Native function calling therefore had a usable human projection, but a programmatic caller had no stable domain value: Code Mode flattened the blocks back into a string, dynamic tools repeated the content shape, and policy could replace presentation without any way to distinguish that change from replacing the operation's result. Several capability seams already returned richer provider values only to discard them at their model-facing tool boundary. + +The durable session contract made that presentation authoritative for replay, but persisting every rich intermediate value would enlarge logs, expose implementation data to compaction and migration, and incorrectly turn an execution-local API into session format.

Renderer, projector, schema, or lossless-JSON failures are contained as ordinary `ToolOutputError` results. An around `tools/execute` wrapper receives and returns the canonical success/failure union; a wrapper-authored success is normalized again through the resolved tool's output declaration instead of trusting independently authored content. Canonical-result provenance is scoped to the immutable dispatch token, so returning a cached result from another call or tool triggers normalization under the active declaration rather than bypassing it. + +```ts ignore-check +type ToolExecutionResult = + | { isError: false; value: JsonValue; content: ContentBlock[]; meta?: JsonValue; additionalContexts?: HookContext[] } + | { isError: true; error: { message: string; info?: { name: string; code: string } }; content: ContentBlock[]; meta?: JsonValue; additionalContexts?: HookContext[] } +``` + +`tools/post-execute` has two mutually exclusive successful projections. Replacing `content` changes only Native/model presentation and preserves the canonical value and metadata. Replacing `value` revalidates the replacement and recomputes both presentation projections. A block removes the value and becomes a failure. Content replacement is therefore not a confidentiality mechanism: policy that must prevent programmatic access blocks the call or replaces the value. + +Canonical values are execution-local. The agent loop persists `tool/result` with only `content`, `error`, and optional `meta`; Code Mode's `tool/code-dispatch` persists only its bounded summary. Neither event stores the intermediate value, so replay reproduces presentation but cannot reconstruct the programmatic result. When a tool declares `presentationMeta`, it is computed only for a direct surface call; a nested Code dispatch gets no metadata or result card. The outer `run_code` card instead reads final post-policy content and declares no presentation metadata.

Their omission from the log means replay cannot recover them, and a content-only post policy does not hide them.

