An **Agent Note** records a decision or proposal that shapes this codebase — the *why* and *what we gave up*, the parts code and docs can't carry.

The file records what was decided and what was rejected, and is **kept current with what actually shipped**: when the code later moves a file, renames a package, or changes a key/default, the Agent Note is updated in the same change to match (facts only — paths, names, structure — not the decision itself). See [implemented/AGENTS.md](implemented/AGENTS.md). + - **`rejected/`** — the proposal was considered and declined. Kept for the record so the rejection isn't re-litigated. +- **Class** (the nested folder) is the *kind* of decision — see [Classification](#classification) below. + +The date in the filename is when the topic was **first proposed** (per git history).

Only a purely mechanical or local edit with no behavioral, contractual, structural, process, or rationale change is exempt. An Agent Note is never edited into a *different decision*: supersede it with a new one and cross-link. Editing an `implemented/` Agent Note to track where its existing decision lives is required, not forbidden; see [implemented/AGENTS.md](implemented/AGENTS.md). + +## The file format + +Every Agent Note follows one in-file format, enforced by `pnpm run verify-agent-note-format` ([scripts/verify-agent-note-format.ts](../../scripts/verify-agent-note-format.ts), part of `doc-sync`); the rationale for the format — and the alternatives it rejected — is [the uniform-format Agent Note](implemented/process/2026-07-05-uniform-agent-note-format.md). + +### The header block + +The first three lines of every Agent Note are exactly: + +```markdown +# Agent Note: + +Status: <status> +``` + +followed by a blank line.

What follows depends on the lifecycle; recurring sections use these canonical names and nothing else, while genuinely bespoke technical sections (package topology, wire contracts, schemas) remain free-form between the required ones. + +#### `proposed/` + +```markdown +## Problem +## Proposal +…bespoke sections… +## Alternatives considered +## Acceptance criteria +## Risks +``` + +`## Proposal` is the intended change and may legitimately speak in the future tense — plans, migration steps, and open questions belong here while the work is unbuilt. `## Acceptance criteria` says what observable state means done. `## Risks` covers both what could go wrong and what the change knowingly gives up. + +#### `implemented/` + +```markdown +## Problem +## Decision +…bespoke sections… +## Alternatives considered +## Consequences +``` + +`## Decision` describes shipped reality in the present tense, and the whole file is kept current with it per [implemented/AGENTS.md](implemented/AGENTS.md). `## Consequences` records what the trade-off cost **and** bought.

The disposer is a **consumer capability** — a registry observer holding only the bare `Agent` cannot tear it down. The caller fiber and registered factory provider are structural co-owners: caller unload enforces structured ownership, while provider unload must stop old instances whose scoped dependency surface resolves through that provider. All three paths reach the same memoized teardown: stop the loop, await its exit and idle flushes (true quiescence, not just the `disposed` status flip), detach the agent, detach its session, and unwind its scope. Each public ID becomes reusable when its exact registry entry detaches; there is no separate reservation-release phase. Config-created agents are already owned by the `AgentLoop` fiber (the handle is discarded). ACP holds each session's disposer in its `SessionRecord` and runs it on disconnect/teardown, so a bare client disconnect leaves no registered agent and no session-store entry — even when `session/load` races teardown (the just-resumed handle is disposed before the closed-guard throw). + +**Teardown ORDER is load-bearing for durability**, and the implementation folds the session lifecycle into the agent's SINGLE composite cordis effect (`SessionStore.prepare`/`enter`/`announce`, replacing a sibling-effect split). A fiber unload disposes sibling effects concurrently (`Promise.all`), which would race removing the session store's append publication hooks against the loop's closing `session/flush` and drop the closing `turn/end`; inside one effect the disposers run as an ordered LIFO chain (loop stopped + `await agent.done` BEFORE the session detaches), so the loop's final flush is captured on BOTH the handle's `dispose()` and a fiber unload. The contained `agent/disposed` and `session/disposed` notifications cannot reject the chain or skip later teardown. + +### 3. Bash owner token in the seam + +Background-task ownership moved from a `tool-bash` plugin-local `Map<string, Agent>` into the executor. `BashExecRequest` gains an optional `owner?: string`; the resolved `BashExecSpec` carries it as required-but-nullable `owner: string | undefined` (a forgotten owner is a visible `undefined`, never a silently-absent property). The executor stores the token on its task and exposes it via a new `BashExecutor.ownerOf(id): string | undefined` seam (NOT on the public `BashTask` — one read path, no redundant API). `tool-bash` deletes its `Map` entirely: it stamps `exec.agent?.id` (the shared registry/session id) as the owner at `start`, and `bash_output`/`bash_kill` compare `ctx.bash.ownerOf(id)` to the caller's token with `!== undefined` semantics (an empty-string token is still a real owner). The completion notice finds the live agent by scanning `ctx.get('agents')?.list()` for `agent.id === ownerToken` (read via `ctx.get` — `onTaskDone` runs on the bash fiber, a foreign fiber, where the `ctx.agents` proxy would throw). Because ownership now lives on the task in the executor (disposed with the `dsh-bash` fiber), it SURVIVES a `tool-bash` HMR reload — closing the old `XXX(tool-bash-owner-hmr)` gap. (The `onTaskDone` listener is still effect-scoped to `tool-bash`'s `apply`, so a completion landing during the reload gap still drops its one notice — the pre-existing reload-gap drop — but the ownership fence itself is HMR-proof.) + +## Verification + +These invariants hold and are pinned by tests: + +- ACP disconnect/session close leaves no registered agent AND no session-store entry for that session, even when `session/load` races teardown. +- `session/cancel` before a queued prompt starts prevents that prompt from running and cannot batch the next prompt into the cancelled turn. +- A `tool-bash` HMR reload does NOT make an existing background task readable or killable by a different session (ownership survives on the executor). +- Existing non-ACP demos still work without managing handles explicitly; config-created agents remain owned by the `AgentLoop` plugin fiber. + +## Session owner tokens are unique among live agents + +The bash owner-token comparison relies on the shared `Agent.id`/`SessionId` being unique among live agents.

The brand primitive lives in the dependency-free `dsh-brand` utility package precisely so `dsh-bash` can brand its ids by depending on it alone — it never pulls in `dsh-llm` (or `dsh-session`) just to reach `Branded`. Thread it through `BashTask.id`, the `BashExecutor` seam methods (`get`/`ownerOf`/`readOutput`/`kill`), the generation site in `dsh-bash-local` (brand the counter output once, at creation), and the `dsh-tool-bash` validate/access surface (`validateTaskId` returns a `BashTaskId`; `task_id` is branded at the tool boundary where the model's string arrives). + +- **Mint a distinct `OwnerToken` brand.** Add `OwnerToken = Branded<'OwnerToken'>` in `packages/bash/bash/src/types.ts`; type `BashExecRequest.owner` / `BashExecSpec.owner` / `BashExecutor.ownerOf` as `OwnerToken | undefined`.

Typing the seam's field as `SessionId` would import `dsh-session`'s vocabulary into a package that must not know what an owner token *means* — it would couple a generic execution backend to the session model and contradict the opaque-token design. A sandboxed or remote executor that replaces `dsh-bash-local` should not inherit a session dependency. The distinct `OwnerToken` brand keeps the seam decoupled: `dsh-bash` knows only "an owner is some opaque branded token," and the `dsh-tool-bash` consumer — which already decides the access policy — is the single boundary that casts its `SessionId` into an `OwnerToken`.

A `SessionId.parse()` / `isValid()` companion that throws on malformed input at boundaries is a genuine gap, but it is a *runtime-behavior* change with its own design (what is "malformed"? what do we do on failure?) and belongs in its own Agent Note, not bundled into this type-only pass. + +## Verification + +The landed invariants: `BashTaskId` and `OwnerToken` are defined in `dsh-bash` and threaded end-to-end (executor seam, the `dsh-bash-local` generation site, the `dsh-tool-bash` model-facing surface) with no `dsh-bash` dependency on `dsh-session`; no collection keyed by an in-scope branded id (`CallId`/`SessionId`/`BashTaskId`) is keyed by bare `string`; public method params and exported signatures keep the brand; and brands are constructed via the cast factory at each boundary where a raw string enters (provider call id, ACP session id, model-supplied `task_id`), never as scattered `as` casts. + +## Consequences + +- **Mechanical churn across two surfaces.** Propagating brands touches the bash seam (interface + impl + consumer) and the ACP session-id surface plus the persistence coordinator. The churn is broad but low-severity: a missed site is a compile error, not a silent bug. The change is observably type-only — no snapshot or e2e behavioral diff. It sits next to the [unified agent/session identity decision](../simplification/2026-06-20-unify-agent-and-session-id.md) because both touch the session-id / owner-token boundary; `OwnerToken` stays distinct from the unified id for the decoupling reason above. +- **Brands do not validate.** A brand is a confusability guard, not a correctness proof: a *wrong* session id that is still a well-formed string passes the type checker exactly as before. This Agent Note does not close that gap (see Out of scope) — it only stops the *category* error of passing the wrong *kind* of id. +- **The "where to stop" line stays a judgment call.** Branding `BashTaskId` but not `ToolName`, `OwnerToken` but not `ModelId`, is a taste call about which strings "could plausibly be confused."

A producer calls `ctx.tasks.start()` with a kind, label, optional owning `Agent`, and a `run()` function. The runtime completes all failable preflight work before calling `run()` and invokes it once. After `run()` returns hooks, registration commits without another failable step; a producer cannot start work that lacks a collectable task id. + +The producer hooks define three responsibilities: + +- `cancel(reason?)` synchronously requests termination, is idempotent, and must cause `done` to settle. +- `done` never rejects and settles only after the producer has released the task's resources. +- Optional `readOutput()` returns the next consuming output delta. Omitting it declares a final-output task whose terminal result comes from `TaskOutcome.output`. + +Statuses are `running`, `stopping`, `completed`, `killed`, and `failed`. Producer-specific information such as an exit code or stop reason belongs in `detail`; the registry does not interpret it. Task kinds form a merge-extensible string union, and task ids are branded and generated as `<kind>-N`, with a counter per kind. + +The runtime attaches one continuation to `done`, records the first terminal outcome, resolves waiters, and invokes completion listeners with per-listener error containment. First-wins settlement matters during teardown: if `cancel` throws, the runtime force-fails the record and warns that work may be orphaned rather than waiting forever for a promise that may never settle. A later producer outcome cannot overwrite that diagnosis or notify twice. A `cancel` that returns without eventually settling `done` still blocks teardown because the runtime cannot distinguish it from a slow, valid stop. + +Task registrations are not effects of the producer tool fiber. Reloading a tool or control-surface plugin therefore does not kill work owned by an agent and backend. The task service's own disposal cancels all live tasks and awaits contract-compliant producers. + +## Authorization and owner lifecycle + +Task ids are runtime-global and predictable, so every access is authorized by the registry. `get`, `read`, `wait`, and `kill` accept the calling `Agent`; `list` returns only tasks visible to that caller. An owned task is accessible only to the exact owning session. Unowned tasks are open to non-agent callers and die with the task service. + +The snapshot stores the owner's branded `SessionId` for authorization, while lifecycle operations retain the exact live `Agent` instance. These identities serve different purposes: session equality grants access, but exact object identity selects cleanup and completion delivery. Reusing an agent or session id cannot redirect an old scope's cleanup or notices to a replacement. + +The first task for an owner attaches one asynchronous effect to `owner.ctx`. Agent-scope disposal cancels that owner's live tasks, awaits their terminal records, and removes their snapshots. This effect survives producer reloads and joins the agent's existing quiescence boundary. The task service retains the effect disposer so service reload can detach callbacks from still-live agent scopes after global teardown. + +For contract-compliant producers, `AgentHandle.dispose()` resolves only after owned background work has stopped. Work intended to outlive an agent must be started unowned; survival across runtime restarts requires a separate durable-job design. + +## Service surface + +`TaskService` provides: + +- `start(spec)` for preflighted, atomic registration. +- `get(id, caller?)` and `list(caller?)` for non-consuming snapshots. +- `read(id, caller?)` for a consuming stream delta or an idempotent final result. +- `kill(id, caller?, reason?)` for cancellation. +- `wait(id, timeoutMs, caller?, signal?)` for bounded terminal waiting. +- `onTaskDone(listener)` for effect-scoped observation with exact-owner delivery and listener containment. +- `attachSurface(name)` for the control-surface availability fence. + +`wait` returns the terminal snapshot when the task settles or the live snapshot when its timeout expires. Aborting a wait cancels only that wait. If settlement has already assigned terminal delivery to the waiter, the terminal snapshot still wins. Waiters unregister synchronously on abort so a same-tick settlement cannot suppress a completion notice on behalf of a reader that receives nothing. + +A producer loaded without any control surface would let callers start work they cannot collect or stop. `dsh-tool-tasks` therefore calls `attachSurface()` for its lifetime, and `start()` fails before producer execution when no surface is attached. This check occurs at start rather than plugin load because sibling plugins may activate concurrently. Custom non-model surfaces can attach themselves without teaching the registry tool names. + +## Model-facing control surface + +`dsh-tool-tasks` registers three kind-independent tools with generic ACP cards: + +- `task_output(task_id, wait?, timeout_ms?)` reads output and always appends `[status: ...]`. Stream tasks return only output since the previous read; final-output tasks return their result after settlement. Reads are non-blocking unless `wait: true`, whose timeout is defaulted and capped by plugin config. A wait timeout reports the still-running status and does not stop the task. +- `task_list()` returns caller-visible tasks as `<id> [<kind>] <status> — <label>`, or `(no background tasks)`. +- `task_kill(task_id, reason?)` requests cancellation immediately. The optional logged reason is forwarded to the producer. Terminal tasks report their existing status; a throwing producer cancel fails the call and leaves the task running. + +Stream reads share one task-scoped consuming cursor because the owning model is the intended reader. A UI or multiple independent readers need a separate non-consuming observation API; sharing this cursor would let readers consume one another's output. + +The system prompt tells the model to retain task ids, continue independent work instead of busy-polling or duplicating a running task, collect relevant tasks before its final answer, and kill work that no longer matters. Completion injects a logged `context/message` into the exact owner's session; it becomes durable context for the next request but does not wake an idle agent. + +The runtime marks a terminal task `reported` when a read or wait delivers it, when a live waiter has claimed delivery at settlement, or when the model explicitly kills it. Reported tasks do not inject redundant completion notices. Listener failures are logged independently, do not stop later listeners, and are not awaited by waiters or teardown. + +## Producer opt-in + +Each producer owns whether its schema exposes `run_in_background` through defaulted config. `dsh-tool-bash` and each `dsh-tool-subagent` instance use `enableRunInBackground`, defaulting to true. A disabled instance omits the parameter and also rejects a forced background argument at execution because the generic argument validator permits undeclared keys. Schema omission advertises the capability; the execution check enforces it. + +`ctx.tasks` does not rewrite producer schemas. A bundle forwards configuration only for producers it owns. If a background call reaches `start()` without an attached surface, the runtime fence fails before execution. + +## Producer integrations + +The bash seam exposes `resolve`, `run`, and `start`. `start(spec)` returns a `BashProcess` with incremental reads, cancellation, exit facts, and a non-rejecting quiescence promise. The local executor retains live handles only so its own disposal can kill and join processes. Foreground callers continue to use `resolve` and `run` directly. + +For background bash, `dsh-tool-bash` registers the calling agent as owner. Its hooks map `kill()` to cancellation, `done` to a completed or killed `TaskOutcome`, and `readOutput()` to the process's bounded incremental output plus spill and sandbox notices. Generic task tools own ids, status lines, listing, waiting, and completion notices. + +For background subagents, `dsh-tool-subagent` creates a task-owned `AbortController` and begins provider startup inside the task starter. Cancellation aborts the same signal before or after provider readiness. `done` awaits both the child result and child disposal, maps completed output to a final result, maps abort to `killed`, and maps other stop reasons or infrastructure failures to `failed`. Intermediate child history remains in the child session and is not exposed through `readOutput()`. + +## Alternatives considered + +### Per-capability control tools + +Separate bash and subagent output/stop tools duplicate ids, isolation, cleanup, notification, and guidance while increasing the model's schema and protocol burden.

Foreground-to-background promotion requires a user interaction contract the SDK does not prescribe. Starts, reads, and notices are already logged as tool and context events, so dedicated task session events would duplicate model-visible facts. + +## Testing + +Unit coverage pins preflight atomicity, per-kind ids, stream and final reads, wait timeout and abort races, cancellation, first-wins settlement, listener containment, notice suppression, owner isolation, stale owner instances, owner cleanup, service teardown, and the no-surface fence.

Snapshot coverage pins the control-tool schemas and prompt guidance. + +## Consequences + +Bash commands and subagents share one id vocabulary, listing, notice format, prompt habit, and set of control tools. New long-running producers implement execution hooks instead of another registry and tool family. The [tool cookbook](../../../../docs/cookbook/adding-a-tool.md) points producers to this contract. + +Owned background bash now stops with its agent instead of surviving it. Background processes have no executor timeout; callers must kill irrelevant work or rely on owner/service disposal. Stream reads support one consuming reader, completion notices do not wake idle agents, and a producer that returns from `cancel` without settling `done` can still stall teardown.

The local backend renders it as a filesystem path; a remote or database backend can render a URI, key, or command token. Consumers treat it as opaque and render it with `retrievalHint` instead of assuming `read` is always the right retrieval mechanism. `SpillOwner.sessionId` is the save-time storage namespace: forked sessions inherit existing spill locators from the seeded log without copying or re-owning them, and new spills after the fork use the child session id. A retention-period cleanup may expire old locators with other old session artifacts; the spill seam does not define a per-session cleanup policy. + +`dsh-spill-local` owns only storage details: session-scoped directory selection, safe names, path-traversal protection, the write, and returning `{ locator, bytes, retrievalHint }`. It does not own retention policy, tool-result replacement, search, or file inspection. Files land at `<root>/session-<hash>/<random>-<safeName>`, where `root` is a configured path or a lazily-created private (0700) per-process temp dir, the session subdir is a short `sha256(sessionId)` prefix, and the leaf is a random hex prefix plus the caller's `suggestedName` sanitized to one path segment (mirrors the JSONL backend's `encodeSegment`). The write is `open(path, 'wx', 0o600)` — exclusive and owner-only, so a planted symlink cannot redirect it. The locator is the path, and the retrieval hint tells the model it can use `read` or `grep` on that path. + +### Spill policy + +`dsh-spill-policy` is a `tools/post-execute` result transformer with one configuration knob: + +```ts ignore-check +interface Config { + /** Omitted means no automatic spill policy. Present means apply to oversized plain text tool results. */ + maxInlineBytes?: number +} +``` + +When `maxInlineBytes` is omitted the plugin registers nothing (a true no-op). When set, it applies a default policy to final plain-text tool results: + +1. Let the tool run normally, delegating via `next()` so a downstream listener settles the result first. +2. Flatten the accepted final `ContentBlock[]` only when it is entirely plain text; a result with any non-text block is left untouched. +3. If its UTF-8 byte size is at or below `maxInlineBytes`, leave it unchanged. +4. If it is larger, call `ctx.spillStore.saveText()` with the full final text. +5. Replace the model-facing result with a retained head/tail preview plus the spill reference. + +The preview is an implementation default owned by the policy: a head/tail split of `maxInlineBytes` via the retention library's `TextRetainer`. Future config can expose preview sizing only after a second deployment needs it. + +The replacement text is intentionally generic because the policy only knows the final formatted tool result, not the tool's internal resource: + +```text +<retained preview> + +(Omitted N bytes. Full formatted result stored at: /.../session-.../....txt. Use read with offset/limit, or grep this path to search within it.) +``` + +If `ctx.spillStore.saveText()` fails (permissions, ENOSPC, backend unavailable), or the call has no session owner, or no backend is loaded, the plugin logs the reason and returns the original result unchanged. Spill failure never turns a successful tool call into an `isError` result or hides the inline result. + +The policy skips `read` to avoid a circular `read -> spill file -> read again` loop. Additional opt-out configuration is deferred until a real second tool needs it. + +## Showcase: web_fetch + +`web_fetch` is the first showcase because it returns a naturally large text result and needs no tool-specific spill code. The tool is ordinary: + +```ts ignore-check +ctx.tools.register(defineTool({ + name: 'web_fetch', + async execute(args, exec) { + const result = await ctx.web.fetch({ url: args.url }, exec.signal ? { signal: exec.signal } : undefined) + return [{ type: 'text', text: formatFetchOutput(result) }] + }, +})) +``` + +With `dsh-spill-policy` configured, a large formatted fetch result is automatically retained and spilled. A deployment demonstrates the behavior by setting the provider resource cap higher than the policy cap: + +```yaml +- id: web-fetch-local + name: '@deepseek-ai/dsh-web-fetch-local' + config: + maxBodyChars: 500000 + +- id: spill-local + name: '@deepseek-ai/dsh-spill-local' + +- id: spill-policy + name: '@deepseek-ai/dsh-spill-policy' + config: + maxInlineBytes: 50000 +``` + +This separation is important. `web-fetch-local` still owns resource caps (`maxResponseBytes`, `maxBodyChars`) to protect network, memory, and decoding work. `spill-policy` owns only the model-facing context cap after the result already exists. If the provider already returned `truncated: true`, the spill file contains the full formatted result the tool returned, not the full original webpage; the policy does not claim otherwise. + +## Relationship to retention and early spill + +Retention is separate from spill storage: + +- `@deepseek-ai/dsh-retention` owns preview mechanics (`TextRetainer`, `ItemRetainer`, and omitted metadata). +- `@deepseek-ai/dsh-spill` owns saving final text and returning a locator plus retrieval hint. +- `@deepseek-ai/dsh-spill-policy` applies the default final-result policy in the tool pipeline, composing the two. + +The final-result policy cannot replace tool-owned early spill. Some useful content is not present in final `ToolExecutionResult.content`: + +- `bash` final output is already a tail plus a temp spill path; the complete stdout/stderr streams live in executor files. +- `subagent` final output is the child final answer, not the child rollout. +- Future tools may produce runtime artifacts that are never represented by their final `ToolExecutionResult.content`. + +Those cases can consume `ctx.spillStore` directly in later work. They are not part of the first showcase. + +## Non-goals + +- No new model-facing `artifact_read` or `artifact_search` tool in v1. +- No per-tool retention configuration in v1. +- No model-facing timeout/truncation arguments. +- No migration of `read` output into spill files. +- No replacement for provider/resource caps such as `web-fetch-local.maxBodyChars`. +- No bash temp-file normalization or subagent rollout capture in the first cut. + +## Deferred + +- `saveFile()` / `linkOrCopy` for existing executor spill files, needed for bash normalization. +- Tool-owned spill for subagent rollouts (`await run.result`, read in-process child session before `run.dispose()`, save JSONL). +- Per-tool opt-out or per-tool policy declarations if the built-in `read` skip is insufficient. +- Remote or database storage backends for ACP or remote environments where a local path is not meaningful. +- Cleanup and retention policy for old spill files, likely tied to session cleanup. + +## Testing + +- `dsh-spill` unit tests pin the seam contract: registration as `ctx.spillStore`, one-implementation-per-context, and disposal release. +- `dsh-spill-local` unit tests cover `saveText`, `encodeSegment` sanitization (separators/tilde/whole-segment dots/empty), the session-hash directory, owner-only permissions, distinct paths per save, the configured/private root, and a storage-failure rejection. +- `dsh-spill-policy` unit tests drive real tools through `ctx.tools.execute`: disabled-mode no-op, oversized-text replacement, small/non-text passthrough, `read` skip, best-effort fallback (save failure / no backend / no owner), and downstream-composition (bounding a replaced result, preserving `additionalContexts`). +- `dsh-tool-web` integration drives `web_fetch` through `ctx.tools.execute` with the real `spill-local` backend + policy, proving the model-facing text changes only by the deliberate spill notice while the spill file holds the full formatted result. +- The `repl-agent` example loads `spill-local` + `spill-policy`, so its keyless Loader smoke exercises the real load path (the namespace-plugin export shape + `inject`). + +## Consequences + +The default policy only sees final formatted text. It cannot preserve provider-internal content that was already capped or runtime artifacts that were never part of the result. This is acceptable for the first cut because the showcase is final-result spill, not early spill; tool-owned early spill remains deferred work. + +Returning real paths from the local backend keeps v1 simple and matches proven agent-tool behavior, while the seam itself only promises an opaque locator plus retrieval hint so remote backends can return non-file locators. + +The local-backend value proposition depends on the existing `read`/`grep` tools being able to inspect the returned local path, even when the spill directory is outside the session cwd. That holds today because the filesystem policy records observations and write guards but does not confine reads to the workspace. A future workspace-confinement policy must either allow local spill paths explicitly or use a non-file spill backend whose retrieval hint points at a supported reader. + +**Snapshot gap.** No ACP snapshot scenario covers the transcript-visible `web_fetch` spill notice yet. The ACP snapshot harness replays keyless and cannot hit the live web, and a `web_fetch` spill requires a real over-cap HTTP body; a deterministic scenario would need a seeded loopback fetch target the replay tree does not currently wire (the examples do not load `tool-web` at all). The behavior is covered instead by the `dsh-tool-web` integration test against a loopback server. Closing the gap is follow-up work: wire `tool-web` + a seeded fetch target into the ACP example, then record a `web-fetch-spill` scenario. + +The policy can become too large if it starts owning tool-specific semantics. It stays narrow: plain-text final results only. Tool-owned early spill remains future work. + +## Alternatives considered + +**Require each tool to opt in with a retention declaration.** Rejected for v1: the goal is a default behavior similar to Claude Code's generic tool-result persistence. A single `maxInlineBytes` deployment knob is enough to prove the shape. + +**Make `tool-results` a broad tool-result platform.** Rejected: a broad package name invites retention policy, result replacement, preview wording, search, and early spill into one seam. The shared storage part is smaller: save text and return a locator plus retrieval hint. + +**Use `ctx.fs.writeText` or the model-facing `write` tool.** Rejected: workspace filesystem writes carry project-file semantics, write/edit policy, observation state, and user-facing side effects. Spill files are runtime artifacts, not model-authored workspace edits. The existing `read` tool may inspect them later, but creation belongs to the runtime spill seam. + +**Let `web-fetch-local` fetch without caps and rely on spill-policy.** Rejected: spill-policy runs after the final tool result exists and cannot protect network, memory, or decoding resources. Provider resource caps stay mandatory. + +**Merge retention into spill.** Rejected: retention and spill have different responsibilities. `TextRetainer`/`ItemRetainer` decide what preview is kept and what was omitted; spill storage only saves the final text the policy asks it to save. diff --git a/.agents/notes/implemented/architecture/2026-07-10-after-call-compaction-pressure-and-overflow-recovery.i18n.yaml b/.agents/notes/implemented/architecture/2026-07-10-after-call-compaction-pressure-and-overflow-recovery.i18n.yaml new file mode 100644 index 0000000000..a6344d276f --- /dev/null +++ b/.agents/notes/implemented/architecture/2026-07-10-after-call-compaction-pressure-and-overflow-recovery.i18n.yaml @@ -0,0 +1,6 @@ +# Bilingual-pair consistency record (docs/i18n/README.md): the git blob hash of each +# side as of the last confirmed-consistent state.

It does not fall back to `AgentOptions.model` for automatic pressure. A headerless session has no completed routed request to assess and produces no work; any durable non-empty model name uses the same estimator. Operational measurement or summarization failures warn and continue with full history. + +### Request recovery is limited to the final model boundary + +`RequestError`, `RequestErrorDecision`, and the `agent/request-error` waterfall represent failures after the final adapter has been selected. Each returned stream handle owns a private failure set that preserves the original thrown error identity across dispatch, iterator construction, and iteration without leaking nested-call provenance into an outer call. Terminal in-band `error` or `aborted` finishes enter the same path. Prompt assembly, request middleware, request logging, result processing, tools, post-step listeners, and cleanup remain ordinary failures. + +The failed step closes before recovery runs. A retry opens the next numbered step and rebuilds the request from the durable log; consecutive recovery attempts reset only after a successful provider request. Both DeepSeek adapters normalize recognized provider context-limit failures to `CONTEXT_WINDOW_EXCEEDED`. + +If cancellation lands after assistant tool calls are durable but before all calls dispatch, the loop records a synthetic `tool/call` and aborted `tool/result` pair for every undispatched call before following the normal abort path.

The same singleton meter owns range pricing, provenance, shadowed token counts, and non-shrinking-summary rejection.

It chooses the maximal tool-balanced head range while leaving the newest indivisible unit, then attempts exactly one shrinking compaction under the same signal.

A backend returning a result without replacement cannot authorize retry. + +`maxOverflowRetries` is optional and defaults to `1`; `0` disables overflow recovery without disabling pressure. `auto: false` registers neither automatic listener.

With no later recovery, the loop reports the original provider error object and code. Cancellation or disposal remains authoritative even if recovery work completes concurrently. + +The default summarizer resolves explicit configuration, then the latest logged route, then agent options.

