+# Agent Note: Session working directory
+
+Status: implemented
+
+English | [中文](2026-09-13-session-working-directory.zh.md)
+
+## Problem
+
+A fixed Session creation directory cannot represent a task that changes checkout during its conversation. Independent tools resolving paths from different sources can read and write different projects, while changing the process directory also affects unrelated Sessions. Putting mutable directory information in the system prompt changes the reusable prompt prefix.
+
+## Decision
+
+`dsh-working-directory` owns one logged effective directory per Session. Its projection initializes from the immutable original project and folds `working-directory/change`; consumers read that owner instead of deriving execution paths from the header or sandbox root. Directory changes validate through the filesystem provider, serialize within the Session, and publish only after the new directory is available.
+
+The built-in `working_directory({ cd? })` tool reads or changes the directory. Required user-context snapshots carry the current value; each committed change attempts to queue a notice through the ordinary Agent inbox. Cancellation or disposal may discard unadmitted notices while the directory event survives for subsequent requests. The original project is the recovery destination when the selected directory disappears. Missing recovery destinations produce an error. Write permissions remain independent.
+
+Subagents capture the parent's current directory or an explicit override and commit their selected directory after inherited history. Existing processes, terminals, and persistent shells keep their process-local directory. Project instructions, skills, and completion follow the effective directory without changing Session identity, grouping, or runtime composition.
+
+File links and command directory labels use result metadata captured when each operation runs, so historical rows remain correct after later directory changes.
+
+## Alternatives considered
+
+**Rewrite the Session header.** The header is immutable identity metadata used by storage, grouping, and permission roots. Rewriting it would conflate current execution state with the original project.
+
+**Let worktree tools own directory state.** Ordinary directory changes, filesystem tools, and subagents need the same value. A Git-specific owner would duplicate selection and recovery.
+
+**Change the process directory or synchronize every shell.** Concurrent Sessions and existing subprocesses have independent lifetimes. A Session change affects new directory-based operations, while a shell's `cd` remains local.
+
+**Keep directory text in the system prompt.** Mutable operational context belongs after retained history, using the same user-context mechanism as permission state.
+
+## Consequences
+
+The runtime exposes one directory owner and preserves the original project. Consumers migrate together, including filesystem, shell, instructions, skills, subagents, and both SDKs. Directory existence can change outside the harness, so validation and logged recovery occur at use. Required runtime context remains visible even when optional context is suppressed.
+
+Verification covers independent Sessions, relative changes, replay, cancellation, recovery, tool disposal, user-context rendering, provider inheritance, and real directory-based operations.

+
+## Problem
+
+固定的 Session 创建目录无法表示在对话中切换检出目录的任务。各工具从不同来源解析路径时,可能读写不同项目;改变进程目录还会影响其他 Session。把可变目录信息放入系统提示词会改变可复用的提示词前缀。
+
+## Decision
+
+`dsh-working-directory` 拥有每个 Session 的一个日志化有效目录。投影从不可变的原始项目初始化,并折叠 `working-directory/change`;消费者读取该服务,而不是从 header 或沙箱根目录派生执行路径。目录变更通过文件系统 provider 验证,在 Session 内串行执行,并只在新目录可用后发布。
+
+内置 `working_directory({ cd? })` 工具读取或改变目录。必需的用户上下文快照携带当前值;每次已提交变更都会尝试通过普通 Agent 收件箱排入通知。取消或销毁可能丢弃尚未进入请求的通知,但目录事件仍然保留,供后续请求使用。所选目录消失时恢复到原始项目。恢复目录也消失时返回错误。写权限保持独立。
+
+子代理捕获父代理当前目录或显式覆盖值,并在继承历史之后提交选定目录。已有进程、终端和持久 shell 保留进程局部目录。项目指令、技能和补全跟随有效目录,不改变 Session 身份、归属或运行时组合。
+
+文件链接与命令目录标签使用各次操作执行时记录的结果元数据,因此后续目录变更不会使历史记录指向错误的位置。
+
+## Alternatives considered
+
+**改写 Session header。** header 是存储、归属与权限根目录使用的不可变身份元数据。改写它会混淆当前执行状态与原始项目。
+
+**让 worktree 工具拥有目录状态。** 普通目录变更、文件系统工具和子代理需要同一个值。Git 专用 owner 会重复实现选择与恢复。
+
+**改变进程目录或同步所有 shell。** 并发 Session 与已有子进程具有独立生命周期。Session 变更影响新的目录相关操作,shell 内的 `cd` 则保持局部。
+
+**把目录文本留在系统提示词中。** 可变操作上下文应位于保留历史之后,复用权限状态的用户上下文机制。
+
+## Consequences
+
+运行时提供一个目录 owner,并保留原始项目。消费者一起迁移,包括文件系统、shell、指令、技能、子代理和两种 SDK。目录可能在 harness 之外消失,因此在使用时执行验证和日志化恢复。即使可选上下文被禁用,必需运行时上下文也仍然可见。
+
+验证覆盖 Session 相互独立、相对路径变更、回放、取消、恢复、工具卸载、用户上下文渲染、provider 继承和真实目录操作。

## Capability seams
A **seam** is a swappable capability with three roles: a **Service Definition** declaring the interface, a **Service Provider** implementing it, and a **Consumer** using it, commonly a model-facing tool. A package may combine roles, but one role alone is not a seam; adding a capability means designing all three ([capability graph](capability-seams.md)).

