feat(loop-monitor): implement dynamic tool loading for task modals

- Add getEnabledTools() async function to fetch tools from /api/cli/tools-config
- Cache enabled tools in window.enabledTools to avoid repeated API calls
- Replace hardcoded tool options in add task modal with dynamic generation
- Replace hardcoded tool options in edit task modal with dynamic generation
- Fallback to ['claude'] if no tools enabled, all tools if API fails
- Make showAddTaskModal() and showEditTaskModal() async functions
- Update editTask() to use await when calling showEditTaskModal()

Fixes issue where task modals only showed hardcoded tools instead of
loading enabled tools from CLI configuration.

+# CCW Loop Skill
+
+无状态迭代开发循环工作流，支持开发 (Develop)、调试 (Debug)、验证 (Validate) 三个阶段，每个阶段都有独立的文件记录进展。
+
+## Overview
+
+CCW Loop 是一个自主模式 (Autonomous) 的 Skill，通过文件驱动的无状态循环，帮助开发者系统化地完成开发任务。
+
+### 核心特性
+
+1. **无状态循环**: 每次执行从文件读取状态，不依赖内存
+2. **文件驱动**: 所有进度记录在 Markdown 文件中，可审计、可回顾
+3. **Gemini 辅助**: 关键决策点使用 CLI 工具进行深度分析
+4. **可恢复**: 任何时候中断后可继续
+5. **双模式**: 支持交互式和自动循环
+
+### 三大阶段
+
+- **Develop**: 任务分解 → 代码实现 → 进度记录
+- **Debug**: 假设生成 → 证据收集 → 根因分析 → 修复验证
+- **Validate**: 测试执行 → 覆盖率检查 → 质量评估
+
+## Installation
+
+已包含在 `.claude/skills/ccw-loop/`，无需额外安装。
+
+## Usage
+
+### 基本用法
+
+```bash
+# 启动新循环
+/ccw-loop "实现用户认证功能"
+
+# 继续现有循环
+/ccw-loop --resume LOOP-auth-2026-01-22
+
+# 自动循环模式
+/ccw-loop --auto "修复登录bug并添加测试"
+```
+
+### 交互式流程
+
+```
+1. 启动: /ccw-loop "任务描述"
+2. 初始化: 自动分析任务并生成子任务列表
+3. 显示菜单:
+   - 📝 继续开发 (Develop)
+   - 🔍 开始调试 (Debug)
+   - ✅ 运行验证 (Validate)
+   - 📊 查看详情 (Status)
+   - 🏁 完成循环 (Complete)
+   - 🚪 退出 (Exit)
+4. 执行选择的动作
+5. 重复步骤 3-4 直到完成
+```
+
+### 自动循环流程
+
+```
+Develop (所有任务) → Debug (如有需要) → Validate → 完成
+```

+## CLI Integration
+
+CCW Loop 在关键决策点集成 CLI 工具:
+
+### 任务分解 (action-init)
+```bash
+ccw cli -p "PURPOSE: 分解开发任务..."
+  --tool gemini
+  --mode analysis
+  --rule planning-breakdown-task-steps
+```
+
+### 代码实现 (action-develop)
+```bash
+ccw cli -p "PURPOSE: 实现功能代码..."
+  --tool gemini
+  --mode write
+  --rule development-implement-feature
+```
+
+### 假设生成 (action-debug - 探索)
+```bash
+ccw cli -p "PURPOSE: Generate debugging hypotheses..."
+  --tool gemini
+  --mode analysis
+  --rule analysis-diagnose-bug-root-cause
+```
+
+### 证据分析 (action-debug - 分析)
+```bash
+ccw cli -p "PURPOSE: Analyze debug log evidence..."
+  --tool gemini
+  --mode analysis
+  --rule analysis-diagnose-bug-root-cause
+```
+
+### 质量评估 (action-validate)
+```bash
+ccw cli -p "PURPOSE: Analyze test results and coverage..."
+  --tool gemini
+  --mode analysis
+  --rule analysis-review-code-quality
+```
+
+## State Management
+
+### State Schema
+
+参见 [phases/state-schema.md](phases/state-schema.md)
+
+### State Transitions
+
+```
+pending → running → completed
+              ↓
+         user_exit
+              ↓
+            failed
+```
+
+### State Recovery
+
+如果 `state.json` 损坏，可从其他文件重建:
+- develop/tasks.json → develop.*
+- debug/hypotheses.json → debug.*
+- validate/test-results.json → validate.*
+
+## Examples
+
+### Example 1: 功能开发
+
+```bash
+# 1. 启动循环
+/ccw-loop "Add user profile page"
+
+# 2. 系统初始化，生成任务:
+#    - task-001: Create profile component
+#    - task-002: Add API endpoints
+#    - task-003: Implement tests
+
+# 3. 选择 "继续开发"
+#    → 执行 task-001 (Gemini 辅助实现)
+#    → 更新 progress.md
+
+# 4. 重复开发直到所有任务完成
+
+# 5. 选择 "运行验证"
+#    → 运行测试
+#    → 检查覆盖率
+#    → 生成 validation.md
+
+# 6. 选择 "完成循环"

