"data":{"content":[{"type":"text","text":"Using ONE run_code program, call tools.read on nested/task.txt.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const — no oneOf/pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them. The run executes in the foreground: this call returns when the whole script finishes. */ workflow(args: { /** The plain-JS workflow script body (top-level await allowed; NO `export const meta` statement;

An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering. +Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work.

After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked. + Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`). Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls. + +Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out. diff --git a/examples/acp-agent/tests/snapshots/text-turn/tool-schemas.expected.json b/examples/acp-agent/tests/snapshots/text-turn/tool-schemas.expected.json index 151e76201b..52b3c1812e 100644 --- a/examples/acp-agent/tests/snapshots/text-turn/tool-schemas.expected.json +++ b/examples/acp-agent/tests/snapshots/text-turn/tool-schemas.expected.json @@ -45,6 +45,26 @@ ] } }, + { + "name": "create_goal", + "description": "Create one persisted same-session completion goal when the current direct human request is a long-running objective that should continue across autonomous goal rounds.

An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

SDK.\n\nYou are headless-agent, a coding assistant powered by the deepseek-v4-flash model. Your working directory is /tmp/advanced-headless.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's text output as a string. Tool arguments must be JSON-serializable.\n- A FAILED tool call rejects with an `Error` carrying the tool's error text — `try/catch` it to handle and continue.\n- Calls execute sequentially, even under `Promise.all`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ndeclare const tools: {\n /** Execute a bash command (`bash -c`) and return its stdout/stderr.

Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, async execute(args) { … } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'boolean'|'object'|'array', required?: true, description?, enum?, items?, properties? }; a JSON-Schema-style { type: 'object', properties, required: […] } wrapper and type 'integer' are also accepted and normalized. A tool's `execute` MUST return an ARRAY of content blocks, e.g. `return [{ type: 'text', text: someString }]` — never a bare string. Mounts can COMPOSE: one plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically on unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned on unmount) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n cordis_mount(args: {\n /** Body of an async JS function; must `return` the plugin to mount. */\n code: string;\n }): Promise;\n /** Dispose a plugin previously mounted with cordis_mount, by id.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const — no oneOf/pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, async execute(args) { … } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'boolean'|'object'|'array', required?: true, description?, enum?, items?, properties? }; a JSON-Schema-style { type: 'object', properties, required: […] } wrapper and type 'integer' are also accepted and normalized. A tool's `execute` MUST return an ARRAY of content blocks, e.g. `return [{ type: 'text', text: someString }]` — never a bare string. Mounts can COMPOSE: one plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically on unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned on unmount) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"Body of an async JS function; must `return` the plugin to mount."}},"required":["code"]}},{"name":"cordis_unmount","description":"Dispose a plugin previously mounted with cordis_mount, by id.

A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, async execute(args) { … } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'boolean'|'object'|'array', required?: true, description?, enum?, items?, properties? }; a JSON-Schema-style { type: 'object', properties, required: […] } wrapper and type 'integer' are also accepted and normalized. A tool's `execute` MUST return an ARRAY of content blocks, e.g. `return [{ type: 'text', text: someString }]` — never a bare string. Mounts can COMPOSE: one plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically on unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned on unmount) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n cordis_mount(args: {\n /** Body of an async JS function; must `return` the plugin to mount. */\n code: string;\n }): Promise;\n /** Dispose a plugin previously mounted with cordis_mount, by id.

SDK.\n\nYou are headless-agent, a coding assistant powered by the deepseek-v4-flash model. Your working directory is /tmp/advanced-headless.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's text output as a string. Tool arguments must be JSON-serializable.\n- A FAILED tool call rejects with an `Error` carrying the tool's error text — `try/catch` it to handle and continue.\n- Calls execute sequentially, even under `Promise.all`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ndeclare const tools: {\n /** Execute a bash command (`bash -c`) and return its stdout/stderr. Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. */\n bash(args: {\n /** The bash command to execute. */\n command: string;\n /** Clear, concise description of what this command does in active voice, 5-10 words (shown in the UI). Examples: \"ls\" → \"List files in current directory\"; \"git status\" → \"Show working tree status\"; \"npm install\" → \"Install package dependencies\". */\n description: string;\n /** Timeout in milliseconds.

Sections: `services` (every provided ctx service and the plugin fiber that owns it), `plugins` (a flat list of the loaded plugins with their lifecycle states), `tools` (the model-facing tools currently registered, i.e. what you can call), `dynamic` (plugins you mounted via cordis_mount: id, name, state, provided services, awaited services), `api` (method signatures AND argument/return type shapes for every LIVE service — read this before writing plugin code that calls a service), `events` (every harness event with its dispatch mode and exact signature — pick listener targets here).

Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, async execute(args) { … } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'boolean'|'object'|'array', required?: true, description?, enum?, items?, properties? }; a JSON-Schema-style { type: 'object', properties, required: […] } wrapper and type 'integer' are also accepted and normalized. A tool's `execute` MUST return an ARRAY of content blocks, e.g. `return [{ type: 'text', text: someString }]` — never a bare string. Mounts can COMPOSE: one plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically on unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned on unmount) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n cordis_mount(args: {\n /** Body of an async JS function; must `return` the plugin to mount. */\n code: string;\n }): Promise;\n /** Dispose a plugin previously mounted with cordis_mount, by id.

Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, async execute(args) { … } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'boolean'|'object'|'array', required?: true, description?, enum?, items?, properties? }; a JSON-Schema-style { type: 'object', properties, required: […] } wrapper and type 'integer' are also accepted and normalized. A tool's `execute` MUST return an ARRAY of content blocks, e.g. `return [{ type: 'text', text: someString }]` — never a bare string. Mounts can COMPOSE: one plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically on unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned on unmount) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"Body of an async JS function; must `return` the plugin to mount."}},"required":["code"]}},{"name":"cordis_unmount","description":"Dispose a plugin previously mounted with cordis_mount, by id.

persistence, loaded from `cordis.yml`. The sibling [`tui-agent`](../tui-agent/README.md) fixes the same agent composition to the full-screen terminal front door. - -## Run it - -```sh -# repo root .env (gitignored) or exported env: -# DEEPSEEK_API_KEY=sk-… -# DEEPSEEK_BASE_URL=https://… # optional; defaults to the public API -pnpm run demo:repl -``` - -Type a coding task. The agent works through the `read`/`write`/`edit` filesystem tools for ordinary file operations and `bash` (+ the generic `task_output` / `task_list` / `task_kill` for background tasks) for shell commands, searches, and test runs, each in a fresh `bash -c` (the system prompt tells the model to pass `workdir` instead of `cd`). Both the fs tools and bash resolve relative paths against the session workspace. It can also delegate with `subagent`/`subagent_fork` and track multi-step work with `todo_write`. - -The REPL renders reasoning, tool calls/results, and the latest todo list as line-oriented output suitable for terminals and pipes. Use `pnpm run demo:tui` for the interactive Markdown/card interface. - -### Resuming a prior session - -Each run starts a fresh session by default (its event log lands under `./.sessions/`). To **continue** a previous conversation, set `RESUME_SESSION_ID` to that session's id — the `main` agent then rehydrates the persisted log instead of starting fresh, so the model sees the earlier turns as history: - -```sh -RESUME_SESSION_ID= pnpm run demo:repl -``` - -The id is wired through `cordis.yml` (`resumeSessionId: !!js process.env.RESUME_SESSION_ID`); unset, the agent starts a new session. A missing or unreadable id starts no agent and emits `agent-loop/config-start-failed`: the TUI prints the failure and exits nonzero, while readline reports any dropped queued input and allows piped EOF to finish. Unset it or choose an existing session id. - -## Code Mode - -[`code-mode.cordis.yml`](code-mode.cordis.yml) overlays the same tree with the worker-thread runtime and `tools: { mode: code }`. The model receives one `run_code` transport plus a generated TypeScript SDK for the visible tools; only program output returns to model context. Use `mode: both` to expose native calls alongside `run_code`. See the [Code Mode Agent Note](../../.agents/notes/implemented/feature/2026-06-15-code-mode.md) for the execution contract. - -```sh -pnpm run demo:code-mode # this overlay under the REPL (default UI) -pnpm run demo:code-mode acp # the acp-agent example's same-shaped overlay -``` - -Try a task that spans several tool calls, e.g.: - -> Count the lines of every `*.md` file under docs/ and write the three largest to summary.txt. - -and watch the transcript: one `run_code` call, a program looping over tools, and a result the model curated instead of five round-trips of raw tool output. - -## What each leaf entry demonstrates - -This example is a thin leaf `cordis.yml`: it picks the swappable backends, loads one app package, and adds product tools that are intentionally outside the shared spine. The spine (sessions, system-prompt, tools, agents, invariants, `agent-loop`) and the front-door cluster (JSONL persistence, the selected terminal channel, the pre-created `main` agent) live inside the [`@deepseek-ai/dsh-stdio-demo`](../../packages/examples/stdio-demo) app and the [`@deepseek-ai/dsh-agent-spine-demo`](../../packages/examples/agent-spine-demo) bundle it loads; the leaf wires the backends and model-facing optional tools: - -| Entry | Demonstrates | -|---|---| -| `hmr` (`@cordisjs/plugin-hmr`) | the dev/demo edit-reload loop — a **leaf** entry (not baked into the app) because it is Loader-only and needs `node --expose-internals`, which `demo:repl` passes | -| `llm-deepseek` | real `LlmAdapter` via config (`!!js process.env.…` secrets); swap one line to `@deepseek-ai/dsh-llm-pi-ai` for the library-backed twin | -| `bash` (`dsh-bash-local`) | the executor implementation — the swappable half of the bash seam. The model-facing `bash` schema (`tool-bash`) and generic `task_*` controls (`tool-tasks`) come from `dsh-agent-spine-demo`, so only the executor is a leaf choice | -| `stdio-agent` (`@deepseek-ai/dsh-stdio-demo`) | the app bundle: the agent-spine demo + JSONL persistence + the configured terminal channel + a pre-created `main` agent.

Pruning runs only after a compaction trigger qualifies and can avoid the summarization call | -| `subagent`, `subagent-spawn`, `subagent-fork` | the subagent provider registry plus the two in-process backends: a fresh child and a child seeded with the parent's completed-turn prefix | -| `tool-subagent`, `tool-subagent-fork` | two model-facing `dsh-tool-subagent` loads, each bound to a different provider and exposed under a distinct tool name (`subagent`, `subagent_fork`) | -| `workflow-workerthread`, `tool-workflow` | the worker-thread workflow engine and its model-facing `workflow` tool, with child calls routed through the spawn backend | -| `tool-todo` | the model-facing `todo_write` tool; writes the whole task list to the session log and renders as a persistent TUI plan or readline checklist | -| `fs-local`, `fs-policy`, `tool-fs` | the filesystem stack: the local `ctx.fs` provider, the read-before-write/edit policy gate (on the `fs/*` event gate), and the model-facing `read`/`write`/`edit` tools. Relative paths resolve against the session workspace | - -## End-to-end tests (`pnpm run test:e2e`, key-gated) - -- `tests/full-loop.e2e.ts` — the canary: real model runs `echo e2e-ok` through the real bash tool; asserts `tool/call`/`tool/result` session events and the final answer. -- `tests/coding-task.e2e.ts` — the swebench-style smoke: a temp dir holds `add.js` (with `a - b` where `a + b` belongs) and a failing `add.test.js`; the agent must fix the bug and verify. The test re-runs `node add.test.js` ITSELF and inspects the files — agent claims are not trusted. -- `tests/resume.e2e.ts` — durable continuity across processes: run 1 tells the real model a secret code and persists the turn to a temp JSONL root, then the whole context is disposed; run 2 is a fresh context over the same root that RESUMES the session id and asks the model to recall the code. The recall can only come from the rehydrated log. -- `tests/compaction.e2e.ts` — the compaction smoke: a real multi-step bash task runs with a deliberately tiny context window so automatic pruning or summary compaction fires mid-session. It verifies the world: a replayable surface replacement lands, summary brackets are complete when summarization is needed, the surface shrinks, and the agent still produces a correct final answer. -- `tests/todo-write.e2e.ts` — a real model drives the real `todo_write` tool and the test verifies the resulting `todo/write` session event. - -These self-skip without `DEEPSEEK_API_KEY`. `tests/code-mode.e2e.ts` is the with-key Code Mode proof — a real model, a two-tool task, asserting the wire tool list was exactly `[run_code]`, the `tool/code-dispatch` events landed under the parent call, and the curated answer came back. The keyless Loader smokes run in the default e2e gate: `tests/keyless-smoke.e2e.ts` and `tests/code-mode-keyless-smoke.e2e.ts`. diff --git a/examples/repl-agent/code-mode.cordis.yml b/examples/repl-agent/code-mode.cordis.yml deleted file mode 100644 index 8802b510ba..0000000000 --- a/examples/repl-agent/code-mode.cordis.yml +++ /dev/null @@ -1,33 +0,0 @@ -# Code Mode adds `ctx.codeRuntime` and changes the registry to one wire tool, -# `run_code`, plus a generated SDK for bash/read/write/edit/subagent/todo_write. -# `demo:code-mode` selects this overlay; the ACP example has the same UI-specific -# shape.

Post-step pressure therefore includes the actual system prompt, tools, prefix, routing, assistant completion, tool results, buffered context, and steering. +- **Routed policy** — proactive pressure resolves capacity from the adapter that owns the latest durable provider/model route, then scales the default policy plus an optional exact-target override into concrete token budgets. Model discovery remains advisory and is not consulted. - **Model-free pruning** — after pressure or canonical overflow qualifies, the optional [`ctx.toolResultPrune`](../compact-tool-result-prune/README.md) service rewrites oversized tool results before range selection. Compact-basic remeasures through `ctx.tokenMeter`, skips summarization when pressure becomes safe, and otherwise summarizes the pruned surface. Below-pressure post-step checks never prune. - **Retention** — compact the oldest whole surface units while preserving a recent tail and balanced tool-call/result cuts through the [`dsh-compact` boundary helpers](../compact/README.md#tool-pairing-boundaries). Turn boundaries do not protect old steps inside a runaway turn. An open indivisible tail declines until it closes.

A region failure records an error end; the surface remains unchanged unless pruning already landed. Operational post-step failures warn and continue, while overflow-recovery failure preserves the original provider error only when no earlier replacement advanced the surface. Cancellation remains authoritative after any progress. The protected `summarize()` method is the sole subclass hook. A template- or remote-summarizer subclass can override it while pressure, retention, provenance, shrink validation, and shadowed-token accounting stay on `ctx.tokenMeter`. The hook returns the summary blocks together with the call envelope it used (`{ summary, provider, model, maxTokens? }`), which is logged on `compact/summary`. ## Config (`BasicCompactConfig`) -Every setting is optional.

An absolute `retainTokens` budget that is not below its scaled threshold fails on the first resolvable target because that comparison requires model capacity. | Key | Required | Meaning | |---|---|---| -| `thresholdRatio` | no (default `0.8`) | Compact at `floor(contextWindow × ratio)`. | -| `retainTokens` | no (default `floor(contextWindow × 0.16)`) | Recent surface budget kept verbatim; must be below the threshold. | +| `thresholdRatio` | no (default `0.8`) | Compact at `floor(routedContextWindow × ratio)`. | +| `retainRatio` | no (default `0.16`) | Recent surface budget kept verbatim as a fraction of the routed context window; mutually exclusive with `retainTokens`. | +| `retainTokens` | no | Absolute recent surface budget kept verbatim; mutually exclusive with `retainRatio` and must be below the resolved threshold. | | `summarizationProvider` | no (default `''`) | Set together with `summarizationModel`; an empty pair resolves the latest logged request target, then the `AgentOptions` pair. | | `summarizationModel` | no (default `''`) | Set together with `summarizationProvider`; an empty pair resolves the latest logged request target, then the `AgentOptions` pair. | | `maxTokens` | no (default `8192`) | Provider generation cap for the summarization call; may include reasoning tokens. | | `compactionRetries` | no (default `1`) | Extra attempts after the first when pressure remains above threshold. | | `maxOverflowRetries` | no (default `1`) | Maximum retries after canonical context-window overflow; `0` disables recovery only. | +| `modelPolicies` | no (default `[]`) | Exact `{ provider, model, ...partialPolicy }` overrides; matching uses both fields and does not depend on `listModels()`. | | `auto` | no (default `true`) | Register post-step pressure and overflow-recovery listeners.