The [web client architecture note](2026-07-19-gui-web-client-architecture.md) carries the shipped-state narrative this decision produced; the [slot system standard](2026-07-22-slot-type-chain-implementation.md) owns the registration model everything now runs on. + +## Problem + +After the view ring dissolved into the slot system, the client kept exactly one parallel registration model: the tool ring — a named registry (`ctx.toolviews`) with its own register grammar, its own resolve semantics (scoped-beats-global predicate dispatch), its own subscribe/version pair, its own inject cache, and its own render outlet with a private error boundary. Every one of those was a second implementation of something the slot machinery already owned, and every future capability (a store seat for row drafts, i18n injection, cross-bundle identity) would have had to be built twice or drift. The ring's one honest justification was that tool names are a runtime-open set while `SlotMap` is a closed declaration table — a registry keyed by arbitrary strings seemed structurally necessary. + +## Decision + +The tool ring is gone as independent infrastructure: a tool row is a **keyed child slot each view declares for itself**, and the client has exactly one registration model. The justification above was hollow — a keyed slot's *key space* is already runtime-open (SlotMap declares slots, never keys; the ask-user composer's `key: 'question'` was the precedent), so the open tool-name set fits `entryKey` dispatch natively. + +Shipped shape (current-state narrative also in the [architecture note](2026-07-19-gui-web-client-architecture.md)): the chat entry's `children` table declares `'conversation.chat.toolview'` (keyed/session); the render site dispatches per row via `entryKey: toolName` with `GenericToolCard` as the call-site `fallback` (the default card is domain property; the fallback option is ordinary renderSlot grammar). The owner payload is the uniform `ToolRowOwnerProps` (`callId`/`toolName`/`block`/`openDetails` — details being a session-level facility, not chat-private), and `ToolRowProps` pre-composes it with the session standard kit for registrant components. A registrant is a plain plugin: `ctx.slots.register({ name: 'conversation.chat.toolview', key: '', inject? }, Row)` with `inject: ['slots', 'conversation']` as the load-order seam — apply mounts `ConversationService` *after* the chat registration, so the service being present guarantees the slot is declared, by construction. Session-dimension differentiation happens inside the component (`useSessions` reading `parentId` — the decision sits where all the information already is); the bash sample is the third-party-posture exemplar. Trajectory/waterfall toolview slots share this exact shape (names fixed by the slot-naming discipline `..`, one shared owner type) and land with their own row render sites — RendersCheck rejects a declaration nobody renders, so the type system, not convention, blocks early empty declarations. + +Registry-era responsibilities all have successor homes: inject caching and row error isolation ride the framework renderer (entry×scope cache, per-entry `SlotErrorBoundary`); subscribe/getVersion ride the slot core's per-key version machinery; the future "store seat" is the ordinary store seat keyed slots already have (interaction-draft durability is its first named consumer); miss fallback is the call-site `fallback` option. + +## Accepted semantic changes + +Four behavioral deltas were accepted deliberately, not overlooked. Cross-view appearance is per-view registration — a row must adapt to each view's layout anyway, so one registration per view is the correct coupling, and reuse is the same component in two register calls. Same-key double registration is a loud throw where the registry let later-wins silently override — a discipline correction, not a loss. Session-dimension dispatch moved from registry predicates into the component. Registry-level shape override by third parties (a scoped registration shadowing a global one) has no equivalent; a real future need routes through key-naming conventions or a small in-component resolver, never a revived parallel registry. + +## Alternatives considered + +**Keep the standalone registry (the original shape).** Rejected: each of its multi-dimensional dispatch axes has a more correct home — the view dimension belongs to each view's own declared child slot (declaring is claiming, so specialization ownership lands right), and the session dimension belongs inside the component, which already holds the standard kit. What remained after both moves was a second copy of slot machinery with no distinguishing capability. + +**Promote `renderToolView` into the standard kit and move the registry into the runtime package.** Rejected: "tool row" is a conversation-domain concept; hoisting it into runtime would leak a domain vocabulary into the framework layer and still leave two registration models. + +**Derive slot declarations from subscription refCounts** (declare the slot implicitly when the first registrant subscribes). Rejected for implicit coupling and debounce complexity; noted as a possible revisit only if a genuinely multi-viewer surface appears. + +**A thin `registerToolView` facade over slots.register.