Raw Blame History

工具 Schema 目录

English | 中文

已发布插件向 ctx.tools 提供的所有面向模型的工具：模型通过系统提示词组装获得的 name、description 和 JSON Schema parameters。本目录是子系统页面（类型及每页生成的 cordis-surface 接线区域）的补充；本页列出的是向 agent（智能体）提供的工具。

英文源文件由系统生成，并通过 pnpm run verify-tool-catalog（doc-sync（文档同步门禁）的一部分）验证新鲜度；本中文文件作为经评审对侧通过双语配对维护。与 Cordis 目录（纯源码 AST 处理）不同，英文生成器会在真实上下文中启动每个工具插件并读取 ctx.tools.schemas()，因为工具 schema 无法通过静态分析完全确定，例如运行时展开的枚举、拼接的描述、由配置决定的名称以及使用原始 JSON Schema 的 MCP 工具。完整性守卫会 glob 匹配 packages/*/tool-*；如果生成器的启动 manifest（元数据清单）遗漏任何包，检查就会失败，因此新工具不会在无人察觉的情况下缺少文档。

范围：packages/*/tool-* 下已发布的产品工具，每个工具均使用其默认配置启动；但如果某个 Config 字段是必填项且没有默认值，生成器就必须作出选择，对应包的说明会记录本页展示的是哪个分支。注册的工具名称可以是加载时配置，例如 tool-subagent 的 toolName，因此部署可能以不同名称或额外名称提供某个包；如果存在随产品发布的别名，对应包的说明会予以记录。examples/ 中的演示工具（例如 echo）不在范围内，这与 Cordis 目录仅涵盖包的范围一致。

工具包映射

下表将模型可见的工具名称与其背后的插件包和服务 seam 对应起来。各包章节随后给出确切的 JSON Schema。

工具包 模型可见名称 依赖 写入／影响 随产品发布的别名 部署说明
@deepseek-ai/dsh-plugin-manager plugin_manager ctx.tools, ctx.pluginManager, ctx.sandboxPolicy tool/call, tool/result, user/message - -