+```
+
+### Example 2: Bug 修复
+
+```bash
+# 1. 启动循环
+/ccw-loop "Fix login timeout issue"
+
+# 2. 选择 "开始调试"
+#    → 输入 bug 描述: "Login times out after 30s"
+#    → Gemini 生成假设 (H1, H2, H3)
+#    → 添加 NDJSON 日志
+#    → 提示复现 bug
+
+# 3. 复现 bug (在应用中操作)
+
+# 4. 再次选择 "开始调试"
+#    → 解析 debug.log
+#    → Gemini 分析证据
+#    → H2 确认为根因
+#    → 生成修复代码
+#    → 更新 understanding.md
+
+# 5. 选择 "运行验证"
+#    → 测试通过
+
+# 6. 完成

+## Integration
+
+### Dashboard Integration
+
+CCW Loop 与 Dashboard Loop Monitor 集成:
+- Dashboard 创建 Loop → 触发此 Skill
+- state.json → Dashboard 实时显示
+- 任务列表双向同步
+- 控制按钮映射到 actions
+
+### Issue System Integration
+
+完成后可扩展为 Issue:
+- 维度: test, enhance, refactor, doc
+- 自动调用 `/issue:new`
+- 上下文自动填充
+
+## Error Handling
+
+| 情况 | 处理 |
+|------|------|
+| Session 不存在 | 创建新会话 |
+| state.json 损坏 | 从文件重建 |
+| CLI 工具失败 | 回退到手动模式 |
+| 测试失败 | 循环回到 develop/debug |
+| >10 迭代 | 警告用户，建议拆分 |
+
+## Limitations
+
+1. **单会话限制**: 同一时间只能有一个活跃会话
+2. **迭代限制**: 建议不超过 10 次迭代
+3. **CLI 依赖**: 部分功能依赖 Gemini CLI 可用性
+4. **测试框架**: 需要 package.json 中定义测试脚本
+
+## Troubleshooting
+
+### Q: 如何查看当前会话状态？
+
+A: 在菜单中选择 "查看详情 (Status)"
+
+### Q: 如何恢复中断的会话？
+
+A: 使用 `--resume` 参数:
+```bash
+/ccw-loop --resume LOOP-xxx-2026-01-22
+```
+
+### Q: 如果 CLI 工具失败怎么办？
+
+A: Skill 会自动降级到手动模式，提示用户手动输入
+
+### Q: 如何添加自定义 action？
+
+A: 参见 [specs/action-catalog.md](specs/action-catalog.md) 的 "Action Extensions" 部分
+
+## Contributing
+
+添加新功能:
+1. 创建 action 文件在 `phases/actions/`
+2. 更新 orchestrator 决策逻辑
+3. 添加到 action-catalog.md
+4. 更新 action-menu.md

+└─────────────────────────────────────────────────────────────────┘
+```
+
+## Key Design Principles
+
+1. **统一状态**: API 和 Skill 共享 `.loop/{loopId}.json` 状态文件
+2. **控制信号**: Skill 每个 Action 前检查 status 字段 (paused/stopped)
+3. **文件驱动**: 所有进度、理解、结果都记录在 `.loop/{loopId}.progress/`
+4. **可恢复**: 任何时候可以继续之前的循环 (`--loop-id`)
+5. **双触发**: 支持 API 触发 (`--loop-id`) 和直接调用 (task description)
+6. **Gemini 辅助**: 使用 CLI 工具进行深度分析和假设验证
+
+## Execution Modes
+
+### Mode 1: Interactive (交互式)
+
+用户手动选择每个动作，适合复杂任务。
+
+```
+用户 → 选择动作 → 执行 → 查看结果 → 选择下一动作
+```
+
+### Mode 2: Auto-Loop (自动循环)
+
+按预设顺序自动执行，适合标准开发流程。
+
+```
+Develop → Debug → Validate → (如有问题) → Develop → ...
+```
+
+## Session Structure (Unified Location)
+
+```
+.loop/
+├── {loopId}.json              # 主状态文件 (API + Skill 共享)
+├── {loopId}.tasks.jsonl       # 任务列表 (API 管理)
+└── {loopId}.progress/         # Skill 进度文件
+    ├── develop.md             # 开发进度记录
+    ├── debug.md               # 理解演变文档

