chore: 2.4.3

模型在未通过 SearchExtraTools 发现工具的情况下直接调用 ExecuteExtraTool，
因不知道工具 schema 导致参数错误（如 libraryName: undefined）。

双重修复：
1. ExecuteTool.call() 添加服务端拦截：检查目标 deferred 工具是否已被发现
2. 更新 <available-deferred-tools> 系统提示：要求先搜索再执行

+#### 跨文件 mock 污染（process-global `mock.module`）
+
+**Bun 的 `mock.module` 是进程全局的（last-write-wins），不是 per-file 隔离的。** 一个测试文件的 `mock.module` 会污染同一进程中所有其他测试文件的 `require`/`import`。
+
+**关键事实（Bun 1.x 实测验证）：**

+- `mock.module` 在 `beforeAll` 内部调用时**不会被提升**（hoist），但仍会污染后续加载的文件。
+- `require()` 和 `import()` 共享同一模块注册表，`mock.module` 对两者都生效。
+- 一个模块一旦被某个文件的 `mock.module` 替换，同一进程中所有后续 `require`/`import` 都会返回 mock 值，即使调用方使用不同的 specifier 路径。
+
+**核心规则：不要 mock 被测模块的上层业务模块。**

+}))
+```
+

+axiosHandle.stubs.post = axiosPostMock

+
+**判断标准：** 如果目录下同时有 `launch*.test.ts`（集成测试）和 `api.test.ts`（回归测试），`launch*.test.ts` 必须 mock axios 而非源 API 模块。`api.test.ts` 需要测试真实 API 模块的 HTTP 方法/URL/错误处理逻辑，被 mock 后就无法测试。
+

+1. 单独运行可疑文件确认其通过：`bun test path/to/suspect.test.ts`
+2. 与同目录其他文件一起运行定位污染源：`bun test path/to/__tests__/`
+3. 在两个文件中各加 `console.error('[file] milestone')` 追踪实际执行顺序
+4. 检查 `mock.module` 的 specifier 是否与同目录其他测试的 `require`/`import` 路径解析到同一模块

+# ToolSearch 设计指南
+
+> 基于 feature/tool_search 分支的 4 次 commit 迭代，系统性地记录 ToolSearch 的架构、核心机制、演进历史和维护指南。
+
+## 1. 问题背景
+
+Claude Code 内置了 60+ 工具，加上用户连接的 MCP 服务器可能引入数十甚至上百个额外工具。将所有工具的完整 schema 一次性发送给模型，会产生几个严重问题：
+
+1. **Token 爆炸** — 每个工具定义（name + description + inputSchema）平均消耗数百 token，60 个工具就是数万 token 的常量开销。
+2. **Prompt Cache 失效** — 工具列表作为 prompt 的一部分参与缓存计算。任何工具的增减（如 MCP 服务器连接/断开）都会导致整段缓存失效。
+3. **模型注意力稀释** — 过多的工具定义干扰模型对核心工具的选择准确性。
+
+## 2. 解决方案概览
+
+ToolSearch 采用 **延迟加载（Deferred Loading）** 模式：
+
+- 将工具分为 **Core Tools**（始终加载）和 **Deferred Tools**（按需发现）
+- 模型通过 `SearchExtraTools` 工具搜索并发现 deferred tools
+- 通过 `ExecuteExtraTool` 工具代理执行发现的 deferred tools
+- **工具数组在会话中保持稳定**，不再动态注入已发现的 deferred tools（v3 修复的关键决策）
+
+## 3. 核心架构
+
+### 3.1 工具分类体系
+
+```
+┌─────────────────────────────────────────────────────────────┐

+│    CORE_TOOLS 白名单定义   │     isDeferredTool() 判定       │
+└───────────────────────────┴─────────────────────────────────┘
+```
+
+**Core Tools**（`src/constants/tools.ts` 中的 `CORE_TOOLS` Set）：
+
+| 类别 | 工具 |
+|------|------|
+| 文件操作 | Bash/Shell, Read, Edit, Write, Glob, Grep, NotebookEdit |
+| Agent 交互 | Agent, AskUserQuestion |
+| 任务管理 | TaskOutput, TaskStop, TaskCreate, TaskGet, TaskList, TaskUpdate, TodoWrite |
+| 规划 | EnterPlanMode, ExitPlanMode, VerifyPlanExecution |
+| Web | WebFetch, WebSearch |
+| 代码智能 | LSP |
+| 技能 | Skill |
+| 调度/监控 | Sleep |
+| 工具发现 | SearchExtraTools, ExecuteExtraTool, SyntheticOutput |
+
+**isDeferredTool 判定逻辑**（`packages/builtin-tools/src/tools/SearchExtraToolsTool/prompt.ts`）：
+
+```
+isDeferredTool(tool) =
+  tool.alwaysLoad === true?  → false（显式跳过延迟）
+  CORE_TOOLS.has(tool.name)? → false（核心工具不延迟）
+  otherwise                  → true（其余全部延迟）

