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 `` with `Instructions from: ` 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 `` 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: ` 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: `, 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: ` 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 `` 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>`: 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.

Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. 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.

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?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const — no oneOf/pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), `model` (override). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const — no oneOf/pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), `model` (override). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`.

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 + +The following workspace instructions may be relevant to your work.

They do not override system, developer, or direct user instructions. + +... + +``` + +A same-file edit starts with `Updated instructions from: ` 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: ` followed by `The previously loaded instructions from this file no longer apply.` Literal `` 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 `` framing. This is caller-selected with `envelope: 'raw'`; ordinary injected context still receives the canonical `` 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 first because a later tool aborted the step and the loop discarded its context buffer, 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. + +**Token effect**: The rendered baseline is frozen and resent on every request in that loop instance. `maxBytes` bounds the complete message, broader files are omitted before the most-specific file is truncated, and an empty chain contributes zero tokens. + +#### Baseline instruction template + +```markdown + +The following workspace instructions may be relevant to your work. Use them as guidance when applicable. More specific instructions take precedence over broader ones. They do not override system, developer, or direct user instructions. + +Instructions from: ~/.dsh/AGENTS.md + + + +Instructions from: AGENTS.md + + + +``` + +### Newly discovered scope context + +**What the model sees**: After a successful first-party filesystem call reaches a deeper directory, the next request includes one retained raw `context/message` with the newly applicable instruction file. + +**Token effect**: Each discovered scope adds bounded history tokens until compaction. Unchanged content is suppressed by visible session state plus version/digest comparison, and Code Mode defers the same message until after the outer `run_code` result. + +#### Additional instruction template + +```markdown + +Additional instructions from: packages/app/AGENTS.md + +These instructions apply to work under `packages/app`. Use them as guidance when relevant; more specific instructions take precedence. They do not override system, developer, or direct user instructions. + + + +``` + +### Changed or removed instruction context + +**What the model sees**: A changed file produces `Updated instructions from: ` plus its replacement content; a candidate switch also names the previous path. A removed final candidate produces the removal notice below. + +**Token effect**: Each confirmed change or removal is one retained history message bounded by `maxBytes`. Provider failures add no message, and an update omitted by the budget remains eligible for a later filesystem touch. + +#### Removal notice + +```markdown + +Instructions removed: packages/app/AGENTS.md + +The previously loaded instructions from this file no longer apply. + +``` + +## Known Limitations and Deferred Work + +- **Discovery follows structured fs tools, not shell navigation** — a `bash` command that changes directories does not trigger nested instruction discovery because shell syntax and per-call shell state are not a reliable filesystem seam. +- **Refresh is touch-driven** — there is no watcher; external edits become visible on the next successful first-party `read`, `write`, or `edit`, or when a resumed loop recomposes its prefix. +- **Candidate semantics stay intentionally small** — lowercase names, `.claude/rules/`, and `@path` imports are not interpreted; same-directory names such as `CLAUDE.local.md` require explicit `instructionFileCandidates` configuration. +- **Instruction content is bounded, not summarized** — over-budget broad files are omitted and the most-specific file may be truncated; the plugin never asks a model to compress instruction prose. diff --git a/packages/context/workspace-context/package.json b/packages/context/workspace-context/package.json new file mode 100644 index 0000000000..7f704c838a --- /dev/null +++ b/packages/context/workspace-context/package.json @@ -0,0 +1,51 @@ +{ + "name": "@deepseek-ai/dsh-workspace-context", + "description": "Workspace context loader for AGENTS.md/CLAUDE.md instruction files", + "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", + "peerDependencies": { + "@deepseek-ai/dsh-agent": "^0.0.1", + "@deepseek-ai/dsh-fs": "^0.0.1", + "@deepseek-ai/dsh-llm": "^0.0.1", + "@deepseek-ai/dsh-paths": "^0.0.1", + "@deepseek-ai/dsh-session": "^0.0.1", + "@deepseek-ai/dsh-tools": "^0.0.1", + "cordis": "^4.0.0-rc.6" + }, + "dependencies": { + "schemastery": "^3.18.0" + }, + "devDependencies": { + "@cordisjs/plugin-loader": "workspace:^", + "@deepseek-ai/dsh-agent": "workspace:^", + "@deepseek-ai/dsh-agent-loop": "workspace:^", + "@deepseek-ai/dsh-fs": "workspace:^", + "@deepseek-ai/dsh-fs-local": "workspace:^", + "@deepseek-ai/dsh-llm": "workspace:^", + "@deepseek-ai/dsh-llm-deepseek": "workspace:^", + "@deepseek-ai/dsh-paths": "workspace:^", + "@deepseek-ai/dsh-session": "workspace:^", + "@deepseek-ai/dsh-system-prompt": "workspace:^", + "@deepseek-ai/dsh-tool-fs": "workspace:^", + "@deepseek-ai/dsh-tools": "workspace:^", + "cordis": "^4.0.0-rc.6" + } +} diff --git a/packages/context/workspace-context/src/config.ts b/packages/context/workspace-context/src/config.ts new file mode 100644 index 0000000000..c4bdd663c7 --- /dev/null +++ b/packages/context/workspace-context/src/config.ts @@ -0,0 +1,82 @@ +/** + * Configuration normalization for workspace instruction discovery and rendering. + * + * @module @deepseek-ai/dsh-workspace-context/config + */ + +import z from 'schemastery' +import { resolveDshHome } from '@deepseek-ai/dsh-paths' + +const DEFAULT_PROJECT_ROOT_MARKERS = ['.git'] as const +const DEFAULT_INSTRUCTION_FILE_CANDIDATES = ['AGENTS.md', 'CLAUDE.md'] as const +const DEFAULT_MAX_SOURCE_BYTES = 1_048_576 +const RESERVED_PATH_SEGMENTS = new Set(['', '.', '..']) + +/** User-facing workspace instruction loader configuration. */ +export interface Config { + /** Harness home containing the fixed user-global `AGENTS.md`;