@deepseek-ai/dsh-mcp-resources list_mcp_resource_templates, list_mcp_resources, read_mcp_resource ctx.tools, ctx.mcpResources tool/call, tool/result - -
@deepseek-ai/dsh-experimental-browser-use-stagehand-native stagehand_act、stagehand_extract、stagehand_navigate、stagehand_observe、stagehand_screenshot、stagehand_tabs ctx.browserUse、ctx.agents、ctx.tools、ctx.systemPrompt tool/call、tool/result - -
@deepseek-ai/dsh-action-cards propose_action ctx.tools、ctx.agents、ctx.sessionProjections、ctx.remoteAccess tool/call、tool/result、plugin:action-cards/decision、user/message - 只向加载过已注册卡片种类 Skill 的 Agent 声明；各种类的包注册自己的动作，个性化推荐 Bundle 提供随产品发布的种类。
@deepseek-ai/dsh-tool-ask-user ask_user_question ctx.tools、ctx.userQuestions tool/call、tool/result after an answer or timeout、late user/message - ask_user_question 默认保持原有阻塞行为；设置 mode: timed 后才启用前台超时与 pending 结果，同时问题仍可回答；timed 模式内 timeout: -1 让本次调用无限期阻塞。
@deepseek-ai/dsh-tool-executor-ptc run_code ctx.workingDirectory (Agent executions)、ctx.tools、ctx.ptcRuntime、ctx.systemPrompt tool/call、one tool/ptc-dispatch-start + tool/ptc-dispatch pair per bridged sub-call、tool/result - PTC 执行器只向模型公开 run_code，并在运行时语言生成的 SDK 中声明其他可见能力。程序绑定按提交顺序进入共享的受守卫工具流水线；并行安全的函数体最多重叠 maxParallelSubCalls 个，嵌套结果保持与外层程序关联。
@deepseek-ai/dsh-plan-mode exit_plan_mode ctx.tools、ctx.systemPrompt、ctx.agents、ctx.userQuestions (execution time, opportunistic) tool/call、plan/mode inactive on an approved review、tool/result - 规划未激活时，exit_plan_mode 仍保留在面向模型的 schema 中，这样状态转换不会在规划策略变更之外额外造成工具目录变动。其执行路径会拒绝规划模式之外的调用；在规划模式下，它通过用户交互 seam 提交计划（批准／根据反馈继续规划），批准后会在步骤边界记录规划模式已停用。
@deepseek-ai/dsh-tool-bash bash ctx.workingDirectory、ctx.tools、ctx.shell、ctx.systemPrompt、ctx.shellEnv、ctx.jobs for run_in_background and the job-backed foreground path tool/call、tool/result - bash 工具是 bash 执行器 seam 面向模型的消费方。组合中有 job 注册表时，每次调用一启动就注册到通用 ctx.jobs 运行时，并通过 job_* 工具（来自 @deepseek-ai/dsh-tool-jobs）收集／停止；没有注册表或 enableRunInBackground: false 时，工具注册不带 run_in_background 参数的纯前台 schema。
@deepseek-ai/dsh-tool-present present ctx.workingDirectory、ctx.tools, ctx.fs, ctx.agents tool/call, deliverables/presented 在成功的最终结果之后, tool/result - 交付归调用方 Session 所有；Web ui-deliverables 提供源文件打开与卡片。
@deepseek-ai/dsh-tool-pwsh pwsh ctx.workingDirectory、ctx.tools、ctx.shell、ctx.systemPrompt、ctx.shellEnv、ctx.jobs for run_in_background and the job-backed foreground path tool/call、tool/result - pwsh 工具是 Windows 组合中 bash 执行器 seam 的 PowerShell 方言消费方（由 @deepseek-ai/dsh-pwsh-local 等 PowerShell 执行器为 ctx.shell 提供后端）；除沙箱接口外，它逐项对应 bash 工具调用。使用 run_in_background 的运行会注册到通用 ctx.jobs 运行时，并通过 job_* 工具收集／停止；托管的 DSH_* 环境来自 @deepseek-ai/dsh-shell-env。每次调用都在新进程中运行，不使用持久 PTY 会话。路径采用原生 C:\... 形式，变量采用 $env:NAME。
@deepseek-ai/dsh-tool-cordis cordis_inspect_list, cordis_inspect_query ctx.tools, ctx.cordisInspect tool/call, tool/result - 创造模式提供两个只读运行时检查工具。Cordis host runner 提供检查注册表；Client 查询需要已连接页面。持久化变更编写为组合包，再通过 plugin_manager 安装。
@deepseek-ai/dsh-tool-bash-persistent bash ctx.workingDirectory、ctx.tools、ctx.terminals、an owning Agent at execution time tool/call、PTY shell state、tool/result - 一个按所有者隔离的持久 bash 工具；部署组合提供 PTY 后端，并可覆盖面向模型的环境描述。