+```
+
+### 3.3 搜索引擎设计
+
+SearchExtraToolsTool 支持四种查询模式：
+
+| 模式 | 语法 | 行为 | 返回 |
+|------|------|------|------|
+| **Select** | `select:CronCreate,Snip` | 按名称直接获取，逗号分隔多选 | 精确匹配列表 |
+| **Discover** | `discover:schedule cron job` | 纯发现模式，返回描述+schema | 工具信息文本 |
+| **Keyword** | `notebook jupyter` | 关键词搜索 | 按相关性排序 |
+| **Required** | `+slack send` | `+` 前缀强制包含 | 包含必选词的结果 |
+
+**混合搜索算法**：
+
+```
+最终分数 = 关键词分数 × 0.4 + TF-IDF 分数 × 0.6
+```
+
+- **Keyword Search**：基于工具名解析（CamelCase 分词、MCP 前缀拆解）、searchHint 匹配、描述文本匹配，加权计分
+- **TF-IDF Search**：复用 `skillSearch/localSearch.ts` 的算法，对 name (3.0)、searchHint (2.5)、description (1.0) 三个字段加权计算 TF-IDF 向量
+
+**MCP 工具名解析**：
+
+```
+mcp__slack__send_message → parts: ["slack", "send", "message"]
+CamelCase → parts: ["cron", "create"]
+```
+
+### 3.4 执行管道
+
+```
+模型调用 ExecuteExtraTool({tool_name: "CronCreate", params: {...}})
+  ↓
+ExecuteTool.call() 在全局工具注册表中查找 CronCreate
+  ↓
+检查目标工具 isEnabled() — 桥接/条件工具可能不可用
+  ↓
+委托目标工具的 checkPermissions() — 权限传递给实际工具
+  ↓
+调用目标工具的 call() — 与直接调用完全等价
+  ↓
+返回结果（包装为 ExecuteExtraTool 的 output schema）
+```
+
+关键设计：ExecuteExtraTool 的 `checkPermissions()` 返回 `passthrough`，将权限决策完全委托给目标工具。它本身不引入额外的权限层。
+
+### 3.5 Prompt Cache 稳定性策略（v3 关键修复）
+
+**问题**：早期版本在发现 deferred tool 后会将其注入 API tools 数组，导致每次发现新工具时 tools JSON 变化，prompt cache 全面失效。
+
+**修复**（commit `c14b7ead`）：deferred tools **始终不进入 API tools 数组**。tools 数组在整个会话中只包含 core tools + SearchExtraTools + ExecuteExtraTool，保持稳定。
+
+```
+API Tools 数组（会话期间不变）:
+  [Core Tools (29)] + [SearchExtraTools, ExecuteExtraTool, SyntheticOutput]
+  
+  不包含: 任何 deferred tool（即使已被发现）
+  执行方式: 通过 ExecuteExtraTool 代理调用
+```
+
+## 4. 预取机制（Prefetch）
+
+### 4.1 两个触发时机
+
+1. **Turn-zero**（`getTurnZeroSearchExtraToolsPrefetch`）— 用户输入第一轮时，基于输入文本搜索相关 deferred tools，以 attachment 形式注入
+2. **Inter-turn**（`startSearchExtraToolsPrefetch`）— assistant turn 结束后，基于对话上下文异步搜索
+
+### 4.2 Attachment 管道
+
+```
+prefetch → Attachment(type: 'tool_discovery')
+  → messages.ts 转换为 system-reminder
+  → "The following tools were discovered... Use ExecuteExtraTool to invoke..."
+```
+
+### 4.3 会话去重
+
+`discoveredToolsThisSession` Set 跟踪已发现的工具，避免重复推荐。该 Set 独立于 skill prefetch 的去重集合，互不影响。使用 `addBoundedSessionEntry()` 保持上限 500 条，超出时裁剪到 400 条。
+
+## 5. 模式切换系统
+
+通过环境变量 `ENABLE_SEARCH_EXTRA_TOOLS` 控制：
+
+| 环境变量值 | 模式 | 行为 |
+|-----------|------|------|
+| 未设置 | `tst` | 默认启用，始终延迟非核心工具 |
+| `true` | `tst` | 强制启用 |
+| `false` | `standard` | 完全禁用，所有工具内联加载 |
+| `auto` | `tst-auto` | 仅当 deferred tools 超过上下文窗口 10% 时启用 |
+| `auto:N` | `tst-auto` | 自定义阈值百分比（N=0 启用，N=100 禁用） |
+| `CLAUDE_CODE_DISABLE_EXPERIMENTAL_BETAS=1` | `standard` | 全局 kill switch |
+
+`isSearchExtraToolsEnabledOptimistic()` — 快速判断（不检查阈值），用于工具注册
+`isSearchExtraToolsEnabled()` — 完整判断（含阈值检查），用于 API 调用
+
+## 6. Deferred Tools Delta 机制
+
+对于 Anthropic 内部用户（`USER_TYPE=ant`）或启用了 `tengu_glacier_2xr` feature flag 的用户，使用 **delta attachment** 替代 `<available-deferred-tools>` 头部注入：
+
+- 首次：注入完整的 deferred tools 列表
+- 后续：只注入增量变化（新增/移除）
+- 优势：不会因为工具池变化导致整个头部缓存失效
+
+Delta attachment 扫描历史消息中的 `deferred_tools_delta` 类型 attachment，重建已宣告集合，然后差分计算当前 deferred pool 的变化。
+
+## 7. 演进历史
+
+### v1: 基础设施层（`7be08f53`）
+
+**34 个文件，+4040/-90 行**
+
+- 定义 `CORE_TOOLS` 白名单（31 个核心工具）
+- 实现 TF-IDF 工具索引模块 `toolIndex.ts`
+- 创建 `ExecuteTool` 作为统一执行入口
+- 增强 ToolSearchTool：TF-IDF 搜索路径、discover 模式、并行搜索合并
+- 新增 27 个单元测试
+- 实现预取管道和 UI 组件
+
+**关键文件**：
+- `src/services/toolSearch/toolIndex.ts` → 后续重命名为 `searchExtraTools/toolIndex.ts`
+- `packages/builtin-tools/src/tools/ExecuteTool/` — 执行入口
+- `src/constants/tools.ts` — CORE_TOOLS 定义
+
+### v2: 统一自建搜索（`8c157f07`）
+
+**17 个文件，+274/-395 行**（净减少 121 行）
+
+- **移除 `tool_reference` blocks** — 不再依赖 Anthropic API 的 `tool_reference` 功能
+- **移除 `defer_loading` 字段** — 不再发送 API 级别的工具延迟加载标记
+- **移除 `modelSupportsToolReference()`** — 不再区分模型是否支持 tool_reference
+- **重命名 ExecuteTool → ExecuteExtraTool** — 更清晰地表达其作为代理执行器的角色
+- **输出改为纯文本** — 所有 provider 通用，无需特殊 API 功能支持
+- **简化 system prompt** — 工具使用指南从 ~120 行压缩到 ~10 行
+