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 `:code:`; `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.

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`). diff --git a/packages/fs/fs-local/src/fsio.ts b/packages/fs/fs-local/src/fsio.ts index fba2a240eb..360145e8c8 100644 --- a/packages/fs/fs-local/src/fsio.ts +++ b/packages/fs/fs-local/src/fsio.ts @@ -7,8 +7,8 @@ import { randomUUID } from 'node:crypto' import { createReadStream } from 'node:fs' -import { chmod, mkdir, open, readFile, realpath, readdir, rename, rm, stat } from 'node:fs/promises' -import type { Dirent, Stats } from 'node:fs' +import { chmod, lstat, mkdir, open, readFile, realpath, readdir, rename, rm, stat } from 'node:fs/promises' +import type { BigIntStats, Dirent, Stats } from 'node:fs' import { basename, dirname, join, resolve } from 'node:path' import { TextDecoder } from 'node:util' import { FsError, FsTargetKey, FsVersion } from '@deepseek-ai/dsh-fs' @@ -63,9 +63,9 @@ async function readFileAbortable(absolutePath: string, verb: 'read' | 'edit', si } } -/** Opaque version token from a stat: mtime (ns precision) + size. */ -function versionOf(info: Stats): FsVersion { - return FsVersion(`${info.mtimeMs}:${info.size}`) +/** Opaque version token from high-resolution identity and freshness metadata. */ +function versionOf(info: BigIntStats): FsVersion { + return FsVersion(`${info.dev}:${info.ino}:${info.size}:${info.mtimeNs}:${info.ctimeNs}`) } /** @@ -98,6 +98,14 @@ export interface PathInfo { size: number } +/** Result of probing a path without following the final symlink component. */ +export interface PathLinkInfo { + version: FsVersion + mode: number + type: 'file' | 'directory' | 'symlink' | 'other' + size: number +} + /** One local directory child with a resolved target and cheap metadata. */ export interface LocalDirEntry { name: string @@ -150,22 +158,62 @@ export async function resolveLocalTarget(cwd: string, path: string): Promise( + absolutePath: string, + readStats: (path: string) => Promise, +): Promise { + try { + return await readStats(absolutePath) + } catch (error: unknown) { + // ENOENT (no such file) and ENOTDIR (a parent segment is a file) both mean + // the target is absent; any other metadata failure is a real permission/IO + // fault. + /* v8 ignore next -- a non-ENOENT/ENOTDIR metadata failure needs a permission/IO fault; surface it. */ + if (!isENOENT(error) && !isENOTDIR(error)) throw error + return null + } +} + /** * Probe a path for its version, mode, type, and size.