** Deferred, not rejected: after dissolution the facade would carry only compile-time sugar (slot-name literal narrowing, tool→key vocabulary, props pre-composition) with zero runtime. Per "enforce at the operation boundary" (a facade is not an enforcement point) and "don't split preemptively" (today's registrant population is one bash sample), it stays unbuilt; the type sugar ships as the exported `ToolRowProps` alias. Regret clause: if registrants grow to three-to-five or a bulk-registration pattern appears, the facade is ten lines added without disturbing direct registration. + +## Consequences + +The client has one registration model; auditing who renders tool rows = reading register calls, the same audit as every other slot. Registrants get the framework's error isolation, inject caching, and store seat for free — no capability ships twice. The costs are the accepted semantic changes above (chiefly: per-view registration for cross-view rows, and no third-party registry-level override), plus one subtlety the load-order seam carries: registrant plugins must declare `inject: ['conversation']` to sequence after the slot declaration, a convention the seam makes correct by construction but does not statically force on third parties. diff --git a/.agents/notes/implemented/architecture/2026-07-23-toolview-dissolution.zh.md b/.agents/notes/implemented/architecture/2026-07-23-toolview-dissolution.zh.md new file mode 100644 index 0000000000..47c1f392f5 --- /dev/null +++ b/.agents/notes/implemented/architecture/2026-07-23-toolview-dissolution.zh.md @@ -0,0 +1,37 @@ +# Agent Note: toolview 溶解——工具行即 per-view keyed slot + +Status: implemented + +[English](2026-07-23-toolview-dissolution.md) | 中文 + +> 范围：独立工具环（ToolViewRegistry/ctx.toolviews/outlet）为何退役、被什么取代。本决策产出的落地态叙述归 [Web 客户端架构注](2026-07-19-gui-web-client-architecture.md)；一切现在所运行其上的注册模型归 [slot 体系标准](2026-07-22-slot-type-chain-implementation.md) 所有。 + +## Problem + +视图环溶解进 slot 体系之后，client 侧恰好还剩一套平行注册模型：工具环——一个具名注册表（`ctx.toolviews`），带自己的 register 文法、自己的 resolve 语义（scoped 压 global 的谓词分发）、自己的 subscribe/version 对、自己的 inject 缓存、自己带私有错误边界的渲染出口。其中每一件都是 slot 机器已经拥有之物的第二份实现，而每一项未来能力（行草稿的 store 席位、i18n 注入、跨 bundle 身份）都将不得不建两遍或漂移。这条环唯一像样的存在理由是：tool 名是运行时开放集，而 `SlotMap` 是封闭声明表——以任意字符串为键的注册表看似结构上必需。 + +## Decision + +工具环作为独立基础设施已消失：工具行是**各视图为自己声明的 keyed 子槽**，client 全域只剩一种注册模型。上述理由是空的——keyed slot 的 *key 空间*本就运行时开放（SlotMap 声明槽、从不声明 key；ask-user composer 的 `key: 'question'` 即先例），开放的 tool 名集合天然适配 `entryKey` 分发。 + +落地形态（现状叙述同见[架构注](2026-07-19-gui-web-client-architecture.md)）：chat 条目的 `children` 表声明 `'conversation.chat.toolview'`（keyed/session）；渲染点逐行以 `entryKey: toolName` 分发、以 `GenericToolCard` 作调用点 `fallback`（默认卡片是域产权；fallback 选项就是普通 renderSlot 文法）。owner 载荷是统一的 `ToolRowOwnerProps`（`callId`/`toolName`/`block`/`openDetails`——details 是会话级设施，非 chat 私货），`ToolRowProps` 把它与 session 标配 kit 预组合供注册方组件取用。注册方就是普通插件：`ctx.slots.register({ name: 'conversation.chat.toolview', key: '', inject? }, Row)`，以 `inject: ['slots', 'conversation']` 作加载序缝——apply 把 `ConversationService` 挂在 chat 注册*之后*，故服务在场即保证槽已声明，构造使然。会话维差异化在组件内完成（`useSessions` 读 `parentId`——决策放在已有全部信息的地方）；bash 样例即第三方姿态的样板。trajectory/waterfall 的 toolview 槽共用这套形状（槽名按槽名纪律 `<域>.<条目>.<孔位>` 定死，共用一张 owner 类型），随各自的行渲染点落地——RendersCheck 拒绝无人渲染的声明，挡住提前空声明的是类型系统而非约定。 + +registry 时代的职责各有后继居所：inject 缓存与行错误隔离乘框架渲染器（entry×scope 缓存、per-entry `SlotErrorBoundary`）；subscribe/getVersion 乘 slot core 的 per-key 版本机；将来的「store 席位」就是 keyed slot 本就拥有的普通 store 席位（交互草稿耐久性是其首个具名消费者）；miss 兜底即调用点 `fallback` 选项。 + +## 接受的语义变化 + +四项行为增量是刻意接受而非疏漏。跨视图出场=逐视图注册——行本须适配各视图版式，一视图一注册是正确耦合，复用即同一组件写两次 register。同 key 重复注册从注册表的 later-wins 静默覆盖变为 loud throw——纪律修正而非损失。会话维分发从注册表谓词移入组件。第三方在 registry 级覆盖形态（scoped 注册压过 global）不复存在；真出现的未来需求走 key 命名空间约定或组件内小 resolver，永不复活平行注册表。 + +## Alternatives considered + +**保留独立注册表（原形态）。** 拒绝：其多维分发的每一维都有更正确的家——视图维归各视图自己声明的子槽（declaring is claiming，特化面权属自然落对），会话维归已持有标配 kit 的组件内部。两步移完后剩下的只是一份没有任何独有能力的 slot 机器副本。 + +**把 `renderToolView` 提进标配 kit、注册表迁入 runtime 包。** 拒绝：「工具行」是 conversation 域概念；上提进 runtime 会把域词汇泄漏进框架层，且依然留着两套注册模型。 + +**以订阅 refCount 推导槽声明**（首个注册方订阅时隐式声明槽）。拒绝：隐式耦合加去抖复杂度；记为将来真出现多观看面时的备选。 + +**slots.register 之上的薄 `registerToolView` 门面。** 缓建而非拒绝：溶解后该门面只剩编译期三糖（槽名字面量收窄、tool→key 词汇翻译、props 预组合），运行时为零。按「enforce at the operation boundary」（门面不是强制点）与「don't split preemptively」（今天注册方人口只有一个 bash 样例）保持不建；类型糖以导出的 `ToolRowProps` 别名兑现。后悔药条款：注册方长到三五家或出现批量注册模式时，门面十行可补，不扰直注。 + +## Consequences + +client 只有一种注册模型；审计谁渲染工具行 = 读 register 调用，与其他所有 slot 同一套审计。注册方免费获得框架的错误隔离、inject 缓存与 store 席位——没有能力要建两遍。代价即上文接受的语义变化（主要是：跨视图行要逐视图注册、第三方无 registry 级覆盖），外加加载序缝携带的一处微妙：注册方插件须声明 `inject: ['conversation']` 才排在槽声明之后，这条约定由序缝构造保证正确、但不对第三方静态强制。 diff --git a/.agents/notes/implemented/bug-fix/2026-07-20-code-mode-result-card-completeness.i18n.yaml b/.agents/notes/implemented/bug-fix/2026-07-20-code-mode-result-card-completeness.i18n.yaml new file mode 100644 index 0000000000..8453907b5c --- /dev/null +++ b/.agents/notes/implemented/bug-fix/2026-07-20-code-mode-result-card-completeness.i18n.yaml @@ -0,0 +1,6 @@ +# Bilingual-pair consistency record (docs/i18n/README.md): the git blob hash of each +# side as of the last confirmed-consistent state.