Only final adapter dispatch/iteration failures and terminal in-band error or aborted finishes enter `agent/request-error`; middleware, result processing, tools, and `agent/post-step` remain ordinary turn failures. Recovery receives the exact live error, immutable provider facts, and immutable prior failures after the failed step closes. A retry rebuilds from the durable log in a new numbered step, success clears the consecutive history, and exhaustion records the structured failure once on `turn/end`. AgentLoop privately owns one cancellation holder whose explicit signal spans prompt policy, assembly, every step, model and tool work, recovery, continuation, and terminal stop; it retires the holder immediately before publishing `turn/end`, while the driver may remain `running` through the durability flush. An effective `cancel()` emits the typed runtime-only `user | parent` cause before clearing pending work and cooperatively aborting the holder; notification failures cannot veto cancellation, work queued by a notification observer is cleared, work queued by a later abort observer belongs to the next turn, and idle cancellation emits nothing. Durable `turn/end` remains coarse `aborted`; undispatched model tool calls receive synthetic `tool/call` and `ABORTED_BEFORE_DISPATCH` result pairs. Disposal wins terminal classification, and work that ignores the signal must settle before quiescence. The [explicit-cancellation decision](../../../.agents/notes/implemented/architecture/2026-07-16-explicit-turn-cancellation.md) owns the lifecycle and race contract. Terminal continuation stops remain authoritative through turn close and durability flush. Within a step, exclusive calls form barriers; parallel-safe calls use a bounded rolling pool and are reclassified before start. Only dispatch/body overlaps.

The signal remains authoritative through terminal policy and is retired immediately before `turn/end` publication, so terminal observers and the following durability flush cannot cancel completed turn work. `agent/pre-step` and `agent/post-step` are serial checkpoints around a step's durable work, while `agent/request-error` is the failed-model-request recovery waterfall: it receives the exact error, normalized failure facts, immutable prior-retried facts, and signal after the failed step closes; a retry opens a new numbered step. `agent/turn-stop` is the terminal serial fold: it runs after ordinary continuation and steering folding, and a returned stop remains in force through turn close and flush so later steering cannot create an extra step or turn. Ordinary queued prompts remain intact. Effective broad cancellation first emits the observe-only `agent/cancel-requested` with its resolved typed cause, then clears queues and aborts; notification failures are contained and cannot veto the stop. The [explicit-cancellation decision](../../../.agents/notes/implemented/architecture/2026-07-16-explicit-turn-cancellation.md) owns signal lifetime; the [agent-scope runtime-design Agent Note](../../../.agents/notes/implemented/architecture/2026-07-12-agent-scope-runtime-design.md#three-execution-boundaries-are-deliberately-one-way) owns scoped dispatch and terminal settlement. `PromptDecision.additionalContexts` is an array so every injected context keeps its own source and metadata. A `ContinuationDecision` reason is narrower: it becomes a `steering/message`, not a `context/message`, and therefore carries only content and source. @@ -54,10 +56,10 @@ Turn and step boundaries and the model token stream are durable `session/event` The handle every plugin programs against: -- `agent.send(content, options?)` — queue one independent FIFO item. If claimed, that item becomes the sole ordinary message in its turn; a claimed FIFO successor waits for that turn's checkpoint to settle. Broad cancellation, disposal, or a pre-start failure may instead drop it without a turn. Content and resolved source become one detached, deeply frozen lossless-JSON record before `agent/queued` and enqueue; invalid data throws synchronously, and caller or notification-listener in-place mutation cannot change the log or model input (`agent/prompt-submit` still rewrites by returning replacement content). The [one-send-one-turn Agent Note](../../../.agents/notes/implemented/simplification/2026-07-17-one-send-one-turn.md) owns the rationale. +- `agent.send(content, options?)` — queue one independent FIFO item. If claimed, that item becomes the sole ordinary message in its turn; a claimed FIFO successor waits for that turn's checkpoint to settle. Broad cancellation, disposal, or a pre-start failure may instead drop it without a turn. Omitting `options.source` attests direct human input as `{ kind: 'user' }` and may authorize policy consumers, so plugins, schedulers, and other non-human producers provide their own source. Content and resolved source become one detached, deeply frozen lossless-JSON record before `agent/queued` and enqueue; invalid data throws synchronously, and caller or notification-listener in-place mutation cannot change the log or model input (`agent/prompt-submit` still rewrites by returning replacement content). The [one-send-one-turn Agent Note](../../../.agents/notes/implemented/simplification/2026-07-17-one-send-one-turn.md) owns the rationale. - `agent.steer(content, options?)` — submit steering while the agent is `running`. An open turn records it at the next steering checkpoint before a request or continuation decision; policy can still stop before another step. After turn close and its checkpoint, remaining steering becomes later queued input unless terminal turn policy, cancellation, or disposal discards it. The method uses the same synchronous snapshot-and-validation boundary as `send` and delegates to `send` when idle - `agent.inject(content, options?)` — accept detached in-session context without running the model; the next request sees its `context/message` with `content` rendered verbatim as a user-role message. `options.meta` persists opaque JSON state without rendering it. While a turn is open it joins that turn, deferring FIFO while the current tool batch executes and draining before turn close if execution is interrupted; while idle it is wrapped in a one-shot `injection` turn and durability checkpoint ([the turn-enclosure invariant](../../../.agents/notes/implemented/architecture/2026-06-15-turn-enclosure-invariant.md)). -- `agent.cancel(reason?)` — cancel ALL pending work: clears the queued + steering FIFOs, aborts the in-flight step, and drops a turn about to start (the pre-step window) so a queued-but-not-started prompt never runs. A UI/ACP `session/cancel` maps to this. The single public stop primitive. Idle with nothing pending → a safe no-op. +- `agent.cancel(cause?)` — cancel ALL pending work: an omitted cause means `{ kind: 'user' }`; TypeScript restricts callers to the `user | parent` union, and an active holder copies its discriminant into a detached frozen signal reason before aborting. An effective call emits `agent/cancel-requested` with the cause before clearing queued and steering work; observers may synchronize state but cannot veto cancellation. The same-process typed seam adds no runtime validation or compatibility fallback for untyped callers. Repeated active-turn cancellation is first-wins for the signal, and idle cancellation is a safe no-op with no notification. ACP maps to `user`, while in-process parent propagation maps to `parent`. The cause is runtime-only; durable `turn/end` stays coarse `aborted`. - `agent.whenIdle()` — resolve once the agent reaches quiescence after settling out of `running` (idle → immediately; disposed → awaits the loop exit). A non-owner's quiescence-observation hook: it observes the work settling WITHOUT tearing the agent down. Teardown is separate — a lifecycle owner stops and unregisters via `AgentHandle.dispose()`, which awaits the loop exit directly. - `agent.session`, `agent.status`, `agent.options`, `agent.id` diff --git a/packages/core/agent/package.json b/packages/core/agent/package.json index bcf75ea7ca..f40a5da441 100644 --- a/packages/core/agent/package.json +++ b/packages/core/agent/package.json @@ -11,11 +11,16 @@ "types": "./lib/types/index.d.ts", "default": "./lib/index.js" }, + "./invariant": { + "types": "./lib/types/invariant.d.ts", + "default": "./lib/invariant.js" + }, "./src/*": "./src/*", "./package.json": "./package.json" }, "files": [ "lib/index.js", + "lib/invariant.js", "lib/types/**/*.d.ts", "lib/types/**/*.d.ts.map", "src" @@ -23,6 +28,7 @@ "license": "BSD-3-Clause", "peerDependencies": { "@deepseek-ai/dsh-brand": "^0.0.1", + "@deepseek-ai/dsh-invariants": "^0.0.1", "@deepseek-ai/dsh-llm": "^0.0.1", "@deepseek-ai/dsh-scope": "^0.0.1", "@deepseek-ai/dsh-session": "^0.0.1", @@ -31,6 +37,7 @@ }, "devDependencies": { "@deepseek-ai/dsh-brand": "workspace:^", + "@deepseek-ai/dsh-invariants": "workspace:^", "@deepseek-ai/dsh-llm": "workspace:^", "@deepseek-ai/dsh-scope": "workspace:^", "@deepseek-ai/dsh-session": "workspace:^", diff --git a/packages/core/agent/src/cancellation.ts b/packages/core/agent/src/cancellation.ts new file mode 100644 index 0000000000..708009b456 --- /dev/null +++ b/packages/core/agent/src/cancellation.ts @@ -0,0 +1,30 @@ +/** Runtime reason inspection for explicit turn cancellation. @module @deepseek-ai/dsh-agent/cancellation */ + +import type { AgentInterruptReason } from './types.ts' + +/** + * Read a supported agent interruption from an explicitly supplied signal. + * Unknown reasons return `undefined`; ambient initiator identity does not grant + * cancellation authority. + * @param signal - the current turn's explicit control signal. + * @returns its canonical reason, or `undefined` while live or unsupported. + */ +export function agentInterruptReasonOf(signal: AbortSignal): AgentInterruptReason | undefined { + if (!signal.aborted) return undefined + const reason: unknown = signal.reason + if (typeof reason !== 'object' || reason === null || Array.isArray(reason)) return undefined + const prototype = Object.getPrototypeOf(reason) as unknown + const keys = Reflect.ownKeys(reason) + if ((prototype !== Object.prototype && prototype !== null) + || keys.length !== 1 || keys[0] !== 'kind') return undefined + switch ((reason as { readonly kind?: unknown }).kind) { + case 'user': + return Object.freeze({ kind: 'user' }) + case 'parent': + return Object.freeze({ kind: 'parent' }) + case 'disposed': + return Object.freeze({ kind: 'disposed' }) + default: + return undefined + } +} diff --git a/packages/core/agent/src/dispatch.ts b/packages/core/agent/src/dispatch.ts index 9d024d36be..8ce018c16b 100644 --- a/packages/core/agent/src/dispatch.ts +++ b/packages/core/agent/src/dispatch.ts @@ -115,8 +115,9 @@ export function agentEvents(ctx: Context, agent: Agent): AgentEventDispatch { * Build the prompt assembly context with agent and scope set together, so * agent-scoped prompt and tool contributions cannot be silently omitted. * @param agent - the agent the assembly is for. + * @param signal - the current turn's explicit control signal, when assembly belongs to a turn. * @returns the context to pass to `assemble()`. */ -export function assembleContextFor(agent: Agent): AssembleContext { - return { agent, scope: agent } +export function assembleContextFor(agent: Agent, signal?: AbortSignal): AssembleContext { + return { agent, scope: agent, ...signal === undefined ?

the opaque dispatch `thisArg` for a scope-filtered event. It composes `base`'s existing `Context.filter` with the scope predicate (untagged listener ⇒ admitted; tagged ⇒ admitted iff tag === key; `key === undefined` ⇒ untagged only). The carrier contains routing state only; the real subject is carried by the event arguments. `{ global: true }` listeners bypass filtering (Cordis semantics). - `Scoped` The compile-time opaque carrier brand: scope-filtered events demand it as their `this` type, so dispatching with a bare subject is a compile error. The type parameter records the subject type but does not expose its properties. - `isScopeCarrier(value)` / `carrierKeyOf(value)` Runtime carrier marks, used by the dev invariants to assert every scope-filtered dispatch carries a carrier keyed to the subject its arguments name. +- `ScopeLayer` Aggregate contract for one registry's complete global or exact-scope contribution; `isEmpty()` controls scoped-layer reclamation. +- `ScopedLayers` Own one eager global layer and lazy exact-scope layers. `peek()` never creates, `merge()` materializes insertion-ordered named shadows, and `effect()` derives visibility and ownership from the same context while returning the exact Cordis disposer. +- `NamedEntries` Insertion-ordered named storage with caller-owned duplicate diagnostics, lookup, and live iteration within one nonempty table generation; draining the table detaches existing iterators from later insertions, and `insert()` returns an idempotent exact-entry undo. +- `AnonymousEntries` Insertion-ordered anonymous storage whose unique internal keys keep equal values as independent registrations; it uses the same drained-generation iterator boundary, and `append()` returns an idempotent exact-entry undo. + +The optional `@deepseek-ai/dsh-scope/invariant` companion owns that runtime assertion. It uses the generated `scoped-events.generated.ts` resolver map to require a carrier for every declared scoped event and, when the payload exposes its routing subject, require identity with the carrier key. The Program-backed generator derives the map from event declarations and real `scopeTarget(base, key)` calls. ## Design contract The registration context determines both visibility and ownership, preventing a registration from being visible in one scope but disposed with another. Scopes route trusted same-process plugins; they are not sandboxes or authority boundaries. See the [agent-scope Agent Note](../../../.agents/notes/implemented/architecture/2026-07-08-agent-scope-contexts.md#security-and-authority-are-explicit-non-goals) for rationale and security non-goals. +Scope-aware services define a concrete `ScopeLayer` that aggregates their heterogeneous tables and domain helpers. `ScopedLayers.effect()` accepts one synchronous action returning one synchronous undo, installs that undo before optional notification, and reclaims an exact-scope layer only when the complete aggregate is empty. `notify` defaults to `true`; the supplied callback owns whether observer failures throw or are contained. `EntryValues` remains internal, the storage classes are imported from the package root rather than a `/store` subpath, and the shared storage does not define registry-specific filtering or iteration policy. See the [shared scoped-layer storage Agent Note](../../../.agents/notes/implemented/architecture/2026-07-12-scoped-layers-store.md). + Handing out a scoped context hands out the minting plugin's service-resolution surface (resolution walks the minting fiber's dependency chain, not the holder's) — mint it from the plugin whose dependencies the scoped registrations need to resolve. ## Known Limitations and Deferred Work diff --git a/packages/core/scope/package.json b/packages/core/scope/package.json index 88d78ceb8b..4679e2755a 100644 --- a/packages/core/scope/package.json +++ b/packages/core/scope/package.json @@ -11,20 +11,27 @@ "types": "./lib/types/index.d.ts", "default": "./lib/index.js" }, + "./invariant": { + "types": "./lib/types/invariant.d.ts", + "default": "./lib/invariant.js" + }, "./src/*": "./src/*", "./package.json": "./package.json" }, "files": [ "lib/index.js", + "lib/invariant.js", "lib/types/**/*.d.ts", "lib/types/**/*.d.ts.map", "src" ], "license": "BSD-3-Clause", "peerDependencies": { + "@deepseek-ai/dsh-invariants": "^0.0.1", "cordis": "^4.0.0-rc.7" }, "devDependencies": { + "@deepseek-ai/dsh-invariants": "workspace:^", "cordis": "^4.0.0-rc.7" } } diff --git a/packages/core/scope/src/index.ts b/packages/core/scope/src/index.ts index f09844e9ab..fc5b1fa5fa 100644 --- a/packages/core/scope/src/index.ts +++ b/packages/core/scope/src/index.ts @@ -8,6 +8,9 @@ import type { Context, Fiber } from 'cordis' import { Context as CordisContext } from 'cordis' +export { AnonymousEntries, NamedEntries, ScopedLayers } from './store.ts' +export type { ScopeLayer } from './store.ts' + /** An opaque, identity-compared scope key. */ export type ScopeKey = object diff --git a/packages/core/scope/src/invariant.ts b/packages/core/scope/src/invariant.ts new file mode 100644 index 0000000000..a5bd59f263 --- /dev/null +++ b/packages/core/scope/src/invariant.ts @@ -0,0 +1,41 @@ +/** Package-owned scoped-dispatch invariants. @module @deepseek-ai/dsh-scope/invariant */ + +import type { Context } from 'cordis' +import type { InvariantInstaller } from '@deepseek-ai/dsh-invariants' +import { carrierKeyOf, isScopeCarrier } from '@deepseek-ai/dsh-scope' +import { scopedSubjectResolverFor } from './scoped-events.generated.ts' + +const PACKAGE_NAME = '@deepseek-ai/dsh-scope' + +/** Cordis companion plugin name. */ +export const name = 'scope-invariant' +/** Services required before the companion can register. */ +export const inject = ['invariants'] + +/** Install the scoped-dispatch contribution into its child registration fiber. */ +const install: InvariantInstaller = (ctx, fail) => { + ctx.on('internal/dispatch', (_mode, eventName, args, thisArg) => { + const subjectOf = scopedSubjectResolverFor(eventName) + if (subjectOf === undefined) return + if (!isScopeCarrier(thisArg)) { + fail( + `"${eventName}" is a scope-filtered event but was dispatched without a scope carrier — ` + + 'pass scopeTarget(base, subject) as the dispatch thisArg (agent events: use agentEvents(ctx, agent))', + ) + } + if (subjectOf !== null && carrierKeyOf(thisArg) !== subjectOf(args)) { + fail( + `"${eventName}" was dispatched with a scope carrier keyed to a DIFFERENT subject than its arguments name — ` + + 'the carrier key and the event\'s subject must be the same object (use agentEvents(ctx, agent))', + ) + } + }, { global: true }) +} + +/** + * Register the scope invariant companion. + * @param ctx - Cordis context carrying the invariant service. + * @returns the installed registration's disposer after setup succeeds. + */ +export const apply = (ctx: Context): Promise<() => void> => + Promise.resolve(ctx.invariants.register(PACKAGE_NAME, install)) diff --git a/packages/core/scope/src/scoped-events.generated.ts b/packages/core/scope/src/scoped-events.generated.ts new file mode 100644 index 0000000000..5988b58145 --- /dev/null +++ b/packages/core/scope/src/scoped-events.generated.ts @@ -0,0 +1,52 @@ +/** + * Generated scoped-event routing-subject resolvers for dsh-scope invariants. + * Do not edit by hand;

Section texts arrive resolved but not yet interpolated; `variables` holds every registered variable resolved against the context. Tool schemas are part of the assembly by design: "what the model is told it can do" is one coherent thing, even though adapters transmit schemas as a separate wire field. - `renderPrompt(assembly)` — interpolates `{{variable}}` references in each section, drops empty sections, joins with blank lines.

see (without the `execute` functions). The shipped tools' schemas are catalogued in [docs/tool-catalog.md](../../../docs/tool-catalog.md), generated by booting each tool plugin and harvesting this method (see [the tool-schema-catalog Agent Note](../../../.agents/notes/implemented/process/2026-07-02-tool-schema-catalog.md)). - `ctx.tools.guard(guard: ToolGuard): () => void` Register a monotonic synchronous execution guard after `tools/pre-execute`: returning a reason denies the call, while `undefined` leaves it unchanged.