The fixed tags are `py3-none-manylin ## Zero-config design -The runtime binary always demands an explicit config (`$DSH_CORDIS_CONFIG`, or a config path as an argv positional argument) and exits loudly without one — that hard semantic is part of the runtime's design and this package does not soften it. The bin (`dsh-jsonrpc-agent`) boots only the plugins the config lists; the serving surface (the stdio JSON-RPC server) is itself one of its entries (`@deepseek-ai/dsh-jsonrpc`), and without it the booted agent has no channel to the outside. This package checks in `runtime/cordis.yml` with the JSON-RPC serving entry, agent core, a preloaded DeepSeek adapter, JSONL persistence, and local bash. The adapter reads `DEEPSEEK_API_KEY` and `DEEPSEEK_BASE_URL`, while persistence and bash use `DSH_SESSION_ROOT` and `DSH_CWD` with manual-run fallbacks. When the caller uses no explicit config channel, the `deepseek_harness` client injects that file's path via `DSH_CORDIS_CONFIG` (injection conditions: [sdk README](../sdk/README.md)). Zero-config is thus an explicit, visible parameter pass in the wrapper, not a hidden fallback in the runtime. +The runtime binary always demands an explicit config (`$DSH_CORDIS_CONFIG`, or a config path as an argv positional argument) and exits loudly without one — that hard semantic is part of the runtime's design and this package does not soften it. The bin (`dsh-jsonrpc-agent`) boots only the plugins the config lists; the serving surface (the stdio JSON-RPC server) is itself one of its entries (`@deepseek-ai/dsh-jsonrpc`), and without it the booted agent has no channel to the outside. This package checks in `runtime/cordis.yml` with the JSON-RPC serving entry, agent core, a preloaded DeepSeek adapter, JSONL persistence, local bash, and a local filesystem provider for bounded workspace-instruction loading. The adapter reads `DEEPSEEK_API_KEY` and `DEEPSEEK_BASE_URL`, while persistence, bash, and the filesystem provider use `DSH_SESSION_ROOT` and `DSH_CWD` with manual-run fallbacks. When the caller uses no explicit config channel, the `deepseek_harness` client injects that file's path via `DSH_CORDIS_CONFIG` (injection conditions: [sdk README](../sdk/README.md)). Zero-config is thus an explicit, visible parameter pass in the wrapper, not a hidden fallback in the runtime. diff --git a/python/sdk-runtime/README.zh.md b/python/sdk-runtime/README.zh.md index 30723d6d78..99d57c6f90 100644 --- a/python/sdk-runtime/README.zh.md +++ b/python/sdk-runtime/README.zh.md @@ -26,4 +26,4 @@ exe 缺失时抛出 `FileNotFoundError`，并写明两种获取途径：在 deep ## 零配置设计 -运行时二进制始终要求显式配置（`$DSH_CORDIS_CONFIG`，或作为 argv 位置参数的配置路径），缺了就报错退出——这一硬语义是运行时设计的一部分，本包不软化它。