An outer post-execute block discards tool-deferred entries and exposes only contexts explicitly attached by the blocking decision. **Concurrency is serialized.** Each run owns a dispatch queue, so even `Promise.all` executes tool calls in submission order.

Unsupported raw constructs degrade to `unknown` during prompt generation rather than breaking assembly. Tool names retain their exact keys, including names that require quoted access. + +### Binding values and failures + +Before dispatch the bridge snapshots binding arguments as lossless JSON and snapshots the detached value again for an independent durable summary event. Host-side detachment, immutable execution, and output-schema projection all use iterative traversals rather than nested structured clone or recursive freezing. `undefined`, non-finite numbers, `-0`, sparse arrays, cycles, functions, and exotic objects reject that call before the tool runs. Successful dispatch returns `ToolExecutionResult.value`; Native `content`, metadata, and internal error information do not cross to the program. + +Code Mode declares its rejection capability on the runtime request as `{ name: "ToolCallError", memberNameProperty: "toolName" }`. The runtime seam treats those names as data: the worker materializes and injects the actual constructor used for `tools` binding failures, so `error instanceof ToolCallError` works without making a generic runtime know about tools. The worker constructs failures and defines their public fields through module-captured error and property-definition intrinsics plus null-prototype descriptors, so model mutations cannot replace the promised rejection with a worker failure. The error has the standard `Error` message plus the exact `toolName`; it deliberately omits `ToolFailure.info`, error codes, and Native content. This is an exception contract for control flow, not a failure union for programmatic classification. + +Binding arguments and resolutions are revalidated as lossless JSON on both sides of the hostile worker protocol and have no byte cap. Before crossing through structured clone, each detached value is encoded as a flat pre-order token stream whose transport nesting is bounded; the receiver rebuilds it iteratively. Valid application nesting therefore has neither a JavaScript call-stack depth cap nor a platform-specific nested structured-clone limit. At module initialization the worker captures its own realm's `Array.prototype` and `Object.prototype` identities, the native function-source intrinsic used only to recognize foreign-realm plain-container prototypes, and every structural and metering intrinsic used by the JSON boundary. Property writes use null-prototype descriptors, while private array and set operations invoke captured methods without consulting mutable global or prototype slots. Model code can therefore replace helpers such as `Object.keys`, `Array.isArray`, collection methods, string methods, or `Buffer.byteLength`, rewrite intrinsic-prototype constructor slots, or add descriptor-shaped fields to `Object.prototype` without changing validation, wire transport, or byte accounting. The foreign-realm native function-source check still rejects user-authored constructors that imitate `Object` or `Array`. The dependency-light runtime seam names its structural equivalent `CodeJsonValue` so it need not depend on the session-owned canonical type; the generated SDK and tool API use `JsonValue`. Intermediate values are not prompt-truncated, context-spilled, or persisted. This preserves full acquired search, workflow, task, filesystem, and MCP values for programmatic filtering while leaving provider and executor acquisition limits truthful. + +### Outer result and output ledger + +The runtime accepts an exact lossless JSON completion of any root. Returning `undefined` omits the completion; returning `null` is an explicit result. `run_code` exposes the canonical outer value `{ logs: string[], result?: JsonValue }`. Its Native renderer emits logs first, renders a string result raw, and renders every other JSON root with an iterative pretty printer. Total indentation is capped at ten characters and deeper subtrees remain compact, preserving the established shallow text while keeping traversal stack-safe and formatted size linear in the canonical JSON size. + +`WorkerCodeRuntime` replaces the former independent log and value caps with configurable `maxOutputBytes`, defaulting to `67_108_864` bytes. The worker charges captured logs by their exact JSON-string serialization and preflights the detached completion or program exception against the remaining combined budget before posting a terminal message. A giant thrown string or stack therefore crosses the worker port only as the fixed `output-limit` diagnostic. The host repeats the hostile-peer ledger for forged traffic and native pipe writes the worker cannot observe. Fixed `CodeRunResult` field names, braces, the bounded error-kind tag, and later presentation whitespace are deliberately outside this variable-payload ledger. Neither stage materializes an over-limit serialized completion. A result at or below the cap is exact. A completion that cannot survive lossless JSON snapshotting fails as `invalid-output`; a value, diagnostic, or combined outcome over the cap fails as `output-limit` rather than becoming inspected or truncated text. + +Logs stream eagerly so a terminated run can retain output already admitted. Native stdout and stderr writes that bypass the worker's patched stream slots use independent pipes, so terminal settlement continues bounded capture until worker termination completes before materializing the result. When the cap is crossed, the runtime returns an explicit bounded failure with the fitting