@deepseek-ai/dsh-tool-pwsh-persistent pwsh ctx.workingDirectory、ctx.tools、ctx.terminals、an owning Agent at execution time tool/call、PTY shell state、tool/result - 一个按所有者隔离的持久 pwsh 工具，持久 bash 工具的 Windows 对应物；部署组合提供 pwsh 方言的 PTY 后端，并可覆盖面向模型的环境描述。
@deepseek-ai/dsh-tool-str-replace-editor str_replace_editor ctx.tools、ctx.fs tool/call、fs/observed after view presence/absence, edit absence, or successful mutation、tool/result - 基于文件系统 seam 的独立查看／创建／唯一字面量替换／按行插入工具；可与任何 shell 或终端接口组合。
@deepseek-ai/dsh-tool-fs edit、read、read_image、write ctx.workingDirectory、ctx.tools、ctx.fs、ctx.systemPrompt、ctx.attachments (image-tool registration)、ctx.llm + an image-capable route (image-tool execution) tool/call、fs/write-intent or fs/edit-intent for mutations、fs/observed after read presence/absence or successful file operation、durable attachment (read_image)、tool/result - 先读后写／编辑策略由 @deepseek-ai/dsh-fs-observation-policy 添加；它是一个 fs/* 事件门禁插件，不会改变 schema。加载这些工具的部署按预期也应加载该插件。没有 ctx.attachments 时图片工具不会注册；其 schema 与路由无关，执行时除非确切路由的模型声明图片输入，否则拒绝。
@deepseek-ai/dsh-tool-fs-search glob、grep ctx.workingDirectory、ctx.tools、ctx.subprocess、ctx.systemPrompt tool/call、tool/result - glob 和 grep 是无条件可用的发现工具，通过 ctx.subprocess spawn 随包提供的 ripgrep 二进制文件（@vscode/ripgrep），并作为普通前台调用运行，绝不作为后台任务；无需在宿主机安装 rg，也不经过 shell 层。本目录使用 sampleOverCapGlobResults: true；部署必须显式选择该行为。结果超过上限时，会通过可选的 ctx.spillStore 后端保存完整的格式化列表；在共置部署中，如果后端公开本地路径，返回的定位信息可供后续读取／搜索。
@deepseek-ai/dsh-tool-terminal terminal_close、terminal_list、terminal_open、terminal_read、terminal_send、terminal_signal ctx.workingDirectory、ctx.tools、ctx.terminals、ctx.systemPrompt、ctx.jobs at call time for run_in_background tool/call、tool/result - 这 6 个终端工具需要选择启用，用于补充一次性 bash／文件系统工具。terminal_send(run_in_background: true) 会注册到 ctx.jobs；schema 不包含 TUI、具名按键序列、BEL、调整尺寸、自动启动和跨 agent 共享。
@deepseek-ai/dsh-tool-goal create_goal、get_goal、update_goal ctx.tools、ctx.agents、ctx.goals、ctx.systemPrompt、a calling Agent in an authorized open turn tool/call、goal/change for mutations、tool/result - create、edit、pause 和 resume 要求直接来自人类的根权限；complete 和 blocked 也接受确切的当前 Goal Round。blocked 的默认下限是 3 个获准的 Round。
@deepseek-ai/dsh-tool-schedule schedule_create、schedule_edit、schedule_list、schedule_view ctx.tools、ctx.schedule、ctx.systemPrompt tool/call、Schedule storage domain 创建、更新或删除、tool/result - preset 或 Agent scope 挂载本包，并决定哪些 Agent 获得工具。管理工具按 id 跨会话读写 Host 的任务。任务保存 RFC 5545 重复规则，执行位置可选已有会话、首次创建后复用的会话或每次运行新建的会话。委派子 Agent 不能调用这些工具。
@deepseek-ai/dsh-tool-lsp lsp ctx.workingDirectory、ctx.tools、ctx.lsp、ctx.systemPrompt tool/call、tool/result - lsp 工具将提供方选择和语言服务器子进程置于 ctx.lsp 之后，因此其模型可见 schema 在更换提供方时保持稳定。运行时要求已注册提供方，例如 @deepseek-ai/dsh-lsp-stdio；如果没有提供方，查询会返回结构化 LSP_UNAVAILABLE 错误，而不会改变 schema。
@deepseek-ai/dsh-tool-ralph ralph ctx.tools、ctx.workflowEngine、ctx.subagents、ctx.systemPrompt、a calling Agent (exec.agent parents every fresh round) tool/call、tool/result、workflow and child session events during execution - 固定的前台工作流会在每个 Round 启动一个全新的结构化子级；模型只能选择不可变目标和可选的 Round 上限。
@deepseek-ai/dsh-tool-skill skill ctx.workingDirectory、ctx.tools、ctx.agents、ctx.skills tool/call、tool/result、user/message replacement catalogs via agent.inject() - -