+
+## Table of Contents
+
+- [Declaration](#declaration)
+- [Compatibility](#compatibility)

+- [Dev Note](#dev-note)
+
+
+## Declaration
+
+```yaml persistence-change

+id: 2026-09-13-working-directory

+ decision: same-version
+```
+
+
+## Compatibility
+
+Existing Session headers and events remain valid. The new event is required on read: older builds that do not know working-directory/change refuse logs containing it. The event vocabulary grows without changing the structural Session format.
+
+
+## Verification
+
+Focused working-directory and system-prompt suites pass 113 tests with per-file 100% coverage. Keyless headless replay verifies changes, recovery, user-context notices, and a stable system prompt.
+
+
+## Dev Note
+
+None.

+# Working Directory
+
+English | [中文](working-directory.zh.md)
+
+A Session's active directory is owned by [`dsh-working-directory`](../../packages/session/working-directory/README.md). The immutable header identifies the original project; `working-directory/change` records the effective directory used by later directory-based operations. The generated [persistence catalog](../persistence-catalog.md) owns the event declaration.
+
+## Directory selection
+
+`ctx.workingDirectory.get(session)` reads the logged value. `ensure(agent)` validates it and restores the original project when the directory disappeared. `set(agent, path)` validates and records a requested change. Sessions without a header directory use the configured runtime fallback; an unavailable fallback produces an error.
+
+Changes are local to one Session. Relative filesystem operations, newly started processes, instruction discovery, skills, and file completion use the active directory. Existing terminals and persistent shells retain their own directories. Sandbox writable roots and project membership remain anchored to the original project.
+
+## Model context
+
+The initial value and subsequent current values reach the model as required user-context snapshots, even when optional runtime context is disabled. Each committed change attempts to queue a notice through the ordinary Agent inbox; cancellation or disposal can discard notices before request admission. The directory event survives, and the next admitted request receives the current value. Directory context never enters the system prompt. [`working_directory`](../../packages/session/tool-working-directory/README.md) exposes one optional `cd` argument.
+
+
+
+
+
+## Cordis API
+
+Generated from source by `scripts/gen-cordis-catalog.ts` (verified fresh by `pnpm run verify-cordis-catalog` in doc-sync; regenerate with `pnpm run gen-cordis-catalog`) — the language sides differ only in locale-specific paired document paths. Signature blocks use a `ts cordis-catalog` fence and keep the original source JSDoc; dispatch modes are defined in the [primer](../cordis-primer.md#dispatch-modes), and the framework-inherited `ctx` API lives in [cordis-api/inherited.md](../cordis-api/inherited.md).
+
+
+
+### `ctx.workingDirectory` — `WorkingDirectoryService`
+
+One owner for each Session's effective directory and its model-visible changes.
+

+# 工作目录
+
+[English](working-directory.md) | 中文
+
+Session 的当前目录由 [`dsh-working-directory`](../../packages/session/working-directory/README.zh.md) 拥有。不可变 header 标识原始项目;`working-directory/change` 记录后续目录相关操作使用的有效目录。生成的[持久化目录](../persistence-catalog.zh.md) 拥有事件声明。
+
+## 目录选择
+
+`ctx.workingDirectory.get(session)` 读取日志中的值。`ensure(agent)` 验证它,并在目录消失时恢复原始项目。`set(agent, path)` 验证并记录请求的变更。header 没有目录的 Session 使用配置的运行时回退目录;回退目录不可用时返回错误。
+
+变更仅影响一个 Session。相对路径文件系统操作、新启动的进程、指令发现、技能和文件补全使用当前目录。已有终端和持久 shell 保留自己的目录。沙箱可写根目录与项目归属继续绑定原始项目。
+
+## 模型上下文
+
+初始值与后续当前值通过必需的用户上下文快照到达模型,即使可选运行时上下文被禁用也不例外。每次已提交变更都会尝试通过普通 Agent 收件箱排入通知;取消或销毁可能丢弃尚未进入请求的通知。目录事件仍然保留,下一次获准进入的请求会收到当前值。目录上下文不进入系统提示词。[`working_directory`](../../packages/session/tool-working-directory/README.zh.md) 提供一个可选的 `cd` 参数。
+
+
+
+
+
+## Cordis API
+
+Generated from source by `scripts/gen-cordis-catalog.ts` (verified fresh by `pnpm run verify-cordis-catalog` in doc-sync; regenerate with `pnpm run gen-cordis-catalog`) — the language sides differ only in locale-specific paired document paths. Signature blocks use a `ts cordis-catalog` fence and keep the original source JSDoc; dispatch modes are defined in the [primer](../cordis-primer.zh.md#dispatch-modes), and the framework-inherited `ctx` API lives in [cordis-api/inherited.md](../cordis-api/inherited.md).
+
+
+
+### `ctx.workingDirectory` — `WorkingDirectoryService`
+
+One owner for each Session's effective directory and its model-visible changes.

