That primitive is intentionally low-level. It lives on `dsh-session` as `ctx.sessions.create(id, { seed })`, while durable metadata such as `parentSession` and `seedLength` is stored on the out-of-log `SessionHeader` introduced by [session persistence](../../implemented/architecture/2026-06-14-session-persistence.md). The same mechanics already support in-process subagent fork children and replay routing for forked child logs. + +What is missing is a reusable product service for ordinary session forking. Putting that directly on `dsh-session` would make a derived workflow part of the core log API, even though the core session package should stay focused on append-only storage, derived history, and lifecycle events. The harness architecture prefers optional capability plugins over widening the core spine; [event-sourced sessions](../../implemented/architecture/2026-06-11-event-sourced-sessions.md) provide the log semantics, and [capability seams](../../implemented/architecture/2026-06-13-capability-seams.md) provide the extension pattern. + +The main semantic hazard is the fork boundary. A session event log is only a valid seed when it is contiguous and balanced. Forking inside an active turn would copy an open `turn/start`, possibly an open `step/start`, and possibly dangling tool calls. That violates the turn-enclosure and provider-transcript invariants, and it creates a misleading child history that appears to have participated in an unfinished parent turn. The existing [subagent seam](../../implemented/feature/2026-06-21-subagent-capability-seam.md) deliberately solves a different problem: a tool-triggered subagent fork usually happens while the parent turn is open, so `dsh-subagent-fork` clips the seed to the parent's last completed-turn prefix. A general session fork should not silently clip; it should reject attempts made away from a boundary. + +## Decision + +The shipped design adds an optional product package, `@deepseek-ai/dsh-session-fork`, under `packages/session-fork/session-fork`. It registers `ctx.sessionFork` and depends only on `cordis` plus the `dsh-session` vocabulary/service. No new session event types, persistence methods, ACP methods, agent-loop hooks, or subagent behavior are added in the first cut. + +The service exposes two operations: + +```ts ignore-check +type SessionForkSource = Session | SessionId + +interface SessionForkSeed { + source: Session + seed: SessionEvent[] + meta: { + parentSession: SessionId + seedLength: number + cwd?: string + } +} + +interface ForkSessionOptions { + source: SessionForkSource + sessionId?: SessionId +} + +class SessionForkService extends Service { + snapshot(source: SessionForkSource): SessionForkSeed + fork(options: ForkSessionOptions): Session +} +``` + +`snapshot()` is the reusable half. It resolves only live sessions from `ctx.sessions`; v1 does not load unloaded persisted sessions by id. It validates the source is at a turn boundary, deep-clones the source events, and returns the seed plus metadata a caller can pass to a later session or agent creation path. This shape keeps the fork computation reusable for future ACP or agent-facing consumers without coupling this service to `ctx.agents`. + +`fork()` is the convenience half. It calls `snapshot()`, then creates a live child session via `ctx.sessions.create(sessionId, { seed, meta })`. The child inherits the source session's `cwd`, stamps `parentSession` to the source id, and sets `seedLength` to the seeded prefix length. When `sessionId` is omitted, `SessionStore` generates one using its existing id policy. + +The boundary rule is structural: an empty source log is forkable, and any source whose last event is `turn/end` is forkable regardless of the turn-end reason (`completed`, `aborted`, `error`, `disposed`, `max-tokens`, `interrupted`, or a future merge-extensible reason). Any non-empty source whose last event is not `turn/end` is inside a turn or otherwise not at the boundary and is rejected with a typed `SessionForkError` code. This is intentionally stricter than `dsh-subagent-fork`, whose completed-prefix clipping remains unchanged because it serves tool-time delegation rather than user/session branching. + +## Consequences + +The feature is a small capability seam rather than a change to `dsh-session`: the core log keeps its low-level seed primitive, while `dsh-session-fork` owns policy, error taxonomy, and convenience creation. Persistence continues to work through existing `session/created` and `session/flush` behavior: a forked child starts life with seeded events, so existing backends persist that seed once and preserve `parentSession` / `seedLength` in the header. + +The v1 scope deliberately excludes ACP `session/fork`, unloaded persisted-session forking, model-facing tools, and subagent refactors. Those can consume `snapshot()` later. If a future ACP method is added, it should advertise the capability only after it has transcript/snapshot coverage; this RFC adds no editor-facing updates, so no ACP snapshot is required now.

Running them as one ordered job makes the workflow wall clock equal the sum of those gates, and running the whole chain on multiple Node versions spends the same expensive repo-wide signal twice when the compatibility question is narrower than the full quality suite. + +The hard part is the artifact boundary. `publint`, `verify-node-next-types`, and built-bin smoke tests need the built `lib/` outputs, while most gates only need source and dependencies. A blind fan-out either races those artifact consumers before `pnpm run build` has emitted declarations and bundles, or repeats the build in every artifact-dependent job. + +## Decision + +[CI](../../../../.github/workflows/ci.yml) uses Node 24 as the primary quality lane and fans out independent source-only work into matrix jobs. The `quality` matrix runs constraints, typecheck, lint, coverage, snapshot replay, and the echo-agent demo smoke independently. The `docs` matrix expands the `doc-sync` members into leaf jobs, including the RFC classification and format gates, so documentation failures report at the gate that failed instead of hiding behind one aggregate step. + +Build output is produced once by a `build` job and uploaded as a short-retention artifact. Artifact consumers run behind that boundary: the `artifact-gate` matrix downloads the built package tree and runs `pnpm run hygiene` plus the built-bin smoke tests. Node-version compatibility stays explicit but narrower: the Node 26 lane runs typecheck and unit tests, while the full quality/documentation/artifact surface runs on the package engine floor. + +Both CI workflows cache the pnpm store after enabling Corepack. The real-API e2e workflow keeps its serial test execution because the e2e config deliberately disables file parallelism for API-quota stability; its speedup is dependency-cache reuse, not concurrent model calls. + +## Alternatives considered + +- **Keep the full serial chain in a Node matrix** - simplest to reason about, but it duplicates repo-wide gates that do not produce Node-version-specific signal and leaves every PR waiting for the sum of all gates. +- **Run every gate independently with no build artifact handoff** - maximizes fan-out, but the publication and built-bin checks are defined over built `lib/` outputs and would either fail, skip, or rebuild the same tree in several jobs. +- **Build inside every artifact-dependent job** - preserves correctness but shifts the bottleneck from the serial chain to repeated `tsc -b` and bundling work. +- **Parallelize real-API e2e files** - rejected because the e2e suite's Vitest config uses `fileParallelism: false` to stay within shared API-key quota and avoid rate-limit flakes. + +## Consequences + +PR feedback arrives as many smaller checks rather than one large status. That makes failures easier to localize and lets independent gates finish as soon as their own runner is done, at the cost of more GitHub job setup overhead and a larger workflow file. + +The split introduces a maintenance obligation: when `package.json` adds or removes a `doc-sync` member, the docs matrix needs the matching leaf job.

Lefthook already runs top-level jobs in parallel, but aggregate jobs such as `pnpm run hygiene` and `pnpm run doc-sync` hide long sequential chains inside one job. The hook can therefore be configured as parallel while still waiting on serial subcommands whose members are independent. + +`publint` has the same shape one level lower. Each package is linted independently against its own manifest and built output, but the runner loops through every package in order. On this repo that makes one package-publication gate consume time proportional to the number of packages even though the checks do not share mutable state. + +## Decision + +[lefthook.yml](../../../../lefthook.yml) expands the pre-push hook into leaf jobs for the unit suite, snapshot suite, `hygiene` members, `doc-sync` members, and module-graph freshness. The leaf list keeps the same gate vocabulary as the package scripts, including RFC classification and RFC format, but lets lefthook schedule the independent checks concurrently and report each failure by its own job name. + +[scripts/publint-all.ts](../../../../scripts/publint-all.ts) discovers the package list from `packages//` and runs `publint` with a worker pool sized from `availableParallelism()`. `DSH_PUBLINT_CONCURRENCY` can cap or raise the worker count for local machines and CI runners with different resource profiles. Results are buffered per package and printed in deterministic package order, so parallel execution does not scramble each package's log block. + +The aggregate package scripts remain the source of truth for CI and ad hoc local runs. The hook is a parallel execution plan over their member gates, not a replacement vocabulary. + +## Alternatives considered + +- **Keep aggregate `hygiene` and `doc-sync` jobs in the hook** - simpler config, but it leaves most of the pre-push wall clock inside serial command chains that lefthook cannot see or schedule. +- **Background subcommands inside shell scripts** - can parallelize work, but it loses lefthook's job names, per-job timing, and failure grouping, and makes signal handling harder to reason about. +- **Declare one publint lefthook job per package** - exposes maximum parallelism, but it turns the hook into a hand-maintained package inventory that drifts exactly when new packages are added. +- **Run publint with unbounded concurrency** - minimizes elapsed time on small machines only by gambling with process count, memory pressure, package tarball creation, and readable logs. + +## Consequences + +The hook's critical path becomes the slowest real gate instead of the sum of hidden gate chains. Lefthook reports per-job timing for every leaf gate, so a slow local checkpoint points at the gate that actually dominates the run. + +The hook file is longer and must track the member list of `hygiene` and `doc-sync`. That duplication is acceptable because the purpose of the hook is scheduling, while `package.json` remains the command vocabulary that CI and humans call directly. + +`publint-all.ts` becomes asynchronous code and buffers command output instead of inheriting stdio live.

Auto-compaction runs on the serial `agent/pre-step` loop seam (fired once per step, after `turn/start` and BEFORE the step opens and its request history is derived), not the `agent/request` waterfall: compaction mutates the session surface in place — with its log-only `compact/*` records landing cleanly outside any step — and the loop derives the request from the already-compacted surface. Retention is turn-agnostic — the only structural guard is tool-pairing balance (a compacted region's edges are balanced cuts on the surface, so it never splits a step's tool-calls from their results), so a single runaway turn that alone exceeds the window compacts its own early closed steps rather than being retained verbatim.

Retention is **turn-agnostic** — turn boundaries play no role, so a single runaway turn that alone exceeds the window compacts its OWN early closed steps rather than being retained verbatim (the failure mode that motivated dropping turn-protection: a tool-heavy turn must stay compactable or the harness dies exactly when compaction is needed). The only structural guard is **tool-pairing balance**: the compacted region's edges are balanced cuts on the surface (no unanswered tool-call crosses either edge), so it never splits a step's `assistant/message` tool-calls from their `tool/result`s. When the only compactable content left is an un-splittable open tail step, it declines (returns `null`) and retries once an older step closes. **Single-unit overflow is out of scope, by design**: if one retained unit (a single closed step, or a large pasted `user/message`) ALONE exceeds the budget, compaction cannot help and the call may go out over-budget — bounding an individual unit's size is a separate concern. `compactRegion()` enforces tool-pairing balance strictly, throwing on a boundary that would split a step. `dsh-session` exports `isToolPairingBalanced` for the check. - **Dynamic convergence** — no static summary-length config pretends to bound what the model will write. If framing/estimator/system overhead leaves the compacted surface above threshold, `compactIfNeeded()` re-compacts the head checkpoint up to `compactionRetries` extra times; if it still cannot get below threshold, it throws. A summary whose estimated stored size is not smaller than the shadowed content fails closed before it mutates the surface. -- **Summarization** — `summarize()`: a `GenerateOptions` request assembled via `BlockAssembler` with a fixed system prompt that asks for a structured checkpoint (Primary Request and Intent · Key Technical Concepts · Files and Code · Errors and Fixes · Pending Tasks · Current Work · Next Step · Critical Context), every section mandatory, exact paths/commands/identifiers preserved. The request runs through the `agent/request` waterfall before `ctx.llm.stream()`, so router agents that choose the concrete model there also route compaction summaries. `maxTokens` is the provider-side generation cap; only text blocks from the model's reply are kept before the checkpoint is stored (reasoning is dropped so private chain-of-thought never leaks into the durable summary, and a stray `tool-call` is dropped so the synthesized `user/message` summary cannot land an orphaned call with no matching `tool-result`). The compacted region is flattened to a plain-text transcript first: text and reasoning contribute their text, and every non-text block (tool-call, tool-result, plugin-added types) contributes a type-tagged placeholder (`[tool-call: name(args)]`, `[tool-result: …]`, …) so the summarizer is told what existed rather than silently dropping it. +- **Summarization** — `summarize()`: a `GenerateOptions` request assembled via `BlockAssembler` with a fixed system prompt that asks for a structured checkpoint (Primary Request and Intent · Key Technical Concepts · Files and Code · Errors and Fixes · Pending Tasks · Current Work · Next Step · Critical Context), every section mandatory, exact paths/commands/identifiers preserved. The request is a direct one-shot `ctx.llm.stream()` call — NOT a loop step, so it does not run `agent/request` (that seam shapes the loop's conversation requests); the model comes from `summarizationModel` falling back to the agent's own, and per-call routing happens at `llm/stream` like any other direct call. `maxTokens` is the provider-side generation cap; only text blocks from the model's reply are kept before the checkpoint is stored (reasoning is dropped so private chain-of-thought never leaks into the durable summary, and a stray `tool-call` is dropped so the synthesized `user/message` summary cannot land an orphaned call with no matching `tool-result`).

Because region compaction can be invoked manually, a surface may hold several checkpoints, so the framing does not claim everything after it is recent or verbatim. The tags make a prior checkpoint detectable in the transcript on the next compaction cycle: the summarization prompt then instructs the model to merge it in place (preserve still-true facts, drop stale ones) rather than re-summarize it verbatim — a cheap incremental merge that needs no extra log/event machinery. The unframed summary stays on the `compact/summary` provenance event. - **Surface mutation** — `compactRegion()` appends the `compact/start` → `compact/summary` → `compact/end` log records and the single `user/message` replace node carrying the framed summary (see the interface README). - **Auto-compaction** — an `agent/pre-step` listener delegates to `compactIfNeeded()` before every step (not just a turn's first — a tool-heavy turn grows the surface mid-turn, so a runaway turn still compacts, and per-step firing is the only moment to rescue it before overflow). `agent/pre-step` is a serial (awaited, in-order) surface-mutation checkpoint that fires after `turn/start` and BEFORE the step opens (`step/start`) and its request history is derived, so compaction mutates the surface — with its log-only `compact/*` records landing cleanly outside any step — and the loop derives once from the result: no double-derive, and the listener cannot see (or need to rewrite) an already-assembled `messages` array. The listener owns no threshold logic of its own (the single token-pressure check lives in `compactIfNeeded()`); because Cordis `serial` bails early on non-void return values, the listener returns `void` and does not use the dispatcher's bail channel as a veto surface. diff --git a/packages/compact/compact-basic/src/index.ts b/packages/compact/compact-basic/src/index.ts index 2bc7b65a80..d4a993471e 100644 --- a/packages/compact/compact-basic/src/index.ts +++ b/packages/compact/compact-basic/src/index.ts @@ -182,9 +182,9 @@ export class BasicCompactService extends CompactService { // log-only `compact/*` records and the replacement node cleanly outside a // step, so a crash mid-compaction leaves an inert orphan the turn-repair // closes — never a half-open step. - ctx.on('agent/pre-step', async (agent: Agent, turn: number, step: number, fullSystemPrompt: string, signal: AbortSignal) => { + ctx.on('agent/pre-step', async (agent: Agent, _turn: number, _step: number, fullSystemPrompt: string, signal: AbortSignal) => { try { - const result = await this.compactIfNeeded(agent, turn, step, fullSystemPrompt, signal) + const result = await this.compactIfNeeded(agent, fullSystemPrompt, signal) if (result) { const after = this.estimateTokens(agent.session.deriveMessages(), fullSystemPrompt) ctx.logger.info( @@ -271,9 +271,13 @@ export class BasicCompactService extends CompactService { } /** - * Summarize conversation text into content blocks via `agent/request` plus - * `ctx.llm.stream()` assembled through a `BlockAssembler` (the single - * model-call surface). + * Summarize conversation text into content blocks via `ctx.llm.stream()` + * assembled through a `BlockAssembler`.

This changes behavior for a synchronous step/start session/event listener that appends content (master derived after the append, so such a listener could reach the current request): agent/pre-step is the sanctioned seam for current-request content. - agent/request is re-typed to config-only: (agent, turn, step, config: LlmCallConfig, next) → LlmCallConfig. The frozen seed comes from AgentOptions on a loop instance's first request (explicit options beat the logged baseline — fork overrides and resume reconfiguration stay correct) and from the log's folded header afterwards; listeners return a replacement to switch. Content shaping through the request is no longer expressible — model-visible content flows through the log channels. - recordRequestHeader appends whatever header event the request owes the log before dispatch: an 'initial'/'resume' snapshot anchoring each loop instance, a round-trip-verified delta on change, a 'fallback' snapshot when the encoding cannot express it. Session.requestHeader() is the log's incrementally-folded baseline. - Requests are deep-frozen before dispatch (deepFreeze exempts the AbortSignal — freezing one breaks AbortController.abort() outright); frozen + sessionId is the loop-built marker the dev invariant keys on. Ported from #162 and re-anchored on the log: the append-extension / frozen-end-to-end / compaction-resend / prompt-change property tests, plus new specs for the boundary semantics, resume anchoring, and the end-to-end theorem (every recorded request rebuilds byte-equal from the log alone). Live cache-hit e2e (request-cache.e2e.ts) verified against the real DeepSeek API. Snapshot goldens intentionally stale until the single re-record after the compact/summary envelope lands. --- docs/cordis-catalog/events.md | 20 +- docs/cordis-catalog/services.md | 2 +- docs/event-producer-consumer.md | 14 +- packages/core/agent-loop/README.md | 8 +- packages/core/agent-loop/src/loop.ts | 109 +++++-- packages/core/agent-loop/src/request-log.ts | 68 +++++ packages/core/agent-loop/tests/loop.spec.ts | 20 +- .../agent-loop/tests/request-cache.e2e.ts | 104 +++++++ .../core/agent-loop/tests/request-log.spec.ts | 85 ++++++ .../tests/request-reconstruction.spec.ts | 284 ++++++++++++++++++ .../agent-loop/tests/review-fixes.spec.ts | 5 +- packages/core/agent/src/types.ts | 26 +- packages/core/session/src/index.ts | 26 +- packages/core/session/src/request-header.ts | 23 +- packages/llm/llm/src/call-config.ts | 6 +- packages/llm/llm/tests/call-config.spec.ts | 12 + scripts/gen-cordis-catalog.ts | 1 + 17 files changed, 745 insertions(+), 68 deletions(-) create mode 100644 packages/core/agent-loop/src/request-log.ts create mode 100644 packages/core/agent-loop/tests/request-cache.e2e.ts create mode 100644 packages/core/agent-loop/tests/request-log.spec.ts create mode 100644 packages/core/agent-loop/tests/request-reconstruction.spec.ts diff --git a/docs/cordis-catalog/events.md b/docs/cordis-catalog/events.md index 91425e9e2b..c34143bada 100644 --- a/docs/cordis-catalog/events.md +++ b/docs/cordis-catalog/events.md @@ -47,7 +47,7 @@ A step or turn errored.

text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The reconstructability RFC is the principle's home: model-visible ⟺ logged in both forms, the mechanism (boundary derivation + header fold), the enforcement (write-time round-trip guard, the dev invariant), the corollaries ranked (prefix-cache stability first), the MiniCode lineage with the provenance arrow inverted, and the alternatives it beat — including the stateful transmission client whose three-design archaeology lives in PR #162. Placements per the one-home-per-fact taxonomy: a standing-order line in root AGENTS.md (with displacement trims to stay inside the 1,575-word ceiling), the principle statement in architecture.md § Session Log and its Turn Flow lines (condensed to the ratcheted 1,630 ceiling), the request-envelope section in core-data-structures/core.md with the LlmCallConfig paste, both review-requested FIXMEs (FIXME(call-config-shape) beside the type, FIXME(catalog-verbs) at the catalog's drift-gate note), cookbook rows redirected off agent/request (tool filtering → system-prompt/assemble, plan-mode prompt → sections/ inject()), and the llm/stream JSDoc stating the frozen-request contract.