Around wrappers may replace only `signal`; the registry re-fuses the original caller signal immediately before the body. - `ctx.tools.executionMode(exec)` returns `parallel` only when the visible definition's `isConcurrencySafe(exec.arguments)` classifier returns exactly `true`; unknown, hidden, undeclared, invalid, or throwing classifications are exclusive. ### Injected services `SystemPrompt` — the registry automatically feeds its tool schemas into the system-prompt assembly via `ctx.systemPrompt.tools()`. The approval seam is consumed opportunistically instead (`ctx.get('approval')`, no static inject): a deployment without it keeps the ask→deny degrade, and the registry stays active either way. +### Cancellation + +Cancellation is cooperative and quiescent. Every typed invocation supplies a caller-owned `AbortSignal`; tool bodies receive it as required readonly `exec.signal`, while only `tools/execute` wrappers may temporarily replace the required signal. The registry preserves caller cancellation through replacement and never races away from a started same-process promise. Cancellation before body invocation is `ABORTED_BEFORE_DISPATCH`; cancellation after invocation can replace only a successful outcome with `ABORTED`. A denial, wrapper failure, tool failure, post-policy failure, or timeout-owned `TOOL_TIMEOUT` remains more specific. A pre-aborted entry materializes and freezes arguments, then skips every policy and dispatch phase and publishes one result. Every async tool must observe or forward the signal and settle only after owned work stops. The [tool-cancellation Agent Note](../../../.agents/notes/implemented/architecture/2026-07-19-cooperative-tool-cancellation.md) owns the full contract and hard-termination limit. + ### Live events The live registry pipeline has three transformable waterfalls followed by the observe-only `tools/result` boundary; registry changes are deliberately unfiltered shared-state notifications. Exact signatures, dispatch modes, scope filtering, and failure-containment contracts live in the generated [Cordis event catalog](../../../docs/cordis-catalog/events.md), while the complete ordering is visualized in the generated [tool execution pipeline](../../../docs/tool-execution-pipeline.md). `tools/result` is live; the similarly named `tool/result` is the durable session event the agent loop appends afterwards. ### Key types -- `ToolDefinition` — `ToolSchema` + `execute(args, exec)`, optional presentation callbacks, cooperative `timeoutMs`, and optional per-call `isConcurrencySafe(args)` classification. -- `ToolExecutionInput` — the caller-supplied call description: `{ callId, name, arguments, agent?, parent?, signal? }`; callers may pass an enclosing execution's opaque token as `parent` but never choose the new execution's own token. +- `ToolDefinition` — `ToolSchema` + `execute(args, exec)`, whose async work must cooperatively stop through `exec.signal`, plus optional presentation callbacks, cooperative `timeoutMs`, and optional per-call `isConcurrencySafe(args)` classification. +- `ToolExecutionInput` — the caller-supplied call description: `{ callId, name, arguments, signal, agent?, parent? }`; `signal` is required and readonly, callers may pass an enclosing execution's opaque token as `parent`, and callers never choose the new execution's own token. - `ToolExecutionToken` — a fresh branded `Symbol` assigned by the registry. It supports equality correlation only and never crosses a model, log, or worker boundary. -- `ToolExecution` — the pipeline-owned call: immutable `{ token, callId, name, arguments, agent?, parent? }` identity plus optional operational `signal`, which an around wrapper may add, replace, remove, and restore. A nested call's `parent` is a `ToolExecutionToken`, not an execution object. -- `ToolRunContext` — the execution passed to a tool body, extending `ToolExecution` with `deferContext(context)`. Composite tools use it to ferry context produced by nested dispatches to the outer result even when the tool later throws; it never injects immediately. +- `ToolExecution` — the readonly pipeline view: immutable `{ token, callId, name, arguments, signal, agent?, parent? }`; the registry separately retains and re-fuses the original caller signal. `ToolDispatchExecution` is the `tools/execute`-only view whose required signal is mutable, so a wrapper may replace and restore it but cannot delete it. A nested call's `parent` is a `ToolExecutionToken`, not an execution object. +- `ToolRunContext` — the execution passed to a tool body, extending `ToolExecution` with `deferContext(context)`. Composite tools use it to ferry context produced by nested dispatches to the outer result even when the tool later throws or cancellation wins; it never injects immediately. - `ToolExecutionResult` — losslessly JSON-serializable outcome: `{ content, isError, error?, additionalContexts?, meta? }`. Call identity stays on the immutable `ToolExecution` supplied alongside the result instead of being duplicated on the outcome. The registry materializes and freezes the complete post-policy value before final observation. On failure with a `HarnessError`, `error: { name, code }` carries the structured failure class alongside the model-facing text. `additionalContexts` preserves each deferred or post-execute `HookContext` with its own source and durable JSON metadata; the loop buffers the array and appends each entry as a `context/message` after all `tool/result`s in the step. - `PreToolDecision` — `{kind:'allow'}` | `{kind:'deny', reason}` | `{kind:'ask', reason?}`. Input rewrite is deliberately not offered; `ask` is serviced by [`ctx.approval`](../../ui/user-approval/README.md) when mounted and otherwise degrades to deny. - `PostToolDecision` — `{kind:'accept', content?, additionalContexts?}` (keep the call successful, optionally replacing the model-facing content) | `{kind:'block', feedback, additionalContexts?}` (turn it into an `isError` whose content is the corrective feedback).

Both check cancellation before and after their asynchronous metadata probe, so an abort that lands in flight reports `FS_ABORTED` rather than stale absence. - **`readText` / `streamText`** — UTF-8 only. `readText` reads the whole file; `streamText` streams it in chunks (cross-chunk decoding) so a huge file never has to be held whole in memory. Both reject invalid UTF-8 and NUL-byte binary samples (`FS_NOT_TEXT`) and non-regular targets. The `read` tool (`@deepseek-ai/dsh-tool-fs`) decides which to call by size and owns the line windowing. - **`listDir`** — lists one directory level in stable `name.localeCompare()` order. Each entry carries the child basename, type, resolved child target (`displayPath` under the listed directory, `targetKey` as the realpath identity), and cheap stat metadata (`version`, plus `size` for regular files). It never opens or decodes file contents. Missing targets report `FS_NOT_FOUND`, file/special-file targets report `FS_NOT_DIRECTORY`, aborted calls report `FS_ABORTED`, permission failures report `FS_PERMISSION_DENIED`, and other listing or child metadata I/O failures report `FS_IO_ERROR`.

Canonical spellings use a lexical fast path; an identity-based ancestor fallback recognizes alias-equivalent roots such as Windows long names and 8.3 names without treating unrelated prefixes as contained. The target is re-canonicalized immediately before delegating, so an ancestor symlink swapped since the tool resolved it is caught. - `danger-full-access` — delegates unfenced. ## Threat model: a policy fence, not a kernel boundary The fence is a check in TRUSTED code over a MODEL-CONTROLLED path — the operations are the seam's own (open, rename), only the target path is untrusted, so canonicalize-then-contain is the complete answer to this surface. This mirrors the `code-runtime` stance: containment, not a security boundary. Kernel-grade isolation of untrusted CODE stays `ctx.bash`'s job ([`dsh-bash-sandbox`](../../bash/bash-sandbox/README.md)). The residual TOCTOU (an ancestor symlink swapped between the containment re-check and the syscall) is narrowed by re-canonicalizing immediately before the write and is accepted for this threat model; a kernel-tight boundary needs `openat2`-class primitives not worth their portability cost here. -A denial is a structured `FsError` (`FS_SANDBOX_DENIED`, carrying the effective mode) — no stderr text inference (unlike bash's kernel denials), because an in-process fence knows exactly what it refused. The model-facing `[sandbox: file access denied under mode]` marker and the one-approved-wider retry live in the tool layer (`dsh-tool-fs`), exactly as bash's do.

It queues one `` prompt with `GoalMessageSource`. Admission through `agent/prompt-submit` verifies the complete queued record and current goal both before and after downstream prompt hooks; only the accepted `user/message` increments `roundsStarted`. A reservation rejected as stale does not consume the round number. + +One goal round owns one ordinary session turn, and that turn may contain several model/tool steps. The driver pairs a reservation only with a `message` turn carrying its exact `GoalMessageSource`; merge-extensible plugin turn triggers do not admit or replace that reservation. Human messages remain ordinary turns and do not consume the goal cap. If human work enters the inbox before a reservation or joins its pending batch, automatic work yields until that work settles; a pending automatic prompt in a mixed batch is rejected and re-reserved only after the agent becomes idle. + +The retained prompt names the JSON-quoted objective and `round/maxGoalRounds`, treats the current workspace, tool results, and durable session state as authoritative, requires evidence before completion, and tells the model to leave the goal active when work remains. Quoting preserves multiline or tag-like objective text as data. Goal lifecycle mutations still require the independent authority checks in `dsh-tool-goal`. + +## Settlement policy + +| Durable turn outcome | Goal action | Automatic retry | +|---|---|---| +| `completed` with goal still active and armed | admit the next round, or block with code `round-limit` at the cap | yes | +| cancellation of a reserved/admitted goal round, or its `aborted` outcome | `paused` | no | +| cancellation with no goal-round attempt | keep durable phase; disarm activation | no | +| `error` with `RATE_LIMIT` or `QUOTA` | `blocked` with code `usage-limited` | no | +| other `error`, `max-tokens`, or a non-stale prompt rejection | `blocked` with a diagnostic code and message | no | +| durability failure, disposal, interruption, or unknown future outcome | disarm or block for inspection | no | + +A goal mutation made during its round supersedes settlement of the older revision. Completion, pause, blocking, and edits therefore remain authoritative even if the physical turn closes afterward. No abnormal result is retried automatically. + +## Lifecycle and durability + +`goal/changed` creates a durability obligation. Before queuing work, the driver awaits `ctx.sessions.flush()` and rechecks both the goal revision and competing input after the await. A closing flush failure arrives through `agent/error`; the driver associates it with the exact closed turn even if a later one-shot injection has appended another turn, then disarms before another round can start. + +Activation is never inherited when this plugin loads over an existing agent. `GoalService.disarm()` removes process-local authority without changing durable phase, revision, or history; explicit human-authorized resume records the later reactivation. The same rule applies after session resume and fork through the goal domain's `agent/session-start` handling. + +Cancellation is observe-before-act: the concrete loop emits `agent/cancel-requested` with its typed cause before clearing queues or aborting the turn. The plugin durably pauses an active goal only when the cancellation owns a reserved or admitted goal attempt; cancellation of unrelated human work merely disarms process-local continuation. If the pause mutation fails, the driver falls back to disarming. Plugin teardown closes admission, disarms every live goal, cancels an admitted round with the `parent` cause, and awaits the driver plus agent quiescence while its event fence remains installed. + +## Model Experience + +### Goal-round prompt + +#### What the model sees + +Each admitted round is one retained user-role `` block naming the full objective and positive round number. Earlier human messages, goal-state snapshots, assistant output, and tool records remain in the same session history. + +#### Token effect + +One fixed instruction block plus the objective is added per admitted round. Later requests resend retained rounds until compaction shadows them; no fresh agent or copied conversation prefix is created. + +#### KV Cache effect + +Append-only within an epoch: each admitted round extends the existing conversation after its reusable prefix. Compaction may replace the derived-history suffix and move the reusable boundary. + +## Known Limitations and Deferred Work + +- **No independent evaluator** — the model-facing goal policy decides when evidence is sufficient for completion and whether a blocker is semantically unchanged; evaluator-backed certification remains deferred. +- **Same-session execution only** — this package deliberately does not spawn a fresh agent, fork a session prefix, or implement Ralph-style independent attempts; that workflow belongs to its own plugin layer. +- **Accepted-queue unload race** — Cordis plugin unload is asynchronous. A goal prompt already accepted by the agent inbox can begin and consume its round before unload starts; teardown then cancels the request, disarms the goal, and awaits quiescence. No later round starts. +- **Round cap, not resource budget** — token, currency, time, and provider quota policies remain independent; observed `RATE_LIMIT` and `QUOTA` stops only map into the blocked reason code `usage-limited`. +- **No abnormal auto-retry** — transient provider and persistence failures require a later human-authorized resume rather than an implicit retry policy. diff --git

-0,0 +1,56 @@ +# @deepseek-ai/dsh-goal + +Event-sourced same-session goal state. The service retains one current completion objective in an agent's existing session while keeping permission to continue as process-local activation. The [goal-domain Agent Note](../../../.agents/notes/implemented/feature/2026-07-19-persisted-same-session-goal-domain.md) owns the design rationale; the [goal type catalog](../../../docs/core-data-structures/goal.md) records the literal data shapes. + +## Config + +```yaml +- id: goal + name: '@deepseek-ai/dsh-goal' + config: + defaultMaxGoalRounds: 256 +``` + +`defaultMaxGoalRounds` must be a positive safe integer. `create()` materializes this deployment default internally before committing a goal; a request-level value overrides it. + +## Service contract + +`ctx.goals` accepts only the exact live `Agent` instance registered under its id. `get()` returns a detached `GoalView`; mutations use a `GoalRef { id, revision }` compare-and-set fence and reject stale refs. The service exposes create, edit, pause, resume, complete, block, and clear verbs through the generated [service catalog](../../../docs/cordis-catalog/services.md). Creation default resolution is internal. `disarm()` is the lifecycle-only exception: it removes process-local continuation authority without writing a revision or emitting a mutation. + +At most one goal is current. Creation produces an active revision-one goal and arms it. A non-complete goal must be edited, transitioned, or cleared; a completed goal may be replaced by a globally fresh id. Edits retain phase, blocker reason, and activation. Pause, completion, blocking, and clear disarm activation. A block records a policy-owned lower-kebab-case code plus a normalized free-form explanation; provider limits, configured budgets, execution errors, and requests for human input all use this one durable phase rather than multiplying lifecycle states. Resume accepts a stopped phase or a disarmed active goal only while the configured round cap has remaining capacity; it clears any former blocker reason. An active armed goal rejects the redundant operation. + +Every non-clear mutation appends a complete versioned snapshot through `agent.inject()`; clear appends a revisioned tombstone. The `context/message` content projected verbatim to the model, its `{ kind: 'goal' }` source, and its metadata must agree exactly. Replay rejects malformed shapes, source/content drift, discontinuous revisions, illegal lifecycle transitions, non-monotonic per-goal timestamps, and non-sequential goal rounds. Mutation timestamps clamp against the preceding goal update when wall time moves backward. + +Injection may append immediately or wait in an active tool-batch FIFO. The service overlays accepted pending changes in memory and reconciles each exact payload when it enters the log, so consecutive model-tool mutations see their own latest revisions without treating an unlogged cache as durable state. Reentrant append observers see each accepted mutation exactly once, and incremental replay retains its cursor at the first corrupt event. `goal/changed` fires after the append or enqueue succeeds; listener failures are contained. + +Activation is never persisted. A fresh cache and every `agent/session-start` edge disarm it even when replay finds an active durable phase. A continuation driver also calls `disarm()` before unload or after durability uncertainty. Session resume, fork, and driver replacement therefore retain the objective, phase, revisions, and admitted-round count without initiating work; a later explicit resume mutation must arm continuation. + +The separately published `./invariant` companion maintains an independent fold of each attached session. It rejects malformed goal metadata, source or model-visible content drift, discontinuous revisions, illegal lifecycle transitions, timestamp regressions, and non-sequential admitted rounds before the candidate event enters the durable log. + +## Extension points + +Policy plugins call the service verbs and react to the scoped `goal/changed` event. A continuation consumer admits rounds as `user/message` events with `GoalMessageSource`; ordinary human turns never increment `roundsStarted`. Consumers use the `Agent` interface and events rather than importing `dsh-agent-loop`. + +## Model Experience + +### Goal-state mutation + +#### What the model sees + +Each mutation is one raw user-role context block. A snapshot is rendered as `{"goal":...,"roundsStarted":...,"createdAt":...,"updatedAt":...}`; a clear renders the tombstone id/revision and `clearedAt`. There is no hidden state summary outside the log. The descriptive XML delimiter follows this repository's existing `` convention and [Anthropic's published XML-tag prompting guidance](https://platform.claude.com/docs/en/build-with-claude/prompt-engineering/claude-prompting-best-practices#structure-prompts-with-xml-tags); it is public model-experience prior art, not a claim about any provider's proprietary training corpus. + +#### Token effect + +Every retained mutation adds one full snapshot to derived history until compaction shadows it. Full snapshots make each record independently inspectable but repeat the objective and lifecycle fields. + +#### KV Cache effect + +Append-only within an epoch: each mutation follows the reusable request prefix and preceding history. Compaction may replace the derived-history suffix and move the reusable boundary. + +## Known Limitations and Deferred Work + +- **State, not scheduling** — this package does not decide when an armed goal continues, retry abnormal failures, or cancel an active turn; those policies belong to agent-seam consumers. +- **Round-count budget only** — `maxGoalRounds` does not meter tokens, currency, wall time, or provider quotas. +- **No independent evaluator** — the caller that records completion or blocking is authoritative; evaluator-backed certification is deferred to a separate policy layer. +- **One current goal** — parallel objectives and a separate goal database are intentionally absent; history remains available in the session log after replacement or clear. +- **Trusted in-process producers** — a plugin with direct `Session` access can append counterfeit goal metadata. Strict replay detects malformed or inconsistent records and leaves goal access failed at that record until the log is repaired; this is integrity detection, not plugin isolation. diff --git