captured prefix. That outer result then traverses the ordinary `run_code` rendering and spill policy, which may save the captured text and expose its configured head/tail preview. The spill layer cannot recover bytes the runtime rejected beyond the hard cap. + +Compute time, wall time, worker heap, cancellation, and fresh-worker isolation remain independent limits. The outer ledger never charges intermediate bindings, so snapshotting, flat-wire encoding and decoding, structured-clone cost, and available process or worker memory are their practical bounds. + +### Typed handles and lifetime + +Background producers return a typed canonical handle such as `{ kind: 'background', taskId }` while retaining their established Native sentence. A pre-aborted background call remains a failure because successful output promises an id and no task was created. After `ctx.tasks.start()` publishes the id, task-owned cancellation governs the work: settlement or later cancellation of the enclosing `run_code` call does not kill it. A later program can pass the returned id to `task_output`, and `task_kill`, owner disposal, or service teardown owns cancellation. Foreground execution remains coupled to the call signal. The task lifetime contract is owned by the [background task runtime note](../architecture/2026-06-20-generic-long-running-tool-runtime.md). + +Dynamic Cordis mounting follows the same rule: `cordis_mount` returns `{ id, pluginName, state, provides, waitingFor }`, so a program can read `mounted.id`, inspect active or pending state, and pass that id to `cordis_unmount` without parsing the stable Native sentence. + +### Persistence, metadata, and spill + +Nested dispatch keeps the existing bounded `tool/code-dispatch.resultSummary` for diagnostics but does not persist canonical values. `tool/result` continues to persist only rendered content, error, and optional metadata. This is deliberately not a session-format change, so `SESSION_FORMAT_VERSION` remains unchanged and replay cannot recreate intermediate program values. + +The opaque `exec.parent` token marks nested calls. Presentation metadata and generic or tool-owned spill projections skip those calls because they have no direct result card and their canonical values never enter context. The outer `run_code` call alone produces one card and may spill its final post-policy presentation; `run_code` intentionally declares neither a result presenter nor presentation metadata, so ACP and TUI complete the card through their generic raw-content fallback using durable `tool/result.content`. + +## Testing + +Compile-time and snapshot tests pin exact `ToolArgsMap`, `ToolOutputMap`, `ToolName`, schema-to-TypeScript coverage, and exotic names. Registry and real-worker tests cover scalar, array, object, and null values; raw string rendering; absent `undefined`; consumer-declared real rejection classes, including `ToolCallError`; invalid arguments and completions, including intrinsic-looking forged prototypes; model-mutated JSON-boundary globals, prototype methods, constructor slots, and inherited descriptor fields; typed binding failures after those mutations; large uncapped intermediate bindings; nested spill suppression; exact and over-limit 64 MiB accounting; combined logs/value/diagnostic accounting; giant thrown stacks; bounded failure spill; hostile forged traffic; and built-package execution. + +Keyless real-worker integration tests pin the two handle workflows that prose results could not safely support. A background bash call returns its task id, the outer run settles, and a later run polls that id to completion; separate cases prove pre-abort creates no task, post-publication call abort preserves the task, foreground execution stays signal-coupled, and `task_kill` owns cancellation. A Cordis program reads an active or pending mount's id and `waitingFor` fields directly, unmounts by that id, and confirms removal without parsing rendered text. + +## Alternatives considered + +**Return Native text plus optional JSON.** Rejected because the program would have two competing success contracts and would still need tool-specific parsing rules when the optional value is absent. Canonical value is the API; Native content is its presentation. + +**Expose a success/failure union from every binding.** Rejected because failure has no stable programmatic taxonomy. Rejections preserve ordinary `try`/`catch` control flow and expose only the tool name and human-readable message. + +**Cap each intermediate binding.** Rejected because intermediate values are not placed in model context and arbitrary truncation would corrupt programmatic composition. The producer's acquisition contract and process memory remain explicit boundaries. + +**Silently inspect or truncate an oversized completion.** Rejected because changing a JSON value into a string is lossy and type-incorrect. The explicit `output-limit` failure lets the model choose a smaller result, while the retained logs and diagnostic can still use normal outer spill. + +## Consequences + +Code programs can compose tools through stable values instead of reverse-engineering Native prose. Native and Both Mode retain their existing text and editor presentation, while Code Mode receives output-schema types and exact runtime JSON. Tool authors must treat the canonical value as their programmatic API and put display-only formatting in the renderer. + +The worker performs bounded-depth flat-wire transport and lossless validation but does not make intermediate values cheap or durable. Outer overflow is an explicit failed run, and error handling remains intentionally human-guided rather than a versioned code union. + +## Known Limitations and Deferred Work + +- Subagent and workflow