A plugin supplied a model list at Cordis startup, `LlmService` stored one adapter per listed string, and `GenerateOptions.model` selected the adapter and the provider model at once. This worked while both shipping adapters targeted the same two DeepSeek models, but it conflated two independent decisions: which upstream provider owns a request, and which model that provider should run. + +The conflation prevents a provider gateway from serving an open-ended model catalog. OpenRouter, for example, is one provider with many model ids, while a private OpenAI-compatible endpoint may add models without changing the Harness plugin tree. Every newly selected model currently needs to have been registered during plugin startup. The same model id can also exist at multiple providers, so model-only registration cannot state which provider the caller intended. + +`dsh-llm-pi-ai` exposed none of pi-ai's provider abstraction. It constructed an inline DeepSeek `openai-completions` model, applied DeepSeek-specific payload patches, and stamped every replayed assistant message as DeepSeek. pi-ai itself has a provider/model catalog, selects APIs such as `openai-responses`, `anthropic-messages`, and `google-generative-ai`, and preserves provider-specific response ids and reasoning/tool signatures for later turns. The Harness conversion dropped that provenance, so simply replacing the inline model with a catalog lookup would have made same-model replay and cross-provider handoff incomplete. + +The adapter configuration also assumes one DeepSeek API key and endpoint. A generic backend needs independent credentials and endpoint overrides per provider while leaving AWS, Google ADC, OAuth, and other ambient authentication mechanisms to pi-ai. + +## Decision + +### Provider is the adapter registration key + +`GenerateOptions` and `LlmCallConfig` carry `provider: string` beside `model: string`; `AgentOptions` carries the corresponding optional creation field. A loop request is valid only after both values are non-empty, and both values are part of the logged request header. `agent/request` may return a replacement pair on any step, so a session can switch providers and models without changing the Cordis plugin lifecycle. + +`LlmService` registers and resolves adapters by provider. `registerAdapter(providers, adapter)` checks the entire provider list before mutating the registry, rejects a duplicate with `DUPLICATE_ADAPTER`, and disposes the whole registration as one effect. Model ids are not registration keys; the selected adapter still validates or forwards them. The later [LLM catalog and ACP selection Agent Note](2026-07-15-llm-model-catalog-and-acp-selection.md) added advisory `listProviders()` / `listModels()` discovery without turning model membership into request validation. + +A provider has exactly one adapter owner in a Cordis context. `dsh-llm-deepseek` registers `deepseek`; `dsh-llm-pi-ai` may also register `deepseek`, but loading both owners is a configuration error rather than an ordering rule or fallback. A deployment that wants the hand-rolled DeepSeek implementation excludes `deepseek` from the pi-ai profiles. A deployment that wants pi-ai's DeepSeek implementation does not mount `dsh-llm-deepseek`. + +`dsh-llm-deepseek` removes its model registration list and accepts any model string routed through provider `deepseek`. Its request serialization, `/chat/completions` endpoint, thinking options, SSE parsing, and error behavior remain unchanged; `options.model` is still sent verbatim. + +### Explicit pi-ai provider profiles + +`dsh-llm-pi-ai` takes one non-empty list of provider profiles. Provider names must be unique within the list and present in pi-ai's `getProviders()` result. Each profile contains the provider name plus optional `apiKey`, `baseURL`, headers, reasoning level and budgets, cache retention, transport, timeouts, and retry settings. Credentials are never global: an explicit key applies only to its profile, while an absent key lets pi-ai resolve its standard environment variable, OAuth token, AWS credential chain, Google ADC, or other provider-native ambient authentication. An explicitly empty key is invalid configuration rather than an environment fallback. + +The plugin registers all configured provider names against one `PiAiAdapter` in one all-or-nothing call. A request uses its provider to select the matching profile and finds its model in `getModels(provider)` to obtain the catalog descriptor. An unknown provider fails at plugin load; an unknown model fails before network I/O with `UNKNOWN_MODEL`. The catalog object is never mutated. When a profile supplies `baseURL`, the adapter clones the selected descriptor and overrides only `baseUrl`, so a private endpoint can retain pi-ai's API, capabilities, compatibility flags, context limits, and reasoning map. The private endpoint must implement the selected provider's protocol, and the model id must still exist in the installed pi-ai catalog. + +The adapter calls pi-ai's `streamSimple()` so each catalog model chooses its registered API implementation, including OpenAI Responses instead of Chat Completions where the descriptor says `openai-responses`. Harness temperature, maximum tokens, signal, session id, and the profile's common stream options flow through directly. Profile headers merge with the mandatory Harness attribution headers, with Harness attribution winning its reserved names. The adapter no longer maintains DeepSeek-specific payload rewrites or a provider-protocol matrix. + +pi-ai's common stream options do not expose stop sequences. `dsh-llm-pi-ai` rejects a defined Harness `stop` option with `UNSUPPORTED_OPTION` rather than silently ignoring it or growing a second provider-specific payload implementation. `dsh-llm-deepseek` continues to support `stop` through its native request serializer. + +### Durable assistant provenance and replay state + +Assistant messages carry provider-neutral provenance containing the request's `provider` and `model`, plus an optional JSON-serializable adapter replay state. A successful `assistant/message` session event records this provenance and `deriveMessages()` returns it with the assistant message. User, system, context, and tool-result messages carry no assistant provenance. The provider/model fields are authoritative loop data; an adapter owns only its opaque replay-state payload. + +A terminal successful `finish` chunk may carry replay state, and `BlockAssembler` retains it alongside usage and finish reason. The loop attaches it to the assistant provenance only when the post-`agent/step-result` content is structurally equal to the assembled provider output. A listener that rewrites content keeps the provider/model provenance but loses the now-stale replay state. Error and aborted responses do not produce a normal assistant message and therefore do not enter future model history. + +The pi-ai replay state is a versioned, minimal projection of its successful `AssistantMessage`: source API/provider/model, response id/model, stop reason, and index-aligned text, thinking, and tool-call signatures. It does not duplicate text or tool arguments already carried by Harness content blocks, and it omits diagnostics, timestamps, usage, and errors. On a later request, `LlmService` gives replay state to the target adapter only when the historical provider and target provider are currently owned by the same adapter instance. That adapter combines the logged Harness content with replay state when it can restore the historical response, and owns any required cross-model or cross-provider conversion. An adapter receiving replay state with an unknown version or mismatched block shape fails explicitly; a different adapter receives only provider-neutral content and provenance. + +This state is model-visible replay input and therefore follows the existing [reconstructable-request rule](2026-07-05-reconstructable-requests.md): it is present in both the terminal `finish` chunk and the assembled `assistant/message` provenance that drives derivation. Resume and fork preserve it verbatim. Compaction that shadows the assistant message also removes its replay state from the active surface; the summary is ordinary provider-neutral content. + +### Propagate the target through every request producer + +Every model-selection surface carries provider and model together: declarative agents, ACP and stdio app config, the JSON-RPC initialize request, subagent overrides and inheritance, workflow child overrides, and direct compaction summarization. Subagents inherit both fields from their parent before applying request overrides. The system-prompt variable set gains `provider` beside `model`. + +Compaction configuration gains `summarizationProvider` beside `summarizationModel`. Both are empty to inherit, or both are non-empty to select an explicit target; a half-configured pair fails load. Inheritance uses the last logged request target when one exists and falls back to the agent's creation options. `compact/summary` records both fields with the existing model-call envelope. + +The JSON-RPC runtime receives provider and model explicitly. Its convenience fallback mounts `dsh-llm-deepseek` only for provider `deepseek` when that provider has no registered owner; other missing providers fail without guessing an adapter. + +The on-disk session format remains the pre-release pinned version `0`, with no compatibility promise. Seed/load validation rejects request headers lacking provider and assistant messages lacking required provenance instead of accepting an old shape that can no longer reconstruct the request. + +## Alternatives considered + +**Keep model names as registry keys and add wildcard adapters.** A wildcard introduces fallback ordering between exact registrations and catch-all plugins, makes duplicate ownership dependent on listener order, and still cannot distinguish the same model id at two providers without another convention. + +**Encode provider and model into one string.** Values such as OpenRouter's `openai/gpt-*` already contain provider-like prefixes and slashes. A delimiter convention would leak routing syntax into every model selector and require escaping rules; two explicit fields are unambiguous and independently loggable. + +**Add `backend + provider + model`.** A backend key would allow `dsh-llm-deepseek` and pi-ai's DeepSeek implementation to coexist and switch per request. The accepted deployment rule is instead one adapter owner per provider: implementations of the same upstream are alternatives selected by plugin composition. A third routing dimension would burden every request and configuration for a capability with no current consumer. + +**Let `dsh-llm-pi-ai` automatically register every pi-ai provider.** This would claim ambient credentials and provider names the deployment never intended to expose, and would conflict with native adapters such as `dsh-llm-deepseek`. Explicit profiles make capability and credential scope reviewable. + +**Mount one pi-ai plugin instance per provider.** Separate instances isolate config but repeat plugin declarations and cannot make profile registration atomic. One adapter already receives provider on every request, so a validated profile map is the smaller lifecycle surface. + +**Accept arbitrary inline pi-ai model descriptors.** This would support catalog-external private model ids, but it exposes pi-ai's model and compatibility schema as Harness configuration and makes the adapter responsible for validating protocol-specific combinations. The first version supports custom endpoints by overriding `baseURL` on catalog models; custom descriptors require a separate decision after a real catalog-external deployment is identified. + +## Consequences + +- Provider names are deployment-wide route ownership keys: two providers may use the same model string, but mounting two adapters for one provider fails at load instead of creating fallback order. +- Model selection no longer changes the Cordis plugin graph. Catalog-backed adapters can accept any installed catalog model selected after startup, while the native DeepSeek adapter forwards arbitrary DeepSeek model ids. +- A custom `baseURL` preserves the selected catalog model's protocol and capabilities; it does not make catalog-external model ids valid. Private endpoints must implement that catalog entry's protocol. +- pi-ai credentials and transport knobs are scoped per provider profile. An omitted key delegates to pi-ai ambient authentication, while an explicitly empty key is invalid. +- `dsh-llm-pi-ai` rejects stop sequences because pi-ai's common stream API cannot express them; the native DeepSeek adapter retains its stop support. +- Replay state is portable only within the adapter instance that owns both the historical and target providers. Cross-provider and cross-model restoration is an adapter responsibility, and another adapter receives provider-neutral history without the opaque state. +- Current pre-release session JSONL requires provider/model request headers and assistant provenance. Older shapes remain version `0` but are rejected rather than migrated. + +## Testing + +- Unit coverage exercises registry conflicts, request reconstruction, session validation, profile resolution, option forwarding, native API selection including OpenAI Responses, conversion, replay validation, error mapping, cancellation, content rewrites, and same-instance versus different-instance replay dispatch. +- Keyless loop/session tests and ACP snapshots exercise durable provider/model metadata, resume and fork propagation, workflow/subagent overrides, and unchanged user-visible transcripts; the key-gated DeepSeek e2e retains real provider streaming and tool follow-up coverage. +- Public JSDoc, package READMEs, architecture and core-data-structure docs, generated catalogs, examples, session fixtures, and Python SDK pairs use provider/model targets consistently and are checked by the repository documentation and type-equivalence gates. + +## Risks + +This is a repo-wide pre-release API break: model-only request construction, adapter registration, app protocols, fixtures, and persisted version-0 event shapes all change together, with no compatibility aliases. The provider exclusivity rule deliberately prevents two implementations of the same upstream from coexisting in one context. A pi-ai dependency update can change the accepted provider/model catalog, so the lockfile and adapter e2e matrix define the tested set. Custom `baseURL` endpoints inherit the chosen catalog model's protocol assumptions and cannot repair an incompatible proxy. Catalog-external model descriptors and multimodal content remain unsupported. pi-ai replay state may contain opaque encrypted reasoning signatures; it is persisted because the provider requires it for continuity, but it is never rendered or logged outside the existing session record. diff --git a/.agents/notes/implemented/architecture/2026-07-14-provider-routed-llm-adapters.zh.md

A Cordis `Context` selects services, registration ownership, and lifetime; `agent.ctx` is the flat registration scope owned by one live Agent. Agent and Session identity instead describe the subject of an asynchronous operation. Changing a root `ctx.agent` to mean “whichever Agent is running” would conflate those meanings and fail when one process drives Agents concurrently. + +Deep process-local infrastructure sometimes needs a trusted initiating Agent below explicit loop, tool, and request parameters—for example, a host-aware transport, tracing helper, logger, or gateway client. Requiring every private helper to forward `agent` adds repetition, while a process-global mutable slot is incorrect across `await`. Model-visible arguments are unsuitable because a model must not choose a trusted Session or routing header. The carrier belongs to the Agent service rather than optional model-visible context. + +## Decision + +The mandatory `ctx.agents` service uses Node `AsyncLocalStorage` to carry the initiating Agent. It stores the exact `Agent` directly rather than introducing a one-field frame; a separate private run token records nested boundary lineage only for teardown bookkeeping and carries no identity. The [core-data catalog](../../../../docs/core-data-structures/core.md#initiating-agent) identifies the carried type. + +`currentInitiator()` reads optionally, `requireInitiator()` throws `no initiating agent is active`, and `withInitiator(agent, operation)` preserves the operation's exact synchronous value or Promise. `withoutInitiator(operation)` establishes a clearing boundary for work that must not inherit an Agent. Session remains derived as `agent.session`; turn, step, tool call, `signal`, model, `cwd`, sandbox, and authorization stay with their existing owners. + +`AgentLoop` already injects `ctx.agents` and wraps each concrete driver's complete `runLoop` lifetime in `agents.withInitiator(agent, ...)`. Its package-private loop, turn, step, and tool-call orchestration entries recover the exact Agent from `ctx.agents`, derive `agent.session` once, and let operation-local helpers capture it instead of forwarding the concrete driver or `Session` through shallow interfaces. A leaf helper keeps a narrow `Session` parameter when that is its actual interface rather than accepting a broader `Context` only for an ambient lookup. + +Concurrent drivers receive independent stores. A child driver's continuations carry the child, while the caller resumes in its prior store as soon as `withInitiator()` returns; active-run tracking keeps the returned Promise in the teardown drain until it settles. Creation, persistence load, and unpublished `setup(agentCtx)` remain outside the child's driver boundary: creation initiated by a parent runs under the parent identity, while `agentCtx.agent` explicitly identifies the child. + +Ambient identity does not replace explicit contracts. `ToolExecution.agent`, `AssembleContext.agent`, `GenerateOptions.sessionId`, task ownership, parent/child requests, `ctx.agent`, `agentCtx.agent`, approval and hook subjects, `cwd` selection, cancellation, worker/process messages, persistence records, and wire identity remain explicit. A remote boundary materializes the identity it needs into its typed request because ALS is process-local. + +`AgentRegistry` owns an ordered initiator lifecycle. Teardown first rejects new boundaries; removing `ctx.agents` then drains injected dependents such as AgentLoop, and the registry waits for active returned-Promise boundaries before calling `AsyncLocalStorage.disable()`. If a boundary's inherited async chain starts an owning Cordis fiber's unload, the private run-token lineage releases that nested boundary chain from the drain, which prevents teardown from waiting on itself while unrelated boundaries still drain. `currentInitiator()` and `requireInitiator()` remain usable through a retained in-flight service reference while the ordinary drain runs; after disposal, initiator methods throw `agent initiator scope is disposed`. Root Context disposal may start sibling fiber teardown concurrently, so active-boundary counting remains necessary in addition to Cordis dependency ordering. + +Initiator scope does not own detached work: registry drain tracks only the Promise returned by `withInitiator()` or `withoutInitiator()`. Asynchronous resources created inside a boundary inherit its store until they settle or ALS is disabled, so their owning seam must stop unreturned work explicitly. Agent-owned foreground work returns its lifetime and keeps its cancellation contract. Unrelated timers, queues, and deployment infrastructure start under `withoutInitiator(operation)`; queue, worker, process, and wire boundaries serialize identity rather than expecting ALS propagation. + +A host-aware transport may derive a deployment-owned header such as `X-Harness-Session-Id` from `ctx.agents.requireInitiator().session.id`; the header is absent from model-visible schema and arguments. No production MCP or Web transport adopts such a header in this decision. A test-double transport proves the trusted boundary without assigning host routing policy to an existing provider-neutral seam. + +This decision extends the [Agent registration-scope contract](2026-07-08-agent-scope-contexts.md) and its [runtime design](2026-07-12-agent-scope-runtime-design.md); it does not change their static `agent.ctx` meaning. + +## Verification + +Agent service tests pin optional and required reads, exact synchronous and cross-realm Promise identity, intrinsic Promise settlement observation, overlapping, nested, and cleared boundaries, restoration after throws or rejection, ordinary and reentrant drain ordering, and retained-reference errors. AgentLoop integration pins concurrent and nested drivers, agentless calls, AgentRegistry restart, root teardown, and package-private loop and tool scheduling through the ambient lookup. Composition, module-graph, build, and runtime-closure checks keep `ctx.agents` wired through the default bundle, SDK spine, Python runtime closure, and direct AgentLoop harnesses without another provider. + +A test-double host-aware transport derives `X-Harness-Session-Id` internally and verifies that tool schema and logged arguments contain no identity field. The service deliberately does not drain async work omitted from the Promise returned by the boundary operation; that work remains subject to its owner's explicit stop contract. + +## Alternatives considered + +**Pass Agent through every function.** Public, worker, process, persistence, and wire boundaries continue to do this, but requiring every process-local private helper to carry Agent adds repetitive forwarding without improving trust. ALS is confined to the asynchronous chain inside those explicit boundaries. + +**Make `ctx.agent` dynamic.** `ctx.agent` already means the static Agent associated with an Agent-scoped Cordis context. Changing the root meaning would mix registration and execution scopes and make concurrent behavior surprising. + +**Add a separate `ctx.agentExecution` service.** The carrier has no independent backend, configuration, or identity type: it stores the same `Agent` that `ctx.agents` already owns, and AgentLoop already depends on that service. A second mandatory provider would add package, composition, lifecycle, generated-catalog, and test-harness wiring without separating a real capability. + +**Store a named or complete runtime frame.** A one-field `{ agent }` frame only wraps the value, while Agent, Session, inbox, cancellation, turn, step, tool execution, and persistence already have authoritative owners. Adding more fields would create stale snapshots and another lifecycle; carrying `Agent` directly keeps the boundary named by its methods without duplicating state. + +**Include a step `AbortSignal`, `cwd`, sandbox, or authorization.** Their lifetimes and authority do not match the driver boundary, and their existing seams already pass them explicitly. Adding a control capability requires a separate decision and nested lifecycle contract. + +**Use a process-global `currentAgent`.** Concurrent Agents and subagents overwrite one another across awaited continuations, so a mutable global is correct only under a serialization guarantee the harness does not make. + +**Derive identity from model-visible arguments.** Model or user input cannot be trusted to select Session, tenant, or sandbox routing. + +**Add routing identity to every capability seam.** That spreads hosting concerns through provider-neutral APIs. A host-aware implementation owns its transport header while public boundaries remain explicit. + +## Consequences + +Deep infrastructure gains one trusted process-local initiating Agent without widening existing tool and capability requests. Concurrent and nested drivers isolate automatically, AgentLoop gains no additional mandatory service, and HMR/root disposal reaches quiescence before ALS is disabled. + +The dependency is implicit in function signatures and carries a capability-bearing Agent object. Consumers must restrict it to cross-cutting infrastructure, treat ambient presence as neither liveness nor authorization, and retain explicit cancellation and ownership checks. ALS also has an always-on propagation cost and does not cross worker, process, HTTP, or durable queue boundaries. + +The teardown design deliberately accepts Node's [Stability 1 (Experimental)](https://nodejs.org/api/async_context.html#asynclocalstoragedisable) `AsyncLocalStorage.disable()` dependency. Node requires `disable()` before an ALS instance can be garbage-collected, which matters when HMR replaces AgentRegistry-owned instances; the service state guard prevents a later boundary from re-entering the instance after disposal. + +The scope deliberately carries only the Agent, omitting turn, step, `signal`, `cwd`, sandbox, and authorization. A real consumer that cannot use existing explicit fields must justify any refinement separately; a stale copied field may at most mislabel telemetry, never grant control. diff --git

Each opaque option value encodes the full provider/model pair. Models are grouped by provider when multiple non-empty provider groups exist; a single group is flattened for clients that render simple selects better. + +The session's current target is added to the displayed options when its adapter omits it. This preserves custom DeepSeek and private-endpoint models while keeping the adapter catalog advisory. A target with an unregistered provider is not advertised, and a model-less agent remains available to another `agent/request` supplier. + +`session/set_config_option` accepts only values from the current catalog snapshot and updates a target reference owned by that ACP session. No global `LlmService` or `AgentOptions` state changes, so concurrent sessions may select different providers and models. The existing permission select remains independent, and every response returns the complete refreshed option state. + +### Prompt/request consistency and durability + +Agent setup installs scoped `system-prompt/assemble` and `agent/request` listeners. Prompt assembly snapshots the selected pair once per step, overwrites the assembled `provider` and `model` variables after downstream prompt listeners, and the request listener applies that same snapshot after downstream request listeners. A selection during asynchronous assembly therefore starts on the next step rather than splitting prompt text from routing. Other call-config fields remain untouched. + +The request header remains the durable source of truth. When a selected target is actually used, the existing full `request/header` snapshot records it. `session/load` initializes the ACP selection from the folded last request header before falling back to bridge config. A selection that is never used by a request is intentionally in-memory only because it never became model-visible state. + +ACP's experimental `providers/*` capability is not used. That draft surface configures provider base URLs, protocols, and headers, including secrets; it does not enumerate models and would give the UI authority to rewrite deployment-owned adapter configuration. + +## Alternatives considered + +**Return model strings only.** A model-only value loses the provider route and becomes ambiguous as soon as two providers expose the same id. + +**Make catalogs mandatory whitelists.** This conflicts with the hand-written adapter's arbitrary model pass-through and private deployments. The selected adapter already owns authoritative request validation. + +**Store selection in `AgentOptions` or `LlmService`.** Those are creation-wide or deployment-wide objects. Mutating them would couple concurrent ACP sessions and bypass the logged `agent/request` replacement path. + +**Persist a new model-selection session event immediately.** An unused UI selection has not affected a model request. Recording the existing request header when the target is consumed preserves the model-visible-if-and-only-if-logged rule without adding a second source of truth. + +**Use ACP `providers/*`.** That unstable API changes endpoint and authentication configuration rather than selecting a model for one session, and its lifecycle and secret-handling semantics do not match this feature. + +## Consequences + +- Any adapter can expose a dynamic model list without leaking provider-library types into the core seam. +- Catalog consumers must treat absence as “not advertised,” never “invalid request.” +- pi-ai-backed ACP deployments automatically inherit the installed pi-ai provider catalogs; hand-written DeepSeek deployments list known choices explicitly and retain arbitrary model support. +- ACP clients receive a standard stable model config option, with provider-aware values and per-session isolation. +- Request headers remain compatible with the provider-routed session shape; no new JSONL event or format version is required. +- A catalog read can be asynchronous.

A compaction backend, an overflow guard, or a future request-policy plugin can all need the same answer: how much of the configured context window does the durable request consume? Keeping that fold inside `dsh-compact-basic` duplicates replay logic, makes measurement unavailable without compaction, and encourages callers to reuse stale accounting. + +Provider usage is not a complete answer. It describes one successful call under one exact request envelope, while the current surface can grow, shrink, or be replaced afterward. Sessions also switch providers and models, old logs can lack chunk provenance, and usage fields separate input, cache-read, cache-write, output, and reasoning counts. A useful service therefore combines the latest exact anchor with conservative heuristic repricing and exposes the log revision consumed by each result. + +## Decision + +### One concrete LLM-family service + +`@deepseek-ai/dsh-token-meter` is one concrete package under `packages/llm/` and registers `ctx.tokenMeter`. It is not split into an interface and backend before a second implementation exists. `TokenMeterService` itself exposes `contextWindow`, `measure(session, requestHeader?)`, and `estimateMessage(message)`; consumers call the singleton service directly. + +The service has one `contextWindow`, defaulting to 128,000 tokens and configurable as a positive integer. Estimation uses a fixed four-characters-per-token heuristic plus structural overhead. There are no model profiles, density settings, tokenizer backends, or language-specific strategies. + +### Per-session replay folds + +Each session owns one isolated incremental fold. Active folds advance from `session/event`; every read catches up through the durable tail, so listener ordering, seeded sessions, and service reload do not change the answer. The fold tracks canonical full request-header snapshots, step boundaries, surface appends and replacements, assistant usage, and assistant-chunk provenance. A malformed next event fails transactionally and remains unread rather than partially mutating state. + +`measure(session, requestHeader?)` synchronizes the fold once and returns scalar pressure together with positional per-node prices. `totalTokens` remains request-and-response pressure; `surfaceTokens` is the surface-only heuristic total and equals the sum of `nodes[].tokens`. A `requestHeader` override changes pressure pricing only, while the surface fields always describe the current session. `estimateMessage(message)` applies the fixed heuristic without session state. Each result is one detached, deeply immutable snapshot carrying one `logRevision`. Every measurement clones the current nodes and is therefore O(surface). + +Provider usage is reused only when the measured canonical request envelope equals the latest successful-call anchor. Any provider, model, system, prefix, tool, or call-config change causes complete heuristic repricing. Surface changes remain a signed delta from a matching anchor, including negative values after a shrinking replacement. A later successful request replaces the earlier anchor, including across provider or model switches. + +Usage sums the disjoint input, cache-read, cache-write, and output buckets. Reasoning is not added a second time. Every successful model call records an `assistant/message`, including content-less and max-token calls, with its exact earlier chunk seqs. An explicit empty provenance list means a known empty provider stream; absent legacy provenance conservatively treats the durable assistant output as provider output. + +### Compact-basic consumes, but does not own, measurement + +`dsh-compact-basic` requires `ctx.tokenMeter`; `CompactService` gains no token methods or types. Configuration, the region transaction, and summarization stay in separate modules; the service registers automatic listeners itself, while `summarize()` remains its sole subclass hook. The singleton meter consistently prices pressure, retention, shadowed content, provenance, and non-shrinking-summary rejection. + +Automatic compaction uses one unified measurement for each threshold-and-retention decision. The region transaction measures after appending its durable `compact/start` lock and again after asynchronous summarization; any intervening durable append changes `logRevision` and prevents replacement. + +Compact policy has service-wide defaults: threshold ratio `0.8`, retained tail `floor(contextWindow × 0.16)`, `summarizationProvider: ''`, `summarizationModel: ''`, `maxTokens: 8192`, `compactionRetries: 1`, `maxOverflowRetries: 1`, and `auto: true`. Top-level `thresholdRatio` and `retainTokens` override the pressure policy; retention must remain below the resulting threshold. The summarization provider and model must both be set or both be empty; an empty pair resolves the latest logged request target, then the `AgentOptions` pair. + +Automatic pressure runs at `agent/post-step` and measures the canonical durable envelope produced under the provider/model actually selected by `agent/request`. A headerless session has no completed routed request to assess and produces no work; any routed target can use the singleton estimator. Canonical overflow recovery uses the same measurement for forced range selection and retries only after a proven surface replacement. + +## Testing + +Unit tests cover fixed estimation, envelope invalidation and anchor replacement, replay boundaries, immutable snapshots, routed pressure, convergence, overflow generation proof, and rollback.

The model cannot compose tools — loop over a result set, branch on an intermediate value, fan out, post-process — without a full model round-trip per call, and each round-trip drags the entire intermediate result back into context whether the model needs it or not. Cloudflare's [Code Mode](https://blog.cloudflare.com/code-mode/) proposes an alternative grounded in a simple observation: LLMs are better at writing code than at emitting tool calls, because they have seen millions of lines of real code and comparatively few contrived tool-calling traces. Instead of one tool call per step, the model writes a TypeScript program against a generated API over the tools, the program executes in a sandboxed runtime, and the model curates what comes back — only what it prints or returns — instead of every intermediate result. -Tool presentation belongs to the registry that owns tool visibility: implementing a second presentation as an after-the-fact waterfall transform would make correctness depend on listener order and fight [reconstructable requests](../../implemented/architecture/2026-07-05-reconstructable-requests.md).

It is represented by a normal `ToolDefinition` for dispatch but stays outside the filterable capability layers, so restrictions cannot accidentally remove Code Mode's only entry point. Calls traverse the complete tool pipeline — `tools/pre-execute` → monotonic guards → `tools/execute` around dispatch → `tools/post-execute` → immutable `tools/result` notification — exactly like native calls; a permission plugin can inspect the program text before it runs, and final-result observers see the normalized outer outcome.

The runtime receives the run-scoped signal, not only the caller's outer signal, so any way the outer run settles also aborts work inside the runtime. 3. **Settle after quiescence.** When the runtime settles, the bridge aborts outstanding work and drains the dispatch queue before returning. Success returns captured output and presentation metadata. A runtime failure becomes `CodeRunFailedError`; backend rejection uses the registry's normal error boundary. Both produce structured error results, and no sub-call can append after `run_code` settles. -**Sub-call `additionalContext` is omitted.** Injecting it during `run_code` would break parent call/result adjacency, while one program can produce many contexts.

The registry carries that array even when the program later throws, and the loop appends each entry only after the outer result and every sibling result in the step. An outer post-execute block discards tool-deferred entries and exposes only contexts explicitly attached by the blocking decision. **Concurrency is serialized.** Each run owns a dispatch queue, so even `Promise.all` executes tool calls in submission order. Settlement abandons queued calls that have not started. Parallelism requires per-tool concurrency-safety metadata. -**Presentation.** `run_code`'s render intent is decided here per the [render-intent RFC](../../implemented/architecture/2026-07-02-tool-render-intent-union.md): `presentCall` → a `generic` card, `kind: 'execute'`, title = the program text, `rawInput` = the same program text; `presentResult` → a `generic` card whose content is the captured output (from `meta`).

As the event log accumulates turns, the derived message history eventually approaches the model's context window — the model then truncates mid-response (`max-tokens`) or degrades. **Compaction** is the mitigation: replace a run of older history with a concise summary, keeping recent context intact. + +The [session surface](../architecture/2026-06-18-session-surface.md) was built as the foundation for exactly this — an ordered projection over the event log with a `surfaceOp: { op: 'replace', start, end }` operation purpose-built to shadow a range of entries and insert a replacement, with `sourceEventSeqs` recording provenance so the decision replays deterministically. What remained was the plugin that *decides what to compact and produces the summary*. + +Two forces shape the design. First, compaction policy and reusable token measurement vary independently: measurement belongs to the LLM-family [`ctx.tokenMeter` service](../architecture/2026-07-15-replay-token-meter-service.md), while summarization can be a model call, a template, or a remote service. Second, `SurfaceEventType` is closed to five event types (`user/message`, `assistant/message`, `tool/result`, `context/message`, `steering/message`); only those may carry `surfaceOp`. A bespoke `compaction/*` event therefore **cannot** itself appear on the surface — the compiler rejects `surfaceOp` on it and the invariants plugin rejects it at runtime. + +## Decision + +### Compaction is a capability seam, split interface / implementation + +Per the [capability-seams Agent Note](../architecture/2026-06-13-capability-seams.md), compaction ships as separate packages so the contract, the algorithm, and (later) the consumer surface evolve independently: + +1. **Interface** — `@deepseek-ai/dsh-compact`: an abstract `CompactService` owning the `ctx.compact` key, the `CompactionResult` vocabulary, and the `compact/*` session events. It declares `compactIfNeeded()` and `compactRegion()` as **abstract** — the contract states *what* compaction does, not *how*. +2. **Implementation** — `@deepseek-ai/dsh-compact-basic`: a concrete `BasicCompactService` that consumes `ctx.tokenMeter` and owns the tail→head retention walk, summarization via `ctx.llm.stream()`, the surface replacement, the lock, post-step pressure, and canonical context-overflow recovery. `summarize()` is its sole subclass hook; pricing and replay stay with the meter. +3. **Consumer** — deferred. A `/compact` tool and slash command will `inject: ['compact']` and call the contract; they are intentionally out of scope here so the seam settles first. + +### The contract depends on `dsh-session` and `dsh-llm` — a deliberate deviation + +The capability-seams Agent Note states the interface package "depends only on cordis" (true of `dsh-bash`, whose vocabulary is self-contained). Compaction **cannot** honor that: its verbs act on an agent-owned `Session` (`compactRegion(start, end, agent)`) and its output uses the content vocabulary (`CompactionResult.summary: ContentBlock[]`). There is no way to express the contract without naming `Session`/`SessionEvent` (from `dsh-session`) and `ContentBlock` (from `dsh-llm`). + +This is not a coupling smell — it is the contract's domain. The "only cordis" guidance was always shorthand for "the interface depends only on what the contract genuinely names, and never on an implementation." `dsh-session` and `dsh-llm` are themselves interface/vocabulary packages, not implementations; `dsh-compact` still imports no backend. The seam's real invariant — *consumers and implementations evolve independently behind an abstract service* — holds intact. + +### Abstract `compactIfNeeded` / `compactRegion`, algorithm in the backend + +An earlier draft put the full algorithm (the retention walk, token-summing, text extraction) as concrete methods on the interface. That recouples the contract to one strategy: a backend that wants a different retention policy or event sequence would have to fight inherited concrete code. Making both core methods abstract puts every *how* decision in the backend and keeps the interface a statement of *what*. Token measurement is not a compaction hook at all; the singleton service lets multiple consumers share one per-session replay fold. + +`compactIfNeeded(agent, trigger, signal)` takes an explicit `'pressure' | 'context-overflow'` trigger and cancellation. It reads only the latest durable routed request; no header means no work, while any routed provider/model target uses the singleton estimator. `compactRegion(start, end, agent, signal?)` uses `agent.session` as its single session identity and keeps an optional signal for manual callers. The default summarizer resolves its target from explicit config, the latest logged routed target, then agent options, and records the provider/model pair after any `llm/stream` routing. + +### Automatic pressure runs after successful durable step work + +Successful-call pressure cannot run at pre-step because final `agent/request` routing, provider output, tool results, buffered context, and steering do not exist there. Serial `agent/post-step(agent, turn, step, signal)` fires after those facts are durable and before `step/end`. `dsh-compact-basic` measures the canonical logged request through `ctx.tokenMeter`, so the next request sees any replacement without a speculative envelope override. + +Canonical provider context overflow takes a separate path. The failed step closes, `agent/request-error` receives the original request error and consecutive retry count, and compact-basic forces one useful balanced reduction. It returns retry only if `session.surface.replaceGeneration` increases; the loop then opens a new numbered step and reconstructs its request from the durable log. No range, no replacement, recovery failure, cancellation, an exhausted cap, or an unrelated error preserves the original provider failure. The complete lifecycle decision is in the [after-call recovery Agent Note](../architecture/2026-07-10-after-call-compaction-pressure-and-overflow-recovery.md). + +``` +assistant/message → tool/result/context/steering +await serial agent/post-step ⟵ pressure compaction inside the successful step +step/end + +provider overflow → step/end +await waterfall agent/request-error ⟵ forced compaction between attempts +retry → next numbered step/start ⟵ derives from the replacement surface +``` + +### Retention is turn-agnostic; tool-pairing balance is the only structural guard + +Auto-compaction checks after **every successful** step, not once per turn. This is load-bearing for runaway-turn survival: a tool-heavy ReAct turn appends an `assistant/message` + a `tool/result` per step, so the surface grows within a turn. The post-step check can compact early closed tool pairs before continuation opens the next step, and provider-confirmed overflow remains the backstop when a request crosses the limit first. + +`compactIfNeeded` retains the smallest tail of whole surface units whose estimated size reaches `retainTokens` and compacts older nodes. A unit is a complete closed step or one no-step message. If the token cutoff lands inside a step, retention expands until the cut is tool-pairing balanced. Balance is checked on surface order, not log sequence, because replacement summaries have new sequence numbers at old surface positions. `dsh-compact` exports the before/after edge helpers; their per-session cache folds only appended surface-tail nodes while `replaceGeneration` is unchanged, does no event reads for log-only growth, and rebuilds current membership and balances after replacement. `compactRegion` rejects boundaries that split a tool call from its result. The in-flight turn receives no special retention. + +A runaway turn thus compacts exactly like any other history: its early *closed* steps get summarized while its recent steps stay verbatim. When the only compactable content left is an un-splittable open tail step (its tool-calls have no results yet), compaction declines (`null`) and retries once that step closes. + +**Single-unit overflow is out of scope, by design.** If a single retained unit — one closed step, or a large free entry such as a pasted `user/message` — *alone* exceeds the budget, compaction cannot help and the next model call may go out over-budget. Bounding an individual unit's size is a separate concern (output truncation), handled elsewhere; compaction makes no promise about it, and the harness without such a mechanism can still break on a single oversized unit. This is named honestly rather than papered over. + +### Head-anchoring: one auto checkpoint, always at the head + +Auto-compaction always starts at the surface head, merging the prior checkpoint with newly compacted history so only one automatic checkpoint remains. `shadowedRange` is therefore positional rather than a numeric sequence interval: a newer summary sequence may occupy an older surface position. `shadowedSeqs` records the authoritative surface order. Manual mid-range compaction may leave multiple checkpoints. + +### Approximate convergence invariant + +`resolveConfig` supplies usable defaults: threshold ratio `0.8`, retained tail `floor(contextWindow × 0.16)`, empty summarization provider/model overrides, `maxTokens: 8192`, `compactionRetries: 1`, `maxOverflowRetries: 1`, and `auto: true`. Optional top-level `thresholdRatio` and `retainTokens` override the policy for the token meter's single context window; retention must remain below the resulting threshold. Convergence remains dynamic because provider output caps can be spent on hidden or surfaced reasoning tokens and summary size is unpredictable. If pressure remains over threshold, `compactIfNeeded()` re-compacts the head checkpoint up to the configured retry count, but each committed summary must be smaller than what it shadows. Overflow bypasses threshold and retained-tail policy for one maximal balanced head reduction, leaving the newest indivisible unit. + +### Surface replacement: `compact/*` events are log-only; one `user/message` carries the summary + +Because `SurfaceEventType` is closed, the summary cannot ride on a `compact/*` event. The backend instead appends a **single `user/message`** with `surfaceOp: { op: 'replace', start, end }` whose `content` is the (framed) summary and whose `sourceEventSeqs` covers the shadowed entries *and* the bookkeeping events. The `compact/*` events are pure log records (lock + provenance). The surface mutation sits **inside** the lock — `compact/end` is the last event appended: + +``` +compact/start → log-only. Acquires the lock. +[summarize older range via the backend] +compact/summary → log-only. Provenance: raw summary, range, shadowed seqs, token count. +user/message → surfaceOp { op:'replace', start, end }. THE surface mutation (framed summary). + deriveMessages() renders it as a user-role message. +compact/end → log-only. Releases the lock (carries `error` on a recoverable failure). +``` + +`deriveMessages()` then yields `[summary_as_user_message, ...retained_entries]`. Reusing `user/message` is honest rather than a workaround: a summary genuinely *is* user-role context. + +### Checkpoint framing + incremental merge (backend-private) + +The basic backend wraps the summary as established checkpoint context and tags it for incremental merging on the next cycle. The raw summary remains on `compact/summary`. Framing is backend policy; the seam promises only that one replacement user message carries the possibly framed summary. + +### Blocking via a log-recorded lock, plus a crash/recoverable failure taxonomy + +The `compact/start … compact/end` bracket is justified, in order of what now does the work: + +1. **Crash-detectable orphan + provenance** (primary). Summarization is a slow model call persisted *after* `compact/start`. A crash mid-summarization leaves a `compact/start` with no matching `compact/end` — a detectable orphan. Releasing the lock last (rather than first) converts the crash window from *silent corruption* into that detectable orphan. +2. **Prevents concurrent compaction.** `compactRegion` refuses to start if the current turn holds an unmatched `compact/start`. (The loop is single-threaded across either awaited automatic seam, so this is also a re-entry tripwire — a thrown "already in progress" signals a real bug.) + +Two failure paths, both documented: + +- **Crash** (the loop dies mid-summarization): a dangling `compact/start`, no closer. Because `compact/*` are **log-only**, the orphan is **inert** — the surface replacement never landed, so the full, uncompacted history derives correctly. Generic turn-repair (`interruptedTurnClosers`) closes the turn with a synthetic `turn/end`; the orphan sits *before* that `turn/end`, so the turn-scoped in-progress check never sees it and a crash cannot wedge future compaction. +- **Recoverable** (summarization throws but the loop survives): the backend appends `compact/end` with its **`error`** field set and leaves the surface untouched. Post-step pressure warns and continues; overflow recovery delegates so the original provider error remains authoritative. + +`compact/end` keeps its `error?` field (mirroring `tool/result`'s self-contained error — one event tells success from failure without correlating a sibling). There is no separate `compact/error` event. + +**Core session repair stays compaction-agnostic — deliberately.** `interruptedTurnClosers` is never taught about `compact/*`. Teaching it would force every future `xxx/start … xxx/end` plugin pair to patch a core module — exactly the coupling the capability-seam architecture exists to avoid. Because the log-only orphan is inert, no special repair is needed: generic turn-repair plus the inertness of an un-landed surface mutation is sufficient. + +## Alternatives considered + +- **The full algorithm as concrete interface methods** — rejected because it recouples the contract to one retention strategy. Both core methods are abstract; reusable measurement is a separate LLM-family service and `summarize()` is basic's sole hook. +- **Compaction on `agent/request` or provisional `agent/pre-step` inputs** — rejected because neither proves the final durable request and both couple generic lifecycle to compaction-specific envelope data. Post-step replay plus canonical overflow recovery covers both successful and rejected calls. +- **A separate `compact/error` event** — rejected: `compact/end` keeps an `error?` field, mirroring `tool/result`'s self-contained error — one event tells success from failure without correlating a sibling. +- **Teaching core turn-repair about `compact/*`** — rejected: the log-only orphan is inert, and a core module patched for every future `xxx/start … xxx/end` plugin pair is exactly the coupling the capability-seam architecture exists to avoid. + +## Consequences + +- **Packages**: `packages/compact/compact` supplies the interface and `compact-basic` supplies the backend. `packages/llm/token-meter` owns replay-aware measurement independently. The consumer tier is deferred. +- **Automatic seams**: `agent/post-step` (`@mode serial`) handles successful-call pressure and `agent/request-error` (`@mode waterfall`) handles final request failures after the failed step closes. Generic `agent/pre-step` remains a four-argument checkpoint with no compaction-only prompt/prefix payload. +- **`SessionEventMap`** gains `compact/start` / `compact/summary` / `compact/end` by declaration merging (merge-extensible); `SurfaceEventType` is **not** touched. These are session events, not cordis `Events`, so the event-taxonomy gate needs no entry. +- **`dsh-compact`** owns `toolPairingBalancedBefore(session, seq)` and `toolPairingBalancedAfter(session, seq)`, the cached surface-edge checks that `compactRegion` and `compactIfNeeded` use to avoid splitting a tool-call/result pair. The cache validates current membership by seq and answers both edges from one per-cut balance sequence; stale or missing seqs and orphan results reject. `dsh-session` continues to own the surface `replace` operation, ordered event sequences, and rewrite generation. +- **`dsh-invariants`** drops its `surface replace: start must be <= end` assertion: a head-anchored compaction lands a high-seq replacement entry at an older range's *position*, so `start > end` numerically is normal and valid (the range is positional, validated by the surface's `indexOf` checks that remain). The turn-enclosure invariant is reused unchanged. +- **Wiring**: `examples/repl-agent/cordis.yml` loads zero-config `dsh-token-meter` before `dsh-compact-basic`; the service-wide window and compact defaults make the pair usable without repeated numeric policy. + +## Testing + +- **Unit:** Real Loader and invariant plugins cover whole-unit retention, convergence failure, both `compact/end` outcomes, head anchoring, open-tail refusal, inert crash orphans, forced below-threshold overflow, generation proof, caps, and original-error preservation. +- **Loop:** Tests pin post-step after durable tool results and before `step/end`, actual `agent/request` routing, closed failed steps, fresh retry numbering, and complete thrown/in-band overflow → compaction → reconstructed retry composition. +- **With-key e2e:** A real model and bash session with lowered limits triggers compaction, records a complete `compact/start…end` pair, shrinks the surface, and finishes the task. +- **Snapshot gap:** Runaway-turn compaction cannot yet replay because the summarization call records no `assistant/chunk` events or `sessionId`; interleaved summarization-call replay remains follow-up work. diff --git a/docs/rfc/implemented/feature/2026-06-21-subagent-capability-seam.md b/.agents/notes/implemented/feature/2026-06-21-subagent-capability-seam.md similarity index 68% rename from docs/rfc/implemented/feature/2026-06-21-subagent-capability-seam.md rename to .agents/notes/implemented/feature/2026-06-21-subagent-capability-seam.md index e2871532c8..3ed2090b22 100644 --- a/docs/rfc/implemented/feature/2026-06-21-subagent-capability-seam.md +++ b/.agents/notes/implemented/feature/2026-06-21-subagent-capability-seam.md @@ -1,16 +1,16 @@ -# RFC: Subagent capability seam +# Agent Note: Subagent capability seam Status: implemented -> The full seam is shipped: the `dsh-subagent` interface, the `dsh-subagent-mock` test backend, and the `dsh-tool-subagent` consumer; the two in-process backends (`dsh-subagent-spawn`, `dsh-subagent-fork`); the nested-agent snapshot infrastructure ([per-session snapshot replay](../testing/2026-06-22-subagent-snapshot-replay.md)); and the out-of-process `dsh-subagent-acp` backend ([its RFC](2026-06-22-acp-subagent-backend.md)). +> The full seam is shipped: the `dsh-subagent` interface and `dsh-tool-subagent` consumer; the two in-process backends (`dsh-subagent-spawn`, `dsh-subagent-fork`); the nested-agent snapshot infrastructure ([per-session snapshot replay](../testing/2026-06-22-subagent-snapshot-replay.md)); and the out-of-process `dsh-subagent-acp` backend ([its Agent Note](2026-06-22-acp-subagent-backend.md)). ## Problem -The harness has a long-deferred seam for **subagents** — an agent delegating work to another agent.