The [goal-tool Agent Note](../../../.agents/notes/implemented/feature/2026-07-19-model-facing-goal-tools.md) owns the authority split and Codex-shaped UX. + +## Tools + +- `get_goal()` returns the current goal or `null`, including the compare-and-set id/revision, durable phase, admitted/capped goal rounds, any blocker reason, and current process-local activation. +- `create_goal(objective, max_goal_rounds?)` creates one goal from a direct top-level human turn. The model may infer long-running goal intent without an exact command phrase; non-human turns and subagents are rejected at execution. +- `update_goal(goal_id, revision, action, objective?, max_goal_rounds?, blocked_reason?)` supports `edit`, `pause`, `resume`, `complete`, and `blocked`. Replacements belong only to `edit`; `blocked_reason` is required only for `blocked` and is persisted with the stable code `model-reported`. + +All calls are exclusive, so a model-ordered batch observes earlier mutations and their new revisions. ACP and other clients receive pure generic cards: read for `get_goal`, other for mutations. + +An autonomous goal round that successfully reports `complete` or `blocked` contributes the existing terminal `agent/turn-stop` decision for that physical turn. Direct-human mutations never contribute this stop: the assistant may acknowledge the change and concurrent human steering remains available to the loop. + +## Authority + +Execution requires the exact live `exec.agent`, its inherited `AgentRegistry` initiator, running status, and an open turn. Create, edit, pause, and resume additionally require an accepted `{ kind: 'user' }` message or steering event in a runtime-root agent's current turn. Durable fork lineage does not demote a resumed root; live subagent ownership does. + +`{ kind: 'user' }` is a host attestation. `Agent.send()` and `steer()` assign it when their caller omits a source, so plugins, schedulers, and other non-human producers must pass their own source rather than inheriting human authority. + +Complete and blocked also accept the exact current goal round: a goal-sourced `user/message` whose id, revision, and round equal the folded current goal. A goal-round blocked call is mechanically rejected until `blockedAfterConsecutiveRounds`; the model judges whether the same condition actually persisted and must describe it in `blocked_reason`. Direct human authority may stop a goal immediately. + +## Config + +```yaml +- id: tool-goal + name: '@deepseek-ai/dsh-tool-goal' + config: + blockedAfterConsecutiveRounds: 3 +``` + +The value must be a positive safe integer.

The configured threshold is interpolated into that guidance. + +##### Goal policy + +```markdown +Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked. +``` + +#### Token effect + +Small fixed input cost on every request where this plugin's prompt registration is in scope. + +#### KV Cache effect + +Prefix-stable while the plugin scope, configured threshold, and guidance text are unchanged.

Calls, results, and resulting goal snapshots append after the reusable request prefix without invalidating earlier entries. + +## Known Limitations and Deferred Work + +- **Semantic intent remains model judgment** — execution can prove direct human provenance, not whether a request is substantial enough to merit a goal. +- **Same-condition blocking remains model judgment** — the runtime enforces distinct admitted-round count, not semantic equivalence of obstacles; an independent evaluator is deferred. +- **No scheduling or direct human rendering** — these tools mutate state only; the same-session driver and [`dsh-command-goal`](../command-goal/README.md) are independent consumers of the same domain. +- **Goal-round authority requires a driver** — the autonomous `complete`/`blocked` path is dormant unless a continuation driver admits goal-sourced user turns; mounting this tool package alone does not create them. +- **Prompt registration is independent of filtering** — a scope may hide the tools while retaining their guidance unless the deployment scopes both registrations together. diff --git a/packages/goal/tool-goal/package.json b/packages/goal/tool-goal/package.json new file mode 100644 index 0000000000..3fcc0c61a9 --- /dev/null +++ b/packages/goal/tool-goal/package.json @@ -0,0 +1,53 @@ +{ + "name": "@deepseek-ai/dsh-tool-goal", + "description": "Model-facing same-session goal tools with execution-time authority checks", + "version": "0.0.1", + "private": true, + "type": "module", + "main": "lib/index.js", + "types": "lib/types/index.d.ts", + "exports": { + ".": { + "types": "./lib/types/index.d.ts", + "default": "./lib/index.js" + }, + "./invariant": { + "types": "./lib/types/invariant.d.ts", + "default": "./lib/invariant.js" + }, + "./src/*": "./src/*", + "./package.json": "./package.json" + }, + "files": [ + "lib/index.js", + "lib/invariant.js", + "lib/types/**/*.d.ts", + "lib/types/**/*.d.ts.map", + "src" + ], + "license": "BSD-3-Clause", + "peerDependencies": { + "@deepseek-ai/dsh-agent": "^0.0.1", + "@deepseek-ai/dsh-goal": "^0.0.1", + "@deepseek-ai/dsh-invariants": "^0.0.1", + "@deepseek-ai/dsh-llm": "^0.0.1", + "@deepseek-ai/dsh-session": "^0.0.1", + "@deepseek-ai/dsh-system-prompt": "^0.0.1", + "@deepseek-ai/dsh-tools": "^0.0.1", + "cordis": "^4.0.0-rc.7" + }, + "dependencies": { + "schemastery": "^3.18.0" + }, + "devDependencies": { + "@cordisjs/plugin-loader": "workspace:^", + "@deepseek-ai/dsh-agent": "workspace:^", + "@deepseek-ai/dsh-goal": "workspace:^", + "@deepseek-ai/dsh-invariants": "workspace:^", + "@deepseek-ai/dsh-llm": "workspace:^", + "@deepseek-ai/dsh-session": "workspace:^", + "@deepseek-ai/dsh-system-prompt": "workspace:^", + "@deepseek-ai/dsh-tools": "workspace:^", + "cordis": "^4.0.0-rc.7" + } +} diff --git a/packages/goal/tool-goal/src/authority.ts b/packages/goal/tool-goal/src/authority.ts new file mode 100644 index 0000000000..41fe713dc6 --- /dev/null +++ b/packages/goal/tool-goal/src/authority.ts @@ -0,0 +1,109 @@ +/** Execution-time authority checks for the model-facing goal tools. */ + +import type { Context } from 'cordis' +import type { Agent } from '@deepseek-ai/dsh-agent' +import type { GoalView } from '@deepseek-ai/dsh-goal' +import { HarnessError } from '@deepseek-ai/dsh-llm' +import type { SessionEvent } from '@deepseek-ai/dsh-session' +import type { ToolRunContext } from '@deepseek-ai/dsh-tools' + +type TurnStartEvent = Extract + +/** Current open turn plus the events accepted after its start boundary. */ +export interface GoalToolExecution { + readonly agent: Agent + readonly start: TurnStartEvent + readonly events: readonly SessionEvent[] +} + +/** Hard authority granted to one state-changing call. */ +export type GoalToolAuthority = + | { readonly kind: 'direct-human' } + | { readonly kind: 'goal-round'; readonly goal: GoalView } + +/** Throw one structured tool-policy failure. */ +function reject(message: string, code = 'GOAL_TOOL_AUTHORITY_REQUIRED'): never { + throw new HarnessError(message, code) +} + +/** Locate the open turn enclosing a model tool call. */ +function openTurn(agent: Agent): { start: TurnStartEvent; events: readonly SessionEvent[] } { + const events = agent.session.events + for (let index = events.length -

The bridge tracks each run chain — the hook run PLUS its continuation — and registers `drain()` as its effect disposer: drain fires the tracker's abort `signal` (so a still-running hook process is killed via `runHook`, not awaited out to its timeout), then resolves once every tracked chain has settled. `fiber.dispose()` resolving therefore means no detached hook work is left to fire into a

Registering another adapter for `deepseek` throws `LlmError('DUPLICATE_ADAPTER')`. `reasoningEffort` is **omitted by default** — when unset, the `reasoning_effort` wire field is not sent and the server applies its own default for the model. The only accepted values are `high` and `max` (DeepSeek's official effort levels). It is meaningful only with thinking enabled (the provider default). `thinking`/`reasoningEffort` are adapter-level request defaults serialized as the official top-level `thinking: {type}` / `reasoning_effort` wire fields. They live in adapter config (not `GenerateOptions`) to keep the core vocabulary provider-neutral. +`streamIdleTimeoutMs` bounds each outstanding provider read, including the initial `fetch`, without counting time the consumer spends between chunks. One stable abort signal reaches the request and body reader for the whole call; expiry stops the transport and throws `LlmError('TIMEOUT')`, while an earlier caller abort throws `LlmError('ABORTED')`. The adapter makes exactly one provider request per `stream()` call; agent-level retry is a separate plugin policy. + ## App attribution Every request carries the shared attribution header from dsh-llm's `attributionHeaders()` - the mandatory `User-Agent` baseline identifying the harness (see [dsh-llm § App attribution](../llm/README.md#app-attribution-attributionts)). Direct DeepSeek requests and OpenAI-compatible gateway requests get no provider-specific app-attribution headers under this adapter contract; OpenRouter app attribution is deferred to a future explicit OpenRouter adapter or mode. @@ -42,11 +49,11 @@ Every request carries the shared attribution header from dsh-llm's `attributionH ## Errors -Non-2xx responses throw `LlmError` with stable codes: `AUTH` (401/403), `RATE_LIMIT` (429), `CONTEXT_WINDOW_EXCEEDED` (a 400 whose provider code, type, or message identifies context overflow), `INVALID_REQUEST` (other 400s), `SERVER` (5xx), `HTTP_` otherwise.

The finite budget caps attempts; `llm/retry` itself contributes no tokens. + +#### KV Cache effect + +The reconstructed request preserves the prior prefix and is eligible for provider cache reuse under that provider's rules. The non-surface status event does not change cache identity. + +## Known Limitations and Deferred Work + +- **Agent steps are the only retry boundary** — direct `ctx.llm.stream()` consumers remain single-attempt because a raw stream cannot separate already-emitted chunks durably. +- **Finite plugin budgets add** — this policy counts only configured transient codes; context-overflow compaction counts only its own code. A future policy with overlapping codes must document and test registration-order behavior. +- **`llm/retry` records scheduling, not completion** — later step and turn events establish success, exhaustion, or cancellation. diff --git a/packages/llm/llm-retry/package.json b/packages/llm/llm-retry/package.json new file mode 100644 index 0000000000..6d6c27636c --- /dev/null +++ b/packages/llm/llm-retry/package.json @@ -0,0 +1,54 @@ +{ + "name": "@deepseek-ai/dsh-llm-retry", + "description": "Bounded transient LLM request retry policy for the DeepSeek Harness", + "version": "0.0.1", + "private": true, + "type": "module", + "main": "lib/index.js", + "types": "lib/types/index.d.ts", + "exports": { + ".": { + "types": "./lib/types/index.d.ts", + "default": "./lib/index.js" + }, + "./invariant": { + "types": "./lib/types/invariant.d.ts", + "default": "./lib/invariant.js" + }, + "./package.json": "./package.json" + }, + "files": [ + "lib/index.js", + "lib/invariant.js", + "lib/types/**/*.d.ts", + "lib/types/**/*.d.ts.map", + "src" + ], + "license": "BSD-3-Clause", + "peerDependencies": { + "@deepseek-ai/dsh-agent": "^0.0.1", + "@deepseek-ai/dsh-invariants": "^0.0.1", + "@deepseek-ai/dsh-llm": "^0.0.1", + "@deepseek-ai/dsh-session": "^0.0.1", + "@deepseek-ai/dsh-timeout": "^0.0.1", + "cordis": "^4.0.0-rc.7" + }, + "dependencies": { + "schemastery": "^3.18.0" + }, + "devDependencies": { + "@cordisjs/plugin-include": "workspace:^", + "@cordisjs/plugin-loader": "workspace:^", + "@deepseek-ai/dsh-agent": "workspace:^", + "@deepseek-ai/dsh-agent-loop": "workspace:^", + "@deepseek-ai/dsh-invariants": "workspace:^", + "@deepseek-ai/dsh-llm": "workspace:^", + "@deepseek-ai/dsh-session": "workspace:^", + "@deepseek-ai/dsh-session-persistence-jsonl": "workspace:^", + "@deepseek-ai/dsh-session-persistence-sqlite": "workspace:^", + "@deepseek-ai/dsh-system-prompt": "workspace:^", + "@deepseek-ai/dsh-timeout": "workspace:^", + "@deepseek-ai/dsh-tools": "workspace:^", + "cordis": "^4.0.0-rc.7" + } +} diff --git a/packages/llm/llm-retry/src/index.ts b/packages/llm/llm-retry/src/index.ts new file mode 100644 index 0000000000..4edf22d6f2 --- /dev/null +++ b/packages/llm/llm-retry/src/index.ts @@ -0,0 +1,213 @@ +/** + * Bounded transient model-request retry policy on the agent loop's closed-step + * recovery seam.

Per-package errors (`LlmError`, `ToolArgsError`, `InvariantError`, …) extend it. `isHarnessError(value)` narrows at seams. -- `LlmError` — extends `HarnessError`; its stable `code` string (`NO_ADAPTER`, `DUPLICATE_ADAPTER`, and adapter codes like `AUTH`/`RATE_LIMIT`) is the programmatic failure contract. +- `LlmError` — extends `HarnessError`; its stable `code` string (`NO_ADAPTER`, `DUPLICATE_ADAPTER`, and adapter codes like `AUTH`/`RATE_LIMIT`) matches its frozen serializable `failure.code`. The payload may also retain validated status, `Retry-After`, and branded provider request id facts; policy remains outside the error. +- `errorChain(value)` — renders a thrown value with its full `cause` chain and AggregateError members for diagnostic surfaces (UI notices, logger lines, durable `turn/end` messages), so transport wrappers like undici's `TypeError: fetch failed` surface the underlying `ECONNREFUSED`/DNS/TLS detail instead of masking it. Rendering only — route on `code`, never by parsing the result. - `CONTEXT_WINDOW_EXCEEDED_CODE` — the provider-neutral code both DeepSeek adapters use when a request exceeds the model context window, regardless of thrown-HTTP versus in-band finish delivery. `isContextWindowExceededError(detail)` is their shared conservative classifier for OpenAI-compatible provider detail. +- `QUOTA_EXCEEDED_CODE` — the non-transient provider-neutral code for exhausted account quota, balance, credits, budget, or usage limits. `isQuotaExceededError(detail)` keeps those failures distinct from request-rate limits. ### Real adapters @@ -64,7 +69,7 @@ Pass-through; the registry preserves the assembled request prefix, while the sel ## Known Limitations and Deferred Work -- **No default retry/caching/rate-limit policy ships in this service** — `llm/stream` remains the call-wrapper seam; the agent loop separately offers proven model-request failures to `agent/request-error`, whose default preserves the original failure. +- **No default retry/caching/rate-limit policy ships in this service** — `llm/stream` remains a single-attempt call-wrapper seam; the agent loop separately offers proven model-request failures to `agent/request-error`, whose default preserves the original failure. `@deepseek-ai/dsh-llm-retry` is an optional policy plugin loaded by the shared example spine. - **`GenerateOptions` sampling is `temperature`/`maxTokens`/`stop` only** — no `tool_choice`, `top_p`, or penalty fields; the vocabulary grows when a producer lands ([dropped inert knobs](../../../.agents/notes/implemented/simplification/2026-07-04-drop-inert-request-knobs.md)). - **Producer-gated variants stay out until produced** — `prefill`, per-tool `strict`, block `cache` hints, and the `agent` message-source variant were pruned as producerless ([Agent Note](../../../.agents/notes/implemented/simplification/2026-07-04-prune-producerless-vocabulary-variants.md)). - **`BlockAssembler` handles core block kinds only** — a plugin-added block type whose stream is never closed by `block-end` makes `blocks()` throw. diff --git a/packages/llm/llm/package.json b/packages/llm/llm/package.json index ab11c8574f..9ef3e3323e 100644 --- a/packages/llm/llm/package.json +++ b/packages/llm/llm/package.json @@ -11,11 +11,16 @@ "types": "./lib/types/index.d.ts", "default": "./lib/index.js" }, + "./invariant": { + "types": "./lib/types/invariant.d.ts", + "default": "./lib/invariant.js" + }, "./src/*": "./src/*", "./package.json": "./package.json" }, "files": [ "lib/index.js", + "lib/invariant.js", "lib/types/**/*.d.ts", "lib/types/**/*.d.ts.map", "src" @@ -23,10 +28,12 @@ "license": "BSD-3-Clause", "peerDependencies": { "@deepseek-ai/dsh-brand": "^0.0.1", + "@deepseek-ai/dsh-invariants": "^0.0.1", "cordis": "^4.0.0-rc.7" }, "devDependencies": { "@deepseek-ai/dsh-brand": "workspace:^", + "@deepseek-ai/dsh-invariants": "workspace:^", "cordis": "^4.0.0-rc.7" } } diff --git a/packages/llm/llm/src/adapter-failure.ts b/packages/llm/llm/src/adapter-failure.ts index 745cbbdc64..390282327d 100644 --- a/packages/llm/llm/src/adapter-failure.ts +++ b/packages/llm/llm/src/adapter-failure.ts @@ -5,10 +5,10 @@ */ import { HarnessError } from './error.ts' -import type { StreamChunk } from './types.ts' +import type { LlmFailure, StreamChunk } from './types.ts' -/** Errors proven to originate in one model call's final adapter boundary. */ -export type AdapterFailureScope = WeakSet +/** Errors and normalized facts proven to originate in one model call's final adapter boundary. */ +export type AdapterFailureScope = WeakMap /** Call-local failure scopes keyed by the exact stream handle returned to a consumer. */ const adapterFailureScopes = new WeakMap, AdapterFailureScope>() @@ -47,10 +47,71 @@ export function markLlmAdapterFailure( const error = value instanceof Error ?