+**设计决策**：这次重构的核心洞察是 — 依赖 Anthropic 私有 API 特性（tool_reference、defer_loading、beta header）使得系统只能用于 first-party provider。自建 TF-IDF + keyword 搜索完全能满足需求，且对所有 provider（OpenAI、Gemini、Grok）通用。
+
+### v3: Cache 稳定性修复（`c14b7ead`）
+
+**7 个文件，+46/-31 行**
+
+- **移除 "discover then include" 逻辑** — 发现的 deferred tools 不再注入 tools 数组
+- **tools 数组保持稳定** — 只有 core tools + SearchExtraTools + ExecuteExtraTool
+- **强化优先级引导** — core tools 直接调用，ToolSearch 仅作为发现 deferred tools 的手段
+- **已加载工具拒绝提示** — 搜索 core tool 时返回明确拒绝
+
+**设计决策**：prompt cache 是 Claude Code 性能优化的关键。每次 tools JSON 变化都会导致缓存失效，代价远大于通过 ExecuteExtraTool 代理调用 deferred tools 的额外 token。因此选择牺牲一点直接调用的便利性，换取 cache 稳定性。
+
+### v4: Agents/Teams 延迟化（`af0d7dc8`）
+
+**7 个文件，+36/-18 行**
+
+- 将 `TeamCreate`、`TeamDelete`、`SendMessage` 从 CORE_TOOLS 移除
+- 这些工具仅在 swarm 模式下常用，平时占用 context token
+- swarm 模式下 SendMessage 保持 always loaded
+- TeamCreate/TeamDelete 在 swarm 未启用时返回启用提示
+
+**设计决策**：不是所有用户都需要团队功能。将其延迟化后，大部分用户可以节省约 3 个工具定义的 token 开销。
+
+## 8. 文件索引
+
+### 核心文件
+
+| 文件 | 职责 |
+|------|------|
+| `src/constants/tools.ts` | CORE_TOOLS 白名单、工具权限集合 |
+| `src/utils/searchExtraTools.ts` | 模式判定、阈值计算、delta 差分、discovered tools 提取 |
+| `src/services/searchExtraTools/toolIndex.ts` | TF-IDF 索引构建和搜索 |
+| `src/services/searchExtraTools/prefetch.ts` | 预取管道（turn-zero + inter-turn） |
+| `packages/builtin-tools/src/tools/SearchExtraToolsTool/` | 搜索工具实现（4 种查询模式） |
+| `packages/builtin-tools/src/tools/ExecuteTool/` | 代理执行器实现 |
+| `src/services/api/claude.ts` | API 层集成（工具过滤、消息归一化） |
+| `src/query.ts` | 查询循环集成（预取触发点） |
+| `src/utils/messages.ts` | Attachment → system-reminder 转换 |
+
+### 共享基础设施
+
+| 文件 | 被复用的导出 |
+|------|-------------|
+| `src/services/skillSearch/localSearch.ts` | `tokenizeAndStem`, `computeWeightedTf`, `computeIdf`, `cosineSimilarity` |
+| `src/services/skillSearch/prefetch.ts` | `extractQueryFromMessages` |
+
+### 测试文件
+
+| 文件 | 覆盖范围 |
+|------|---------|
+| `src/services/searchExtraTools/__tests__/toolIndex.test.ts` | 索引构建、TF-IDF 搜索、CJK 处理 |
+| `src/services/searchExtraTools/__tests__/prefetch.test.ts` | 预取管道、去重、attachment 生成 |
+| `packages/builtin-tools/src/tools/SearchExtraToolsTool/__tests__/` | 搜索工具 4 种模式 |
+| `packages/builtin-tools/src/tools/ExecuteTool/__tests__/` | 代理执行 |
+
+## 9. 维护指南
+
+### 9.1 新增工具的延迟化决策
+
+将新工具加入 deferred 状态的标准：
+- 工具仅在特定场景使用（如 swarm 模式、特定 MCP 集成）
+- 工具的 schema 较大（占用较多 context token）
+- 工具不是模型默认会尝试的核心操作
+
+将已延迟的工具提升为 core tool：
+- 在 `src/constants/tools.ts` 的 `CORE_TOOLS` Set 中添加工具名常量
+- 确保导入对应的 `*_TOOL_NAME` 常量
+
+### 9.2 修改注意事项
+
+1. **修改 `localSearch.ts` 的 TF-IDF 函数**：需同步检查 `toolIndex.test.ts` 和 `localSearch.test.ts`
+2. **修改 `skillSearch/prefetch.ts` 的 `extractQueryFromMessages`**：需同步检查工具预取行为（`searchExtraTools/prefetch.ts` 调用同一函数）
+3. **修改 CORE_TOOLS**：需更新 `src/constants/__tests__/tools.test.ts` 测试
+4. **修改 `isDeferredTool`**：需更新 `src/constants/__tests__/tools.test.ts` 和 `SearchExtraToolsTool.test.ts`
+
+### 9.3 性能优化配置
+
+```bash
+# 环境变量调优
+ENABLE_SEARCH_EXTRA_TOOLS=auto:15    # 当 deferred tools 超过上下文 15% 时启用
+SEARCH_EXTRA_TOOLS_WEIGHT_KEYWORD=0.5  # 关键词搜索权重
+SEARCH_EXTRA_TOOLS_WEIGHT_TFIDF=0.5    # TF-IDF 搜索权重
+SEARCH_EXTRA_TOOLS_DISPLAY_MIN_SCORE=0.10  # 最低显示分数阈值
+```
+
+### 9.4 搜索质量调优
+
+- `TOOL_FIELD_WEIGHT`（`toolIndex.ts`）：控制 name/searchHint/description 对 TF-IDF 分数的贡献权重
+- `KEYWORD_WEIGHT` / `TFIDF_WEIGHT`（`SearchExtraToolsTool.ts`）：控制混合搜索中两种算法的最终权重比例
+- `searchHint` 属性：为工具添加精心编写的搜索提示，提高关键词匹配质量
+
+## 10. 与 Skill Search 的关系
+
+ToolSearch 和 SkillSearch 是平行的搜索系统，共享底层算法但服务于不同领域：
+
+| 维度 | ToolSearch | SkillSearch |
+|------|-----------|-------------|
+| 搜索对象 | Deferred 工具（内置 + MCP） | 用户技能（skill） |
+| 执行方式 | `ExecuteExtraTool` 代理调用 | 直接注入 attachment 内容 |
+| 字段权重 | name:3.0, searchHint:2.5, desc:1.0 | name:3.0, whenToUse:2.0, desc:1.0 |
+| 缓存策略 | 按工具名列表缓存 | 按 cwd 缓存 |
+| 去重集合 | `discoveredToolsThisSession` | 独立的 Set |
+
+共享的底层函数：
+- `tokenizeAndStem` — 统一的 CJK/ASCII 分词和词干提取
+- `computeWeightedTf` — 加权词频计算
+- `computeIdf` — 逆文档频率计算
+- `cosineSimilarity` — 向量余弦相似度
+- `extractQueryFromMessages` — 从对话历史中提取搜索查询文本