First, provider KV caching (DeepSeek context caching) is prefix-based — a request pays full price only for the tokens after the longest stored prefix it matches — yet nothing in the request pipeline stated, checked, or measured prefix stability: every registered [`PromptSection`](../../../../packages/core/system-prompt/src/index.ts) happened to be static, the tool set happened not to change mid-session, no listener happened to rewrite requests. A single time-interpolating section would have silently multiplied context cost, and no test or metric would have moved. Second, and deeper: the session log — the system's single source of truth — could not actually answer *what the model saw*. It recorded every message but never the system prompt, the tool schemas, or even which model; the mutable `agent/request` waterfall handed listeners the whole `GenerateOptions` to rewrite per call; replay equivalence was therefore a property of the plugin population, not of the design. + +The reference shape for the happy path is MiniCode's `LLMClient`: a stateful conversation client, appended to — never rebuilt — as the conversation advances, resetting only when the system prompt, tool set, or compaction genuinely changes what the model must see. The design question this RFC answers is how to get that discipline without giving up event-sourcing. + +## Decision + +### The principle + +**Model-visible ⟺ logged.** Anything that reaches a model request must be recorded in the session log. The checkable consequence: **every conversation request the loop sends is a pure function of the session log** — anyone holding the log reconstructs it byte-for-byte. Scope, stated precisely: the guarantee covers the loop-built `GenerateOptions`; provider wire bytes follow from it because both adapters' serialization is a pure per-message function at a pinned code version; direct one-shots (compaction's summarize call) log their envelope scalars (`compact/summary.{model, maxTokens}`) and their input is deterministic code over the logged region — reconstructable from log + code, outside the invariant by the unfrozen-request marker. + +Prefix-cache stability is corollary #1, not the headline: an append-only log projected by a per-node pure function yields requests that are append-extensions of their predecessors whenever the header is unchanged — stability is emergent, not managed. Byte-exact audit/replay is corollary #2; resume and fork with *attributable* drift is corollary #3. + +### The mechanism + +**Messages.** `Session.deriveMessages()` is cached: each surface node is projected exactly once, when first seen, through the public per-node function `deriveEventMessage(event)`; a surface rewrite (a compaction `replace` — `SurfaceManager.replaceGeneration`) rebuilds. Callers get a fresh array per call over shared, deep-frozen messages: mutating logged history through a projection is unrepresentable (it throws), replacing the old clone-per-call isolation. External reconstructors fold the same public function over a log prefix, so no two paths can disagree. + +**The header.** The request's non-content half — `EpochHeader`: call config (`LlmCallConfig`: model + sampling scalars), rendered system prompt, assembled tool schemas — is logged session state, in canonical form (empty system/tools ≡ absent). Two log-only, turn-enclosed events in dsh-session carry it: `request/header`, a full snapshot with reason `'initial' | 'resume' | 'fallback'`, and `request/header-delta`, an amendment (`SystemDelta`: a common-prefix/suffix line trim; `ToolsDelta`: name-keyed added/removed/changed; `config`: replaced whole). The pure trio `foldRequestHeader` / `diffHeader` / `applyHeaderDelta` reconstructs; the live session tracks the fold with the same lazy cursor as the message cache. Snapshots anchor the fold where a fold needs anchors — conversation birth and process boundaries — and each loop instance appends one on its first request (`'initial'` when the log has none, `'resume'` otherwise, even when nothing changed: the boundary itself is a recorded fact, and cross-restart drift becomes attributable while an unchanged header resumes byte-identical). Deltas are an encoding optimization with a safety valve, never a correctness dependency: the writer verifies `applyHeaderDelta(prev, delta)` reproduces the new header exactly and records a `'fallback'` snapshot when the encoding cannot express a change (a pure tool reordering), so a well-formed log always folds. + +**The loop, transmission-stateless.** Per step: render assembly (every step — value comparison needs no change-signal discipline, and a section that varies per step surfaces as a *logged* header event per step instead of a silent bust) → `agent/pre-step` (compaction's surface mutations land before derivation) → **messages snapshot, then `step/start` appended as the next operation in the same synchronous frame** → seed the call config (first request of the instance: from `AgentOptions`, so explicit options always beat the logged baseline — fork model-overrides and resume reconfiguration stay correct; afterwards: from the folded header) → the `agent/request` waterfall, re-typed `(agent, turn, step, config: LlmCallConfig, next) → LlmCallConfig` — a frozen seed and a returned replacement are ALL a listener shapes; content flows through the log channels (`inject()`, steering, prompt-submit `additionalContext`, sections via `system-prompt/assemble`) — → the header event the request owes the log → build `GenerateOptions` from the snapshot + header, deep-freeze (`deepFreeze` exempts the `AbortSignal`, the one live control channel — freezing one breaks `AbortController.abort()`), dispatch. The loop's only in-process bookkeeping is one boolean: whether this instance has logged its anchoring snapshot. + +**The reconstruction boundary is `step/start`, unconditionally.** A step's messages are the derivation over `events[0..stepStartSeq)`. Because the snapshot precedes the `step/start` append in the same synchronous frame, nothing can enter this request past the boundary: an `agent.inject()` from an `agent/request` listener (or any concurrent task, or a `session/event` listener firing on `step/start` itself) lands in the log after the boundary and joins the NEXT request. For waterfall-window appends this matches the prior loop (it also derived before its waterfall); for a synchronous `step/start` listener it is a deliberate change — such a listener could previously reach the current request — and `agent/pre-step` is the sanctioned seam for content that must affect the CURRENT request. A step's header for reconstruction is the fold after its own `request/header*` event (which sits between its `step/start` and first response event) or the fold carried forward. + +**Enforcement.** Dev-mode ([dsh-invariants](../../../../packages/support/invariants/src/index.ts)), on `llm/stream`: a frozen request with a live `sessionId` — the loop-built marker; hand-built one-shots are unfrozen and skipped — must carry messages deep-equal to the boundary derivation, rebuilt through a FRESH `Session` over `events[0..stepStartSeq)` so the live cache cannot vouch for itself, and header fields equal to `foldRequestHeader` over the log. There is no divergence allowance and nothing to allow: no seam can put unlogged content into a request. `prepend: true` only defends against the replay adapter's short-circuit (an append-registered listener); two prepended listeners have no defined mutual order in cordis, so correctness rests on the seq-bounded fold, never on listener timing. Measurement stays lean: the with-key e2e ([request-cache.e2e.ts](../../../../packages/core/agent-loop/tests/request-cache.e2e.ts)) proves `usage.cacheReadTokens > 0` on every request after the first against the live API, and per-step usage in the log is the production observable — a header event or compaction shows up as a cache-read collapse on the next step. + +### The MiniCode shape: adopted, with the provenance arrow inverted + +What survives from `LLMClient`: the conversation is maintained, not rebuilt — one projection per message, ever; requests advance append-only; resets happen only for a system-prompt/tool change, a config change, or compaction, each now a *logged* fact. What is deliberately inverted: MiniCode's client is the source of truth and its event stream derives from client appends (`on_event(MessageAdded)`), which suits an advisory event stream. Here the log is contractual — persistence, crash recovery, fork seeding, transcript rendering, and the snapshot harness all replay it — and it carries strictly more than a message list (turn/step boundaries, raw chunk streams, tool-call pairing, provenance, log-only records), so a message-list client cannot generate it. The arrow therefore points log → client: the conversation state IS the log plus two cached folds inside `Session` (messages, header), and the "client" the loop talks to is the session itself. What the inversion buys over the original: the reconstruction is *checkable* against an independent record on every request — MiniCode's client has nothing to check itself against. + +## Alternatives considered + +- **Client as source of truth** (literal MiniCode): a second operative truth beside the log — the two drift and nothing notices; see the section above. +- **A stateful transmission client mirroring the log** (a `PromptPrefix` class holding committed/open message zones with an append/editTail/reset vocabulary, the log pushed into it per event): behaviorally equivalent on the happy path, but it duplicates conversation state outside the session, needs transactional rollback around listener seams, keeps an unlogged content-shaping surface (`editTail`) whose divergence the invariant must specially allow, and still cannot answer "what header did the model see" from the log. Dissolving it into the session's own caches plus logged header events made every one of those problems unrepresentable instead of guarded. (PR #162 is the archaeology of this alternative, three designs deep.) +- **Per-call request scalars** (a freely mutable config handed to each `agent/request` dispatch): a listener flips the model per call with zero accounting, silently abandoning the provider cache this design exists to protect. Config is per-conversation logged state; the waterfall proposes, the log records. +- **Detect-and-report** (compare consecutive requests, warn on divergence): catches violations after the fact; a violating request is still constructible and ships. Rejected for interface-level unrepresentability. +- **Event-driven assembly** (re-render only on change signals): a missed-signal bug class — a tool registered mid-session emits `tools/change`, not `system-prompt/change`, and a third-party provider may emit nothing. Per-step render + value compare is robust with zero signal discipline. +- **Narrative fields on the header events** (a `reason`/`changed` list on deltas): derivable by diffing consecutive events — one home per fact; snapshots carry a reason because an anchor's cause is NOT derivable from the data. + +## Consequences + +- A request that is not explained by the log cannot be constructed by accident — not by the loop, not by a listener; mutating a built request throws; every header change is a durable, diffable log event. +- What still costs full price at the provider is inherent and logged: compaction (its `compact/*` events and replace node), a real prompt/tool change (`request/header-delta`), a config switch (ditto), a process boundary with drift (`'resume'` snapshot differing from its predecessor). The provider's own reasoning-content exclusion is managed server-side. +- The `step/start`-listener behavior change (above) is the one observable semantics change for plugins; `agent/pre-step` is the current-request seam. +- Tool-result trimming (planned) needs no new mechanism: a logged single-node surface replace (`start === end`) carrying a trimmed `tool/result` under the same `callId` — compaction-family, replay-correct, cache-bust batched by the same pressure logic. +- Session logs grow one `request/header` snapshot per conversation (system + tool schemas: the dominant term), plus deltas on real changes — small next to `assistant/chunk` volume; `SESSION_FORMAT_VERSION` stays `0` (pre-release churn is absorbed, backends reject-not-migrate). +- Snapshot goldens changed once (every transcript gains its header events); the fs-writing fixtures are stored in the normalized authored form with cwd-relative tool arguments, because replay only round-trips cwd-independent argument paths. +- FIXME(call-config-shape): revisit `LlmCallConfig`'s exact field set — which fields are genuinely epoch-level for cache purposes (`model` certainly; the sampling scalars sit there out of caution), and where provider-specific extras (reasoning options, extra body params) belong when an adapter needs them. diff --git a/packages/llm/llm/src/index.ts b/packages/llm/llm/src/index.ts index a55722c53c..0bab45e1bb 100644 --- a/packages/llm/llm/src/index.ts +++ b/packages/llm/llm/src/index.ts @@ -26,10 +26,14 @@ declare module 'cordis' { interface Events { /** - * Waterfall around every streaming model call (retry, caching, routing). + * Waterfall around every streaming model call (retry, replay, routing). * Bound to the {@link LlmService}; call `next()` to reach the resolved * adapter's stream, or yield your own chunks to short-circuit. - * @param options - the full request; listeners may rewrite it before delegating. + * @param options - the full request.

Subagents use a named provider registry because multiple delegation backends can coexist; `spawn` starts fresh, `fork` seeds from the parent's completed-turn prefix, and ACP can drive an out-of-process child ([subagent.md](core-data-structures/subagent.md)). ### Bundles And Apps @@ -144,6 +143,6 @@ New behavior should attach to a documented seam; changing the shipped loop requi | Intercept prompts, requests, tool use, or continuation | listen on the relevant `agent/*` or `tools/*` waterfall | | Add UI or editor integration | drive `ctx.agents` and render from `session/event` | | Add durable session state | add a `SessionEventMap` member and render/replay from the log | -| Fork a live session | use `ctx.sessionFork` to validate the boundary and create a seeded child session | +| Fork a live session | use `ctx.sessions.snapshot()` for reusable seed metadata or `ctx.sessions.fork()` to create a seeded child session | The [extension cookbook](cookbook/extension-cookbook.md) carries plugin skeletons and the feature-to-seam map; step-by-step guides cover [packages](cookbook/adding-a-package.md), [tools](cookbook/adding-a-tool.md), [LLM adapters](cookbook/adding-an-llm-adapter.md), and [vendored packages](cookbook/adding-a-vendored-package.md). diff --git a/docs/cordis-catalog/services.md b/docs/cordis-catalog/services.md index ac89ccc970..eaeca95539 100644 --- a/docs/cordis-catalog/services.md +++ b/docs/cordis-catalog/services.md @@ -126,17 +126,6 @@ Types: [GenerateOptions](../core-data-structures/core.md) · [StreamChunk](../co Source: [`packages/llm/llm/src/index.ts:78`](../../packages/llm/llm/src/index.ts) -## `ctx.sessionFork` — `SessionForkService` - -`ctx.sessionFork`: validates live session fork boundaries and creates seeded child sessions using the existing `ctx.sessions.create({ seed })` primitive. - -```ts cordis-catalog -snapshot(source: SessionForkSource): SessionForkSeed -fork(options: ForkSessionOptions): Session -``` - -Source: [`packages/session-fork/session-fork/src/index.ts:65`](../../packages/session-fork/session-fork/src/index.ts) - ## `ctx.sessionPersistence` — `SessionPersistence` (abstract seam) Abstract durable session-persistence service.

This keeps the fork computation reusable for future ACP or agent-facing consumers without coupling `dsh-session` to `ctx.agents`. - -`fork()` is the convenience half. It calls `snapshot()`, then creates a live child session via `ctx.sessions.create(sessionId, { seed, meta })`. The child inherits the source session's `cwd`, stamps `parentSession` to the source id, and sets `seedLength` to the seeded prefix length. When `sessionId` is omitted, `SessionStore` generates one using its existing id policy. - -The boundary rule is structural: an empty source log is forkable, and any source whose last event is `turn/end` is forkable regardless of the turn-end reason (`completed`, `aborted`, `error`, `disposed`, `max-tokens`, `interrupted`, or a future merge-extensible reason). Any non-empty source whose last event is not `turn/end` is inside a turn or otherwise not at the boundary and is rejected with a typed `SessionForkError` code. The helpers also classify non-live source ids (`SESSION_NOT_FOUND`), stale `Session` object references whose id is live on a different instance (`SESSION_NOT_LIVE`), and duplicate requested child ids (`SESSION_ALREADY_EXISTS`) instead of leaking lower-level store errors. - -## Alternatives considered - -**Separate `ctx.sessionFork` service.** This was the first implementation, but review showed it overfit the capability-seam pattern. The code had no swappable backend, no extra event surface, no independent ownership lifecycle, and no durable behavior beyond `ctx.sessions.create({ seed, meta })`. Keeping a separate package would make callers discover and install a second service just to perform policy around a session-store primitive. - -**Only expose `fork()`.** A one-function API is simpler for immediate child-session creation, but it forces callers that need a seed for another creation path to create a detached child session just to get the seed. `snapshot()` keeps the seed/metadata computation reusable without importing `ctx.agents` into `dsh-session`; `fork()` remains the simple one-call convenience. - -**Silently clip open turns to the last completed boundary.** That is correct for `dsh-subagent-fork`, where delegation often starts while the parent turn is open and the child should inherit only the completed prefix. It is wrong for ordinary user/session branching because it hides that the requested fork point was not actually a valid boundary and silently drops the parent turn tail. - -## Consequences - -The public surface stays small and discoverable: live session branching is part of `ctx.sessions`, next to `create({ seed })`, rather than a standalone service. Persistence continues to work through existing `session/created` and `session/flush` behavior: a forked child starts life with seeded events, so existing backends persist that seed once and preserve `parentSession` / `seedLength` in the header. - -The v1 scope still excludes ACP `session/fork`, unloaded persisted-session forking, model-facing tools, and subagent refactors. Those can consume `snapshot()` later. If a future ACP method is added, it should advertise the capability only after it has transcript/snapshot coverage; this RFC adds no editor-facing updates, so no ACP snapshot is required now. Fork-child replay remains covered by the existing [seed-boundary testing RFC](../../implemented/testing/2026-06-22-fork-child-replay-seed-boundary.md), while these helpers get focused `dsh-session` unit tests plus JSONL persistence coverage. diff --git a/packages/core/session/README.md b/packages/core/session/README.md index 6908c88dbd..7115b162cf 100644 --- a/packages/core/session/README.md +++ b/packages/core/session/README.md @@ -9,8 +9,7 @@ Creates and holds event-sourced `Session` instances.

The walk enforces per-field JSDoc prose on every pasted declaration and statically cross-checks the schemastery schema (z.object keys, z.intersect composition across packages): every schema-validated key must be a declared member of the config type. One violation existed repo-wide — the agents[].id field in dsh-agent-loop — fixed by adding its JSDoc (which shifts the cordis-catalog services page's source pointers; regenerated). verify-config-catalog (--check) joins doc-sync; doc-typecheck learns the ts config-catalog fence; gen-cordis-catalog exports its JSDoc/pointer helpers and LINK_MAP for reuse.

A deployment author assembling a config tree had to open every plugin's source (or trust its README) to learn what is settable. The per-package README `## Config` sections cover parts of it by hand, in formats that diverged package-by-package (a key/default table here, an annotated YAML snippet there) and with no gate tying them to source. Nothing enumerated which packages are loadable at all — plugin vs abstract seam vs plain library — and nothing verified that the runtime schemastery schema and the documented `Config` interface agree, so a schema-validated field could exist with no documentation anywhere. + +## Decision + +Generate the catalog from source: `scripts/gen-config-catalog.ts` emits [docs/config-catalog.md](../../../config-catalog.md), one section per configurable package containing the VERBATIM config declaration — the `export interface Config` (or equivalently named type) with its JSDoc, pasted as-is in a ` ```ts config-catalog ` fence — plus a `Requires:` line (the plugin's `inject`), a `Depends on:` line resolving every type name the paste references, and a source pointer. Package-local referenced types are pasted transitively into the same fence; another plugin's config type links to that plugin's section; names in the cordis catalog's shared `LINK_MAP` link to core-data-structures; any other workspace type links to its source; an external type is named with its module. It mirrors the `gen-cordis-catalog` pattern exactly: `--write` regenerates, `--check` (`verify-config-catalog`, inside `doc-sync`) fails if the committed file is stale, output is deterministic, the file is a build artifact never hand-edited. + +Pure AST generation is correct here for the same reason it is for the events/services catalog and NOT for the tool catalog: a config type is a static declaration and every schemastery schema in the repo is a static `z.object`/`z.intersect` literal, so the source is the whole truth — nothing about the config surface is runtime-composed. + +Specific choices: + +- **The config type is the second-parameter type.** What the catalog documents is the declared type of `apply(ctx, config)` / the service constructor's `(ctx, config)` — the value cordis actually passes — not a `Config` export located by naming convention. This is what makes the walk total: it works for interfaces named `AcpConfig` or `BasicCompactConfig`, for types declared in a sibling file, and for plugins with no validating schema at all. +- **Classification is total.** Every `packages//` entry resolves, mirroring the Loader's `unwrapExports` (`exports.default ?? exports`), to a configurable plugin, a config-free plugin, an abstract seam class, or a library — each rendered in its own section — and an unclassifiable entry hard-errors. A new package cannot be silently undocumented. +- **Per-field JSDoc is enforced.** Every property of a pasted declaration (nested type literals included) needs non-empty JSDoc prose, or generation fails. The paste IS the documentation, so this is the same forcing function the events catalog applies via `@mode`: thin source docs fail the gate rather than yielding a thin catalog. +- **The schema is cross-checked, one-directionally.** When a plugin declares a schemastery schema (`export const Config` / `static Config`), the generator walks it statically — object-literal keys, chained refinements, and `z.intersect` composition across workspace packages — and every schema-validated top-level key must be a declared member of the config type, so the paste cannot hide a loader-accepted field. The reverse is deliberately unchecked: a declared field may be a runtime-only seam the schema excludes (the ACP bridge's test-injected `stream`). +- **A dedicated fence.** Pasted declarations use a ` ```ts config-catalog ` info string that `doc-typecheck` skips (a lone declaration referencing imported types is not standalone-compilable), excluded from the opt-out ratio — the same treatment the `cordis-catalog` and `persistence-catalog` fences get. +- **A single file at `docs/config-catalog.md`**, not a one-file directory: the page serves one audience (the `cordis.yml` author) with one axis, unlike `cordis-catalog/`, which holds two sibling pages. + +The package README `## Config` sections stay. The overlap is accepted deliberately: the README is the curated per-package contract (config semantics in deployment context, alongside limitations and extension points), the catalog is the exhaustive generated enumeration. Because the catalog is generated, a disagreement between the two indicts the README, and the fix is a README edit — the catalog cannot drift. + +## Alternatives considered + +- **Synthesized per-field rendering** — a bullet list, table, or annotated-YAML snippet per field, assembled from parsed JSDoc plus schema metadata. Rejected for the verbatim paste: the interface with its JSDoc is already the authored contract in its authored form, and a synthesizing renderer re-formats prose it does not own, adding a rendering layer that can misrepresent it. +- **Runtime boot + schema introspection, as the tool catalog does** — rejected: nothing here is runtime-composed, and the schema alone under-documents the surface (prose-documented defaults, runtime-only fields, plugins with no schema at all). Booting would add fragility without adding truth. +- **Two-directional schema/interface equality** — rejected for the subset check: the declared type legitimately carries members the schema refuses to accept from config (runtime-only seams). +- **Retiring the README `## Config` sections in the same change** — rejected: the accepted duplication keeps the per-package contract readable in place, and a sweep would have to fold each README's extra facts into field JSDoc first — separable work the catalog does not depend on. + +## Consequences + +- The catalog cannot drift: a source change the committed file does not reflect fails `verify-config-catalog` in pre-push and CI. An undocumented config field, an unresolvable referenced type name, or a schema key missing from the config type fails the generator outright. +- Config prose now has a forcing function at the declaration: writing a new config field means writing its JSDoc, which becomes the catalog entry verbatim. +- The generator hard-errors on shapes it cannot walk statically — an aliased package-local config import, a schema built by anything other than `object`/`intersect` composition, an unlisted global type name. Introducing such a shape includes teaching the generator (or the shape stays out of the repo), which is the point: the catalog stays the whole truth. +- `gen-cordis-catalog.ts` exports its JSDoc/pointer helpers and `LINK_MAP` for reuse, so the two catalogs cross-link types identically and a link-map addition serves both. diff --git a/package.json b/package.json index 7453a022e9..0791565ae1 100644 --- a/package.json +++ b/package.json @@ -41,6 +41,8 @@ "verify-cordis-catalog": "tsx scripts/gen-cordis-catalog.ts --check", "gen-tool-catalog": "tsx scripts/gen-tool-catalog.ts", "verify-tool-catalog": "tsx scripts/gen-tool-catalog.ts --check", + "gen-config-catalog": "tsx scripts/gen-config-catalog.ts", + "verify-config-catalog": "tsx scripts/gen-config-catalog.ts --check", "gen-doc-graphs": "tsx scripts/gen-doc-graphs.ts", "verify-doc-graphs": "tsx scripts/gen-doc-graphs.ts --check", "gen-persistence-catalog": "tsx scripts/gen-persistence-catalog.ts", @@ -48,7 +50,7 @@ "gen-module-graph": "tsx scripts/gen-module-graph.ts", "verify-module-graph": "tsx scripts/gen-module-graph.ts --check", "constraints": "tsx scripts/check-workspace-constraints.ts", - "doc-sync": "pnpm run doc-typecheck && pnpm run verify-cordis-catalog && pnpm run verify-tool-catalog && pnpm run verify-persistence-catalog && pnpm run verify-doc-graphs && pnpm run verify-md-wrap && pnpm run verify-md-links && pnpm run verify-doc-refs && pnpm run verify-package-paths && pnpm run verify-mermaid && pnpm run verify-rfc-classification && pnpm run verify-rfc-format && pnpm run verify-type-equiv && pnpm run verify-translation-pairing && pnpm run verify-doc-budgets", + "doc-sync": "pnpm run doc-typecheck && pnpm run verify-cordis-catalog && pnpm run verify-tool-catalog && pnpm run verify-config-catalog && pnpm run verify-persistence-catalog && pnpm run verify-doc-graphs && pnpm run verify-md-wrap && pnpm run verify-md-links && pnpm run verify-doc-refs && pnpm run verify-package-paths && pnpm run verify-mermaid && pnpm run verify-rfc-classification && pnpm run verify-rfc-format && pnpm run verify-type-equiv && pnpm run verify-translation-pairing && pnpm run verify-doc-budgets", "hygiene": "pnpm run knip && pnpm run publint && pnpm run constraints && pnpm run verify-node-next-types", "demo:echo": "node --expose-internals --import tsx packages/ui/stdio-agent/src/bin.ts examples/echo-agent/cordis.yml", "demo:repl": "node --expose-internals --import tsx packages/ui/stdio-agent/src/bin.ts examples/coding-agent/cordis.yml", diff --git a/packages/core/agent-core/tests/gen-config-catalog.spec.ts b/packages/core/agent-core/tests/gen-config-catalog.spec.ts new file mode 100644 index 0000000000..0db1b30c9e --- /dev/null +++ b/packages/core/agent-core/tests/gen-config-catalog.spec.ts @@ -0,0 +1,318 @@ +/** + * Negative-path tests for the config catalog generator (`scripts/gen-config-catalog.ts`). + * + * The generated catalog is frozen by a regenerate-and-diff freshness gate, so + * the freshness half is exercised by `pnpm run verify-config-catalog` in CI. + * What a freshness diff CANNOT prove is that the generator REJECTS malformed + * source the way it promises to — an unclassifiable package, an undocumented + * config field, a schema key the config type does not declare, or a referenced + * type name that resolves nowhere.

The parsing + check helpers move out of gen-cordis-catalog.ts into a shared scripts/jsdoc.ts so 'documented' means one thing on both gated surfaces. Deliberate exemptions (documented in the RFC): heritage-declared class members (the seam declaration is the doc's one home — the one checker query in an otherwise pure-AST walk), cordis plugin-protocol slots (name/inject/reusable/Config/apply, top-level and static), constructors, overload implementations, declare-module augmentation bodies, and re-export statements (checked at the defining module). The 203 under-documented exports the gate found at adoption are filled in this change, so the gate lands green; generated catalogs/graphs are regenerated for the shifted line pointers.

Every module has a module-level doc comment; every export (and non-obvious method) has a JSDoc explaining semantics — contracts, disposal, errors — not the name restated; internal helpers only where non-obvious; one-liners when one line suffices. The export half is mechanical: `verify-export-jsdoc` (in `doc-sync`) requires description prose on every package export plus `@param`/`@returns` (and an annotated return) on function-like ones — heritage-declared members, plugin-protocol slots, and constructors exempt ([export-gate RFC](docs/rfc/implemented/process/2026-07-06-export-surface-jsdoc-gate.md)). Lean toward the stricter lint rule and the extra mechanical gate: encode invariants in checks (`verify-*` scripts), preferring a narrow justified escape hatch over a rule left off globally. Type gymnastics are acceptable inside core packages when they buy plugin-author DX (the `defineTool` schema DSL is the canonical example). Docs are part of every change: code changes update their README and JSDoc in the SAME change; a bilingual-pair edit updates the counterpart and re-records ([i18n contract](docs/i18n/README.md)).