A crash fails the active query without replay; a later query may replace the process. +- Uses a compatibility-first **transient-open** sequence per query: canonicalize and read the source with Node APIs, `textDocument/didOpen` (version 1, full text), the requested request, then `textDocument/didClose` in `finally`. A failed or canceled `didOpen` write terminates the instance before the pool can reuse it. Documents close after each call, so the first version needs no `didChange`, content cache, or document LRU. +- Serializes each source-read/open/query/close lifecycle through one abortable per-workspace queue so queued calls read current source only when their turn starts; distinct workspaces run in parallel. +- Reads sources through Node filesystem APIs in the subprocess's host namespace — NOT `ctx.fs`, and emits no `fs/observed`: only the LSP result is model-visible, so a query does not satisfy read-before-write policy. + +## Configuration + +The `servers` record key is the stable provider id reserved on `ctx.lsp`; each value has this shape: + +| Server key | Default | Meaning | +|---|---|---| +| `command` | (required) | Executable to spawn — absolute, or resolved on the child PATH at load. Launch uses no shell. | +| `args` | `[]` | Arguments passed to the executable. | +| `env` | `{}` | Extra env merged on top of the credential-scrubbed ambient env (vars matching `KEY`/`SECRET`/`TOKEN` are not forwarded). | +| `extensionToLanguage` | (required) | Lowercase leading-dot extension → LSP language id (e.g. `{ '.ts': 'typescript' }`). | +| `initializationOptions` | `null` | Static `initialize` options forwarded to the server. | +| `configuration` | `null` | Static answer to every `workspace/configuration` item. | +| `maxMessageBytes` | `16000000` | Largest single framed message accepted from the server. | +| `maxStderrBytes` | `1000000` | Largest stderr tail retained for diagnostics. | +| `maxDocumentBytes` | `4000000` | Largest source file this host will open. | +| `shutdownTimeoutMs` | `5000` | Graceful `shutdown`/`exit` budget before escalation. | +| `killGraceMs` | `2000` | Grace for request cancellation and for SIGTERM→SIGKILL escalation. | + +`servers` must contain at least one entry, and every id must be non-empty. Timer budgets must be positive integers no greater than Node's `2_147_483_647` ms timer limit. All executables resolve at load after credential scrubbing; a bad later entry prevents every provider from registering. Processes launch lazily on the first matching query. + +## Protocol behavior + +Initialization advertises `general.positionEncodings: ['utf-16']`, `workspace: { workspaceFolders: true, configuration: true }`, `textDocument.hover.contentFormat: ['markdown', 'plaintext']`, and `linkSupport: true` for definition and implementation, with no dynamic registration. The server's returned capabilities are authoritative: an unsupported operation, or synchronization without transient open/close, fails the query. An omitted server `positionEncoding` defaults to `utf-16`; any other value is a protocol error. The client answers `workspace/configuration` from static config, accepts lifecycle bookkeeping requests, and rejects `workspace/applyEdit` — it never applies edits or runs commands. Navigation maps `Location` directly and `LocationLink` from `targetUri` + `targetSelectionRange`; hover normalization takes valid `MarkupContent.value`, preserves string `MarkedString`s, renders language-tagged values as fenced code, and joins arrays with one blank line. Missing results, malformed ranges or positions, and malformed hover encodings fail as structured `LSP_MALFORMED_RESPONSE` errors. + +## Security boundary + +The provider trusts its configured server and claims no sandbox confinement. It canonicalizes and reads source through Node APIs, rejecting a source that is missing, non-regular, non-UTF-8, oversized, or whose canonical path resolves outside the canonical workspace (symlink aliases share one instance). Result locations may be external, but an external path cannot become a query source. The first implementation therefore requires trusted host-local deployment; restricted, remote, or virtual workspaces require another provider. + +## Model Experience + +Indirectly, through `dsh-tool-lsp`, which surfaces this provider's normalized results; this host contributes no prompt or schema itself. + +#### KV Cache effect + +No direct invalidation; `dsh-tool-lsp` owns request-prefix changes. + +## Known Limitations and Deferred Work + +- **Trusted host-local only** — no sandbox confinement, no private cache/temp write contract; supporting untrusted binaries or restricted/remote/virtual workspaces requires a later process/filesystem contract and a different provider ([seam Agent Note](../../../.agents/notes/implemented/architecture/2026-07-15-lsp-capability-seam.md)). Containment resolves `realpath`, then opens the source through one handle with `O_NOFOLLOW | O_NONBLOCK` (final-component symlink guard plus nonblocking rejection of FIFOs) and a bounded read; a concurrent mutator that swaps an *ancestor* directory for a symlink between the resolve and the open is an accepted residual TOCTOU under this trusted-deployment model, not closed with non-portable `openat` segment walks. +- **Transient-open compatibility floor** — servers whose synchronization omits open/close (or advertise `None`) are unsupported even if closed-document queries would work; the pinned TypeScript e2e establishes one compatibility floor, not a cross-language claim. +- **Per-server/workspace serialization latency** — parallel agents sharing one server and workspace queue behind one process; long-lived workspace processes consume memory until disposal. diff --git a/packages/lsp/lsp-local/package.json b/packages/lsp/lsp-local/package.json new file mode 100644 index 0000000000..6815b1c917 --- /dev/null +++ b/packages/lsp/lsp-local/package.json @@ -0,0 +1,50 @@ +{ + "name": "@deepseek-ai/dsh-lsp-local", + "description": "Generic stdio language-server provider for the DeepSeek Harness LSP capability seam (ctx.lsp) — spawns configured servers, translates JSON-RPC, and serves transient-open goToDefinition/findReferences/goToImplementation/hover queries in the host filesystem namespace", + "version": "0.0.1", + "private": true, + "type": "module", + "main": "lib/index.js", + "types": "lib/types/index.d.ts", + "exports": { + ".": { + "types": "./lib/types/index.d.ts", + "default": "./lib/index.js" + }, + "./invariant": { + "types": "./lib/types/invariant.d.ts", + "default": "./lib/invariant.js" + }, + "./src/*": "./src/*", + "./package.json": "./package.json" + }, + "files": [ + "lib/index.js", + "lib/invariant.js", + "lib/types/**/*.d.ts", + "lib/types/**/*.d.ts.map", + "src" + ], + "license": "BSD-3-Clause", + "peerDependencies": { + "@deepseek-ai/dsh-brand": "^0.0.1", + "@deepseek-ai/dsh-invariants": "^0.0.1", + "@deepseek-ai/dsh-llm": "^0.0.1", + "@deepseek-ai/dsh-lsp": "^0.0.1", + "@deepseek-ai/dsh-timeout": "^0.0.1", + "cordis": "^4.0.0-rc.7" + }, + "dependencies": { + "schemastery": "^3.18.0" + }, + "devDependencies": { + "@deepseek-ai/dsh-brand": "workspace:^", + "@deepseek-ai/dsh-invariants": "workspace:^", + "@deepseek-ai/dsh-llm": "workspace:^", + "@deepseek-ai/dsh-lsp": "workspace:^", + "@deepseek-ai/dsh-timeout": "workspace:^", + "cordis": "^4.0.0-rc.7", + "typescript": "^6.0.3", + "typescript-language-server": "^5.0.0" + } +} diff --git a/packages/lsp/lsp-local/src/abort.ts b/packages/lsp/lsp-local/src/abort.ts new file mode 100644 index 0000000000..7790069e44 --- /dev/null +++ b/packages/lsp/lsp-local/src/abort.ts @@ -0,0 +1,48 @@ +/** + * Shared cancellation helpers for the local LSP provider's host-I/O, queue, and protocol phases. + * @module @deepseek-ai/dsh-lsp-local/abort + */ + +import { timeoutOf } from '@deepseek-ai/dsh-timeout' + +/** + * Build an abort Error carrying the signal's reason and preserving timeout classification. + * @param signal - the aborted signal whose reason to surface. + * @returns the timeout reason if present, else the Error reason, else a generic aborted Error. + */ +export function abortError(signal: AbortSignal): Error { + const timeout = timeoutOf(signal) + if (timeout !== undefined) return timeout + const reason: unknown = signal.reason + if (reason instanceof Error) return reason + return new Error('LSP query aborted') +} + +/** + * Throw the signal's classified abort error when it has already fired. + * @param signal - the optional query cancellation signal. + */ +export function throwIfAborted(signal?: AbortSignal): void { + if (signal?.aborted) throw abortError(signal) +} + +/** + * Await work while allowing a query signal to abandon its wait; the underlying work keeps its own + * handlers and continues to its owner-defined quiescence boundary. + * @param work - the owned asynchronous work. + * @param signal - optional query cancellation. + * @returns the work result, or a rejection carrying the classified abort reason. + */ +export function abortable(work: Promise, signal?: AbortSignal): Promise { + if (signal === undefined) return work + if (signal.aborted) return Promise.reject(abortError(signal)) + const canceled = Promise.withResolvers() + const onAbort = (): void => { canceled.reject(abortError(signal)) } + signal.addEventListener('abort', onAbort, { once: true }) + const normalized = work.catch((error: unknown) => { + /* v8 ignore next -- owned LSP promises reject with Error; coercion defends the generic helper. */ + throw error instanceof Error ?

The catalog owns feature options, required and non-default Cordis plugin config, feature requirements, resource contribution, and round-trip markers; create and config use the same registry and configurator. The ACP app option contributes the human-command and user-interaction services before the bridge. `SdkProject.open()` requires only readable root `package.json` and `cordis.yml`. A Cordis config entry anchors feature installation; a package present only through a linked NPM dependency closure leaves the feature absent. Once an owned Cordis config entry exists, an incomplete resource shape is `inconsistent` and cannot be modified automatically. diff --git a/packages/sdk/helper/package.json b/packages/sdk/helper/package.json index 8d95dafe66..1d9c6a2be2 100644 --- a/packages/sdk/helper/package.json +++ b/packages/sdk/helper/package.json @@ -10,10 +10,15 @@ ".": { "types": "./lib/types/index.d.ts", "default": "./lib/index.js" + }, + "./invariant": { + "types": "./lib/types/invariant.d.ts", + "default": "./lib/invariant.js" } }, "files": [ "lib/index.js", + "lib/invariant.js", "lib/assets", "lib/types/**/*.d.ts", "lib/types/**/*.d.ts.map", @@ -29,12 +34,14 @@ }, "peerDependencies": { "@deepseek-ai/dsh-brand": "^0.0.1", + "@deepseek-ai/dsh-invariants": "^0.0.1", "cordis": "^4.0.0-rc.7" }, "devDependencies": { "@deepseek-ai/dsh-brand": "workspace:^", "@deepseek-ai/dsh-hooks-claude": "workspace:^", "@deepseek-ai/dsh-hooks-codex": "workspace:^", + "@deepseek-ai/dsh-invariants": "workspace:^", "@deepseek-ai/dsh-session-persistence-jsonl": "workspace:^", "@deepseek-ai/dsh-session-persistence-sqlite": "workspace:^", "@deepseek-ai/dsh-tool-subagent": "workspace:^", diff --git a/packages/sdk/helper/src/features/builtin/app.ts b/packages/sdk/helper/src/features/builtin/app.ts index e4ff11af20..835a9a8710 100644 --- a/packages/sdk/helper/src/features/builtin/app.ts +++ b/packages/sdk/helper/src/features/builtin/app.ts @@ -29,7 +29,7 @@ const ID = featureId('app') function appProjectResources( profile: ProjectProfile, - runInterface: 'acp' | 'stdio' | 'embed', + runInterface: 'acp' | 'tui' | 'embed', ): readonly ProjectResource[] { const context = createProjectTemplateContext(profile, runInterface) const scripts = createAppPackageScripts(context) @@ -43,10 +43,10 @@ function appProjectResources( } class AppOption extends FeatureOption { - override readonly id: 'acp' | 'stdio' | 'embed' + override readonly id: 'acp' | 'tui' | 'embed' override readonly label: string - constructor(id: 'acp' | 'stdio' | 'embed', label: string) { + constructor(id: 'acp' | 'tui' | 'embed', label: string) { super() this.id = id this.label = label @@ -56,7 +56,7 @@ class AppOption extends FeatureOption { override markerConfigEntries(): readonly { id: string; name: string }[] { switch (this.id) { case 'acp': return [{ id: 'acp', name: '@deepseek-ai/dsh-acp' }] - case 'stdio': return [{ id: 'stdio', name: '@deepseek-ai/dsh-stdio' }] + case 'tui': return [{ id: 'tui', name: '@deepseek-ai/dsh-tui' }] case 'embed': return [] } } @@ -65,7 +65,7 @@ class AppOption extends FeatureOption { override matchesConfigEntries(entries: readonly { id: string; name: string }[], profile: ProjectProfile): boolean { if (this.id !== 'embed') return super.matchesConfigEntries(entries, profile) return entries.some(entry => entry.id === 'agent-loop' && entry.name === '@deepseek-ai/dsh-agent-loop') - && !entries.some(entry => entry.name === '@deepseek-ai/dsh-acp' || entry.name === '@deepseek-ai/dsh-stdio') + && !entries.some(entry => entry.name === '@deepseek-ai/dsh-acp' || entry.name === '@deepseek-ai/dsh-tui') } override contribution(profile: ProjectProfile): ProjectContribution { @@ -73,6 +73,10 @@ class AppOption extends FeatureOption { case 'acp': return new ProjectContribution([ ...appProjectResources(profile, this.id), + ...npmCordisConfigEntry(ID, { + id: 'commands', + name: '@deepseek-ai/dsh-commands', + }), ...npmCordisConfigEntry(ID, { id: 'user-interaction', name: '@deepseek-ai/dsh-user-interaction', @@ -83,7 +87,7 @@ class AppOption extends FeatureOption { config: { model: profile.runtime.model }, }, ['model'], config => requiredString(config, 'model')), ]) - case 'stdio': + case 'tui': return new ProjectContribution([ ...appProjectResources(profile, this.id), ...npmCordisConfigEntry(ID, { @@ -91,10 +95,10 @@ class AppOption extends FeatureOption { name: '@deepseek-ai/dsh-user-interaction', }), ...npmCordisConfigEntry(ID, { - id: 'stdio', - name: '@deepseek-ai/dsh-stdio', + id: 'tui', + name: '@deepseek-ai/dsh-tui', config: { - welcome: 'agent REPL ready.