+# `/autofix-pr` 命令实现规格文档
+
+> **状态**：规划阶段（2026-04-29），等待评审通过后进入实施。
+> **Worktree**：`E:\Source_code\Claude-code-bast-autofix-pr`，分支 `feat/autofix-pr`，基于 `origin/main` 4f1649e2。
+> **架构**：R（Remote-via-CCR），完整版（含 stop 子命令、单例锁、subscribePR、in-process teammate、skills 探测）。
+
+---
+
+## 一、背景
+
+### 1.1 问题
+
+本仓库（`Claude-code-bast`）是 Anthropic 官方 `@anthropic-ai/claude-code` 的反编译/重构版本。许多远程能力被 stub 化处理 —— `/autofix-pr` 是其中之一：
+
+```js
+// src/commands/autofix-pr/index.js（当前 stub）
+export default { isEnabled: () => false, isHidden: true, name: 'stub' };
+```
+
+三个字段共同导致命令在斜杠菜单中完全不可见、不可调起：
+
+| 字段 | 值 | 效果 |
+|---|---|---|
+| `isEnabled` | `() => false` | 注册时被判定不可用 |
+| `isHidden` | `true` | 即使被列出也被过滤 |
+| `name` | `'stub'` | 实际注册名是 `'stub'`，输入 `/autofix-pr` 无法匹配 |
+
+### 1.2 用户场景
+
+用户在 fork 仓库（`feat/autonomy-lifecycle-upstream` 分支）尝试对上游 `claude-code-best/claude-code#386` 跑 `/autofix-pr 386`，多次报 `git_repository source setup error`。根因：官方派发的远程 session 落在被 MCP 拒绝访问的仓库（`amdosion/claude-code-bast`），权限/可见性问题。
+
+### 1.3 目标
+
+| ID | 需求 | 验收 |
+|---|---|---|
+| R1 | 命令在斜杠菜单可见可调起 | 输入 `/au` 出现补全 |
+| R2 | 跨仓库 PR：从本地 fork 触发对上游 PR 的修复 | `/autofix-pr 386` 不报 repo-not-allowed |
+| R3 | 远端真正完成修复并 push 回 PR 分支 | PR 出现来自远端的新 commit |
+| R4 | 不破坏现存其他 stub（如 `share`） | 只动 `autofix-pr` |
+| R5 | TypeScript 严格模式，`bun run typecheck` 零错误 | CI 绿 |
+| R6 | bridge 可触发（Remote Control 场景） | `bridgeSafe: true` 生效 |
+| R7 | 支持 stop/off 子命令 | `/autofix-pr stop` 能终止当前监控 |
+| R8 | 单例锁防止重复派发 | 已监控 PR 时拒绝新启动并提示 |
+
+---
+
+## 二、反编译调研结论（来源：`C:\Users\12180\.local\bin\claude.exe`）
+
+`claude.exe` 是 242MB 的 Bun 原生编译产物（JS 源码 embed 在二进制内）。通过对该文件的字符串提取（`grep -aoE`）反推出完整调用链。
+
+### 2.1 主入口函数结构
+
+```js
+async function entry(input, q, ctx) {
+  const isStop = input === "stop" || input === "off"
+  const args = { freeformPrompt: input }
+  return main(args, q, ctx)
+}
+
+async function main(args, q, { signal, onProgress }) {
+  // args 字段：{ prNumber, target, freeformPrompt, repoPath, skills }
+  d("tengu_autofix_pr_started", {
+    action: "start",
+    has_pr_number: String(args.prNumber !== undefined),
+    has_repo_path: String(args.repoPath !== undefined),
+  })
+  // ...
+}
+```
+
+### 2.2 `teleportToRemote` 调用签名（黄金证据）
+
+```ts
+const session = await teleportToRemote({
+  initialMessage: C,                       // 给远端的初始消息
+  source: "autofix_pr",                    // ⚠️ 新字段，本仓库 teleport.tsx 没有
+  branchName: N,                           // PR 头分支
+  reuseOutcomeBranch: N,                   // 与 branchName 同 — 远端 push 回原分支
+  title: `Autofix PR: ${owner}/${repo}#${prNumber} (${branch})`,
+  useDefaultEnvironment: true,             // ⚠️ 不用 synthetic env（与 ultrareview 不同）
+  signal,
+  githubPr: { owner, repo, number },
+  cwd: repoPath,
+  onBundleFail: (msg) => { /* ... */ },
+})
+```
+
+**与 `ultrareview` 的关键差异**：
+
+| 字段 | ultrareview | autofix-pr |
+|---|---|---|
+| `environmentId` | `env_011111111111111111111113`（synthetic） | 不传 |
+| `useDefaultEnvironment` | 不传 | `true` |
+| `useBundle` | 有（branch mode） | 不传（`skipBundle` 隐含于不传 bundle） |
+| `reuseOutcomeBranch` | 不传 | 传（远端 push 回原 PR 分支） |
+| `githubPr` | 不传 | 必传 |
+| `source` | 不传 | `"autofix_pr"` |
+| `environmentVariables` | `BUGHUNTER_*` 一堆 | 不传 |
+
+### 2.3 `registerRemoteAgentTask` 调用
+
+```ts
+registerRemoteAgentTask({
+  remoteTaskType: "autofix-pr",
+  session: { id: session.id, title: session.title },
+  command,
+  isLongRunning: true,        // poll 不消费 result，靠通知周期驱动
+})
+```
+
+### 2.4 子命令解析
+
+```
+/autofix-pr <PR#>                    → 启动监控 + 派 CCR session
+/autofix-pr stop                     → 停止当前监控
+/autofix-pr off                      → 同 stop
+/autofix-pr <freeform-prompt>        → 自由 prompt 模式（无 PR 号）
+/autofix-pr <owner>/<repo>#<n>       → 跨仓库（覆盖 R2 验收）
+```
+
+### 2.5 状态模型
+
+- **单例锁**：同一时刻只能监控一个 PR。重复启动报：`already monitoring ${repo}#${prNumber}. Run /autofix-pr stop first.`（error_code: `rc_already_monitoring_other`）
+- **PR 订阅**：调 `kairos.subscribePR(owner, repo, taskId)` —— 依赖 `KAIROS_GITHUB_WEBHOOKS` feature flag（用户已订阅，可用）
+- **in-process teammate**：注册后台 agent
+  ```ts
+  const teammate = {
+    agentId,
+    agentName: "autofix-pr",
+    teamName: "_autofix",
+    color: undefined,
+    planModeRequired: false,
+    parentSessionId,
+  }
+  ```
+- **Skills 探测**：扫项目里 autofix-related skills（如 `.claude/skills/autofix-*` 或根目录 `AUTOFIX.md`），命中后拼到 prompt：`Run X and Y for custom instructions on how to autofix.`
+
+### 2.6 Telemetry
+
+| 事件 | 字段 |
+|---|---|
+| `tengu_autofix_pr_started` | `{ action, has_pr_number, has_repo_path }` |
+| `tengu_autofix_pr_result` | `{ result, error_code? }` |
+
+`result` 取值：`success_rc` / `failed` / `cancelled`
+
+`error_code` 取值：
+
+| code | 含义 |
+|---|---|
+| `rc_already_monitoring_other` | 已在监控其他 PR |
+| `session_create_failed` | teleport 失败 |
+| `exception` | 未捕获异常 |
+
+### 2.7 错误返回结构
+
+```ts
+function errorResult(message: string, code: string) {
+  d("tengu_autofix_pr_result", { result: "failed", error_code: code })
+  return {
+    kind: "error",
+    message: `Autofix PR failed: ${message}`,
+    code,
+  }
+}
+
+function cancelledResult() {
+  d("tengu_autofix_pr_result", { result: "cancelled" })
+  return { kind: "cancelled" }
+}
+```
+
+---
+
+## 三、本仓库现有基础设施盘点
+
+下表列出实现 `/autofix-pr` 时**直接复用**的现成能力（已确认完整可用）：
+
+| 能力 | 文件 | 角色 |
+|---|---|---|
+| `teleportToRemote` | `src/utils/teleport.tsx:947` | 派 CCR 远端 session（缺 `source` 字段，需补） |
+| `registerRemoteAgentTask` | `src/tasks/RemoteAgentTask/RemoteAgentTask.tsx:526` | 注册 long-running 任务到 store |