`bin`（`dsh-jsonrpc-agent`）只启动配置里列出的插件；对外服务接口（stdio JSON-RPC 服务器）也是其中一个条目（`@deepseek-ai/dsh-jsonrpc`），缺了它，启动出的 agent 就没有对外通道。本包检入的 `runtime/cordis.yml` 包含 JSON-RPC 服务条目、`agent-core`、预载的 DeepSeek 适配器、JSONL 持久化与本地 bash。DeepSeek 适配器读取 `DEEPSEEK_API_KEY` 与 `DEEPSEEK_BASE_URL`，持久化与 bash 则使用 `DSH_SESSION_ROOT` 和 `DSH_CWD`，并为手动运行提供回退值。调用方未使用任何显式配置通道时，`deepseek_harness` 客户端把该文件路径注入 `DSH_CORDIS_CONFIG`（注入条件见 [sdk README](../sdk/README.md)）。因此，零配置是包装层中一次显式、可见的参数传递，而不是运行时中的隐藏回退。 +运行时二进制始终要求显式配置（`$DSH_CORDIS_CONFIG`，或作为 argv 位置参数的配置路径），缺了就报错退出——这一硬语义是运行时设计的一部分，本包不软化它。`bin`（`dsh-jsonrpc-agent`）只启动配置里列出的插件；对外服务接口（stdio JSON-RPC 服务器）也是其中一个条目（`@deepseek-ai/dsh-jsonrpc`），缺了它，启动出的 agent 就没有对外通道。本包检入的 `runtime/cordis.yml` 包含 JSON-RPC 服务条目、`agent-core`、预载的 DeepSeek 适配器、JSONL 持久化、本地 bash，以及用于有界加载工作区指令的本地文件系统 provider。DeepSeek 适配器读取 `DEEPSEEK_API_KEY` 与 `DEEPSEEK_BASE_URL`，持久化、bash 和文件系统 provider 则使用 `DSH_SESSION_ROOT` 和 `DSH_CWD`，并为手动运行提供回退值。调用方未使用任何显式配置通道时，`deepseek_harness` 客户端把该文件路径注入 `DSH_CORDIS_CONFIG`（注入条件见 [sdk README](../sdk/README.md)）。因此，零配置是包装层中一次显式、可见的参数传递，而不是运行时中的隐藏回退。 diff --git a/python/sdk-runtime/package.json b/python/sdk-runtime/package.json index 7fba79083a..a9c0055a02 100644 --- a/python/sdk-runtime/package.json +++ b/python/sdk-runtime/package.json @@ -33,6 +33,7 @@ "@deepseek-ai/dsh-llm-deepseek": "workspace:^", "@deepseek-ai/dsh-llm-pi-ai": "workspace:^", "@deepseek-ai/dsh-permission": "workspace:^", + "@deepseek-ai/dsh-paths": "workspace:^", "@deepseek-ai/dsh-repeat-tool-guard": "workspace:^", "@deepseek-ai/dsh-sandbox": "workspace:^", "@deepseek-ai/dsh-scope": "workspace:^", @@ -70,6 +71,7 @@ "@deepseek-ai/dsh-web-search-deepseek": "workspace:^", "@deepseek-ai/dsh-web-search-exa": "workspace:^", "@deepseek-ai/dsh-web-search-perplexity": "workspace:^", + "@deepseek-ai/dsh-workspace-context": "workspace:^", "@deepseek-ai/dsh-workflow": "workspace:^", "@deepseek-ai/dsh-workflow-workerthread": "workspace:^", "cordis": "workspace:^" diff --git a/python/sdk-runtime/src/deepseek_harness_runtime/runtime/cordis.yml b/python/sdk-runtime/src/deepseek_harness_runtime/runtime/cordis.yml index a47dcc26a7..ac61a8eb15 100644 --- a/python/sdk-runtime/src/deepseek_harness_runtime/runtime/cordis.yml +++ b/python/sdk-runtime/src/deepseek_harness_runtime/runtime/cordis.yml @@ -9,6 +9,9 @@ # Agent spine; the SDK server creates agents per sessionId. - id: agent-core name: '@deepseek-ai/dsh-agent-spine-demo' + config: + workspaceContext: + maxBytes: 65536 # Stock DeepSeek adapters.