The stdio and ACP products need the same behavior, isolated by session cwd: a global system-prompt section leaks one workspace's files into another live ACP session. + +Neighboring products establish useful conventions but differ in details. Codex treats `AGENTS.md` as native, Claude Code uses `CLAUDE.md` and familiar system-reminder-style user context, and opencode supports both names with one winner per directory plus lazy nested discovery. The harness needs cross-tool compatibility without loading duplicate or contradictory files from the same scope. + +The lifecycle has two distinct classes of content. The initial applicable chain is stable enough to live in the request prefix and benefit from provider prefix caching. Nested files, edits, candidate switches, and removals happen after the session starts and belong in durable append-only history rather than the frozen prefix. + +## Decision + +The implementation lives in `packages/context/workspace-context` as `@deepseek-ai/dsh-workspace-context`. It is a request-context extension, not a core service or a filesystem backend. `@deepseek-ai/dsh-agent-core` mounts it for both product front doors and forwards its config. The plugin consumes `agent/session-prefix`, `tools/post-execute`, and the optional `ctx.fs` capability. + +The plugin does not statically inject `fs`. Providerless product trees therefore boot normally and the plugin no-ops until a filesystem provider exists. All production reads go through that provider. Candidate probes call `lstat` before `resolve`, so a repository-owned final-component symlink is rejected rather than followed outside the workspace. The session-prefix signal and dynamic tool execution signal propagate through resolution, metadata probes, and streaming reads, so cancellation does not wait for an unrelated filesystem scan. Once `lstat` identifies a regular-file winner, a provider exception or disagreement during resolve/stat is classified as unavailable: it is neither interpreted as a deletion nor allowed to fall through to a lower-priority candidate. + +### File Names And Precedence + +The default per-directory candidate list is `['AGENTS.md', 'CLAUDE.md']`. The list is configurable as `instructionFileCandidates`, and `AGENTS.md` is an ordinary first candidate rather than a hidden priority. In one directory, only the first existing regular-file candidate loads. With defaults, `AGENTS.md` is native and `CLAUDE.md` is a compatibility fallback. + +Candidate entries are same-directory file names. Empty entries, `.`/`..`, and entries containing `/` or `\` are ignored. Lowercase names, local variants, and other same-directory names can be opted into explicitly; rule directories and import semantics are outside this contract. + +The user-global file is fixed at `$DSH_HOME/AGENTS.md` and is not affected by `instructionFileCandidates`. `$DSH_HOME` defaults to `~/.dsh`, matching the harness-level home role of `~/.codex` or `~/.claude` rather than introducing a plugin-specific home. Tilde expansion and the default live in `dsh-paths` so future harness features share the same convention. + +### Baseline Prefix + +On the first request of an agent-loop instance, the plugin contributes one user-role message through `agent/session-prefix`. It loads the user-global file first, then finds the project root by walking upward from `agent.session.header.cwd` to a configured root marker (default `.git`), then loads one candidate from each directory from the root to the cwd. A `.git` file and a `.git` directory are both valid markers, covering linked worktrees and submodules. Without a marker, the cwd itself is the root. + +The plugin prepends its contribution before `await next()` returns, so session-prefix contributions appear in plugin registration order. In the product spine workspace instructions are registered before a skills catalog and therefore appear first. The loop deep-freezes the composed prefix, logs it in `EpochHeader.messagePrefix`, and reuses it verbatim for that instance. It is request state, not `Session.deriveMessages()` history. + +A resumed agent creates a new loop instance and recomposes the baseline from current files, with the new prefix anchored by the resume request header. This permits current baseline content on resume without mutating a prefix already used by an earlier instance. + +The baseline is a user-role `<system-reminder>` with `Instructions from: <path>` sections and explicit authority and precedence language. This familiar model-facing frame avoids a harness-specific XML vocabulary. Project paths are root-relative and the user-global path is `~/.dsh/AGENTS.md` for the default home or `$DSH_HOME/AGENTS.md` for a configured home. A literal `</system-reminder>` inside file content is escaped. The package README owns the exact current [prompt shape](../../../../packages/context/workspace-context/README.md#prompt-shape). + +### Dynamic Discovery And Refresh + +After a successful first-party `read`, `write`, or `edit` call, the `tools/post-execute` listener reconciles the touched descendant chain and every scope already known to the session. A newly reached scope is returned through `additionalContexts` for the next request using an `Additional instructions from: <path>` system-reminder. Under Code Mode, `run_code` defers sub-dispatch contexts onto its outer result, so the same update is appended only after the parent result rather than being injected mid-call. + +A content edit appends `Updated instructions from: <path>`, states that the new content replaces the previous content, and includes the complete current file. If precedence changes from one candidate to another, the message also names the previous path and says it no longer applies. If no candidate remains, the plugin appends `Instructions removed: <path>` and states that the previously loaded instructions no longer apply. + +Dynamic messages use a raw `context/message` envelope because the plugin owns the complete system-reminder framing. Core context injection therefore supports `envelope: 'raw'`; callers that omit it retain the canonical `<context source="...">` wrapper. `context/message.meta` carries opaque JSON state that is persisted but never rendered to the model. + +Shell commands are not discovery triggers. Local bash calls start fresh shells, and inferring reached paths from arbitrary command strings would require shell semantics the prompt plugin does not own. + +### Duplicate Suppression And Change Detection + +Every dynamic workspace context event stores versioned metadata with `{ action, scope, path, previousPath?, digest? }`, where `digest` is SHA-1 over the loaded content. The model-facing prompt has no HTML comments, hidden markers, or headings that are parsed back into state. + +At reconciliation time the plugin scans plugin-owned `context/message` events and derives the latest state for each visible scope. A short per-session pending map begins only after the immutable top-level `tools/result` proves an `additionalContexts` entry survived every post-execute listener, then covers the interval before the loop appends that context to the log. Each entry records the open `{ turn, step }`: an equal durable `context/message` at or after its sequence boundary confirms and removes it, while a matching `step/end` arriving first means the loop discarded its context buffer, so the plugin removes both the pending entry and its version-cache fast path. A nested Code Mode result stages its changes under the parent's opaque execution token so repeated sub-dispatches in one run do not duplicate them; the parent result rolls that provisional state back and commits only contexts retained by outer policy. + +An unchanged path and digest is suppressed. A logged removal is a tombstone, so a reappearing candidate becomes a new `set`. Resume works from persisted metadata. If compaction removes an instruction event from the visible surface, that state no longer suppresses a later load, matching the fact that the model can no longer see it. Only changes actually included under the byte budget enter metadata or pending state, so an omitted file remains eligible on a later touch. + +The frozen baseline keeps an in-memory path/digest map for comparison. A later successful filesystem touch appends baseline edits or removals as dynamic messages; it never rewrites the prefix. During resumed prefix composition the plugin also reconciles visible dynamic scopes, so nested changes made while the agent was offline can append an update before the first resumed request. + +There is intentionally no watcher. Detection occurs at the next successful structured filesystem touch or resumed prefix composition. A provider failure produces no removal; absence is only accepted when all configured candidates in that scope were probed successfully. + +### Byte Budget And Bounded Reads + +`maxBytes` is required and applies separately to a rendered baseline or one dynamic reconciliation batch; there is no implicit or unbounded render budget. Non-positive and non-finite values disable loading. When content exceeds the budget, broader files are omitted before the most-specific file is truncated. A visible `Workspace instruction budget ...` notice names omitted and truncated paths and byte counts, and output never exceeds the configured bytes. + +`maxSourceBytes` is a positive per-file cap with a 1 MiB default. The loader checks reported size before reading and still consumes content through `streamText()` with a running UTF-8 byte count, so missing/stale metadata cannot force an unbounded allocation. An oversized winning candidate is unavailable rather than a reason to fall through to another same-directory name. The plugin deliberately keeps no process-wide cache and never retains instruction prose. It keeps only `{ path, version, digest }` per effective scope in a `WeakMap<Session, Map<scope, state>>`: a matching provider `FsVersion` plus matching effective prompt state skips the read, while a changed version triggers a bounded read and SHA-1 confirmation. SHA-1 remains the cross-provider content identity persisted in visible structured metadata; provider versions are only an in-memory invalidation fast path. Cache transitions for model-visible changes commit only when the corresponding context survives the complete tool-result policy chain, and are invalidated if that accepted context is later dropped with its aborted step before reaching the log. + +## Alternatives considered + +**Use a global `ctx.systemPrompt.section()`.** Rejected because one Cordis context can host sessions with different cwd values, while repository-owned text is lower-authority context rather than top-authority provider system content. + +**Inject the baseline on every `agent/pre-step`.** Rejected because repeated history injection wastes tokens, complicates duplicate state, and prevents a structurally stable provider prefix. Prefix composition gives a frozen, logged, per-instance baseline while dynamic append-only messages handle changes. + +**Load both `AGENTS.md` and `CLAUDE.md` in one directory.** Rejected because repositories in transition commonly duplicate guidance across both files. Ordered candidates make precedence explicit and configurable. + +**Parse rendered headings or hidden comments to recover loaded state.** Rejected because instruction prose can contain the same text, causing silent false positives. Persisted JSON metadata provides an unambiguous state channel that is invisible to the model. + +**Summarize files with a model.** Rejected because instruction files are already curated summaries; another model call is nondeterministic and can erase edge-case requirements. Deterministic full text with byte budgeting is simpler. + +## Consequences + +Workspace guidance is isolated per session and shared by both product front doors and every tool presentation mode. Initial instructions benefit from stable prefix caching, while nested and changed content remains durable and replayable. The generic session/agent context contract includes optional raw framing and JSON metadata, both propagated through prompt-submit and post-tool `additionalContexts` arrays without flattening entries. + +Repository text remains untrusted input. Lower-authority user-role framing, explicit precedence language, delimiter escaping, and symlink rejection reduce risk but do not eliminate prompt injection. Permission and sandbox layers treat workspace files as data rather than authority. + +The system is event-driven rather than watch-driven. Edits are not visible at the exact filesystem mutation instant unless that mutation goes through a structured tool; externally changed files are noticed on the next successful structured touch or resume. This keeps the design deterministic and provider-neutral. + +## Deferred + +Bash-derived path reporting, recursive startup scans, file watchers, lowercase defaults, `.claude/CLAUDE.md`, `.claude/rules/*.md`, import directives, ACP `additionalDirectories`, trust acknowledgements, and model-generated summaries are deferred.

Every turn fails identically until the config is fixed; the process itself stays up (matching the repo rule that explicit config references must not be silently ignored — the enforcement point is the assembly because no earlier universal moment exists). - A tool provider that returns the reserved rest-entry name has the same prompt-assembly failure shape as an unknown listed name.

The dev invariant ([dsh-invariants](../../../../packages/support/invariants/src/index.ts)) recomputes `messagePrefix + boundary derivation` against every loop-built request; an unlogged prefix cannot reach the wire. +- **Frozen per instance.** Reuse is structural, not disciplined: the cached product cannot change mid-session, so the provider's prompt cache holds by construction and the prefix extends the cacheable region at zero marginal cost per step. A process restart or `ctx.agents.resume()` is a new instance: it recomposes, and any drift lands attributably on the `'resume'` header snapshot. This is the routing rule the seam creates: session-frozen openers ride the prefix; content that changes mid-session rides the append-only history channels (`agent.inject()` or tool/prompt-submit `additionalContexts` — [the interception-seams Agent Note](2026-06-30-interception-seams.md)), each a durable `context/message` paid once and prefix-cached thereafter. +- **Exact in the durable request envelope.** Composition precedes the instance's first `agent/pre-step` and request boundary. The first routed request logs the current prefix on its header, so post-step token pressure reads the exact prefix together with the actual prompt, tools, and routed model; no compaction-only parameter is carried through the generic pre-step seam. A composition interrupted by cancel/dispose is discarded, never cached: an abort-aware listener's degraded fallback cannot leak into later requests, and the next turn recomposes under a live signal. + +Because composition runs before the boundary snapshot, a composing listener's session append joins the CURRENT request's derived history.

Local workspace discovery is naturally a process-backed `rg` workflow; remote or virtual filesystem backends may expose their own search API, may not share a local `ripgrep` view, or may not support discovery at all. The v1 should not require every filesystem backend to implement search before the file read/write/edit seam has proven that need. + +Search output also has two distinct budgets. The tool needs enough raw `rg` output to compute a stable logical result, but the model should receive only a bounded preview plus a recovery path when the formatted result is larger than the inline budget. The generic spill policy only sees the final tool result, so it cannot recover matches that a search tool already omitted. Search therefore needs tool-owned retention and best-effort formatted-result spill. + +## Decision + +`glob` and `grep` are conditional model-facing tools in `@deepseek-ai/dsh-tool-fs-search`, backed by the bash seam, not by new `ctx.fs` provider methods. At plugin load, the package checks `command -v rg >/dev/null 2>&1` through `ctx.bash.resolve(request)` followed by `ctx.bash.run(spec)`; if the command exits nonzero, the package logs a warning and registers neither tools nor prompt sections. A probe that cannot start, times out, aborts, is killed, or produces no exit code fails plugin load loudly because that is a broken bash executor rather than an absent optional binary. When registered, execution uses the same `ctx.bash.resolve(request)` followed by `ctx.bash.run(spec)` flow with fixed `rg` command templates assembled by the tool. The tool layer owns schemas, argument validation, shell quoting, result parsing, result formatting, retention, formatted-result spill handoff, and timeout declaration. The bash executor owns request defaulting/capping, subprocess execution, process-group termination, environment scrubbing, raw output capture, and backend substitution across local, sandboxed, or remote bash implementations. + +The tools do not use `ctx.bash.start()` and do not create model-visible background tasks. They run as ordinary foreground tools from the agent loop's perspective: the tool call returns only after the `rg` command exits, times out, is aborted, or fails. `defineTool({ timeoutMs })` declares the cooperative tool-call budget, `@deepseek-ai/dsh-timeout-policy` enforces it through `exec.signal`, and the tool forwards that signal into the bash request before `resolve()` / `run()`. The bash backend's own timeout remains a second safety cap; whichever aborts first wins. + +The tools align `path` with Claude Code's search tools while binding resolution to the bash workdir, not to `ctx.fs`. The tool derives the bash request workdir from `exec.agent?.session.header.cwd`, mirroring `dsh-tool-bash` and `dsh-tool-fs`; when no session cwd exists, it omits `request.workdir` so the bash implementation applies its configured cwd or process cwd through `resolve()`. For `grep`, `path` is an optional ripgrep target and may be a file or directory; omitted means the resolved bash workdir. For `glob`, `path` is an optional directory search root; omitted means the resolved bash workdir. Relative `path` values resolve against that workdir. Returned paths are displayed relative to the resolved bash workdir when possible and are intended to be follow-up-readable only in co-located deployments where the bash workdir and filesystem `read` root are the same workspace. v1 documents that deployment requirement but does not perform runtime cross-service validation. Remote or virtual filesystem search is deferred until there is a shared workspace/root contract or a provider-specific search backend. + +The package does not inject `fs`. It injects `tools`, `systemPrompt`, and `bash`; it deliberately reads `spillStore` with `ctx.get('spillStore')` instead of static inject because formatted-result spill is optional. Existing `@deepseek-ai/dsh-tool-fs` deployments that only want `read` / `write` / `edit` do not need to load bash. Deployments that load search need `rg` available in the bash executor environment for the tools to enter the model-visible schema. + +### Package shape + +The v1 package stays small. Inside `@deepseek-ai/dsh-tool-fs-search`, the source layout is: + +```text +src/index.ts +src/glob.ts +src/grep.ts +src/search-core.ts +src/shell-quote.ts +``` + +`glob.ts` and `grep.ts` own their parameter validation, command construction, result parsing, formatting, and registration. `shell-quote.ts` is one shared helper because shell quoting is the safety boundary both tools must use; `search-core.ts` is the other (an implementation-time amendment to the original four-file plan): the `SEARCH_*` error vocabulary, the bash-run + raw-output acquisition, the formatted-spill handoff, and workdir-relative display are byte-identical between the two tools, and duplicating that delicate plumbing per tool is exactly the missed extraction the symmetry convention flags. Command builders must not hand-roll quoting or concatenate unquoted model-controlled values into the shell command. + +### Schemas and config + +`glob` exposes the small discovery shape: + +```ts +interface GlobArgs { + pattern: string + path?: string +} +``` + +`grep` exposes the OpenCode-style minimal shape: + +```ts +interface GrepArgs { + pattern: string + path?: string + include?: string +} +``` + +Routine budgets stay out of the model-facing schema. `@deepseek-ai/dsh-tool-fs-search` owns these defaulted, validated config fields: + +| Field | Default | Role | +|---|---:|---| +| `globMaxResults` | `100` | Max paths retained inline; matches Claude Code's default `GlobTool` result limit. | +| `grepMaxMatches` | `250` | Max flat matches retained inline; matches Claude Code's default `GrepTool` `head_limit`. | +| `grepMaxLineBytes` | `2000` | Max bytes retained for one matched-line preview, applied with `TextRetainer({ kind: 'head', maxBytes: grepMaxLineBytes })`. | +| `rawOutputMaxBytes` | `20000000` | Max complete raw `rg` stdout the tool will parse; matches Claude Code's ripgrep raw buffer. | +| `timeoutMs` | `30000` | Tool-call timeout attached to both tool definitions and enforced by `@deepseek-ai/dsh-timeout-policy`. | + +`globMaxResults` and `grepMaxMatches` use `ItemRetainer({ kind: 'head' })`. `grepMaxLineBytes` uses `TextRetainer({ kind: 'head', maxBytes: grepMaxLineBytes })` for each matched line so preview cuts preserve UTF-8 boundaries. This follows the [tool result retention library](../architecture/2026-07-06-tool-result-retention-library.md) mapping for discovery items: collect the complete result, retain head items inline, and keep path mapping, grouping, and per-line preview outside the retainer. `grep` does not expose `case_insensitive`, `head_limit`, `offset`, `count`, multiline, context lines, output modes, or file type filters in v1. A model that needs surrounding context reads the matched file with `read`; a model that needs later results follows the returned spill locator's retrieval hint. + +The Claude Code values are reference points for the two-layer budget, not model-facing schema precedent. Its dedicated search tools buffer raw ripgrep output up to 20 MB for internal processing, use a 20-second ripgrep timeout on non-WSL platforms (60 seconds on WSL), then apply search-specific caps before the model sees a result: `GrepTool` defaults to `head_limit = 250` and persists formatted results above 20,000 characters, while `GlobTool` defaults to 100 paths and persists formatted results above 100,000 characters. This Agent Note mirrors the raw-buffer and inline-count defaults, chooses a 30-second default search timeout, and uses this harness's `ctx.spillStore.saveText()` path for formatted-result recovery. + +The `path` field follows the same split as Claude Code: `grep.path` is a file-or-directory ripgrep target, while `glob.path` is a directory search root. v1 does not expose a separate cwd/workdir argument on these tools. + +`include` is one positive glob filter, not a list and not an exclude syntax. Reject comma-separated or negated include patterns up front with a structured argument error. Every model-controlled value used in a shell command, including `pattern`, `path`, and `include`, must pass through the package-private shell quoting helper. + +### Execution + +`glob` builds a fixed `rg --files` command rooted at the resolved directory search root (`path` when supplied, else the bash workdir): `rg --files --glob <pattern> --sort=modified --no-ignore --hidden`, plus VCS metadata excludes for `.git`, `.svn`, `.hg`, `.bzr`, `.jj`, and `.sl`. This aligns with Claude Code on hidden/ignored-file discovery and modified-time ordering while keeping VCS internals out of broad searches. The tool parses one path per line, maps results back to paths relative to the bash workdir when possible, pushes each path into `ItemRetainer({ kind: 'head', maxItems: globMaxResults })`, and formats the full sorted path list for a spill artifact when the retained result is capped. + +`grep` builds a fixed line-oriented `rg --json` command against the supplied file/directory target (`path` when supplied, else the bash workdir) so file path, line number, and line text are parsed without colon-splitting ambiguity. It consumes `match` records, treats malformed JSON or malformed match records as `SEARCH_FAILED`, maps result paths relative to the bash workdir when possible, applies per-line preview retention with `grepMaxLineBytes`, pushes each match into `ItemRetainer({ kind: 'head', maxItems: grepMaxMatches })`, then groups only the retained preview matches by file for inline output. The spill artifact stores the full formatted match list, not only the omitted tail, so the retrieval hint points at the same logical result the model saw. + +Raw `rg` stdout is an internal transport detail. The tool requests `stdoutMaxBytes: rawOutputMaxBytes` through `ctx.bash.resolve()` and parses `stdout.text` only when the executor returns untruncated stdout within that cap. If stdout is larger than `rawOutputMaxBytes`, or the executor still returns `stdout.truncated`, the tool fails with a clear search error telling the model to narrow `pattern`, `path`, or `include`. The tool never exposes raw `rg` output or bash raw spill paths to the model. + +Only stdout is a parse source. Stderr is diagnostic text for invalid patterns, runtime `rg` disappearance after registration, and search failures; if bash truncates stderr, the tool uses the retained stderr tail with a truncation note and does not read `stderr.spillPath`. + +If `ctx.bash.run()` reports `aborted` because the tool timeout or caller cancellation fired, the tool returns a structured failure rather than pretending there were no matches. If bash reports its own timeout first, the tool likewise fails with a clear timeout message. Nonzero ripgrep exit semantics are tool-owned: exit 0 is success with matches, exit 1 is success with no matches, invalid pattern / runtime `rg` disappearance / inaccessible search workdir are failures. + +Search failures use a package-owned `HarnessError` subclass with `SEARCH_*` codes, not `FsErrorCode`, because these tools are not `ctx.fs` provider operations. The v1 vocabulary is `SEARCH_INVALID_PATTERN`, `SEARCH_FAILED`, `SEARCH_RAW_OUTPUT_OVERFLOW`, and `SEARCH_ABORTED`. Model argument validation failures such as missing required fields, blank strings, or unsupported negated/list `include` values remain ordinary tool argument errors. + +### Formatted result spill + +`ctx.spillStore` is optional and used only for model-facing formatted results. This is the first tool-owned spill call pattern in the codebase, and it is intentional because search retention is item-level policy: `globMaxResults` caps paths and `grepMaxMatches` caps matches while the tool still holds the complete logical result. The generic `dsh-spill-policy` caps final text bytes on `tools/post-execute`; by then a search tool would already have omitted later paths or matches, so the policy cannot recover them. + +When a search produces more logical results than the inline cap and `ctx.spillStore` is present, the tool saves the complete formatted result with `saveText()`. The spill owner is the calling agent's session header id (`exec.agent?.session.header.id`); without that owner, the search keeps the inline result and reports that the complete result could not be saved. The spill source is the tool execution identity: `{ toolName: exec.name, callId: exec.callId, label: 'result' }`. The suggested filenames are `grep-results.txt` and `glob-results.txt`; the spill backend still treats them as hints, never paths. + +When spill storage is absent, the call has no session owner, or saving fails, the tool still returns the inline page and a footer explaining that the complete result could not be saved. Search success must not turn into an `isError` result solely because formatted-result spill storage is unavailable. + +The bash raw output stream and the formatted search spill artifact are different artifacts. Raw `rg` stdout is parsed only in memory within the requested bash stdout cap; the formatted spill artifact is the stable model-facing recovery locator produced by `ctx.spillStore.saveText()`. + +### Result shape + +A capped `glob` result with successful formatted spill returns the inline page and a spill notice: + +```text +<first N paths> + +(Showing N of M paths. Full sorted result stored at: /.../session-abc123/9f8e7d-glob-results.txt. Use read with offset/limit, or grep this path to search within it.) +``` + +A capped `grep` result with successful formatted spill returns grouped preview matches and a spill notice: + +```text +Found N of M matches + +<file> +Line 12: ... + +(Full grep result stored at: /.../session-abc123/9f8e7d-grep-results.txt. Use read with offset/limit, or grep this path to search within it.) +``` + +If the complete logical result fits under the inline cap, no formatted spill artifact is created. If the complete logical result is too large but formatted spill is unavailable, the footer says that the result was capped and the complete result could not be saved. The `truncated` / omitted count is a budget fact, not an incomplete-search fact; timeout, invalid regex, runtime `rg` disappearance, inaccessible workdirs, raw-output overflow, binary skips, and parse failures stay in tool-domain error or incomplete fields. + +## Alternatives considered + +**Put `glob` / `grep` on `ctx.fs`.** Rejected for v1: it forces every filesystem backend to grow a search API and makes local ripgrep behavior part of the provider seam.

It remains a reasonable optimization if bash-backed search proves too shell-string-sensitive or if foreground streaming becomes necessary. + +**Use `ctx.bash.start()` for streaming early stop.** Rejected: `start()` creates model-visible background task semantics: task ids, owner tokens, `bash_output`, `bash_kill`, completion notifications, and no built-in timeout. `grep` needs a foreground tool result, not a background bash workflow. If streaming search becomes necessary, the right abstraction is a foreground streaming process handle on the bash/process seam, not borrowing the public background-task API. + +**Expose bash raw spill paths to the model.** Rejected: a bash raw spill path contains raw `rg` stdout (`rg --json` records for grep), not the stable formatted search result. Search parses raw stdout only as an internal transport; model recovery uses a formatted result saved through `ctx.spillStore.saveText()`. + +**Add `spillStore.saveFile()` for bash output normalization first.** Rejected for this Agent Note's v1: `saveFile()` would help a future bash normalization pass move existing executor spill files into session-scoped spill storage, but search only needs bounded in-memory raw `rg` stdout before producing the model-facing artifact. `saveText()` is sufficient for the formatted search result. + +**Rely on the generic `dsh-spill-policy`.** Rejected: generic post-execute spill sees only the final tool result. If `grep` / `glob` return the first page inline, the generic policy cannot recover omitted results.

It self-skips where `rg` is not on the test process PATH (a CI accommodation mirroring the keyless e2e skip); the fake-executor suite carries registration and execution coverage for missing `rg`, plus the per-file 100% coverage gate. +- Snapshot gap note for the transcript-visible spill notice: this landed with the gap note, not a snapshot. The snapshot tier replays the acp-agent tree, and adding the search plugin there changes the assembled system prompt — every expected output would need re-recording with a real key, which the implementing environment did not hold. The spill notice's exact transcript text is pinned by unit tests (`formatGlobOutput`/`formatGrepOutput` and the through-the-registry spill tests); wiring the plugin into the acp-agent tree plus a `test:snapshot:record` pass is the follow-up for the next key-holding session. + +## Consequences + +- `glob` and `grep` are conditional model-facing tools in `@deepseek-ai/dsh-tool-fs-search`, not `ctx.fs` provider methods and not part of the existing `@deepseek-ai/dsh-tool-fs` root plugin.