The Client journal validates current Session event envelopes before publishing follow snapshots, live entries, or history pages. It reuses the browser-safe Session validators for required surface markers, exact replacement endpoints, earlier unique source seqs, embedded Assistant provider metadata, request-header omissions, and tool-error consistency. Invalid records fail without field stripping or normalization; range membership and source existence remain durable-log checks on the Host.
-Each endpoint states its activation policy. List reads only stored headers and projection-cache rows: it never calls per-session stat or opens a cold Session body. A current-format cache identity may supply every list hint; a lifecycle-matching predecessor cache may supply only its version-compatible title as a stale display fact, never as an authoritative fold seed. Search, attachment, history pages, log following, skill discovery, and workspace-path opening can inspect persistence without activating an Agent; `canOpenWorkspacePath()` reports native-opening availability without addressing a Session. Cancellation requires live state; queue mutation, model, rename, prompt, and file-reference operations may resolve or resume an ordinary Session. Prompt rejects content with neither non-whitespace text nor an attachment before resolving the Agent or appending Session events; queue edits accept only non-empty text content. Prompt admission consumes opaque receipts from the injected [`fileUploads`](../../client/file-upload/README.md) Host service and resolves every same-Agent receipt before sending the complete ordered content list through `ctx.attachments`. Prompt retries whose `requestId` is already queued or logged return the original acceptance without inserting another message. Create and fork are the only operations that create a new Agent directly. The service applies one preset-aware resume policy and subagent ownership fence to its own methods and to the Typert Agent and Session lookups used by other Remote namespaces. Queue mutation has one narrow exception: a live child whose current projected identity is continuable and comes from its own non-seed suffix accepts the ordinary Edit, Remove, and QueueDock Steer actions across both inbox destinations. One-shot, missing, unknown, corrupt, seed-only, or cold children remain rejected without resume. The skill catalog uses a live Agent when present or the recorded preset's standing scope when cold, so listing never starts an Agent. The authenticated delivery routes use `workspaceDesktop()` for the serving Host name and file-manager behavior. `openWorkspacePath({ path, action: "reveal" })` delegates file-manager navigation to the native adapter; omitting `action` opens the file-type association, including HTML and SVG. Both operations require the composed filesystem to map the requested Host path to the same canonical process path; unmapped remote paths are refused before a native command runs. `session.projections` reads one complete baseline through a live-preferred Session observation without activating an Agent. It returns null for a missing Session and serves any registered projection keys. The Client exposes shared values and explicit-read state through `projectionsBySession`; domains select their own keys. Session-list summaries carry `agentAvailable`, updated through existing summary and status events independently of durable projections. Initial reads and live projection frames use the same sequence ordering.

One-shot, missing, unknown, corrupt, seed-only, or cold children remain rejected without resume. The skill catalog uses a live Agent's effective working directory and scoped registry when present. Cold listing uses the projected current directory, falling back to the recorded origin and then the configured directory default. It retains the preset standing scope without activating an Agent. The authenticated delivery routes use `workspaceDesktop()` for the serving Host name and file-manager behavior. `openWorkspacePath({ path, action: "reveal" })` delegates file-manager navigation to the native adapter; omitting `action` opens the file-type association, including HTML and SVG.

Session-list summaries carry `agentAvailable`, updated through existing summary and status events independently of durable projections. Initial reads and live projection frames use the same sequence ordering.
Host list generation yields between complete rows only when its configured work slice is exhausted; cheap remaining work returns without a forced yield. Request cancellation is checked per row and after each yield and rejects without partial results. Each row is synchronous; the list does not promise one cross-Session snapshot. A Session already queued as cold remains a cached row if it attaches during a yield: Client in-flight mutation replay corrects its availability, and sequenced projections supersede cached hints.

Web fetch runs without per-call approval; its provider rejects non-public destinations. Feedback stays in the Session log.

-Use `dsh --profile sdk-minimal` when an SDK client needs a small, explicit coding-agent runtime. By default, the profile advertises only a platform-selected persistent shell, persists sessions as uncompressed JSONL, and selects the model from the SDK initialization request. It supplies a complete Cordis tree and deliberately excludes `dsh-base`, Web, settings, managed credentials, telemetry, compaction, filesystem tools, workspace instructions, skills, jobs, and subagents. Its danger-full-access policy lets the shell modify any path available to the process, so use it only with an isolated workspace.

## Use this package
+Changing the Session's working directory reloads the applicable project instruction chain before the next request.
+
Mount this plugin when agents should work from the workspace's own instruction files. `dsh-base` already includes it with a 65,536-byte budget, so base-backed profiles only need to replace the row when they want another `maxBytes`; providerless trees load nothing until a filesystem provider is present.

## 使用本包

当 agent 需要依据工作区自身的指令文件工作时,挂载此插件。`dsh-base` 已包含它并给予 65,536 字节预算,因此基于 base 的 profile 仅在需要其他 `maxBytes` 时替换该配置行;没有文件系统提供方的树加载不到任何内容,直到提供方出现。

#### What the model sees
-For each step, the loop sends the session's derived messages and visible tool schemas. Non-empty `system/message` nodes carry the prompt, with the latest as the effective version; an empty rendering clears all prompt versions from derived history. It supplies `provider`, `model`, and `cwd` variable values but no additional fixed prose. The request header always records active tools. Comparing their names with the preceding header emits one `developer/message` for additions and removals, independently of model capability; additions reference the new header. Requests also carry `Session.toolHistory()` for the LLM runtime to construct provider declarations.