@deepseek-ai/dsh-tool-session-query session_event_read、session_event_search、session_event_trace、session_search、session_trace ctx.tools、ctx.systemPrompt、ctx.sessionQuery、a calling Agent for workspace authority tool/call、tool/result - 这 5 个只读工具会隐藏提供方游标，并根据不可变的调用 agent 会话为每个结果授权。该包需要选择启用；需要强制截止时间或限制行内输出的组合还会挂载通用超时或 spill 策略。
@deepseek-ai/dsh-experimental-tool-subagent-oar subagent_oar ctx.tools, ctx.subagents tool/call, tool/result, parent subagent catalog and completion notices - subagent_oar 工具在为外部提供方配置的别名之间选择。本目录展示 Codex 和 Claude Code 别名；每个部署自行选择提供方。原生模型和权限设置由所选提供方的配置决定。
@deepseek-ai/dsh-tool-subagent list_subagent_models、subagent ctx.tools、ctx.subagents、ctx.systemPrompt、ctx.sessionProjections、用于模型发现和所选路由校验的 ctx.llm tool/call、tool/result、child session events through the chosen provider subagent、subagent_fork 加载时的 toolName 选择委派名称（默认为 subagent）；modelSelection 增加可选路由字段。modelDiscovery 默认关闭，每个作用域由一个实例注册共享发现工具。Web 与 Desktop preset 启用 spawn 发现和路由字段，并为 subagent_fork 保持路由字段关闭。Host 设置服务为每个新顶层 Session 记录授权；子 Session 继承该授权。没有已记录策略时，发现和显式选择只允许当前父级路由。每次委派都会立即返回子代理 id；本地子代理接受后续消息，外部后端自动汇报单次执行结果。
@deepseek-ai/dsh-tool-subagent-control interrupt_agent、list_agents、send_message、wait_agent ctx.tools、ctx.subagents、ctx.agents tool/call、tool/result、child session events through ctx.subagents - 共享控制工具发现并联系 subagent 树中的 Agent，中断有权控制的后代，并等待调用者收件箱中的输入。绑定提供方的 tool-subagent 实例提供委派工具。
@deepseek-ai/dsh-tool-jobs job_kill、job_list、job_output ctx.tools、ctx.jobs、ctx.systemPrompt tool/call、tool/result、user/message via agent.inject() for background completion notices - 与任务种类无关的后台任务控制器：后台 bash 命令与 PTY 发送 都通过相同的 3 个工具读取、列出和终止。加载该插件会挂接控制器，从而启用生产方的 ctx.jobs.start()。
@deepseek-ai/dsh-experimental-tool-agent-team team_task_create, team_task_get, team_task_list, team_task_update ctx.tools, ctx.systemPrompt, ctx.agentTeams, ctx.subagents, an exact live Team member Agent tool/call, team/task, tool/result - 四个任务板工具共享 subagent 树的根 Session。可选 Agent Teams profile 在标准子代理委派和控制工具之外增加任务板指导，以及从 subagent 根派生的必需 Team 身份。
@deepseek-ai/dsh-tool-todo todo_write ctx.tools、owning Agent session tool/call、todo/write、tool/result - todo_write 是会话所有的状态；UI 将最新的 todo/write 事件渲染为检查清单。allowParallelInProgress 是没有默认值的必填项，因此本目录明确选择 true，对应描述允许同时存在多个 in_progress 项。选择 false 的部署会获得同一工具，但描述会要求只能有 1 个活动任务。
@deepseek-ai/dsh-tool-working-directory working_directory ctx.tools, ctx.workingDirectory tool/call, working-directory/change, user context for directory changes, tool/result - 读取或改变调用方 Session 的目录。已有 shell 和进程保留自己的目录；原始元数据和权限根目录保持不变。
@deepseek-ai/dsh-experimental-tool-worktree create_worktree ctx.tools, ctx.worktrees, a calling Agent tool/call, Git branch and checkout, working-directory/change, tool/result - 仅通过显式实验组合加载。在现有写权限下从固定的本地提交创建新分支与检出目录，再改变 Session 工作目录。离开时保留分支与检出目录。
@deepseek-ai/dsh-tool-workflow workflow ctx.tools、ctx.workflowEngine、ctx.systemPrompt、a calling Agent (exec.agent parents the script children) tool/call、tool/result - -
@deepseek-ai/dsh-tool-workspace-dependencies load_workspace_dependencies ctx.tools tool/call, tool/result - -
@deepseek-ai/dsh-tool-web web_fetch、web_search ctx.tools、ctx.web、ctx.systemPrompt tool/call、tool/result - web_search 和 web_fetch 将提供方选择置于 ctx.web 之后，使模型可见 schema 在更换后端时保持稳定。