Registration is a Cordis effect and is removed with the contributing plugin fiber. `list()` exposes declarations without running resolvers, keeping the environment surface enumerable for diagnostics and future prompt/UI consumers. + +The registry rebuilds a trusted overlay for every foreground and background bash `ToolExecution`: + +- `DSH_HOME` is always the absolute configured Harness home. The standalone [`@deepseek-ai/dsh-home`](../../../../packages/util/home/README.md) utility owns its precedence: explicit `dshHome`, then ambient `$DSH_HOME`, then `~/.dsh`. +- `DSH_SHELL=1` is always present and identifies a model bash child managed by DeepSeek Harness. +- `DSH_SESSION_ID` is present when the execution has an agent and equals `agent.session.header.id`. +- The built-in persistence translator contributes `DSH_SESSION_JSONL` only when `ctx.sessionPersistence.locate(header)` returns `kind: 'jsonl'`. + +Session persistence remains the fact owner: JSONL does not depend on tool-bash or register shell variables itself, and hooks continue to consume `locate()` directly. Tool-bash is the translation layer from the persistence fact into a shell convention. Other plugins that need shell-visible facts depend on the registry and register their own keys; they do not modify `process.env`. + +The bash seam exports `DSH_ENV_PREFIX` as the single namespace source and derives `DshEnvironmentKey` from its `typeof`. Tool-bash derives built-in names and model guidance from that constant, while executors use it for filtering and channel validation. The seam carries the managed overlay separately as `BashExecRequest.dshEnv` / `BashExecSpec.dshEnv`. Ordinary `env` remains the general in-process plugin surface used by hooks, but cannot contain managed keys; symmetrically, `dshEnv` cannot contain ordinary keys. The local executor rejects either wrong channel before spawn, removes every inherited ambient managed key, applies its ordinary scrub/terminal environment/explicit `env`, and finally merges the trusted `dshEnv` snapshot. This guarantees that a missing value means absent now rather than inherited from an outer or previous harness. The model-facing tool still ignores model-supplied `env`/`stdin` arguments. + +The bash tool description teaches only the durable convention: current harness environment facts are available through managed `$DSH_*` variables and may be inspected when needed. It does not enumerate persistence-specific keys or add a permanent system-prompt section. Tool schemas are already logged in request headers and tool output is logged as `tool/result`, so no new session event is required. + +The [Claude Code and Codex hook bridges](2026-06-30-hook-bridges.md) resolve transcript location from the same persistence seam when constructing payloads. Codex uses `transcript_path: string | null`; Claude Code preserves its string field and falls back to `''`. Hook lookup neither materializes nor flushes a session. + +## Peer product findings + +Peer products separate stable identity from physical storage. Codex injects stable `CODEX_THREAD_ID` into spawned shells while recorder and hook surfaces own transcript paths. Claude Code supplies `session_id` and `transcript_path` as structured hook/status input. OpenCode carries identity in structured tool context; Kimi Code expands a session placeholder; Reasonix keeps the active session path on its controller. The portable rule is to inject identity at the invocation boundary, let storage resolve location, and never use a process-global current-session variable in a concurrent harness. + +## Lifecycle and persistence semantics + +A fresh session receives its id before the first turn, so its first bash call can read `DSH_SESSION_ID` and a JSONL target. The JSONL file may still be absent until the first successful turn-end checkpoint, and during an open turn it contains only the last flushed prefix. `DSH_SESSION_JSONL` is a location hint, not an authorization credential or freshness guarantee. + +Resume reuses the loaded header and therefore the same id and location. Fork and spawn create new session ids and locations. Parent and child calls resolve from their own `ToolExecution.agent`; each command receives an immutable snapshot even when calls overlap. A persistence service replacement affects later collections because the translator queries `ctx.get('sessionPersistence')` at execution time; the registry itself is effect-scoped and HMR-safe. + +`dshHome` is session-independent deployment context. Agent-core resolves one value through `@deepseek-ai/dsh-home` and routes it to both tool-bash and local skill discovery; standalone consumers call the same resolver. If top-level `dshHome` and `skills.local.dshHome` are both supplied and resolve differently, composition fails instead of exposing contradictory homes. Persistence may change independently without freezing its facts into the session prefix. + +## Testing + +Unit coverage pins registry declaration validation, effect disposal, per-execution collection, the `dshHome` precedence, and the local executor's `DSH_*` scrub/rebuild order. Request-recording tests cover foreground/background snapshots, no-agent calls, absent/JSONL persistence, ignored model `env`, and parent/child isolation. JSONL/SQLite locator contract tests and both hook bridge suites pin available and unavailable transcript dialects. + +A keyless full-loop integration drives the real agent loop, JSONL persistence, tool-bash, and bash-local on the first turn. The child prints `DSH_HOME`, `DSH_SHELL`, session id, JSONL target, and an inherited stale sentinel; the test verifies current values, absence of the stale variable, pre-flush file absence, and the eventual persisted header. Snapshot coverage pins the generic bash description in the recorded request header. No with-key test is required because the contract is deterministic local execution rather than model choice. + +## Alternatives considered + +**Only an id plus `find`.** Search cannot know a custom root or backend layout and races under multiple sessions. + +**Only an absolute path.** A path can be unavailable, lazy, or representation-specific and is not stable session identity. + +**Global `process.env`.** Concurrent agents would overwrite one another and nested harnesses would inherit stale current-session values. + +**Put persistence instructions in the session prefix.** A session prefix is frozen while the active service can change across HMR or future backend switching; persistence-specific guidance would become stale. + +**A typed waterfall event.** Listeners cannot declare ownership without running, and later listeners can silently overwrite keys. A registry detects key conflicts at registration and remains enumerable. + +**Have each persistence backend register bash env directly.** That reverses the dependency from storage into one consumer and forces bash into deployments that do not use it. `locate()` is also still required by hooks. + +**A model-facing `session_info` tool.** It adds schema and another call while bash already supplies the query surface; the registry generalizes to future environment facts without one tool per fact. + +## Consequences + +Every model bash child receives current Harness home and shell identity, and agent calls additionally receive stable session identity. JSONL-backed calls get an optional target path; non-file persistence omits it honestly. The complete `DSH_*` namespace inside these children is managed by the harness: ambient values are removed, current trusted values are re-added, and ordinary callers cannot use `env` to bypass ownership checks. + +The namespace is discoverable but not secret. Paths can reveal configured roots, lazy targets can be absent or stale, and a command can override variables inside its own shell syntax. Consumers treat them as correlation and environment facts, verify transcript metadata when attribution matters, and rely on sandbox/filesystem policy rather than variable secrecy for authorization. diff --git a/.agents/notes/implemented/feature/2026-07-10-parallel-tool-call-execution.md b/.agents/notes/implemented/feature/2026-07-10-parallel-tool-call-execution.md new file mode 100644 index 0000000000..4904da5bd5 --- /dev/null +++ b/.agents/notes/implemented/feature/2026-07-10-parallel-tool-call-execution.md @@ -0,0 +1,101 @@ +# Agent Note: Parallel tool-call execution by per-call safety + +Status: implemented + +## Problem + +An assistant message may contain several sibling `tool-call` blocks.

Consecutive parallel calls form one group; every exclusive call forms a singleton group and an ordering barrier. Groups execute sequentially. Classification is lazy: the scheduler resolves the next call after each barrier and reclassifies every later call before replenishing a parallel pool. If a registry mutation makes that call exclusive, the current pool drains before the call starts as the next barrier. + +For example: + +```text +[parallel read(A), parallel read(B), exclusive write(A), parallel read(C)] + +→ [read(A), read(B)] +→ [write(A)] +→ [read(C)] +``` + +`read(A)` and `read(B)` may overlap. `write(A)` starts after both finish, and `read(C)` starts after the write finishes. + +Every group uses a rolling pool bounded by `maxParallelToolCalls`: the loop starts calls in model order up to the cap and starts another whenever one settles. An exclusive group is a pool of one. A cap of `1` preserves serial execution. + +Only dispatch and the tool body overlap. `tools/pre-execute` and `tools/post-execute` run in model order because middleware may maintain ordering-sensitive state. `tools/execute` wrappers run around concurrent dispatches and therefore must be reentrant across distinct executions. + +Each started call appends `tool/call` immediately before its pre-execute gate. Completed dispatches occupy model-order slots, and a commit cursor appends `tool/result` and collects `additionalContexts` only when the next slot is ready.

An abort during a group stops replenishment, waits for already-started calls, commits their results in order, drains accepted batch context after those results, and then ends the step through the existing abort path.

It must not directly mutate the parent session or other parent-owned state; it returns its outputs to the loop, which commits them in model order. + +Any shared state touched during execution must be concurrency-safe. This includes tool wrappers and providers: they may serialize internally or enforce their own capacity, but they must support concurrent dispatch without corrupting state. + +## Configuration and declarations + +`maxParallelToolCalls` is a positive AgentLoop deployment cap shared by every agent the factory creates.

Web search, web fetch, and filesystem read opt in.

A positive value scans the raw session events for the most recent `context/message` with this plugin's source and injects when none exists, wall time moved backward, or the event is at least the configured age.

If interval suppression leaves no earlier same-turn reading, the duration is `unavailable`. Duration formatting uses compact whole-second units and clamps backward wall-clock movement to zero. The explicit turn and step make every retained reading attributable to its historical preparation attempt after later turns append more context. + +### Durability and request reconstruction + +Each reading remains a normal surface node until compaction shadows it; positive interval scheduling never removes existing readings. A later request therefore sees the cumulative unshadowed readings that affected earlier preparation and steps, rather than a system-prompt value rewritten in place. + +The plugin contributes nothing to system-prompt assembly. `request/header` contains no time-context text; request reconstruction obtains the complete durable surface prefix at each `step/start`.

The primary log supplies user-authored `user/message` prompts and the recorded `assistant/chunk` sequence. `dsh-llm-replay` derives one model-call script per session, binds child logs to fresh child sessions, and is the only mocked boundary. The agent loop, bash and filesystem implementations, Code Mode worker, subagent provider, workflow worker, Cordis tools, presenters, and TUI are production implementations. + +The suite rejects a journey when its tool-call sequence differs, an expected event count is missing, a tool result is an error, a turn ends in error, a workflow lifecycle is incomplete, or the live child-session count differs from the fixture set. These assertions prevent an attractive terminal expected output from hiding a failed or bypassed production path. + +The live-model fixtures use `DSH_SNAPSHOT=record`; record mode rewrites their primary and child JSONL logs and terminal expected outputs. The deterministic Cordis toolchain keeps an authored complete JSONL script because reliably coercing a live model through five exact tool boundaries and two children is not a stable recording contract. `DSH_SNAPSHOT=refresh` replays every committed script keylessly and rewrites only derived terminal expected outputs.

Open requires only readable root `package.json` and `cordis.yml` files; every other file is an optional resource. Both paths return the same read-only aggregate and distinguish their source through explicit origin state. + +`project.edit()` clones project documents into a working copy. Domain commands such as install, configure, enable, disable, and addPlugin modify only the working copy. Each command immediately re-inspects its owning feature, and the final commit checks all relationships and files again. + +```text +validate feature requirements and resource ownership + -> validate every affected document + -> compute changed and removed paths + -> compare existing files with the session's original text + -> write through one commit boundary + -> return a new SdkProject snapshot and ChangeSet +``` + +Validation failure or an external edit causes zero writes. “One commit” means only zero pre-write side effects and one write entrypoint. `ChangeSet` describes final feature, plugin, and file changes for Review & Apply and create completion. + +## Features and resource ownership + +A feature is a first-class behavior object. Shallow base classes implement install, configure, enable, disable, required/requires validation, and common state inspection. Features with fixed, exclusive, or additive feature options share these lifecycles. Only features whose resource contributions depend on project context or require custom round-tripping use dedicated behavior classes; other features declare their actual differences through standardized data. + +Each feature contributes stable-keyed Cordis config entries, npm dependencies, environment placeholders, and owned files. The registry rejects two features that declare the same resource key during initialization. Different feature options within one feature may share resources, which that feature resolves from the final option set. + +A Cordis config entry anchors feature installation. The npm package name assigns the entry to a feature, and the entry ID distinguishes several instances of one plugin package. An npm dependency without a feature-owned Cordis config entry leaves the feature uninstalled. Once a Cordis config entry exists, a missing npm dependency, unreadable Cordis plugin config, or resource conflict puts the feature into an inconsistent state; the config command shows diagnostics and refuses speculative modification. + +Configuring the same feature option updates only its owned config keys and preserves unknown keys. Replacing a feature option removes old resources that are exclusive and still confirmable. If an old resource cannot be confirmed or an owned file was modified by the developer, the whole operation fails. + +## Questions and workflows + +TypeScript `Question<T>` objects keep defaults, validation, applicability, and types together. `PromptPort` is the only interface between the domain layer and the terminal library, and helper provides one thin `ClackPromptPort`. Create and config inject their own command-line input and output streams and retain ownership of cancellation, return, and completion semantics in their workflows. + +Create keeps its stateful question order in one wizard, while config keeps final-state selection in one workflow. Both use the same feature configurator for feature options and dedicated inputs, so adding an ordinary feature, feature option, or parameter does not require changes to both entrypoints. + +## Project documents and templates + +Only structured files that helper reads or modifies have concrete document objects: `package.json`, `cordis.yml`, `.env`, `.env.example`, the root `tsconfig.json`, and the pnpm workspace file. Document objects own parsing, cloning, validation, and serialization. Concrete classes and modules use `*File` and `*-file.ts` names respectively. Business code does not manipulate YAML/JSON ASTs directly, and malformed shapes fail loudly at the owning document boundary. + +README, entrypoint code, build configuration, `.gitignore`, and other one-shot text artifacts use one complete template per real file. Complete product copy such as CLI usage, creation and recovery messages, installation and retry guidance, and the default persona also comes from package-local templates owned by the package that presents it. + +Helper provides the generic typed `TextTemplate` renderer, and caller packages load their own templates through package-local asset URLs. + +Templates use Handlebars strict mode and `noEscape` without custom processing. File owners encode typed values for the target language. Template source escapes interpolation as `\{{model}}` when it must emit the downstream literal unchanged. + +## Command and runtime boundary + +Scripts supports `dsh-sdk start/dev/build/config`. Start dynamically loads a module target and calls its named entrypoint. Dev adds TypeScript and local-workspace source resolution before following the same path. Build invokes the project's installed tsdown. Config opens one edit session and commits after Review & Apply. Generated projects run `tsc -b` directly for typechecking. + +HMR is an explicit Cordis config entry loaded by dev and start. Its required `node-addon-require-builtin` package is supplied transitively by the scripts package and is absent from the generated project's `package.json`. + +Dev and start execute the developer entrypoint, where developer code handles command-line arguments and cwd. Developers pass `--model=<name>` and `--resume=<session-id>` to start the standard flow. + +## Repository live-link mode + +Create-sdk retains a hidden `--link-workspace` option for Harness repository development and e2e. The parser accepts it, but help, public flag lists, and ordinary user documentation omit it. It accepts no repository-path parameter; the repository root is derived upward from the executing create-sdk module. + +Link mode preserves the ordinary project file shape. `@deepseek-ai/*` points into `packages/`, Cordis-related npm dependencies point into `vendor/`, and shared lower-level packages resolve to the same physical copy used by the repository so Cordis type merging cannot produce multiple module type definitions. npm uses `file:`, pnpm uses `link:` with automatic peer installation disabled, and Yarn uses `portal:` plus resolutions. Repository packages must be built first. + +## Future work + +- **Replaceable required spine roles.** The current `spine` owns the full implementation set, including SystemPrompt and LLMService, through one fixed feature option. Developers cannot replace or switch these roles and must edit Cordis config entries manually. +- **Service contracts and package declarations.** When replacing a builtin service, a Cordis plugin currently cannot declare the services it provides through `provides` metadata, so the SDK cannot assist configuration during development or check compatibility at runtime. A corresponding protocol remains to be designed. +- **Feature parameter descriptions.** Feature-specific inputs currently require handwritten declarations. The SDK cannot derive interactive parameters automatically from arbitrary Cordis plugin config or npm package.json information. Future declarative metadata may expose a limited parameter set without turning arbitrary Cordis plugin config into a generic form. +- **SDK application-level configuration.** The current project resource model describes Cordis config entries and config keys owned by individual Cordis plugins, so every SDK-managed setting must belong to one plugin. Cross-plugin or whole-application settings have no independent persistence location. Future work must define an application-level configuration document and its ownership, read, and mutation boundaries. + +## Alternatives considered + +**Keep the static Catalog and central engine.** This minimizes the initial rewrite, but feature parameters, round-tripping, owned files, and create/config reuse continue to accumulate in one coordinator. Splitting files shortens the file without consolidating responsibility. + +**Use `wizard.json` and a generic Questionnaire.** Static forms cannot directly express feature requirements, option switches, existing-value refill, and project-resource changes. Types, gates, and dynamic options still connect through string registries and a procedural `run()`, creating another internal DSL. + +**Expose the live-link flag.** The mode depends on Harness monorepo layout and unpublished packages and serves repository development only. Making it public would create a project-creation contract that the SDK cannot support outside the repository. + +## Acceptance criteria + +- Create and config modify projects only through `SdkProject` and `ProjectEditSession`; any business, document, or concurrency validation failure before writing leaves the filesystem unchanged +- Adding an ordinary feature, feature option, or parameter extends only its typed spec or owning behavior object, without adding a central switch to create or config workflows +- Helper owns the feature model, npm dependency and other resource configuration, and inconsistent-state detection +- Structured files change through `*File` document objects; one-shot files and complete product copy come from package-owned Handlebars templates, and business decisions do not enter a template DSL +- `dsh-sdk start/dev/build/config` is the runtime product surface, typecheck uses `tsc -b` directly, HMR is not injected by command mode, and only the scripts package transitively supplies `node-addon-require-builtin` +- `--link-workspace` exists only as a hidden repository-development option and preserves one module identity under npm, pnpm, and Yarn + +## Risks + +- Behavior objects and typed specs create two extension shapes. Dedicated classes must remain limited to features that truly depend on project context or custom behavior, or the design will grow a meaningless type hierarchy +- Optimistic concurrency checks and pre-write validation cannot recover from an I/O failure during writing; callers must still report a possible partial commit to the developer +- Hidden link mode depends on repository layout and package-manager link semantics and must change with either one +- The Cordis loader resolves `node-addon-require-builtin` from its own module path, so the scripts package must continue to satisfy that optional peer under npm, pnpm, and Yarn npm dependency layouts +- Handlebars `noEscape` makes typed model construction responsible for target-language encoding; new template fields must be escaped

The summary the model sees carries no reference to what it shadows — the `shadowedRange` provenance lives only on the log-only `compact/summary` event — and no tool lets the model read a shadowed span back. Whatever the summarizer drops is gone from the model's reachable world, even though the append-only log holds every byte. Repeated compaction compounds this: the head checkpoint is rewritten every pass, so the request prefix takes a full prompt-cache miss each time, and earlier summaries are re-summarized generation after generation. + +The root cause is one artifact playing two conflicting roles. An **index** wants to be frozen, chronological, and cheap; the model's **working memory** wants a global view, re-prioritization, and mutability. A single summary can be neither well. + +No mainstream coding harness gives the model in-loop recall, and none of the surveyed implementations makes compaction prefix-cache-aware. An event-sourced session — originals durable, seq-addressable, replay-exact — is the natural substrate for both. + +## Proposal + +Split the checkpoint into two classes and make shadowed history reachable. + +### Frozen index checkpoints + +Newly stale history splits into chunks by deterministic policy: accumulate toward `chunkTokens`, snap edges with `toolPairingBalancedBefore` / `toolPairingBalancedAfter`, prefer turn boundaries, and place the final boundary as close to the retain boundary as balance allows, so the trailing slice shrinks to roughly one turn. Each chunk is compacted by one `compactRegion` call into an **index stub** (`stubTokens`, ~100–200 tokens): + +- two or three lines of what happened; +- a keyword line of low-frequency literal anchors — exact error strings, values, config keys — grouped by kind; +- a code-composed footer: `[checkpoint c<summarySeq>: shadows conversation span #<start>–#<end>; originals retrievable via history_read]`. Pointers are assembled from provenance, never model-authored. + +A committed stub is never rewritten and never re-enters a later compaction region. A stub call's input is layered: the fixed preamble and the byte-identical pass-start state checkpoint (the shared prefix across all calls in the phase), then the keyword lines of all previously committed stubs — so a new entry indexes what is distinctive to its chunk instead of repeating the directory — the one or two most recent committed stubs for chronological continuity, and the slice itself. Sibling stubs from the same pass are not inputs (the concurrent phase forbids it; turn-aligned boundaries carry local continuity instead), and the state checkpoint is background only, never material to summarize into the stub. A slice consisting of recalled content is stubbed by code alone — a pointer line, no LLM call. A failed stub call degrades the same way: its slice gets a code-only pointer stub and the pass continues, making the state rewrite the only hard LLM dependency in a pass. + +### The state checkpoint + +One mutable working-memory document (at most one; zero before the first pass), positioned after all stubs and before the retained tail. Each pass rewrites it from the previous state plus this pass's staled content — O(previous + new), under the merge-don't-restate rule already in the summarization prompt — covering decisions, current state, constraints, and next steps. It carries its own footer and a size cap at the scale of today's summary. + +An inflation guard bounds the whole pass: if the post-compaction size is not strictly below the pre-compaction size, nothing commits and the turn proceeds; the attempt defers until more stale history accumulates. The guard compares one metric on both sides — provider-reported usage from the request path, falling back to the character estimator on both sides. + +### Pass execution + +- Chunk slices are surface position ranges. A pass runs two phases: all summarize calls execute concurrently, buffered off-surface; then regions commit strictly left to right — chunks first, trailing slice last — so the state checkpoint lands after every stub through contiguous single-node replaces. Wall-clock stays near one summarize call. +- The superseded state checkpoint folds into the next pass's first chunk as ordinary history: no tombstone, no new primitive. Its stub omits it, `history_read` renders it labeled `[prior state checkpoint]`, and its footer travels with the rendered text, keeping every trailing slice reachable through the two-hop chain. +- Range selection is frozen-aware: the compactable span begins after the last committed index checkpoint, at the surface head only when none exists. A legacy session's existing head checkpoint is adopted as state-class — its text the merge base, its node folded like any superseded state. +- A crash in the summarize phase commits nothing; a crash mid-commit leaves a left-to-right prefix committed, and the resumed pass reads its merge base from the log's latest state-class `compact/summary` event and commits the remaining regions unconditionally — restoring `[stubs…][state][tail]` outranks shrinking. + +### The recall tools + +A new package `@deepseek-ai/dsh-tool-recall` (consumer-only, over the `dsh-session` and `dsh-compact` vocabularies) registers two model-facing tools: + +- `history_read(checkpoint, offset?)` — renders the shadowed span of any checkpoint in the log, including superseded ones, as `User:`/`Assistant:`/`Tool result:` transcript, paginated by a configured budget with a continuation cursor. +- `history_search(query, checkpoint?, limit?)` — case-insensitive literal scan over every shadowed span; returns snippets with checkpoint ids and coverage metadata (`scanned`/`matched`/`truncated`). The zero-match hint notes the scan is literal and points at direct `history_read` of a plausible checkpoint. + +Both read `exec.agent.session.events` (the tool-todo access pattern; non-agent callers rejected), render only surface-type message events, and return ordinary `tool/result`s — recalled bytes land at the context tail, logged, so reconstructability holds with no special casing. There is no new storage and no sidecar index: the session log is the archive, `compact/summary` provenance is the index metadata, and the tools are a read path over both. The tool schemas and the package's one system-prompt section are static strings; checkpoint ids reach the model only through footers. The transcript renderer moves from `compact-basic` into `dsh-session`, shared by summarizer and tools. + +### Cache and cost + +The request prefix after a pass is `[system][stubs…][state][tail]`. Frozen stubs are byte-stable across passes, so the miss begins at the token replacing the previous state checkpoint and stays O(new chunks + state + tail) — against position zero today. Recall output lands at the tail, leaving the prefix untouched. Per-pass summarize input is roughly twice today's plus an m·S background term, bounded by a `chunkTokens` floor (a small multiple of the state cap) and a validated `stubTokens`/`chunkTokens` ratio ceiling; a shared-prefix input layout (preamble, then the byte-identical pass-start state, slice content in the tail) lets sibling calls earn cached-rate rereads. + +### Packaging + +The design ships as a new backend `dsh-compact-recallable` on the existing `ctx.compact` seam, enabled by default in the shipped example configs; `compact-basic` remains as the reference implementation and the seam's design twin, in the pattern of the paired LLM adapters. The seam JSDoc's "at most one auto-generated checkpoint, always at the head" clause is relaxed to name both backend behaviors. + +### Relation to in-flight work + +- **Tool-result pruning** (the in-flight pruning service): its replacement nodes carry `sourceEventSeqs`; the same registry fold lists pruned results as recallable. Follow-up scope; neither blocks the other. +- **Provider-usage token accounting** (the in-flight move of compaction pressure onto provider-reported usage): supplies the guard's accounting; the implementation stacks after it. +- **"Query sessions" backlog item**: the cross-session generalization; this Agent Note scopes to the live session with tool names and rendering chosen so that work extends rather than collides. +- **Training**: when to recall is a learned behavior. The deterministic footers and keyword anchors give training a stable target, and recall usage is fully visible in the session log for trajectory export; benchmark and RL design proceed with the post-training side. + +### Follow-ups + +Specified during review, deferred until observation calls for them: + +- Guard degradation ladder (code-only rollup of the oldest stub prefix, footers preserved, rolled-up ids remain recall targets; then one summary after the frozen boundary) — on observed guard livelock or stub-region pressure. +- Echo detection on stub outputs (sentence-scale n-grams, short literals exempt, retry then strip) — on observed division-of-labor leakage. +- Periodic state refresh from chunk originals — on observed drift in the handoff probe. +- `stateFallbackThreshold` (full-detail state prompt below a stub count) — on short-session regression. +- Lazy registration of the recall tools — on measured context tax in never-compacting sessions. +- Amortized stub drafting at pre-step: as soon as stale-but-uncompacted content accumulates past `chunkTokens`, draft that chunk's stub at the next pre-step (a log-only draft event, written while the chunk's surrounding context is still live) and let the compaction pass commit drafts instead of summarizing in bulk — the deterministic, replay-exact equivalent of background compaction (the Claude Code session-memory pattern; OpenClaw demonstrates the synchronous semantics are identical). Trigger: observed pass latency, or stub-quality gains from drafting near-live proving out. +- Split summarizer models; model-chosen chunk boundaries; cross-session recall; semantic search fallback — each behind its own evidence. +- Richer `history_search` query forms — regex, and structured queries over logged JSON tool results (sql/jq-style, or agent-authored queries against an indexed store) — on demand from observed search misses; literal matching ships first because the recall path stays a pure function of the log. + +## Alternatives considered + +- **Staged delivery** (ship recall tools alone over today's backend; gate the checkpoint split on observed recall usage) — rejected: untrained models under-use any new tool, so the gate would measure training absence rather than design value, while the training side needs the complete mechanism to build environments against; the pre-release window is when persisted-format changes are cheapest; and the cache economics are first-party knowledge, not a hypothesis awaiting telemetry. The implementation still lands as stacked PRs with the recall tools first — construction order, not a decision gate. +- **All-frozen full-size summaries, no state checkpoint** — rejected: unbounded permanent-prefix growth, self-accelerating toward thrashing, with nothing left to re-prioritize. +- **Pure stubs, no state checkpoint** — rejected: presumes the model knows what it is missing; fails on unknown unknowns. +- **LLM aging/consolidation of frozen chunks** — rejected as a routine mechanism: summary-of-summary loss and frozen-prefix churn; the code-only rollup is its surviving form, deferred. +- **Full prefix as chunk-summarizer input** — rejected: O(N²); the state document gives the same background at O(state). +- **One summarize call emitting all outputs** — rejected: the summarize path has no structured-output enforcement; parsing one free-text response apart is the fragile seam the fail-closed design avoids. +- **Model-chosen chunk boundaries** — deferred: parse-and-validate cost against unproven value; chunk policy sits behind config. +- **Model-authored pointers** — rejected: pointers must be exact; deterministic assembly is. +- **FTS/vector index sidecar** — rejected in-session: the live log is in memory and bounded, a literal scan under budget suffices; an index earns its keep at cross-session scope. +- **Semantic search fallback / secondary-model extraction in the recall path** — rejected: an LLM or embedding call there breaks keyless replay determinism; recall stays a pure function of the log. +- **Raw events instead of rendered transcript** — rejected: leaks log-only vocabulary and chunk noise; the model reads what a model once saw. +- **Doing nothing (resume/fork as recovery)** — rejected: it makes recovery a human act. + +## Acceptance criteria + +- Auto-compaction over a long session yields `[stubs…][state][tail]` after every completed pass; prior stubs stay byte-identical across passes; committed stubs never fall inside a later region; the superseded state checkpoint folds without a tombstone, renders labeled, and stays reachable and searchable through the two-hop chain. +- Every checkpoint's surface text ends with the deterministic footer; footers round-trip through replay byte-identically; the state checkpoint's provenance records its wider input range. +- Nothing commits before all summaries exist and the guard passes on like-for-like accounting; a guard failure commits nothing and does not fail the turn; a mid-commit kill resumed at the next pre-step completes the pass with the state region committed unconditionally, merge base read from the log; a legacy head checkpoint is adopted as state-class. +- `history_read` renders any logged checkpoint's span under budget with a working cursor; `history_search` covers every shadowed span with checkpoint-id snippets and coverage metadata, asserted in particular by finding content that exists only in a span shadowed by a superseded state checkpoint — the regression pin for trailing-slice reachability; both reject non-agent callers and never-existing ids or orphaned `compact/start` with typed errors; recalled content appears as ordinary `tool/result`s; request-reconstruction invariants pass over sessions with compaction plus recall; one keyless snapshot scenario covers compact-then-recall end to end; tool schemas and the prompt section are byte-identical across passes. +- On the long-horizon bench suite: task success does not regress against `compact-basic` at equal budgets; a handoff-fidelity probe (restate K known decisions and constraints after a pass) scores no worse; recall usage frequency and hit usefulness are reported per run via the dsh bench report pipeline, alongside the stub-directory attention measurement and cache-hit telemetry. +- Seam JSDoc, the compaction capability-seam Agent Note, `architecture.md`, and the generated tool, config, persistence, and module-graph catalogs update in the same change; all budgets live in config; new source directories hold per-file 100% coverage with HMR disposal tests. + +## Risks + +- **Recall is a learned behavior**: untrained models will under-use it, and the bench report exists to track the gap while training closes it. Until then the state checkpoint keeps the floor at today's summary quality. +- **Unknown unknowns remain**: a detail absent from summaries and keywords draws no recall. Recall converts "unreachable even when suspected" into "reachable when suspected". +- **The stub directory occupies attention**: dozens of stable index cards per request may dilute focus; the bench measurement in the acceptance criteria tracks it against `compact-basic`. +- **Cost**: per-pass summarize input is roughly twice today's; short sessions sit near today's cost and quality, and the design pays off with session length. +- **State drift and division-of-labor leakage** are observable through the handoff probe and stub review; their counters are specified follow-ups. +- **Two backends** are a maintenance surface; the seam contract and the shared recall consumer bound it, and the bench comparison decides the default over time. diff --git a/docs/rfc/proposed/feature/2026-07-07-claude-code-and-codex-subagent-backends.md b/.agents/notes/proposed/feature/2026-07-07-claude-code-and-codex-subagent-backends.md similarity index 60% rename from docs/rfc/proposed/feature/2026-07-07-claude-code-and-codex-subagent-backends.md rename to .agents/notes/proposed/feature/2026-07-07-claude-code-and-codex-subagent-backends.md index bf4e85e020..620f39c4a4 100644 --- a/docs/rfc/proposed/feature/2026-07-07-claude-code-and-codex-subagent-backends.md +++ b/.agents/notes/proposed/feature/2026-07-07-claude-code-and-codex-subagent-backends.md @@ -1,10 +1,10 @@ -# RFC: Claude Code and Codex subagent backends (out-of-process delegation to external coding agents) +# Agent Note: Claude Code and Codex subagent backends (out-of-process delegation to external coding agents) Status: proposed ## Problem -Add isolated subagent providers for Claude Code and Codex.