#### What the model sees
-First-party sections render the harness identity, deployment persona prefix (including the model-name introduction), reusable instructions (including the generated tools SDK and structured-output guidance), then the environment-bearing suffix: harness source (`10000`), Web surface (`10100`), and deployment persona suffix (`10200`). External section orders and assembly listeners remain authoritative. `includeHarnessIdentity: false` omits only that fixed opener. Empty sections disappear; scoped sections and variables can shadow globals for one agent. The `system-prompt/assemble` waterfall determines the delivered prompt and tool schemas unless one effective section declares itself complete — that exact section then becomes the whole system prompt while the waterfall's contexts, tools, and variables remain. The rendered prompt reaches the model as a system-role message of derived history — surface node 0, or the latest system node after an in-history update — neither the loop request nor `request/header` carries a separate `system` field. If the complete rendering is empty, the loop clears every active system node through logged empty replacements, so no older prompt remains in model history. Ordered dynamic contexts are separate from sections and become sourced user-role snapshots only when present; `includeRuntimeContext: false` or a scoped suppressor removes them all.

## Use this package
+Each `run_code` program captures the Session's current working directory when it starts. A nested directory change affects subsequent tool calls, while the running program keeps its initial directory.
+
Mount `dsh-tools` wherever agents call tools: it provides `ctx.tools`, the registry every tool plugin registers into and the loop dispatches through. Registering a tool is enough to make it visible — the registry feeds its schemas into the system-prompt assembly automatically.

The Node default is 120,000 ms with a 600,000 ms cap, including nested tool and approval waits. A wider `sandbox_permissions` mode requires a non-empty `justification` and approval before the program starts. The schema asks the model to write that reason in the current user's language.

## Use this package
+Relative paths use the Session's current working directory. A directory change affects subsequent reads and mutations without changing sandbox permission roots. Successful results return the canonical absolute path from `fs.processPath`, and root result metadata retains that operation-time path for replay and navigation.
+
Mount the tools after a `ctx.fs` backend and, for read-before-write/edit behavior, the policy plugin. The model then gets line-numbered reads, atomic writes and edits, and — with an attachment store mounted — image reads; every result is capped, and failures carry stable codes with recovery instructions.

## Use this package
+Hook processes and their payload `cwd` use the Session's current working directory when each hook point starts. `CLAUDE_PROJECT_DIR` follows it unless `projectDir` is configured.
+
Mount this package, point `configPath` at your hook config, and the hooks you already have start firing at the corresponding moments in agent runs. There is nothing else to set up before the first hook works.
### When to choose it
@@ -65,7 +67,7 @@ The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-a
### How hooks run and fail
-- Hooks run in your project directory — the agent's session workspace — so `pwd` and relative paths in your hooks refer to your project, not the server's launch directory.
+- Hooks run in the agent's current Session directory; `pwd`, payload `cwd`, and relative paths agree.
- `${CLAUDE_PLUGIN_ROOT}` and `${CLAUDE_PROJECT_DIR}` in command strings are replaced from your config, and `CLAUDE_PROJECT_DIR` is set for every hook process.
- One config applies to the whole process: it is read once at startup, and a relative `configPath` resolves from the directory that launched the process.
- Hooks on the same event run one after another, in config order.

+- 钩子在 agent 的 Session 当前目录中运行;`pwd`、载荷中的 `cwd` 与相对路径保持一致。
- 命令字符串中的 `${CLAUDE_PLUGIN_ROOT}` 与 `${CLAUDE_PROJECT_DIR}` 会按你的配置替换,且每个钩子进程都会设置 `CLAUDE_PROJECT_DIR`。
- 一份配置应用于整个进程:启动时只读取一次,相对 `configPath` 从启动进程的目录解析。
- 同一事件上的钩子按配置顺序逐个运行。

## Use this package
+Hook processes and their payload `cwd` use the Session's current working directory when each hook point starts.
+
Mount this package, point `configPath` at your `hooks.json`, and the hooks you already have start firing at the corresponding moments in agent runs. There is nothing else to set up before the first hook works.

### How hooks run and fail
-- Hooks run in your project directory — the agent's session workspace — so `pwd` and relative paths in your hooks refer to your project, not the server's launch directory.
+- Hooks run in the agent's current Session directory; `pwd`, payload `cwd`, and relative paths agree.
- One config applies to the whole process: it is read once at startup, and a relative `configPath` resolves from the directory that launched the process.
- Only synchronous command hooks run; an `async: true` or non-command hook is skipped with a warning.
- Hooks on the same event run one after another, in config order.

## Use this package
+Queries use the Session's current working directory as their workspace root. Changing directory affects subsequent queries without changing an already running server's root.

An agent uses `lsp` when textual matches are ambiguous or before a change that needs precise definitions, implementations, or references; the tool's prompt guidance tells it to prefer `search`/`read` for ordinary navigation.

## Use this package
+`HarnessSession.getWorkingDirectory()` reads the effective directory; `setWorkingDirectory(path)` changes it and returns the validated absolute path. Either method creates an unknown Session without starting a model turn. Relative paths use the Session's current directory. Origin metadata, permissions, and existing processes remain unchanged. `HarnessClient` exposes the same methods with a leading `sessionId` argument.
+
Use this client when TypeScript code must drive a complete Harness runtime from another process and you can name the runtime executable explicitly. The common path is minimal: construct a `DeepSeekHarness` with a launch spec, run prompts, and close it so the child process is always reaped.