run_code

针对可用工具执行 TypeScript 程序。接受两个必填参数：code，异步函数的函数体（仅限可擦除语法，支持顶层 await 和 return）；以及 description，简要说明程序做什么。请按系统提示词中的声明，以 await tools.name(args) 调用工具。只有打印或返回的内容构成程序输出，请筛选这些内容。含图片的子工具结果会在运行结束后附加。程序是异步 TypeScript 函数的函数体，只接受可擦除语法，不支持 enum 或 namespace。类型标注只作提示。支持顶层 await 和 return。使用 console.log(...) 或返回无损 JSON 值来输出。只有打印值和返回值成为程序输出。每次调用在新的 Node 进程中运行，可通过 await import(...) 使用 Node API。相对路径以传入的工作目录为准；process.env 初始为空。直接文件系统访问遵循本次执行的沙箱策略。每个程序从 Session 的当前目录启动，运行中保留初始目录。沙箱提权只为本次完整程序执行授权。嵌套工具保留自身策略与审批。只有在获得拒绝证据后才请求更宽访问。先前效果可能已经发生，请在显式重试前检查。程序不会自动重放。

pwsh

执行 PowerShell 命令（pwsh -Command）并返回 stdout/stderr。每次调用都在新的 pwsh 进程中运行；请传入 workdir，不要使用 cd。路径采用 Windows 原生形式（C:\...）；使用 $env:NAME 读取环境变量。托管的 $env:DSH_* 变量公开当前 harness 环境信息。较长的输出会截断，只保留尾部；如可用，完整输出会保存到文件并报告其路径。在 Windows 上，被强制终止的命令会以 [exit code: 1] 结算且不带信号标记，请将其视为中断，而不是命令失败。请在参数中先提供 description，再提供 command。在任何删除或移动之前，请确认解析后的绝对目标路径正是预期路径；绝不要对未经检查的计算路径执行此类操作。不要给 $HOME 等自动变量赋值；变量名不区分大小写，因此 $home 就是同一个只读变量。命令可能在文件沙箱中运行；被阻止的文件操作报告为 [sandbox: file access denied under <mode> mode]，这是策略拒绝：请勿换一种方式重试。

str_replace_editor

用于查看、创建和编辑文件的自定义编辑工具：

  • 状态会在命令调用以及与用户的讨论之间持久保留
  • 如果 path 是文件，view 会显示应用 cat -n 后的结果。如果 path 是目录，view 会列出最多向下 2 层的非隐藏文件和目录
  • 如果指定的 create 命令目标 path 已作为文件存在，则不能使用该命令
  • 如果 command 产生较长输出，输出会被截断并标记为 <response clipped>
  • 当前命令不使用某个参数时，值为 null 的占位参数视为未提供。必填参数仍须提供值；删除匹配内容时应省略 str_replace.new_str，而不是将其设为 null

使用 str_replace 命令时请注意：

  • old_str 参数应与原文件中一行或多行连续内容完全匹配。请留意空白字符！
  • 如果 old_str 参数在文件中不唯一，则不会执行替换。请确保在 old_str 中包含足够的上下文，使其唯一
  • new_str 参数应包含用于替换 old_str 的已编辑行

glob 和 grep 是无条件可用的发现工具，通过 ctx.subprocess spawn 随包提供的 ripgrep 二进制文件（@vscode/ripgrep），并作为普通前台调用运行，绝不作为后台任务；无需在宿主机安装 rg，也不经过 shell 层。本目录使用 sampleOverCapGlobResults: true；部署必须显式选择该行为。结果超过上限时，会通过可选的 ctx.spillStore 后端保存完整的格式化列表；在共置部署中，如果后端公开本地路径，返回的定位信息可供后续读取／搜索。

schedule_create

创建定时任务。rrule 的每次触发都会将 prompt 作为用户的定时消息投递到目标会话。结果包含任务 id 和下一次触发时间：scheduledAt 为 UTC 时间，scheduledAtLocal 为 rrule 所在时区的时间。停机后只补发最近一次错过的触发。崩溃后可能重复投递。

