 路径规则：统一用 `.ts` 扩展名 + `src/*` 别名路径，禁止双重 mock 同一模块。
 
+#### 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）：**
+- 测试文件执行顺序**不是严格字母序**，不要假设文件 A 一定在文件 B 之前执行。
+- `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。**
+
+错误做法（会污染同目录的 `api.test.ts`）：
+```ts
+// launchSchedule.test.ts — 直接 mock 源 API 模块 ❌
+mock.module('src/commands/schedule/triggersApi.js', () => ({
+  listTriggers: listTriggersMock,
+  // ...
+}))
+```
+
+正确做法（mock 底层 HTTP 层，不污染业务模块）：参考 `launchSkillStore.test.ts`、`launchVault.test.ts` 的模式。
+```ts
+// launchSchedule.test.ts — mock axios 而非 triggersApi ✅
+import { setupAxiosMock } from '../../../../tests/mocks/axios.js'
+
+const axiosHandle = setupAxiosMock()
+axiosHandle.stubs.get = axiosGetMock
+axiosHandle.stubs.post = axiosPostMock
+
+beforeAll(() => { axiosHandle.useStubs = true })
+afterAll(() => { axiosHandle.useStubs = false })
+```
+
+**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。
+
+**排查 mock 污染的方法：**
+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
+

+# `/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

+**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'
+import { getCurrentSessionId } from '../../bootstrap/state.js'
+
+export type AutofixTeammate = {
+  agentId: UUID
+  agentName: 'autofix-pr'
+  teamName: '_autofix'
+  color: undefined
+  planModeRequired: false
+  parentSessionId: UUID
+  abortController: AbortController
+  taskId: UUID
+}
+
+export function createAutofixTeammate(
+  initialMessage: string,
+  target: string,
+): AutofixTeammate {
+  return {
+    agentId: randomUUID(),
+    agentName: 'autofix-pr',
+    teamName: '_autofix',
+    color: undefined,
+    planModeRequired: false,
+    parentSessionId: getCurrentSessionId(),
+    abortController: new AbortController(),
+    taskId: randomUUID(),
+  }
+}
+```
+
+### 6.4 `skillDetect.ts`
+
+```ts
+import { existsSync } from 'fs'
+import { join } from 'path'
+
+export function detectAutofixSkills(cwd: string): string[] {
+  const candidates = [
+    'AUTOFIX.md',
+    '.claude/skills/autofix.md',
+    '.claude/skills/autofix-pr/SKILL.md',
+  ]
+  return candidates.filter(rel => existsSync(join(cwd, rel)))
+}
+
+export function formatSkillsHint(skills: string[]): string {
+  if (skills.length === 0) return ''
+  return ` Run ${skills.join(' and ')} for custom instructions on how to autofix.`
+}
+```
+
+### 6.5 `launchAutofixPr.ts`
+
+主流程伪代码（约 250 行）：
+
+```ts

+
+> **注意**：`feature('KAIROS_GITHUB_WEBHOOKS')` 必须直接放在 if 条件位置，不能赋值给变量（CLAUDE.md 红线）。
+
+### 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

+
+## 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。

+- AES 错 passphrase → 提示重新 setSecret
+- keychain 不可用 → 自动 fallback 文件（warn 一次）
+- path traversal 接受 → audit-fix-all-40 修复未生效，重新 build

+
+## F 组 — Workspace API key（需配 `ANTHROPIC_API_KEY=sk-ant-api03-*`）
+
+**前置**：
+1. 从 https://console.anthropic.com/settings/keys 创建 API key（`sk-ant-api03-*`）
+2. Windows: `setx ANTHROPIC_API_KEY "sk-ant-api03-..."` 持久化
+3. **完全退出 dev REPL**（Ctrl+D / `/quit`） + 启动新 shell（让 setx 生效）+ `bun run dev`

+| `/autofix-pr` cross-repo | 仅元数据，git source 仍来自 cwd（`repo_mismatch` 显式拒绝跨 cwd） |
+| `/skill-store install` | 写到 `~/.claude/skills/`，fork 主流程不自动 load 该目录的 markdown skills（用户手动用） |

+// (worst case: budget shared across multiple turns in the same session,
+// which is conservative — caps low).
+//
+// The Map is module-level. `consumeBudget` evicts oldest entries when the
+// cap is hit so memory stays bounded across long-running sessions.

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

+ *      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.

-IMPORTANT: ExecuteExtraTool is always available in your tool list. After this search returns tool names, you MUST call ExecuteExtraTool with {"tool_name": "<returned_name>", "params": {...}} to invoke the deferred tool. This is the ONLY way to execute deferred tools — do not read source code or analyze whether the tool is callable, just use ExecuteExtraTool directly.
+## Two-step workflow (MUST follow exactly)
 
-Query forms:
-- "select:CronCreate,Snip" — fetch these exact tools by name
-- "discover:schedule cron job" — pure discovery, returns tool info (name, description) without loading. Use when you want to understand available tools before deciding which to invoke.
+Deferred tools CANNOT be called directly. You MUST use this two-step pattern:
+
+Step 1 — Search: Call this tool (SearchExtraTools) to discover the target tool.
+  Input: {"query": "select:CronCreate"}
+  Response: "Found 1 deferred tool(s): CronCreate. Use ExecuteExtraTool with {"tool_name": "<name>", "params": {...}} to invoke."
+
+Step 2 — Execute: Call ExecuteExtraTool to run the discovered tool.
+  Input: {"tool_name": "CronCreate", "params": {"schedule": "*/5 * * * *", "prompt": "check the deploy"}}
+  Response: the actual tool result.
+
+## Example: user asks "schedule a cron to check deploy every 5 minutes"
+
+1. SearchExtraTools({"query": "select:CronCreate"})
+   → Response: Found deferred tool CronCreate
+2. ExecuteExtraTool({"tool_name": "CronCreate", "params": {"schedule": "*/5 * * * *", "prompt": "check the deploy"}})
+   → Response: Cron job created successfully
+
+If you don't know the exact tool name, use keyword search first:
+1. SearchExtraTools({"query": "cron schedule"})
+   → Response: Found deferred tool(s): CronCreate
+2. ExecuteExtraTool({"tool_name": "CronCreate", "params": {...}})
+
+## Query forms
+- "select:CronCreate" — exact tool name (fastest, preferred when you know the name from <available-deferred-tools>)
+- "select:CronCreate,CronList" — comma-separated multi-select
+- "discover:schedule cron job" — returns tool name + description + schema without loading. Use to understand a tool before calling it.
 - "notebook jupyter" — keyword search, up to max_results best matches
-- "+slack send" — require "slack" in the name, rank by remaining terms`
+- "+slack send" — require "slack" in the name, rank by remaining terms
+
+## Failure policy
+If ExecuteExtraTool fails, do NOT re-search for the same tool — it will loop. Stop and tell the user what failed.`