+    ├── changes.log            # 代码变更日志 (NDJSON)
+    └── debug.log              # 调试日志 (NDJSON)
+```
+
+## Directory Setup
+
+```javascript
+// loopId 来源:
+// 1. API 触发时: 从 --loop-id 参数获取
+// 2. 直接调用时: 生成新的 loop-v2-{timestamp}-{random}
+
+const loopId = args['--loop-id'] || generateLoopId()
+const loopFile = `.loop/${loopId}.json`
+const progressDir = `.loop/${loopId}.progress`
+
+// 创建进度目录
+Bash(`mkdir -p "${progressDir}"`)
+```
+
+## Action Catalog
+
+| Action | Purpose | Output Files | CLI Integration |
+|--------|---------|--------------|-----------------|

+## Integration with Loop Monitor (Dashboard)
+
+此 Skill 与 CCW Dashboard 的 Loop Monitor 实现 **控制平面 + 执行平面** 分离架构：
+
+### Control Plane (Dashboard/API → loop-v2-routes.ts)
+
+1. **创建循环**: `POST /api/loops/v2` → 创建 `.loop/{loopId}.json`
+2. **启动执行**: `POST /api/loops/v2/:loopId/start` → 触发 `/ccw-loop --loop-id {loopId} --auto`
+3. **暂停执行**: `POST /api/loops/v2/:loopId/pause` → 设置 `status='paused'` (Skill 下次检查时退出)
+4. **恢复执行**: `POST /api/loops/v2/:loopId/resume` → 设置 `status='running'` → 重新触发 Skill
+5. **停止执行**: `POST /api/loops/v2/:loopId/stop` → 设置 `status='failed'`
+
+### Execution Plane (ccw-loop Skill)
+
+1. **读取状态**: 从 `.loop/{loopId}.json` 读取 API 设置的状态
+2. **检查控制**: 每个 Action 前检查 `status` 字段
+3. **执行动作**: develop → debug → validate → complete
+4. **更新进度**: 写入 `.loop/{loopId}.progress/*.md` 和更新 `skill_state`
+5. **状态同步**: Dashboard 通过读取 `.loop/{loopId}.json` 获取进度
+
+## CLI Integration Points
+
+### Develop Phase
+```bash
+ccw cli -p "PURPOSE: Implement {task}...
+TASK: • Analyze requirements • Write code • Update progress
+MODE: write
+CONTEXT: @progress.md @tasks.json
+EXPECTED: Implementation + updated progress.md

+MODE: analysis
+CONTEXT: @understanding.md @debug.log
+EXPECTED: Hypotheses + instrumentation plan
+" --tool gemini --mode analysis --rule analysis-diagnose-bug-root-cause

+### Validate Phase
+```bash

+TASK: • Run tests • Check coverage • Verify requirements
+MODE: analysis
+CONTEXT: @validation.md @test-results.json
+EXPECTED: Validation report
+" --tool gemini --mode analysis --rule analysis-review-code-quality
+```
+
+## Error Handling
+
+| Situation | Action |
+|-----------|--------|
+| Session not found | Create new session |
+| State file corrupted | Rebuild from file contents |
+| CLI tool fails | Fallback to manual analysis |
+| Tests fail | Loop back to develop/debug |
+| >10 iterations | Warn user, suggest break |

+## Action Catalog
+
+| Action | Purpose | Preconditions | Effects |
+|--------|---------|---------------|---------|
+| [action-init](actions/action-init.md) | 初始化会话 | status=pending | initialized=true |
+| [action-menu](actions/action-menu.md) | 显示操作菜单 | initialized=true | 用户选择下一动作 |
+| [action-develop-with-file](actions/action-develop-with-file.md) | 开发任务 | initialized=true | 更新 progress.md |
+| [action-debug-with-file](actions/action-debug-with-file.md) | 假设调试 | initialized=true | 更新 understanding.md |
+| [action-validate-with-file](actions/action-validate-with-file.md) | 测试验证 | initialized=true | 更新 validation.md |
+| [action-complete](actions/action-complete.md) | 完成循环 | validation_passed=true | status=completed |
+
+## Termination Conditions
+
+1. **API 暂停**: `state.status === 'paused'` (Skill 退出，等待 resume)
+2. **API 停止**: `state.status === 'failed'` (Skill 终止)
+3. **任务完成**: `state.status === 'completed'`
+4. **迭代限制**: `state.current_iteration >= state.max_iterations`
+5. **Action 请求终止**: `actionResult.continue === false`
+
+## Error Recovery
+
+| Error Type | Recovery Strategy |
+|------------|-------------------|
+| 动作执行失败 | 记录错误，增加 error_count，继续下一动作 |
+| 状态文件损坏 | 从其他文件重建状态 (progress.md, understanding.md 等) |
+| 用户中止 | 保存当前状态，允许 --resume 恢复 |
+| CLI 工具失败 | 回退到手动分析模式 |
+
+## Mode Strategies
+
+### Interactive Mode (默认)
+
+每次显示菜单，让用户选择动作：
+
+```
+当前状态: 开发中
+可用操作:
+  1. 继续开发 (develop)
+  2. 开始调试 (debug)
+  3. 运行验证 (validate)
+  4. 查看进度 (status)
+  5. 退出 (exit)
+
+请选择:
+```
+
+### Auto Mode (自动循环)
+
+按预设流程自动执行：
+
+```
+Develop → Debug → Validate →
+  ↓ (如验证失败)
+Develop (修复) → Debug → Validate → 完成
+```
+
+## State Machine (API Status)
+
+```mermaid
+stateDiagram-v2
+    [*] --> created: API creates loop
+    created --> running: API /start → Trigger Skill
+    running --> paused: API /pause → Set status
+    running --> completed: action-complete
+    running --> failed: API /stop OR error
+    paused --> running: API /resume → Re-trigger Skill
+    completed --> [*]
+    failed --> [*]
+
+    note right of paused
+      Skill checks status before each action
+      If paused, Skill exits gracefully
+    end note
+
+    note right of running
+      Skill executes: init → develop → debug → validate
+    end note