## 使用本包
+`HarnessSession.getWorkingDirectory()` 读取有效目录;`setWorkingDirectory(path)` 修改目录并返回校验后的绝对路径。两个方法都可创建未知 Session,而不启动模型轮次。相对路径以 Session 当前目录解析。起始目录元数据、权限与已有进程保持不变。`HarnessClient` 提供同名方法,并以 `sessionId` 作为首个参数。
+
当 TypeScript 代码需要从另一进程驱动完整 Harness 运行时、且你能显式指名运行时可执行文件时,使用本客户端。常用路径极简:用启动规格构造 `DeepSeekHarness`,运行提示词,然后关闭它,使子进程总能被回收。

## Use this package
+`session/working-directory/get` accepts `{ sessionId }`; `session/working-directory/set` accepts `{ sessionId, path }`. Both return `{ cwd }` and create an unknown Session without starting a model turn. Reads recover missing directories through the working-directory service; changes preserve origin metadata and permissions, and reach the model through logged user context.
+
Mount this plugin when a runtime must serve SDK clients: add it to a `cordis.yml` that composes the agent service, boot the runtime, and clients connect over stdio. The common path is explicit — the plugin needs the `agents` service; every other capability comes from the surrounding tree.

## 使用本包
+`session/working-directory/get` 接收 `{ sessionId }`;`session/working-directory/set` 接收 `{ sessionId, path }`。两者均返回 `{ cwd }`,并可创建未知 Session,而不启动模型轮次。读取通过工作目录服务恢复缺失目录;修改保留起始目录元数据与权限,并通过已记录的用户上下文告知模型。

当运行时必须服务 SDK 客户端时挂载本插件:把它加入组合了 agent 服务的 `cordis.yml`,启动运行时,客户端即可通过 stdio 连接。常用路径是显式的——插件需要 `agents` 服务;其余每个能力都来自外围插件树。

+Read the Session’s current directory or enter an existing directory with the same tool. Relative changes use the current directory. The returned absolute path can be passed to other tools.

+
+
+## Use this package
+
+Mount alongside `tools` and `workingDirectory`. Call `working_directory({})` to read or `working_directory({ cd: "src" })` to change directory. The tool has no configuration fields.
+
+```yaml
+- name: '@deepseek-ai/dsh-tool-working-directory'
+```
+
+-----
+
+
+## Understand the implementation
+
+
+Implementation internals — click to expand
+
+The tool delegates validation, recovery, persistence, and context notices to the directory owner. Its canonical result contains `cwd`; native rendering returns that path. The generic tool card displays the arguments and result without a separate GUI renderer.
+
+No runtime invariant companion is published because the tool delegates all directory state and mutations to `workingDirectory`.
+
+
+
+-----
+
+
+## Further Exploration
+
+- [Working directories](../../../docs/subsystems/working-directory.md) — shared runtime behavior.
+- [Session group](../README.md) — durable Session services.
+- [Testing](../../../docs/testing.md) — composition and replay verification.
+
+-----
+
+
+## Model Experience
+
+### Tool schema and result
+
+#### What the model sees
+
+The [tool catalog](../../../docs/tool-catalog.md#deepseek-aidsh-tool-working-directory) defines the optional `cd` argument and canonical `cwd` result. Directory notices are owned by `dsh-working-directory`.
+
+#### Token effect
+
+The registered schema and returned path contribute tokens when the tool is available and invoked.
+
+#### KV Cache effect
+
+Changing tool availability changes its schema context. A tool call appends ordinary call and result history without replacing prior messages.
+
+## Known Limitations and Deferred Work
+
+
+
+- **Calling Session required** — the tool requires an Agent and changes neither existing processes nor write permissions.
+
+
+### Dev Note
+
+
+Working context for maintainers — click to expand
+
+None.

+## Summary
+
+Change one Session’s working directory while existing processes retain theirs. The selected directory survives replay and appears in user context. A missing directory restores the original project when it remains available.

+
+-----
+
+
+## Use this package
+
+Mount alongside `fs`, `sessionProjections`, and `systemPrompt`. `defaultDirectory` selects an absolute fallback for Sessions without an original directory; omission uses the launch directory. See the [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-working-directory).
+
+```yaml
+- name: '@deepseek-ai/dsh-working-directory'
+```
+
+-----
+
+
+## Understand the implementation
+
+
+Implementation internals — click to expand
+
+The Session projection owns the effective directory and exposes it in Session observations, so cold readers can use it without activating an Agent; the header continues to identify the original project. Changes serialize per Session, validate through the filesystem provider, check cancellation and Agent lifetime, commit an event, and queue a user-context notice. If notice queuing fails after commit, the operation returns the committed directory and logs a warning; the next request or resume still receives the required directory context. Prompt assembly validates the current directory before publishing its required context contribution. Existing processes and sandbox grants keep their independent ownership. The [service implementation](src/index.ts) defines the API.
+
+No runtime invariant companion is published because the service reads its only directory state from the Session projection and checks filesystem validity at use.
+
+
+
+-----
+
+
+## Further Exploration
+
+- [Working directories](../../../docs/subsystems/working-directory.md) — shared runtime behavior.
+- [Session group](../README.md) — durable Session services.
+- [Testing](../../../docs/testing.md) — composition and replay verification.
+
+-----
+
+
+## Model Experience
+
+### Working directory context
+
+#### What the model sees
+
+The current value is `Current working directory: .` Each committed change, including automatic recovery, attempts to queue a user-context notice through the ordinary Agent inbox. Cancellation or disposal may discard unadmitted notices; the durable directory remains available to the next request. Directory context stays outside the system prompt and remains enabled when optional runtime context is disabled.
+
+#### Token effect
+
+The initial snapshot and changed values add user-context tokens; unchanged snapshots are not repeated.
+
+#### KV Cache effect
+
+Directory transitions append context without replacing the stable system-prompt prefix. A changed directory or recovery creates new context after retained history.
+
+## Known Limitations and Deferred Work
+
+
+
+- **Missing original project** — recovery fails when the original directory is unavailable; the service does not choose or recreate a repository. Existing shells retain their process-local directories.
+
+
+### Dev Note
+
+
+Working context for maintainers — click to expand
+
+None.