+| `checkRemoteAgentEligibility` | `src/tasks/RemoteAgentTask/RemoteAgentTask.tsx:185` | 前置鉴权检查 |
+| `getRemoteTaskSessionUrl` | `src/tasks/RemoteAgentTask/RemoteAgentTask.tsx` | 生成 session 跟踪 URL |
+| `formatPreconditionError` | `src/tasks/RemoteAgentTask/RemoteAgentTask.tsx` | 错误文案格式化 |
+| `REMOTE_TASK_TYPES` | `src/tasks/RemoteAgentTask/RemoteAgentTask.tsx:103` | 已含 `'autofix-pr'` 类型 |
+| `AutofixPrRemoteTaskMetadata` | `src/tasks/RemoteAgentTask/RemoteAgentTask.tsx:112` | `{ owner, repo, prNumber }` schema |
+| `RemoteSessionProgress` | `src/components/tasks/RemoteSessionProgress.tsx` | 进度面板 UI（已认 autofix-pr 类型） |
+| `detectCurrentRepositoryWithHost` | `src/utils/detectRepository.ts` | 解析 owner/repo |
+| `getDefaultBranch` / `gitExe` | `src/utils/git.ts` | git 工具 |
+| `feature('FLAG')` | `bun:bundle` | feature flag 系统（CLAUDE.md 红线：只能在 if/三元条件位置直接调用） |
+
+### 模板答案文件
+
+以下三个文件已确认完整工作，是本次实现的"参考答案"：
+
+- `src/commands/review/reviewRemote.ts`（317 行）—— **主模板**，照抄改造
+- `src/commands/ultraplan.tsx`（525 行）
+- `src/commands/review/ultrareviewCommand.tsx`（89 行）
+
+---
+
+## 四、命令对象规格
+
+### 4.1 `Command` 类型选择
+
+`Command` 类型定义在 `src/types/command.ts`，三态之一：`PromptCommand` / `LocalCommand` / `LocalJSXCommand`。
+
+**选 `LocalJSXCommand`**，因为：
+- 需要 spawn 远端 session 并显示进度面板
+- 兄弟命令 `ultraplan` / `ultrareview` 都用 local-jsx
+- 接口签名：`call(onDone, context, args) => Promise<React.ReactNode>`
+
+### 4.2 `index.ts` 完整形状
+
+```ts
+import { feature } from 'bun:bundle'
+import type { Command } from '../../types/command.js'
+
+const autofixPr: Command = {
+  type: 'local-jsx',
+  name: 'autofix-pr',                          // 关键：必须是 'autofix-pr' 不是 'stub'
+  description: 'Auto-fix CI failures on a pull request',
+  argumentHint: '<pr-number> | stop | <owner>/<repo>#<n>',
+  isEnabled: () => feature('AUTOFIX_PR'),
+  isHidden: false,
+  bridgeSafe: true,
+  getBridgeInvocationError: (args) => {
+    const trimmed = args.trim()
+    if (!trimmed) return 'PR number required, e.g. /autofix-pr 386'
+    if (trimmed === 'stop' || trimmed === 'off') return undefined
+    if (/^\d+$/.test(trimmed)) return undefined
+    if (/^[\w.-]+\/[\w.-]+#\d+$/.test(trimmed)) return undefined
+    return 'Invalid args. Use /autofix-pr <pr-number> | stop | <owner>/<repo>#<n>'
+  },
+  load: async () => {
+    const m = await import('./launchAutofixPr.js')
+    return { call: m.callAutofixPr }
+  },
+}
+
+export default autofixPr
+```
+
+### 4.3 参数解析规则
+
+```
+^stop$ | ^off$            → { action: 'stop' }
+^\d+$                     → { action: 'start', prNumber, owner: <git>, repo: <git> }
+^([\w.-]+)/([\w.-]+)#(\d+)$ → { action: 'start', prNumber, owner, repo }
+其他                       → { action: 'start', freeformPrompt: <input> }
+空字符串                   → 错误
+```
+
+---
+
+## 五、文件结构
+
+```
+src/commands/autofix-pr/
+├── index.ts                       # 命令对象（替换 index.js）
+├── launchAutofixPr.ts             # 主流程
+├── parseArgs.ts                   # 参数解析（独立便于测试）
+├── monitorState.ts                # 单例锁
+├── inProcessAgent.ts              # 后台 teammate
+├── skillDetect.ts                 # 项目 skills 探测
+└── __tests__/
+    ├── parseArgs.test.ts
+    ├── monitorState.test.ts
+    ├── launchAutofixPr.test.ts
+    └── index.test.ts              # bridge invocation error 测试
+```
+
+**删除**：原 `index.js`、`index.d.ts`（合并进 `index.ts`）。
+
+**修改**：
+- `scripts/defines.ts` —— 加 `AUTOFIX_PR` flag
+- `scripts/dev.ts` —— dev 默认开启
+- `src/utils/teleport.tsx` —— `teleportToRemote` 选项加 `source?: string` 字段并透传
+- `src/commands.ts` —— **不动**（import 路径 `'./commands/autofix-pr/index.js'` 在 ESM/Bun 下会自动解析到 `.ts`）
+
+---
+
+## 六、模块详细规格
+
+### 6.1 `parseArgs.ts`
+
+```ts
+export type ParsedArgs =
+  | { action: 'stop' }
+  | { action: 'start'; prNumber: number; owner?: string; repo?: string }
+  | { action: 'freeform'; prompt: string }
+  | { action: 'invalid'; reason: string }
+
+export function parseAutofixArgs(raw: string): ParsedArgs {
+  const trimmed = raw.trim()
+  if (!trimmed) return { action: 'invalid', reason: 'empty' }
+  if (trimmed === 'stop' || trimmed === 'off') return { action: 'stop' }
+  if (/^\d+$/.test(trimmed)) {
+    return { action: 'start', prNumber: parseInt(trimmed, 10) }
+  }
+  const cross = trimmed.match(/^([\w.-]+)\/([\w.-]+)#(\d+)$/)
+  if (cross) {
+    return {
+      action: 'start',
+      owner: cross[1],
+      repo: cross[2],
+      prNumber: parseInt(cross[3], 10),
+    }
+  }
+  return { action: 'freeform', prompt: trimmed }
+}
+```
+
+### 6.2 `monitorState.ts`
+
+```ts
+import type { UUID } from 'crypto'
+
+type MonitorState = {
+  taskId: UUID
+  owner: string
+  repo: string
+  prNumber: number
+  abortController: AbortController
+  startedAt: number
+}
+
+let active: MonitorState | null = null
+
+export function getActiveMonitor(): Readonly<MonitorState> | null {
+  return active
+}
+
+export function setActiveMonitor(state: MonitorState): void {
+  if (active) throw new Error(`Monitor already active: ${active.repo}#${active.prNumber}`)
+  active = state
+}
+
+export function clearActiveMonitor(): void {
+  if (active) {
+    active.abortController.abort()
+    active = null
+  }
+}
+
+export function isMonitoring(owner: string, repo: string, prNumber: number): boolean {
+  return active?.owner === owner && active?.repo === repo && active?.prNumber === prNumber
+}
+```
+
+### 6.3 `inProcessAgent.ts`
+
+仿官方 `xd9` 函数：
+
+```ts
+import { randomUUID, type UUID } from 'crypto'

