[`tool-bash`](../packages/bash/tool-bash)、[`tool-pwsh`](../packages/bash/tool-pwsh)、[`hooks-claude`](../packages/hooks/hooks-claude)、[`hooks-codex`](../packages/hooks/hooks-codex) | - | 面向模型的 shell 工具和钩子桥接消费此 seam；沙箱、远程或 PowerShell 执行器可以替换 bash-local，而无需改动这些消费方。 | | `ctx.bashEnv` | `core` | [`bash-env`](../packages/bash/bash-env) | - | [`tool-bash`](../packages/bash/tool-bash)、[`tool-pwsh`](../packages/bash/tool-pwsh) | - | 插件声明限定于 effect 作用域的 DSH_* 事实；每个 shell 工具在每次执行时收集一份可信快照，其执行器据此重建命名空间。 | | `ctx.pty` | `seam` | [`pty`](../packages/pty/pty) | [`pty-local`](../packages/pty/pty-local) | [`tool-pty`](../packages/pty/tool-pty) | - | 注册表负责精确到 Agent 的会话身份和清理；后端负责终端机制，tool-pty 则提供限定于所有者作用域的模型接口。 | | `ctx.sandbox` | `seam` | [`sandbox`](../packages/sandbox/sandbox) | [`sandbox-local`](../packages/sandbox/sandbox-local) | [`bash-sandbox`](../packages/bash/bash-sandbox)、[`pty-local`](../packages/pty/pty-local) | - | 消费方交出即将执行 spawn 的确切 argv；与宿主共享文件系统和内核的后端按每次调用的策略包装该 argv，并报告强制执行情况。 | | `ctx.sandboxPolicy` | `core` | [`sandbox-policy`](../packages/sandbox/sandbox-policy) | - | [`bash-sandbox`](../packages/bash/bash-sandbox)、[`fs-sandbox`](../packages/fs/fs-sandbox)、[`pty-local`](../packages/pty/pty-local) | - | 统一保存部署默认模式和工作区根目录；只有沙箱执行器和提供方读取该服务（工具层使用它同时导出的纯 `sandbox/mode` 折叠区）。两类强制执行组件都读取该服务，因此 bash 与 fs 不会限制到不同的根目录。 | | `ctx.approval` | `seam` | `approval` | [`acp`](../packages/acp/acp) | [`tools`](../packages/core/tools)、[`tool-bash`](../packages/bash/tool-bash) | - | 一次性权限决策通过 `approval/request` waterfall（瀑布式事件）分派；回答方是监听器（即 ACP 为自身 agent 提供的桥接），没有回答方时以 `unavailable` 关闭失败。 | | `ctx.permission` | `core` | [`permission`](../packages/interaction/permission) | - | - | - | 面向用户的预设表（`workspace-write`／`danger-full-access`），将沙箱模式与审批策略选项组合在一起；一次切换会写入一个 `permission/preset` 事件，并贯通到两个选项事件。 | | `ctx.codeRuntime` | `seam` | [`code-runtime`](../packages/code-runtime/code-runtime) | [`code-runtime-worker`](../packages/code-runtime/code-runtime-worker) | [`tools`](../packages/core/tools) | - | 使用 Host 提供的异步绑定运行一段由模型编写的程序；各后端采用不同的基础环境和语言（工具注册表在 Code Mode 下消费该服务）。 | | `ctx.fs` | `seam` | [`fs`](../packages/fs/fs) | [`fs-local`](../packages/fs/fs-local)、[`fs-sandbox`](../packages/fs/fs-sandbox)、[`fs-e2b`](../packages/e2b/fs-e2b) | [`tool-fs`](../packages/fs/tool-fs) | [`fs-policy`](../packages/fs/fs-policy) | tool-fs 通过 ctx.fs 执行读取／写入／编辑；fs-sandbox 按共享沙箱模式限制变更；fs-policy 通过 fs/* 事件门禁贡献基于观测状态的检查。 | | `ctx.compact` | `seam` | [`compact`](../packages/compact/compact) | [`compact-basic`](../packages/compact/compact-basic) | [`compact-basic`](../packages/compact/compact-basic) | - | 基础后端消费步骤后的压力事件和请求错误恢复事件；不存在面向模型的压缩工具。 | | `ctx.subagents` | `seam` | [`subagent`](../packages/subagent/subagent) | [`subagent-spawn`](../packages/subagent/subagent-spawn)、[`subagent-fork`](../packages/subagent/subagent-fork)、[`subagent-acp`](../packages/subagent/subagent-acp)、[`subagent-codex`](../packages/subagent/subagent-codex)、[`subagent-claude-code`](../packages/subagent/subagent-claude-code)、[`subagent-dsh-sdk`](../packages/subagent/subagent-dsh-sdk) | [`tool-subagent`](../packages/subagent/tool-subagent)、[`tool-subagent-control`](../packages/subagent/tool-subagent-control)、[`tool-ralph`](../packages/workflow/tool-ralph) | - | 提供方实现传输；该服务还负责可选的、基于 Activation 的延续编排，tool-subagent 选择一次性或可延续委派，tool-subagent-control 传递后续消息，而 tool-ralph 要求一条全新的结构化输出路由。 | | `ctx.tasks` | `seam` | [`tasks`](../packages/tasks/tasks) | [`tasks-local`](../packages/tasks/tasks-local) | [`tool-bash`](../packages/bash/tool-bash)、[`tool-pty`](../packages/pty/tool-pty)、[`tool-subagent`](../packages/subagent/tool-subagent)、[`tool-tasks`](../packages/tasks/tool-tasks) | - | 生产方（后台 bash、PTY 发送和 subagent 委派）登记正在运行的工作；tool-tasks 是面向模型的控制接口，用于读取、列出和终止这些工作；tasks-local 是进程本地注册表。 | | `ctx.web` | `seam` | [`web`](../packages/web/web) | [`web-search-exa`](../packages/web/web-search-exa)、[`web-search-perplexity`](../packages/web/web-search-perplexity)、[`web-search-deepseek`](../packages/web/web-search-deepseek)、[`web-fetch-local`](../packages/web/web-fetch-local) | [`tool-web`](../packages/web/tool-web) | - | 搜索和抓取提供方注册到同一个 ctx.web seam；tool-web 负责稳定的面向模型名称。 | | `ctx.spillStore` | `seam` | [`spill`](../packages/spill/spill) | [`spill-local`](../packages/spill/spill-local) | [`spill-policy`](../packages/spill/spill-policy) | - | 后端保存过大的工具文本，并返回面向模型的定位信息和取回提示；spill-policy 是 tools/post-execute 消费方，负责决定何时 spill。 | | `ctx.directoryPicker` | `seam` | `directory-picker` | `directory-picker-native`、`directory-picker-browse` | `apiproxy` | - | 带判别标记的交互能力：原生后端在 Host 显示设备上打开一个操作系统选择器，浏览后端为应用内浏览器提供列表与创建原语；双端后端通过其浏览器侧填充 ui-workspace 目录流程的 slot（不通过协议发布）。 | | `ctx.httpServer` | `core` | `webserver` | - | `connection`、`modules`、`hmr` | - | 普通的 node:http 载体：具名路由注册表、索引转换 tap，以及静态 dist 回退；Web 传输插件注册自己的路由。 | | `ctx.clientModuleHost` | `core` | `modules` | - | `hmr` | - | 通过增量 `dsh.client` 扫描组合 __DSH_BOOT__ 入口图，提供插件组合包，并通知重建／图变更订阅方。 | | `ctx.workflows` | `seam` | [`workflow`](../packages/workflow/workflow) | [`workflow-workerthread`](../packages/workflow/workflow-workerthread) | [`tool-workflow`](../packages/workflow/tool-workflow)、[`tool-ralph`](../packages/workflow/tool-ralph) | - | 每个上下文使用一个引擎，与 bash 相同，且没有具名提供方注册表；通用工作流与固定 Ralph 消费方启动运行，其中的 agent() 调用通过 ctx.subagents 扇出。 | 维护模式：混合模式。服务从 Cordis 声明中发现；接口、实现和消费方角色在 `scripts/gen-doc-graphs.ts` 中分类，并设有完整性守卫。