Its create and config workflows are interactive, external Cordis plugins require manual dependency and configuration edits, command-line telemetry has no owning boundary, and interactive branches lack a stable test strategy. + +These gaps are coupled. Create and config already share questions, feature configuration, and `ProjectEditSession`; adding separate automation paths would duplicate that domain logic. External-plugin installation must update both the package manager's files and `cordis.yml`. Telemetry must observe commands such as create and build that do not boot Cordis. Interactive testing must exercise Harness behavior without making terminal rendering a brittle product contract. + +## Proposal + +The SDK extends the existing prompt and project-editing boundaries instead of creating parallel workflows. A non-interactive prompt port and structured feature plan drive create and config, `dsh-sdk create <source>` delegates dependency resolution to the project package manager before mounting the resolved package through `ProjectEditSession`, launcher-side telemetry wraps `create-sdk` and every `dsh-sdk` command, and injected prompt streams provide the primary interactive-test seam. + +| Capability | Product entrypoint | Owning mechanism | Required outcome | +|---|---|---|---| +| Headless project creation | `create-sdk --config <file>` or `--config-json <json>` with optional `--json` | `HeadlessPromptPort`, structured project answers, and a complete feature plan | No terminal blocking; missing required input is explicit | +| External Cordis plugin installation | `dsh-sdk create <source>` | Native package-manager `add` plus `ProjectEditSession` | The dependency and `cordis.yml` entry identify the package manager's resolved package | +| Developer-cycle telemetry | `create-sdk` and every `dsh-sdk` command | Launcher-side consent, payload, redaction, anonymous identity, and delivery services | Reporting is best-effort and cannot change the command result | +| Interactive regression coverage | Create and config tests | Injected `PromptPort` input/output and filesystem assertions | Tests cover Harness decisions and generated files without snapshotting terminal repainting | + +## Shared headless workflow + +### Structured input and lifecycle events + +Headless create accepts a JSON object either inline through `--config-json` or from a file through `--config`. Scalar fields supply the ordinary create answers, while `features` supplies the complete selected feature set, feature options, secrets, and dedicated values. Defaults remain valid only where the owning question declares one; the headless path never invents an answer for a required prompt. + +With `--json`, stdout is an NDJSON event stream. `done` means creation and any requested setup completed, `action-required` names an unanswered required prompt, and `error` reports another failure. Human-readable progress and package-manager output go to stderr so every stdout line remains parseable as one event. A caller responds to `action-required` by adding the missing value and running the command again. + +Create and config consume the same feature-plan shape. Create exposes it through the command-line inputs above; config uses it at the shared workflow boundary so a later automation entrypoint does not need a second feature-selection model. + +### Prompt and project-editing boundaries + +`PromptPort` remains the only boundary between SDK questions and an interaction implementation. `ClackPromptPort` handles terminals. `HeadlessPromptPort` consumes defaults exposed by the question contract and otherwise fails with the unanswered prompt; prefilled values normally prevent the port from being called. + +Both paths use the same `Question` objects, `FeatureConfigurator`, `SdkProject`, and `ProjectEditSession`. The headless path therefore changes how answers arrive, not how features are interpreted or files are committed. + +### Agent skill + +The repository ships a thin `SKILL.md` that teaches an agent to construct the structured input, request NDJSON, fill an `action-required` value, and retry. The skill invokes the public CLI and does not import an internal SDK API or introduce another project specification. + +## External Cordis plugin installation + +`dsh-sdk create <source>` accepts a package-manager-native npm specifier such as `pkg@version` or a GitHub specifier such as `github:owner/repo#ref`. After confirmation, it asks the project's package manager to add the source, compares the direct dependency names before and after the operation, reopens the project, and mounts each newly resolved package in `cordis.yml` through `ProjectEditSession`. + +The package manager owns source parsing, version or commit resolution, integrity data, lockfile updates, and any build policy. The SDK does not download or unpack a second copy through giget or pacote. An external plugin remains a dependency under `node_modules`; local plugin scaffolding remains a separate project-creation concern. + +## Launcher telemetry + +### Consent and collection + +Telemetry wraps the `create-sdk` initializer and the `dsh-sdk` launcher command lifecycle because project initialization, plugin creation, and build do not reliably boot Cordis. One event records the command name, duration, success, a random per-user anonymous identifier, and redacted `cordis.yml` and `package.json` text when those project files are eligible. + +Reporting is enabled unless a present telemetry config entry is explicitly disabled. `DO_NOT_TRACK` and CI deny reporting regardless of project configuration. A missing `cordis.yml` does not itself deny the event, but `package.json` content is included only when `cordis.yml` establishes that the directory is an SDK project. + +### Safety and delivery + +The payload builder never reads `.env`. It redacts secret-shaped keys and values, known token forms, PEM blocks, URL credentials, and high-entropy opaque strings in the two eligible text files. Redaction is a safety backstop rather than a guarantee; SDK projects must keep credentials in `.env`. + +The reporter uses a fixed endpoint and resolves every send path without throwing. Command dispatch records success or failure in a `finally` path, starts reporting after the command outcome is known, and drains within a bounded interval. Consent parsing, payload construction, storage, or network failures are swallowed only at this telemetry boundary and never alter the command's exit code. + +## Interactive workflow testing + +Create and config tests inject a `PromptPort` and scripted input/output streams into the existing workflows. Parameterized scenarios cover feature selection, feature options, secrets, cancellation, review, and apply behavior, then assert the resulting `cordis.yml` and other project files. The stable product assertion is the generated project state, not clack's ANSI redraw sequence. + +One or two optional real-PTY smoke tests may cover the shipped binary and TTY guard that injection cannot reproduce. Native PTY tooling does not belong on the required path unless it is reliable across the repository's supported Node and host versions. + +## Deferred work + +- Extend the headless create specification to express local `plugin` or `tool` scaffolding instead of defaulting that interactive choice to none. +- Expose the telemetry opt-out in create and config while preserving the consent representation in which only a disabled telemetry entry is written. +- Define whether GitHub source dependencies must be prebuilt or may run package-manager-controlled preparation scripts, and surface the policy before installation. +- Replace the telemetry package's `.invalid` endpoint placeholder with the production endpoint before release. + +## Alternatives considered + +**Build a separate headless creation engine.** This would duplicate questions, feature requirements, configuration behavior, and project-editing rules. Reusing the prompt and edit-session boundaries keeps one implementation of project semantics. + +**Make a specification file the primary automation interface.** Agents can pass the same typed JSON object inline, while people and CI may still use a file. A file-only protocol adds persistence and cleanup without adding semantics. + +**Use `npx skills add` as the project creator.** The skills CLI installs Markdown skills; it does not create SDK projects or install npm packages. The agent skill therefore drives the SDK initializer instead of replacing it. + +**Fetch GitHub and npm sources through giget or pacote.** A second fetch layer would duplicate package-manager resolution, integrity, lockfile, and lifecycle policy. Native dependency specifiers keep those decisions in the selected package manager. + +**Implement telemetry as a Cordis runtime plugin.** Create and build do not necessarily boot Cordis, so a runtime plugin cannot observe the complete developer command cycle. The launcher is the boundary shared by those commands. + +**Derive the anonymous identifier from git metadata.** Repository remotes can identify a project or organization. A random per-user identifier supports aggregation without encoding repository identity. + +**Collect only aggregate counters.** Aggregate-only events reduce exposure but cannot answer which plugins, dependencies, and configuration shapes developers actually use. This proposal accepts collection of redacted project text and makes that exposure explicit. + +**Use real PTYs and transcript snapshots as the primary test strategy.** Native PTY dependencies and terminal repaint sequences add platform and rendering instability while mostly testing clack. Injected interaction plus generated-file assertions tests the SDK-owned behavior directly. + +## Acceptance criteria + +- Create runs without a TTY from a complete structured input, emits only NDJSON on stdout under `--json`, and reports missing required input as `action-required` without writing a partial project. +- Create and config resolve the same feature-plan contract through the shared question, feature-configuration, and project-editing code paths. +- `dsh-sdk create <source>` uses the selected project package manager, mounts the dependency name that operation actually added, and fails loudly when no new dependency can be identified. +- The initializer and every `dsh-sdk` command reach one best-effort telemetry completion path; an explicit disabled entry, `DO_NOT_TRACK`, or CI prevents delivery, and telemetry failures never change the command result. +- Telemetry never reads `.env`, withholds unrelated `package.json` content when no `cordis.yml` exists, redacts both eligible text payloads, and uses an identifier unrelated to git metadata. +- Interactive tests cover create and config decisions through injected interaction and assert committed project files; any real-PTY coverage remains a narrow smoke layer. +- The agent skill documents the public structured-input and event contracts without depending on private package exports. + +## Risks + +- Full redacted `cordis.yml` and `package.json` text still reveals plugin and dependency names, URLs, paths, and configuration values to the endpoint operator, and heuristic redaction can miss a secret. +- Default-on reporting may surprise developers when no telemetry entry exists; the CLI must make the opt-out discoverable before release. +- A package-manager add can change `package.json`, the lockfile, and installed files before `ProjectEditSession` mounts the plugin, so a later mount failure can leave dependency changes that require manual recovery. +- GitHub dependencies may execute preparation or lifecycle code according to package-manager policy; an unresolved build policy is a supply-chain and reproducibility risk. +- Injected prompt tests do not prove raw-mode, signal, or repaint behavior in a real terminal; the optional smoke layer must cover only those residual contracts. + +## References + +- [Vercel Eve](https://github.com/vercel/eve) and [Vercel Labs

A private tool, kept on the skill maintainer's machine rather than committed to this repository, runs against a clean full-history checkout at refreshed `origin/master`.

Merge-commit reachability is the sole eligibility check — a stacked PR whose direct base is a feature branch is admitted whenever the base has since reached master, because the code the reviewer commented on is now on master regardless of the intermediate stack. The tool also resolves the landing merge's target parent; a landing shape it cannot reconstruct is logged to `skipped-pulls.json` and skipped. A single PR that fails preflight, acquisition, or evidence collection is skipped rather than aborting the whole run. The search stage fails loud when the window would exceed GitHub's 1,000-result search cap so no merged PR is silently omitted. The acquisition stage reads complete paginated connections for inline review comments, review submissions, and PR commits. PR conversation comments are not acquired because current GitHub state cannot prove which surviving commit preceded them after a force-push, so the adoption contract would exclude them unconditionally. The workflow admits acquired feedback only when GitHub reports the actor `type` as `User`, and only when both creation and last-edit timestamps strictly predate the PR merge (an equal-timestamp edit is treated as post-merge); review submissions use GraphQL `lastEditedAt` because the REST representation omits edit time. + +### Adoption evidence + +Each feedback item carries a stable source ID and bounded change evidence. When the reviewer's `commit_id` still belongs to the PR (force-push fail-closed), the tool selects the latest PR commit whose committer timestamp strictly predates the feedback as the baseline — not the reviewer's clicked commit, which may be an older commit. It never compares that baseline directly with the landing merge: such a diff includes unrelated changes from an advancing target branch. Instead, it gives the adoption reviewers two PR-specific patch snapshots. Let `B` be the feedback baseline, `T` the landing merge's target parent, and `M` the landing merge. The feedback-time snapshot is the tree diff from `merge-base(B, T)` to `B`; the final snapshot is the tree diff from `T` to `M`. A target-only change therefore appears in neither PR patch, while a change added to the PR after feedback appears only in the final snapshot. Force-pushed reviews, feedback that predates every surviving PR commit, and landing shapes whose target parent cannot be reconstructed are deterministically classified `unclear` before any reviewer sees them. Merge status, a resolved thread, an author's “fixed” reply, or a same-file edit is context rather than adoption proof; the PR author's own comments never reach the adapter as they cannot be adoption of themselves. + +### Dual-reviewer classification and drafting + +Two independently configured reviewer adapters classify every eligible item by provenance (`human-authored`, `forwarded-automation`, or `unclear`) and adoption (`adopted`, `rejected`, or `unclear`). Only matching `human-authored` plus `adopted` verdicts proceed. The adopted set then receives a second independent classification against the current skill: candidate, already covered, implementation-specific, or not feedback. A singleton may qualify; recurrence is not required. Disagreement receives one bounded re-evaluation and remains visible in run artifacts if unresolved. A single batch whose adapter output fails schema or id validation is failed closed at the batch level — every feedback item in it is marked unclear and routed to `excluded` — rather than aborting the whole run; the offending raw output is preserved under the run's private artifacts for debugging. If either adapter returns no valid result for any nonempty batch in an operation, the run exits non-zero and emits a failure record instead of reporting “no candidate.” + +The primary adapter drafts from structured agreed guidance, never raw review text. It remains tool-free and read-only by adapter-author contract: it returns complete candidate file content, which the tool validates before writing the sole target. Both adapters then review the same complete skill diff; blocking findings return to a bounded revision loop, and both must approve the same revision. The tool rejects staged changes and edits outside the target skill both before running the documentation and lint gates and again before reporting success, so a gate or concurrent process that adds another path cannot slip through. It restores its own write on failure using best-effort compare-and-swap so a concurrent maintainer edit is not overwritten. On success it saves a candidate bundle containing the source `origin/master` commit, source skill blob ID, reviewed diff, complete candidate, source feedback IDs and URLs, landed evidence ranges, adapter verdicts, and gate results; it never commits, pushes, opens, or merges a PR. + +### Reviewer adapter protocol + +Each private executable receives a byte-bounded, versioned JSON request on stdin and returns byte-bounded, schema-conforming JSON on stdout. The tool refuses to run when the two reviewer commands resolve to byte-identical executables — a minimum-bar mechanical check; guaranteeing that primary and secondary are backed by independent providers or models is the deployment operator's responsibility. The `access` and `tools` fields are contract markers on the adapter author, not an OS sandbox: reviewer subprocesses spawn with a scrubbed environment, `cwd` set to a private run directory rather than the repository root, and feedback wrapped in a nonce-tagged `<untrusted-feedback nonce="…">` block that every prompt instructs the model to treat as data; the 128-bit nonce prevents an untrusted body from forging the closing tag. Every subprocess uses bounded, abort-aware process-tree cleanup. Adapter authors implement each operation as pure read-only inference — even the `edit` operation returns complete candidate content in JSON, which the tool validates and writes to the sole target. Every production `git`/`gh`/gate spawn also uses the scrubbed environment so a pre-push hook's routing variables cannot silently redirect the maintainer. Candidate writes and the failure rollback use best-effort compare-and-swap against the last written content; the rollback also unstages the target so an adapter- or gate-staged candidate cannot survive a failed run into a later commit. + +### Promotion contract + +The promote helper starts from a clean checkout at refreshed `origin/master` and refuses to apply a candidate when the current skill blob differs from the bundle's recorded source blob. The operator then reruns the maintenance analysis or manually rebases the diff and repeats the candidate review; the helper never replaces a newer `SKILL.md` with stale complete-file output. After applying a current candidate, it opens a draft PR whose body lists the source feedback URLs or IDs, the landed commit range used as adoption evidence, the originating run, gate results, and any operator edits. Raw adapter prompts and responses remain private, but repository reviewers receive enough provenance to judge whether each proposed rule follows from adopted human feedback. + +### Where the mechanism lives + +The tool source, adapter binaries, provider credentials, and intended daily scheduler are kept private to the maintainer's machine rather than committed to this repository. This document specifies the protocol; the reference implementation is private infrastructure. The mechanism serves a single skill maintained by a single operator, so the ongoing cost of vetting mechanism edits through repository review outweighs any provenance benefit. If the mechanism is ever handed off to a second maintainer, that handoff is a follow-up Agent Note that revises this decision — the operator doc at [docs/cookbook/maintaining-dsh-code-review.md](../../../../docs/cookbook/maintaining-dsh-code-review.md) is the entry point for anyone taking over. + +## Alternatives considered + +- **Ship the tool inside this repository.** Rejected for a single-maintainer scope: repository maintenance overhead (typecheck, lint, coverage, cross-cutting refactors) would exceed the value of committed provenance.

Cross-referencing GitHub's PR event stream would tighten this but requires event acquisition beyond the scope of the periodic tool. +- **Two-non-candidate classifications routed to `excluded` without a dispute round.** When both classifiers say "not a candidate" but disagree on which non-candidate reason applies (for example `covered` vs `specific`), the item is excluded rather than re-evaluated. Both classifiers agree the item does not become new reviewer behavior, so a dispute round would not change the outcome. +- **Dual-reviewer independence beyond byte-hash distinctness is a deployment contract.** The tool refuses to run when the two commands resolve to byte-identical executables, but cannot verify that two distinct wrappers back different providers or models.

It collects pre-merge human review feedback with commit anchors (inline comments and review submissions), then compares feedback-time and final landed PR patches. It does not acquire PR conversation comments because current GitHub state cannot give them a force-push-safe feedback-time baseline, and it excludes target-branch-only changes from adoption evidence. +3.

The saved diff, candidate `SKILL.md`, and promotion manifest land under `~/dsh-code-review-outputs/` named by timestamp. The manifest records the source master commit and skill blob, source feedback IDs and URLs, landed evidence ranges, adapter verdicts, and gate results; raw per-adapter I/O stays in a private temp directory whose path is written to the notification and to the daily log under `~/Library/Logs/dsh-code-review-maintainer/`. The maintenance worktree itself is restored clean after every run so the operator is never tempted to edit the maintenance copy in place. + +## What the operator does with a candidate diff + +When a run produces a candidate, a macOS notification arrives with a `dsh-code-review-promote <timestamp>` hint. + +1. **Read the diff on its own merits.** Do not defer to "the reviewers approved" — the maintainer contract is that the operator is the final judgment.

Spot-check at least one candidate: does the linked human comment actually support the added rule? Does the linked PR actually adopt it? + +3. **Decide one of three:** + - **Discard.** Delete the saved candidate. The tool re-considers the same feedback on the next run under whatever the current skill then says. + + ```sh + rm ~/dsh-code-review-outputs/2026-07-16T02-00-00Z.{diff,SKILL.md,manifest.json} + ``` + - **Batch.** Keep the candidate aside if the update is small and could combine with a future one. The source-skill check still applies; rerun the analysis or manually rebase and re-review the diff if `master` changes first. + - **Promote.** From a clean `master` checkout of the repo, run the promote helper. It refreshes `master`, verifies that the current skill matches the recorded source blob, applies the saved diff, and opens a draft PR whose body carries the manifest's provenance summary. It stops on skill drift rather than overwriting newer guidance; the operator still reviews the PR on GitHub and either merges it or closes it. + + ```sh + cd ~/path/to/deepseek-harness # clean master + dsh-code-review-promote 2026-07-16T02-00-00Z + ``` + +4. **Do not commit adapter output verbatim.** Small edits during promotion — tightening wording, removing an example that only makes sense with the source PR's context, folding a rule into an existing one — are expected and preserve the "reviewer judgment" the workflow depends on. Amend the branch before merging. + +## When a run produces no candidate + +That is the common case after every nonempty classification stage has produced at least one valid adapter result. The tool records "no candidate" in its daily log, sends no notification (to avoid alert fatigue), and moves on. Days without a skill update are the workflow behaving correctly, not a stall. + +## Interruptions and handoff + +The mechanism lives on one machine. Interruptions the operator handles as they arise: + +- **Daily run missed.** The two-day overlap window catches one skipped day automatically; longer gaps recover by running the wrapper manually with `DSH_CODE_REVIEW_SINCE=<Nd>`. Overlapping windows are idempotent: guidance already in the current skill is classified `covered` and does not re-enter as a candidate. +- **Adapter provider outage.** The tool refuses to run when the two reviewer commands resolve to byte-identical executables. A single batch whose adapter response fails schema or id validation is failed closed at the batch level (every item in the batch marked unclear) and the run continues; the raw output is preserved for debugging. If either adapter produces no valid result for any nonempty batch in an operation, the run fails, writes a failure record, and notifies the operator; it never collapses a total-provider outage into "no candidate." +- **Handoff to another maintainer.** Open a follow-up Agent Note that supersedes the current one: either move the mechanism into the repository or record the new operator's private setup. Do not silently transfer the tool — the "single-maintainer bus factor" in the Agent Note's Risks section is the reason the handoff needs a documented decision. + +## Where the operator's private setup lives + +The tool source, reviewer adapters, provider credentials, and scheduler are the operator's private infrastructure and are outside this repository by design (see the Agent Note's "Where the mechanism lives" section). This cookbook and the Agent Note describe **what the workflow guarantees**; **how** those guarantees are implemented is a private-infrastructure concern.

Do NOT translate comments inside code blocks. This is a hard rule with no exceptions. -- Inline code spans (commands, flags, paths, API names, version numbers) must be kept verbatim. Never translate or reformat them. -- Every relative link must point to the same target as in the source. Link text is translated; link targets are not. -- Language switcher line: the source document's filename is `{{source_filename}}`. When translating into Chinese, write `[English]({{source_filename}}) | 中文` immediately after the H1 heading. When translating into English, write `English | [中文]({{source_filename_zh}})` immediately after the H1. Emit this line even when the source file has no switcher yet (a brand-new pair); when the source does have one, flip the link direction — never copy it unchanged. -- After a closing bold marker `**`, insert a space before the next character when that character is a Latin letter or digit. Never insert a space before full-width (Chinese) punctuation. +The canonical repository rules below are injected verbatim. Apply every direction-appropriate requirement. In those rules, the authored document is the source for this request and the generated document is its counterpart. -### Tone and Style -- The translation must read as if originally written in the target language by a native speaker. If an expression sounds like a word-for-word rendering from the source language, rephrase it. -- Write in a professional, formal tone appropriate for developer documentation. Never use colloquial or casual expressions. -- Use polite imperative forms where the text instructs the reader to do something. -- Keep the author's register: concise stays concise, detailed stays detailed. +{{translation_rules}} -### Sentence Structure -- Break long sentences with commas or semicolons.

Restructure sentences where the target language grammar requires it. -- Do not invent words or expressions that do not exist in natural technical writing of the target language. +## Request-Specific Structure -### Word Choice -- Prefer precise, formal vocabulary over casual or colloquial alternatives. -- When multiple synonyms exist, choose the one most commonly used in professional technical documentation of the target language. -- Avoid slang, internal jargon, or overly literal translations that would not be recognized by the general developer audience. -- Do not use the same word to translate two different source-language terms that carry distinct meanings. -- Avoid repeating the same verb in close proximity; vary word choice for readability. +- The source basename is `{{source_filename}}`.

Preserve full-width punctuation only in verbatim Chinese text. -- Convert enumeration commas (、) to English commas; convert 「」 quotes to English double quotes. -- Render the terminology table's English column the same way the Chinese column binds the other direction: listed terms use exactly the table's English form; first-occurrence glosses do not carry over (English prose never glosses an English term with Chinese). -- Chinese topic-comment sentences and dropped subjects become explicit English subjects; prefer concise declaratives over nominalizations. -- Do not transliterate Chinese engineering idioms literally: render the underlying concept (误报 → false positive, 执行红线 → enforcement frontier), consulting the terminology table first. -- Keep the register of institutional developer documentation: contractions are acceptable, marketing language and hedging (very, quite, simply) are not. - -## Terminology - -A terminology table is provided below. Follow it strictly: -- Render every listed term exactly as specified. -- First occurrence: write as shown in the "首次出现" column (with parenthetical gloss). Subsequent occurrences: write only the part before the parentheses. -- If a term has already been glossed as part of a compound term, do not gloss it again when it appears alone later. -- NEVER use translations listed in the "不要译作" column. -- For technical terms not in the table: keep them in the source language.

ACP aborted and awaited agents on disconnect but could not unregister just that session's agent; `session/cancel` could not cancel queued-but-not-yet-started work; and `tool-bash` kept task ownership in a plugin-local `Map`, so an HMR reload could make an old task look unowned. - -## Decision - -Three seams: the queue-aware cancel, the `AgentHandle` disposer, and the bash owner token. - -### 1. Queue-aware `Agent.cancel(reason?)` - -`cancel()` is the single public stop primitive. It clears queued and steering input, aborts an in-flight step, and arms a turn-scoped marker checked at each turn boundary. A queued prompt therefore cannot start after cancellation or absorb later input. `whenIdle()` waits for post-cancel quiescence, and ACP `session/cancel` maps to this method. An idle cancel does not arm the marker. - -### 2. `AgentHandle` async disposer - -`ctx.agents.create`/`resume` and `AgentFactory` return `AgentHandle = { agent, dispose() }`. Disposal is a consumer capability; an observer holding only `Agent` cannot tear it down. The caller fiber and factory provider also own the instance, and every path shares one memoized teardown: stop the loop, await quiescence and flushes, detach the agent and session, then unwind its scope. IDs become reusable when their registry entries detach. Config-created agents belong to the loop fiber; ACP stores and disposes each session handle. - -Teardown order is load-bearing for durability. The session lifecycle and loop share one composite Cordis effect so LIFO disposal stops the loop and awaits `agent.done` before detaching the session. Sibling effects would dispose concurrently and could remove append hooks before the closing flush. Disposal notifications are contained so they cannot interrupt the chain. - -### 3. Bash owner token in the seam - -Background task ownership belongs to the executor. `BashExecSpec.owner` carries an optional opaque token, `ownerOf(id)` reads it, and `dsh-tool-bash` stamps the calling session token at start. `bash_output` and `bash_kill` reject mismatched callers; completion notices locate the live agent by session token through the registry. Keeping ownership on the task preserves the fence across tool-plugin reloads. The completion listener remains effect-scoped, so a notice that settles during the reload gap may still be dropped. - -## Verification - -- ACP disconnect or session close leaves no registered agent or session-store entry, including when `session/load` races teardown. -- Cancelling before a queued prompt starts prevents that prompt from running or absorbing the next prompt. -- Reloading `dsh-tool-bash` does not let another session read or kill an existing background task because ownership remains on the executor. -- Config-created agents remain loop-fiber-owned, so non-ACP demos need not manage handles explicitly. - -## Session owner tokens are unique among live agents - -The bash owner token relies on `session.header.id` being unique among live agents. Concurrent same-ID operations may prepare privately, but `SessionStore.enter()` rejects duplicate publication and the losing transaction rolls back. `tool-bash` owns the comparison policy; the bash seam stores an opaque `owner` string without interpreting it. - -## Alternatives considered - -- **A public `BashTask.owner` field** instead of the `BashExecutor.ownerOf(id)` seam — rejected: one read path, no redundant API. -- **Sibling cordis effects for the agent's session lifecycle** — rejected: a fiber unload disposes sibling effects concurrently (`Promise.all`), racing removal of the store-owned append publication hooks against the loop's closing `session/flush`; the single composite effect's ordered LIFO chain is what captures the closing `turn/end` on both disposal paths. -- **A separate step-only `abort()` beside `cancel()`** — shipped originally, then removed as unused; `cancel()` is the single public stop primitive ([the public-stop-surface RFC](../simplification/2026-06-20-public-agent-stop-surface.md)). - -## Consequences - -This touched public interfaces (`Agent`, `AgentFactory`, the bash seam) deliberately, not as a local ACP patch.

Two gaps let a structurally-identical-but-semantically-wrong string slip through the type checker today. - -**Gap 1 — unbranded IDs in the bash seam.** `BashTask.id` and every executor/tool boundary used bare `string`, even though the generated value has the same `name-N` shape as default session ids.

It is compared for access control (`owner !== callerToken(exec)`), so a mismatched-but-well-typed string here is a cross-session isolation bug the type system currently cannot catch. This is the same `session.header.id`-as-owner alias that the [unify-the-agent-id-and-the-session-id](../../proposed/simplification/2026-06-20-unify-agent-and-session-id.md) proposal calls the "bash owner-token alias hole". - -**Gap 2 — erosion of existing brands.** `CallId`, `SessionId`, and `AgentId` became bare strings in registry maps, public lookup parameters, ACP session tracking, and the persistence coordinator.