+### 6.6 `teleport.tsx` 补 `source` 字段
+
+```diff
+ export async function teleportToRemote(options: {
+   initialMessage: string | null
+   branchName?: string
+   title?: string
+   description?: string
++  /**
++   * Identifies which command/flow originated this teleport. CCR backend
++   * uses this for routing/billing/observability. Known values: 'autofix_pr',
++   * 'ultrareview', 'ultraplan'. Pass-through field — not interpreted client-side.
++   */
++  source?: string
+   model?: string
+   permissionMode?: PermissionMode
+   // ...
+ })
+```
+
+并在内部构造 request 时透传到 session_context（具体字段名按现有 review/ultraplan 调用结构对齐）。
+
+---
+
+## 七、Feature Flag
+
+### 7.1 新增 flag
+
+`scripts/defines.ts` 已有的 flag 集合中加 `AUTOFIX_PR`。
+
+### 7.2 启用矩阵
+
+| 环境 | 是否默认开启 | 说明 |
+|---|---|---|
+| dev (`bun run dev`) | 是 | `scripts/dev.ts` 加进默认列表 |
+| build (production `bun run build`) | 否 | 灰度上线，需要 `FEATURE_AUTOFIX_PR=1` 显式开启 |
+| 测试 | 按需 | 测试文件通过 mock `bun:bundle` 控制 |
+
+### 7.3 与官方上游同步策略
+
+如果上游某天恢复官方实现，本仓库的本地实现优先（项目即 fork）：
+1. 保留 `AUTOFIX_PR` flag 名
+2. 保留 `RemoteTaskType` 字段不动
+3. 冲突时合并：吸收上游的 `source` 字段值变更、env var 变更，保留我们的本地 launcher 函数
+
+---
+
+## 八、测试计划
+
+### 8.1 测试文件
+
+| 文件 | 覆盖目标 | 测试用例数 |
+|---|---|---|
+| `parseArgs.test.ts` | 参数解析全分支 | ~10 |
+| `monitorState.test.ts` | 单例锁正确性 | ~6 |
+| `launchAutofixPr.test.ts` | 主流程 happy path + 失败路径 | ~12 |
+| `index.test.ts` | bridge invocation error 校验 | ~5 |
+
+### 8.2 关键断言
+
+`launchAutofixPr.test.ts`：
+
+```ts
+test('start with PR number teleports with correct args', async () => {
+  // mock teleportToRemote, registerRemoteAgentTask, detectCurrentRepositoryWithHost
+  await callAutofixPr(onDone, context, '386')
+  expect(teleportMock).toHaveBeenCalledWith(expect.objectContaining({
+    source: 'autofix_pr',
+    useDefaultEnvironment: true,
+    githubPr: { owner: 'amDosion', repo: 'claude-code-bast', number: 386 },
+    branchName: 'refs/pull/386/head',
+    reuseOutcomeBranch: 'refs/pull/386/head',
+  }))
+  expect(registerMock).toHaveBeenCalledWith(expect.objectContaining({
+    remoteTaskType: 'autofix-pr',
+  }))
+})
+
+test('cross-repo syntax owner/repo#n parses correctly', async () => {
+  await callAutofixPr(onDone, context, 'anthropics/claude-code#999')
+  expect(teleportMock).toHaveBeenCalledWith(expect.objectContaining({
+    githubPr: { owner: 'anthropics', repo: 'claude-code', number: 999 },
+  }))
+})
+
+test('singleton lock blocks second start', async () => {
+  await callAutofixPr(onDone, context, '386')
+  const result = await callAutofixPr(onDone, context, '999')
+  expect(extractError(result)).toMatch(/already monitoring.*386.*Run \/autofix-pr stop first/)
+})
+
+test('stop clears active monitor', async () => {
+  await callAutofixPr(onDone, context, '386')
+  await callAutofixPr(onDone, context, 'stop')
+  expect(getActiveMonitor()).toBeNull()
+})
+```
+
+### 8.3 Mock 策略
+
+按本仓库 `tests/mocks/` 共享 mock 习惯：
+- `tests/mocks/log.ts` 和 `tests/mocks/debug.ts` —— 必 mock
+- `bun:bundle` —— mock `feature` 返回 `true`
+- `teleportToRemote` —— 模块级 mock，断言入参
+- `registerRemoteAgentTask` —— 模块级 mock，断言入参
+- `detectCurrentRepositoryWithHost` —— mock 返回 `{ owner, name, host }`
+
+### 8.4 类型检查
+
+```bash
+bun run typecheck      # 必须零错误
+bun run test:all       # 必须全绿
+```
+
+---
+
+## 九、实施步骤（11 步清单）
+
+```
+[ ] Step 1   scripts/defines.ts + scripts/dev.ts 加 AUTOFIX_PR flag
+[ ] Step 2   src/utils/teleport.tsx 加 source?: string 字段（约 5 行）
+[ ] Step 3   删除 src/commands/autofix-pr/{index.js, index.d.ts}
+             新建 src/commands/autofix-pr/index.ts（约 50 行）
+[ ] Step 4   新建 src/commands/autofix-pr/parseArgs.ts（约 30 行）
+[ ] Step 5   新建 src/commands/autofix-pr/monitorState.ts（约 40 行）
+[ ] Step 6   新建 src/commands/autofix-pr/inProcessAgent.ts（约 60 行）
+[ ] Step 7   新建 src/commands/autofix-pr/skillDetect.ts（约 30 行）
+[ ] Step 8   新建 src/commands/autofix-pr/launchAutofixPr.ts（约 250 行）
+             照抄 reviewRemote.ts，按 §2.2 差异表改造
+[ ] Step 9   新建四份测试文件（约 150 行）
+[ ] Step 10  bun run typecheck && bun run test:all 全绿
+[ ] Step 11  dev 模式手测：
+              a. /autofix-pr 386 → 期望出现 RemoteSessionProgress 面板
+              b. /autofix-pr stop → 期望提示已停止
+              c. /autofix-pr anthropics/claude-code#999 → 期望跨仓库
+              d. 第二次 /autofix-pr 386 → 期望被单例锁拒绝
+[ ] Step 12  commit：feat: implement /autofix-pr command (replace stub)
+```
+
+预计工作量：约 600 行新增代码（含测试 150 行）。
+
+---
+
+## 十、风险与回退
+
+| 风险 | 触发场景 | 回退策略 |
+|---|---|---|
+| `source` 字段 CCR 后端不识别 | 后端只认特定枚举 | 不传该字段，看是否能跑通；如不行回头看官方 cli.js 是否传了别的字段 |
+| `subscribePR` API 在本仓库 client 不完整 | KAIROS_GITHUB_WEBHOOKS 客户端代码缺失 | 用 `.catch(() => {})` 容忍失败，订阅是 nice-to-have |
+| 用户账号无 CCR 权限 | `checkRemoteAgentEligibility` 返回 false | 命令降级到错误文案，不破坏会话 |
+| 远端能起 session 但不修代码 | env vars 命名错误 | 看 `getRemoteTaskSessionUrl` 给的会话页容器日志，调整 |
+| PR 在 fork 仓库且 CCR 没访问权 | `git_repository source error` | 命令应在前置检查中识别并提示用户先把 PR 转到主仓 |
+| 上游恢复官方实现导致冲突 | 上游 sync 时 | 项目是 fork，本地实现优先；冲突手工 merge |
+
+### 回退命令
+
+```bash
+# 完全撤回本次实现
+git checkout main
+git worktree remove E:/Source_code/Claude-code-bast-autofix-pr
+git branch -D feat/autofix-pr
+```
+
+`AUTOFIX_PR` flag 默认在 production 关闭，所以即使代码已合入 main，没显式 `FEATURE_AUTOFIX_PR=1` 时不会影响用户。
+
+---
+
+## 十一、验收清单
+
+实施完成后逐项核对：
+
+- [ ] R1：dev 模式下输入 `/au` 出现 `/autofix-pr` 补全
+- [ ] R2：`/autofix-pr anthropics/claude-code#999` 不报 repo-not-allowed
+- [ ] R3：远端 session 跑完后目标 PR 出现新 commit
+- [ ] R4：其他 stub（`share` 等）依然 hidden
+- [ ] R5：`bun run typecheck` 零错误
+- [ ] R6：通过 RC bridge 触发 `/autofix-pr 386` 能跑通
+- [ ] R7：`/autofix-pr stop` 终止当前监控
+- [ ] R8：第二次 `/autofix-pr` 不同 PR 时被锁拒绝并提示