The AGENTS.md rule "every export (and non-obvious method) has a JSDoc explaining semantics" stayed prose-checkable only by review everywhere else, and nothing at all asked for `@param`/`@returns` on ordinary exported functions. A survey at adoption found 203 under-documented module-level exports across 34 packages: seam-adjacent helpers (`runBash`, `readForEdit`, `htmlToMarkdown`), format codecs, whole undocumented interfaces and type aliases — exactly the names an IDE consumer hovers. + +## Decision + +A new gate, `scripts/verify-export-jsdoc.ts` (`pnpm run verify-export-jsdoc`, wired into `doc-sync` beside `verify-cordis-catalog`), walks every module-level exported name under each `packages///src/` tree. The parsing and check helpers moved from `gen-cordis-catalog.ts` into a shared `scripts/jsdoc.ts`, so "documented" means the same thing on both surfaces: description prose ends at the first block tag, every checkable parameter needs a non-empty `@param`, a non-void ANNOTATED return needs a non-empty `@returns`, a stale `@param` errors, and violations aggregate into one report. + +The contract by declaration kind: + +- Every exported name needs JSDoc with non-empty description prose. +- Function-like exports (function declarations; consts with function initializers) follow the full function contract. A const whose declarator is type-annotated (`export const f: Handler = …`) defers the return contract to the named type; `@returns` stays optional there. +- Exported classes need class-level prose; public methods (statics included — reachable on the exported name) follow the function contract; public properties and accessors need prose (a get/set pair is covered by the getter). Overload implementations are exempt — the signatures carry the docs. +- Exported interfaces, type aliases, and enums need prose on the declaration; member-level enforcement is deliberately deferred (the highest-value member surface — seam service classes — is already under the cordis gate). +- Exported namespaces recurse; the namespace itself needs prose only when it does not merge with a documented same-name declaration (the Config-namespace idiom documents the plugin once). +- `declare module` / `declare global` bodies and `export … from` re-export statements are skipped: an augmentation is not an export of the package, and a re-exported definition is checked where it is defined. + +Three exemption families keep the gate from demanding boilerplate, in the spirit of the cordis gate's `this`/`next` exemptions (documenting an exempt name anyway is allowed; only absence goes unchecked): + +- **Heritage members.** A class member whose name exists on an `extends`/`implements` heritage type is exempt: the seam declaration is the doc's one home, and the IDE inherits it on hover — re-documenting every `LocalBashExecutor.run` invites drift. This is the one question the walk asks the TYPE CHECKER (heritage types live across package boundaries, resolved through the repo `paths` map); everything else stays pure AST, and the annotated-return requirement is kept for symmetry with the cordis gate (it bound nothing at adoption — every exported function was already annotated). +- **Plugin-protocol slots.** Top-level `name` / `inject` / `reusable` / `Config` consts and the `apply` entry, plus the same slots as statics on a plugin class, are framework protocol: their shape is fixed by cordis, and the module doc comment plus the `interface Config` carry the plugin's real semantics. +- **Constructors**, mirroring the cordis gate: plugin classes are framework-constructed, and the class doc owns the story. + +`collectExportJsdocViolations()` returns the violation list (the CLI exits 1 on non-empty) so the negative-path tests in `packages/core/agent/tests/verify-export-jsdoc.spec.ts` assert on findings directly, driving fixture packages through every rejection and every exemption. + +## Alternatives considered + +- **eslint-plugin-jsdoc** (`require-jsdoc`/`require-param`/`require-returns`) — covers the mechanical core but cannot express the repo's contract: the heritage-member exemption needs cross-package type resolution, the protocol-slot and namespace-merge idioms are cordis-specific, and the completeness semantics (prose-above-tags, stale-tag errors, aggregate reporting) already have one home in `scripts/jsdoc.ts` shared with the catalog generator. Two subtly different definitions of "documented" is the failure mode this repo's one-home rule exists to prevent. +- **Extending `gen-cordis-catalog.ts`** — the catalog generator renders a curated surface and gates its freshness; a repo-wide walk has no catalog to render. Sharing the helpers while keeping the walks separate keeps each gate's scope legible. +- **Enforcing interface/type-alias member docs** — deferred: it would multiply the checked surface for members that are largely self-describing fields, while the seam classes carrying the load-bearing member contracts are already gated. Revisit if member-doc drift shows up in review. + +## Consequences + +- A new export cannot land undocumented: `verify-export-jsdoc` fails `doc-sync`, which pre-push and CI already run. The 203 gaps found at adoption were filled in the same change, so the gate landed green. +- Exported functions must annotate return types (universal at adoption, now load-bearing) and use identifier parameters where `@param` must name them. +- Seam docs are canonical: an implementation inherits its heritage docs, and behavior notes worth keeping on the implementation are additions, not requirements. +- The gate builds a `ts.Program` (~6s) — the one doc gate that pays for type resolution; acceptable inside `doc-sync`, which already compiles doc snippets. +- The protocol-slot names are reserved by convention at module top level; a non-protocol export coincidentally named `apply` or `Config` would go unchecked — accepted, documented here. diff --git a/package.json b/package.json index 7453a022e9..662f381711 100644 --- a/package.json +++ b/package.json @@ -39,6 +39,7 @@ "gen-cordis-catalog": "tsx scripts/gen-cordis-catalog.ts", "gen-rfc-index": "tsx scripts/gen-rfc-index.ts", "verify-cordis-catalog": "tsx scripts/gen-cordis-catalog.ts --check", + "verify-export-jsdoc": "tsx scripts/verify-export-jsdoc.ts", "gen-tool-catalog": "tsx scripts/gen-tool-catalog.ts", "verify-tool-catalog": "tsx scripts/gen-tool-catalog.ts --check", "gen-doc-graphs": "tsx scripts/gen-doc-graphs.ts", @@ -48,7 +49,7 @@ "gen-module-graph": "tsx scripts/gen-module-graph.ts", "verify-module-graph": "tsx scripts/gen-module-graph.ts --check", "constraints": "tsx scripts/check-workspace-constraints.ts", - "doc-sync": "pnpm run doc-typecheck && pnpm run verify-cordis-catalog && pnpm run verify-tool-catalog && pnpm run verify-persistence-catalog && pnpm run verify-doc-graphs && pnpm run verify-md-wrap && pnpm run verify-md-links && pnpm run verify-doc-refs && pnpm run verify-package-paths && pnpm run verify-mermaid && pnpm run verify-rfc-classification && pnpm run verify-rfc-format && pnpm run verify-type-equiv && pnpm run verify-translation-pairing && pnpm run verify-doc-budgets", + "doc-sync": "pnpm run doc-typecheck && pnpm run verify-cordis-catalog && pnpm run verify-export-jsdoc && pnpm run verify-tool-catalog && pnpm run verify-persistence-catalog && pnpm run verify-doc-graphs && pnpm run verify-md-wrap && pnpm run verify-md-links && pnpm run verify-doc-refs && pnpm run verify-package-paths && pnpm run verify-mermaid && pnpm run verify-rfc-classification && pnpm run verify-rfc-format && pnpm run verify-type-equiv && pnpm run verify-translation-pairing && pnpm run verify-doc-budgets", "hygiene": "pnpm run knip && pnpm run publint && pnpm run constraints && pnpm run verify-node-next-types", "demo:echo": "node --expose-internals --import tsx packages/ui/stdio-agent/src/bin.ts examples/echo-agent/cordis.yml", "demo:repl": "node --expose-internals --import tsx packages/ui/stdio-agent/src/bin.ts examples/coding-agent/cordis.yml", diff --git a/packages/bash/bash-local/src/run.ts b/packages/bash/bash-local/src/run.ts index 489d380787..b39e45c5f5 100644 --- a/packages/bash/bash-local/src/run.ts +++ b/packages/bash/bash-local/src/run.ts @@ -56,6 +56,8 @@ export const SENSITIVE_ENV_PATTERN = /KEY|SECRET|TOKEN/i * by in-process plugins (the hooks bridges), not the model — `dsh-tool-bash` * builds its request from named fields only and does not forward model input * here (see its README, § "The tool builds its request from named args only"). + * @param extra - caller-supplied entries merged last; an explicit entry wins even against the scrub and the overrides. + * @returns the environment to hand to `spawn` for the child process. */ export function childEnv(extra?: Record): NodeJS.ProcessEnv { const env: NodeJS.ProcessEnv = {} @@ -147,6 +149,14 @@ export class OutputCollector { private readonly spillDir: string, ) {} + /** + * Ingest one stream chunk, counting it toward the whole-stream total.

The walk now collects nested object/array compositions as key paths and resolves each against the declared config type — through interfaces (heritage included), aliases, literals, intersections, unions, arrays, indexed access, Partial-style wrappers, and type references across package-local and workspace imports (re-export chains included). The check stays presence-only and one-directional, and only a definite miss is a violation: a path crossing a type the walk cannot enumerate (an external package's) is skipped, never mis-reported. The recursion guard applies at named declarations only — a structural first child shares its span start with its parent, so a span-keyed guard on every node mistakes ordinary descent for a cycle and silently turns definite misses into unknowns. The page and RFC framing also overstated the catalog as the exact cordis.yml-settable surface: the paste is the plugin's full declared config type, and a field the runtime schema deliberately excludes (the ACP bridge's test-injected stream) is a runtime-only seam its own JSDoc marks. Both now say so. Five spec cases pin the new behavior: nested hidden key, workspace intersection via star re-export, Partial wrapper, indexed-access composition, and the external-type unknown path. --- docs/config-catalog.md | 4 +- .../2026-07-06-generated-config-catalog.md | 4 +- .../tests/gen-config-catalog.spec.ts | 120 ++++++++ scripts/gen-config-catalog.ts | 287 ++++++++++++++++-- 4 files changed, 381 insertions(+), 34 deletions(-) diff --git a/docs/config-catalog.md b/docs/config-catalog.md index 4421b36851..1108727c30 100644 --- a/docs/config-catalog.md +++ b/docs/config-catalog.md @@ -3,9 +3,9 @@ # Plugin Config Catalog -Every `config:` block a `cordis.yml` entry can set: for each loadable harness package, the verbatim config declaration (JSDoc included) its `apply` function or service constructor receives, with every referenced type pasted alongside (package-local types) or linked (everything else).

This is what makes the walk total: it works for interfaces named `AcpConfig` or `BasicCompactConfig`, for types declared in a sibling file, and for plugins with no validating schema at all. - **Classification is total.** Every `packages//` entry resolves, mirroring the Loader's `unwrapExports` (`exports.default ?? exports`), to a configurable plugin, a config-free plugin, an abstract seam class, or a library — each rendered in its own section — and an unclassifiable entry hard-errors. A new package cannot be silently undocumented. - **Per-field JSDoc is enforced.** Every property of a pasted declaration (nested type literals included) needs non-empty JSDoc prose, or generation fails. The paste IS the documentation, so this is the same forcing function the events catalog applies via `@mode`: thin source docs fail the gate rather than yielding a thin catalog. -- **The schema is cross-checked, one-directionally.** When a plugin declares a schemastery schema (`export const Config` / `static Config`), the generator walks it statically — object-literal keys, chained refinements, and `z.intersect` composition across workspace packages — and every schema-validated top-level key must be a declared member of the config type, so the paste cannot hide a loader-accepted field.

So the paste cannot hide a loader-accepted field, top-level or nested. The check is presence-only and fails loud only on a definite miss: a path crossing a type the walk cannot enumerate (an external package's type) is skipped rather than mis-reported, and dynamic-key shapes (`z.dict`) or union alternatives contribute no nested paths. The reverse direction is deliberately unchecked: a declared field may be a runtime-only seam the schema excludes (the ACP bridge's test-injected `stream`). - **A dedicated fence.** Pasted declarations use a ` ```ts config-catalog ` info string that `doc-typecheck` skips (a lone declaration referencing imported types is not standalone-compilable), excluded from the opt-out ratio — the same treatment

Eight new negative-path tests pin the closed gaps; RFC and module doc updated to the refined contract. --- .../2026-07-06-export-surface-jsdoc-gate.md | 9 +- .../agent/tests/verify-export-jsdoc.spec.ts | 100 +++++++++ scripts/verify-export-jsdoc.ts | 193 +++++++++++++----- 3 files changed, 249 insertions(+), 53 deletions(-) diff --git a/docs/rfc/implemented/process/2026-07-06-export-surface-jsdoc-gate.md b/docs/rfc/implemented/process/2026-07-06-export-surface-jsdoc-gate.md index fa92fbcb3d..f3e6ab45c5 100644 --- a/docs/rfc/implemented/process/2026-07-06-export-surface-jsdoc-gate.md +++ b/docs/rfc/implemented/process/2026-07-06-export-surface-jsdoc-gate.md @@ -13,15 +13,16 @@ A new gate, `scripts/verify-export-jsdoc.ts` (`pnpm run verify-export-jsdoc`, wi The contract by declaration kind: - Every exported name needs JSDoc with non-empty description prose. -- Function-like exports (function declarations; consts with function initializers) follow the full function contract.

The floating continuation also made the coverage gate racy: the only coverage of the SubagentStart continuation's no-context branch arm rode on an un-awaited .then, and on a loaded CI runner the fork's per-file coverage snapshot beat it — master run 28798191671 failed the 100% branch gate on hooks-claude/src/index.ts at 99.03% (uncovered line 336) with the identical tree passing the PR run three minutes earlier. New shared primitive createDetachedRuns() in dsh-hook-protocol: a bridge tracks each detached run chain, passes the tracker's abort signal to runHook, and registers drain() as its effect disposer — drain aborts still-running hook processes (a kill via the bash seam, not a wait out to the 10-minute default hook timeout), then resolves once every chain has settled. fiber.dispose() resolving now means the bridge's detached work is quiescent (docs/defensive-patterns.md). The subagent marker test disposes the bridge as its sync point, so the formerly racy branch arm is executed deterministically before the file's coverage snapshot; new tests pin abort-on-dispose promptness for both bridges and the tracker's settle/drain contract in hook-protocol. --- packages/hooks/README.md | 2 +- packages/hooks/hook-protocol/README.md | 2 + packages/hooks/hook-protocol/src/detached.ts | 71 +++++++++++++++++++ packages/hooks/hook-protocol/src/index.ts | 4 ++ .../hook-protocol/tests/detached.spec.ts | 68 ++++++++++++++++++ packages/hooks/hooks-claude/README.md | 2 + packages/hooks/hooks-claude/src/index.ts | 22 ++++-- .../hooks/hooks-claude/tests/bridge.spec.ts | 53 +++++++++++--- packages/hooks/hooks-codex/README.md | 2 + packages/hooks/hooks-codex/src/index.ts | 11 ++- .../hooks/hooks-codex/tests/bridge.spec.ts | 42 ++++++++++- 11 files changed, 260 insertions(+), 19 deletions(-) create mode 100644 packages/hooks/hook-protocol/src/detached.ts create mode 100644 packages/hooks/hook-protocol/tests/detached.spec.ts diff --git a/packages/hooks/README.md b/packages/hooks/README.md index 2bdb65d5bf..b483964c32 100644 --- a/packages/hooks/README.md +++ b/packages/hooks/README.md @@ -4,7 +4,7 @@ The hooks subsystem lets users extend the agent at lifecycle points the way Clau | Package | Role | Shape | |---|---|---| -| `hook-protocol/` | Shared wire-protocol core: matcher primitive, exit-code/stdout codec, `runHook` (via `ctx.bash`), most-restrictive merge, `hook/*` session events | library (no plugin) | +| `hook-protocol/` | Shared wire-protocol core: matcher primitive, exit-code/stdout codec, `runHook` (via `ctx.bash`), most-restrictive merge, `hook/*` session events, detached-run quiescence | library (no plugin) | | `hooks-claude/` | Bridge for a Claude Code `hooks.json` / settings | plugin | | `hooks-codex/` | Bridge for a Codex `hooks.json` | plugin | diff --git a/packages/hooks/hook-protocol/README.md b/packages/hooks/hook-protocol/README.md index 64ed64b000..8effe7a97a 100644 --- a/packages/hooks/hook-protocol/README.md +++ b/packages/hooks/hook-protocol/README.md @@ -13,6 +13,7 @@ Why a shared lib at all: Codex deliberately reimplements a *subset* of the Claud | Decode output | `parseHookOutput(exit, stdout, stderr)` → neutral `HookOutput` | maps the neutral `HookOutput` onto a seam-specific typed Decision | | Merge N hooks | `mergeHookOutputs(outputs)` → most-restrictive `MergedHookOutcome` | — | | Durable record | `appendHookInvoked` / `appendHookResult` (`hook/*` session events; the result's `decision`/`stderrSummary` derive from the `HookOutput` here) | calls them around each invocation | +| Detached-run quiescence | `createDetachedRuns()` — track fire-and-forget run chains; `drain()` aborts, then awaits them | passes `signal` to each detached `runHook`, registers `drain` as its effect disposer | ## Primitives @@ -20,6 +21,7 @@ Why a shared lib at all: Codex deliberately reimplements a *subset* of the Claud - **`runHook(bash, hook, options, now)`** — serialize `options.payload` to the hook's stdin (with a trailing newline iff `options.trailingNewline`), merge `options.env` after the executor's credential scrub (the `dsh-bash` trusted-plugin surface), honor the hook's `timeoutSec` (else `options.defaultTimeoutMs` — the bridge owns the default, its config defaulting to the lib's `DEFAULT_HOOK_TIMEOUT_MS` 10-minute reference), and decode the result (threading `options.expectedEventName` to the codec).

The schemas key the `hookSpecificOutput` block by `hookEventName`, so passing `expectedEventName` (the firing event) DISCARDS a block whose `hookEventName` names a different event — or omits it entirely — its event-scoped fields don't take effect (a `PreToolUse` block on a `Stop` hook is malformed, and so is a discriminator-less block that would otherwise apply to any event), while the event-agnostic top-level fields still apply.

Doing so deferred their apply past the todo plugin, and the delegation tool mirrors provider lifecycle — so the model-visible tool order of every existing prompt changed, invalidating every recorded snapshot fixture. The runtime now gates its capture-tool registration on tools availability itself (sync when live, a scoped inject fiber when the Loader starts the backend first), keeping this PR byte-invisible to existing transcripts: all 35 snapshot scenarios pass against master's fixtures unchanged. --- docs/cordis-catalog/events.md | 6 +- docs/cordis-catalog/services.md | 2 +- docs/core-data-structures/subagent.md | 4 +- docs/event-producer-consumer.md | 6 +- docs/module-graph.md | 4 +- packages/core/tools/README.md | 6 + packages/core/tools/src/index.ts | 10 + packages/core/tools/src/json-schema.ts | 322 ++++++++++++ packages/core/tools/tests/json-schema.spec.ts | 254 +++++++++ packages/subagent/subagent-fork/README.md | 3 +- packages/subagent/subagent-fork/src/index.ts | 37 +- .../tests/multi-subagent.spec.ts | 4 +- .../subagent-fork/tests/subagent-fork.spec.ts | 14 +- .../subagent/subagent-inprocess/README.md | 21 +- .../subagent/subagent-inprocess/package.json | 4 + .../subagent/subagent-inprocess/src/index.ts | 99 +++- .../subagent-inprocess/src/structured.ts | 239 +++++++++ .../tests/structured.spec.ts | 485 ++++++++++++++++++ .../tests/subagent-inprocess.spec.ts | 6 +- .../subagent/subagent-inprocess/tsconfig.json | 6 + packages/subagent/subagent-spawn/README.md | 5 +- packages/subagent/subagent-spawn/src/index.ts | 51 +- .../subagent/subagent-spawn/tests/harness.ts | 2 +- .../tests/subagent-spawn.spec.ts | 14 +- packages/subagent/subagent/src/types.ts | 14 +- .../subagent/subagent/tests/service.spec.ts | 4 +- .../subagent-mock/tests/subagent-mock.spec.ts | 4 +- pnpm-lock.yaml | 6 + 28 files changed, 1570 insertions(+), 62 deletions(-) create mode 100644 packages/core/tools/src/json-schema.ts create mode 100644 packages/core/tools/tests/json-schema.spec.ts create mode 100644 packages/subagent/subagent-inprocess/src/structured.ts create mode 100644 packages/subagent/subagent-inprocess/tests/structured.spec.ts diff --git a/docs/cordis-catalog/events.md b/docs/cordis-catalog/events.md index 753cf8f4d0..0f7ed1dc68 100644 --- a/docs/cordis-catalog/events.md +++ b/docs/cordis-catalog/events.md @@ -307,7 +307,7 @@ A tool was registered or unregistered (the available tool set changed).

Registration order is plugin load order, and plugin load order is a race: the cordis loader imports every `cordis.yml` entry concurrently, so which tool plugin registers first depends on module-import completion timing. The plugin dependency relation cannot rescue this — it is a partial order under which independent tool plugins (e.g. `tool-subagent` vs `tool-todo`) are incomparable, so both interleavings are legal linearizations. This stopped being theoretical when a CI runner resolved the race differently from every recording machine: snapshot goldens pinned one permutation of `request/header.tools`, the `node 22.18` CI leg produced the other, and 5/5 snapshot tests failed on a diff that was pure array reordering.

The list must contain `'...'` exactly once and no duplicate names — violations throw from the service constructor, failing the fiber at load, never mid-conversation.

Everything downstream inherits the order untouched: the waterfall, the loop's `EpochHeader`, the `request/header` event, the deep-frozen request, and the dev invariant's cross-check all see one deterministic list, with no new service surface and no loop change. + +Scope is deliberately narrow: this fixes the REGISTRATION-ORDER race, not plugin behavior. A `system-prompt/assemble` listener may still add, remove, or rearrange tools — same as it may edit sections after their sort — and owns the determinism of what it emits; the waterfall contract already demands deterministic listeners (the reconstructability invariant would catch a listener that diverges between build and replay). + +Config plumbing follows the `persona` precedent, and `toolOrder` sits beside it: the app configs (`dsh-stdio-agent`, `dsh-acp-agent`) accept the key and forward it through `dsh-agent-core` (whose schema is the intersection of the owners' schemas) to the `SystemPrompt` child. One schemastery footnote is load-bearing: a schemastery array defaults to `[]`, but an omitted `toolOrder` must stay ABSENT (= lexicographic) rather than become an explicitly-configured empty list (invalid — it lacks `'...'`), so every schema on the chain forces the default to `undefined`. + +## Alternatives considered + +- **Registration order (the status quo)** — a concurrent-import race, host-dependent (the CI flake above), invisible in review. +- **A linearization of the plugin dependency graph** — the relation is partial and independent tool plugins are incomparable; the flake happened with the partial order fully satisfied. +- **Per-plugin `weight` on each tool contribution** — scatters the order across plugins yet still needs a global numbering convention nobody owns (the section `order` bands show that coordination cost being paid by hand). +- **Sorting in `ToolRegistry.schemas()` (the registry layer)** — equally deterministic, but the registry is a membership store consumed by more than the assembly; ordering is a prompt-composition concern, and the assembly already owns the composition policy for sections. +- **A `LlmService` config + `orderTools()` method the loop calls before logging the header** — works, but adds a public service method and a loop edit solely to apply a policy at a distance; every future request composer must remember the call. Canonicalizing where the list is born makes an unordered list unrepresentable, with zero new surface. +- **Normalizing inside `llm.stream()`** — runs after the header event is logged (the flake survives) and rebuilds the deep-frozen envelope, silently disarming the reconstruction invariant. +- **An exhaustive list (no `'...'` rest entry)** — every newly loaded tool plugin would break boot; the mandatory rest entry keeps unlisted tools deterministic and their position explicit. + +## Consequences + +- Every assembly — and therefore every `request/header` event and model request — has a deterministic tool order on every host; the CI-vs-local golden flip is structurally gone. The default order is lexicographic, no longer registration order. +- `PromptAssembly.tools` itself is canonical, so every assembly consumer (the loop, waterfall listeners, any future prompt inspector) sees the model-facing order; provider registration order is observable nowhere downstream of the registry. +- Snapshot fixtures and goldens were re-recorded (the `request/header.tools` segments changed); the authored, never-re-recorded scenarios (`cancel`, `error-finish`) had their fixture headers reordered by hand. +- A pure tool reordering between steps is representable only as a `request/header` `'fallback'` snapshot (the name-keyed `ToolsDelta` cannot express it); with a stable canonical order such reorders no longer occur in practice, so the fallback path stays a safety valve. +- The `toolOrder` key rides the app → `agent-core` → `SystemPrompt` forwarding chain, so deployments set it next to `persona` in the app config; `dsh-llm` and the agent loop are untouched. + +## Testing + +Unit tests on `dsh-system-prompt` pin the ordering semantics (lexicographic default, listed/ignored/rest placement, stable handling of shared names, provider-order independence), the pre-waterfall contract (listeners observe the canonical list; a listener-appended tool is not re-sorted), and each invalid-list rejection at load. Loop-level tests assert the `request/header` fold carries the canonical order for scrambled registration orders (identical across permutations), that a configured `toolOrder` reaches both the logged header and the dispatched deep-frozen request, and that the frozen loop-built envelope survives to the adapter. Forwarding is asserted at every level that exposes the key (`dsh-agent-core`, `dsh-stdio-agent`, `dsh-acp-agent`). The snapshot tier replays all scenarios against re-recorded goldens whose headers carry the canonical order. diff --git a/packages/core/agent-core/README.md b/packages/core/agent-core/README.md index 353e68332d..3f2ff08c0e 100644 --- a/packages/core/agent-core/README.md +++ b/packages/core/agent-core/README.md @@ -35,11 +35,11 @@ This is the [interface/implementation/consumer seam](../../../docs/rfc/implement ```ts import type { Config } from '@deepseek-ai/dsh-agent-core' -// { agents?, persona? } — the schema is z.intersect([AgentLoop.Config, SystemPrompt.Config]), +// { agents?, persona?, toolOrder? } — the schema is z.intersect([AgentLoop.Config, SystemPrompt.Config]), // so validation and defaulting can never drift from the owners'. ``` -The bundle FORWARDS each field to the child that owns it: `agents` to `agent-loop` (default `[]`), so each app supplies its own pre-created agents — a stdio app pre-creates a `main`; the ACP app pre-creates none (it creates agents on demand at `session/new`) — and `persona` to `dsh-system-prompt` (default `''`), the deployment's persona section.