+## 概述
+
+改变一个 Session 的工作目录,同时保留已有进程各自的目录。所选目录可通过回放恢复,并出现在用户上下文中。当前目录消失时,只要原始项目仍然存在,就恢复到原始项目。
+
+## 目录
+
+- [使用此包](#use-this-package)
+- [理解实现](#understand-the-implementation)
+- [进一步阅读](#further-exploration)
+- [模型体验](#model-experience)
+- [已知限制与后续工作](#known-limitations-and-deferred-work)
+- [开发备注](#dev-note)
+
+-----
+
+
+## 使用此包
+
+与 `fs`、`sessionProjections` 和 `systemPrompt` 一起挂载。`defaultDirectory` 为没有原始目录的 Session 指定绝对回退目录;省略时使用启动目录。参见[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-working-directory)。
+
+```yaml
+- name: '@deepseek-ai/dsh-working-directory'
+```
+
+-----
+
+
+## 理解实现
+
+
+实现细节 — 点击展开
+
+Session 投影拥有当前目录,并通过 Session observation 暴露它,因此冷态读取方无需激活 Agent 即可使用;header 继续标识原始项目。每个 Session 的变更串行执行,通过文件系统 provider 验证,并检查取消状态与 Agent 生命周期,提交事件后排入用户上下文通知。若提交后通知入队失败,操作仍返回已提交的目录并记录警告;下一次请求或恢复仍会收到必需的目录上下文。提示词组装在发布必需的上下文条目前验证当前目录。已有进程与沙箱授权继续由各自的服务拥有。[服务实现](src/index.ts) 定义 API。
+
+不发布 `./invariant` 伴生模块,因为服务从 Session 投影读取唯一的目录状态,并在使用时检查文件系统有效性。
+
+
+
+-----
+
+
+## 进一步阅读
+
+- [工作目录](../../../docs/subsystems/working-directory.zh.md) — 共享运行时行为。
+- [Session 包组](../README.zh.md) — 持久化 Session 服务。
+- [测试](../../../docs/testing.zh.md) — 组合与回放验证。
+
+-----
+
+
+## 模型体验
+
+### 工作目录上下文
+
+#### 模型可见内容
+
+当前值为 `Current working directory: .` 每次已提交变更(包括自动恢复)都会尝试通过普通 Agent 收件箱排入用户上下文通知。取消或销毁可能丢弃尚未进入请求的通知;持久化目录仍可供下一次请求使用。目录上下文不进入系统提示词,即使可选运行时上下文被禁用,也仍然保留。
+
+#### Token 影响
+
+初始快照与变更值增加用户上下文 token;未变化的快照不会重复。
+
+#### KV Cache 影响
+
+目录变更追加上下文,不替换稳定的系统提示词前缀。目录变化或恢复在保留的历史之后生成新上下文。
+
+## 已知限制与后续工作
+
+
+
+- **原始项目缺失** — 原始目录不可用时恢复失败;服务不会另选或重建仓库。已有 shell 保留各自进程的目录。
+
+
+### 开发备注

+
+无。

## Use this package
+A new shell starts in the Session's current working directory. Once created, its directory and environment remain independent of later Session directory changes.
+
Load this plugin in any composition where the agent should keep shell state between commands — for example long build sessions, activated environments, or scripts that export variables for later steps. It registers the `bash` tool and requires the `ctx.tools` and `ctx.terminals` services plus an owning agent session at execution time.

## Use this package
+New commands start in the Session's current working directory. Relative `workdir` values resolve from that directory; per-call overrides and background jobs do not change it.
+
Load this plugin in any composition where the agent should run bash commands: it registers the `bash` tool once an executor provider and the `dsh-shell-env` registry are mounted, and stays pending until the `tools`, `shell`, `systemPrompt`, and `shellEnv` services exist.

Sandbox policy resolves per call through `ctx.sandboxPolicy`; an escalation request goes through `ctx.approval` before anything executes, and the tool fails at load if the executor confines but no policy service is mounted.

## Use this package
+A new shell starts in the Session's current working directory. Once created, its directory and environment remain independent of later Session directory changes.
+
Load this plugin in any composition where the agent should keep PowerShell state between commands — the persistent counterpart of `dsh-tool-pwsh` for work that needs cross-call state. It registers the `pwsh` tool and requires the `ctx.tools` and `ctx.terminals` services plus an owning agent session at execution time.