+
+## 测试前准备
+
+```bash
+cd E:/Source_code/Claude-code-bast-autofix-pr
+
+# 1. 确保最新 dist 含全部 commits
+bun run build
+
+# 2. 验证 dist 不是 stale
+stat -c '%Y %n' dist/cli.js
+git log -1 --format=%ct\ %h
+# dist mtime 必须 ≥ HEAD commit time
+
+# 3. 完全退出当前 dev REPL（按 Ctrl+D 或 /quit）后重启
+bun run dev
+```
+
+**关键提醒**：Bun 不会动态重载 dist，任何 source 改动都必须 `bun run build` + 重启 REPL。

+
+---
+
+## D 组 — _（已删除 2026-05-06）_
+
+`/providers` 命令在 2026-05-06 移除。理由:与 fork 原生 `/login` 的 "Anthropic Compatible Setup" form 功能重叠（同样配 OpenAI-compat Base URL + API Key），保留单一入口避免双 UI 混淆。
+
+**第三方 provider 配置请用** `/login` 内的 form:选 provider 后填 Base URL + API Key + Haiku/Sonnet/Opus 类别按钮。
+
+`src/services/providerRegistry/*` utility 模块 **保留**（4 内置 cerebras/groq/qwen/deepseek 元数据 + DeepSeek 三模式 compatMatrix），可被未来 fork form 的 "Quick Select" enhancement 复用。

