# @deepseek-ai/dsh-subagent-claude-code
|
||
|
||
[English](README.md) | 中文
|
||
|
||
本包(package)注册固定的 `claude-code` subagent 提供方。每次接受运行请求后,它都会在发起委托的会话工作区中调用官方 Claude Agent SDK,通过共享子进程服务解析原生 `claude` 可执行文件,提交一个自包含的文本任务,并通过共享的 [`dsh-subagent`](../subagent/README.md) 结果约定仅返回最终答案。
|
||
|
||
## 启动与所有权
|
||
|
||
`start(request)` 只接受非空的文本块序列,并根据父会话确定子级 cwd。它会创建一个私有 `AbortController`,调用官方 SDK 的 `query()`,并仅在 SDK 的 `spawnClaudeCodeProcess` 钩子已经提供由 [`dsh-subprocess`](../../subprocess/subprocess/README.md) 管理的活动 CLI 句柄后发布此次运行。若在发布前发生失败或取消,它会关闭 query、终止所有已取得的进程树并等待其退出,然后拒绝 `start()` 调用。
|
||
|
||
SDK 接收由文本块原样拼接成的任务。提供方会完整迭代 SDK 消息流,而且只接受满足以下条件的 `result` 消息:其 `subtype: "success"`、`is_error: false` 且 `result` 非空白,之后迭代器还须正常结束。所有 SDK 错误子类型、标记为错误的成功消息、缺失答案、迭代器失败、协议失败或进程失败都映射为 `error`;该提供方不会产生 `max-tokens` 或 `refusal`。
|
||
|
||
本地取消会在结果竞态中胜出并映射为 `aborted`。`dispose()`(资源释放)具有幂等性:它会中止此次运行、请求 SDK query 关闭、调用共享的进程树逐级终止机制,并等待整棵进程树退出。SDK 的优雅关闭只表达协议意图;进程是否完全停稳仍以子进程句柄为准。结果失败与独立的清理失败仍彼此分离。
|
||
|
||
## 原生设置与交互
|
||
|
||
提供方故意省略 SDK 的 `settingSources` 选项。因此,官方 SDK 会相对于父会话 cwd 读取宿主机常规的用户、项目和本地 Claude 设置,包括原生账户状态与产品配置。提供方既不复制也不过滤这些文件,也不会创建或修改登录状态。
|
||
|
||
每次 query 都设置 `persistSession: false` 并禁用 `AskUserQuestion`。提供方不设置 `canUseTool`、elicitation 或对话回调,因此无人值守交互会经 SDK 失败,而不会等待本提供方不负责的用户界面。
|
||
|
||
## 能力与上下文
|
||
|
||
本提供方不声明任何可选的启动时能力,并报告 `inheritsParentContext: false`。Claude Code 会接收独立文本任务和父会话 cwd,但不会接收父会话的对话、角色设定、工具筛选器、深度策略或结构化输出约定。每次运行都拥有独立的 SDK query、取消控制器、CLI 进程和不持久化的产品会话。
|
||
|
||
## 配置
|
||
|
||
| 配置键 | 默认值 | 含义 |
|
||
|---|---|---|
|
||
| `env` | `{}` | 显式指定的 SDK/CLI 环境,叠加在由共享机制清除凭证后的父环境之上。 |
|
||
| `disposeGraceMs` | `3000` | 共享进程树责任方各终止层级之间的宽限期,单位为毫秒且须为正有限值,并不得大于仓库共享的 [`MAX_TIMER_DELAY_MS`](../../util/timeout/README.md);随后资源释放会等待整棵进程树退出。 |
|
||
|
||
生产环境从子进程执行世界清除凭证后的 `PATH` 解析 `claude`,再应用显式 `env` 条目,并把所得路径作为 `pathToClaudeCodeExecutable` 交给 SDK。在 Windows 上,解析到的 `.cmd` 或 `.bat` 路径会作为带引号、仅供本次 spawn 使用的环境值交给 `cmd.exe /v:off` 展开一次,因此合法路径中的元字符仍只是数据。锁定版本的 SDK 随后把固定命令行选项放在 cmd 的命令尾部;这些选项不含 cmd 元字符,也并不是普通的 Windows argv。原生设置与身份验证继续是权威来源。本插件不安装另一份 CLI、不选择模型、不创建产品主目录、不执行登录,也不探测账户。具有凭证特征的环境变量会在显式 `env` 覆盖生效前被清除,因此供子进程使用的 API 密钥或 token 必须在该配置中显式提供。除非被覆盖,`ANTHROPIC_BASE_URL` 等非凭证端点变量以及 `PATH` 和 `HOME` 等普通环境变量仍会被继承。
|
||
|
||
`dsh-base` 宿主平面会挂载本提供方,`code`、`cordis` 与 `standard` Agent Preset 均携带已启用的 `subagent_claude_code` 工具行;`economy` preset 保留 `disabled: true`,因为经济模式的组装不应默认动用外部付费 agent。加载提供方本身不会在工具调用前启动 Claude 进程。其 `one-shot` 策略会让省略 `run_in_background` 或传入 `false` 的调用继续在前台等待,而显式传入 `true` 会返回由父 agent 拥有的 Job ID,供 `job_output` 或 `job_kill` 使用。base host(基础宿主)与完整 preset 已提供通用作业注册表和控制工具。
|
||
|
||
下列独立组装展示完整的显式能力。基于 `@deepseek-ai/dsh-base` 的 Profile 保留已有 Job 行,只新增产品提供方行并启用 preset 工具行,禁止重复挂载 Job 服务。