## Use this package
+New commands start in the Session's current working directory. Relative `workdir` values resolve from that directory; per-call overrides and background jobs do not change it.
+
Load this plugin in any composition where the agent should run PowerShell commands — typically a Windows composition whose `ctx.shell` is backed by a PowerShell executor. It registers the `pwsh` tool once the executor provider and the `dsh-shell-env` registry are mounted.
### When to choose it

+Structured foreground and background results expose `cwd`, the executor-resolved launch directory. Persisted presentation metadata carries the same value so settled cards retain the directory used by that call. A command’s own `cd` does not change this launch value; native result text remains stdout, stderr, and status markers.

### Design philosophy
@@ -204,7 +208,6 @@ These limits define when the tool is a poor fit or needs special care. They are
- **Language mode and named-pipe capture under the Windows sandbox** — under the [Windows ACL sandbox](../../sandbox/sandbox-windows-acl/README.md), read-only pwsh starts in ConstrainedLanguage because its temp write denial makes PowerShell's AppLocker probe fail closed: `Add-Type`, non-core .NET statics (`[System.IO.*]::`, `[math]::`), COM objects, and reflection fail with "only core types" errors, and the mode cannot be lifted from inside. Workspace-write's private temp lets the probe complete, so it stays in FullLanguage unless host policy says otherwise. Both confined modes deny named-pipe opens, so a piped-stdio spawn inside a confined command fails with EPERM. The tool description teaches both contracts to the model; the backend README owns the full limitations.
- **No persistent shell** — every call starts a fresh `pwsh -Command`; the persistent-shell counterpart is [`@deepseek-ai/dsh-tool-pwsh-persistent`](../tool-pwsh-persistent/README.md), which keeps one owner-scoped pwsh alive across calls.
- **PowerShell-dialect contract** — the model must write PowerShell (native paths, `$env:` variables), not bash; there is no dialect translation.
-- **Session-cwd identity is not canonicalized** — the workdir base is the session header cwd as-is, unlike the bash tool's sandbox-root-canonicalized identity. Under a confining executor the policy's workspace root IS canonicalized (by the shared policy service), so the workdir and the confinement root can diverge when the raw session cwd differs from its canonical form — a parity gap deferred to the shared shell-tool base extraction.

- **Windows 沙箱下的语言模式与命名管道捕获**——在 [Windows ACL 沙箱](../../sandbox/sandbox-windows-acl/README.zh.md)下,只读 pwsh 以 ConstrainedLanguage 启动,因为其临时目录写入被拒绝,导致 PowerShell 的 AppLocker 探测失败并按拒绝处理:`Add-Type`、非核心 .NET 静态调用(`[System.IO.*]::`、`[math]::`)、COM 对象与反射会以 "only core types" 错误失败,且该模式无法从内部解除。workspace-write 的私有临时目录让探测完成,因此除非宿主策略另有规定,它保持 FullLanguage。两种受限模式都拒绝命名管道打开,因此受限命令内部的管道 stdio spawn 会以 EPERM 失败。工具描述把两条约定都教给模型;完整限制以后端 README 为准。
- **没有持久 shell**——每次调用都启动全新的 `pwsh -Command`;持久 shell 对应物是 [`@deepseek-ai/dsh-tool-pwsh-persistent`](../tool-pwsh-persistent/README.zh.md),它跨调用保持一个按所有者隔离的 pwsh 存活。
- **PowerShell 方言约定**——模型必须编写 PowerShell(原生路径、`$env:` 变量),而不是 bash;没有方言翻译。
-- **会话 cwd 身份未规范化**——workdir 基准就是会话头部 cwd 原样,不像 bash 工具那样以沙箱根规范化身份为准。在约束执行器下,策略的 workspace root 确实被规范化(由共享策略服务完成),因此当原始会话 cwd 与其规范形式不同时,workdir 与约束根可能分叉——这是推迟到共享 shell 工具基座抽取的对齐差距。

## Use this package
+The resolved request carries an absolute `cwd`. Creation applies that directory after inherited events and before publishing the child; its immutable header continues to record the parent's origin directory.
+
You reach this package through a provider backend, not a composition: `dsh-subagent-spawn-in-process` and `dsh-subagent-fork-in-process` each call `startInProcessRun(request, options)` and own everything around it. This page documents the lifecycle both share so you can read one backend's behavior and reason about the other.

## Use this package
+Each start accepts an optional `cwd`; relative paths resolve against the parent's current working directory, and omission captures that current directory. The child keeps its parent's origin metadata and permission roots. A child-owned directory value follows any inherited history, survives continuation and restart, and is independent of later parent changes.
+
This package is the contract every delegation setup shares. You enable it by mounting the service together with one or more provider backends and the model-facing delegation tool; from then on, an agent can delegate work and the service routes each request to the named provider.

本包是每个委派组合都共享的约定。你通过把服务与一个或多个提供方后端以及面向模型的委派工具一起挂载来启用它;此后 agent 即可委派工作,服务会把每个请求路由到具名提供方。

## Use this package
+The optional `cwd` argument selects the child's initial working directory. Relative paths resolve against the caller's current directory; omission inherits it. Existing children retain their own directories when the caller changes directory.