The scope dispatch is now two-phase: requests accumulate per statement (null = whole statement for a direct export modifier or ambient scope; name sets union across lists, so two lists naming different declarators of one statement both count), then each surfaced statement is checked once with the declarator filter.

Model exposure is zero new code: `dsh-tool-subagent` is loaded once per provider with a distinct `toolName` (`subagent_claude_code`, `subagent_codex`). No new session events are needed — the only model-visible artifact is the tool result, so reconstructability holds exactly as it did for ACP. To be explicit about the boundary: the session log reconstructs the model-visible transcript, not workspace mutation history — a child granted write access mutates files as an ambient side effect outside the log, exactly as the bash tools and the ACP backend already do; replay reproduces requests, not the disk. + +## Verified interface facts (pinned versions) + +Both integration surfaces were verified against pinned implementations before this proposal — types and bundled source read, keyless spikes run — not from vendor docs alone. The pins are the verification baseline, not a runtime contract: the backends perform no runtime version probe (no `codex --version` gate, no SDK version sniffing). Compatibility is enforced at development time — every dependency bump re-runs the keyless suites against the real load path — and at runtime by failing loudly: a protocol-level surprise settles `error` via `onError`, never a silent misbehavior. + +**`@anthropic-ai/claude-agent-sdk` 0.3.202.** `options.env` REPLACES the child environment (no merge with `process.env`), which is exactly what the scrub needs. `settingSources` defaults to loading ALL filesystem settings — isolation requires explicitly passing `[]`. Result subtypes are `success` | `error_during_execution` | `error_max_turns` | `error_max_budget_usd` | `error_max_structured_output_retries`. On abort the SDK escalates the CLI child itself: stdin EOF immediately, SIGTERM ~2s later if the child ignores it (observed; no leftover processes) — no bespoke kill fallback needed. `outputFormat: {type: 'json_schema'}` and an `agents` option exist, giving future landing points for the seam's `outputSchema` capability and named subagent types; both are out of scope here. + +**codex CLI 0.142.5, `codex app-server` (v2 vocabulary).** LF-delimited JSON, JSON-RPC 2.0 shapes with the `"jsonrpc"` header omitted. + +- Lifecycle: `initialize{clientInfo}` + `initialized` → `thread/start` (accepts `cwd`, `model`, `sandbox`, `approvalPolicy`, `ephemeral`; succeeds unauthenticated) → `turn/start{threadId, input:[{type:'text',text}]}` returns an `inProgress` turn immediately; the terminal signal is the `turn/completed` notification carrying `Turn{status: completed|interrupted|failed|inProgress, error}`. +- Approvals are server-initiated requests — `item/commandExecution/requestApproval`, `item/fileChange/requestApproval`, `item/permissions/requestApproval`, `item/tool/requestUserInput`, `mcpServer/elicitation/request` — answered with `accept`/`decline`-family decisions. +- Auth: `account/login/start{type:'apiKey', apiKey}` is a first-class RPC and `account/read` reports `requiresOpenaiAuth` — and an unauthenticated `turn/start` does NOT fail fast (it hangs in retry), so the backend MUST pre-check auth and settle `error` loudly instead of waiting on the turn. +- Isolation: `CODEX_HOME` redirection is honored (the `initialize` response echoes it, so tests can assert isolation), and `ephemeral: true` threads leave no session files at all. + +## Isolation and credentials + +Deployments authenticate with API keys only, and the child must not see the host user's Claude Code / Codex configuration: behavior has to be a function of `cordis.yml` alone. Each run gets a fresh `mkdtemp` config dir — `CLAUDE_CONFIG_DIR` for Claude Code (paired with an explicit `settingSources: []`), `CODEX_HOME` for Codex — removed best-effort on dispose; a config field can pin a persistent dir instead. The child env reuses the ACP backend's `buildChildEnv` semantics verbatim via the extraction: the ambient env is forwarded MINUS credential-shaped vars (`/KEY|SECRET|TOKEN/i`), with `config.env` layered on top — so `PATH`, `HOME`, `TMPDIR`, locale, and proxy vars survive and the CLIs run normally, while only credential-shaped ambient vars are scrubbed (`ANTHROPIC_API_KEY` enters explicitly through `config.env` for Claude Code), and the Codex key travels via the `account/login/start` RPC into the isolated `CODEX_HOME` rather than a hand-written `auth.json`. + +## Permission and approval policy + +Instead of collapsing to ACP's single `permission: allow|reject` knob, each backend exposes its engine's native vocabulary as config, with conservative defaults: Claude Code gets `permissionMode` (default `default`) plus `permission: allow|reject` (default `reject`) as the `canUseTool` auto-answer for whatever falls through; Codex gets `sandboxMode` (default `read-only`) and `approvalPolicy` (default `never`) plus the same `permission` fallback for approval requests that still arrive. Defaults are deliberately do-no-harm (the out-of-box child cannot write files); examples demonstrate opening up (`acceptEdits` / `workspace-write`). The mechanical rule: EVERY server-initiated request is settled programmatically and promptly — the enumerated approval/user-input/elicitation requests by the configured policy, an unknown request method with a JSON-RPC method-not-found error response (never left pending), unknown notifications consumed — so no child request can wedge a turn waiting on an answer that will never come. Prompts never reach a human in this cut, matching ACP. + +## StopReason mapping + +Claude Code: `success` → `completed`; `error_max_turns`, `error_during_execution`, `error_max_budget_usd`, `error_max_structured_output_retries` → `error` (aligning with the ACP call on `max_turn_requests`: an unfinished task is not success); generator abort → `aborted`; anything unknown → `error`. Codex: `Turn.status` `completed` → `completed`; `interrupted` → `aborted`; `failed` with `codexErrorInfo: 'contextWindowExceeded'` → `max-tokens`, any other `failed` → `error`; transport/spawn/auth-precheck failure → `error` (or `aborted` if cancel was requested). In both, `cancel()` is the ACP shape: flag + abort/interrupt + a cancel-settled race arm so an uncooperative child cannot stall the result. + +Liveness posture, stated explicitly: teardown timing is config, turn duration is not. Both backends take the dispose ladder's grace periods as defaulted validated config fields (the ACP backend's `disposeEofGraceMs`/`disposeGraceMs` shape, carried by the extraction), but there is deliberately NO turn-duration or startup timeout — matching ACP, liveness during a turn belongs to the caller via `cancel()`/the abort signal, a subagent turn is legitimately minutes long, and the Codex auth precheck removes the one verified guaranteed-hang; a deployment wanting a wall-clock bound cancels from the parent. + +## Testing + +Named at every tier per the root AGENTS.md rule, and de-risked up front: + +- **Keyless unit/integration**, mirroring the ACP spec list per backend (round-trip and output accumulation, every stop mapping, both cancel paths, already-aborted, permission auto-answer under both policies, unknown-message tolerance, bad-command spawn failure, HMR provider cleanup, export shape, isolation assertions on child env and temp-dir removal; Codex adds the auth-precheck failure path). Claude Code's harness is a scripted fake `claude` executable behind `pathToClaudeCodeExecutable` driven by the REAL SDK — a spike already passed end-to-end keyless in 24ms (the fake CLI answers one `control_request/initialize` and speaks plain stream-json, ~40 lines). Codex's harness is a scripted mock app-server subprocess speaking the verified wire protocol, the `mock-acp-server.ts` shape. +- **With-key e2e** per backend: the real engine does real file work verified on disk, under a pinned opened-up config so acceptance and the do-no-harm defaults don't collide — `permissionMode: 'acceptEdits'` for Claude Code, `sandboxMode: 'workspace-write'` + `approvalPolicy: 'never'` for Codex; self-skips report exactly what is missing (binary vs key). CI has no secrets, so these run locally per the with-key policy. +- **Snapshot**: deferred as `TODO(claude-code-subagent-replay)` / `TODO(codex-subagent-replay)` — the same distinct replay shape the ACP backend deferred ([the per-session replay RFC](../../implemented/testing/2026-06-22-subagent-snapshot-replay.md)); the keyless suites carry deterministic coverage meanwhile. + +## Alternatives considered + +### Why not the official `@openai/codex-sdk` instead of a hand-rolled client? + +The dispose ladder and env scrub require owning the child process (spawn args, env, signals, exit await); the SDK hides the process. The wire format is trivial to frame (LF JSON), the shapes are generatable per pinned version (`codex app-server generate-json-schema`), and the repo precedent (`hook-protocol`) is to own thin protocol cores rather than wrap someone's runtime. The SDK would save protocol-evolution maintenance but costs the exact control this backend exists to have. + +### Why not a model-visible `subagent_type` parameter (one Task-style tool)? + +Claude Code's own Task tool puts the subagent type in the model-facing schema, selecting a prompt-plus-toolset persona. Here the choice is between EXECUTION ENGINES, and only the deployer knows which engines have credentials configured — so selection stays deployment config, preserving `dsh-tool-subagent`'s documented one-provider-per-tool contract. A persona-style type selector would be a separate RFC against the tool, not the backends. + +### Why not login-state credentials and the user's own config? + +Inheriting `~/.claude` / `~/.codex` (subscription login, user settings, skills, MCP servers) would make child behavior depend on host-machine state and punch an implicit exception through the "credentials enter explicitly via `config.env`, never ambiently" rule the ACP backend and bash executor established. API-key-only plus forced config-dir isolation keeps runs reproducible; deployments wanting shared state can point the config-dir field at a persistent directory deliberately. + +### Why not a driver-injection seam for the Claude Code keyless tests? + +Injecting a fake `query()` would mock our own boundary and leave the real SDK load path untested (the real-over-mock policy in docs/testing.md). The risk that justified considering it — the SDK↔CLI stream-json control protocol being internal — was retired by the spike: the fake-CLI harness works against the real pinned SDK today. If an SDK upgrade breaks the mock, the keyless suite fails the upgrade PR, which is the gate working. + +### Why not ACP adapters (e.g. `claude-code-acp`) reusing the existing backend? + +Community shims wrap both engines in ACP, which would make them "just config" on `dsh-subagent-acp`. But that inserts an unofficial third-party layer between the harness and the engine, erases the native control surfaces this RFC exposes (permissionMode, sandboxMode/approvalPolicy, config-dir isolation, apiKey RPC), and trades first-party protocol stability for a shim's release cadence. First-party surfaces — the Agent SDK and the app-server — are the supported integration points. + +## Acceptance criteria + +On a machine with both engines and keys configured: a REPL-driven model completes one real file task through `subagent_claude_code` and one through `subagent_codex`, the tool result being the child's final answer, with only `tool/call` + `tool/result` in the parent session log. Keyless suites pass at 100% per-file coverage in a credential-less environment, asserting isolation (scrubbed child env, no temp config dirs left after dispose) and that child behavior is unchanged by the presence or absence of `~/.claude` / `~/.codex`. Cancelling a parent turn quiesces both backends in bounded time with no leftover child processes. E2e suites self-skip cleanly, naming the missing prerequisite. + +## Risks + +- `codex app-server` is CLI-flagged experimental and its v1/v2 vocabularies coexist; the client pins 0.142.5, implements v2 only, and consumes unknown methods/notifications without crashing, but a future codex bump can still force rework (regenerate schemas and re-run the keyless suite on every bump — the development-time enforcement behind the no-runtime-version-probe stance above). +- The Claude Code fake-CLI mock rides an internal protocol: any SDK upgrade must go through the keyless suite, and a breaking control-protocol change means reworking the mock (fallback: the driver-injection seam rejected above becomes the escape hatch). +- The SDK's optionalDependencies weigh ~280MB per platform — accepted, and confined to the one backend package. +- The SDK's SIGKILL branch beyond EOF→SIGTERM was not observed and is trusted; e2e keeps a no-leftover-process assertion. +- Codex is a deployment prerequisite (no npm-bundled binary); a missing or incompatible binary surfaces as a loud spawn/protocol `error`, not a version probe. +- Every run pays a fresh child process and only the final answer surfaces — thoughts, tool cards, and usage are consumed and dropped; pooling, intermediate-progress surfacing, `sendMessage`/`resume`, `outputSchema` via the SDK's `outputFormat`, and named subagent types via the SDK's `agents` option are all deliberate deferrals.

charset=UTF-8 Content-Transfer-Encoding: 8bit Review follow-up (#196): a listed name with no registered tool was silently ignored; misconfiguration must block work instead. The check lives in the assembly — the earliest moment the registered tool set exists (tool plugins register after the service constructs) and the only universal one (cordis has no "all plugins loaded" event; registrations change at any time). assemble() is now async so the throw surfaces as a rejection rather than a synchronous escape from a Promise-returning method. Blast radius, pinned by a loop-level test: the rejection reaches the turn's outer catch — the turn closes balanced with an `error` reason, agent/error mirrors it, no step opens, no request/header is logged, no request reaches the adapter, and the agent returns to idle; every turn fails identically until the config is fixed. A boot-time validation pass was considered and rejected (recorded in the RFC).

post-execute accept MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The cross-seam blocker: structured_output recorded its value in the tool BODY, before tools/post-execute could block the call — a PostToolUse hook's block turned the logged result into isError while readResult still returned structured success and the continuation veto ended the turn. Two-phase commit: the body validates and STAGES (RunState.pending); a fourth runtime listener on tools/post-execute — prepend, so await next() returns the composed final decision — promotes the stage to captured only on an accepted call, and clears it on every path. A block now yields a consistent pair: the model and log see the isError feedback, the run settles error with no structured value, and the turn continues so the model can react.