失败。该错误包含标准的 `Error` 消息和确切的 `toolName`，并有意省略 `ToolFailure.info`、错误代码与 Native 内容。这是一项用于控制流的异常契约，而不是供程序分类的失败联合。 + +绑定参数与绑定返回值会在不可信 worker 协议的两端重新校验为无损 JSON，且不设字节上限。每个分离后的值在通过结构化克隆跨越边界前，都会编码为扁平的前序 token 流，其传输结构的嵌套深度有界；接收方再以迭代方式重建该值。因此，有效应用数据的嵌套深度既不受 JavaScript 调用栈深度上限限制，也不受特定平台对嵌套结构化克隆施加的上限限制。模块初始化时，worker 会捕获自身 JavaScript 运行域中 `Array.prototype` 和 `Object.prototype` 的引用、仅用于识别其他运行域普通容器原型的原生函数源码内建方法，以及 JSON 边界用于结构处理和计量的全部内建方法。属性写入使用原型为 null 的属性描述符；内部的数组与集合操作直接调用捕获的方法，不会访问可变的全局或原型槽位。因此，即使模型代码替换 `Object.keys`、`Array.isArray`、集合方法、字符串方法或 `Buffer.byteLength` 等辅助方法，重写内建原型的构造函数槽位，或向 `Object.prototype` 添加形如属性描述符的字段，也不会改变校验、协议传输或字节计量。面向其他运行域的原生函数源码检查仍会拒绝由用户编写、冒充 `Object` 或 `Array` 的构造函数。为保持依赖轻量，运行时 seam 将结构等价类型命名为 `CodeJsonValue`，从而无需依赖会话侧拥有的规范类型；生成的 SDK 和工具 API 则使用 `JsonValue`。这些值不会经过提示词截断、上下文输出落盘或持久化。因此，程序可以完整筛选已经采集的搜索、工作流、任务、文件系统与 MCP 值，同时提供方和执行器的采集上限仍会实际生效。 + +### 外层结果与输出账本 + +运行时接受以任意 JSON 类型为根的精确无损完成值。返回 `undefined` 表示省略完成值；返回 `null` 则是显式结果。`run_code`