Mount one instance per delegation target, each with a distinct `toolName`. The tool exists exactly while its provider does, so sibling load order and provider reloads never strand it.

## 使用本包
+可选参数 `cwd` 选择子级的初始工作目录。相对路径以调用者当前目录解析;省略时继承该目录。调用者切换目录时,已有子级保留自己的目录。

每个委派目标挂载一个实例,且每个实例的 `toolName` 必须不同。工具与其提供方同时存在、同时消失,因此同级加载顺序与提供方重新加载都不会让工具悬空。

## Use this package
+A terminal without an explicit initial directory starts in the owner's current Session directory. Its sandbox permission root remains governed by Session policy.

Mount this backend when a composition needs persistent shell sessions — state such as cwd, exported variables, functions, or running interactive children must survive across tool calls. It is the default `shell` type: a composition that mounts `@deepseek-ai/dsh-terminal` without it has no sessions to open.

Enable these tools when the composition mounts a terminal backend and the model should be able to use terminal state across calls — stepping a debugger, exploring in a REPL, or returning to a shell after interrupting a foreground command. The guidance section steers the model toward the one-shot bash, read, write, and edit tools for bounded operations.

## 使用本包
+`terminal_open` 默认使用 Session 的当前工作目录,并以该目录解析相对 `cwd` 覆盖值。Session 切换目录后,已打开的终端仍保留各自的目录。
+
当组合挂载了终端后端、且模型应当能跨调用使用终端状态时启用这些工具——使用调试器单步调试、在 REPL 中探索,或中断前台命令后回到 shell。指引章节会引导模型对有界操作使用单次 bash、read、write 与 edit 工具。

## Use this package
+Consumer-only tests with structural Agent stubs can use `provideWorkingDirectoryFixture(ctx, defaultDirectory?)`. It supplies directory values without validating paths, changing directories, or recording events. Tests of directory behavior use `mountAgentLoopTestDependencies(ctx, { workingDirectory: true })` and real temporary directories.

### File policy and cancellation
-The engine resolves the calling Session's standing file policy and cwd for PTC execution. The VM retains the documented helper API, but it is not a security boundary: code that reaches Node remains subject to the selected OS file policy. The program-visible environment is empty. Network access is not restricted by the file policy.
+The engine captures the calling Session's effective working directory and standing file policy separately. The PTC process and every child started by that workflow retain the captured directory when the parent later moves. The VM retains the documented helper API, but it is not a security boundary: code that reaches Node remains subject to the selected OS file policy. The program-visible environment is empty. Network access is not restricted by the file policy.
The workflow requests `timeoutMs: null` from PTC. Its initial VM slice still has `syncTimeoutMs`, and a caller's abort signal still applies, including an enclosing tool deadline. Cancellation immediately aborts the PTC process and pending or active subagents. The caller must dispose every run and await child cleanup; there is no separate workflow cleanup timer.

+引擎分别捕获调用 Session 的有效工作目录与常设文件策略。父级之后切换目录时,PTC 进程及该工作流随后启动的每个子级都保留捕获的目录。VM 保留文档说明的辅助 API,但它不是安全边界:触达 Node 的代码仍受所选 OS 文件策略约束。程序可见的环境为空。文件策略不限制网络访问。
工作流向 PTC 请求 `timeoutMs: null`。最初的 VM 片段仍受 `syncTimeoutMs` 限制,调用方的中止信号仍然生效,包括外层工具的截止。取消立即中止 PTC 进程及待启动或活跃的 subagent。调用方必须释放每次运行并等待子 agent 清理;不另设工作流清理定时器。

The selected home stores profiles, plugins, and every profile-owned durable resource. The full `sdk` profile uses its credentials, settings, and session stores; `sdk-minimal` uses only its JSONL session store. Use a fresh home when those resources must be isolated, and a fresh session id for independent work. Reusing both a harness and session id continues the durable conversation and session-owned resources.

Both create an unknown Session without running a model turn. Relative paths use that Session's current directory. Origin metadata, permissions, and existing processes remain unchanged. The low-level client provides the same methods with a leading `session_id` argument.

After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it.

Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.

create_goal may infer goal intent from a direct human request in any language. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.

create_goal may infer goal intent from a direct human request in any language. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.

The DeepSeek Harness implementation checkout is at {{sourceRoot}}. The checkout location and current working directory are separate values and may differ; never infer the working directory from this path. Use pwd to determine the current working directory. Use this checkout only to inspect or extend DSH itself.
You are interacting with the user through the DeepSeek Harness Web GUI at {{webUrl}}. When the user refers to "this page", "this GUI", or "this app" without naming another target, they mean this GUI. The browser provides no implicit DOM, route, or screenshot context. The client-plugin HMR receiver is active, but client-plugin changes reload without a refresh only while `pnpm run dev:web` is also running from this same checkout to rebuild their bundles; verify that watcher before promising automatic updates. Every other change — the apps/web shell and plain packages — requires rebuilding the affected Web artifacts and verifying this existing URL after a page refresh. Starting another server does not update this GUI. The apps/web Vite entry builds the shell but is not a standalone application because only dsh web injects window.__DSH_BOOT__. Do not start a replacement server unless the user asks; if one is needed, use a managed background job and verify its exact URL.