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. + +An earlier draft of this RFC designed Code Mode as an add-on consumer plugin with zero core changes, deferring the execution substrate to a follow-up. Both constraints are dropped here, deliberately. First, the harness is pre-release and optimizes for the correct foundation over blast radius: tool presentation is the registry's own concern, and bolting a second presentation onto it from outside means transforming the registry's contribution after the fact — a waterfall listener whose correctness depends on listener ordering, which fights the [reconstructable-requests](../../implemented/architecture/2026-07-05-reconstructable-requests.md) design instead of riding it (that refactor removed request mutation from `agent/request`, the seam the old draft relied on). Second, the substrate question is answerable now: a Node `worker_threads` runtime gives real containment — separate isolate, empty environment, heap caps, and a `terminate()` that reliably stops a hot synchronous loop — where the old draft's `node:vm` stub had none of those, and it fits the harness's existing trust model (§Trust posture) without a hardening follow-up. + +## Proposal + +Three decisions, each elaborated in its own section below: + +1. **Code Mode is a first-class presentation mode of `ToolRegistry`** (`dsh-tools`), selected by a validated `mode` config: `'native'` (today's behavior, the default), `'code'` (the wire carries exactly one tool, `run_code`, plus a generated SDK `.d.ts` in the system prompt), or `'both'` (native schemas *and* `run_code` + SDK). The registry's existing tool-schema provider contributes whatever the mode dictates, so the wire tool list is shaped at its source — no interception, no listener-ordering caveats — and the logged request header records it for free. +2. **Code execution is a capability seam** — a new group `packages/code-runtime/` with the interface package `@deepseek-ai/dsh-code-runtime` owning `ctx.codeRuntime` ([capability seams](../../implemented/architecture/2026-06-13-capability-seams.md); consumer = `dsh-tools`, with core-consumes-a-seam precedent in `agent-loop` → `dsh-llm`). The runtime knows nothing about tools: it is handed a program and named async bindings, runs the program, and reports `{ value, logs, error? }`. Language and substrate are backend properties, so a future Python or container backend is a new implementation package, not a redesign. +3. **The shipped implementation is `@deepseek-ai/dsh-code-runtime-worker`**: one fresh Node worker thread per run, executing the model's TypeScript after type-strip, with bindings bridged over the message port, an empty environment, configurable heap/output/time caps, and hard termination. Its trust posture is bash-equivalent by design — no unsafe-acknowledgement flags — because the harness already ships `dsh-bash-local`, which executes arbitrary model-written shell commands with strictly *more* ambient authority. + +### The registry owns the mode + +`ToolRegistry` gains a schemastery-validated config (`static Config`), its first: `mode: 'native' | 'code' | 'both'`, default `'native'`. A deployment flips it from `cordis.yml` (`tools: { mode: code }`) — no code edit, per the no-hardcoded-tunables convention. + +**Wire tool list = the provider's contribution.** The registry already feeds the assembly through `ctx.systemPrompt.tools(() => this.schemas())`; the provider becomes mode-aware: `'native'` contributes all schemas (unchanged), `'code'` contributes only `run_code`'s schema, `'both'` contributes all schemas plus `run_code`. Because [`PromptAssembly.tools` is the single source the loop's request header snapshots](../../../../packages/core/system-prompt/src/index.ts), the collapse is automatically logged and reconstructable — model-visible ⟺ logged holds with zero new mechanism, and there is no seam left where another party could accidentally re-add tools (the `system-prompt/assemble` waterfall can still deliberately transform the assembly, as ever). + +**Interaction with `toolOrder`, stated up front:** a configured `systemPrompt.toolOrder` naming native tools rejects every assembly under `mode: 'code'` (those names are no longer contributed), by the existing fail-loud rule for unlisted names. This is correct behavior, not a bug: a deployment switching modes updates its order config or drops it. + +**The SDK prompt section.** Under `'code'` and `'both'` the registry registers one lazy prompt section (`tools:sdk`, in the 100–199 tool-guidance order band) whose thunk regenerates, at each assembly, a TypeScript declaration of every registered tool except `run_code` itself, plus fixed usage instructions. The thunk reads the live store and emits tools in lexicographic name order, so its output is deterministic and stable across steps — an unchanged tool set produces byte-identical text (prefix-cache-friendly; a mid-session registration surfaces as one logged header delta, exactly like a native-mode tool change). + +**Codegen.** A pure `jsonSchemaToTs(schema)` module inside `dsh-tools` (sibling of `json-schema.ts` — `schemas()` and the SDK are two projections of the same store) maps the JSON-Schema subset the `defineTool` DSL emits (object/string/number/boolean/array, `properties`, `required`, string `enum` → literal union, nested objects, array `items`, `description` → JSDoc) to a TS type literal. It is **total**: any construct outside that subset (`$ref`, `oneOf`/`anyOf`, `integer`, future MCP shapes, …) degrades to `unknown` without throwing. Because `ToolSchema.name` is an arbitrary string, the SDK is declared as one object constant — `declare const tools: { "some-mcp-tool"(args: …): Promise; bash(args: …): Promise; … }` — quoted keys make every name reachable with no sanitization or alias-collision logic. Typing is advisory (the runtime executes type-stripped JS); the instructions say so. + +### The run_code tool and the dispatch bridge + +Under `'code'` and `'both'` the registry registers `run_code` in itself as an ordinary tool — one required parameter `{ code: string }` — so the unchanged loop dispatches it through the normal pipeline and `tools/pre-execute` / `tools/post-execute` gate it like any other call (a permission plugin can inspect the program text before it runs). Its `execute(args, exec)`: + +1. **Builds the bindings**: for every registered tool except `run_code`, an async function that (a) checks `exec.signal?.aborted` before and after (throwing stops the program — necessary because `ctx.tools.execute()` converts errors to `isError` data), (b) awaits its turn on the **per-run serialization queue** (below), (c) calls `this.execute({ callId, name, arguments, agent: exec.agent, signal: exec.signal })` with a deterministic sub-id `` CallId(`${exec.callId}:code:${n}`) ``, (d) appends a `tool/code-dispatch` session event, and (e) maps the result: success → the text-block contents joined as a `string` (non-text blocks become placeholders, an MVP limitation), `isError` → **the binding rejects** with an `Error` carrying the result text. Rejection is the deliberate model-facing contract — real code signals failure by throwing, `try/catch` and `Promise.all` short-circuiting behave as every model has seen them behave — where the old draft's `{ output, isError }` envelope made error handling a bespoke convention. +2. **Runs the program**: `ctx.codeRuntime.run({ program: args.code, bindings: [{ global: 'tools', functions }], signal: exec.signal })`. +3. **Surfaces the outcome**: a successful run returns one text block — the captured console/stdout output followed by the rendered return value (if any) — plus a `meta` payload (capped logs, dispatch count) for presentation. A run with `result.error` throws a `CodeRunFailedError extends HarnessError` (`code: 'CODE_RUN_FAILED'`, message = the error kind and text plus captured logs so the model can self-correct); the registry's existing catch turns it into a structured `isError` result. + +**Concurrency: serialized, enforced by the binding.** The bindings are async, so a model writing `Promise.all([tools.a(…), tools.b(…)])` starts both immediately — concurrent dispatch would be the *default*, while the tool contract still carries no concurrency-safety metadata (the open parallel-execution TODO). Each `run_code` invocation therefore owns a dispatch queue and every binding call chains onto it, so even `Promise.all` executes the underlying `ctx.tools.execute()` calls one at a time in submission order; when the run settles, queued-but-unstarted dispatches are abandoned. Lifting this per-tool once tools can declare themselves concurrency-safe is deferred work, same as before. + +**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 `Run code`, `rawInput` = the program text; `presentResult` → a `generic` card whose content is the captured output (from `meta`). Not a `terminal` card: that card's semantics are "a shell command in a working directory", which a program is not. + +### Observability: `tool/code-dispatch` + +Each sub-dispatch appends one session event, declared by `dsh-tools` via `SessionEventMap` declaration merging (the map is merge-extensible for exactly this): `tool/code-dispatch` with `{ parentCallId, subCallId, name, arguments, isError, resultSummary }`. It is log-only — `deriveEventMessage()` ignores unknown event types by design, so sub-calls never re-enter model context — but persistence and UIs get every call. A `run_code` execution arriving without `exec.agent` (the loop always supplies it; direct programmatic calls may not) still runs and simply skips event logging, exactly as the `ToolExecution` contract allows. + +### The code-runtime seam + +`packages/code-runtime/code-runtime/` — `@deepseek-ai/dsh-code-runtime`, depending only on `cordis`. An abstract `CodeRuntime extends Service` (`super(ctx, 'codeRuntime')`) plus the vocabulary: + +- `CodeRunRequest = { program: string; bindings: CodeBindingNamespace[]; signal?: AbortSignal }` +- `CodeBindingNamespace = { global: string; functions: Record Promise> }` — the runtime exposes each namespace as a global object of async functions inside the program; binding arguments and resolutions must be structured-cloneable (a runtime may cross a serialization boundary; ours does). +- `CodeRunResult = { value?: unknown; logs: CodeLogEntry[]; error?: CodeRunFailure }` — an error is a field on a resolved result, never a rejection of `run()`. +- `CodeLogEntry = { source: 'console' | 'stdout' | 'stderr'; level?: 'log' | 'info' | 'warn' | 'error' | 'debug'; text: string }` +- `CodeRunFailure = { kind: 'exception' | 'timeout' | 'abort' | 'worker-exit'; message: string }` — orthogonal outcomes reported independently per [defensive patterns](../../../defensive-patterns.md); a timed-out run is not an exception, an abort is not a timeout. +- Two readonly backend descriptors, informational not gating: `language` (what the program must be written in — `'typescript'` for the shipped backend; a Python backend would say so, and pair with its own SDK generator on the presentation side) and `isolation` (`'worker-thread'` for the shipped backend; `'process'`, `'container'`, … for future ones). `dsh-tools` requires `language === 'typescript'` in the MVP — its codegen emits TS — and fails the assembly loudly otherwise, the same misconfiguration idiom as `toolOrder` violations (as when `mode` is non-native with no `ctx.codeRuntime` loaded at all). + +Per explicit-over-implicit at seams, the request spells out everything the runtime acts on; defaulting (timeouts, caps) is the implementation's validated config, never a hidden `??` inside `run()`. The seam split is justified by real planned divergence on both axes — substrate (worker now; container/microVM later) and language (the Python/AssemblyScript direction sketched in the earlier draft survives as future work) — not by speculation: `dsh-tools` consumes the interface today and tests against a trivial in-repo fake, exactly the interface/implementation/consumer shape of the bash template. + +### The worker-thread runtime + +`packages/code-runtime/code-runtime-worker/` — `@deepseek-ai/dsh-code-runtime-worker`. Per `run()`: + +1. **Type-strip host-side** with Node's built-in `stripTypeScriptTypes` (`node:module`; the repo floor is node ≥ 24, and the API is position-preserving, so runtime error line numbers match the model's source). Strip-only mode rejects non-erasable syntax (`enum`, namespaces) — that rejection returns as `error.kind: 'exception'` with Node's message, the SDK instructions say "erasable TypeScript only", and the model self-corrects like any other program error. A syntax-level failure never spawns a worker. +2. **Spawn one fresh `Worker` per run** from the package's own bootstrap module: `env: {}` (truly empty — stronger than the scrubbed-env rule for spawned commands), `resourceLimits` from config, `stdout`/`stderr` captured into `logs` rather than inherited. No pooling and no cross-run state: a program's world dies with its worker, which keeps runs reconstructable from the log alone and makes state bleed unrepresentable. +3. **Execute** in the bootstrap: the stripped program becomes the body of an `AsyncFunction` whose parameters are the binding globals and a capturing `console` shim, so top-level `await` and `return` work and the program's completion value is the run's `value` (structured-cloneable values cross as-is; anything else is replaced by its `util.inspect` rendering, documented). +4. **Bridge bindings over the message port**: each binding function in the worker posts `{ id, global, name, args }` and awaits the reply; the host validates the name against the request's bindings, invokes, and replies `{ id, ok, value }` or `{ id, ok: false, message }` (a host-side binding rejection becomes a program-side rejection). Unknown names, duplicate ids, and post-settlement messages are rejected or ignored — the port protocol assumes a hostile peer, because the peer runs model code. +5. **Enforce caps**: the compute-time budget (`timeoutMs`) ticks only while no binding call is pending — it bounds runaway worker compute, not tool latency — and expiry, `signal` abort, and run completion all funnel into `worker.terminate()`, which ends hot synchronous loops too (measured; this was `node:vm`'s unfixable gap). Heap overflow surfaces as the worker's OOM exit → `error.kind: 'worker-exit'`. Log and value sizes are capped by config (`maxLogBytes`, `maxValueBytes`), truncation marked in-band. All caps are validated config fields with defaults (`timeoutMs: 60_000`, `maxLogBytes: 65_536`, `maxValueBytes: 32_768`, `maxOldGenerationSizeMb: 512`), changeable from `cordis.yml`. +6. **Dispose to quiescence**: the service's own disposal terminates in-flight workers and *awaits* their exits before resolving, per [defensive patterns](../../../defensive-patterns.md). + +### Trust posture + +The worker runtime is **containment, not a security boundary**, and the RFC says so without ceremony. Model code in the worker can reach Node globals — `fetch`, `process` (with an empty env) — so a deliberately adversarial program has ambient authority comparable to what the harness's own `bash` tool already grants every model turn: `dsh-bash-local` runs arbitrary model-written commands with the host filesystem, network, and a scrubbed-but-populated environment. Code Mode is gated where bash is gated — `tools/pre-execute`, where permission/sandbox plugins veto or approve the program before it runs — and adds containment bash does not have: empty env, heap caps, hard termination, a separate isolate. The earlier draft's two-flag unsafe ceremony (`{ unsafe: true }` constructor + `allowUnsafeRuntime`) existed for a `node:vm` stub with *no* containment and is dropped with it; demanding scarier flags for the better-contained executor than for bash would be posture theater. A deployment that needs a hard boundary (untrusted multi-tenant input) needs it for bash too; that is a future `isolation: 'container'` backend, and the `isolation` descriptor exists so such a deployment can tell backends apart. + +### What the model sees + +The `tools:sdk` section carries the `.d.ts` plus fixed instructions: the program is the body of an async TypeScript function (erasable syntax only — no `enum`/namespaces; type annotations are advisory); call tools as `await tools.name(args)` (quoted access for exotic names); a failed tool call **rejects** with an `Error` carrying the tool's error text — catch it to handle and continue; calls run **sequentially** even under `Promise.all`; emit results via `return` and/or `console.log`, and only that curated output returns to the context — intermediate tool results never do. That last line is the payoff the whole design serves: output-side context cost becomes the model's own editorial decision. On the input side the `.d.ts` is not free — for a large tool surface it can rival the native JSON schemas it replaces (and `'both'` pays for the two side by side) — but it is prefix-stable, so provider prefix caching amortizes it; the win is workload-dependent and the RFC claims no more. + +## Plan + +Four stacked PRs, each gates-green (`typecheck`, `lint`, `test:coverage`, `test:snapshot`, `doc-sync`, `verify-module-graph`, `build`, `hygiene`) with docs updated in the same change: + +1. **This RFC revision** (docs-only): the file rewritten as above (renamed `2026-06-15-code-mode.md`, same first-proposed date), regenerated RFC index. +2. **`dsh-code-runtime`** (interface package): the group `packages/code-runtime/`, abstract `CodeRuntime`, vocabulary types, ctx-key declaration, group README + package README + catalog updates. Unit tier: HMR safety (dispose removes `ctx.codeRuntime`), contract docs. This package has no behavior to snapshot or e2e; its coverage story is unit-only by design. +3. **`dsh-code-runtime-worker`**: the implementation above. Unit tier (real workers, no mocks — they are cheap and local): output/value capture, log source attribution, error kinds (exception incl. non-erasable syntax, timeout vs abort vs worker-exit under OOM), compute-time-only timeout (a slow binding does not expire the run), binding bridge hostility cases (unknown name, duplicate id, post-settlement message), structured-clone fallback, cap truncation, `env` emptiness verified from inside the program, dispose-awaits-exit. A real-load-path test runs the built package (`lib/`) so the worker entry resolves both unbuilt (tsx) and built — the published-bin guard from [docs/testing.md](../../../testing.md). +4. **Native code mode in `dsh-tools`** + the end-to-end surface: mode config, provider switch, `tools:sdk` section, `jsonSchemaToTs`, `run_code` + dispatch bridge + serialization queue, `tool/code-dispatch` event; [docs/architecture.md](../../../architecture.md) (tool-pipeline section + `ctx.codeRuntime` service row) and the [adding-a-tool cookbook](../../../cookbook/adding-a-tool.md) cross-reference updated in the same change; an `examples/` leaf + `demo:code` script wiring the worker runtime with `mode: 'code'`; move this RFC to `implemented/`. Coverage named per tier now, per the plan-time rule: **unit** — codegen table (DSL subset, quoted names, `unknown` degradation, determinism), provider contribution per mode, `toolOrder × mode` rejection, missing-runtime/wrong-language loud failures, serialization non-overlap (a probe tool records enter/exit under `Promise.all`), abort stops the queue, binding rejection on `isError`, `CodeRunFailedError` → structured `isError`, event payloads, `deriveMessages()` ignores the event, HMR safety (mode flip via config reload removes tool + section); **e2e (with-key, self-skips)** — a real model, `mode: 'code'`, a task requiring two tool calls and curation, asserting the wire tool list was exactly `run_code` and the transcript's dispatch events; **snapshot (keyless replay)** — goldens for a `run_code` turn in `'code'` and `'both'`, pinning the SDK section text, the collapsed header tools, dispatch events, and the result card. + +The four PRs land in order (each on the previous); per stacked-review practice, review fixes land on the PR that introduced them and merge down. + +## Alternatives considered + +**An add-on consumer plugin, zero core changes (the previous draft of this RFC).** Rejected on both halves. The wire-collapse half aged out from under it: it targeted the `agent/request` waterfall, which [reconstructable requests](../../implemented/architecture/2026-07-05-reconstructable-requests.md) has since re-typed to call-config-only, and the surviving alternative — transforming the assembly a waterfall listener receives — is strictly worse than contributing the right list in the first place (transformation must undo `toolOrder` canonicalization it cannot see the config for, and its correctness depends on where it sits in a listener chain). The deeper reason is ownership: which tools the model is offered, in which representation, is the registry's single concern — `schemas()` for function calling and the SDK for Code Mode are two projections of one store, and splitting the second projection into a satellite package would preserve a boundary the domain does not have. + +**`node:vm` as the reference runtime, hardening deferred (also the previous draft).** Rejected: `node:vm` is not isolation (prototype-chain escapes reach the host realm), cannot interrupt a hot loop, and forced the draft into a two-flag unsafe ceremony plus a mandatory follow-up RFC. The worker thread delivers the missing properties now — separate isolate, empty env, `resourceLimits`, reliable `terminate()` (all verified by probe before this revision) — at bash-equivalent trust, so the reference implementation and the production one are the same package and the ceremony dissolves. + +**Result elision / summarization over native tool-calling.** Addresses only the context-bloat half of the problem: trimming old `tool-result`s (now cheap to add as a logged surface replace, per the reconstructable-requests consequences) still pays one model round-trip per call and cannot express loops, branches, or joins. Complementary, not competing; it can layer under Code Mode for residual native calls. + +**Parallel native dispatch in the loop.** The other answer to round-trip cost; still valid future work (the open TODO), still blocked on concurrency-safety metadata, and still no composition — it parallelizes calls the model already decided on in one step. Code Mode's serialized-queue decision keeps the two compatible: when the metadata lands, both native parallel dispatch and per-tool binding parallelism unlock together. + +**Always-exclusive (Cloudflare-faithful, no mode).** Rejected for this SDK's primary consumer: a coding agent's bread-and-butter single calls (`bash`, `read`, `edit`) are already ideal as native calls, and forcing every edit through a program taxes the common case. The mode config keeps the faithful form (`'code'`) one line away without imposing it. + +**Per-tool visibility tiers (this tool native, that tool code-only).** Deferred again, knowingly: it needs per-tool metadata and a presentation split that `'native' | 'code' | 'both'` does not, and every learning it depends on (how models actually split usage under `'both'`) arrives only after this ships. + +**Sanitized identifier aliases in the SDK** (`my-tool` → `my_tool`, Cloudflare's approach). Rejected: quoted keys on a `declare const` make every name reachable with zero alias-collision logic; models handle `tools["my-tool"](…)` fine. + +**A REPL-style persistent kernel** (state survives across `run_code` calls). Rejected for the MVP: cross-call state would be invisible to the session log, breaking the reconstructability guarantee that every request is a pure function of the log; fresh-per-run keeps it. A kernel-style backend remains expressible behind the seam later, with its own logging story. + +## Acceptance criteria + +- `mode: 'native'` (and unset) is byte-for-byte today's behavior: same assemblies, same headers, same snapshots. +- Under `mode: 'code'`, the assembled tool list (and thus the logged `request/header`) is exactly `[run_code]`; under `'both'`, every native schema plus `run_code`; the `tools:sdk` section is present in both, absent under `'native'`, and its text is deterministic for a fixed tool set (byte-identical across consecutive assemblies). +- The generated `.d.ts` covers every registered tool except `run_code`, non-identifier names via quoted keys, unsupported schema constructs as `unknown`, without codegen ever throwing. +- A program calling two tools returns only its curated output; each sub-call appears as a `tool/code-dispatch` event ordered by log `seq`, flows through `tools/pre-execute`/`post-execute` (a deny reaches the program as a binding rejection), and never enters derived messages. +- `Promise.all` over three bindings produces non-overlapping `ctx.tools.execute()` intervals (probe-tool assertion); aborting mid-program stops the worker and dispatches nothing further. +- Worker runtime: a hot `for(;;){}` run ends at the compute-time budget with `error.kind: 'timeout'`; a pending binding call does not consume that budget; OOM under `resourceLimits` yields `kind: 'worker-exit'` with the host process healthy; `process.env` inside a program is empty; non-erasable syntax yields `kind: 'exception'` without a worker spawn; disposal awaits worker exit. +- Misconfiguration is loud before any model request: non-native mode with no `ctx.codeRuntime`, a runtime whose `language ≠ 'typescript'`, and `toolOrder` naming a non-contributed tool all reject the assembly with actionable messages. +- The demo runs against the real API via `demo:code`; the snapshot goldens replay keylessly; all repo gates pass on every PR of the stack. + +## Risks + +**The worker is not a hard security boundary.** Deliberate and documented (§Trust posture): posture equals the existing bash tool, containment exceeds it, gating uses the same seams. Deployments needing more need a future `isolation: 'container'` backend — tracked as the seam's designed extension, not a TODO on this design. + +**`stripTypeScriptTypes` is marked experimental.** It is also what Node itself runs `.ts` files with on this repo's node floor. Mitigations: the runtime's unit suite pins the behaviors relied on (position preservation, erasable-only rejection message shape loosely), the call sits behind one private function, and `amaro`/`sucrase` are drop-in replacements if the API shifts. The erasable-only subset is a model-facing contract line, and the error path is a working feedback loop, not a dead end. + +**Prompt cost of the SDK, especially under `'both'`.** The `.d.ts` can rival the native schemas it complements; `'both'` carries two representations. Prefix stability + provider caching amortize per-session cost; the mode is per-deployment; the RFC makes no unconditional-savings claim. Measured guidance (when to prefer which mode) is explicitly post-ship learning. + +**Registry scope growth.** `dsh-tools` absorbs codegen, a tool, a bridge, and an event. Contained by module boundaries inside the package (`ts-types.ts`, `code-mode.ts` beside `schema.ts`/`json-schema.ts`/`presentation.ts`) and by the seam: everything substrate-shaped lives behind `ctx.codeRuntime`. + +**Structured-clone limits at the binding boundary.** Tool bindings pass JSON-shaped arguments and return strings in the MVP, comfortably cloneable; the seam contract states the constraint so a future binding producer cannot discover it in production. Non-text sub-result content is reduced to placeholders — a known MVP limitation, recorded in the SDK instructions. + +**Serialized-only sub-dispatch.** `Promise.all` gains no wall-clock parallelism yet, only fewer round-trips; models may over-expect. The instructions state it; lifting it is tied to the same concurrency-safety metadata the native parallel-dispatch TODO needs. + +**Timer-pause bookkeeping.** Compute-time-only budgeting adds a small state machine (pause on RPC out, resume on reply) whose bugs would misattribute time. It is unit-tested from both sides (slow binding ≠ timeout; hot loop = timeout) and is still simpler than the alternative — one budget that spuriously kills programs for waiting on a slow tool. diff --git a/docs/rfc/proposed/feature/2026-06-15-optional-code-mode.md b/docs/rfc/proposed/feature/2026-06-15-optional-code-mode.md deleted file mode 100644 index e221618ce1..0000000000 --- a/docs/rfc/proposed/feature/2026-06-15-optional-code-mode.md +++ /dev/null @@ -1,119 +0,0 @@ -# RFC: Optional Code Mode — model writes TypeScript against an SDK of all tools - -Status: proposed - -> Premise partially stale: this proposal predates [request reconstructability](../../implemented/architecture/2026-07-05-reconstructable-requests.md) — `agent/request` now shapes call config only (no request/content mutation), so the interception points named below need re-mapping onto the log channels and `system-prompt/assemble` before implementation. - -## Problem - -Today the agent loop advertises every registered tool to the model as a native JSON-schema function definition. `ToolRegistry` feeds its schemas into `ctx.systemPrompt`, the loop puts them on `GenerateOptions.tools`, and the adapter serializes them to the provider's function-calling wire format. The model then invokes one `tool-call` block per step, the loop dispatches each call through `ctx.tools.execute()` **sequentially** (parallel tool execution is an explicit open TODO in `dsh-tools` and [docs/architecture.md](../../../architecture.md)), and **every** intermediate `tool-result` re-enters the model's context on the next request. - -For multi-step tool work this is token-heavy and serial. 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 of those round-trips 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/) (shipped as the `@cloudflare/codemode` npm package) 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 SDK that wraps all the tools, and that program is executed. The model curates what comes back — only what it `console.log`s and/or returns — instead of every intermediate result. The SDK functions are async, so the model can *express* fan-out (`Promise.all`) naturally in code; this RFC initially **serializes** those dispatches (§ Concurrency) until the tool contract grows concurrency-safety metadata, so the early win is composition and fewer round-trips, not parallelism. - -This RFC proposes an **optional** Code Mode for the DeepSeek Harness, covering **all** tools uniformly — built-in and future MCP — with no per-tool work, implemented Cordis-style with **zero core-package changes**. It fully specifies the code-execution seam and the SDK-generation pipeline, but ships only a minimal `node:vm` reference stub for execution; the hardened, sandboxed execution substrate is **deferred to a follow-up RFC** (see Risks). This RFC does not change the agent loop, and it leaves native tool-calling exactly as it is — Code Mode is a plugin you load, not a replacement. - -## Proposal - -The design follows the codebase's capability-seam pattern ([capability seams](../../implemented/architecture/2026-06-13-capability-seams.md), the `bash` template) as a three-package split, plus one consumer plugin. Nothing in `dsh-session`, `dsh-agent`, `dsh-agent-loop`, `dsh-llm`, `dsh-tools`, or `dsh-system-prompt` changes. - -**Prior art.** `@cloudflare/codemode` validates this shape directly and several of its decisions are adopted below. Its `Executor` interface is deliberately tiny — `execute(code, fns) → { result, error?, logs? }` — with a production `DynamicWorkerExecutor` (isolated Workers) and a six-line `NodeVMExecutor` example as two implementations behind it: exactly the interface/implementation split [the capability-seam pattern](../../implemented/architecture/2026-06-13-capability-seams.md) prescribes. It generates TypeScript type definitions from tools for the model's context and runs the generated JavaScript in a sandbox, capturing console output alongside the return value. It normalizes model output into an async arrow function via AST parsing (acorn) and sanitizes tool names into valid JS identifiers (`my-tool` → `my_tool`, `delete` → `delete_`). It blocks outbound network by default. The transferable lessons — minimal executor contract, host-side type derivation, capture-output-and-return-value, name sanitization, AST-normalize the code, isolate by default — are folded into the design below. What does **not** transfer is the substrate: Cloudflare's isolation is Workers-specific; our equivalent hardened substrate is the deferred follow-up. - -**Prompt-budget tradeoff (Code Mode is not unconditionally cheaper).** Deriving the SDK types host-side costs no extra *discovery* round-trip, but the generated `.d.ts` is injected into the system prompt (§3a), so the type definitions themselves **do** consume context — and for an all-tools SDK that cost scales with every registered tool and can be comparable to, or larger than, the native JSON schemas it replaces. Code Mode's saving is on the **output/result** side (the model curates what comes back; intermediate results never re-enter context) and on **round-trips** (compose many calls in one program), not on the input-side tool description. The net win is workload-dependent: it pays off for multi-call, large-intermediate-result workflows and can cost *more* for a single call against a large tool surface. The `.d.ts` section is a prefix-stable prompt prefix, so prompt caching amortizes its per-turn cost across a session; the RFC notes that caching is what keeps the injected SDK affordable, and that a deployment with a very large tool surface should weigh the SDK size against native schemas rather than assume Code Mode is strictly cheaper. - -**1. Interface package `packages/code-runtime/`** — a new package `@deepseek-ai/dsh-code-runtime` owning `ctx.codeRuntime`, depending only on `cordis`. It defines an abstract `CodeRuntime extends Service` plus the execution vocabulary. The runtime knows **nothing** about `ctx.tools`: it is handed a set of named async functions (the resolved SDK bindings), runs the program, and captures output. The result shape mirrors Cloudflare's proven-minimal contract so an error is a *field on a resolved result*, not a throw the runtime is expected to make: - -- `CodeRunRequest = { code: string; sdk: SdkBinding[]; signal?: AbortSignal }` -- `CodeRunResult = { result: unknown; logs: string[]; error?: string }` -- a readonly `safe: boolean` on the `CodeRuntime` service — `false` for an unsandboxed stub, `true` only for a real isolating substrate; consumers gate on it (§2). -- `SdkBinding = { namespace: string; fns: Record Promise> }` - -Per the "explicit > implicit at seams" convention, the request spells out every field the runtime acts on; defaulting (e.g. an output cap, a timeout derived from `signal`) is the implementation's explicit job, not a hidden `?? default` inside `run()`. The split into interface + implementation is justified under [the capability-seam pattern](../../implemented/architecture/2026-06-13-capability-seams.md) because there is **genuinely more than one planned implementation** — the node:vm stub *and* the hardened substrate (a real isolate, or the generated program run as a sandboxed process through the existing `ctx.bash` seam) that is scheduled follow-up work, not speculative optionality. The capability-seam pattern warns against splitting preemptively when only one implementation is conceivable; here a second is not just conceivable but required before any untrusted use, so the seam earns its keep. - -**Backends can differ by language/runtime, not only by trust level.** The two implementations above (unsafe stub vs. hardened substrate) differ along the *trust* axis while staying TypeScript/JS, but nothing in the `CodeRuntime` contract — a program string plus a set of named async SDK bindings in, and a `{ result, logs, error? }` out — is bound to one source language. The same seam can host backends that differ along the *language* axis, executing a program written in something other than TypeScript. Two illustrative directions: - -- **An AssemblyScript backend.** AssemblyScript is a strict TypeScript subset that compiles to WebAssembly, so a program stays familiar to a TS-fluent model while the WASM boundary supplies exactly the sandboxing the hardened substrate is meant to provide — memory isolation and no ambient host authority come from the runtime rather than from after-the-fact hardening of `node:vm`. This is an appealing route to a `safe = true` backend. -- **A Python backend.** Python is arguably the model's most native language — it has seen far more real Python than any tool-calling trace — which is the same "LLMs write better code than tool calls" argument that motivates Code Mode, taken one step further. A Python backend is itself a sub-seam over different Python *runtimes*: **CPython** (in-process or a sandboxed subprocess via `ctx.bash`) for maximum fidelity and ecosystem access, or a more controllable / embeddable interpreter — Pyodide (CPython on WASM), RustPython, or a restricted embedded interpreter — when isolation, deterministic resource limits, or a clean capability boundary matter more than running arbitrary native extensions. - -These are illustrations of the seam's reach, **not commitments** — the MVP ships only the TypeScript path. The honest caveat is that the *execution* contract is language-agnostic but the *presentation* is not: the SDK-generation pipeline below (§3a and the `jsonSchemaToTs` codegen, which emits a TypeScript `.d.ts`) is TypeScript-specific, so a non-TS backend pairs the shared `CodeRuntime` contract with its own language-appropriate SDK generator and system-prompt section (a `.pyi` stub and Python usage instructions for the Python backend, AssemblyScript-flavored types for that one). The runtime seam is reused as-is; only the codegen/prompt half is per-language. - -**2. Implementation package `packages/code-runtime-vm/`** — a new package `@deepseek-ai/dsh-code-runtime-vm`, the `node:vm` reference stub. It type-erases the model's TypeScript via the compiler's `transpileModule` (or sucrase) — the types exist only to guide the model; the runtime is plain JS — then wraps the body in an async IIFE for top-level `await` (Cloudflare's `NodeVMExecutor` does literally `new AsyncFunction("codemode", "return await (${code})()")`), runs it in a `vm.Context` whose globals are a capturing `console` and the SDK namespace objects, awaits the IIFE, and captures the return value, the buffered logs, and any thrown error (as `error: string`). It applies an **output cap** (truncate captured logs) and a **timeout tied to `request.signal`**. These caps limit blast radius; **they are not a security boundary**. node:vm is **not** isolation: withholding `require`/`process` does not contain anything (code escapes via `constructor`/prototype reflection), and per [AGENTS.md](../../../../AGENTS.md) the harness must never hand model output the ambient environment. - -**The unsafe-runtime guard is enforceable, not a README warning.** Because a README caveat is not a control — and AGENTS.md's "never hand model output ambient authority" is a hard rule, not advice — the design makes the danger refuse to run by construction. Two layers: - -- **The runtime declares its trust level.** `CodeRuntime` carries a readonly `safe: boolean` (a `node:vm`-class stub returns `safe = false`; a real isolate/sandboxed-process substrate returns `safe = true`). The `code-runtime-vm` constructor *additionally* requires an explicit opt-in — `new VmCodeRuntime({ unsafe: true })` — and **throws** if that flag is absent, so merely depending on the package and wiring it cannot silently produce a live unsafe runtime; the operator must type the word `unsafe`. -- **The consumer refuses to expose `run_code` over an unsafe runtime by default.** When `code-mode` initializes, if `ctx.codeRuntime.safe === false` it does **not** register `run_code` unless the plugin itself is configured with an explicit acknowledgement (e.g. `code-mode` config `allowUnsafeRuntime: true`). Absent that, it logs a typed error and registers nothing — so a real model never reaches an unsandboxed runtime by a single config slip. The refusal path is tested: with the acknowledgement unset and an unsafe runtime, `run_code` is absent (and the wire tool list is unchanged from native); with both opt-ins set, it registers and runs. This keeps the unsafe reference backend usable for tests and trusted local demos while making production misuse take two deliberate, greppable flags rather than one mistake. - -`code-runtime-vm` is therefore documented as **reference / test-only / unsafe-for-untrusted-input**, acceptable in the MVP only because the code runs at harness trust *and* both opt-in flags must be set. Signal handling is best-effort: it aborts in-flight sub-dispatches but cannot reliably interrupt a hot synchronous loop (`while(true){}`) in node:vm — another reason the hardened substrate is deferred, not optional-forever. - -**3. Consumer plugin `packages/code-mode/`** — a new package `@deepseek-ai/dsh-code-mode`, the plugin that wires everything together. It declares `inject = ['tools', 'systemPrompt', 'codeRuntime']` — Cordis throws on access to a service that is not injected, and keeps the plugin inactive until all three exist (the same pattern as `tool-bash`'s `inject = ['tools', 'bash']`), which also gives correct load-ordering relative to `code-runtime`/`code-runtime-vm`. The plugin contributes four things, all through existing seams: - -**3a. Tool presentation — a lazy system-prompt section (the injection seam already exists).** `dsh-system-prompt` already provides the Cordis-idiomatic way for any plugin to inject prompt snippets: `ctx.systemPrompt.section({ name, order, text })`, fiber-scoped and auto-disposed via `ctx.effect()`, where `text` may be a lazy `() => string` re-evaluated at each assembly. No new mechanism is needed or invented. Code Mode registers a lazy section (high `order` so it lands last) whose thunk reads `ctx.tools.schemas()` at assembly time and regenerates the SDK `.d.ts` plus usage instructions from the currently-registered tool set. Because the thunk reads the live registry, coverage of every tool — built-in, MCP, future — is automatic. - -**3b. Wire tool-list enforcement — an `agent/request` listener (the authoritative seam).** The goal "exactly one tool reaches the wire" must be enforced where the wire request is finalized. The loop calls `ctx.systemPrompt.assemble()` first, *then* builds `GenerateOptions` (seeding `tools` from `assembly.tools`), *then* runs the `agent/request` waterfall, *then* calls `ctx.llm.stream()`. A `system-prompt/assemble` listener can only influence the *seed*; `agent/request` is the last seam before the model call, so it is authoritative. The plugin registers an `agent/request` listener that does `const final = await next(); return { ...final, tools: [runCodeSchema] }` — overriding the value *returned by* `next()`, not the inbound argument, so it dominates the cooperative request listeners it wraps. It registers with `prepend: true` to sit at the outer edge of the waterfall chain. One honest caveat, stated in the RFC body: `ctx.llm.stream()` itself runs a further `llm/stream` waterfall before the adapter, so the guarantee is "authoritative within the agent request pipeline," not an absolute wire invariant; if a hard invariant is ever required, a defensive `llm/stream` assertion with a spy adapter covers it in tests. - -**3c. The single tool — `run_code`.** Registered normally in `ctx.tools` with one parameter `{ code: string (required) }`. Because it is an ordinary tool, the unchanged loop dispatches it through the normal path — this is the crux of "zero loop changes." Its `execute(args, exec)`: - -1. Builds the SDK bindings. For each real tool, an async `invoke(callArgs)` that **checks `exec.signal?.aborted` (throwing if set) before and after** calling `ctx.tools.execute({ callId: , name, arguments: callArgs, agent: exec.agent, signal: exec.signal })`, then maps the resulting `ContentBlock[]` to a simplified `{ output, isError }` (text blocks for the MVP), and emits an observability event. The explicit abort check matters because `ctx.tools.execute()` *catches* thrown tool errors and converts them to `isError` results — without the check, an aborted sub-call would look like ordinary error data and the program would keep running instead of stopping. Sub-dispatch still flows through the `tools/pre-execute`/`tools/post-execute` waterfalls, so permission/sandbox/hook plugins apply to code-mode calls exactly as to native ones. -2. Calls `ctx.codeRuntime.run({ code: args.code, sdk: bindings, signal: exec.signal })`. -3. Surfaces the outcome. A *successful* run returns `[{ type: 'text', text: }]`. A *runtime-error* result cannot be reported by returning content, because a normal `ToolDefinition.execute()` returns only `Promise` and `ToolRegistry.execute()` hardcodes `isError: false` on any successful return — `isError: true` arises only from the registry's catch path. So on an error result the tool **throws a `CodeRunError extends HarnessError`** (`HarnessError` is exported from `dsh-llm`; the registry catch turns any throw into `isError: true` with the message as text, and a `HarnessError` additionally carries structured `{ name, code }`). An alternative — registering `run_code` handling as a `tools/execute` listener that returns a full `ToolExecutionResult` and can set `isError` directly — is noted; the throw is simpler and preferred. - -**3d. Result discipline — what the model receives.** The model gets back **only the captured console output and/or the program's return value** (the model chooses which to surface). Intermediate sub-call results are **never** returned to the model. This is the core context-saving benefit: the agent curates its own output, exactly as a script's stdout curates a pipeline's intermediate state. - -**Sub-call CallIds.** Real tool calls dispatched from inside `run_code` need ids, but `CallId` is normally provider-issued (a branded string for correlating a call with its result — only brand-wrapped via `CallId()`, with no generator and no documented session-global-uniqueness guarantee). The plugin mints deterministic sub-ids scoped to the parent: `` `${exec.callId}:code:${n}` `` with a per-run counter `n`. These are unique within one `run_code` run (assuming the parent `callId` is unique, which the provider guarantees per turn); the `code/dispatch` event additionally carries the session log's `seq` so the UI and persistence can order and disambiguate globally without relying on the id alone. `ToolExecution.agent` is optional; the normal loop always supplies it (and with it `exec.agent.session`, the log `code/dispatch` appends to). A `run_code` execution arriving without `exec.agent` still runs (sub-calls propagate `agent: undefined`, exactly as the loop's own contract allows) but **skips session-log observability** — with no session to append to, those direct runs are simply not logged. - -**Observability without context cost.** Each sub-dispatch emits a session event **declared by the `dsh-code-mode` plugin itself** via `SessionEventMap` declaration merging (the map is merge-extensible precisely so plugins can add events without touching `dsh-session`). Shape: `code/dispatch` with `{ parentCallId, subCallId, name, arguments (or redacted), isError, summary }`, ordered by the session log's own `seq`. `deriveMessages()` does **not** translate it into a model message — an unknown event type falls through its `default`, per the merge-extensible-union convention — so the UI and persistence ([session persistence](../../implemented/architecture/2026-06-14-session-persistence.md)) can render every sub-call while the model's context only ever receives the single `run_code` tool-result. Because the event lives in the plugin, this adds no core change. - -**SDK codegen.** A pure `jsonSchemaToTs(schema)` in `code-mode` maps the JSON-schema subset the `defineTool` DSL produces (object/string/number/boolean/array, `properties`, `required[]`, `enum` → string-literal union, nested objects, array `items`) to a TS type literal. It is **total**: any unsupported construct (`$ref`, `oneOf`/`anyOf`, `integer`, `null`, `additionalProperties`, or any raw MCP shape it does not recognize) degrades to `unknown` without throwing — it never crashes codegen. Typing is best-effort, not a guarantee, because MCP tools accept arbitrary JSON Schema and `ToolSchema.parameters` is typed only as `Record`. Because `ToolSchema.name` is an arbitrary string (not necessarily a valid TS identifier), the SDK is generated as a **namespace with quoted access** (e.g. `tools["some-mcp-tool"](args)`) plus safe camelCase aliases where the name is a clean identifier; alias collisions and TS reserved words fall back to quoted-only access (no duplicate alias emitted). This mirrors Cloudflare's `sanitizeToolName`. `run_code` itself is filtered out of the SDK. The MVP surfaces text content only; image and other block types in sub-results are deferred (noted as a limitation). - -**Concurrency — serialized by default (the binding must enforce it).** The SDK functions are async, so a model writing `await Promise.all([tools.a(...), tools.b(...)])` would *start both* immediately, and each would call `ctx.tools.execute` right away — i.e. the binding shape makes concurrent dispatch the **default**, not an opt-in. Because the tool contract carries **no concurrency-safety metadata today** (parallel tool execution and a concurrency-safety hint are an open TODO in both `dsh-tools` and [docs/architecture.md](../../../architecture.md): "phase 1 executes tool calls sequentially"), concurrent dispatch through a not-yet-hardened tool may race. So a prose "may serialize" is not sufficient. **Decision: the MVP SDK bindings enforce serialization** — each `run_code` invocation owns a per-run dispatch queue, and every `invoke()` chains onto it (`tail = tail.then(() => ctx.tools.execute(...))`), so even `Promise.all` over SDK calls executes them one at a time in submission order. This is a hard acceptance criterion, with a test that issues `Promise.all([...])` from a program and asserts the underlying `ctx.tools.execute` calls did **not** overlap (e.g. a probe tool records enter/exit and the test asserts no interleaving). The `.d.ts` may *describe* the model-visible functions as async (they are), but the implementation guarantees serial execution. Lifting serialization is deferred: only once a tool can declare itself read-only / concurrency-safe does the binding allow those specific tools to overlap. The same per-run queue is where the before/after abort checks (§3c) live, so an aborted run drains no further queued dispatches. - -**Tool visibility tiers (design intentionally skipped).** A natural extension is to mark each tool with a *visibility tier*: some tools "direct-call eligible" (still offered as native wire tools alongside `run_code`), some "code-mode only" (reachable solely from within a `run_code` program, never on the wire), and the default "both." This would let a deployment keep a few high-frequency or approval-gated tools as direct calls while routing the long tail through Code Mode, or hide composition-only primitives from the native surface entirely. This RFC notes the possibility but **intentionally skips the detailed design** — the per-tool metadata, how it interacts with the `agent/request` enforcement in 3b, and the presentation split in 3a are left to a follow-up. The MVP is the simple two-state model: Code Mode on (everything via `run_code`) or off (everything native). - -**Optionality / toggle.** Loading the `code-mode` plugin enables Code Mode for that context; not loading it leaves today's native tool-calling untouched. The two are mutually exclusive within one ctx, because Code Mode rewrites the wire tool list down to `[run_code]`. Per-agent selection via ctx forks, and the visibility tiers above, are future work; the MVP toggle is plugin presence. - -## Alternatives considered - -**Result elision / summarization over native tool-calling (the narrower route).** The Problem has two halves — context bloat (every intermediate `tool-result` re-enters context) and serial composition (one tool call per round-trip). The context-bloat half can be addressed *without* any code-execution runtime: keep provider tool-calling exactly as it is, and add a plugin on the `agent/request` waterfall (or a compaction pass akin to [the session-persistence work](../../implemented/architecture/2026-06-14-session-persistence.md)) that elides or summarizes older `tool-result` blocks before they re-enter the model's context — drop them past a window, replace large payloads with a digest, or keep only the blocks the model still references. This is strictly less invasive than Code Mode: no new runtime seam, no model-written programs, no new safety surface. It is the right tool if context growth is the only pain. - -It is insufficient for the **composition / round-trip** half, which is the decisive reason this RFC does not stop there. Elision still pays one model round-trip per tool call: a loop over N items is N turns, a branch on an intermediate value is a turn to fetch then a turn to act, and post-processing (filter, join, reduce) either happens in the model's head over full payloads or not at all. Code Mode collapses all of that into one program — the loop, the branch, the join run in the runtime, and only the curated result returns. Elision also cannot express fan-out or data-dependent control flow; it only shrinks what comes back. So the two are complementary, not competing: elision could even layer *under* Code Mode for the residual native-tool paths. The RFC chooses Code Mode because the round-trip/composition cost is the larger structural limit, and accepts the new code-execution surface as the price — which is exactly why the execution substrate is gated behind the enforceable safety guard (§2) and the hardened backend is a hard prerequisite for untrusted use. - -**Why not change the loop to dispatch native tool calls in parallel instead?** That is the other obvious answer to the round-trip cost, and it remains valid future work (it is the open `dsh-tools`/architecture.md TODO). But it is a core-loop change requiring the same concurrency-safety metadata Code Mode defers, and it still does not give the model *composition* (branch/loop/post-process between calls) — only parallelism of independent calls the model already decided to make in one step. Code Mode delivers composition with zero core change; parallel native dispatch and Code Mode can coexist later. - -## Plan - -1. Scaffold the interface package `packages/code-runtime/` per [the cookbook](../../../cookbook/adding-a-package.md): abstract `CodeRuntime extends Service` (`super(ctx, 'codeRuntime')`) with a readonly `safe: boolean`, the `declare module 'cordis'` ctx key, the `CodeRunRequest`/`CodeRunResult`/`SdkBinding` vocabulary, method contracts documented in JSDoc (what `run` captures, abort semantics, that an error is a result field not a throw, what `safe` means). HMR-safety test (dispose the contributing fiber, assert `ctx.codeRuntime` is gone). -2. Scaffold the implementation package `packages/code-runtime-vm/`: the node:vm stub — `safe = false`, a constructor that **throws unless given `{ unsafe: true }`**, transpile/type-erase, async-IIFE wrap, capturing `console`, SDK globals, return-value/logs/error capture, output cap, signal-tied timeout. Tests for output capture, return value, error-as-field, abort, the constructor refusal without `unsafe`, and a README documenting the "not a sandbox, trusted-only" caveat prominently. -3. Scaffold the consumer plugin `packages/code-mode/`: `jsonSchemaToTs` codegen with namespace/quoted-access + alias handling (unit tests, including non-identifier MCP names and unsupported-shape → `unknown`); the registered lazy `ctx.systemPrompt.section()` carrying the SDK `.d.ts`; the `agent/request` listener (`prepend: true`) collapsing `request.tools` to `[run_code]` after `await next()`; the **unsafe-runtime gate** (refuse to register `run_code` when `ctx.codeRuntime.safe === false` unless `allowUnsafeRuntime` is set); the `run_code` tool with the dispatch bridge (per-run serialization queue, deterministic sub-call ids, before/after abort checks, `CodeRunError` on error results); and the `code/dispatch` event declared here via `SessionEventMap` merge. Declare `inject = ['tools', 'systemPrompt', 'codeRuntime']`. -4. Tests: HMR-safety (dispose removes the tool, the section, and the listener); a waterfall test that the wire tool list is exactly `[run_code]` (spy adapter, asserting via `agent/request` and optionally `llm/stream`); an integration test that a program calling two tools returns only its printed/returned output (verify the world, not the self-report); a **serialization test** that `Promise.all([...])` over SDK calls does not overlap the underlying `ctx.tools.execute` invocations (a probe tool records enter/exit; assert no interleaving); `deriveMessages()` ignores `code/dispatch`; abort mid-program stops further dispatches; `CodeRunError` surfaces as `isError: true`; and the **unsafe-runtime refusal test** (§3, the VM-guard): with the unsafe flag unset, a non-mock agent's `run_code` is refused; with it set, the program runs. -5. Wire an example: `examples/coding-agent-code-mode` (or a config flag on the existing example) loading the trio. Running it against the node:vm stub requires both opt-ins (`VmCodeRuntime({ unsafe: true })` and `code-mode`'s `allowUnsafeRuntime`); the example sets them explicitly and comments why, or uses a mock model — a real model never reaches the unsandboxed stub without those deliberate flags. Add a `pnpm run demo:*` entry. -6. Docs: update [docs/architecture.md](../../../architecture.md) (a `ctx.codeRuntime` row in the service map, a Code Mode note under the tool pipeline / capability seams sections); add a [cookbook](../../../cookbook) note on writing a `CodeRuntime` backend; and **file the follow-up RFC for the hardened execution substrate** (the isolate/sandboxed-process design, the additional-language backends sketched in §1 — AssemblyScript/WASM, Python — with their per-language SDK generators, plus the tool-visibility-tier design skipped here). On landing, move this file to `implemented/` and update its row in [the RFC index](../../README.md). - -## Acceptance criteria - -- The three packages exist and pass their suites: `dsh-code-runtime` (the abstract seam), `dsh-code-runtime-vm` (the reference stub whose constructor throws without `{ unsafe: true }`), and `dsh-code-mode` (SDK codegen, the lazy prompt section, the `agent/request` collapse, the `run_code` tool). -- The wire tool list is exactly `[run_code]` under the plugin (spy-adapter test); the generated SDK covers every registered tool, with non-identifier names reachable via quoted access. -- A program calling two tools returns only its curated output; `code/dispatch` events land in the session log and never enter derived history. -- `Promise.all` over SDK calls does not overlap the underlying `ctx.tools.execute` invocations (the per-run serialization queue holds); an abort stops further dispatches. -- With `allowUnsafeRuntime` unset over an unsafe runtime, `run_code` is not registered and the wire tool list is unchanged from native. - -## Risks - -node:vm is not a sandbox. This is the single biggest caveat. Withholding `require`/`process` is not a boundary; the MVP runs at harness trust only; the hardened substrate is a hard prerequisite before any untrusted use and is the explicit subject of a follow-up RFC. The guard is enforceable, not just documented: the runtime exposes `safe: boolean`, the VM stub throws unless constructed with `{ unsafe: true }`, and `code-mode` refuses to register `run_code` over an unsafe runtime unless separately acknowledged (`allowUnsafeRuntime`) — production misuse requires two deliberate, greppable flags, and the refusal path is tested. - -Wrong seam would leak tools. If the wire tool list were enforced only in `system-prompt/assemble`, a later `agent/request` listener could re-add tools. Mitigation: enforce `request.tools = [run_code]` in the `agent/request` waterfall (the authoritative seam, run last before `llm.stream()`) with `prepend: true`, and assert exactly one wire tool in tests. The residual `llm/stream` caveat is documented, not hidden. - -Concurrency before the contract supports it. The binding shape makes concurrent dispatch the default, and the tool contract has no concurrency-safety metadata yet, so unguarded `Promise.all` over SDK calls could race a not-yet-hardened tool. Mitigation: the MVP bindings enforce a per-run serialization queue (every `invoke` chains onto the previous), with a test asserting `Promise.all` from a program does not overlap the underlying `ctx.tools.execute` calls. Per-tool parallelism is unlocked only once a tool can declare itself concurrency-safe. - -Two presentation modes to keep coherent. A tool added later must work in both native and Code Mode. Mitigation: both the codegen thunk and the `agent/request` listener read `ctx.tools.schemas()`, so coverage is automatic; a test asserts every registered schema produces valid `.d.ts`, including non-identifier MCP names via quoted access. - -Type-erased runtime is not type-checked. The model can write code that type-checks against the advisory `.d.ts` but throws at runtime, and MCP-schema typing is best-effort. Mitigation: errors are captured as `CodeRunResult.error` and surfaced so the model can self-correct; the `.d.ts` is explicitly advisory. - -Lost observability of sub-calls. Routing everything through one `run_code` result hides the individual calls from the model — and could hide them from operators too. Mitigation: the plugin-declared `code/dispatch` event keeps every sub-call in the session log and UI without polluting model context. - -Abort granularity. node:vm cannot reliably interrupt hot synchronous code, and `ctx.tools.execute()` converts thrown aborts into `isError` data. Mitigation: the SDK bindings check `signal.aborted` and throw before/after each dispatch so an aborted sub-call stops the program; the vm stub wraps the run in a signal-tied timeout; the hardened substrate addresses the hot-loop case. - -Unsafe example wiring. A demo running a real model through the node:vm stub would hand model output ambient authority. Mitigation: examples are mock-model or explicitly marked unsafe; `code-runtime-vm` is labeled reference/test-only. - -Non-text sub-results dropped in the MVP. Image and other block types from sub-calls are not surfaced into the program yet. Mitigation: noted as a known limitation; block-type handling deferred.