A TZID rule keeps local clock time across daylight-saving changes; generated nonexistent local times are skipped, and repeated ones occur once, at the earlier instant. DTSTART may be in the past; delivery starts with the first occurrence after creation. A one-time delivery is RRULE:FREQ=DAILY;COUNT=1. No SECONDLY; BYSECOND takes one value.

subagent_oar

将上下文完整的任务委派给已配置的外部 agent。每次调用选择一个运行时。subagent 在独立上下文中工作，无法看到当前对话。工具返回子级 id，后续完成通知包含其最终回答。subagent 不接受后续消息。并发启动相互独立的任务，并在其运行期间继续其他有用工作。只剩等待结果时结束当前轮次，不要轮询。

subagent

将一项自包含任务委派给 subagent（在自身上下文中工作的独立 agent），用它卸载聚焦且独立的工作，例如研究、限定范围的实现或分析，以免消耗当前对话的上下文。subagent 会返回结果，但不会返回中间步骤。此工具启动独立管理的 subagent 并立即返回其 id。如果它结束时你仍在线，运行时会自动递送其完成通知。通知包含最终回答，除非子任务在结束前刚给你发过消息。你可以使用 send_message 在运行时引导它，或在结束后继续对话。

加载时的 toolName 选择委派名称（默认为 subagent）；modelSelection 增加可选路由字段。modelDiscovery 默认关闭，每个作用域由一个实例注册共享发现工具。Web 与 Desktop preset 启用 spawn 发现和路由字段，并为 subagent_fork 保持路由字段关闭。Host 设置服务为每个新顶层 Session 记录授权；子 Session 继承该授权。没有已记录策略时，发现和显式选择只允许当前父级路由。每次委派都会立即返回子代理 id；本地子代理接受后续消息，外部后端自动汇报单次执行结果。

interrupt_agent

根据 agent id 请求取消后台 agent 的当前轮次。目标可以是你的直接子级，也可以是在你下方创建的更深层 agent。对于本地 agent，只有当前轮次会停止：已经排队发给该 agent 的消息会一直搁置到后续的 send_message；它启动的 agent 会继续运行；该 agent 本身仍可接受后续操作。外部执行会永久停止，无法接收后续消息。停止请求被接受后，此调用立即返回，因此目标可能还会短暂运行；中断一个已经完成的 agent 是可接受的空操作。

@deepseek-ai/dsh-tool-workflow

workflow

运行用于大规模编排 subagent 的 JavaScript 工作流脚本。当工作会分散到许多相互独立的部分时，请使用此工具，例如审查大量文件、执行迁移、开展多角度研究或对发现进行对抗式验证；此时应将编排写成脚本，而不是逐轮委派。

脚本函数体提供以下钩子：

  • agent(prompt, opts?): Promise<any>：运行一个 subagent 直至完成。不提供 opts.schema 时，解析为子级最终文本；提供 opts.schema 时，它必须是以对象为根、且只能使用 type/properties/required/additionalProperties/items/enum/const/oneOf 的 JSON Schema，此时解析为通过校验的对象。子级失败时解析为 null，可使用 .filter(Boolean) 过滤。其他选项包括 label（显示名称）、phase（进度组），以及相互独立的 provider／model LLM（大语言模型）目标覆盖项。
  • pipeline(items, ...stages): Promise<any[]>：让每个条目分别经过各阶段，阶段之间没有屏障；多阶段工作优先使用它。每个阶段接收 (prev, item, index)。阶段异常会将该条目变为 null，并跳过它的剩余阶段。
  • parallel(thunks): Promise<any[]>：并发运行零参数函数并等待全部完成。它会形成屏障，仅当某个阶段确实需要汇总全部先前结果时使用。抛出异常的 thunk 解析为 null。
  • phase(title)：开始一个进度阶段；log(message)：说明进度；args：工具调用的 args 输入，原样提供。

如果误用钩子（参数错误、未知选项、不受支持的 schema、触发上限），整个脚本会终止，而不会产生 null。脚本没有文件系统、网络、定时器或 Node.js API；具体工作由 agent 完成。