It resolves the auxiliary route, frames exact selected human messages as JSON, records the exact dispatchable request, applies a language-aware title instruction, enforces input and output budgets, composes timeout and caller cancellation, assembles the stream, and returns normalized text with exact source seqs and model provenance. + +This package is a library, not a Cordis plugin. The provider plugins call `registerSessionTitleLlmProvider()` with their cadence and message selector; it validates shared config and delegates each revision to `generateSessionTitleWithLlm()`, so registration, route, prompt, cancellation, and validation behavior cannot drift between them. + +## Route and failure contract + +`provider` and `model` overrides are optional but must be supplied together as non-empty strings. Without that pair, the helper uses the exact provider/model route captured from the current session's logged `request/header`; an explicit refresh before any route exists therefore needs overrides. The helper measures the final JSON-framed user prompt, including seq fields, wrappers, and JSON escaping, against `maxInputBytes` before logging or dispatch instead of truncating it. Timeout and caller cancellation are rechecked while consuming the stream and after it completes, so a late successful result cannot be accepted even if an interceptor or adapter ignores abort. Malformed or empty output, tool calls, and non-stop finish reasons also reject; the session-title service decides whether that rejection is an automatic warning or an explicit caller failure. + +After route and input validation, the helper appends a log-only `session/title-llm-request` event before model dispatch. It contains the title-provider id, exact source seqs, route, system prompt, message list, and output-token cap used by the call. The append shares the title capability's per-session settlement queue, so a superseding request cannot collide with an earlier fallback, request record, or accepted-title flush. The dispatched envelope is deep-frozen to keep interceptors aligned with that record but deliberately lacks dsh-agent-loop's process-local request identity, so loop-only reconstruction observers do not compare it with the conversation header. A later model failure leaves that request record intact; validation failures that never become dispatchable requests do not create one. The event stays outside derived model history. + +## Configuration + +Every field is required except the paired route override; there are no library defaults. + +| Key | Contract | +|---|---| +| `targetWords` | Positive target word count for non-CJK titles. | +| `targetCjkCharacters` | Positive target character count for Chinese, Japanese, or Korean titles. | +| `maxInputBytes` | Positive UTF-8 byte ceiling for the final JSON-framed user prompt. | +| `maxOutputTokens` | Positive auxiliary generation token cap. | +| `timeoutMs` | Positive end-to-end deadline within the runtime timer limit. | +| `provider`, `model` | Optional explicit route; both or neither. | + +## Model Experience + +### Auxiliary title request + +#### What the model sees + +The title model receives a fixed system instruction to return one concise unadorned title in the input language, including the configured word and CJK-character targets. Its one user message contains a JSON array of the exact selected human messages and their seqs. + +#### Token effect + +The auxiliary request consumes tokens according to selected input size and `maxOutputTokens`. It is separate from the main agent request and does not add title text or framing to agent history. + +#### KV Cache effect + +No main-request invalidation. Auxiliary cache reuse is provider-specific; the fixed instruction is reusable while the JSON message array changes with each revision. + +## Known Limitations and Deferred Work + +- The helper accepts text output only and rejects tool calls; structured-output adapters and provider-specific prompt variants are not exposed. +- It enforces a byte ceiling for the whole framed user prompt rather than clipping individual messages or applying a retention policy. diff --git a/packages/session-title/session-title-llm/package.json b/packages/session-title/session-title-llm/package.json new file mode

asynchronous provider. Every accepted revision is a log-only `session/title` event; `foldSessionTitle()` and `ctx.sessionTitle.get()` select the latest event and return its event seq and timestamp. + +Only text blocks from human `user/message` events are eligible. The first eligible prompt schedules a fallback from its first words within the configured UTF-8 byte limit. Whitespace is normalized, terminal control sequences are removed, and truncation never splits a code point. Empty and non-text prompts wait for later eligible input. + +## Service: `SessionTitleService` (ctx key: `sessionTitle`) + +- `get(session)` folds the latest accepted title from a live or replayed log. +- `refresh(session, signal?)` materializes the fallback when needed, then explicitly runs the registered provider over the current eligible messages. Provider errors and caller cancellation reject; cancellation does not roll back a fallback append already entering durability. +- `register(provider)` installs the sole optional provider and returns its awaitable Cordis effect disposer. A second registration throws immediately; disposal aborts pending and active calls, waits for their settlement, and only then permits another provider to register. + +Automatic work never delays the main agent response. A provider starts only after a marked loop-built request's exact route matches the current logged `request/header`, including when the unchanged header needs no new snapshot. Its late completion joins an open turn or uses a flushed zero-step `session-title` turn through `ctx.sessions.appendOutOfBand()`. Automatic failures warn and retain the latest title. New all-message revisions, provider disposal, session disposal, and explicit refresh abort older work, and a stale completion cannot append. Concurrent explicit refreshes reserve their order before fallback durability waits, while overlapping automatic and explicit fallback requests share one session-local in-flight append. Service and bundled model-provider records use `appendSessionTitleOutOfBand()` to share a per-session settlement queue, so a replacement request record waits for an earlier title write without serializing the superseded model call itself. Service teardown cancels queued work and drains calls that ignore cancellation before unloading completes. + +Forks inherit title events in their seed unchanged. The first-message cadence does not automatically retitle a child; the all-messages cadence may append a new revision after the child receives a later human prompt. + +## Configuration + +All limits are required; the library supplies no defaults. + +| Key | Contract | +|---|---| +| `fallbackMaxWords` | Positive maximum whitespace-delimited words in the deterministic fallback. | +| `fallbackMaxBytes` | Positive maximum UTF-8 bytes in the fallback; must not exceed `maxTitleBytes`. | +| `maxTitleBytes` | Positive maximum UTF-8 bytes accepted from any source. | + +## Provider contract + +A provider supplies a branded stable id, automatic mode (`first-message` or `all-user-messages`), and `generate(request)`. The request carries the live session, all eligible messages through one fixed revision, the current logged main-request route when available, and cancellation. The result identifies a non-empty title, unique ordered source-message seqs from that request, and optional model provenance. The service normalizes and validates the result before it becomes durable. + +See the [session-title data structures](../../../docs/core-data-structures/session-title.md) and [implemented decision](../../../.agents/notes/implemented/feature/2026-07-21-log-backed-session-titles.md). + +## Model Experience + +### Session title state + +#### What the model sees + +Nothing. `session/title` is log-only and never enters the session surface, `deriveMessages()`, system prompt, tool schemas, or request prefix. + +#### Token effect + +The fallback and accepted provider revisions add zero tokens to the main agent request.

Shutdown waits for process exit, inherited stdio closure, and ACP parser exhaustion before resolving or propagating a child error, so captures are complete and callers can remove owned paths after either outcome. Snapshot and ordinary e2e suites share this process boundary; a test supplies only agent paths, cwd, environment overrides, and any permission policy. -- **`runScenario` (harness)** — boots the real agent bin as a subprocess via tsx (unbuilt, Loader path), drives it over ACP JSON-RPC stdio from a deterministic `input.json` script, tees raw stdout for the expected-output and purity checks, and harvests every persisted session JSONL (parent + subagent children, primary-first) after a graceful stdin-EOF shutdown. Parameterized by `AgentUnderTest` (`binScript`, `configPath`, `tsconfigPath` — absolute paths; the subprocess cwd is a temp dir outside the repo). Startup failures preserve captured agent stderr in the rejected diagnostic. -- **Normalizers** — pure functions turning the two captured surfaces into stable text: `normalizeStdout` (JSON-RPC ids → first-seen sequence; UUIDs/cwd → tokens; doubles as the stdout-purity check), `normalizeSessionLog` (times zeroed, `seq` kept), `scrubSystemPrompts` (prompt text → `{{system}}`), `scrubToolSchemas` (schema bulk → `{{tools}}`), and `scrubRequestHeaders` (all header bulk → `{{system}}`/`{{tools}}`/`{{messagePrefix}}` outside each pin, structure kept — [pinned-header Agent Note](../../../.agents/notes/implemented/testing/2026-07-06-pin-request-header-content-in-one-scenario.md)). -- **`defineAcpSnapshotSuite` (factory)** — registers the whole describe/it tree for a scenario table: per-scenario expected-output and re-persisted-log comparisons, record/refresh fixture write-back, rejection of structured `UNKNOWN_TOOL` results, the per-header-class pin (`system-prompt.expected.md` plus `tool-schemas.expected.json`) with its live uniformity guard, and the fixture guard block (no orphan scenario dirs, required files present, exactly one pin per class, every JSONL prompt/schema-scrubbed, non-pinning fixtures fully header-scrubbed). Each scenario directory's `session.jsonl` plus contiguous `session..jsonl` siblings are the ordered primary/child inventory; the scenario table does not duplicate their count. Must be called at vitest collection time. +- **`launchAcpTestAgent` (launcher)** — boots a source agent under tsx or a built `lib` agent under plain Node from a temp cwd, connects the SDK client over a raw-byte stdout tee, collects session updates and stderr, surfaces asynchronous spawn failures through startup, fails closed on unhandled permission requests, and owns graceful or signalled shutdown. Shutdown waits for process exit, inherited stdio closure, and ACP parser exhaustion before resolving or propagating a child error, so captures are complete and callers can remove owned paths after either outcome. When Windows accepts forced termination but publishes its exit marker asynchronously, shutdown gives that marker a bounded grace before treating fallback refusal as a second failure. Snapshot and ordinary e2e suites share this process boundary; a test supplies only agent paths, cwd, environment overrides, and any permission policy. +- **`runScenario` (harness)** — drives ACP JSON-RPC stdio from a deterministic `input.json` script through the launcher, tees raw stdout for the expected-output and purity checks, and harvests every persisted raw JSONL session log (parent and subagent children, primary-first) after graceful stdin EOF. `AgentUnderTest` supplies absolute `binScript`, optional `libBinScript`, `configPath`, and `tsconfigPath` paths because the subprocess cwd is outside the repo. Startup failures preserve captured agent stderr in the rejected diagnostic. +- **Normalizers** — pure functions turning the two captured surfaces into stable text: `normalizeStdout` (JSON-RPC ids → first-seen sequence; UUIDs/cwd → tokens; cwd-rooted separators selected as canonical `/` or host-native; `session_info_update.updatedAt` → `{{updatedAt}}`; doubles as the stdout-purity check), `normalizeSessionLog` (times zeroed, `seq` kept, the same cwd-path policy), `scrubSystemPrompts` (prompt text → `{{system}}`), `scrubToolSchemas` (schema bulk → `{{tools}}`), and `scrubRequestHeaders` (all header bulk → `{{system}}`/`{{tools}}`/`{{messagePrefix}}` outside each pin, structure kept — [pinned-header Agent Note](../../../.agents/notes/implemented/testing/2026-07-06-pin-request-header-content-in-one-scenario.md)). +- **`defineAcpSnapshotSuite` (factory)** — registers the whole describe/it tree for a scenario table: per-scenario expected-output and re-persisted-log comparisons, record/refresh fixture write-back, rejection of structured `UNKNOWN_TOOL` results, the per-header-class pin (`system-prompt.expected.md` plus `tool-schemas.expected.json`) with its live uniformity guard, and the fixture guard block (no orphan scenario dirs, required files present, exactly one pin per class, every JSONL prompt/schema-scrubbed, non-pinning fixtures fully header-scrubbed). Refresh preserves existing volatile fields by event position and gives a newly inserted `session/title` its preceding event's time, so feature-driven insertions do not churn the remainder of a fixture. Each scenario directory's `session.jsonl` plus contiguous `session..jsonl` siblings are the ordered primary/child inventory; the scenario table does not duplicate their count.

Each pinning directory stores the normalized full prompt sequence in generated `system-prompt.expected.md` and the corresponding full tool-schema sequence in generated `tool-schemas.expected.json`; `session.jsonl` stores `"system":"{{system}}","tools":"{{tools}}"` while retaining config, reason, and any model-visible prefix. A pin with legitimate mid-run header changes declares `expectedHeaderChanges`, which fixes the length of both sidecar sequences. +Every scenario compares `stdout.expected.jsonl` with cwd-rooted separators canonicalized to `/`. On Windows, `pinsNativeWindowsStdout` additionally compares the complete `stdout.expected.windows.jsonl` after the shared expected output and requires that sidecar exactly when enabled. A scenario whose driven behavior needs POSIX process semantics (e.g. cancelling a live bash call kills a detached process group) declares `posixOnly`, which skips its run test on Windows while the fixture guards keep covering its committed files everywhere. + The example also ships a `cordis.snapshot.yml` replay overlay next to its `cordis.yml` (the bin swaps them under `DSH_SNAPSHOT=replay` — [single-source replay config Agent Note](../../../.agents/notes/implemented/testing/2026-07-04-single-source-acp-replay-config.md)); replay fixtures are served by [`dsh-llm-replay`](../llm-replay/README.md), which this package points at via the `DSH_SNAPSHOT_*` env vars it sets on the child. `pnpm run test:snapshot:record` calls the live LLM and rewrites the recorded scenarios' model fixtures; `pnpm run test:snapshot:refresh` stays keyless, runs the replay overlay, and rewrites stdout, comparable session-log expected outputs, and each pin's prompt and tool-schema sidecars from the committed model scripts. Fixture roles, record/replay/refresh semantics, and scenario-table fields are documented on `Scenario` and in the [snapshot Agent Note](../../../.agents/notes/implemented/testing/2026-06-19-acp-snapshot-tests.md). Constraints: `suite.ts` imports vitest, so the package entry is importable only inside a vitest run (the launcher, harness, and normalizers have no such dependency but ship from the same entry). ACP-specific by design — the launcher speaks the SDK's `ClientSideConnection`. Permission round-trips are scriptable: `InputScript.permissionAnswers` is a FIFO queue of option-kind selections (`allow_once`, `reject_once`, …) the client maps to the agent-issued `optionId` at answer time; an absent or exhausted queue answers `cancelled`, and a kind the request never offered rejects the run (the agent is answered `cancelled`, so a tolerant agent cannot absorb the scenario bug). Session config options are scriptable too: the `setConfigOption` step switches a knob over `session/set_config_option`, and `setConfigOptionExpectError` asserts the bridge rejects an unknown id or out-of-vocabulary value (the error frame stays in the transcript). @@ -53,4 +55,4 @@ None; this package neither assembles nor sends a provider request. ## Known Limitations and Deferred Work - **Session harvest requires raw JSONL mode** — `runScenario` collects persisted `.jsonl` logs, so snapshot configs set `persistenceCompression: 'none'`; compressed JSONL and SQLite compositions have no snapshot-harvest path. -- **The subprocess boots the unbuilt tsx/Loader path only** — the built-bin artifact is guarded by the separate `built-bin` e2e smokes, never by this tier. +- **Built mode requires current artifacts** — run `pnpm run build` before selecting `DSH_EXAMPLE_MODE=lib`; source mode remains the zero-build path. diff --git a/packages/support/acp-snapshot/package.json b/packages/support/acp-snapshot/package.json index 9cf18e7824..e5e715238a 100644 --- a/packages/support/acp-snapshot/package.json +++ b/packages/support/acp-snapshot/package.json @@ -11,11 +11,16 @@ "types": "./lib/types/index.d.ts", "default": "./lib/index.js" }, + "./invariant": { + "types": "./lib/types/invariant.d.ts", + "default": "./lib/invariant.js" + }, "./src/*": "./src/*", "./package.json": "./package.json" }, "files": [ "lib/index.js", + "lib/invariant.js", "lib/types/**/*.d.ts", "lib/types/**/*.d.ts.map", "src" @@ -27,9 +32,11 @@ "vitest": "^4.1.8" }, "peerDependencies": { + "@deepseek-ai/dsh-invariants": "^0.0.1", "cordis": "^4.0.0-rc.7" }, "devDependencies": { + "@deepseek-ai/dsh-invariants": "workspace:^", "cordis": "^4.0.0-rc.7" } } diff --git a/packages/support/acp-snapshot/src/harness.ts b/packages/support/acp-snapshot/src/harness.ts index 0735338d9a..bef803d69e 100644 --- a/packages/support/acp-snapshot/src/harness.ts +++ b/packages/support/acp-snapshot/src/harness.ts @@ -18,8 +18,9 @@ import { cp, mkdtemp, readFile, readdir, rm } from 'node:fs/promises' import { existsSync } from 'node:fs' +import { createHash } from 'node:crypto' import { tmpdir } from 'node:os' -import { join, delimiter } from 'node:path' +import { basename, dirname, join, delimiter } from 'node:path' import { ClientSideConnection, PROTOCOL_VERSION, @@ -41,12 +42,15 @@ export type { AgentUnderTest } from './launcher.ts' * the client observes the selected update (`agent_message_chunk` by default), * then cancels and awaits completion.