A run with `result.error` throws a `CodeRunFailedError extends HarnessError` (`code: 'CODE_RUN_FAILED'`, message = the error kind and text plus captured logs so the model can self-correct); the registry's existing catch turns it into a structured `isError` result. +**Sub-call `additionalContext` is suppressed, deliberately.** A `tools/post-execute` hook may attach `additionalContext` to a call; for loop-dispatched calls the loop buffers those and appends each as a `context/message` only after the step's `tool/result`s, preserving call/result adjacency. A sub-dispatch result's `additionalContext` has no such safe outlet from inside a running `run_code`: injecting immediately would land a `context/message` between the parent's `tool/call` and its `tool/result` (breaking the adjacency the buffering exists to protect), and `PostToolDecision.additionalContext` is singular where a program may produce many. The MVP therefore drops sub-call `additionalContext`, pinned by a test and stated in the hooks bridge's docs; the follow-up (a plural context channel or loop-level sub-dispatch buffering) is deferred until a real hook needs it through Code Mode. + **Concurrency: serialized, enforced by the binding.** The bindings are async, so a model writing `Promise.all([tools.a(…), tools.b(…)])` starts both immediately — concurrent dispatch would be the *default*, while the tool contract still carries no concurrency-safety metadata (the open parallel-execution TODO). Each `run_code` invocation therefore owns a dispatch queue and every binding call chains onto it, so even `Promise.all` executes the underlying `ctx.tools.execute()` calls one at a time in submission order; when the run settles, queued-but-unstarted dispatches are abandoned.

Measured busy time cannot be gamed: a hot loop accrues it whether or not a dispatch is in flight, and a program genuinely awaiting a slow tool accrues none, so a long-running `bash` sub-call still does not kill an innocent run. The wall ceiling (`maxWallMs`) never pauses for anything and backstops what busy-time cannot see (a program awaiting a promise nobody will resolve). Budget expiry, `signal` abort, and run completion all funnel into `worker.terminate()`, which ends hot synchronous loops too (measured; this was `node:vm`'s unfixable gap); the failure reports which budget fired.