||

||

|
||

|
||

toolName: subagent_claude_code
|

backgroundMode: one-shot
|
||

|
||
```
|
||
|
||
## 产品兼容性与证据
|
||
|
||
运行时依赖精确锁定为 `@anthropic-ai/claude-agent-sdk@0.3.220`。生产运行使用原生 `claude` 安装。无密钥真实产品测试使用由 SDK 分发的 Claude Code 2.1.220 CLI 作为确定性 fixture(测试前置数据),并通过同一套原生可执行文件解析路径与 Windows batch shim 路径运行;这项测试不声称兼容每个独立安装的版本。Loader 组合证明两个产品包能够共存且不会启动任一产品。
|
||
|
||
限定于项目所有者身份的分发授权涵盖官方 SDK 及每个 SDK 版本声明的官方 CLI/平台载荷。[`THIRD_PARTY_NOTICES.md`](../../../THIRD_PARTY_NOTICES.md) 会披露当前可选载荷闭包,但不会认定其中声明的条款属于宽松许可;其他无关的非宽松运行时依赖仍会使第三方声明门禁失败。
|
||
|
||
## 模型体验
|
||
|
||
### 子级请求
|
||
|
||
#### 模型看到的内容
|
||
|
||
Claude Code 子级会在一个全新的 SDK query 中接收独立文本任务。它的工作区是父会话 cwd;其模型、系统指令、工具、权限和身份验证来自宿主机原生 Claude 设置与产品安装。
|
||
|
||
#### 对 token 的影响
|
||
|
||
子级需为独立的 Claude Code 上下文和 query 承担 token 开销。子级 token 不会进入父级上下文。
|
||
|
||
#### 对 KV Cache 的影响
|
||
|
||
这与父请求缓存相互独立。能否复用只取决于 Claude Code 自身的模型、指令、工具、原生设置和全新 query。
|
||
|
||
### 父级调度与结果(间接)
|
||
|
||
#### 模型看到的内容
|
||
|
||
通过 `dsh-tool-subagent`,前台调用会让父级模型看到符合严格成功条件的 Claude Code 最终答案,或者在结果未完成时看到消费方给出的原样错误。后台调用会先返回 Job id;随后通用作业控制面会送达完成通知,通过 `job_output` 公开最终答案与状态,并允许 `job_kill` 请求取消。Claude Code 的推理、工具活动、中间消息、stderr、工作区差异、用量信息和产品标识符均不会复制到父会话。
|
||
|
||
#### 对 token 的影响
|
||
|
||
前台输入会增加工具结果中保留的最终答案或错误内容。后台输入还会包含启动确认、完成通知,以及 `job_output`、`job_kill` 或后续状态结果;子任务 token 仍不会进入父级上下文。本提供方自身不添加父级工具 schema。
|
||
|
||
#### 对 KV Cache 的影响
|
||
|
||
仅追加:前台会在可复用的父请求前缀后增加一个结果,后台则会继续追加 Job 启动确认、通知以及后续控制或收集结果。后台调度可能增加一个由通知唤醒的轮次,但这些消息都不会改写更早的前缀。
|
||
|
||
## 已知限制与后续工作
|
||
|
||
- **每次运行均新建一个 query 和一个进程**:不支持续接、恢复、池化、进度流或产品会话持久化。
|
||
- **宿主设置有意保持权威**:项目和用户设置可以改变模型、工具与行为;本提供方不提供经过筛选或与宿主环境隔离的生产模式。
|
||
- **产品安装与账户状态仍由原生机制管理**:`claude` 缺失或不兼容、配置错误或身份验证失败都会呈现为启动错误或运行错误;本插件不提供安装程序或登录流程。
|
||
- **SDK 平台 CLI 仍在安装闭包内**:生产环境会忽略它,改用宿主提供的 `claude`,但当前 SDK 的可选依赖仍会安装,并提供无密钥兼容性 fixture。移除该载荷属于独立的产品安装闭包后续项。
|
||
- **没有人工交互路径**:`AskUserQuestion` 被禁用,其他交互回调也不存在,因此需要新审批或输入的任务会失败而不会挂起。
|
||
- **产品载荷仅包含最终文本**:推理、中间消息、工具通信、用量信息、stderr 和工作区差异仍只保留在产品内部;通用 Job id、通知与状态来自共享作业运行时。
|
||
- **没有可选的共享能力**:对于本提供方,共享服务会拒绝输出 schema、子任务角色设定、工具筛选和 harness 深度强制约束。
|
||
- **没有按实际经过时间触发的超时或副作用回滚**:长时间运行的工作由调用方取消,且取消前已更改的文件或外部系统不会恢复原状。