+`WorkerCodeRuntime` 以可配置的 `maxOutputBytes` 取代彼此独立的日志与值上限，默认值为 `67_108_864` 字节。worker 会将已捕获日志序列化为 JSON 字符串后的精确字节数计入账本，并在发送终态消息前，根据组合账本的剩余额度预检分离后的完成值或程序异常。因此，即使抛出的字符串或堆栈极大，通过 worker 端口的也只会是固定的 `output-limit` 诊断。宿主侧会针对伪造流量以及 worker 无法观察的原生管道写入，重复执行这套不可信对端计账。固定的 `CodeRunResult` 字段名、花括号、有界的错误类型标签及后续展示空白有意不计入这份可变负载账本。这两个阶段都不会实际生成超出上限的完成值序列化结果。结果不超过上限时会保持精确。完成值无法通过无损 JSON 快照时，以 `invalid-output`

Combining local recording with attachment upload or pull-request editing also gives a media task unrelated remote-write authority. + +## Decision + +The repository provides the [`record-browser-gif`](../../../skills/record-browser-gif/SKILL.md) skill for local browser-demo artifacts.

OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:"api" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:"events"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, async execute(args) { … } }))` to give yourself a new tool — it becomes callable on your NEXT step.

A tool's `execute` MUST return an ARRAY of content blocks, e.g. `return [{ type: 'text', text: someString }]` — never a bare string.

A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Mounts can COMPOSE: one plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically on unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned on unmount) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.", "parameters": { "type": "object", "properties": { @@ -438,6 +440,7 @@ "description": "The COMPLETE task list, replacing any previous list.", "items": { "type": "object", + "additionalProperties": true, "properties": { "content": { "type": "string", @@ -512,7 +515,7 @@ }, { "name": "workflow", - "description": "Run a JavaScript workflow script that orchestrates subagents at scale.

The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`).

Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const — no oneOf/pattern/format/numeric bounds) it resolves to the validated object.

Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.

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

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

Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, async execute(args) { … } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'boolean'|'object'|'array', required?: true, description?, enum?, items?, properties? }; a JSON-Schema-style { type: 'object', properties, required: […] } wrapper and type 'integer' are also accepted and normalized. A tool's `execute` MUST return an ARRAY of content blocks, e.g. `return [{ type: 'text', text: someString }]` — never a bare string. Mounts can COMPOSE: one plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically on unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined.

Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, async execute(args) { … } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'boolean'|'object'|'array', required?: true, description?, enum?, items?, properties? }; a JSON-Schema-style { type: 'object', properties, required: […] } wrapper and type 'integer' are also accepted and normalized. A tool's `execute` MUST return an ARRAY of content blocks, e.g. `return [{ type: 'text', text: someString }]` — never a bare string. Mounts can COMPOSE: one plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically on unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`.

OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Mounts can COMPOSE: one plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically on unmount.

Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned on unmount) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock).

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

Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's text output as a string. Tool arguments must be JSON-serializable.\n- A FAILED tool call rejects with an `Error` carrying the tool's error text — `try/catch` it to handle and continue.\n- Calls execute sequentially, even under `Promise.all`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ndeclare const tools: {\n /** Execute a bash command (`bash -c`) and return its stdout/stderr.

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

Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, async execute(args) { … } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'boolean'|'object'|'array', required?: true, description?, enum?, items?, properties? }; a JSON-Schema-style { type: 'object', properties, required: […] } wrapper and type 'integer' are also accepted and normalized. A tool's `execute` MUST return an ARRAY of content blocks, e.g. `return [{ type: 'text', text: someString }]` — never a bare string. Mounts can COMPOSE: one plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically on unmount.

(2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld.

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

Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true.

You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Calls execute sequentially, even under `Promise.all`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n /** Execute a bash command (`bash -c`) and return its stdout/stderr.

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

OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, async execute(args) { … } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'boolean'|'object'|'array', required?: true, description?, enum?, items?, properties? }; a JSON-Schema-style { type: 'object', properties, required: […] } wrapper and type 'integer' are also accepted and normalized. A tool's `execute` MUST return an ARRAY of content blocks, e.g. `return [{ type: 'text', text: someString }]` — never a bare string. Mounts can COMPOSE: one plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically on unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`.

Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld.

Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true.

Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Calls execute sequentially, even under `Promise.all`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n /** Execute a bash command (`bash -c`) and return its stdout/stderr.

OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Mounts can COMPOSE: one plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically on unmount.

Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned on unmount) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n cordis_mount: {\n /** Body of an async JS function; must `return` the plugin to mount. */\n code: string;\n } & Record;\n /** Dispose a plugin previously mounted with cordis_mount, by id.

The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`).

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

Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"Body of an async JS function; must `return` the plugin to mount."}},"required":["code"]}},{"name":"cordis_unmount","description":"Dispose a plugin previously mounted with cordis_mount, by id.