The spawn/client glue is already triplicated across [acp.e2e.ts](../../../../examples/acp-agent/tests/acp.e2e.ts), [hooks.e2e.ts](../../../../examples/acp-agent/tests/hooks.e2e.ts), and the harness, marked by `TODO(acp-test-harness)`. + +Location also decides test rigor: the per-file 100% coverage gate measures `packages/*/*/src` only, so none of this machinery is measured — the same gap that moved `dsh-llm-replay` out of `examples/` into [packages/support](../../../../packages/support/README.md). The harness's subprocess lifecycle, teardown, and harvest-ordering branches are exercised only transitively, when a live scenario happens to hit them. + +Finally, the harness's ACP client hardcodes `requestPermission → cancelled`, so an approval round-trip — the headline behavior of the sandbox composition — cannot be expressed at the snapshot tier at all. A new transcript surface must name its coverage at every tier at plan time; today the tier cannot express this one. + +## Proposal + +Create `packages/support/acp-snapshot` (`@deepseek-ai/dsh-acp-snapshot`), a support-tier package with three source modules; each example keeps only its scenario table, its `snapshots/` fixtures, its `cordis.snapshot.yml` overlay ([single-source replay config](../../implemented/testing/2026-07-04-single-source-acp-replay-config.md)), and the paths that identify its agent. + +**`src/harness.ts`** — `runScenario` and the input-script/result types, moved intact, with the module-level path constants replaced by an explicit `AgentUnderTest` parameter (`binScript`, `configPath`, `tsconfigPath`): defaulting stays at the seam's consumer, which resolves them from its own `import.meta.url`. The internal spawn/tee/SDK-client wiring is factored so the e2e launcher duplication can migrate onto it later; that migration is out of scope here and the `TODO(acp-test-harness)` stays until it lands. + +**`src/normalize.ts`** — the normalizers move verbatim with their spec. They stay hook-free: when a future event carries a new volatile field (an approval duration, say), the shared normalizer learns it in the same change, keeping one home for what "normalized" means rather than per-suite scrub extensions. + +**`src/suite.ts`** — the `Scenario` type and `defineAcpSnapshotSuite(options)`, which registers the per-scenario `describe`/`it` tree and the fixture guard tests. Options carry the resolved `mode: 'replay' | 'record'` — reading `DSH_SNAPSHOT` stays at the edge, in the example's `*.snapshot.ts`. The guard logic (no orphan scenario dirs, required fixture files, exactly one pin, non-pinning fixtures are `scrubRequestHeaders` fixed points) is exported as pure assertion functions the registered tests call one-line-each, so failure paths are unit-testable without meta-running vitest. The pinned-header contract ([pinned-header RFC](../../implemented/testing/2026-07-06-pin-request-header-content-in-one-scenario.md)) becomes per-suite: each suite flags exactly one `pinsHeader` scenario and its uniformity guard compares only that suite's sessions, which is the guard's existing scope. + +**Scripted permission answers** — `InputScript` gains an optional ordered `permissionAnswers` queue consumed by the harness client's `requestPermission`, each entry selecting a response by option **kind** (`allow_once`, `reject_once`, …); the harness maps kind to the agent-issued `optionId` at answer time, since ids are random per run while kinds are stable. An exhausted or absent queue falls back to today's `cancelled`, so existing scenarios and goldens are untouched. This is what lets a sandbox suite script an approval round-trip deterministically from `input.json`. + +Repo wiring follows the [adding-a-package cookbook](../../../cookbook/adding-a-package.md): manifest per the workspace constraints (cordis peer+dev, `private`, standard `files`), references in the root and build tsconfigs (the `@deepseek-ai/dsh-*` paths wildcard already covers `packages/support/*/src`), a row in the support group README, and explicit `@agentclientprotocol/sdk`/`vitest`/`tsx` dependencies instead of inherited-by-walk-up resolution. [docs/testing.md](../../../testing.md) generalizes "scenarios live under `examples/acp-agent/tests/snapshots/`" to the owning example's `tests/snapshots/`. + +Landing order is three commits on one PR: (1) the pure move plus parameterization, with `examples/acp-agent/tests/acp.snapshot.ts` collapsed to its scenario table and one `defineAcpSnapshotSuite` call; (2) the coverage work — a scripted fake ACP bin fixture (reads JSON-RPC frames on stdin, emits canned responses and session updates, writes synthetic session JSONL under `DSH_SNAPSHOT_SESSIONS_ROOT`) driving `harness.ts` through every step op, expect-error branch, child-harvest ordering, and teardown path, and `suite.spec.ts` registering synthetic replay- and record-mode suites against temp fixture dirs (record mode is keyless here: the live API sits behind the bin, and the fake bin needs none); (3) `permissionAnswers` with its unit coverage. The sandbox branch then merges master down and adds its own suite: scenario table, own pin scenario, own overlay, fixtures recorded via `test:snapshot:record`. + +## Alternatives considered + +- **Copy the modules into each example** — the fork this RFC exists to prevent: the record/guard logic is exactly the code that must stay byte-identical across suites, and examples are outside the coverage gate, so each copy is also unmeasured. +- **A shared module directory under `examples/`** — keeps the code outside the coverage gate and forces relative imports across example boundaries, against the package-name import convention; `examples/` leaves stay thin by design. +- **A `/testing` subpath export of `dsh-acp-agent`** — couples test infrastructure into a product package's surface and dependency set; `packages/support/` exists precisely for real-but-lower-compatibility dev/test packages, with `dsh-llm-replay` as the precedent this proposal completes. +- **Export raw test-body functions instead of a suite factory** — each example would re-own the `describe`/`it` skeleton (~80 lines of registration boilerplate per suite) for no flexibility gain; the factory keeps consumers to a scenario table plus one call, and the pure guard functions preserve unit-testability inside the factory design. +- **An injectable ACP `Client` factory instead of declarative `permissionAnswers`** — maximally flexible, but it leaks SDK client construction to every consumer and reopens per-example drift in exactly the layer being unified; a declarative queue keeps `input.json` the single scripting surface and stays golden-normalizable. +- **Generalize beyond ACP (a transport-agnostic snapshot harness)** — no second transport exists; the harness is ACP-shaped end to end (SDK client, JSON-RPC frames, `session/update` waiters), and a speculative abstraction would be a seam split ahead of any consumer. + +## Acceptance criteria + +- After the pure-move commit, `pnpm run test:snapshot` is green with zero byte changes under `examples/acp-agent/tests/snapshots/` — the machine proof that extraction changed no behavior. +- `pnpm run test:coverage` holds the new package's `src/` at per-file 100% with keyless unit specs; any `v8 ignore` carries its reason. +- `examples/acp-agent/tests/acp.snapshot.ts` contains no golden/compare/guard logic — only the scenario table, the agent paths, and the factory call. +- A harness unit test drives a `permissionAnswers` script through kind→`optionId` mapping and the exhaustion fallback, demonstrating the tier can express an approval round-trip before the sandbox suite needs it. +- `doc-sync`, `hygiene`, and `verify-module-graph` pass with the new package wired in. + +## Risks + +- **Per-file 100% on `suite.ts`** is the tightest constraint: `toMatchFileSnapshot` update semantics differ under CI, and factory-registered tests must be driven by real vitest collection. The pure-guard-function split plus synthetic-suite registration is the mitigation; a justified `v8 ignore` is the last resort, not the plan. +- **`vitest` becomes a `src` dependency** of a workspace package (the factory imports `describe`/`it`/`expect`), so importing `suite.ts` outside a vitest run throws — acceptable for a support-tier package and stated in its README, but it is a shape no other package has. +- **Fake-bin drift**: harness unit tests exercise plumbing against a scripted bin, not the real one. The real bin path stays exercised on every `test:snapshot` run, so drift surfaces there; the fake bin only owns branches the live suite cannot deterministically reach. +- **Per-suite pins duplicate header bulk**: each new suite commits one full ~8 KB header fixture. Accepted — a suite whose composition equals another's is the degenerate case the uniformity guard would surface, and one pinned line per genuinely distinct composition is the pinned-header design applied at its natural scope. +- The extraction touches the gating snapshot suite itself; a subtle behavior change would surface as golden churn. The zero-byte-diff acceptance criterion is the guard. From 556f8470642218ad2235d73efe0511f1e1587289 Mon Sep 17 00:00:00 2001 From: kingwl Date: Wed, 8 Jul 2026 01:44:20 +0800 Subject: [PATCH 104/132] feat(acp-snapshot): extract the ACP snapshot suite into a support package MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The snapshot tier's machinery leaves examples/acp-agent/tests for packages/support/acp-snapshot (@deepseek-ai/dsh-acp-snapshot), where the coverage gate measures it and a second example can consume it instead of forking it: harness.ts (runScenario, parameterized by an AgentUnderTest {binScript, configPath, tsconfigPath} instead of module constants), normalize.ts (moved verbatim), and suite.ts (defineAcpSnapshotSuite — the per-scenario golden/log compares, record write-back, per-suite header pin with its uniformity guard, and the fixture guard block, lifted from acp.snapshot.ts). The example file collapses to its scenario table plus one factory call; env reading (DSH_SNAPSHOT) stays at that edge. The exactly-one-pin meta-test generalizes from the hardcoded text-turn name to "exactly one per suite" — which scenario pins is the scenario table's reviewable choice (per-suite pinning per the proposal RFC). Extraction parity: pnpm run test:snapshot is 36 passed + fs-policy-reject failing BEFORE AND AFTER (BSD-sed environment failure, reproduced at the base commit in a clean worktree — the recorded golden's sed -i syntax is GNU-only), with zero byte changes under examples/acp-agent/tests/snapshots/.

charset=UTF-8 Content-Transfer-Encoding: 8bit A scripted fake ACP agent bin (tests/fixtures/fake-acp-agent.ts) speaks real newline JSON-RPC through the REAL runScenario spawn path (tsx loader, temp cwd, env plumbing); every behavior — prompt outcome, session/new rejection, persisted logs, filesystem noise — comes from a behavior.json beside the fixture, so specs script whole subprocess runs from data. harness.spec.ts drives every step op, both expect-error arms, the permission-stub default, env forwarding, workspace seeding, and the harvest ordering/noise/fallback branches. suite.spec.ts runs the factory for real at collection time: a replay suite over committed synthetic fixtures and a record suite over a temp copy (write-back never touches the committed tree; ACP_SNAPSHOT_SPEC_BOOTSTRAP=1 re-bootstraps it), plus direct cases for the exported pure helpers. The suite factory's pure helpers (childFixturePaths, fixtureContext, normalizedHeaders, headerDeltaCount) are exported for those direct specs. Two branches carry justified v8 ignores, both structurally unreachable: the waiter in-bounds guard (noUncheckedIndexedAccess) and waitForExit's already-exited race guard (both call sites sit one synchronous frame after stdin.end()/kill()). The fake bin substitutes the session/new cwd, not process.cwd(), into scripted logs — the realpath difference (/private on darwin) is exactly what the real bin's header carries. packages/support/acp-snapshot/src is at 100% statements, branches, functions, and lines under the per-file gate. --- knip.json | 2 +- packages/support/acp-snapshot/src/harness.ts | 11 +-

The pinned-header contract ([pinned-header RFC](../../implemented/testing/2026-07-06-pin-request-header-content-in-one-scenario.md)) becomes per-suite: each suite flags exactly one `pinsHeader` scenario and its uniformity guard compares only that suite's sessions, which is the guard's existing scope. - -**Scripted permission answers** — `InputScript` gains an optional ordered `permissionAnswers` queue consumed by the harness client's `requestPermission`, each entry selecting a response by option **kind** (`allow_once`, `reject_once`, …); the harness maps kind to the agent-issued `optionId` at answer time, since ids are random per run while kinds are stable. An exhausted or absent queue falls back to today's `cancelled`, so existing scenarios and goldens are untouched. This is what lets a sandbox suite script an approval round-trip deterministically from `input.json`. - -Repo wiring follows the [adding-a-package cookbook](../../../cookbook/adding-a-package.md): manifest per the workspace constraints (cordis peer+dev, `private`, standard `files`), references in the root and build tsconfigs (the `@deepseek-ai/dsh-*` paths wildcard already covers `packages/support/*/src`), a row in the support group README, and explicit `@agentclientprotocol/sdk`/`vitest`/`tsx` dependencies instead of inherited-by-walk-up resolution. [docs/testing.md](../../../testing.md) generalizes "scenarios live under `examples/acp-agent/tests/snapshots/`" to the owning example's `tests/snapshots/`. - -Landing order is three commits on one PR: (1) the pure move plus parameterization, with `examples/acp-agent/tests/acp.snapshot.ts` collapsed to its scenario table and one `defineAcpSnapshotSuite` call; (2) the coverage work — a scripted fake ACP bin fixture (reads JSON-RPC frames on stdin, emits canned responses and session updates, writes synthetic session JSONL under `DSH_SNAPSHOT_SESSIONS_ROOT`) driving `harness.ts` through every step op, expect-error branch, child-harvest ordering, and teardown path, and `suite.spec.ts` registering synthetic replay- and record-mode suites against temp fixture dirs (record mode is keyless here: the live API sits behind the bin, and the fake bin needs none); (3) `permissionAnswers` with its unit coverage. The sandbox branch then merges master down and adds its own suite: scenario table, own pin scenario, own overlay, fixtures recorded via `test:snapshot:record`. - -## Alternatives considered - -- **Copy the modules into each example** — the fork this RFC exists to prevent: the record/guard logic is exactly the code that must stay byte-identical across suites, and examples are outside the coverage gate, so each copy is also unmeasured. -- **A shared module directory under `examples/`** — keeps the code outside the coverage gate and forces relative imports across example boundaries, against the package-name import convention; `examples/` leaves stay thin by design. -- **A `/testing` subpath export of `dsh-acp-agent`** — couples test infrastructure into a product package's surface and dependency set; `packages/support/` exists precisely for real-but-lower-compatibility dev/test packages, with `dsh-llm-replay` as the precedent this proposal completes. -- **Export raw test-body functions instead of a suite factory** — each example would re-own the `describe`/`it` skeleton (~80 lines of registration boilerplate per suite) for no flexibility gain; the factory keeps consumers to a scenario table plus one call, and the pure guard functions preserve unit-testability inside the factory design. -- **An injectable ACP `Client` factory instead of declarative `permissionAnswers`** — maximally flexible, but it leaks SDK client construction to every consumer and reopens per-example drift in exactly the layer being unified; a declarative queue keeps `input.json` the single scripting surface and stays golden-normalizable. -- **Generalize beyond ACP (a transport-agnostic snapshot harness)** — no second transport exists; the harness is ACP-shaped end to end (SDK client, JSON-RPC frames, `session/update` waiters), and a speculative abstraction would be a seam split ahead of any consumer. - -## Acceptance criteria - -- After the pure-move commit, `pnpm run test:snapshot` is green with zero byte changes under `examples/acp-agent/tests/snapshots/` — the machine proof that extraction changed no behavior. -- `pnpm run test:coverage` holds the new package's `src/` at per-file 100% with keyless unit specs; any `v8 ignore` carries its reason. -- `examples/acp-agent/tests/acp.snapshot.ts` contains no golden/compare/guard logic — only the scenario table, the agent paths, and the factory call. -- A harness unit test drives a `permissionAnswers` script through kind→`optionId` mapping and the exhaustion fallback, demonstrating the tier can express an approval round-trip before the sandbox suite needs it. -- `doc-sync`, `hygiene`, and `verify-module-graph` pass with the new package wired in. - -## Risks - -- **Per-file 100% on `suite.ts`** is the tightest constraint: `toMatchFileSnapshot` update semantics differ under CI, and factory-registered tests must be driven by real vitest collection. The pure-guard-function split plus synthetic-suite registration is the mitigation; a justified `v8 ignore` is the last resort, not the plan. -- **`vitest` becomes a `src` dependency** of a workspace package (the factory imports `describe`/`it`/`expect`), so importing `suite.ts` outside a vitest run throws — acceptable for a support-tier package and stated in its README, but it is a shape no other package has. -- **Fake-bin drift**: harness unit tests exercise plumbing against a scripted bin, not the real one. The real bin path stays exercised on every `test:snapshot` run, so drift surfaces there; the fake bin only owns branches the live suite cannot deterministically reach. -- **Per-suite pins duplicate header bulk**: each new suite commits one full ~8 KB header fixture. Accepted — a suite whose composition equals another's is the degenerate case the uniformity guard would surface, and one pinned line per genuinely distinct composition is the pinned-header design applied at its natural scope. -- The extraction touches the gating snapshot suite itself; a subtle behavior change would surface as golden churn. The zero-byte-diff acceptance criterion is the guard.

Add a tools/execute around-dispatch waterfall to dsh-tools whose base next() is the dispatch-with-normalization thunk, and a new @deepseek-ai/dsh-timeout-policy plugin (packages/timeout/) that arms a per-tool deadline on exec.signal and returns a structured TOOL_TIMEOUT when it wins.

A listener receives `(exec, next)`: it calls `next()` to delegate to dispatch (returning its result, optionally wrapped) or returns a replacement result to short-circuit dispatch. The whole pipeline still sits inside `execute`'s outer try/catch, so a throwing listener becomes an `isError` result, never a turn failure. + +That the catch is the base `next` — not something outside the waterfall — is load-bearing: when a provider sees the timeout signal and throws its own upstream-abort error, registry dispatch first converts it to a normal error result, and only then can `timeout-policy` replace the final result with `TOOL_TIMEOUT`. + +### The `timeout-policy` plugin + +The plugin is `@deepseek-ai/dsh-timeout-policy`, a function/namespace plugin (`name` / `Config` / `apply`) in the `packages/timeout/` group.

For a configured tool the listener arms `deadline(exec.signal, timeoutMs, 'TOOL_TIMEOUT')`, swaps the derived signal onto `exec` for the downstream dispatch, restores the caller's own signal afterward, and returns a structured `TOOL_TIMEOUT` result when `timeoutOf(d.signal, 'TOOL_TIMEOUT')` matches. An unconfigured tool delegates unchanged. + +Signal replacement is by **in-place mutation of `exec.signal`**, not by passing a new object to `next()`. Cordis's waterfall `next()` ignores any arguments handed to it and re-invokes downstream listeners with the shared payload array (`vendor/cordis/src/events.ts`), so the documented cordis idiom — mutate the shared object, then delegate — is the only mechanism that reaches dispatch. The plugin restores `exec.signal` to the caller's original in a `finally` so `tools/post-execute` never sees this plugin's (possibly already-aborted) deadline signal. + +`timeout-policy` owns both uses of the `TOOL_TIMEOUT` code: the internal deadline code passed to `deadline()`/`timeoutOf()` (scoped so a nested outer deadline reads as an ordinary cancel) and the structured tool-result error code. Its replacement result is: + +```ts ignore-check +function toolTimeoutResult(callId: CallId, timeoutMs: number): ToolExecutionResult { + return { + callId, + content: [{ type: 'text', text: `Error: tool call timed out after ${timeoutMs}ms` }], + isError: true, + error: { name: 'ToolTimeoutError', code: 'TOOL_TIMEOUT' }, + } +} +``` + +This is a cooperative deadline. It does not kill arbitrary work by racing the tool promise; the tool or the capability it calls must honor `exec.signal` and reach quiescence. "Configured" therefore MEANS "cooperative with `exec.signal`", which the plugin README states as its contract. + +No new session event is needed for reconstructability: `TOOL_TIMEOUT` is the final model-facing `tool/result` for that call, so the existing session log already records the content and structured `{ name, code }` error the next model request sees. + +### Existing tool adaptation + +`web_fetch` and `web_search` are migrated. `dsh-tool-web` keeps ownership of their model-facing schemas, and those schemas expose no timeout knob: `web_fetch` dropped its `timeout_ms` parameter to match the reference-agent shape, and `web_search` stays query-only. The tool bodies do not import `@deepseek-ai/dsh-timeout`; they forward `exec.signal` to `ctx.web`. + +`dsh-web-fetch-local` keeps a provider-level timeout (`timeoutMs`/`maxTimeoutMs`) as a large resource backstop for direct `ctx.web.fetch()` callers and misconfigured deployments; it owns no model-facing timeout. When a `TOOL_TIMEOUT` signal reaches the fetch provider first, provider-scoped classification treats it as upstream `WEB_ABORTED`, and the outer `tools/execute` wrapper replaces the final tool result with `TOOL_TIMEOUT`. A shipped web-tool deployment configures the provider backstop above the `timeout-policy` budget so the tool-call policy normally wins for model calls. + +`bash` stays on the current backend timeout path. `dsh-tool-bash` continues to expose `timeoutMs` and `run_in_background`; `dsh-bash-local` continues to use `@deepseek-ai/dsh-timeout` for `BASH_TIMEOUT`; hook bridges continue to call `runHook()` and pass `timeoutMs` through `ctx.bash`. This keeps foreground/background/hook behavior stable. + +`read`, `write`, `edit`, `todo_write`, `bash_output`, and `bash_kill` do not opt into tool-call timeout: they are local filesystem or short registry/session operations where a deadline would be best-effort only or unnecessary. + +A future model-facing grep/glob tool can be implemented on top of `ctx.bash` without importing `@deepseek-ai/dsh-timeout`: it forwards `exec.signal` to `ctx.bash`, and a deployment configures `timeout-policy` for its budget. If bash-local's backend timeout becomes a problem for such a tool, the bash seam can later add a caller-owned-deadline mode; that is outside this cut. + +## Alternatives considered + +**Name the plugin `tool-timeout`.** The literal RFC name matched the `gen-tool-catalog` completeness guard's `packages/*/tool-*` glob, which requires every match to register a model-facing tool. This plugin registers none — it is a `tools/execute` wrapper — so a `tool-*` name would either fail `verify-tool-catalog` or force a misleading boot entry. The package is `@deepseek-ai/dsh-timeout-policy` in a new `packages/timeout/` group; the cordis.yml `id` can still be `timeout-policy`. + +**Keep per-tool timeout handling only.** This was the shape for `bash` and `web_fetch`, and it matches Claude Code and Codex for shell commands. It loses for web-style tools because every new timeout-capable tool must choose validation, cap semantics, docs, snapshots, and classification. The plugin centralizes policy and classification while leaving each tool's schema focused on business input. + +**Move all timeout policy out of bash-local immediately.** Cleaner long-term — bash-local would become a pure subprocess executor and all callers would own their deadlines. It loses as the first step because hooks call `ctx.bash` directly and the bash model tool has foreground/background semantics that are not the same tool-call lifetime. Keeping `BASH_TIMEOUT` preserves those paths while tool-call timeout proves itself on simpler tools. + +**Use a global default budget for every tool.** Convenient, but it surprises tool authors: any tool that accidentally runs longer than the global budget would start failing once the plugin loads. Per-tool config makes adoption deliberate. + +**Expose a model-facing `timeout_ms` override.** Claude Code's `WebFetch`/`WebSearch` and Codex's web tools keep timeout out of the model-call shape. A model override would make timeout part of prompt semantics and force schema/argument-stripping rules into `timeout-policy`. Web timeout stays deployment policy only. + +**Let `timeout-policy` match tool arguments itself.** A rule engine such as "disable timeout when `bash.run_in_background` is true" would make the policy plugin know tool-specific argument semantics. Avoided by not migrating bash to tool-call timeout. + +**Use `tools/pre-execute` plus `tools/post-execute` instead of a new around seam.** A pre listener could arm a deadline and mutate `exec.signal`; a post listener could classify and replace. That loses because the deadline lifetime would cross two independent waterfalls: a call-id map, cleanup on every pre-deny/tool-throw/post-throw/dispose path, and ordering rules with every other listener. `tools/pre-execute` is also the allow/deny gate, not an execution wrapper. `tools/execute` gives the timeout one lexical scope: arm, delegate, classify, dispose. + +**Use `Promise.race` to enforce timeouts for non-cooperative tools.** Rejected for the same reason as the timeout-library RFC: it returns control to the caller while the underlying process, fetch, or provider operation may still be running. The plugin only sends a signal; termination remains the implementation's responsibility. + +## Consequences + +- `@deepseek-ai/dsh-tools` gains an around-dispatch surface after the interception seams deliberately split pre/post tool hooks. Its contract is narrow — wrap registry dispatch, not replace the pre-gate or post-result policy — and the base `next()` is dispatch-with-normalization so a wrapper never sees a raw tool throw. +- Multiple `tools/execute` listeners compose by ordinary Cordis waterfall order: a listener that calls `next()` wraps downstream listeners plus dispatch; one that returns without `next()` short-circuits them. A deployment combining timeout with a future retry/sandbox/metrics wrapper chooses semantics by registration order ("timeout covers the whole retry" vs "timeout covers each attempt"). +- Config-only opt-in is a deliberate misconfiguration risk: a deployment can configure a timeout for a tool that does not honor `exec.signal`, and that tool will not stop on timeout. The plugin contract states that "configured" means cooperative; the web tools prove the pattern on tools that already forward the signal. +- During the transition `bash` and the migrated web tools use different timeout paths on purpose: `TOOL_TIMEOUT` is the model-facing tool-call budget, while `BASH_TIMEOUT` remains the bash backend timeout used by bash and hooks. +- Deviation from the literal proposal, recorded per the implemented-RFC rule: the plugin package is `@deepseek-ai/dsh-timeout-policy` (not `tool-timeout`), and signal replacement is in-place `exec.signal` mutation before `next()` (not `next({ ...exec, signal })`, which cordis ignores).