Brands are zero-cost casts; nothing about runtime behavior, serialization, comparison, or the wire format changes. The work is in three parts, all honoring the existing "not every string" policy. - -- **Brand the bash task id.** Add `BashTaskId = Branded<'BashTaskId'>` plus its same-named factory in `packages/bash/bash/src/types.ts` (the package that *owns* the id), importing `Branded` from `@deepseek-ai/dsh-brand` exactly as `SessionId`/`AgentId` already do. The brand primitive lives in the dependency-free `dsh-brand` utility package precisely so `dsh-bash` can brand its ids by depending on it alone — it never pulls in `dsh-llm` (or `dsh-session`) just to reach `Branded`. Thread it through `BashTask.id`, the `BashExecutor` seam methods (`get`/`ownerOf`/`readOutput`/`kill`), the generation site in `dsh-bash-local` (brand the counter output once, at creation), and the `dsh-tool-bash` validate/access surface (`validateTaskId` returns a `BashTaskId`; `task_id` is branded at the tool boundary where the model's string arrives). - -- **Mint a distinct `OwnerToken` brand.** Add `OwnerToken = Branded<'OwnerToken'>` in `packages/bash/bash/src/types.ts`; type `BashExecRequest.owner` / `BashExecSpec.owner` / `BashExecutor.ownerOf` as `OwnerToken | undefined`. The `dsh-tool-bash` consumer casts the agent's `session.header.id` (a `SessionId`) into an `OwnerToken` at the boundary — the one place the two vocabularies meet. The bash seam never imports `dsh-session`. (Rationale in the next section.) - -- **Stop the brand erosion.** Propagate the existing brands to the `Map` key types and public method params listed under Gap 2 — `Map<SessionId, Session>`, `get(id: SessionId)`, `Map<AgentId, Agent>`, `Map<CallId, …>`, the ACP `SessionRecord.sessionId: SessionId` surface, the coordinator's `Map<SessionId, …>`. This is the larger mechanical share of the diff and the part that makes the *existing* brands actually load-bearing on lookups, not just on the struct fields. - -Illustrative shape (the factory pattern is identical to the three existing brands): - -```ts ignore-check -import type { Branded } from '@deepseek-ai/dsh-brand' - -/** A background bash task handle (generated `bash-N` by the local executor). */ -export type BashTaskId = Branded<'BashTaskId'> -export function BashTaskId(id: string): BashTaskId { - return id as BashTaskId -} - -/** A bash task's opaque isolation key — the consumer's owner identity, NOT the bash seam's. */ -export type OwnerToken = Branded<'OwnerToken'> -export function OwnerToken(id: string): OwnerToken { - return id as OwnerToken -} -``` - -## Alternatives considered - -### Why not typing `owner` as `SessionId`? - -The executor treats ownership as opaque and must not depend on the session model. A distinct `OwnerToken` preserves that boundary while preventing raw strings or task ids from being passed as owners. `dsh-tool-bash`, which owns the access policy, performs the single conversion from `SessionId`. - -## Out of scope / possible extensions - -Kept deliberately narrow per the "not every string needs a brand" policy. Each of these is a plausible future brand, deferred with a reason, not a commitment: - -- **`ModelId`** (`GenerateOptions.model`, the `LlmService` adapter-registry key) — a real cross-package lookup key (config → agent → llm → adapter); a reasonable next brand, left out only to keep this RFC's blast radius focused. -- **`ToolName`** (the `ToolRegistry` key) — author-defined, human-readable, and rarely confused with another id; the weakest candidate, likely not worth a brand. -- **`ErrorCode`** (`HarnessError.code`) — a closed vocabulary (`ABORTED`, `NO_ADAPTER`, …), not a per-instance id; better served by a string-literal union than a brand, if anything. -- **Numeric ordinals** — turn number, step number, and the event `seq` are `number`, not `string`, so `Branded<string>` does not apply; a parallel `number & { readonly [BRAND]: B }` variant could brand them, but they are positional ordinals rarely passed across boundaries, so the payoff is low. -- **Validated construction** — the brand factories are pure casts with no runtime check, and every boundary (ACP `sessionId`, provider-issued `call.id`, the empty-string fallback in `dsh-llm-deepseek`) trusts the raw string today. A `SessionId.parse()` / `isValid()` companion that throws on malformed input at boundaries is a genuine gap, but it is a *runtime-behavior* change with its own design (what is "malformed"? what do we do on failure?) and belongs in its own RFC, not bundled into this type-only pass. - -## Verification - -`BashTaskId` and `OwnerToken` are defined in `dsh-bash` and threaded through the executor, local implementation, and model-facing tool without adding a `dsh-session` dependency. Collections, public parameters, and exported signatures use the applicable brand for `CallId`, `SessionId`, `AgentId`, or `BashTaskId` rather than bare `string`; raw provider, ACP, and model inputs enter through the brand factory instead of scattered casts. - -## Consequences - -- **Mechanical churn across two surfaces.** Propagating brands touches the bash seam (interface + impl + consumer) and the ACP session-id surface plus the persistence coordinator. The churn is broad but low-severity: a missed site is a compile error, not a silent bug. The change is observably type-only — no snapshot or e2e behavioral diff. It sits next to the [unify-the-agent-id-and-the-session-id](../../proposed/simplification/2026-06-20-unify-agent-and-session-id.md) proposal (both touch the session-id / owner-token boundary); if that proposal lands, `OwnerToken` still stays distinct from the unified id for the decoupling reason above. -- **Brands do not validate.** A brand is a confusability guard, not a correctness proof: a *wrong* session id that is still a well-formed string passes the type checker exactly as before. This RFC does not close that gap (see Out of scope) — it only stops the *category* error of passing the wrong *kind* of id. -- **The "where to stop" line stays a judgment call.** Branding `BashTaskId` but not `ToolName`, `OwnerToken` but not `ModelId`, is a taste call about which strings "could plausibly be confused." Reasonable reviewers may want more or fewer; the policy in `brand.ts` is the tie-breaker, and this RFC errs toward the ids that are model-facing or used for access control. diff --git a/docs/rfc/implemented/feature/2026-06-18-compaction-capability-seam.md b/docs/rfc/implemented/feature/2026-06-18-compaction-capability-seam.md deleted file mode 100644 index 4a6586b159..0000000000 --- a/docs/rfc/implemented/feature/2026-06-18-compaction-capability-seam.md +++ /dev/null @@ -1,125 +0,0 @@ -# RFC: Compaction as a capability seam (abstract contract + basic backend) - -Status: implemented - -## Problem - -A long-running agent conversation grows without bound. As the event log accumulates turns, the derived message history eventually approaches the model's context window — the model then truncates mid-response (`max-tokens`) or degrades. **Compaction** is the mitigation: replace a run of older history with a concise summary, keeping recent context intact. - -The [session surface](../../implemented/architecture/2026-06-18-session-surface.md) was built as the foundation for exactly this — a linked list over the event log with a `surfaceOp: { op: 'replace', start, end }` operation purpose-built to shadow a range of nodes and insert a replacement, with `sourceEventSeqs` recording provenance so the decision replays deterministically. What remained was the plugin that *decides what to compact and produces the summary*. - -Two forces shape the design. First, compaction is **swappable**: token counting can be a char/4 heuristic or a real tokenizer, and summarization can be a model call, a template, or a remote service — these vary independently of *when* and *which range* to compact. Second, `SurfaceEventType` is closed to five event types (`user/message`, `assistant/message`, `tool/result`, `context/message`, `steering/message`); only those may carry `surfaceOp`. A bespoke `compaction/*` event therefore **cannot** itself appear on the surface — the compiler rejects `surfaceOp` on it and the invariants plugin rejects it at runtime. - -## Decision - -### Compaction is a capability seam, split interface / implementation - -Per the [capability-seams RFC](../../implemented/architecture/2026-06-13-capability-seams.md), compaction ships as separate packages so the contract, the algorithm, and (later) the consumer surface evolve independently: - -1. **Interface** — `@deepseek-ai/dsh-compact`: an abstract `CompactService` owning the `ctx.compact` key, the `CompactionResult` vocabulary, and the `compact/*` session events. It declares `compactIfNeeded()` and `compactRegion()` as **abstract** — the contract states *what* compaction does, not *how*. -2. **Implementation** — `@deepseek-ai/dsh-compact-basic`: a concrete `BasicCompactService` that owns the entire algorithm — token estimation (chars per token — the `charsPerToken` config, default 4 — + per-block overhead), the tail→head retention walk, summarization via `ctx.llm.stream()`, the surface replacement, the lock, and the `agent/pre-step` auto-compaction listener. A tokenizer-based or template-based backend is a sibling package (or a subclass overriding the two protected estimation/summarization hooks). -3. **Consumer** — deferred. A `/compact` tool and slash command will `inject: ['compact']` and call the contract; they are intentionally out of scope here so the seam settles first. - -### The contract depends on `dsh-session` and `dsh-llm` — a deliberate deviation - -The capability-seams RFC states the interface package "depends only on cordis" (true of `dsh-bash`, whose vocabulary is self-contained). Compaction **cannot** honor that: its verbs are defined *over* a `Session` (`compactRegion(session, start, end)`) and its output *is* the content vocabulary (`CompactionResult.summary: ContentBlock[]`). There is no way to express the contract without naming `Session`/`SessionEvent` (from `dsh-session`) and `ContentBlock` (from `dsh-llm`). - -This is not a coupling smell — it is the contract's domain. The "only cordis" guidance was always shorthand for "the interface depends only on what the contract genuinely names, and never on an implementation." `dsh-session` and `dsh-llm` are themselves interface/vocabulary packages, not implementations; `dsh-compact` still imports no backend. The seam's real invariant — *consumers and implementations evolve independently behind an abstract service* — holds intact. - -### Abstract `compactIfNeeded` / `compactRegion`, algorithm in the backend - -An earlier draft put the full algorithm (the retention walk, token-summing, text extraction) as concrete methods on the interface, with only `estimateContentTokens()` and `summarize()` abstract. That recouples the contract to one strategy: a backend that wants a different retention policy or a different event-sequencing would have to fight inherited concrete code. Making both core methods abstract puts every *how* decision in the backend, where it belongs, and keeps the interface a pure statement of *what*. The backend remains internally factored — `estimateContentTokens()` and `summarize()` are `protected` hooks a sub-backend can override without reimplementing the walk — but that factoring is the backend's private concern, not the contract's. - -`compactIfNeeded(agent, turn, step, fullSystemPrompt, signal)` takes **required** parameters (not the original all-optional shape). The auto-compaction seam (below) always supplies the agent, lifecycle context, assembled system prompt (counted toward the estimate), and the turn's abort signal, so optionality would only invite a hidden default at the seam. The session being compacted comes from the agent context. `compactRegion(session, start, end, agent, turn, step, signal?)` keeps an optional signal (a manual caller may omit it). Passing lifecycle context rather than a concrete model keeps router agents honest: the backend's summarization request can run through `agent/request`, where model-routing plugins already choose the actual model. - -### Auto-compaction runs on `agent/pre-step`, a dedicated surface-mutation seam - -Compaction mutates the session surface, so it runs before the step opens and before messages are derived. `agent/request` remains a call-config transform and never needs to rebuild history after a surface change. - -The fix is a dedicated loop seam, **`agent/pre-step`** (`@mode serial`), fired by the loop *after* system assembly and *before* the step opens (`step/start`): - -``` -assembly = ctx.systemPrompt.assemble() -await ctx.serial('agent/pre-step', agent, turn, step, system, signal) ⟵ compaction mutates the surface here -session('step/start') ⟵ the step opens AFTER the seam -messages = session.deriveMessages() ⟵ single derive, reflects the compaction -request = waterfall agent/request ⟵ pure request transform (hooks, model switch) -``` - -The loop derives messages once after `agent/pre-step`. Running before `step/start` keeps compaction records outside any half-open step, simplifying crash repair. The seam is awaited and serial so surface mutations cannot interleave; listeners return `void` and do not use Cordis bail values as vetoes. - -### Retention is turn-agnostic; tool-pairing balance is the only structural guard - -Auto-compaction fires before **every** step, not once per turn. This is **load-bearing for runaway-turn survival**: a tool-heavy ReAct turn appends an `assistant/message` + a `tool/result` per step, so the surface grows *within* a turn. A single turn can grow past the window on its own (a "runaway turn") — and the only moment to rescue it before the next model call overflows is the next step's `pre-step` checkpoint. Gating compaction to a turn's first step (or, worse, retaining the whole in-flight turn verbatim) re-opens exactly the hole compaction exists to close: the harness would die when compaction is most needed. - -`compactIfNeeded` retains the smallest tail of whole surface units whose estimated size reaches `retainTokens` and compacts older nodes. A unit is a complete closed step or one no-step message. If the token cutoff lands inside a step, retention expands until the cut is tool-pairing balanced. Balance is checked on surface order, not log sequence, because replacement summaries have new sequence numbers at old surface positions. `compactRegion` rejects boundaries that split a tool call from its result. The in-flight turn receives no special retention. - -A runaway turn thus compacts exactly like any other history: its early *closed* steps get summarized while its recent steps stay verbatim. When the only compactable content left is an un-splittable open tail step (its tool-calls have no results yet), compaction declines (`null`) and retries once that step closes. - -**Single-unit overflow is out of scope, by design.** If a single retained unit — one closed step, or a large free node such as a pasted `user/message` — *alone* exceeds the budget, compaction cannot help and the next model call may go out over-budget. Bounding an individual unit's size is a separate concern (output truncation), handled elsewhere; compaction makes no promise about it, and the harness without such a mechanism can still break on a single oversized unit. This is named honestly rather than papered over. - -### Head-anchoring: one auto checkpoint, always at the head - -Auto-compaction always starts at the surface head, merging the prior checkpoint with newly compacted history so only one automatic checkpoint remains. `shadowedRange` is therefore positional rather than a numeric sequence interval: a newer summary sequence may occupy an older surface position. `shadowedSeqs` records the authoritative surface order. Manual mid-range compaction may leave multiple checkpoints. - -### Approximate convergence invariant - -`resolveConfig` validates numeric knobs but does NOT reject based on a pretend summary-length invariant. Convergence is dynamic: provider output caps can be spent on hidden or surfaced reasoning tokens, and the model may emit a summary of unpredictable size. `maxTokens` is only the provider-side generation cap for the summarization call; reasoning blocks are stripped before the checkpoint is stored. If a compacted surface is still over threshold, `compactIfNeeded()` re-compacts the head checkpoint up to `compactionRetries` extra times, but each committed summary must be smaller than the content it shadows. The sole residual is the single-unit-overflow case above (a backward-rounded oversized step can push the retained tail over budget) — which is exactly the out-of-scope concern, not a thrash bug. - -### Surface replacement: `compact/*` events are log-only; one `user/message` carries the summary - -Because `SurfaceEventType` is closed, the summary cannot ride on a `compact/*` event. The backend instead appends a **single `user/message`** with `surfaceOp: { op: 'replace', start, end }` whose `content` is the (framed) summary and whose `sourceEventSeqs` covers the shadowed nodes *and* the bookkeeping events. The `compact/*` events are pure log records (lock + provenance). The surface mutation sits **inside** the lock — `compact/end` is the last event appended: - -``` -compact/start → log-only. Acquires the lock. -[summarize older range via the backend] -compact/summary → log-only. Provenance: raw summary, range, shadowed seqs, token count. -user/message → surfaceOp { op:'replace', start, end }. THE surface mutation (framed summary). - deriveMessages() renders it as a user-role message. -compact/end → log-only. Releases the lock (carries `error` on a recoverable failure). -``` - -`deriveMessages()` then yields `[summary_as_user_message, ...retained_nodes]`. Reusing `user/message` is honest rather than a workaround: a summary genuinely *is* user-role context. - -### Checkpoint framing + incremental merge (backend-private) - -The basic backend wraps the summary as established checkpoint context and tags it for incremental merging on the next cycle. The raw summary remains on `compact/summary`. Framing is backend policy; the seam promises only that one replacement user message carries the possibly framed summary. - -### Blocking via a log-recorded lock, plus a crash/recoverable failure taxonomy - -The `compact/start … compact/end` bracket is justified, in order of what now does the work: - -1. **Crash-detectable orphan + provenance** (primary). Summarization is a slow model call persisted *after* `compact/start`. A crash mid-summarization leaves a `compact/start` with no matching `compact/end` — a detectable orphan. Releasing the lock last (rather than first) converts the crash window from *silent corruption* into that detectable orphan. -2. **Prevents concurrent compaction.** `compactRegion` refuses to start if the current turn holds an unmatched `compact/start`. (The loop is single-threaded across the awaited `pre-step`, so this is also a re-entry tripwire — a thrown "already in progress" signals a real bug.) - -Two failure paths, both documented: - -- **Crash** (the loop dies mid-summarization): a dangling `compact/start`, no closer. Because `compact/*` are **log-only**, the orphan is **inert** — the surface replacement never landed, so the full, uncompacted history derives correctly. Generic turn-repair (`interruptedTurnClosers`) closes the turn with a synthetic `turn/end`; the orphan sits *before* that `turn/end`, so the turn-scoped in-progress check never sees it and a crash can't wedge future compaction. Compaction simply re-attempts at the next `pre-step`. -- **Recoverable** (summarization throws but the loop survives): the backend appends `compact/end` with its **`error`** field set, leaving the surface untouched, and the model call proceeds with full history. - -`compact/end` keeps its `error?` field (mirroring `tool/result`'s self-contained error — one event tells success from failure without correlating a sibling). There is no separate `compact/error` event. - -**Core session repair stays compaction-agnostic — deliberately.** `interruptedTurnClosers` is never taught about `compact/*`. Teaching it would force every future `xxx/start … xxx/end` plugin pair to patch a core module — exactly the coupling the capability-seam architecture exists to avoid. Because the log-only orphan is inert, no special repair is needed: generic turn-repair plus the inertness of an un-landed surface mutation is sufficient. - -## Alternatives considered - -- **The full algorithm as concrete interface methods** (only estimation/summarization abstract) — the earlier draft; rejected because it recouples the contract to one retention strategy. Both core methods are abstract; the `protected` estimation/summarization hooks are the backend's private factoring, not the contract's. -- **Compaction on the `agent/request` waterfall** — the earlier cut; rejected for the double-derive it forced and for handing the listener context it structurally cannot compact. The dedicated `agent/pre-step` seam makes the layering correct by construction. -- **A separate `compact/error` event** — rejected: `compact/end` keeps an `error?` field, mirroring `tool/result`'s self-contained error — one event tells success from failure without correlating a sibling. -- **Teaching core turn-repair about `compact/*`** — rejected: the log-only orphan is inert, and a core module patched for every future `xxx/start … xxx/end` plugin pair is exactly the coupling the capability-seam architecture exists to avoid. - -## Consequences - -- **New packages**: `packages/compact/compact` (interface) and a sibling `compact-basic` (backend) under `packages/compact/`, wired into the root tsconfigs. The consumer tier is deferred. -- **New loop seam**: `agent/pre-step` (`@mode serial`) declared in `dsh-agent` and emitted by `dsh-agent-loop` after system assembly and before `step/start`. This is a documented change to the loop — `docs/architecture.md` records it and the generated cordis catalog carries its signature. -- **`SessionEventMap`** gains `compact/start` / `compact/summary` / `compact/end` by declaration merging (merge-extensible); `SurfaceEventType` is **not** touched. These are session events, not cordis `Events`, so the event-taxonomy gate needs no entry. -- **`dsh-session`** gains the tool-pairing balance predicate (`isToolPairingBalanced`, in `tool-pairing.ts`, exported from the package index) that `compactRegion`/`compactIfNeeded` use to keep a collapsed region from splitting a step's tool-call/result pair. The surface `replace` op and the surface-metadata runtime guard already existed and are reused. -- **`dsh-invariants`** drops its `surface replace: start must be <= end` assertion: a head-anchored compaction lands a high-seq replacement node at an older range's *position*, so `start > end` numerically is normal and valid (the range is positional, validated by the surface's `indexOf` checks that remain). The turn-enclosure invariant is reused unchanged. -- **Wiring**: `dsh-compact-basic` is loaded in `examples/coding-agent`'s `cordis.yml`, so the seam ships in the real demo (it was previously loaded nowhere). - -## Testing - -- **Unit:** Real Loader and invariant plugins cover whole-unit retention, convergence failure, both `compact/end` outcomes, head anchoring, open-tail refusal, inert crash orphans, and compacting closed steps inside one oversized open turn. -- **Loop:** Tests pin one awaited `agent/pre-step` per step between `turn/start` and `step/start`; a surface mutation there lands outside the step and appears in the single derived request. -- **With-key e2e:** A real model and bash session with lowered limits triggers compaction, records a complete `compact/start…end` pair, shrinks the surface, and finishes the task. -- **Snapshot gap:** Runaway-turn compaction cannot yet replay because the summarization call records no `assistant/chunk` events or `sessionId`; interleaved summarization-call replay remains follow-up work. diff --git a/docs/rfc/implemented/feature/2026-07-07-session-prefix.md b/docs/rfc/implemented/feature/2026-07-07-session-prefix.md deleted file mode 100644 index f0d458368a..0000000000 --- a/docs/rfc/implemented/feature/2026-07-07-session-prefix.md +++ /dev/null @@ -1,42 +0,0 @@ -# RFC: The session prefix — request-only messages in front of the derived history - -Status: implemented - -## Problem - -A plugin often owns a session-stable opener the model must always see — a skills catalog, an AGENTS.md digest, a workspace baseline.

A process restart or `ctx.agents.resume()` is a new instance: it recomposes, and any drift lands attributably on the `'resume'` header snapshot. This is the routing rule the seam creates: session-frozen openers ride the prefix; content that changes mid-session rides the append-only history channels (`agent.inject()`, a `tools/post-execute` decision's `additionalContext`, prompt-submit `additionalContext` — [the interception-seams RFC](2026-06-30-interception-seams.md)), each a durable `context/message` paid once and prefix-cached thereafter. -- **Composed before the pressure gate.** Composition precedes the instance's first `agent/pre-step`, and the seam hands the composed value through: `agent/pre-step` carries a `sessionPrefix` parameter and `CompactService.compactIfNeeded(agent, fullSystemPrompt, sessionPrefix, signal)` counts it in its token-pressure estimate — a gate reading the previous instance's folded prefix instead would under-gate a resumed or forked instance whose contributor grew, skipping compaction and shipping an over-window first request.

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:<id>]`, 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. */ cordis_mount(args: { @@ -72,19 +66,41 @@ declare const tools: { /** The exact skill name from the available skills list. */ name: string; }): Promise<string>; - /** Delegate a self-contained task to a subagent (a separate agent that works in its own context) and return its final result.

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> 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`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access.

Statuses: `pending` (not started), `in_progress` (being worked on now), `completed` (finished). */ + todo_write(args: { + /** The COMPLETE task list, replacing any previous list. */ + todos: ({ + /** What the task is — a short imperative line. */ + content: string; + /** pending (not started) | in_progress (now) | completed (done). */ + status: "pending" | "in_progress" | "completed"; + })[]; + }): Promise<string>; + /** Run a JavaScript workflow script that orchestrates subagents at scale. 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 <value>` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise<any>` — 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<any[]>` — 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<any[]>` — 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 <json-value>`). */ + script: string; + /** The workflow identity block (plain JSON — never code). */ + meta: { + /** Short kebab-case workflow name. */ + name: string; + /** One-line description of what the workflow does. */ + description: string; + /** Optional guidance on when this workflow applies. */ + whenToUse?: string; + /** Optional phase declarations matched by phase() calls. */ + phases?: { + /** The phase title phase() calls match by exact string. */ + title: string; + /** Optional one-line description of the phase. */ + detail?: string; + /** Optional provider override this phase is expected to use. */ + provider?: string; + /** Optional model override this phase is expected to use. */ + model?: string; + }[]; + }; + /** Optional JSON input exposed to the script as the `args` global (wrap a bare list as a field, e.g. {"files": [...]}). */ + args?: Record<string, unknown>; + }): Promise<string>; + /** Create or fully replace a UTF-8 text file. */ + write(args: { + /** Path to write, resolved by the filesystem backend. */ + file_path: string; + /** Full UTF-8 text content to write. */ + content: string; + }): Promise<string>; +} +``` diff --git a/examples/acp-agent/tests/snapshots/code-mode-workspace-context/tool-schemas.expected.json b/examples/acp-agent/tests/snapshots/code-mode-workspace-context/tool-schemas.expected.json new file mode 100644 index 0000000000..c2289b4e19 --- /dev/null +++ b/examples/acp-agent/tests/snapshots/code-mode-workspace-context/tool-schemas.expected.json @@ -0,0 +1,21 @@ +{ + "initial": [ + { + "name": "run_code", + "description": "Execute a TypeScript program against the available tools.

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 <value>` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise<any>` — 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<any[]>` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`.

Set `run_in_background: true` for long-running commands: the call returns a task id immediately; poll it with `bash_output` and stop it with `bash_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`.

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 <value>` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise<any>` — 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<any[]>` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`.

Use current-consumer evidence or relevant prior art; otherwise require an explicit value or defer the choice. +- **Write model-facing contracts from the model's perspective.** Prompts, tool schemas, results, and diagnostics contain only task-relevant concepts, not UI, transport, or implementation vocabulary.

All four surveyed tools spawn per call. `XXX(stateful-shell)` in `src/run.ts` records the two proven stateful designs (Claude Code's cwd-only persistence; Codex's PTY exec sessions) for when real workflows demand them. -- **Process-group kills with escalation** — children are spawned `detached` (own process group); kills send SIGTERM to the group, then SIGKILL after the `graceMs` grace (default 3s — OpenCode's escalation; pipelines and subshells die with the parent). ESRCH is tolerated; daemons that re-parent away from the group can still survive — same caveat as the surveyed tools. -- **Tail-keep truncation + spill files** — output beyond `maxOutputBytes` keeps the in-memory TAIL (errors/results cluster at the end — pi/OpenCode rationale) while the FULL stream is appended to a temp file whose path is reported when available. If the final spill close reports a delayed writeback failure, the executor still returns the tail but withholds the path rather than advertising a possibly incomplete file. -- **Model-friendly environment** — ambient credential-shaped variables are removed before noninteractive terminal defaults and explicit caller entries are applied. Supplied stdin is written and closed; otherwise fd 0 is `/dev/null`. Trusted plugins use `env` and `stdin`, but the model-facing tool does not expose them. See the [bash stdin/env RFC](../../../docs/rfc/implemented/architecture/2026-06-30-bash-stdin-env-trusted-plugin-surface.md). -- **Background tasks** — `start()` returns immediately, no timeout applies (Claude Code detaches timeouts when backgrounding), `readOutput()` is incremental with whole-stream byte offsets, and disposal kills everything. The spec's opaque `owner` token is stored on the tracked task and returned by `ownerOf(id)` — the executor never interprets it (the consumer's access policy does), and because it lives with the task here it survives a `tool-bash` HMR reload. +- **Process-group kills with escalation** — children are spawned `detached` (own process group); kills send SIGTERM to the group, then SIGKILL after the `graceMs` grace (default 3s — OpenCode's escalation; pipelines and subshells die with the parent). After the main shell exits, inherited stdout/stderr pipes receive the same bounded drain grace so a surviving descendant cannot hold the command open indefinitely. ESRCH is tolerated; daemons that re-parent away from the group can still survive — same caveat as the surveyed tools. +- **Tail-keep truncation + bounded spill files** — output beyond `maxOutputBytes` keeps the in-memory TAIL (errors/results cluster at the end — pi/OpenCode rationale) while the FULL stream is appended to a temp file whose path is reported when available. A foreground `BashExecRequest.stdoutMaxBytes` can raise stdout's capture budget for one trusted caller; stderr and background tasks still use `maxOutputBytes`. A stream larger than `maxSpillBytes` discards its now-incomplete spill and returns only the marked truncated tail. If the final spill close reports a delayed writeback failure, the executor likewise withholds the path rather than advertising an incomplete file. +- **Model-friendly env + credential scrub** — `process.env` minus credential-shaped vars (`*KEY*`/`*SECRET*`/`*TOKEN*`) and all ambient `DSH_*` names, then `NO_COLOR=1 TERM=dumb PAGER=cat GIT_PAGER=cat` (Codex's hardcoded set) so pagers and ANSI color don't garble results. A spec's ordinary `env` is merged after the scrub but rejects `DSH_*`; managed `dshEnv` rejects ordinary names and merges last, preventing stale nested-harness identity.

The foreground path re-throws it as the structured fail-closed `SANDBOX_UNAVAILABLE` error, with the runner's first stderr line as the cause; a settled background task stamps `task.sandbox.runnerFailed` instead (no error channel remains after settle), which `bash_output` renders as its own marker. -- **Config default, per-call override.** `resolve()` stamps the configured sandbox mode onto each spec unless an approved request supplies a wider mode.

The capability fact `ctx.bash.sandboxMode` reports the configured default so the tool layer advertises escalation only when this executor is mounted.

Foreground `run` returns exit, timeout, cancellation, output, and optional sandbox facts; background `start` and `readOutput` use task records. A sandboxing executor reports the executed mode, conservative denial classification, and enforcement completeness. See [core-data-structures/bash.md](../../../docs/core-data-structures/bash.md) for full shapes. +The seam also owns the per-session mode override vocabulary: the log-only `'bash/sandbox-mode'` session event, the pure `effectiveSandboxMode(events)` fold, and the `setSandboxMode(session, mode)` write path. `run()` returns `BashRunResult`; `start()` returns `BashProcess`, whose incremental read and kill methods are adapted by `dsh-tool-bash` into a generic task registration. A sandboxing executor stamps `BashSandboxInfo` on foreground results and settled process handles. See `src/types.ts` and [core-data-structures/bash.md](../../../docs/core-data-structures/bash.md). -`stdin` and `env` are set by in-process plugins (the hooks bridges, native plugins) to feed a hook command its JSON payload on stdin and its `CLAUDE_PROJECT_DIR`/`CLAUDE_PLUGIN_ROOT` env. The model-facing `dsh-tool-bash` tool does not expose them as parameters — a model already has equivalent power through shell syntax (`FOO=bar cmd`, a heredoc), so they would be redundant tool params. This is not a security boundary: the implementation's credential scrub (not these fields) is what keeps the harness's ambient secrets out of a spawned command. They are plain optionals on the resolved spec (unlike `owner`'s required-but-nullable): a missing one means "none", the safe default. See [the bash-stdin-env RFC](../../../docs/rfc/implemented/architecture/2026-06-30-bash-stdin-env-trusted-plugin-surface.md). +`stdin` and ordinary `env` are set by in-process plugins (the hooks bridges, native plugins) to feed a hook command its JSON payload and `CLAUDE_PROJECT_DIR`/`CLAUDE_PLUGIN_ROOT` values. `dshEnv` is a separate trusted overlay restricted by type to managed keys; the exported `DSH_ENV_PREFIX` is the single source for that namespace, its `DshEnvironmentKey` template type, executor scrubbing, registry validation, derived built-in names, and model guidance. Model bash uses the current snapshot collected by `ctx.bashEnv`. Implementations remove inherited managed keys, reject those names in ordinary `env`, then merge `dshEnv`, so an omitted current fact cannot fall back to stale ambient state. The model-facing tool exposes none of these as parameters. All three remain optional on the resolved spec; absent means no input/overlay.

The local executor removes all inherited `DSH_*` before merging that snapshot, so nested harnesses and concurrent parent/child agents cannot leak stale identities. `process.env` is never modified. The tool description teaches the generic `$DSH_*` convention rather than naming persistence-specific variables or adding a permanent system-prompt section. + Result text contains stdout, an optional `[stderr]` section, then applicable sandbox-denial, timeout, signal, exit-code, and truncation markers. Timeout is reported independently of final exit status; nonzero exit remains a model-interpreted result rather than `isError`. Truncation links a safe complete spill file or reports it unavailable. Only infrastructure failures such as spawn errors and aborts produce `isError`. -### `bash_output` - -`task_id` → output produced **since the previous `bash_output` call** plus a status line (`running` / `completed, exit code: N` / `killed`). A settled task classified as a sandbox denial carries the same `[sandbox: file access denied under <mode> mode]` marker on every read that sees it (denials are only classifiable once the whole stderr has been collected). Reads that lost data to buffer bounds say so and point at the full-output spill file when one is safely available, otherwise `(unavailable)`. - -### `bash_kill` - -`task_id` → ask the executor to kill the background task. The concrete executor decides how to signal or stop the process; killing an already-finished task is a reported no-op, and unknown ids are errors. - -### Task ownership (cross-session isolation) - -The executor stores the spawning session id as the task's owner. `bash_output` and `bash_kill` reject a caller with a different session id; agent-less tasks remain unowned, while agent-less calls cannot access owned tasks. Storing ownership on the task prevents predictable global ids from crossing ACP sessions and preserves the fence across tool-plugin reloads. Completion notices remain effect-scoped and may be missed during a reload gap. +When `run_in_background` is true, this plugin preflights `ctx.tasks.start()` before spawning, registers the calling agent as owner, and adapts the returned `BashProcess` handle into generic cancel/done/incremental-output hooks. The task runtime owns ids, cross-session isolation, completion notices, waiting, and disposal cleanup; this plugin only maps bash exit/sandbox facts into task output and outcome detail. `enableRunInBackground: false` removes the parameter and rejects a forced background call at execution time. ## UI presentation -UI presentation is tool-owned through `presentCall` and `presentResult`. Foreground `bash` uses a terminal card whose title is the exact command and whose optional description is separate; cwd follows an explicit `workdir`—resolved by the bridge against the session when relative—or the session cwd. Its result carries raw output plus exit or signal data, and clients without terminal support receive a bridge-derived fenced console fallback. Background runs, spawn failures, `bash_output`, and `bash_kill` use generic cards. Presenters are pure and replay-safe; malformed older arguments fall back to generic rendering. See [`dsh-tools`](../../core/tools/) and [`dsh-acp`](../../ui/acp/) for card semantics. - -## Background completion notices - -When a task finishes, the plugin resolves its owner token to a live agent and injects a durable completion notice. If the owner no longer exists, the notice is dropped. Injection affects the next request but does not wake an idle agent, so the model must poll with `bash_output` when it needs completion promptly. +The tool owns its `presentCall`/`presentResult` render intent. A foreground call is a terminal card carrying command, description, cwd, raw output, and parsed exit status. A background start is a generic execute card because it returns only a task id; the generic `task_*` tools own their own cards. These presenters are pure and replay-safe. ## The tool builds its request from named args only -The seam supports trusted-plugin `stdin` and `env`, but the model-facing tool does not. It builds requests only from its declared arguments, signal, and owner; extra model keys are ignored. Shell syntax already provides equivalent command-level behavior, while the local executor's credential scrub protects ambient secrets. See the [stdin/env RFC](../../../docs/rfc/implemented/architecture/2026-06-30-bash-stdin-env-trusted-plugin-surface.md). +The `BashExecRequest` seam carries optional `stdoutMaxBytes`, `stdin`, ordinary `env`, and managed `dshEnv`, used by trusted in-process plugins and this tool's environment registry. The model-facing tool exposes none of `stdoutMaxBytes`, `stdin`, or `env`: it builds requests from named command/workdir/timeout/signal/sandbox fields plus the registry-collected `dshEnv`. Extra model keys are ignored and cannot replace managed values. Shell syntax provides equivalent command-level behavior, while the local executor scrubs ambient credentials and stale `DSH_*` values. See the [stdin/env Agent Note](../../../.agents/notes/implemented/architecture/2026-06-30-bash-stdin-env-trusted-plugin-surface.md). ## Permissions and escalation Commands run with the executor's full authority unless a sandboxing executor ([`dsh-bash-sandbox`](../bash-sandbox/)) confines them — the deny-only sandbox reports denials as result facts, rendered here as the denial marker; per-call allow/deny/ask policy is the `tools/pre-execute` waterfall (see docs/architecture.md). -Escalating bash calls resolve `ctx.approval` before execution. `allowed-once` applies the requested mode only to that call; rejection, cancellation, unavailability, or missing approval context executes nothing and returns a distinct error. On a real denial, the model may retry the same command once in the same turn with the narrowest sufficient mode and justification; the approval prompt itself is the consent step. Escalation is never speculative, and a disabled or rejected approval is final. The [sandbox RFC](../../../docs/rfc/implemented/feature/2026-07-06-sandbox.md) owns the rationale. +Escalating bash calls resolve `ctx.approval` before execution. `allowed-once` applies the requested mode only to that call; rejection, cancellation, unavailability, or missing approval context executes nothing and returns a distinct error.

The [sandbox Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md) owns the rationale. ## Per-session mode switching -For sandboxing executors, each call resolves mode as one-shot escalation, then session override, then executor default. Non-sandboxing and agent-less calls carry no session override. Neither the prompt nor a switch notice announces the standing mode; denial results report the effective mode when the boundary matters.

a caller needing progress now must poll `bash_output` or send another message. -- **Tasks started outside an agent have no ownership fence** — their predictable ids are readable and killable by any caller; only agent-started tasks carry a session owner token. +- **The `bash` tool opts out of `timeout-policy` budgets** — it keeps the executor-owned `BASH_TIMEOUT` path, per [the tool-call timeout-policy Agent Note](../../../.agents/notes/implemented/architecture/2026-07-07-tool-call-timeout-policy.md). +- **Background processes have no executor timeout** — callers must use `task_kill`, or rely on owner/service disposal, when work no longer matters. diff --git a/packages/bash/tool-bash/package.json b/packages/bash/tool-bash/package.json index 4e23a928a7..816be1ef88 100644 --- a/packages/bash/tool-bash/package.json +++ b/packages/bash/tool-bash/package.json @@ -1,6 +1,6 @@ { "name": "@deepseek-ai/dsh-tool-bash", - "description": "Model-facing bash tools (bash, bash_output, bash_kill) over the DeepSeek Harness bash executor seam", + "description": "Model-facing bash tool with optional generic background-task and sandbox-escalation support", "version": "0.0.1", "private": true, "type": "module", @@ -25,24 +25,34 @@ "@deepseek-ai/dsh-agent": "^0.0.1", "@deepseek-ai/dsh-user-approval": "^0.0.1", "@deepseek-ai/dsh-bash": "^0.0.1", + "@deepseek-ai/dsh-home": "^0.0.1", "@deepseek-ai/dsh-llm": "^0.0.1", + "@deepseek-ai/dsh-session-persistence": "^0.0.1", "@deepseek-ai/dsh-sandbox": "^0.0.1", "@deepseek-ai/dsh-system-prompt": "^0.0.1", + "@deepseek-ai/dsh-tasks": "^0.0.1", "@deepseek-ai/dsh-tools": "^0.0.1", "cordis": "^4.0.0-rc.7" }, + "dependencies": { + "schemastery": "^3.18.0" + }, "devDependencies": { "@deepseek-ai/dsh-agent": "workspace:^", "@deepseek-ai/dsh-agent-loop": "workspace:^", + "@deepseek-ai/dsh-agent-loop-testkit": "workspace:^", "@deepseek-ai/dsh-user-approval": "workspace:^", "@deepseek-ai/dsh-bash": "workspace:^", "@deepseek-ai/dsh-bash-local": "workspace:^", - "@deepseek-ai/dsh-bash-sandbox": "workspace:^", + "@deepseek-ai/dsh-home": "workspace:^", "@deepseek-ai/dsh-llm": "workspace:^", "@deepseek-ai/dsh-sandbox": "workspace:^", - "@deepseek-ai/dsh-sandbox-local": "workspace:^", "@deepseek-ai/dsh-session": "workspace:^", + "@deepseek-ai/dsh-session-persistence": "workspace:^", + "@deepseek-ai/dsh-session-persistence-jsonl": "workspace:^", "@deepseek-ai/dsh-system-prompt": "workspace:^", + "@deepseek-ai/dsh-tasks": "workspace:^", + "@deepseek-ai/dsh-tool-tasks": "workspace:^", "@deepseek-ai/dsh-tools": "workspace:^", "cordis": "^4.0.0-rc.7" } diff --git a/packages/bash/tool-bash/src/background.ts b/packages/bash/tool-bash/src/background.ts new file mode 100644 index 0000000000..6ba67cdfde --- /dev/null +++ b/packages/bash/tool-bash/src/background.ts @@ -0,0 +1,27 @@ +/** + * Generic-task adaptation for background bash process handles. + * + * @module @deepseek-ai/dsh-tool-bash/background + */ + +import type { BashProcess } from '@deepseek-ai/dsh-bash' + +/** + * Map a settled background process onto the generic task-outcome vocabulary: + * `killed` stays `killed` (detail: the signal when one is known), everything + * else is `completed` with the exit code as detail.

the auto path logs a warning and proceeds. -- **The summarization call has no transcript-snapshot coverage** — `dsh-llm-replay` derives calls from `assistant/chunk` events, so this chunk-less direct `ctx.llm.stream()` call cannot replay (named deferred replay infrastructure in [the seam RFC](../../../docs/rfc/implemented/feature/2026-06-18-compaction-capability-seam.md)). +- **The summarization call has no transcript-snapshot coverage** — `dsh-llm-replay` derives calls from `assistant/chunk` events, so this chunk-less direct `ctx.llm.stream()` call cannot replay (named deferred replay infrastructure in [the seam Agent Note](../../../.agents/notes/implemented/feature/2026-06-18-compaction-capability-seam.md)). diff --git a/packages/compact/compact-basic/package.json b/packages/compact/compact-basic/package.json index 32852a060f..a0ee2b4036 100644 --- a/packages/compact/compact-basic/package.json +++ b/packages/compact/compact-basic/package.json @@ -1,6 +1,6 @@ { "name": "@deepseek-ai/dsh-compact-basic", - "description": "Basic compaction backend (chars-per-token estimation + token-budget retention + llm.generate() summarization) for the DeepSeek Harness", + "description": "Token-meter-driven compaction policy and LLM summarization backend for the DeepSeek Harness", "version": "0.0.1", "private": true, "type": "module", @@ -26,16 +26,23 @@ "@deepseek-ai/dsh-compact": "^0.0.1", "@deepseek-ai/dsh-llm": "^0.0.1", "@deepseek-ai/dsh-session": "^0.0.1", + "@deepseek-ai/dsh-token-meter": "^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-agent-loop-testkit": "workspace:^", "@deepseek-ai/dsh-compact": "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-token-meter": "workspace:^", "@deepseek-ai/dsh-tools": "workspace:^", "cordis": "^4.0.0-rc.7" } diff --git a/packages/compact/compact-basic/src/config.ts b/packages/compact/compact-basic/src/config.ts new file mode 100644 index 0000000000..1587fac272 --- /dev/null +++ b/packages/compact/compact-basic/src/config.ts @@ -0,0 +1,111 @@ +/** + * Runtime defaulting and policy validation for compact-basic. + * + * @module @deepseek-ai/dsh-compact-basic/config + */ + +import { deepFreeze } from '@deepseek-ai/dsh-llm' +import type { TokenMeterService } from '@deepseek-ai/dsh-token-meter' +import type { BasicCompactConfig, ResolvedConfig } from './types.ts' + +/** Default request-pressure fraction of the token meter's context window. */ +const DEFAULT_THRESHOLD_RATIO = 0.8 + +/** Default verbatim-tail fraction of the token meter's context window. */ +const DEFAULT_RETAIN_RATIO = 0.16 + +/** Complete public configuration key set. */ +const BASIC_COMPACT_CONFIG_KEYS: ReadonlySet<string> = new Set([ + 'thresholdRatio', + 'retainTokens', + 'summarizationProvider', + 'summarizationModel', + 'maxTokens', + 'compactionRetries', + 'maxOverflowRetries', + 'auto', +]) + +/** Reject stale or misspelled keys before defaults can hide them. */ +function validateConfigKeys(config: BasicCompactConfig): void { + for (const key of Object.keys(config)) { + if (!BASIC_COMPACT_CONFIG_KEYS.has(key)) { + throw new Error( + `BasicCompactConfig: unknown key "${key}" ` + + '(allowed: thresholdRatio, retainTokens, summarizationProvider, summarizationModel, ' + + 'maxTokens, compactionRetries, maxOverflowRetries, auto)', + ) + } + } +} + +/** + * Resolve defaults and validate the service-wide compaction policy. + * @param config - raw compact-basic configuration. + * @param tokenMeter - token meter supplying the context capacity. + * @returns a detached deeply immutable configuration. + */ +export function resolveConfig( + config: BasicCompactConfig = {}, + tokenMeter: TokenMeterService, +): ResolvedConfig { + validateConfigKeys(config) + const thresholdRatio = config.thresholdRatio ??