This pure-listener plugin checks relationships among session events, agent states, scoped dispatches, and model requests; it does not own or change product behavior. +Configurable registry service for package-owned runtime invariant checks. The root plugin registers `ctx.invariants`; it contains no product checks or product-package imports. Every workspace package publishes a `./invariant` companion that registers its exact npm package name. -The plugin has no environment guard: it is active wherever it is registered. The default [`dsh-agent-spine-demo`](../../examples/agent-spine-demo/README.md) bundle mounts it unconditionally; a custom composition can omit it when the runtime cost is undesirable. It doubles as executable documentation of the event taxonomy — the assertions *are* the contract. +## Service: `InvariantService` (`ctx.invariants`) -Session itself owns immutable, surface-valid log storage in every composition: it takes one lossless JSON snapshot of each candidate, validates complete provenance and positional replacement, restricts `tool/result` replacement to one current result's `content`, deep-freezes the accepted record, and exposes the log through immutable array snapshots. The invariants plugin checks the remaining cross-record and cross-seam rules that Session does not own. +```ts +interface Config { + enabled?: boolean + package_allowlist?: string[] + package_blocklist?: string[] +} +``` -Session-log assertions run during Cordis `internal/dispatch`, while `Session.append()` is resolving the `session/event` callback snapshot but before it pushes the candidate into the log. A valid transition is staged by exact event identity and applied to the live trace only when that same committed event reaches the plugin's contained post-commit listener. A later internal dispatch check can therefore veto without advancing either the log or the invariant trace, while ordinary `session/event` observer failures remain observe-only. +Defaults are `enabled: true`, `package_allowlist: []`, and `package_blocklist: []`. A package is selected only when the service is enabled, the allowlist is empty or at least one allowlist pattern matches its full npm name, and no blocklist pattern matches. Blocklist matches therefore override allowlist matches. -## Plugin +Each entry is a case-sensitive JavaScript regular-expression source compiled with `new RegExp(pattern)`. Matching is unanchored unless the source supplies `^` and `$`; `/pattern/flags` syntax is not parsed. Blank, whitespace-padded, invalid, or duplicate entries within one list fail service startup. A valid pattern may match no currently loaded package so later loading and HMR remain deterministic. -A functional plugin — register the module namespace (this is what loading by name in `cordis.yml` does): +`ctx.invariants.register(packageName, installer)` reserves one active registration for the full npm package name, including when filters keep its installer inactive, and returns its disposer. An enabled contribution runs in a dedicated child Cordis fiber. The installer can declare its required service surface through `installer.inject` and receives `fail(message)`, which throws an `InvariantError` bound to the registering package. Synchronous or asynchronous installer completion is joined before registration succeeds; failure disposes the child and releases ownership atomically. + +The service owns every registration fiber, while the returned disposer also belongs to the companion fiber. Unloading either side removes listeners, trace state, and the reservation. A companion can therefore reload and register the same package name without retaining its previous state. Session-backed companions rebuild their baseline from durable events; live-only companions observe operations that begin after reload. + +`InvariantError` extends `Error`, carries stable `code: 'INVARIANT'`, and exposes the owning `packageName` without adding a product dependency to the service. + +Session itself owns immutable, surface-valid log storage in every composition: it takes one lossless JSON snapshot of each candidate, validates complete provenance and positional replacement, restricts `tool/result` replacement to one current result's `content`, deep-freezes the accepted record, and exposes the log through immutable array snapshots. The `dsh-session` invariant companion checks the remaining cross-record rules that Session does not own. + +## Package companions + +Publication and registration are exhaustive; runtime assertions are deliberately not synthetic. A companion installs a check only when its package owns an observable event relationship or relevant mutable-data relationship. Confirming a required method, plugin name, injection, effect, or fixed pure-function result is a type, load, or unit-test concern rather than a runtime invariant. + +When no plausible runtime relationship exists, the companion uses an empty installer with a package-specific leading `No runtime invariant:` comment explaining why. This is common for pure utilities, thin implementations whose behavior is already observed through their seam, composition-only packages, binaries, persistence adapters whose contracts require crash/round-trip tests, and test-support packages. The explanation must be revisited when the owner gains mutable state or an event protocol. + +The current executable companions protect these relationships: + +| Companion | Checks | +|---|---| +| `dsh-session`, `dsh-agent`, `dsh-scope`, `dsh-agent-loop` | Session enclosure and call/result trace, agent-status transitions, scoped subjects, and model-request reconstruction. | +| `dsh-llm`, `dsh-llm-retry`, `dsh-tools`, `dsh-system-prompt` | Stream grammar, durable retry position and bounds, tool-pipeline stages and frozen results, and authoritative prompt-assembly data. | +| `dsh-compact`, `dsh-hook-protocol`, `dsh-sandbox-policy` | Durable compaction and hook pairing, compaction metadata, and sandbox-mode vocabulary. | +| `dsh-fs`, `dsh-subagent`, `dsh-workflow` | Filesystem event identity, provider/child pairing, and workflow/agent lifecycle identity. | +| `dsh-goal`, `dsh-goal-session` | Durable goal source/content agreement, revision and lifecycle transitions, timestamps, sequential admitted rounds, and reconstructed continuation prompts. | +| `dsh-permission`, `dsh-user-approval` | Active-preset references and approval asked/decided audit pairing. | +| `dsh-tasks`, `dsh-tool-todo` | Task snapshot lifecycle/ownership fields and durable whole-list todo structure. | +| `dsh-time-context` | Durable clock readings agree with the session's open turn and next pre-step position and elapsed baseline; rendered time parses and does not postdate its event. | + +The root entrypoint of each owner remains independent of diagnostics. Loading the service alone installs no product checks, and loading a companion without the service waits on its declared `invariants` injection. + +`pnpm run verify-package-invariants` discovers all workspace packages. It rejects generated markers, unexplained empty installers, non-empty installers that omit or ignore the reporter, incorrect registration names, and incomplete export, publication, dependency, TypeScript-reference, or bundle wiring. This source rule is a minimum ownership check; focused tests prove each executable companion's semantics. + +## Composition ```ts import type { Context } from 'cordis' -import * as Invariants from '@deepseek-ai/dsh-invariants' +import InvariantService from '@deepseek-ai/dsh-invariants' +import * as SessionInvariant from '@deepseek-ai/dsh-session/invariant' declare const ctx: Context -await ctx.plugin(Invariants) +ctx.plugin(InvariantService, { + enabled: true, + package_allowlist: ['^@deepseek-ai/dsh-'], + package_blocklist: ['^@deepseek-ai/dsh-agent-loop$'], +}) +ctx.plugin(SessionInvariant) ``` -`inject`: `['sessions']` — it reads `ctx.sessions.list()` at apply time to rebuild trace state for sessions that already exist, so a hot reload mid-turn does not falsely reject the next event. The oracle listeners are explicitly global so pre-commit staging and post-commit application keep the same audience even if the plugin is mounted under a scoped context; their cleanup still belongs to that mounting fiber. The plugin has no configuration. +The standard agent spine mounts the service and its four core stateful companions. Custom compositions explicitly add companions for other loaded packages whose contracts they want checked; filters can disable or select registrations without changing package entrypoints. -## Invariants asserted - -Session log (per session): - -- **`seq` strictly increases** — the spine of replay equivalence. -- **turns pair and nest** — `turn/start` opens a turn, `turn/end` closes the matching one; no overlapping turns. -- **steps nest in turns** — `step/start` opens a step in the open turn; `step/end` closes the matching step. -- **chunks belong to an open step** — `step/start` precedes its `assistant/chunk`s. -- **an appended `tool/result` needs a prior `tool/call`** — fresh `surfaceOp: 'append'` results name the open step and consume its pending call. A Session-validated replacement is a turn-enclosed rewrite, not another execution. A `tool/call` may still have no result when the execution pipeline throws. - -Agent status (per agent): - -- **legal transitions only** — `idle↔running` and `(idle|running)→disposed`. A no-op transition (`setStatus` dedups, so it never fires) and leaving the terminal `disposed` state are violations. - -Model requests (on `llm/stream`): - -- **a loop-built request is exactly what the log reconstructs** — a frozen request with a live `sessionId` (the loop-built marker; hand-built one-shots like compaction's summarize are unfrozen and skipped) must carry frozen `messages` deep-equal to the derivation over the log prefix strictly before the in-flight step's `step/start` (rebuilt through a FRESH `Session`, so the live cache cannot vouch for itself — and boundary-correct: content logged after `step/start` legitimately belongs to the next request), and every non-content field must equal the latest logged `request/header` (see [the reconstructability Agent Note](../../../.agents/notes/implemented/architecture/2026-07-05-reconstructable-requests.md)). Registered with `prepend: true` so a short-circuiting `llm/stream` listener (the replay adapter) cannot silence it; prepend orders it against append-registered listeners only — correctness rests on the seq-bounded rebuild, never listener timing. - -On any violation it throws `InvariantError` (`code: 'INVARIANT'`). - -## Why runtime assertions remain useful - -Session enforces the per-record storage boundary at runtime, where a cast cannot bypass it. Pervasive `DeepReadonly` types would add noise across consumers without expressing relationships such as turn/step nesting, subject-correct scoped dispatch, or equality between a request and its log reconstruction. This plugin checks those relationships wherever it is mounted while `dsh-session` keeps history immutable in every composition. See [source-owned session immutability and dev-mode invariants](../../../.agents/notes/implemented/architecture/2026-06-11-dev-invariants-over-deep-readonly.md). - -## Seeded sessions - -A seeded or forked session arrives with events already in its log because construction does not emit `session/event` for each seed record. `Session` validates, snapshots, and freezes every seed record before accepting it; on `session/created`, this plugin replays the accepted log only to rebuild and check its relational trace state. +Every ordinary Vitest topology mounts an explicitly enabled service and the current test package's companion. Focused suites cover valid and invalid observations for executable companions, while one exhaustive topology mounts all companions to prove registration and disposal wiring. ## Model Experience -None, as this observer only validates events and frozen requests and never rewrites prompts, schemas, messages, or streams. +None, as the service and companions observe runtime events and mutable snapshots without altering prompts, messages, schemas, streams, or tool results. #### KV Cache effect -None; this package neither assembles nor sends a provider request. +None; invariant checks do not assemble or send provider requests. ## Known Limitations and Deferred Work -- **The request-reconstructability assertion covers loop-built requests only** — hand-built one-shots (e.g. compaction's summarize call) carry no live `sessionId` marker and are skipped. -- **Merge-extended event families get no family-specific assertions** — `compact/*` lock pairing and `hook/*` invoked/result pairing are not checked here; only the core turn/step/chunk/tool-result contract is. +- Request reconstruction covers requests explicitly marked by the loop before freezing; direct one-shot LLM calls remain outside that marker contract even when callers freeze them or attach a session id. +- Live-only lifecycle companions cannot reconstruct operations that began before their own reload. Standard and test compositions mount them before the corresponding operations begin. +- Regular-expression filters are fixed for the service lifetime; changing them requires ordinary Cordis plugin reload. diff --git a/packages/support/invariants/package.json b/packages/support/invariants/package.json index 59a425387b..d52dd0a14d 100644 --- a/packages/support/invariants/package.json +++ b/packages/support/invariants/package.json @@ -1,6 +1,6 @@ { "name": "@deepseek-ai/dsh-invariants", - "description": "Runtime event-contract assertions for DeepSeek Harness development diagnostics", + "description": "Registry service for package-owned DeepSeek Harness runtime invariants", "version": "0.0.1", "private": true, "type": "module", @@ -11,32 +11,28 @@ "types": "./lib/types/index.d.ts", "default": "./lib/index.js" }, + "./invariant": { + "types": "./lib/types/invariant.d.ts", + "default": "./lib/invariant.js" + }, "./src/*": "./src/*", "./package.json": "./package.json" }, "files": [ "lib/index.js", + "lib/invariant.js", "lib/types/**/*.d.ts", "lib/types/**/*.d.ts.map", "src" ], "license": "BSD-3-Clause", "peerDependencies": { - "@deepseek-ai/dsh-agent": "^0.0.1", - "@deepseek-ai/dsh-llm": "^0.0.1", - "@deepseek-ai/dsh-scope": "^0.0.1", - "@deepseek-ai/dsh-session": "^0.0.1", "cordis": "^4.0.0-rc.7" }, + "dependencies": { + "schemastery": "^3.18.0" + }, "devDependencies": { - "@deepseek-ai/dsh-agent": "workspace:^", - "@deepseek-ai/dsh-llm": "workspace:^", - "@deepseek-ai/dsh-scope": "workspace:^", - "@deepseek-ai/dsh-session": "workspace:^", - "@deepseek-ai/dsh-subagent": "workspace:^", - "@deepseek-ai/dsh-system-prompt": "workspace:^", - "@deepseek-ai/dsh-tools": "workspace:^", - "@deepseek-ai/dsh-user-approval": "workspace:^", "cordis": "^4.0.0-rc.7" } } diff --git a/packages/support/invariants/src/index.ts b/packages/support/invariants/src/index.ts index 91b4da4566..2e6194b59b 100644 --- a/packages/support/invariants/src/index.ts +++ b/packages/support/invariants/src/index.ts @@ -1,419 +1,200 @@ /** - * Runtime listeners that fail loudly when cross-event contracts are broken: - * turn and step nesting, scoped dispatch, status transitions, and request - * reconstruction.

The [plugin command registration Agent Note](../../../.agents/notes/implemented/feature/2026-07-19-plugin-command-registration.md) owns the boundary and protocol mapping. + +## Service contract + +`ctx.commands.register(definition)` registers one lowercase command name, description, optional ACP-compatible unstructured-input hint, and abortable handler. A registered command is available to every composed command adapter; a plugin that is incompatible with a deployment does not register there. A plain-context registration is global. A command-producing plugin mounted beneath `agent.ctx` declares its own `commands` injection and creates an exact agent-scoped definition; it shadows a global definition with the same name. This child-injection shape preserves the agent scope without making the core agent loop depend on a UI service. Duplicate names within one layer fail during registration. Every disposer is the exact Cordis effect disposer, and registration or removal notifies every `commands/change` observer so live adapters can refresh discovery; observer failures are logged and cannot veto the registry mutation or starve later observers. + +`list(agent)` returns immutable, name-sorted descriptors after scoped shadowing. `find(agent, name)` returns the corresponding definition. `execute(agent, line, signal)` uses `parseCommand()` and runs only a known command, returning `undefined` for invalid syntax or unknown names. + +`parseCommand()` recognizes a slash at byte zero, a lowercase name containing letters, digits, `_`, or `-`, and either end-of-input or whitespace. It returns every byte after the name as `rawInput`, including separator whitespace; consumers own their command-specific grammar and may normalize only what that grammar permits. + +Handlers return `success` or `error` plus optional UI text. Results are rendered directly by the adapter and never enter model history. The registry races handler completion against the supplied abort signal, but an uncooperative handler may continue its own external side effects after the caller stops awaiting it. + +## Composition + +The terminal and ACP app bundles mount this service with their consuming front door; the UI-less agent spine does not. Custom compositions that use `dsh-tui`, `dsh-acp`, or a command producer mount `@deepseek-ai/dsh-commands` explicitly. + +## Model Experience + +### Direct human commands + +#### What the model sees + +Nothing. Known slash commands execute in the UI command plane, and their `CommandResult` text is not submitted as a user message. Unknown slash-command input is rejected by shipped adapters instead of becoming a model prompt. + +#### Token effect + +Command discovery, execution, and UI output add no model tokens. A command plugin may separately mutate a model-visible domain through that domain's durable APIs. + +#### KV Cache effect + +Registry metadata, command input, and direct output never enter a model request and do not affect its cache. A mutated domain owns any later cache effect. + +## Known Limitations and Deferred Work + +- **Only unstructured text input** — the descriptor intentionally matches ACP's current unstructured command input; forms, completion schemas, and typed arguments remain command-owned parsing concerns. +- **No persisted command output** — adapters display results live, but the generic registry does not add them to the session log or reconstruct them after reconnect. +- **Cooperative side-effect cancellation** — dispatch stops awaiting on abort; handlers must honor the signal to stop work that has already escaped into external systems. diff --git a/packages/ui/commands/package.json b/packages/ui/commands/package.json new file mode 100644 index 0000000000..0a777d22d8 --- /dev/null +++ b/packages/ui/commands/package.json @@ -0,0 +1,42 @@ +{ + "name": "@deepseek-ai/dsh-commands", + "description": "Plugin-owned human command registry for DeepSeek Harness UI surfaces", + "version": "0.0.1", + "private": true, + "type": "module", + "main": "lib/index.js", + "types": "lib/types/index.d.ts", + "exports": { + ".": { + "types": "./lib/types/index.d.ts", + "default": "./lib/index.js" + }, + "./invariant": { + "types": "./lib/types/invariant.d.ts", + "default": "./lib/invariant.js" + }, + "./src/*": "./src/*", + "./package.json": "./package.json" + }, + "files": [ + "lib/index.js", + "lib/invariant.js", + "lib/types/**/*.d.ts", + "lib/types/**/*.d.ts.map", + "src" + ], + "license": "BSD-3-Clause", + "peerDependencies": { + "@deepseek-ai/dsh-agent": "^0.0.1", + "@deepseek-ai/dsh-invariants": "^0.0.1", + "@deepseek-ai/dsh-scope": "^0.0.1", + "cordis": "^4.0.0-rc.7" + }, + "devDependencies": { + "@deepseek-ai/dsh-agent": "workspace:^", + "@deepseek-ai/dsh-invariants": "workspace:^", + "@deepseek-ai/dsh-scope": "workspace:^", + "@deepseek-ai/dsh-session": "workspace:^", + "cordis": "^4.0.0-rc.7" + } +} diff --git a/packages/ui/commands/src/index.ts b/packages/ui/commands/src/index.ts new file mode 100644 index 0000000000..56f88a9f20 --- /dev/null +++ b/packages/ui/commands/src/index.ts @@ -0,0 +1,318 @@ +/** + * Plugin-owned human-command registry shared by interactive UI adapters. + * @module @deepseek-ai/dsh-commands + */ + +import { Context, Service } from 'cordis' +import type { Agent } from '@deepseek-ai/dsh-agent' +import { NamedEntries, ScopedLayers } from '@deepseek-ai/dsh-scope' +import type { ScopeKey, ScopeLayer } from '@deepseek-ai/dsh-scope' + +export const name = 'commands' + +const COMMAND_NAME = /^[a-z][a-z0-9_-]*$/u + +/** Immutable command input metadata compatible with ACP unstructured input. */ +export interface CommandInputDescriptor { + /** Placeholder shown before the user supplies free-form input. */ + readonly hint: string +} + +/** Invocation passed to one registered command handler. */ +export interface CommandInvocation { + /** Exact agent whose human-facing surface received the command. */ + readonly agent: Agent + /** Exact text following the registered command name, including separator whitespace. */ + readonly rawInput: string + /** Cancellation signal owned by the dispatching UI request. */ + readonly signal: AbortSignal +} + +/** Expected command outcome rendered directly by the dispatching UI. */ +export type CommandResult = + | { readonly kind: 'success';