As a log event it carries JSDoc prose but **no `@mode` tag** (that vocabulary belongs to cordis bus events; the persistence-catalog generator hard-errors on one) and lands in the regenerated `docs/persistence-catalog.md`; appends happen inside `run_code`'s execution, so the turn-enclosure invariant is satisfied by construction.

Worker-side namespaces are null-prototype with `defineProperty`, so `__proto__`-shaped binding names are ordinary keys. +- **Two independent budgets, because the peer is hostile** — `computeMs` meters the worker's MEASURED busy time (`worker.performance.eventLoopUtilization()` polling): a hot loop cannot hide behind a pending decoy dispatch, and a program awaiting a slow tool accrues nothing. `maxWallMs` backstops what busy time cannot see (awaiting a promise nobody resolves). Both funnel into `worker.terminate()`, which ends hot synchronous loops too; heap overflow surfaces as the worker's OOM exit (`kind: 'worker-exit'`). +- **Logs stream eagerly** — console/stdout/stderr entries cross the port as they happen, so a timed-out or killed program still shows what it printed; pipe bytes that bypass the patched streams are appended after, under the same byte budget. +- **Empty environment** — the worker gets `env: {}` and `execArgv: []`: no ambient credentials (stronger than the scrubbed-env rule for spawned commands) and no inherited loader flags. +- **Dispose to quiescence** — teardown fails in-flight runs as `abort` and AWAITS each worker's exit before resolving. + +## The worker entry, unbuilt and built + +`worker.ts` is deliberately erasable-only TypeScript with type-only cross-package imports: unbuilt (vitest/tsx), the host spawns `src/worker.ts` directly and Node's native type stripping loads it; built, the entry ships as the sibling bundle `lib/worker.js` (its own tsdown entry).

Every inbound message now passes a runtime shape gate that validates and REBUILDS it field by field (junk drops without a throw; call ids must be numbers, so replies are always clone-plain; forged extra fields never ride along). One host-side ledger bounds everything landing in logs — honest port entries, forged ones, and stray pipe bytes — at the single documented maxLogBytes, with the shared in-band truncation marker emitted host-side when the ledger trips first; the completion value is re-capped host-side through the same prepareValue (with exactly the truncation suffix as slack so honest worker-capped values pass unchanged), and done error text is bounded. Also folds the stray-capture budget into that shared ledger (round-1 finding B: it was a second maxLogBytes on top of the documented shared cap). --- docs/config-catalog.md | 2 +- .../code-runtime-worker/README.md | 4 +- .../code-runtime-worker/src/bootstrap.ts | 3 +- .../code-runtime-worker/src/index.ts | 106 ++++++++++++++++-- .../code-runtime-worker/src/protocol.ts | 13 +++ .../code-runtime-worker/tests/runtime.spec.ts | 77 +++++++++++++ 6 files changed, 192 insertions(+), 13 deletions(-) diff --git a/docs/config-catalog.md b/docs/config-catalog.md index 6510aea849..6339911606 100644 --- a/docs/config-catalog.md +++ b/docs/config-catalog.md @@ -171,7 +171,7 @@ export interface Config { } ``` -Source: [`packages/code-runtime/code-runtime-worker/src/index.ts:27`](../packages/code-runtime/code-runtime-worker/src/index.ts) +Source: [`packages/code-runtime/code-runtime-worker/src/index.ts:29`](../packages/code-runtime/code-runtime-worker/src/index.ts) ## `@deepseek-ai/dsh-compact-basic` diff --git a/packages/code-runtime/code-runtime-worker/README.md b/packages/code-runtime/code-runtime-worker/README.md index 13bf992bb5..b8f440397a 100644 --- a/packages/code-runtime/code-runtime-worker/README.md +++ b/packages/code-runtime/code-runtime-worker/README.md @@ -21,9 +21,9 @@ Every field is validated (positive numbers) and defaulted; there are no other tu - **One fresh worker per run, no pooling** — a program's world dies with its worker: no cross-run state to log, state bleed unrepresentable, runs reconstructable from the session log alone. - **Type-strip host-side, in execution context** — the program is wrapped in an async-function shell, stripped with `node:module`'s `stripTypeScriptTypes` (erasable syntax only — `enum`/namespaces are rejected as a program `exception` and no worker spawns), and sliced back out byte-positioned; it then executes as the body of an `AsyncFunction`, so top-level `await`/`return` work. -- **The port assumes a hostile peer** — model code can reach `parentPort` and forge traffic, so the host answers each call id at most once, resolves binding names as OWN properties only (a forged `constructor` cannot walk a prototype chain), drops post-settlement replies, and converts a non-cloneable binding resolution into an error reply.

The harness has nothing that notices: the loop has no step budget, no plugin tracks call repetition, and the model only escapes when it happens to vary its own behavior. The failure mode is real and cheap to detect — [pi-repeat-tool-guard](https://github.com/Kingwl/pi-repeat-tool-guard) ships exactly this as a pi coding-agent extension: count consecutive identical calls and, past a threshold, append a `` telling the model to stop repeating itself and change course. + +The harness already has every seam the pi extension uses, and better ones: [the interception-seams RFC](../../implemented/feature/2026-06-30-interception-seams.md) gives `tools/post-execute` a sanctioned way to attach model-facing context to a finished call, the loop buffers and injects that context with call/result adjacency preserved, and injected context is a logged `context/message` — so a native guard satisfies the model-visible ⟺ logged rule with no new session event. What is missing is only the plugin itself. + +## Proposal + +The guard is a loop-hygiene plugin, not a model-facing tool: it never appears in the tool list, never vetoes or rewrites a call, and adds exactly one behavior — it watches each agent's stream of tool calls, counts runs of consecutive calls to the same tool with identical canonicalized arguments, and at configured run lengths injects an escalating advisory reminder telling the model to stop repeating itself, re-read the last result, and either change approach or conclude. The purpose is to break unproductive loops within a few wasted steps instead of letting them run to the turn's natural end — while leaving the decision (retry differently, gather more evidence, or finish) entirely with the model, so a legitimately repeated call is delayed by nothing and blocked by nothing. + +The shape: one new leaf plugin package, `@deepseek-ai/dsh-repeat-tool-guard` at `packages/guard/repeat-tool-guard/`, opening a `guard/` group for loop-hygiene plugins (single-package groups have precedent: [the todo-write RFC](../../implemented/feature/2026-06-29-todo-write-tool.md) shipped `todo/tool-todo`). The plugin registers three listeners via `ctx.effect()` and holds all state in plugin-local maps keyed by `AgentId` — the tool registry is a context-level singleton whose waterfalls interleave every agent's calls (subagents run on the same context), so per-agent keying is correctness, not polish. + +- **`tools/post-execute` (waterfall)** — the one detection point. The listener receives `(exec, result)` together, so counting and reminder delivery need no cross-event pending map (the pi extension needs one only because its `tool_call`/`tool_result` hooks are separate events). It always delegates via `next()` and, when a threshold is hit, folds a reminder onto the downstream decision's `additionalContext` — the observe-and-enrich posture [the hooks bridges](../../implemented/feature/2026-06-30-hook-bridges.md) already use, honoring the waterfall contract. Counting happens here rather than in `tools/pre-execute` because post-execute also runs for denied calls (`ToolRegistry.execute` routes a deny through the same pipeline), and a model hammering a denied call is exactly the loop worth breaking. +- **`agent/prompt-submit` (waterfall)** — pure reset hook: delegate via `next()`, clear the submitting agent's chain. A user interjection changes the context; repetition across it is not a loop. +- **`agent/status` (emit)** — on `disposed`, drop the agent's state, bounding the maps over harness lifetime. + +### Detection semantics + +The chain key is `(tool name, canonical arguments)`; a call identical to the previous tracked call increments the agent's consecutive counter, a different tracked call resets it to 1. Canonicalization is a deep key-sort plus `JSON.stringify`: `ToolExecution.arguments` is by construction the loop's `JSON.parse` output (or the raw string fallback for malformed argument JSON, which is itself a comparable value), so the pi original's bigint/circular/`undefined` handling has no inputs here and is deliberately dropped. + +Two deliberate rules, both documented in the package README because they are behavior a reader would otherwise guess at: + +- **Untracked calls are transparent to the chain.** A call excluded by `include`/`exclude` neither increments nor resets the counter, so `grep X → todo_write → grep X` still counts as two consecutive `grep X` when `todo_write` is excluded. This is what makes exclusion useful — bookkeeping tools interleaved into a loop must not launder it — and it is the pi extension's (undocumented) semantics, kept on purpose and written down. +- **Calls without an agent are ignored.** A direct `ctx.tools.execute()` caller (tests, future non-loop consumers) has no model to remind and no `AgentId` to key on. + +### Reminder delivery + +Reminders ride `additionalContext` (source `{kind: 'plugin', plugin: 'repeat-tool-guard'}` — the label is load-bearing per `HookContext`), never a `content` replacement: the `tool/result` event stays the tool's own output for audit, and the loop already appends buffered context as `context/message`(s) after the step's results, which the session renders as the tagged synthetic-user envelope and derived history replays. Thresholds escalate: the first configured threshold gets a short "you are repeating yourself, analyze the previous result" nudge; each later threshold gets the detailed form naming the tool, the repeat count, and the canonical arguments, and stating that the calls made no progress. The pi original hardcodes the gentle text to the literal count 3; the guard keys it to `thresholds[0]`, fixing that bug in the port. When the downstream decision already carries `additionalContext` (a hook bridge on the same call), the guard folds content following the shared-merge precedent in `dsh-hook-protocol`. + +### Config + +```yaml +- id: repeat-tool-guard + name: '@deepseek-ai/dsh-repeat-tool-guard' + config: + thresholds: [3, 5, 8] # default; consecutive counts that trigger a reminder + include: [] # tool-name patterns to track; empty ⇒ all tools + exclude: [todo_write] # tool-name patterns transparent to the chain +``` + +`thresholds` is validated at load and throws on an empty list, a non-integer, a value below 2, or a duplicate — misconfiguration fails loud, replacing the pi original's silent fall-back to defaults. `include`/`exclude` entries support `*` wildcards. Patterns are predicates over whatever tools exist at call time, not references to a registry entry, so an entry matching no currently registered tool is NOT an error — unlike `toolOrder`'s referent check, `exclude: [mcp_*]` must stay valid in a deployment that loads no MCP tools. + +### Testing + +Coverage named at plan time, per tier: **unit** — counting/reset semantics (identical, different-tracked, untracked-transparent, prompt-submit reset, disposal cleanup, per-agent isolation), canonicalization, threshold escalation including the `thresholds[0]` gentle-text rule, config fail-loud cases, and the fold-onto-downstream-decision path, to per-file 100% like every `packages/*/*/src` file. **Snapshot** — one scripted-replay scenario where the model repeats a call to threshold and the reminder `context/message` appears in the transcript, pinning the model-visible text and its envelope (this is a transcript-surface change; the ACP snapshot suite is the tier that owns it). **e2e** — none: the plugin is provider-independent and deterministic, and forcing a live model to repeat a call three times is not a stable test; the seam contracts it relies on are already e2e-covered by their owners. + +## Alternatives considered + +- **Append the reminder into the tool result** (`accept` with replaced `content` — the pi extension's mechanism, which patches result content because that is the only channel its API offers) — rejected: it makes the logged `tool/result` lie about what the tool returned, and `additionalContext` exists precisely as the separate sanctioned channel for post-execute commentary, with loop-level buffering that preserves call/result adjacency. +- **Count in `tools/pre-execute` with a pending-reminder map** (the pi two-phase shape) — rejected: post-execute alone sees `(exec, result)` together and also fires for denied calls, so one listener with no cross-event state covers strictly more attempts with less machinery. +- **Escalate to `block` at the highest threshold** — rejected for the initial scope: a blocked call punishes legitimate identical repeats (polling a long-running terminal, re-checking a file the agent expects to change), and an advisory reminder keeps the model in control.

Mitigation: conservative defaults and the reminder text explicitly allowing "finish the task if enough evidence has been gathered". +- **Reminder tokens are model-visible cost.** Each trigger appends a paragraph to the next request; thresholds bound the frequency, but a pathological agent can hit 3/5/8 repeatedly across different keys. +- **State is in-memory only.** A session resumed from persistence starts with a fresh chain, so a loop spanning a resume gets its reminders later than a live one — accepted: the guard is a heuristic nudge, not a logged invariant, and persisting counter state would buy little for real complexity. +- **Multiple context producers on one call.** When a hook bridge and the guard both attach `additionalContext`, ordering follows listener registration order; the fold keeps both, but the combined envelope's readability depends on merge behavior that this RFC inherits rather than owns. + +## Open questions + +- Should compaction reset chains? A compacted history changes what the model sees, but the repetition risk usually survives compaction; the initial answer is no. +- Should subagents inherit the parent's thresholds via config only, or ever share chain state?

The loop buffers the context and appends it as a `context/message` after the step's tool results, which the session renders as the tagged synthetic-user envelope — so the reminder is model-visible, source-attributed, and reconstructable from the session log with no new session event. The guard always delegates via `next()` and folds its reminder onto the downstream decision (both variants — a blocked call still gets the nudge); when a downstream listener attached its own `additionalContext`, the fold concatenates content and carries the guard's `source` (a `HookContext` holds one `MessageSource`; `source.kind` is what framing depends on). + +## Testing + +Unit suites drive a real agent loop against a mock adapter (no network) and cover the chain semantics above to per-file 100%.

re-issues the same tool call with byte-identical arguments — re-running a failing grep, re-reading an unchanged file, polling a command that already gave its answer — and each round trip burns tokens, wall-clock, and (for paid APIs) money without adding information. The harness has nothing that notices: the loop has no step budget, no plugin tracks call repetition, and the model only escapes when it happens to vary its own behavior. The failure mode is real and cheap to detect — [pi-repeat-tool-guard](https://github.com/Kingwl/pi-repeat-tool-guard) ships exactly this as a pi coding-agent extension: count consecutive identical calls and, past a threshold, append a `` telling the model to stop repeating itself and change course. -The harness already has every seam the pi extension uses, and better ones: [the interception-seams RFC](../../implemented/feature/2026-06-30-interception-seams.md) gives `tools/post-execute` a sanctioned way to attach model-facing context to a finished call, the loop buffers and injects that context with call/result adjacency preserved, and injected context is a logged `context/message` — so a native guard satisfies the model-visible ⟺ logged rule with no new session event.

What was missing was only the plugin itself. -## Proposal +## Decision The guard is a loop-hygiene plugin, not a model-facing tool: it never appears in the tool list, never vetoes or rewrites a call, and adds exactly one behavior — it watches each agent's stream of tool calls, counts runs of consecutive calls to the same tool with identical canonicalized arguments, and at configured run lengths injects an escalating advisory reminder telling the model to stop repeating itself, re-read the last result, and either change approach or conclude. The purpose is to break unproductive loops within a few wasted steps instead of letting them run to the turn's natural end — while leaving the decision (retry differently, gather more evidence, or finish) entirely with the model, so a legitimately repeated call is delayed by nothing and blocked by nothing. -The shape: one new leaf plugin package, `@deepseek-ai/dsh-repeat-tool-guard` at `packages/guard/repeat-tool-guard/`, opening a `guard/` group for loop-hygiene plugins (single-package groups have precedent: [the todo-write RFC](../../implemented/feature/2026-06-29-todo-write-tool.md) shipped `todo/tool-todo`).

Revisit with evidence; the decision shape (`PostToolDecision`) already supports it. -- **A per-deployment external hook via the CC/Codex bridges** (a `PostToolUse` script) — rejected as the answer: it works today for one deployment, but a shipped, unit-tested, `cordis.yml`-configurable plugin is the harness-native form, without per-call subprocess cost. +- **A per-deployment external hook via the CC/Codex bridges** (a `PostToolUse` script) — rejected as the answer: it works for one deployment, but a shipped, unit-tested, `cordis.yml`-configurable plugin is the harness-native form, without per-call subprocess cost. - **A loop-level step or repetition budget in `agent-loop`** — rejected: "plugins, not loop changes"; a hard step budget is a blunter, orthogonal control that would need its own proposal. - **Fuzzy/near-identical detection** (normalized paths, similar-but-not-equal arguments) — rejected: exact match after canonicalization is cheap, deterministic, and explainable to the model; similarity thresholds invite false positives and need evidence before they earn complexity. - **Placing the package in `core/`** — rejected: core is the product spine; a behavioral guard is an optional leaf plugin, and the `todo/` precedent is a small dedicated group per plugin family. -## Acceptance criteria +## Consequences -- `packages/guard/repeat-tool-guard/` exists, registers all listeners through `ctx.effect()`, and is loadable from a `cordis.yml` with the config above; the config catalog regenerates with its entry. -- Invalid `thresholds` (empty, non-integer, `< 2`, duplicate) throw at plugin load. -- Unit suite covers the semantics list above at per-file 100%; a snapshot scenario replays a threshold-crossing repetition and pins the reminder `context/message` in the transcript on macOS and Linux. -- The reminder is reconstructable from the session log alone (it is an ordinary `context/message` with a plugin source — no new session event). -- The package README opens with the plugin's purpose — an advisory loop-breaker that is not a model-facing tool, never blocks or rewrites a call, and only injects reminders — then documents the transparency rule, the per-agent keying, and the in-memory-only state; `doc-sync` is green. +- The reminder is advisory by design: idempotent polling patterns that repeat identical calls on purpose still receive nudges past the thresholds, and the pressure valves are config (`thresholds`, `exclude`) plus reminder text that explicitly allows finishing when enough evidence has been gathered. Each trigger costs reminder tokens on the next request; thresholds bound the frequency. +- Chain state is in-memory only: a session resumed from persistence starts with a fresh chain, so a loop spanning a resume draws its reminders later than a live one — accepted, the guard is a heuristic nudge, not a logged invariant, and persisting counter state would buy little for real complexity. +- When multiple post-execute producers attach context on one call, the fold concatenates under the guard's `source`; ordering between plugins follows listener registration order. The seam cannot represent mixed provenance — a limit inherited from `HookContext`, not owned by this plugin. +- Implementing the snapshot tier surfaced a hidden assumption in the suite kit: the fixture guard equated "authored model scenario" with "override-driven". The `Scenario` table now carries an explicit `overridden` flag, and the sidecar's presence is checked BOTH ways against it (an unregistered stray sidecar would silently replace the derived script) — the suite kit is stricter than it was before this plugin existed. -## Risks +## Deferred -- **False positives on legitimately repeated calls.** Idempotent polling patterns repeat identical calls on purpose; the reminder is advisory and thresholds/`exclude` are the pressure valves, but a badly tuned deployment adds noise to the transcript. Mitigation: conservative defaults and the reminder text explicitly allowing "finish the task if enough evidence has been gathered". -- **Reminder tokens are model-visible cost.** Each trigger appends a paragraph to the next request; thresholds bound the frequency, but a pathological agent can hit 3/5/8 repeatedly across different keys. -- **State is in-memory only.** A session resumed from persistence starts with a fresh chain, so a loop spanning a resume gets its reminders later than a live one — accepted: the guard is a heuristic nudge, not a logged invariant, and persisting counter state would buy little for real complexity. -- **Multiple context producers on one call.** When a hook bridge and the guard both attach `additionalContext`, ordering follows listener registration order; the fold keeps both, but the combined envelope's readability depends on merge behavior that this RFC inherits rather than owns. - -## Open questions - -- Should compaction reset chains? A compacted history changes what the model sees, but the repetition risk usually survives compaction; the initial answer is no. -- Should subagents inherit the parent's thresholds via config only, or ever share chain state? Per-agent isolation is the proposed default; sharing looks like a smell until a concrete case appears. +- Compaction does not reset chains: a compacted history changes what the model sees, but the repetition risk usually survives compaction. +- Escalating to `block` at a high threshold is not implemented; `PostToolDecision` already supports it if evidence arrives. +- Subagent chains stay isolated per agent; no sharing mechanism exists until a concrete case appears.

Because the tool set is dynamic (plugins register in `cordis.yml` order, HMR re-registers), this is not a load-time error — a real tool may register later. Instead, on every `tools/change` (and once at load) the plugin `logger.warn`s each configured name still absent from `ctx.tools`, warning each name at most once so a late registration silences it. This mirrors `dsh-tool-subagent`'s lifecycle-driven handling of a configured-but-unregistered provider name. +The per-tool budget is declared by the tool plugin (e.g. `dsh-tool-web`'s `fetchTimeoutMs`/`searchTimeoutMs` config, attached as `ToolDefinition.timeoutMs`); this plugin only enforces it, so a mistyped tool name is not possible. ### Behavior -For a **configured** tool the listener: +For a tool that **declares a `timeoutMs`** the listener: -1.

Reads the budget from the tool's own declaration in the registry (`ctx.tools.get(exec.name)?.timeoutMs`) and arms `deadline(exec.signal, timeoutMs, 'TOOL_TIMEOUT')` — one signal fusing the caller's abort with this plugin's timer (`@deepseek-ai/dsh-timeout`). 2. Swaps that derived signal onto `exec` for the downstream dispatch, then restores the caller's own signal afterward (cordis `next()` ignores passed arguments, so the wrapper mutates the shared `exec` in place; restoring keeps `tools/post-execute` seeing the caller's signal). 3. After dispatch, if `timeoutOf(d.signal, 'TOOL_TIMEOUT')` matches — this plugin's own timer fired — replaces the result with a structured `TOOL_TIMEOUT` tool result: `{ isError: true, error: { name: 'ToolTimeoutError', code: 'TOOL_TIMEOUT' }, content: 'Error: tool call timed out after ms' }`. -An **unconfigured** tool delegates untouched (no deadline). +A tool that **declares no budget** delegates untouched (no deadline). The base `next()` of `tools/execute` is the registry's dispatch-with-normalization thunk, so when the timeout signal reaches a provider that throws its own upstream-abort error, dispatch first turns it into a normal error result, and this wrapper then replaces that with `TOOL_TIMEOUT`. That ordering is why the replacement is keyed off the signal (`timeoutOf`), not off the dispatched result's shape. ### Cooperative, not a hard kill -The derived signal only **notifies**; termination stays with the tool and the capability it forwards `exec.signal` to (the `dsh-timeout` library owns no kill). **"Configured" therefore means "cooperative with `exec.signal`"**: a tool that ignores the signal will not stop on timeout.

All three are described in `## Decision` above.