Returns the `CompactionResult`, or `null` if nothing needed compacting.

A pressure trigger may apply the backend's threshold and retained-tail policy; a confirmed overflow may force a useful balanced reduction.

Omission or `0` appends on every pre-step attempt whose signal is not already aborted. A positive value appends only when the session has no earlier time-context injection, wall time moved backward, or at least that many milliseconds have elapsed since the latest injection. -The duration starts at the latest user, assistant, tool-result, context, or steering message before the current `turn/start`. Every refresh in the turn retains that baseline, so the current prompt does not collapse the interval to approximately zero. The first turn reports that no earlier message exists. The durable clock source is session-event append time, not client send time. +## Timing semantics -The loop records the dynamic section in `request/header` / `request/header-delta`. Requests therefore remain reconstructable, carry one timing block, and retain no earlier readings in conversation history. +The plugin prepends an `agent/pre-step` listener. When an injection is due, it appends one `context/message` through `agent.inject()` before `step/start` and ordinary automatic compaction, with source `{ kind: 'plugin', plugin: 'time-context' }`. A suppressed attempt appends nothing. + +Positive-interval scheduling scans the raw durable session events for the latest `context/message` with that source, including a reading shadowed by compaction. The schedule therefore applies across turns and resumed processes without process-local cache state. It reduces append frequency and history growth but never removes an existing reading, and sessions schedule independently. + +Step 1 measures from the latest preceding model-visible message, including the prompt that opened the turn. Later steps measure from the preceding time-context event in the same turn. Both baselines use durable session-event timestamps; backward wall-clock movement clamps elapsed time to zero. A missing first-step baseline, or a later step with no earlier same-turn reading because interval suppression skipped it, reports `unavailable`. + +A time reading records a request-preparation attempt, not a committed step or transmitted request. Because the listener runs first, its append may remain when a later pre-step listener cancels or fails the attempt; the log is append-only and the plugin performs no rollback. + +The time reading stays in derived conversation history until a later compaction shadows it. Request headers contain no time-context state. Request reconstruction uses the complete durable surface prefix at each `step/start`, so transmitted requests need not map one-to-one to readings: a failed preparation can leave an extra reading, while interval suppression can let a request reuse existing history without adding one. ## Model Experience -### Temporal system prompt +### Preparation-time temporal context -**What the model sees**: Every request in an active turn includes the two lines below. `<timestamp>` is an ISO-shaped local timestamp with numeric offset and IANA zone; `<duration-or-unavailable>` is compact whole-second units or the first-turn fallback. +#### What the model sees -**Token effect**: Fixed two-line cost per request. A refresh replaces the request-header section; prior readings do not accumulate. +On each preparation attempt that injects, one source-tagged context message containing the two lines below. `<timestamp>` is an ISO-shaped local timestamp with numeric offset and IANA zone; durations use compact whole-second units. Positive intervals can leave an attempted step without a new reading. -#### Temporal context section +##### First step ```markdown -Current time: <timestamp> -Time since previous message: <duration-or-unavailable>. +Time sampled while preparing turn <turn>, step 1: <timestamp> +Elapsed since the preceding model-visible message: <duration-or-unavailable>. ``` +##### Later steps + +```markdown +Time sampled while preparing turn <turn>, step <step>: <timestamp> +Elapsed since the preceding step context: <duration-or-unavailable>. +``` + +#### Token effect + +Each injected two-line message accumulates until compaction shadows it.

The plugin freezes the initial user-global and project instruction chain into the request prefix, then discovers nested files and reports later changes or removals through durable context messages after successful filesystem tool calls. + +## Lifecycle + +The baseline is composed once per agent-loop instance on `agent/session-prefix`. It reads `$DSH_HOME/AGENTS.md` followed by one configured instruction candidate in each directory from the project root to `agent.session.header.cwd`. The prefix is placed before all derived history, recorded in `EpochHeader.messagePrefix`, and reused verbatim for that loop instance. Because the plugin prepends its contribution before delegating, a later-registered skills catalog appears after workspace instructions. + +The plugin also listens on `tools/post-execute` for successful first-party `read`, `write`, and `edit` calls. Each touch checks newly reached descendant scopes and every previously loaded scope. A new file is attached through the result's `additionalContexts`; a changed file or candidate switch appends a replacement; a missing final candidate appends a removal notice. Native calls and Code Mode sub-dispatches share this path: `run_code` defers each nested context until its outer result, so the loop still appends updates after tool-call/result adjacency is complete. This follows structured filesystem activity rather than shell `cd`, because each local bash call starts a fresh shell and parsing arbitrary shell syntax would be unreliable. + +Instruction reads use the optional `ctx.fs` provider. The plugin does not statically inject `fs`, so providerless product trees still boot and instruction loading becomes a no-op until a provider is present. It calls `ctx.fs.lstat` before resolving a candidate, rejecting a final-component symlink instead of following repository-owned links across the trust boundary. Once `lstat` identifies the winning regular-file candidate, a later resolve/stat failure makes that scope temporarily unavailable instead of falling through to a lower-priority name. Prefix cancellation and dynamic tool cancellation propagate through resolution, metadata probes, and streaming reads. A provider failure after a file was loaded is treated as temporarily unavailable, not as proof that the file was deleted. + +## Prompt Shape + +Baseline instructions are request-only user-role prefix messages framed with the familiar system-reminder pattern: + +```md +<system-reminder> +The following workspace instructions may be relevant to your work. Use them as guidance when applicable. More specific instructions take precedence over broader ones.

Use them as guidance when relevant; more specific instructions take precedence. They do not override system, developer, or direct user instructions. + +... +</system-reminder> +``` + +A same-file edit starts with `Updated instructions from: <path>` and says to use the new content instead of the previously loaded content. A candidate switch additionally names the old path. When no candidate remains, the message is `Instructions removed: <path>` followed by `The previously loaded instructions from this file no longer apply.` Literal `</system-reminder>` text inside an instruction file is escaped so file content cannot close the plugin-owned frame. + +The core `context/message` envelope is disabled for these messages because the plugin already owns the complete `<system-reminder>` framing. This is caller-selected with `envelope: 'raw'`; ordinary injected context still receives the canonical `<context source="...">` envelope. + +## State And Refresh + +Model-visible text contains no hidden state markers. Each dynamic context event instead carries JSON metadata with a versioned list of `{ action, scope, path, previousPath?, digest? }` changes. On every relevant tool touch, the plugin reconstructs loaded state from its visible session events and overlays a short in-memory pending window for context present on the immutable top-level `tools/result` but not yet appended by the loop. A matching durable `context/message` confirms the pending transition. If the owning `step/end` arrives before a matching context reaches the log, the plugin clears the pending transition and its version fast path so the next successful touch can load it again. Nested Code Mode results stage pending changes under the outer execution token for same-run duplicate suppression; the outer result rolls that state back and recommits only contexts that survived outer policy. + +An unchanged path and SHA-1 content digest is not injected again. A per-session, per-scope metadata cache stores only `{ path, version, digest }`: when the provider's opaque `FsVersion` and the effective visible state both match, reconciliation skips the content read; a changed version triggers a bounded read and SHA-1 confirmation before any model-visible update. Resume works because SHA-1 state is persisted in the session log, while an empty in-memory version cache merely causes one confirming read. Compaction re-arms a scope after its context event leaves the visible surface even when the cached version is unchanged. A removal is a tombstone, so a later candidate reappearance is loaded again. Only model-visible changes actually rendered within the byte budget enter metadata, pending state, and the version cache; an omitted change remains eligible for a later touch, while a same-digest version refresh updates metadata only. + +The frozen baseline itself is not rewritten mid-instance. Its initial path/digest map is retained as comparison state; the next successful filesystem touch appends any baseline replacement or removal. A resumed loop recomposes the current baseline and also reconciles still-visible dynamic scopes during prefix composition. There is no file watcher, so an on-disk change becomes visible at the next successful `read`, `write`, or `edit` touch, or when a resumed loop composes its prefix. + +## Configuration + +```ts +export interface Config { + dshHome?: string + projectRootMarkers?: string[] + maxBytes: number + maxSourceBytes?: number + instructionFileCandidates?: string[] +} +``` + +`maxBytes` is required so each deployment makes its prompt-budget choice explicitly. `maxSourceBytes` limits each source instruction file before rendering and defaults to 1 MiB. `projectRootMarkers` defaults to `['.git']`, and `instructionFileCandidates` defaults to `['AGENTS.md', 'CLAUDE.md']`. In each project directory, the first existing candidate wins; with defaults, `AGENTS.md` is native and `CLAUDE.md` is the compatibility fallback. Candidate entries must be same-directory file names, so empty entries, `.`/`..`, and entries containing `/` or `\` are ignored. + +The user-global file is always `$DSH_HOME/AGENTS.md`; the candidate list only controls project scopes. `$DSH_HOME` defaults to `~/.dsh`, and configured `~`, `~/...`, and Windows-style `~\...` prefixes are expanded against the operating-system home directory. A non-positive or non-finite render budget disables both baseline and dynamic loading; configured `maxSourceBytes` must be a positive integer. + +## Budgeting And Bounded Reads + +Rendering preserves the most specific instruction files first. It drops whole broader files before truncating the most-specific file and emits a visible `Workspace instruction budget ...` notice naming omitted and truncated paths. The rendered bytes never exceed `maxBytes`. + +Instruction content is read through `streamText()` under `maxSourceBytes`, even when provider metadata omits size or a file grows after its metadata probe. An oversized file is ignored without falling through to a lower-priority same-directory candidate; during dynamic reconciliation it is temporarily unavailable rather than removed. The plugin keeps no process-wide cache and never caches instruction prose. Its session-local scope cache uses provider versions only as a fast invalidation signal; after invalidation, SHA-1 over the bounded read remains the cross-provider content identity stored in structured session metadata. + +## Model Experience + +### Baseline session prefix + +#### What the model sees + +At the first request of each loop instance, the model receives one user-role prefix message containing the bounded user-global and project instruction chain in broad-to-specific order. + +##### Baseline instruction template + +```markdown +<system-reminder> +The following workspace instructions may be relevant to your work.

Every plugin (UI, hooks, orchestrators) programs against the `Agent` handle defined here — it has zero loop dependency, so the loop is swappable. ## Service: `AgentRegistry` (ctx key: `agents`) -Tracks live agents so UI, hook, and orchestrator plugins can find them without importing the concrete loop package. +Tracks live agents and carries the initiating Agent through asynchronous driver work without importing the concrete loop package. ### Public API -`Agent.ctx` owns registrations visible only to that agent. `agentEvents()` couples event subjects to their scope carrier, and `assembleContextFor()` couples the agent and prompt scope. Creation and resume may compose this context through `setup`; the agent remains unpublished and must not be driven until creation resolves. +The scoped-registration surface: `Agent.ctx` is the agent's scope context (`dsh-scope`, key = the agent) — register tools/sections/variables/listeners through it for that agent alone, all unwound on disposal. `agentEvents(ctx, agent)` is the fused dispatcher for ordinary agent-subject operations (carrier + injected subject in one move); its notification mode invokes every listener and contains both synchronous throws and returned-promise rejections. The registry lifecycle pair reuses one stable routing carrier. `assembleContextFor(agent)` builds the per-agent assembly context (`agent` + `scope` together). `CreateAgentOptions.setup(agentCtx)` and `ResumeAgentOptions.setup(agentCtx)` compose a fresh or resumed agent's scoped world while both objects remain unpublished. Setup is trusted, composition-only same-process code: drive the agent only after creation resolves. - `ctx.agents.register(agent: Agent): () => void` — record an **already-constructed** agent. Disposed with the calling fiber. -- Advanced factory lifecycle: `enter(agent)` publishes without announcing and returns an entry-bound detach; `announce(agent)` emits creation once. Detach during creation dispatch is deferred. Ordinary plugins use `register()`. -- `ctx.agents.get(id: AgentId): Agent | undefined` +- Advanced ordered lifecycle: `enter(agent, owner): () => void` enforces `agent.id === agent.session.id`, performs the authoritative ID collision check, and inserts without announcing; `owner` explicitly records the live creator-agent relation (or `undefined` for a root), independently of durable session lineage. `announce(agent)` emits `agent/created` exactly once. A detach requested synchronously by a creation listener is deferred until that dispatch unwinds, and every detach checks the captured entry object, so a stale capability cannot delete a later same-ID replacement. The async factory uses this split; ordinary plugins use `register()`. +- `ctx.agents.get(id: SessionId): Agent | undefined` +- `ctx.agents.isOwnedBy(id: SessionId, owner: Agent): boolean` — whether the exact live entry was created through that parent agent's scoped context; runtime ownership is independent of durable session lineage. - `ctx.agents.list(): Agent[]` +- `ctx.agents.roots(): Agent[]` — live agents created without an owning agent context; a resumed lineage-bearing session can still be a runtime root. + +#### Initiating Agent scope + +`AgentLoop` runs each concrete driver's complete lifetime inside an initiator boundary. Concurrent drivers remain isolated: a child driver's continuations carry the child, while the parent continuation regains the parent as soon as `withInitiator()` returns; drain tracking continues until the child driver's Promise settles. Creation, persistence load, and unpublished setup remain outside the child's boundary, so setup initiated by a parent inherits the parent while `agentCtx.agent` identifies the child explicitly. + +- `ctx.agents.currentInitiator(): Agent | undefined` — read the inherited initiator without requiring one. +- `ctx.agents.requireInitiator(): Agent` — read it or throw `no initiating agent is active`. +- `ctx.agents.withInitiator(agent, operation)` — run with one exact Agent and preserve the operation's exact synchronous value or Promise. +- `ctx.agents.withoutInitiator(operation)` — hide an inherited initiator for unrelated process-local work. + +The scope carries the `Agent` itself and is process-local. Ambient presence is neither liveness proof nor authorization; explicit Agent fields remain authoritative at service, worker, process, persistence, and wire boundaries. Teardown rejects new boundaries, lets injected dependents and returned-Promise boundaries drain, then disables the underlying `AsyncLocalStorage`; unreturned work remains owned by the subsystem that detached it. If a boundary's inherited async chain starts an owning Cordis fiber's unload, that nested boundary chain is released from the drain so the unload cannot wait on itself; its continuations observe the disposed service after teardown. The [initiator-scope decision](../../../.agents/notes/implemented/architecture/2026-07-15-agent-initiator-scope.md) owns the detailed boundary and teardown contract. #### Factory seam (creation) -The loop plugin registers `AgentFactory`, keeping consumers independent of its concrete package. Each call is traced through the caller's context so the caller owns the resulting transaction and handle. +Agent *creation* is provided by the plugin implementing `AgentFactory` (`dsh-agent-loop`), registered via `setFactory`. This keeps creation on the `dsh-agent` interface so consumers (UI, the ACP bridge) program against `ctx.agents` without depending on the concrete loop package. The registry canonicalizes an already traced Service to its concrete target and re-traces each call through the caller's context; this avoids nested Cordis shadows while passing an explicit caller-bound `ownerCtx` to plain factories. - `ctx.agents.setFactory(factory: AgentFactory): () => void` — register the creation factory (the loop calls this on construction). Throws on a second factory; the slot clears on dispose. -- `ctx.agents.create(options)` creates and composes an unpublished session and agent, then atomically enters the registries and starts the loop. A creation-only signal cancels before publication; same-ID contenders arbitrate at entry and losers roll back. -- `ctx.agents.resume(options)` loads a persisted session and follows the same composition and publication boundary.

Concurrent same-ID creation is unsupported: more than one operation may prepare, but only one can enter; every loser rolls its private scope/session/driver back. An optional creation-only `signal` cancels unpublished setup and is detached before the handle is returned; later cancellation uses `handle.dispose()` or `agent.cancel()`. Publication is rollback-covered and every delivered creation edge is paired during rollback. Rejects if no factory is registered. +- `ctx.agents.resume(options: ResumeAgentOptions): Promise<AgentHandle>` — load a persisted session ([session persistence](../../../.agents/notes/implemented/architecture/2026-06-14-session-persistence.md)), mint a fresh unpublished agent scope, await optional setup, and use the same final-entry publication sequence. Its optional `signal` is likewise creation-only. Rejects if no factory is registered or session persistence is unconfigured. -`AgentHandle = { agent, dispose }` is the consumer teardown capability; registry observers receive only the bare agent. Disposal stops and drains the loop and idle-injection flushes before unregistering the agent, detaching its session, and unwinding its scope. Caller and factory unload share that memoized boundary. +`AgentHandle = { agent: Agent; dispose(): Promise<void> }`. The disposer is a **consumer capability** — no observer holding the bare registry entry can tear the agent down. The caller fiber and the registered factory provider are structural co-owners: caller unload enforces structured ownership, while factory unload must stop old instances because their scoped dependency surface belongs to that provider. `dispose()` from any owner reaches one memoized quiescence boundary: it stops the loop, `await`s its exit plus every outstanding idle-injection flush (not just the `disposed` status flip), unregisters the agent, removes its session from the store, and finally unwinds its scoped world. This order captures every agent-started `session/flush` before the session is detached and keeps scoped listeners alive through those checkpoints. `ctx.agents.get(id)` still returns a bare `Agent`; the ACP bridge and in-process subagent backends hold consumer handles, while config-created agents are already owned by the loop fiber. ### Live events `dsh-agent` declares the live `agent/*` coordination vocabulary so plugins do not depend on the concrete loop. Exact signatures, dispatch modes, scope-filtering rules, and payload contracts live in the generated [Cordis event catalog](../../../docs/cordis-catalog/events.md); the [architecture turn flow](../../../docs/architecture.md#turn-flow) shows their order relative to durable session events. -`agent/created` runs after setup and both registry entries; the following `agent/session-start` is the first supported startup injection point. `agent/disposed` means the exact entry left the registry. The loop quiesces its driver first; directly registered custom agents own any stronger ordering. +The lifecycle edges have two important local caveats. `agent/created` runs after scoped setup and after both session and agent registry entries exist. Setup is trusted composition-only code; the immediately following non-vetoing `agent/session-start` notification is the first supported startup injection point. `agent/disposed` always means the exact agent has left the registry. AgentLoop emits it after its driver is quiescent, while ordered teardown may still be detaching the session and unwinding the scope; custom agents registered directly own any stronger driver-ordering contract themselves. -Most interception points are cooperative waterfalls returning seam-specific decisions. `agent/pre-step` is a serial surface-mutation checkpoint, while `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.

Deterministic — lexicographic tool order, byte-identical text for an unchanged tool set (prefix-cache-friendly). The codegen (`jsonSchemaToTs`, exported) is total: constructs outside the `defineTool` subset degrade to `unknown`, never throw. +- **The dispatch bridge** (`run_code`'s execute): every binding call is JSON-normalized before dispatch (a value that does not survive — `BigInt`, circulars — rejects that one call, so the dispatched form and logged form are the same JSON value by construction), serialized through a per-run queue (even `Promise.all` executes underlying calls one at a time in submission order), given the outer execution's opaque token as `parent`, and run through the complete pre-execute → guards → execute → post-execute → result pipeline. A denial reaches the program as a binding rejection, and each sub-call is logged as a `tool/code-dispatch` session event with deterministic id `<parent>:code:<n>`; `deriveMessages()` does not surface that event. Token correlation lets commit-style observers defer an inner success until the final `run_code` result without exposing the live outer execution; ordinary tool side effects are not rolled back. Every sub-call `additionalContexts` entry is deferred through the outer `ToolRunContext` in dispatch order; the loop appends those contexts only after the parent `run_code` result, preserving adjacency and retaining each source/envelope/meta even when the program later fails. +- **Settlement discipline**: the bridge owns a run-scoped abort that follows the outer signal in and fires when the run settles for any reason, so a budget expiry aborts an in-flight sub-tool instead of orphaning it; the bridge then drains its queue BEFORE returning, so every `tool/code-dispatch` lands inside the open turn. A failed run throws `CodeRunFailedError` (`code: 'CODE_RUN_FAILED'`, message = the failure kind + captured logs), which the pipeline converts to a structured `isError` the model self-corrects from. + +### Parallel execution + +The agent loop groups consecutive `parallel` calls into a bounded rolling pool and treats each `exclusive` call as an ordering barrier. Only dispatch/body overlaps; policy, durable results, and context retain model order. Code Mode bindings remain serial.

Set `skills.enabled: false` to omit both the local provider and model-facing skill tool, and set `toolTasks: false` to retain the task service for foreground producers without exposing `task_output` / `task_list` / `task_kill`. It resolves `dshHome` once through [`@deepseek-ai/dsh-home`](../../util/home/README.md) and forwards that absolute value to tool-bash's managed environment and enabled local skill discovery. An absent top-level `dshHome` adopts `skills.local.dshHome`; supplying both with different resolved paths fails loudly. `toolBash.enableRunInBackground` controls only the bash producer; independently loaded producers keep their own config. Workspace instructions register before the skill catalog so their session-prefix message renders first.

The root command supplies the Node flag. + +### Output formats + +- `text` writes the last assistant message containing text, followed by one newline. +- `json` writes one DSH-native result record: `{ type: "result", success, sessionId, turn, result, reason, usage? }`. `usage` sums every model step in the task turn. +- `stream-json` writes each canonical event from the top-level session's task turn as `{ type: "session_event", sessionId, event }`, then the same result record. Child-agent activity appears only through the parent tool events and results. + +Only `reason.kind === "completed"` exits successfully.

A task can therefore mutate the launch workspace, run commands, spawn child agents, and consume provider tokens.

Through `dsh-agent-spine-demo`, the top-level agent also receives configured workspace instructions and persona, the skill catalog, visible tool schemas, and retained tool results needed for later steps in the same turn. + +#### Token effect + +The task, prompt sections, tool schemas, assistant output, and tool results consume tokens on each model step. JSON event streaming and final rendering add no model tokens; delegated child work has its own model usage and is not included in the parent result's `usage` total. + +#### KV Cache effect + +Tool-round history is append-only while the one-shot agent's prompt, schemas, model route, and session prefix remain fixed. Changing that composition establishes a different request prefix; JSON output mode has no cache effect. + +## Known Limitations and Deferred Work + +- **One fresh top-level session per process** — its workspace cwd is the launch directory; there is no resume, second prompt, stdin context, or concurrent top-level session in this app. +- **No interactive question or approval provider** — tools that require a human answer cannot complete unless a different leaf composes a non-interactive provider with explicit policy. +- **Streaming is top-level-session-only** — child sessions are not flattened into the stream, and aggregate usage covers only model steps recorded on the parent task turn. diff --git a/packages/examples/cli-demo/package.json b/packages/examples/cli-demo/package.json new file mode 100644 index 0000000000..7b035e2524 --- /dev/null +++ b/packages/examples/cli-demo/package.json @@ -0,0 +1,61 @@ +{ + "name": "@deepseek-ai/dsh-cli-demo", + "description": "Headless one-shot agent app with text and DSH-native JSON output", + "version": "0.0.1", + "private": true, + "type": "module", + "main": "lib/index.js", + "types": "lib/types/index.d.ts", + "bin": { + "dsh-cli-demo": "lib/bin.js" + }, + "exports": { + ".": { + "types": "./lib/types/index.d.ts", + "default": "./lib/index.js" + }, + "./bin": { + "types": "./lib/types/bin.d.ts", + "default": "./lib/bin.js" + }, + "./src/*": "./src/*", + "./package.json": "./package.json" + }, + "files": [ + "lib/index.js", + "lib/bin.js", + "lib/types/**/*.d.ts", + "lib/types/**/*.d.ts.map", + "src" + ], + "license": "BSD-3-Clause", + "peerDependencies": { + "@cordisjs/plugin-include": "^1.0.4", + "@cordisjs/plugin-loader": "^1.0.0-rc.5", + "@deepseek-ai/dsh-agent": "^0.0.1", + "@deepseek-ai/dsh-agent-spine-demo": "^0.0.1", + "@deepseek-ai/dsh-app-boot": "^0.0.1", + "@deepseek-ai/dsh-llm": "^0.0.1", + "@deepseek-ai/dsh-session": "^0.0.1", + "@deepseek-ai/dsh-session-persistence-jsonl": "^0.0.1", + "@deepseek-ai/dsh-tools": "^0.0.1", + "@deepseek-ai/dsh-workspace-context": "^0.0.1", + "cordis": "^4.0.0-rc.7", + "schemastery": "^3.17.0" + }, + "devDependencies": { + "@cordisjs/plugin-include": "workspace:^", + "@cordisjs/plugin-loader": "workspace:^", + "@deepseek-ai/dsh-agent": "workspace:^", + "@deepseek-ai/dsh-agent-spine-demo": "workspace:^", + "@deepseek-ai/dsh-app-boot": "workspace:^", + "@deepseek-ai/dsh-llm": "workspace:^", + "@deepseek-ai/dsh-session": "workspace:^", + "@deepseek-ai/dsh-session-persistence-jsonl": "workspace:^", + "@deepseek-ai/dsh-system-prompt": "workspace:^", + "@deepseek-ai/dsh-tools": "workspace:^", + "@deepseek-ai/dsh-workspace-context": "workspace:^", + "cordis": "^4.0.0-rc.7", + "schemastery": "^3.17.0" + } +} diff --git a/packages/examples/cli-demo/src/bin.ts b/packages/examples/cli-demo/src/bin.ts new file mode 100644 index 0000000000..5b6638ef72 --- /dev/null +++ b/packages/examples/cli-demo/src/bin.ts @@ -0,0 +1,34 @@ +#!/usr/bin/env node +/** + * Process wrapper for `dsh-cli-demo`; covered parsing and task execution live in + * `cli.ts` while this entry owns Unix signal-to-exit-code mapping. + * @module @deepseek-ai/dsh-cli-demo/bin + */ + +import { installFailLoud } from '@deepseek-ai/dsh-app-boot' +import { executeCli } from './cli.ts' + +const NAME = 'dsh-cli-demo' + +/* v8 ignore start -- thin self-executing process glue; built-bin tests exercise + real argv, signals, Loader boot, output, and exit codes */ +const abort = new AbortController() +let signalExitCode: number | undefined +const interrupt = (signal: 'SIGINT' | 'SIGTERM', code: number): void => { + signalExitCode ??= code + if (!abort.signal.aborted) abort.abort(`received ${signal}`) +} +const onSigint = (): void => { interrupt('SIGINT', 130) } +const onSigterm = (): void => { interrupt('SIGTERM', 143) } +const uninstallFailLoud = installFailLoud(NAME) +process.on('SIGINT', onSigint) +process.on('SIGTERM', onSigterm) +try { + const code = await executeCli(process.argv.slice(2), { signal: abort.signal }) + process.exitCode = signalExitCode ?? code +} finally { + process.off('SIGINT', onSigint) + process.off('SIGTERM', onSigterm) + uninstallFailLoud() +} +/* v8 ignore stop */ diff --git a/packages/examples/cli-demo/src/cli.ts b/packages/examples/cli-demo/src/cli.ts new file mode 100644 index 0000000000..68c9598e6c --- /dev/null +++ b/packages/examples/cli-demo/src/cli.ts @@ -0,0 +1,447 @@ +/** + * Command parser and one-turn driver for `dsh-cli-demo`.

A composition change or compaction may invalidate reuse from its first changed token; terminal rendering has no cache effect. + +### Human-answer result + +#### What the model sees + +Through `dsh-tool-ask-user`, successful terminal answers use that package's exact compact JSON shape.

The `targetKey` is the file's `realpath`, so two input paths reaching the same file through symlinks share one identity, and writes/edits land on the link target (preserving the link). A not-yet-existing path uses the realpathed parent directory plus basename when the parent exists; only an unresolvable parent falls back to the absolute path. `displayPath` is the absolute (un-resolved) path. +- **`stat` / `lstat`** — return target metadata or `undefined` when absent. `stat` reports `FsInfo` for an already resolved target (`version` = an opaque token derived from bigint `dev:ino:size:mtimeNs:ctimeNs`, `type` of `file`/`directory`/`other`, byte `size`); path-shaped `lstat` reports `FsPathInfo` without following the final symlink and can therefore return `symlink`. 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`. Broken/disappeared children are returned as `other` without metadata, but permission/IO failures while resolving a child fail the whole listing with a structured `FsError`. - **`writeText`** — atomic: writes to a temp file opened exclusively (`wx`, `0o600`) inside a randomly-named private staging dir (`0o700`) next to the target, fsyncs, then renames over the target. An existing file's mode is preserved, while new files default to `0o600`. The `expected` guard is OPTIONAL: omitting it unconditionally creates-or-overwrites; `createIfAbsent` creates a missing target and rejects an existing one (`FS_NOT_OBSERVED`); `replaceIfVersion` replaces only at the observed version (a missing target or mismatch is `FS_STALE_VERSION`). @@ -25,9 +25,13 @@ The package-root SDK surface is the default/named `LocalFileSystem` class plus ` Indirectly, through [`dsh-tool-fs`](../tool-fs/README.md), which renders this provider's line-windowed UTF-8 content, mutation acknowledgements, and exact provider messages in capped retained results while versions, atomic-write mechanics, and directory metadata remain internal. +#### KV Cache effect + +No direct invalidation; the named consumer owns any request-prefix changes. + ## Known Limitations and Deferred Work -- **`config.cwd` is not a sandbox** — it is a resolution default, not containment: absolute paths and `..` escape it.

Returns one path per line, modification-time ordered. | +| `grep` | `pattern`, `path?`, `include?` | Line-oriented `rg --json` parse (no colon-splitting ambiguity). `pattern` is a ripgrep regex; `path` is an optional **file or directory** target; `include` is ONE positive glob filter — a comma-separated list or a negated (`!…`) value is rejected up front (brace alternation like `*.{ts,tsx}` is fine). Returns matches grouped by file as `Line N: <preview>`. | + +Routine budgets stay out of the model-facing schema (no `head_limit`/`offset`/`case_insensitive`/output modes): a model that needs surrounding context reads the matched file with `read`; one that needs later results follows the returned spill locator's retrieval hint. + +## Two budgets, two artifacts + +Raw `rg` stdout is an internal transport detail. Each search requests `stdoutMaxBytes: rawOutputMaxBytes` from the bash seam and parses only complete retained stdout; if the executor still returns `stdout.truncated`, the search fails with `SEARCH_RAW_OUTPUT_OVERFLOW` and tells the model to narrow the query. The model-facing recovery artifact is different: when a search yields more logical results than the inline cap, the tool saves the COMPLETE formatted result through `ctx.spillStore.saveText()` (suggested names `glob-results.txt` / `grep-results.txt`, owner = the calling session, source = the tool execution identity) and appends a footer naming the returned locator and retrieval hint. This is the first tool-owned spill call in the codebase — deliberate, because retention here is item-level: the generic `@deepseek-ai/dsh-spill-policy` only sees the final text on `tools/post-execute`, by which point a capped search has already omitted later paths/matches. A missing spill backend, a call with no session owner, or a `saveText()` failure keeps the inline page and reports that the complete result could not be saved — never an `isError`. + +## Errors + +Search failures carry the package-owned `SearchError` (a `HarnessError` subclass), surfaced as `{ name, code }` on `isError` results: `SEARCH_INVALID_PATTERN` (ripgrep rejected the regex/glob), `SEARCH_FAILED` (runtime `rg` disappearance after registration, inaccessible target, signal kill, malformed `--json` output), `SEARCH_RAW_OUTPUT_OVERFLOW` (raw output over `rawOutputMaxBytes`, or still truncated after the requested stdout capture budget), and `SEARCH_ABORTED` (tool timeout, caller cancellation, or the bash executor's own timeout). ripgrep exit semantics are tool-owned: exit 0 is success with results, exit 1 is a successful empty search (`No files found` / `No matches found`), and only other exits are failures. Model argument mistakes (blank pattern, a list-valued `include`) stay ordinary tool argument errors. + +## Model Experience + +### System prompt + +#### What the model sees + +After the load-time `rg` probe succeeds, every request in this plugin's registration scope contains the independently registered glob and grep guidance below.