The welcome banner, `> ` prompt, rendered transcript, and `[tool call]` / `[tool result]` terminal lines add no tokens. A replacement `tool/result` remains model-visible through the session surface but is not rendered as a second execution; stdio keeps the original full-fidelity result line. - -#### KV Cache effect - -Append-only; newly visible content follows the reusable request prefix and does not invalidate existing KV-cache entries. - -### Terminal user-interaction answers - -#### What the model sees - -When a consumer calls `ctx.userInteraction.ask()`, this provider renders the question in the terminal and returns selected option labels or `custom` text. Through `dsh-tool-ask-user`, closed stdin becomes `Error: ask_user_question cannot be answered because stdin is closed`; disposal or abort becomes `Error: ask_user_question was interrupted before the user answered`. - -#### Token effect - -Waiting and terminal prompts add no tokens; the resolved answer or error is model-visible only through the calling tool or plugin's result. - -#### KV Cache effect - -Append-only; newly visible content follows the reusable request prefix and does not invalidate existing KV-cache entries. - -## Known Limitations and Deferred Work - -- **One configured session receives stdin** — the session/event renderer can print output from any session, but input lines always drive the configured `sessionId` rather than routing by the visible label. -- **Terminal questions are text-only and sequential** — the provider queues asks, supports option labels plus custom text, and has no richer UI shapes such as file pickers or diff previews. -- **Closed stdin ends the terminal channel** — EOF rejects active or queued questions and exits after submitted work reaches idle; there is no reconnect path for a long-lived process. diff --git a/packages/ui/stdio/src/index.ts b/packages/ui/stdio/src/index.ts deleted file mode 100644 index ac22cf6730..0000000000 --- a/packages/ui/stdio/src/index.ts +++ /dev/null @@ -1,471 +0,0 @@ -/** - * The stdio app's readline UI: reads lines from stdin into `agent.send()` or - * `steer()`, renders the durable event stream to stdout, buffers startup input - * for one exact agent/session identity, and exits piped input only after - * submitted work reaches idle. - * - * This package is the independently composable stdio front door.

The latest logged session title becomes the header subtitle, with `welcome` before a title exists, and the terminal window title becomes ` — `. A durable `llm/retry` event retracts the failed step's live chunks and renders the scheduled retry count, delay, and failure in the transcript; success, exhaustion, and cancellation then settle through ordinary session events. The footer totals each logged model step's usage once, including failed attempts, while treating committed-message usage as a fallback for logs without a usage chunk. Its idle view compares token-meter pressure with `ctx.llm.resolveModelContext()` for the current route, displays `context unknown` when the adapter has no capacity metadata, and also shows tool-card mode and the current model with reasoning state; while the agent runs, an elapsed working indicator and `esc interrupt` replace that summary.

A slash at the start of the submitted line enters `ctx.commands` instead: known commands execute directly, unknown commands produce a warning, and neither path reaches the model. The TUI registers `/help`, `/model`, `/clear`, `/cancel`, `/reasoning`, `/tools`, `/redraw`, and `/exit` as agent-scoped definitions; every other effective command joins autocomplete and `/help` dynamically. Ctrl+C or Escape cancels a running turn. Tool cards collapse long bodies into a configurable head/tail preview; Ctrl+O toggles every card between its preview and full output. Ctrl+R toggles reasoning, Ctrl+L redraws, and Ctrl+D exits while idle. + +`/model` opens the advisory `ctx.llm` catalog as a keyboard selector: Up/Down moves, Enter selects, and Escape closes it. `/model ` still selects an unambiguous model id directly, while `/model /` selects an exact target. The configured target or latest logged request header initializes the selector, and an unlisted current model remains visible because catalogs are advisory. Selection is local to this TUI session. Prompt assembly snapshots the target for one step, replaces `{{provider}}` and `{{model}}`, and applies the same pair through `agent/request`; a switch during assembly therefore starts with a later step.

It demonstrates a specialized orchestration policy as an ordinary plugin over [`ctx.workflows`](../workflow/README.md) and [`ctx.subagents`](../../subagent/subagent/README.md): no Ralph mode or fresh-agent loop is added to `agent-loop`, and the same-session [goal domain](../../goal/goal/README.md) remains independent.

The deployment config's `maxRounds` is both the default and a ceiling on a call override. Every Ralph round starts one child through `subagentProvider`; that provider must exist, support structured output, and report `inheritsParentContext: false`. The configured provider is carried as `WorkflowStartRequest.subagentProvider`, so the fixed script cannot inspect or change routing and the ordinary model-written `workflow` tool gains no provider selector. The resolved round cap is also carried as `WorkflowStartRequest.maxTotalAgents`, coordinating the fixed loop with the engine's total-child backstop; the engine rejects a Ralph cap above its deployment ceiling before publishing a run. + +Each child receives only the immutable objective, its current Ralph round and cap, a shared-workspace-as-authority instruction, and the previous structured handoff. The workspace is long-term memory; parent conversation and prior child sessions are not seeded. Reports have `status: continue | complete | blocked`, a non-empty summary, evidence, next steps, and blocker text. Status-specific semantics and the serialized `maxHandoffChars` ceiling are validated inside the fixed workflow and again at the consumer boundary. Invalid, missing, or oversized reports fail the workflow instead of being truncated or mistaken for cap exhaustion. + +The successful terminal tool result is `complete`, `blocked`, or `budget-limited`, with the last bounded report and number of rounds started. Completion and blocker labels explicitly say that a worker reported the outcome; they are not independent certification. `maxResultChars` bounds the complete successful text including its envelope and truncation marker, without altering the validated report used as a cross-round handoff. + +An ordinary child failure produces an error naming the failed round and retaining the last successful handoff when one exists. Ralph does not retry that round. Fatal provider-start, transport, worker, or workflow failures remain workflow errors and may settle before the fixed script can return a handoff. Cancellation is also an error; partial output is never success. + +## Lifecycle and cancellation + +The caller's agent is the parent of every fresh child, preserving cwd and lineage without copying its conversation. `exec.signal` enters the workflow engine and is also bridged to `run.cancel()` for implementation independence.

The parent result appends after the reusable request prefix. + +## Known Limitations and Deferred Work + +- **Completion is worker self-declaration** — there is no independent evaluator or verifier deciding whether the objective is actually complete; evaluator policy and evaluator-driven continuation are deferred. +- **Foreground only** — there is no task id, background collection, process-resume checkpoint, scheduler, or wall-clock start policy. +- **The workspace is the only cross-round long-term memory** — one bounded report is the explicit handoff, and uncommitted conversational reasoning disappears with each child. +- **One round is one fresh child** — there is no within-round fan-out, model/provider switching, fork context, or model-call-selected provider. +- **Ordinary child failure is terminal for the run** — the fixed script reports the failed round and last successful handoff but does not retry; fatal workflow infrastructure failures can end before that state is returned. +- **Only round count bounds aggregate effort** — token, price, and elapsed-time budgets are deferred. diff --git a/packages/workflow/tool-ralph/package.json b/packages/workflow/tool-ralph/package.json new file mode 100644 index 0000000000..fb12147445 --- /dev/null +++ b/packages/workflow/tool-ralph/package.json @@ -0,0 +1,59 @@ +{ + "name": "@deepseek-ai/dsh-tool-ralph", + "description": "Model-facing fresh-agent Ralph loop over the workflow and subagent seams", + "version": "0.0.1", + "private": true, + "type": "module", + "main": "lib/index.js", + "types": "lib/types/index.d.ts", + "exports": { + ".": { + "types": "./lib/types/index.d.ts", + "default": "./lib/index.js" + }, + "./invariant": { + "types": "./lib/types/invariant.d.ts", + "default": "./lib/invariant.js" + }, + "./src/*": "./src/*", + "./package.json": "./package.json" + }, + "files": [ + "lib/index.js", + "lib/invariant.js", + "lib/types/**/*.d.ts", + "lib/types/**/*.d.ts.map", + "src" + ], + "license": "BSD-3-Clause", + "peerDependencies": { + "@deepseek-ai/dsh-agent": "^0.0.1", + "@deepseek-ai/dsh-invariants": "^0.0.1", + "@deepseek-ai/dsh-llm": "^0.0.1", + "@deepseek-ai/dsh-subagent": "^0.0.1", + "@deepseek-ai/dsh-system-prompt": "^0.0.1", + "@deepseek-ai/dsh-tools": "^0.0.1", + "@deepseek-ai/dsh-workflow": "^0.0.1", + "cordis": "^4.0.0-rc.7" + }, + "dependencies": { + "schemastery": "^3.18.0" + }, + "devDependencies": { + "@cordisjs/plugin-loader": "workspace:^", + "@deepseek-ai/dsh-agent": "workspace:^", + "@deepseek-ai/dsh-agent-loop": "workspace:^", + "@deepseek-ai/dsh-agent-loop-testkit": "workspace:^", + "@deepseek-ai/dsh-invariants": "workspace:^", + "@deepseek-ai/dsh-llm": "workspace:^", + "@deepseek-ai/dsh-session": "workspace:^", + "@deepseek-ai/dsh-subagent": "workspace:^", + "@deepseek-ai/dsh-subagent-inprocess": "workspace:^", + "@deepseek-ai/dsh-subagent-spawn": "workspace:^", + "@deepseek-ai/dsh-system-prompt": "workspace:^", + "@deepseek-ai/dsh-tools": "workspace:^", + "@deepseek-ai/dsh-workflow": "workspace:^", + "@deepseek-ai/dsh-workflow-workerthread": "workspace:^", + "cordis": "^4.0.0-rc.7" + } +} diff --git a/packages/workflow/tool-ralph/src/index.ts b/packages/workflow/tool-ralph/src/index.ts new file mode 100644 index 0000000000..3bfd438cf7 --- /dev/null +++ b/packages/workflow/tool-ralph/src/index.ts @@ -0,0 +1,456 @@ +/** + * Model-facing foreground Ralph loop over the workflow and subagent seams.

A run is holder-owned. Engine-plugin unload prevents new starts but does not revoke accepted runs. The holder must call `dispose()` on every path; disposal cancels remaining work and reaches or abandons quiescence within the documented bound. -`WorkflowStartRequest` contains `{ meta, script, args?, parent, signal? }`. `parent` attributes every child agent to the invoking agent. `meta` and `args` are plain data, not script fragments. +`WorkflowStartRequest` contains `{ meta, script, args?, subagentProvider?, maxTotalAgents?, parent, signal? }`. `parent` attributes every child agent to the invoking agent. `subagentProvider` optionally routes every child in that run without exposing provider choice to the script; omission uses the engine's configured provider. `maxTotalAgents` optionally lowers the engine's deployment ceiling for one run and is likewise invisible to the script. An implementation rejects invalid routes and limits synchronously. `meta` and `args` are plain data, not script fragments. `WorkflowRun` exposes `{ id, meta, result, cancel(reason?), dispose() }`. `WorkflowResult` contains `{ value, stopReason, error?, agentsStarted }`; `value` is plain JSON data or `null`. diff --git a/packages/workflow/workflow/package.json b/packages/workflow/workflow/package.json index 476866382a..b8ce1ebc7f 100644 --- a/packages/workflow/workflow/package.json +++ b/packages/workflow/workflow/package.json @@ -11,11 +11,16 @@ "types": "./lib/types/index.d.ts", "default": "./lib/index.js" }, + "./invariant": { + "types": "./lib/types/invariant.d.ts", + "default": "./lib/invariant.js" + }, "./src/*": "./src/*", "./package.json": "./package.json" }, "files": [ "lib/index.js", + "lib/invariant.js", "lib/types/**/*.d.ts", "lib/types/**/*.d.ts.map", "src" @@ -24,6 +29,7 @@ "peerDependencies": { "@deepseek-ai/dsh-agent": "^0.0.1", "@deepseek-ai/dsh-brand": "^0.0.1", + "@deepseek-ai/dsh-invariants": "^0.0.1", "@deepseek-ai/dsh-llm": "^0.0.1", "@deepseek-ai/dsh-session": "^0.0.1", "cordis": "^4.0.0-rc.7" @@ -31,6 +37,7 @@ "devDependencies": { "@deepseek-ai/dsh-agent": "workspace:^", "@deepseek-ai/dsh-brand": "workspace:^", + "@deepseek-ai/dsh-invariants": "workspace:^", "@deepseek-ai/dsh-llm": "workspace:^", "@deepseek-ai/dsh-session": "workspace:^", "cordis": "^4.0.0-rc.7" diff --git a/packages/workflow/workflow/src/invariant.ts b/packages/workflow/workflow/src/invariant.ts new file mode 100644 index 0000000000..f6b8b8ced2 --- /dev/null +++ b/packages/workflow/workflow/src/invariant.ts @@ -0,0 +1,136 @@ +/** Package-owned workflow lifecycle invariants. @module @deepseek-ai/dsh-workflow/invariant */ + +import type { Context } from 'cordis' +import type { InvariantFailure, InvariantInstaller } from '@deepseek-ai/dsh-invariants' +import type { + WorkflowAgentEndInfo, + WorkflowAgentInfo, + WorkflowResultInfo, + WorkflowRunInfo, +} from './types.ts' + +const PACKAGE_NAME = '@deepseek-ai/dsh-workflow' + +/** Cordis companion plugin name. */ +export const name = 'workflow-invariant' +/** Service required before the companion can reserve package ownership. */ +export const inject = ['invariants'] + +interface WorkflowTrace { + meta: string + agents: Map + starts: number +} + +/** Require every event for a run to retain its validated identity snapshot. */ +function traceFor( + traces: ReadonlyMap, + info: WorkflowRunInfo, + fail: InvariantFailure, +): WorkflowTrace { + const trace = traces.get(info.id) + if (trace === undefined) fail(`workflow event has no matching workflow/start for run ${JSON.stringify(info.id)}`) + if (trace.meta !== JSON.stringify(info.meta)) { + fail(`workflow event meta diverges from workflow/start for run ${JSON.stringify(info.id)}`) + } + return trace +} + +/** Assert the immutable identity fields shared by an agent pair. */ +function validateAgentEnd(start: WorkflowAgentInfo, end: WorkflowAgentEndInfo, fail: InvariantFailure): void { + if (start.label !== end.label || start.phase !== end.phase || start.childId !== end.childId) { + fail(`workflow/agent-end identity diverges from workflow/agent-start for seq ${end.seq}`) + } + const outcome: string = end.outcome + if (outcome !== 'completed' && outcome !== 'failed' && outcome !== 'cancelled') { + fail(`workflow/agent-end carries unknown outcome ${JSON.stringify(outcome)}`) + } +} + +/** Validate a terminal result against the accumulated run trace. */ +function validateWorkflowEnd(trace: WorkflowTrace, result: WorkflowResultInfo, fail: InvariantFailure): void { + if (trace.agents.size > 0) fail(`workflow/end has ${trace.agents.size} agent call(s) without workflow/agent-end`) + if (!Number.isSafeInteger(result.agentsStarted) || result.agentsStarted < trace.starts) { + fail('workflow/end agentsStarted must be a safe integer covering every observed agent start') + } + if (result.stopReason === 'completed' ?