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

Timeout is reported independently of final exit status; nonzero exit remains a model-interpreted result rather than `isError`. Truncation links a safe complete spill file or reports it unavailable. Only infrastructure failures such as spawn errors and aborts produce `isError`. +The canonical success is `{ kind: 'foreground', ...BashRunResult }` for a completed foreground process or `{ kind: 'background', taskId }` for a published task. The Native renderer preserves the text above, including exactly `started background task `; programmatic consumers use the typed fields without parsing those strings. Executor stream caps remain acquisition limits on `BashRunResult` and carry their spill paths. + When `run_in_background` is true, this plugin preflights `ctx.tasks.start()` before spawning, registers the calling agent as owner, and adapts the returned `BashProcess` handle into generic cancel/done/incremental-output hooks. The task runtime owns ids, cross-session isolation, completion notices, waiting, and disposal cleanup; this plugin only maps bash exit/sandbox facts into task output and outcome detail. `enableRunInBackground: false` removes the parameter and rejects a forced background call at execution time. ## UI presentation diff --git a/packages/bash/tool-bash/src/index.ts b/packages/bash/tool-bash/src/index.ts index 094e594661..81770b1595 100644 --- a/packages/bash/tool-bash/src/index.ts +++ b/packages/bash/tool-bash/src/index.ts @@ -11,8 +11,9 @@ import { Service, type Context } from 'cordis' import z from 'schemastery' import { isAbsolute, resolve as resolvePath } from 'node:path' -import { defineTool } from '@deepseek-ai/dsh-tools' +import { defineTool, TOOL_ABORTED } from '@deepseek-ai/dsh-tools' import type { GenericCallView, TerminalCallView, ToolExecution, ToolResult, ToolResultView } from '@deepseek-ai/dsh-tools' +import { HarnessError } from '@deepseek-ai/dsh-llm' import type { Agent } from '@deepseek-ai/dsh-agent' import type {} from '@deepseek-ai/dsh-session-persistence' import type {} from '@deepseek-ai/dsh-system-prompt' @@ -22,7 +23,7 @@ import type { SandboxExecutionPolicy, SandboxMode } from '@deepseek-ai/dsh-sandb import { ESCALATION_TARGETS, approveEscalation, canonicalPath, validateEscalationArgs } from '@deepseek-ai/dsh-sandbox' import type { SandboxPolicyService } from '@deepseek-ai/dsh-sandbox-policy' import { DSH_ENV_PREFIX } from '@deepseek-ai/dsh-bash' -import type { DshEnvironment, DshEnvironmentKey } from '@deepseek-ai/dsh-bash' +import type { BashRunResult, DshEnvironment, DshEnvironmentKey } from '@deepseek-ai/dsh-bash' import { DSH_HOME_ENV, resolveDshHome } from '@deepseek-ai/dsh-paths' import { processOutcome } from './background.ts' import { parseExitStatus, renderProcessRead, renderResult } from './render.ts' @@ -206,7 +207,7 @@ export class BashEnvRegistry extends Service { } } -/** Parsed tool args; execute validates value constraints absent from SchemaSpec. */ +/** Parsed tool args; execute validates value constraints absent from ParameterSchemaSpec. */ interface BashToolArgs { command: string description: string @@ -318,6 +319,38 @@ function resolveWorkdir( return modelWorkdir } +/** Detach the executor DTO from readonly seam interfaces into plain JSON data. */ +function canonicalBashResult(result: BashRunResult) { + const output = (stream: BashRunResult['stdout']) => ({ + text: stream.text, + truncated: stream.truncated, + ...stream.spillPath !== undefined ?

The chat view is this package's own ring entry; other plugins (ui-trajectory) contribute tabs through plain `ctx.slots.register` — the former package-local view registry (`registerView`/`ViewEntry`/`ConversationViewMap` and the chrome attachment table) is retired, with per-view chrome dissolved into the view components themselves.

The chat entry declares the keyed `'conversation.chat.toolview'` hole (session scope; the key space is runtime-open); its render site dispatches per row via `entryKey: toolName` with `GenericToolCard` as the call-site `fallback`. The owner payload is the uniform `ToolRowOwnerProps` (`callId`/`toolName`/`block`/`openDetails`) and `ToolRowProps` pre-composes it with the session standard kit. A registrant is a plain plugin: `ctx.slots.register({ name: 'conversation.chat.toolview', key: '', inject? }, Row)` with `inject: ['slots', 'conversation']` as the load-order seam (apply mounts ConversationService after the chat registration, so the service being present guarantees the slot is declared); session differentiation happens inside the component (`useSessions` reading `parentId` — the bash sample is the third-party-posture exemplar).