Remote or virtual filesystems need a co-located executor or another search consumer. +- **The schemas expose one bounded page** — offset pagination, case-mode switches, alternate output modes, and provider-backed discovery remain outside this package; capped complete output requires a spill backend. diff --git a/packages/fs/tool-fs-search/package.json b/packages/fs/tool-fs-search/package.json new file mode 100644 index 0000000000..002d54569a --- /dev/null +++ b/packages/fs/tool-fs-search/package.json @@ -0,0 +1,49 @@ +{ + "name": "@deepseek-ai/dsh-tool-fs-search", + "description": "Model-facing filesystem discovery tools (glob, grep) backed by the DeepSeek Harness bash seam (ctx.bash)", + "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" + }, + "./src/*": "./src/*", + "./package.json": "./package.json" + }, + "files": [ + "lib/index.js", + "lib/types/**/*.d.ts", + "lib/types/**/*.d.ts.map", + "src" + ], + "license": "BSD-3-Clause", + "dependencies": { + "schemastery": "^3.18.0" + }, + "peerDependencies": { + "@deepseek-ai/dsh-bash": "^0.0.1", + "@deepseek-ai/dsh-llm": "^0.0.1", + "@deepseek-ai/dsh-retention": "^0.0.1", + "@deepseek-ai/dsh-session": "^0.0.1", + "@deepseek-ai/dsh-spill": "^0.0.1", + "@deepseek-ai/dsh-system-prompt": "^0.0.1", + "@deepseek-ai/dsh-tools": "^0.0.1", + "cordis": "^4.0.0-rc.6" + }, + "devDependencies": { + "@deepseek-ai/dsh-agent": "workspace:^", + "@deepseek-ai/dsh-bash": "workspace:^", + "@deepseek-ai/dsh-bash-local": "workspace:^", + "@deepseek-ai/dsh-llm": "workspace:^", + "@deepseek-ai/dsh-retention": "workspace:^", + "@deepseek-ai/dsh-session": "workspace:^", + "@deepseek-ai/dsh-spill": "workspace:^", + "@deepseek-ai/dsh-system-prompt": "workspace:^", + "@deepseek-ai/dsh-tools": "workspace:^", + "cordis": "^4.0.0-rc.6" + } +} diff --git a/packages/fs/tool-fs-search/src/glob.ts b/packages/fs/tool-fs-search/src/glob.ts new file mode 100644 index 0000000000..a3e803fb50 --- /dev/null +++ b/packages/fs/tool-fs-search/src/glob.ts @@ -0,0 +1,179 @@ +/** + * The model-facing `glob` tool: discover files whose paths match a glob + * pattern, sorted by modification time.

Denial, feedback, and forced-continuation context append after the reusable prefix without rewriting it. ## Known Limitations and Deferred Work - **Unsupported hook events (23 of Claude Code's current 30):** `Setup`, `InstructionsLoaded`, `UserPromptExpansion`, `MessageDisplay`, `PermissionRequest`, `PostToolUseFailure`, `PostToolBatch`, `PermissionDenied`, `Notification`, `TaskCreated`, `TaskCompleted`, `StopFailure`, `TeammateIdle`, `ConfigChange`, `CwdChanged`, `FileChanged`, `WorktreeCreate`, `WorktreeRemove`, `PreCompact`, `PostCompact`, `SessionEnd`, `Elicitation`, and `ElicitationResult`. Config for these events is parsed but never dispatched. The comparison baseline is Claude Code's [official hook-event reference](https://code.claude.com/docs/en/hooks#hook-events). - **`SessionStart` is partial:** JSON `additionalContext` is consumed, but plain stdout context, `initialUserMessage`, `sessionTitle`, `watchPaths`, `reloadSkills`, and `CLAUDE_ENV_FILE` are unsupported. The hook runs detached, so context can miss the first request (`TODO(session-start-gating)`), and the payload omits current optional fields such as `model`, `agent_type`, and `session_title`. - **`UserPromptSubmit` is partial:** blocking and JSON `additionalContext` work, but plain stdout context, `sessionTitle`, and `suppressOriginalPrompt` are unsupported. Unless overridden, the bridge also uses its 600-second default instead of Claude Code's event-specific 30-second command timeout. -- **`PreToolUse` is partial:** `deny` and `ask` decisions work; `allow` does not pre-approve, `defer` is unsupported, `additionalContext` is ignored, and `updatedInput` is logged + warned but not honored ([the pre-tool-input-rewrite RFC](../../../docs/rfc/proposed/feature/2026-06-30-pre-tool-input-rewrite.md)). +- **`PreToolUse` is partial:** `deny` and `ask` decisions work; `allow` does not pre-approve, `defer` is unsupported, `additionalContext` is ignored, and `updatedInput` is logged + warned but not honored ([the pre-tool-input-rewrite Agent Note](../../../.agents/notes/proposed/feature/2026-06-30-pre-tool-input-rewrite.md)). - **`PostToolUse` is partial:** blocking feedback and JSON `additionalContext` work, but `updatedToolOutput` and `updatedMCPToolOutput` are unsupported and `tool_response` is flattened to text. - **`SubagentStart` and `SubagentStop` are partial:** both report a constant `agent_type` of `general-purpose` and use the child session id where Claude Code reports the parent session. Start context is best-effort and can only reach a live in-process child, while stop is observe-only and cannot block the subagent or feed it context. Start omits `transcript_path`; stop also omits `agent_transcript_path`, `last_assistant_message`, `background_tasks`, and `session_crons` and always reports `stop_hook_active: false`. - **`Stop` is partial:** blocking forces another model turn, but `stop_hook_active` is always `false`, `last_assistant_message`, `background_tasks`, and `session_crons` are omitted, and the consecutive-block cap is not implemented (`TODO(stop-loop-guard)`). An unconditionally blocking hook therefore force-continues every step unless it self-limits. diff --git a/packages/hooks/hooks-claude/package.json b/packages/hooks/hooks-claude/package.json index 21f08965d8..c6870a6471 100644 --- a/packages/hooks/hooks-claude/package.json +++ b/packages/hooks/hooks-claude/package.json @@ -29,6 +29,7 @@ "@deepseek-ai/dsh-hook-protocol": "^0.0.1", "@deepseek-ai/dsh-llm": "^0.0.1", "@deepseek-ai/dsh-session": "^0.0.1", + "@deepseek-ai/dsh-session-persistence": "^0.0.1", "@deepseek-ai/dsh-subagent": "^0.0.1", "@deepseek-ai/dsh-tools": "^0.0.1", "cordis": "^4.0.0-rc.7" @@ -36,13 +37,15 @@ "devDependencies": { "@deepseek-ai/dsh-agent": "workspace:^", "@deepseek-ai/dsh-agent-loop": "workspace:^", + "@deepseek-ai/dsh-agent-loop-testkit": "workspace:^", "@deepseek-ai/dsh-bash": "workspace:^", "@deepseek-ai/dsh-bash-local": "workspace:^", "@deepseek-ai/dsh-hook-protocol": "workspace:^", "@deepseek-ai/dsh-llm": "workspace:^", "@deepseek-ai/dsh-session": "workspace:^", + "@deepseek-ai/dsh-session-persistence": "workspace:^", + "@deepseek-ai/dsh-session-persistence-jsonl": "workspace:^", "@deepseek-ai/dsh-subagent": "workspace:^", - "@deepseek-ai/dsh-system-prompt": "workspace:^", "@deepseek-ai/dsh-tools": "workspace:^", "cordis": "^4.0.0-rc.7" } diff --git a/packages/hooks/hooks-claude/src/index.ts b/packages/hooks/hooks-claude/src/index.ts index 08a2d26c9d..03ac21fea6 100644 --- a/packages/hooks/hooks-claude/src/index.ts +++ b/packages/hooks/hooks-claude/src/index.ts @@ -5,7 +5,7 @@ * mapping; shared execution and parsing live in `dsh-hook-protocol`. * `updatedInput` is logged and warned but not honored.

One plugin instance owns an explicit list of provider profiles; every request selects a profile with `GenerateOptions.provider` and resolves `GenerateOptions.model` dynamically from pi-ai's installed catalog. -## Why a second adapter exists - -`@deepseek-ai/dsh-llm-deepseek` already talks to the same endpoint. This package is its **design-verification twin**: same models, same wire protocol, completely different internals — a unified LLM library with its own event vocabulary versus hand-rolled fetch/SSE. Anything the harness `StreamChunk` protocol cannot express for BOTH implementations is a core-vocabulary bug. The differences it exercised on purpose: - -- pi-ai hands tool-call `arguments` around as **parsed objects**; the harness keeps raw JSON strings. The adapter patches replay payloads back to the original raw strings before sending them, and re-stringifies parsed output tool calls at `block-end`. -- pi-ai reports failures as **in-stream error events** (it never throws mid-stream); these map to `finish {kind:'error'|'aborted'}` chunks — the protocol's other sanctioned error path besides throwing (which llm-deepseek uses). -- pi-ai folds reasoning tokens into `usage.output`; there is no separate reasoning count to map. -- pi-ai's options omit some DeepSeek/OpenAI-compatible details; the adapter uses its `onPayload` hook to preserve the harness contract (`stop`, scrubbing pi-ai's own per-tool `strict` default — the hand-rolled twin sends no such field — omitted reasoning effort, raw replayed tool arguments). +The package root exposes the Cordis plugin contract and `PiAiAdapter`; profile resolution, model construction, replay conversion, and stream conversion remain package-internal. ## Config -Same shape as llm-deepseek (one-line swap in cordis.yml), with pi-ai's thinking-level vocabulary: +Configure credentials and deployment-specific transport settings per provider. Omitting `apiKey` delegates authentication to pi-ai's provider-native ambient discovery. `baseURL` overrides only the endpoint of the selected catalog model, preserving its API family and compatibility metadata, so private proxies such as `https://proxy.example.com:8443` remain supported. ```yaml - id: llm name: '@deepseek-ai/dsh-llm-pi-ai' config: - apiKey: !!js process.env.DEEPSEEK_API_KEY - baseURL: !!js process.env.DEEPSEEK_BASE_URL - models: [deepseek-v4-flash, deepseek-v4-pro] - reasoning: high # off | high | xhigh (xhigh → wire 'max') + providers: + - provider: openai + apiKey: !!js process.env.OPENAI_API_KEY + baseURL: https://proxy.example.com:8443 + reasoning: high + - provider: anthropic + apiKey: !!js process.env.ANTHROPIC_API_KEY + maxRetries: 2 + - provider: openrouter + apiKey: !!js process.env.OPENROUTER_API_KEY + headers: + X-Deployment: production ``` +Each provider name must exist in pi-ai's installed catalog and may appear only once in this plugin instance. Registration with `ctx.llm` is atomic: a collision with any provider route already owned by another adapter fails plugin loading without registering the remaining routes. Model ids are not lifecycle config; an unknown model fails before any provider request with `LlmError('UNKNOWN_MODEL')`. + +The adapter exposes each configured provider's installed pi-ai models through `ctx.llm.listModels(provider)`. This is provider-neutral selector metadata derived from `getModels(provider)`; request-time resolution still performs the authoritative catalog lookup, so discovery does not create a second model registry. + +Supported profile fields are `provider`, `apiKey`, `baseURL`, `headers`, `reasoning`, `thinkingBudgets`, `cacheRetention`, `transport`, `timeoutMs`, `websocketConnectTimeoutMs`, `maxRetries`, and `maxRetryDelayMs`. They map to pi-ai's common stream options. Harness app attribution wins a conflicting configured header name. + +## Provider/model routing and replay + +The selected pi-ai catalog descriptor supplies the protocol implementation. This includes native API differences such as OpenAI models whose descriptor uses the Responses API rather than Chat Completions; the harness adapter does not hardcode endpoint selection by model name. + +Successful assistant responses store a versioned, lossless-JSON replay state beside their durable provider/model provenance. At request time, `LlmService` passes replay state only when the historical provider route and target provider route are currently owned by this same `PiAiAdapter` instance. The adapter validates the state and restores pi-ai response ids and provider signatures even when the target provider or model changes; pi-ai then decides which metadata its target API can reuse. History without replay state is translated as foreign provider-neutral content and never impersonates a native pi-ai response. + +If a listener rewrites assembled assistant content, the loop drops replay state before logging the message because its provider metadata no longer describes the content. Invalid versions, malformed metadata, provenance provider/model mismatches, and content/block mismatches fail explicitly with `LlmError('INVALID_REPLAY_STATE')`. + +## Vocabulary differences + +- pi-ai tool-call arguments are parsed objects; the harness stores raw JSON strings. The adapter parses input and re-stringifies output. +- pi-ai reports failures as in-stream error events; these map to `finish {kind:'error'|'aborted'}` chunks. Provider-specific error text and usage signals evaluated against the resolved model's context window normalize overflow to `CONTEXT_WINDOW_EXCEEDED`. +- pi-ai folds reasoning tokens into output usage; there is no separate reasoning count to map. +- `GenerateOptions.stop` is rejected with `UNSUPPORTED_OPTION` because pi-ai's common streaming surface cannot guarantee it across providers. + ## App attribution -Every request carries the shared attribution header from dsh-llm's `attributionHeaders()`, passed through pi-ai's `headers` stream option (pi-ai merges caller headers last, so it always reaches the wire - the unit suite asserts arrival on the mock server, same as llm-deepseek). OpenRouter-specific app attribution headers are intentionally not sent by this adapter contract; they are deferred to a future explicit OpenRouter adapter or mode. See [dsh-llm § App attribution](../llm/README.md#app-attribution-attributionts). +Every request carries the shared attribution header from dsh-llm's `attributionHeaders()`, merged through pi-ai's `headers` stream option. Provider-specific app-attribution headers are not synthesized. See [dsh-llm § App attribution](../llm/README.md#app-attribution-attributionts). ## Dependency weight -pi-ai declares the openai/anthropic/google/mistral/AWS SDKs as install-time dependencies. They are lazy-loaded — only the openai SDK actually loads for this adapter — but they do land in `node_modules`. Accepted for a package whose purpose is design verification. +pi-ai installs several provider SDKs and lazy-loads the one selected by the catalog model. The dependency weight is isolated to this opt-in adapter package. ## Testing -Unit suites run against a local `node:http` mock SSE server (pi-ai's openai SDK happily talks to any base URL). Real-API coverage in `tests/adapter.e2e.ts` (`pnpm run test:e2e`, key-gated): V4 Flash + V4 Pro across all exposed reasoning levels (off/high/xhigh), the thinking+tools round trip, and a cross-adapter structural-equivalence check against llm-deepseek. +Unit tests use pi-ai catalog models redirected to local mock servers and cover provider/profile routing, native API selection, endpoint overrides, attribution, conversion, replay-state validation, and cross-provider/model replay within one adapter instance. Real-API coverage remains key-gated under `pnpm run test:e2e`. ## Model Experience -### DeepSeek request through pi-ai +### Provider request through pi-ai -**What the model sees**: The selected model receives the same logical system prompt, history, tools, stop sequences, and raw replayed tool arguments as the hand-written adapter. This package adds no prompt prose and removes pi-ai's own per-tool `strict` default to preserve that contract. +#### What the model sees -**Token effect**: Provider tokenization governs exact input.

Unrecorded transport metadata and usage accounting do not affect cache identity. ## Known Limitations and Deferred Work -- **`tool_choice` is not mapped** — same MVP contract as llm-deepseek. -- **In-history `system`-role messages fold into `user`-role wire messages** — pi-ai exposes a single `systemPrompt` slot, diverging from the hand-rolled twin's `role: 'system'` passthrough. -- **`LlmError.status` is never set** — pi-ai reports failures as in-stream events with no HTTP status, so error codes are regex-classified from the error text. -- **`buildModel` hardcodes descriptor metadata** — `contextWindow: 128000`, `maxTokens: 64000`, zero cost, identically for every registered model name; not configurable. -- **pi-ai's built-in retries are disabled (`maxRetries: 0`)** — failures surface immediately; retry policy belongs to `llm/stream` listeners. +- **Catalog membership is required** — custom model ids that are absent from the installed pi-ai catalog fail with `UNKNOWN_MODEL`, even when a provider profile supplies a custom endpoint. +- **`GenerateOptions.stop` is unsupported** — pi-ai's common stream options cannot guarantee stop-sequence behavior across providers, so the adapter rejects the field. +- **In-history `system` messages use pi-ai's common context conversion** — provider-specific placement follows pi-ai rather than a harness-owned wire override. +- **Provider HTTP status is unavailable** — pi-ai error events do not expose a stable HTTP status across providers; failures expose only stable harness error codes. diff --git a/packages/llm/llm-pi-ai/src/adapter.ts b/packages/llm/llm-pi-ai/src/adapter.ts index 4b93b5e87d..7f40c67da3 100644 --- a/packages/llm/llm-pi-ai/src/adapter.ts +++ b/packages/llm/llm-pi-ai/src/adapter.ts @@ -1,147 +1,101 @@ /** - * Pi-ai-backed DeepSeek adapter and design twin of the hand-rolled adapter. - * Both implementations must fit the same provider-neutral stream vocabulary. + * Generic pi-ai-backed implementation of the Harness LLM seam. + * * @module dsh-llm-pi-ai/adapter */ -import { stream as piStream } from '@earendil-works/pi-ai' -import type { Model } from '@earendil-works/pi-ai' -import { attributionHeaders, LlmAdapter } from '@deepseek-ai/dsh-llm' -import { CallId } from '@deepseek-ai/dsh-llm' -import type { GenerateOptions, StreamChunk } from '@deepseek-ai/dsh-llm' -import { toPiContext, toStreamChunks } from './convert.ts' +import { + getModels, + streamSimple, +} from '@earendil-works/pi-ai' +import type { + Api, + KnownProvider, + Model, + SimpleStreamOptions, +} from '@earendil-works/pi-ai' +import { attributionHeaders, LlmAdapter, LlmError } from '@deepseek-ai/dsh-llm' +import type { GenerateOptions, LlmModelInfo, StreamChunk } from '@deepseek-ai/dsh-llm' +import type { PiAiProviderProfile } from './config.ts' +import { toPiContext } from './context.ts' +import { toStreamChunks } from './stream.ts' -/** Reasoning levels surfaced by this adapter (DeepSeek wire: high|max). */ -export type PiAiReasoning = 'off' | 'high' | 'xhigh' - -/** Constructor options for {@link PiAiAdapter}; the plugin's `apply` resolves them from Config + environment. */ +/** Constructor options for {@link PiAiAdapter}. */ export interface PiAiAdapterOptions { - /** Bearer token pi-ai sends on every request. */ - apiKey: string - /** Endpoint base; `/chat/completions` is appended. */ - baseURL: string - /** Thinking level applied to every request ('off' disables thinking). */ - reasoning?: PiAiReasoning | undefined + /** Validated provider profiles this adapter instance owns. */ + profiles: readonly PiAiProviderProfile[] } /** - * Build the inline pi-ai model descriptor for one DeepSeek model name. - * @param modelId - harness model name; sent verbatim on the wire. - * @param options - adapter options; only `baseURL` is read here (key and reasoning apply per request, not per descriptor). - * @returns a descriptor with every DeepSeek compat flag explicit — pi-ai's URL-based auto-detection is never relied on. + * Resolve a catalog model dynamically and apply only the configured endpoint + * override, preserving the catalog's API/capability/compatibility metadata. */ -export function buildModel(modelId: string, options: PiAiAdapterOptions): Model<'openai-completions'> { +function resolveModel(profile: PiAiProviderProfile, modelId: string): Model<Api> { + const model = getModels(profile.provider as KnownProvider).find(candidate => candidate.id === modelId) as Model<Api> | undefined + if (model === undefined) { + throw new LlmError(`pi-ai provider "${profile.provider}" has no catalog model "${modelId}"`, 'UNKNOWN_MODEL') + } + return profile.baseURL === undefined ?

The union is derived from the merge-extensible `ContentBlockMap`, so plugins can add block types via declaration merging. Assistant messages produced by the loop also carry provider/model provenance and optional adapter-private replay state. Before dispatch, `LlmService` retains that state only when the historical provider route and target provider route are currently owned by the exact same adapter instance; the adapter then decides whether it can restore or convert the state across models/providers. The core block set is limited to blocks every shipping path honors — multimodal content (images, audio, …) has no core block type; a feature that needs one adds it via the map together with the adapter/UI/compaction support that honors it. Streaming is a raw chunk protocol (`block-start`, `text-delta`, `reasoning-delta`, `tool-call-delta`, `block-end`, `usage`, `finish`). `BlockAssembler` is the single shared implementation that assembles chunks into blocks/messages. ### Call configuration (`call-config.ts`) -`LlmCallConfig` is the model + sampling scalars of one conversation's requests (`model`, `temperature`, `maxTokens`, `stop` — each mapping 1:1 onto the same-named `GenerateOptions` field).

Adapters verify the wire header directly or through their library hook. See [the attribution Agent Note](../../../.agents/notes/implemented/architecture/2026-06-21-mandatory-app-attribution-headers.md). ### Classes - `LlmAdapter` — abstract base class for provider adapters. The only required method is `stream()`. - `BlockAssembler` — incrementally assembles raw chunks into complete content blocks and an assistant message. The agent loop feeds it raw chunks (logging them for replay) while reading the assembled blocks/message for history. - `HarnessError` — base class for the harness error taxonomy: a stable `code` string (distinct from the human `message`) plus `cause` chaining. Lives here, in the leaf package every other imports, so a single base is shared without a new dependency edge. Per-package errors (`LlmError`, `ToolArgsError`, `InvariantError`, …) extend it. `isHarnessError(value)` narrows at seams. -- `LlmError` — extends `HarnessError`; `code` string (`NO_ADAPTER`, `DUPLICATE_ADAPTER`, and adapter codes like `AUTH`/`RATE_LIMIT`) plus an optional numeric `status` when the failure came from a non-2xx provider response. +- `LlmError` — extends `HarnessError`; its stable `code` string (`NO_ADAPTER`, `DUPLICATE_ADAPTER`, and adapter codes like `AUTH`/`RATE_LIMIT`) is the programmatic failure contract. +- `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. ### Real adapters -Two adapters implement `LlmAdapter` on different internals: [`@deepseek-ai/dsh-llm-deepseek`](../llm-deepseek) uses hand-rolled fetch/SSE, while [`@deepseek-ai/dsh-llm-pi-ai`](../llm-pi-ai) uses `@earendil-works/pi-ai`. Both follow the `StreamChunk` conventions in `types.ts`: usage precedes finish, tool arguments remain raw strings, and errors take one of two sanctioned paths. See [the twin LLM adapters](../../../docs/rfc/implemented/architecture/2026-06-13-twin-llm-adapters.md) for the design rationale. +Two adapters implement `LlmAdapter` on different internals: [`@deepseek-ai/dsh-llm-deepseek`](../llm-deepseek) uses hand-rolled fetch/SSE for the `deepseek` route, while [`@deepseek-ai/dsh-llm-pi-ai`](../llm-pi-ai) dynamically resolves configured provider/model pairs through `@earendil-works/pi-ai`.

It advances one isolated fold per session from the durable log, so compaction and other pressure-sensitive plugins can share accounting without depending on `CompactService`. + +## Configuration + +| Key | Default | Contract | +|---|---:|---| +| `contextWindow` | `128000` | Positive integer service-wide context capacity. | + +The estimator intentionally uses one fixed heuristic: four characters per token plus structural overhead for roles, blocks, and request-envelope fields. `contextWindow` is the only deployment setting. Direct construction validates it; Loader mounts first apply the package's Schemastery shape validation. Unrecognized top-level keys are rejected. + +## Measurement contract + +`ctx.tokenMeter` directly exposes two operations: + +- `measure(session, requestHeader?)` returns request pressure and the current priced surface at one consumed-log revision. +- `estimateMessage(message)` prices one message with the fixed heuristic. + +`measure()` synchronizes once and returns one detached, deeply immutable snapshot. `totalTokens` is request-and-response pressure, while `surfaceTokens` is the surface-only heuristic total and equals the sum of `nodes[].tokens`. A `requestHeader` override affects pressure fields only; the surface fields still describe the current session. Every call clones the positional nodes, so measurement is O(surface). + +The fold tracks full request-header snapshots, step boundaries, surface appends and replacements, successful assistant messages, provider usage, and assistant-chunk provenance. Provider usage is reused only when the latest successful call's canonical request envelope matches the measured envelope and its total is no lower than that call's full heuristic anchor; a later success replaces the earlier anchor. Otherwise the complete current envelope and surface are estimated. Surface changes remain signed relative to a matching anchor, including negative deltas after shrinking replacements. + +Usage accounting sums disjoint input, cache-read, cache-write, and output buckets; reasoning is not added again.

Development and production read the same `cordis.yml`. + +Generated project scripts invoke `dsh-sdk` for dev, build, start, and config; typecheck runs `tsc -b` directly. HMR remains an explicit `cordis.yml` feature loaded by both dev and start. + +The runtime library exports `startSDK(source)` to load `.env` and `cordis.yml` and return the live context, and `runSDK(target)` to import a project module and invoke its `main(bootContext)` (`runSDK()` without a target delegates to `startSDK('./cordis.yml')`). `SdkBootContext` carries the raw forwarded `argv`, generic `args`, the absolute launcher `cwd`, and the `start`/`dev` mode. The launcher declares no project options: Node `parseArgs()` runs with zero schema, so valued flags use `--key=value`, bare flags become booleans, `--no-cache` becomes `args.cache = false`, and option names retain Node's spelling (`--max-depth=3` → `args['max-depth']`). + +`start` never builds. `dev` registers the project-installed tsx transform plus an exact package-name map from `plugins/*/package.json` to each `src/index.ts`, then follows the same start path. `build` invokes the project-installed tsdown and forwards its arguments; an absent tsdown config is a successful no-op. + +`config` requires a TTY. One feature tree selects the desired enabled set; changed rows are highlighted, Right changes finite feature options, required rows cannot be deselected, inconsistent rows show diagnostics, and custom/manual Cordis config entries support enable/disable. The workflow reconciles that target into one edit session. Review & Apply commits once, then NPM dependency changes trigger one package-manager install.

+Launcher-side telemetry primitives for the dsh-sdk toolchain. This is a plain library the launcher imports around each command; it is **not** a Cordis plugin, because `build` and first-init `create` never boot Cordis. Wiring the reporter into the launcher command dispatch and adding the telemetry consent feature to the `dsh-helper` catalog live in their owning packages, not here. + +| Export | Role | +|---|---| +| `SecretRedactor` | Conservative safety backstop: replaces secret-shaped values (secret-like keys, known token shapes, PEM blocks, URL credentials, high-entropy opaque tokens) with a placeholder in both parsed values (`redactValue`) and raw text (`redactText`). Never drops a field or line. | +| `ConsentResolver` | Parses (never boots) a project `cordis.yml` and reads the telemetry entry's enabled/disabled state as consent; `DO_NOT_TRACK`/CI env force a hard opt-out. | +| `buildTelemetryPayload` | Assembles `{command, durationMs, success, cordisYmlContent, packageJsonContent}`, running the redactor over the full `cordis.yml` and `package.json` text. Never reads `.env`; `package.json` ships only alongside a `cordis.yml`, so a command run in a non-SDK directory never uploads that directory's unrelated manifest. | +| `getOrCreateAnonymousId` | Random UUID persisted in a per-user GLOBAL config file (never in the project, never derived from git). | +| `TelemetryReporter` | Fire-and-forget send: `report()` never blocks or throws; delivery resolves on every path; `flush()` optionally drains in-flight sends within a cap. | + +Consent is carried by the telemetry entry in `cordis.yml`, so disabling telemetry is disabling that entry. Telemetry reports by default and is off only when a present telemetry entry is explicitly `disabled`: a missing `cordis.yml` (first `create`), an enabled entry, or a `cordis.yml` with no telemetry entry all report. `DO_NOT_TRACK`/CI always deny.

A `sessions` row is written only by the first `append` — its existence is the lazy-materialization signal (`list` reports exactly the sessions that have a row), so no separate column is needed. The repository's Node range supports unflagged `node:sqlite`. The database enables foreign keys and uses the configured journal mode (`wal` by default; use a rollback mode where WAL shared-memory files are unsuitable). `PRAGMA user_version` stores the table-layout version; databases with any other version are rejected because this unreleased format has no migrations. +On filesystems with POSIX modes, the backend requests mode `0700` for missing directories and exclusively creates a missing database with mode `0600` before SQLite opens it; the process umask may further restrict both. New WAL, shared-memory, and persistent rollback-journal sidecars receive the database's resulting owner-only mode. Existing directories, database files, and sidecars keep their modes; filesystem setup errors other than an existing database fail initialization. These defaults prevent incidental exposure through a permissive process umask, but do not protect database confidentiality or integrity when another principal can replace the database entry in its parent directory. + ## Contract semantics over rows - **Append = a transaction.** `append` runs `BEGIN`/`COMMIT` around the batch: it materializes the `sessions` row (if still lazy) and INSERTs every event, asserting the contiguous-seq contract first (the first event's `seq` must equal the stored next-seq). A mid-batch failure (a UNIQUE violation on a duplicated seq) rolls back entirely, so the stored log and the in-memory cursor stay consistent. (`load()` already balanced the stored log, so `append` never has to repair a crash tail.) - **Lazy materialization.** `create()` records intent in memory only — no row is written until the first `append`. A created-but-never-appended session has no `sessions` row, so it is absent from `list()` (which reports exactly the sessions that have a row). -- **Interrupted-turn close on load.** `load()` implements the shared [crash-recovery contract](../../../docs/rfc/implemented/architecture/2026-06-14-session-persistence.md): preserve the valid interrupted turn, append its synthetic closing events in one transaction, and remove only a torn tail row.

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). ## Model Experience None, as this test-only harness records, normalizes, and compares ACP transcripts without changing the agent's assembled model request. +#### KV Cache effect + +None; this package neither assembles nor sends a provider request. + ## Known Limitations and Deferred Work - **Session harvest is JSONL-only** — `runScenario` collects persisted `.jsonl` logs, so an example composed over the SQLite persistence backend has no snapshot path. diff --git a/packages/support/acp-snapshot/package.json b/packages/support/acp-snapshot/package.json index d206b08161..9cf18e7824 100644 --- a/packages/support/acp-snapshot/package.json +++ b/packages/support/acp-snapshot/package.json @@ -1,6 +1,6 @@ { "name": "@deepseek-ai/dsh-acp-snapshot", - "description": "ACP snapshot suite kit: real-subprocess scenario harness, golden normalizers, and the suite factory behind the keyless snapshot tier", + "description": "ACP test kit: shared subprocess launcher, snapshot scenario harness, expected-output normalizers, and suite factory", "version": "0.0.1", "private": true, "type": "module", @@ -23,7 +23,7 @@ "license": "BSD-3-Clause", "dependencies": { "@agentclientprotocol/sdk": "0.25.1", - "tsx": "^4.22.4", + "@deepseek-ai/dsh-loader-smoke": "workspace:*", "vitest": "^4.1.8" }, "peerDependencies": { diff --git a/packages/support/acp-snapshot/src/harness.ts b/packages/support/acp-snapshot/src/harness.ts index 7fd8cf25a8..50d7763609 100644 --- a/packages/support/acp-snapshot/src/harness.ts +++ b/packages/support/acp-snapshot/src/harness.ts @@ -1,65 +1,46 @@ /** - * Shared ACP snapshot subprocess harness.

The deployment must not compose a stdout logger; diagnostics belong on stderr. ## Shutdown and exit semantics -A `shutdown` request flushes its response, disposes the plugin fiber, then exits 0.

This includes `loader/src/config/isolate.ts` using `declare module './entry.ts'`. 5. **`schemastery/tsdown.config.ts` and `logger-console/tsdown.config.ts`**: ours, not upstream files — per-package build-shape overrides (dual ESM+CJS output; separate node/browser entries) for the repo-root tsdown build. They read the JS emitted under `lib/types` and then write the publish runtime entries under `lib/`. Like the regenerated tsconfigs, they are not part of the upstream sync surface. 6. **`cordis/src/fiber.ts` lifecycle hardening**: locally closes three reentrant disposal gaps. An effect's owner-list wrapper is registered before its setup body runs, so an unload begun from inside setup awaits setup and every collected cleanup; synchronous setup failure removes the wrapper and rolls back collected cleanup. Async cleanup stays owner-visible until quiescence, and Cordis's internal effect composition joins an already-running cleanup while repeated public disposer calls retain their upstream single-shot result. Effect creation is rejected while the owner is `UNLOADING` (while `PENDING` and `LOADING` remain legal), preventing cleanup-time registrations from escaping the unload snapshot. Child fibers register and receive their parent-owned disposer before `internal/plugin` publication, resolve dependency declarations added by that notification before activation, drain effects attached while pending, skip plugin execution when reentrant disposal invalidates the load epoch before its first checkpoint, and contain teardown-notification failures per observer so one callback cannot starve peers or interrupt ownership cleanup. +7. **`cordis/src/*.ts` JSDoc enrichment**: added `@param`/`@returns` tags and contract documentation (disposal semantics, waterfall veto, bail conditions, error cases) across the public plugin-author surface — `Context` (class, statics, and the `Context` interface properties incl. `root`), `EventsService`, `Fiber`, `RegistryService`, `ReflectService`, `Service`, `LoggerService` and their `declare module './context.ts'` overloads. Comment-only; no code changes. Motivation: the website API-reference generator renders these docs and hard-errors on undocumented members.