 Skip plan mode when you can reasonably infer the right approach:
 - The task is straightforward even if it touches multiple files

-- You're adding a feature with an obvious implementation pattern (e.g., adding a button, a new endpoint following existing conventions)
+- You're adding a feature with an obvious implementation pattern
 - Bug fixes where the fix is clear once you understand the bug

 - The user says something like "can we work on X" or "let's do X" — just get started
 
 When in doubt, prefer starting work and using ${ASK_USER_QUESTION_TOOL_NAME} for specific questions over entering a full planning phase.

+ *   1. V8/Bun JavaScript runs JS on a single event-loop thread, so the
+ *      read-modify-write sequence here (get → check → maybe-evict → set)
+ *      is atomic with respect to other JS on the same thread. There is

+ *
+ *   2. We are NOT safe under multi-process / Worker concurrency. A

+ *      `FETCH_BUDGET_USED` Map; the budget is per-process. Tools are
+ *      not currently invoked across processes within one Claude turn,
+ *      so this is acceptable.
+ *
+ *   3. The budget is a SOFT limit: a crash mid-call can leak budget,
+ *      and the FIFO eviction makes the cap a heuristic, not a hard
+ *      enforcement. The HARD enforcement is the per-fetch byte cap
+ *      (FETCH_CAP_BYTES) and the per-list byte cap, which run inside
+ *      the call() body and are independent of this counter.