+## 控制信号检查 (Control Signals)

+ */
+function checkControlSignals(loopId) {

+      // API 暂停了循环，Skill 应退出等待 resume
+      return { continue: false, action: 'pause_exit' }
+
+    case 'failed':
+      // API 停止了循环 (用户手动停止)
+      return { continue: false, action: 'stop_exit' }
+
+    case 'running':
+      // 正常继续
+      return { continue: true, action: 'continue' }
+
+    default:
+      // 异常状态
+      return { continue: false, action: 'stop_exit' }
+  }
+}
+```
+
+### 在 Action 中使用
+
+```markdown
+## Execution
+
+### Step 1: Check Control Signals
+
+\`\`\`javascript
+const control = checkControlSignals(loopId)
+if (!control.continue) {
+  // 输出退出原因
+  console.log(`Loop ${control.action}: status = ${state.status}`)
+
+  // 如果是 pause_exit，保存当前进度
+  if (control.action === 'pause_exit') {
+    updateSkillState(loopId, { current_action: 'paused' })
+  }
+
+  return  // 退出 Action
+}
+\`\`\`
+
+### Step 2: Execute Action Logic
+...
+```
+
+## 状态转换规则
+
+### 1. 初始化 (action-init)
+
+```javascript
+// Skill 初始化后
+{
+  // API 字段更新
+  status: 'created' → 'running',  // 或保持 'running' 如果 API 已设置
+  updated_at: timestamp,
+
+  // Skill 字段初始化
+  skill_state: {
+    current_action: 'init',
+    mode: 'auto',
+    develop: {
+      tasks: [...parsed_tasks],
+      total: N,
+      completed: 0
+    }
+  }
+}
+```
+
+### 2. 开发进行中 (action-develop-with-file)
+
+```javascript
+// 开发任务执行后
+{
+  updated_at: timestamp,
+  current_iteration: state.current_iteration + 1,
+
+  skill_state: {
+    current_action: 'develop',
+    last_action: 'action-develop-with-file',
+    completed_actions: [...state.skill_state.completed_actions, 'action-develop-with-file'],
+    develop: {
+      current_task: 'task-xxx',
+      completed: N+1,
+      last_progress_at: timestamp
+    }
+  }
+}
+```
+
+### 3. 调试进行中 (action-debug-with-file)
+
+```javascript
+// 调试执行后
+{
+  updated_at: timestamp,
+  current_iteration: state.current_iteration + 1,
+
+  skill_state: {
+    current_action: 'debug',
+    last_action: 'action-debug-with-file',
+    debug: {
+      active_bug: '...',
+      hypotheses_count: N,
+      hypotheses: [...new_hypotheses],
+      iteration: N+1,
+      last_analysis_at: timestamp
+    }
+  }
+}
+```
+
+### 4. 验证完成 (action-validate-with-file)
+
+```javascript
+// 验证执行后
+{
+  updated_at: timestamp,
+  current_iteration: state.current_iteration + 1,
+
+  skill_state: {
+    current_action: 'validate',
+    last_action: 'action-validate-with-file',
+    validate: {
+      test_results: [...results],
+      pass_rate: 95.5,
+      coverage: 85.0,
+      passed: true | false,
+      failed_tests: ['test1', 'test2'],
+      last_run_at: timestamp
+    }
+  }
+}
+```
+
+### 5. 完成 (action-complete)
+
+```javascript
+// 循环完成后
+{
+  status: 'running' → 'completed',
+  completed_at: timestamp,
+  updated_at: timestamp,
+
+  skill_state: {
+    current_action: 'complete',
+    last_action: 'action-complete'
+  }
+}
+```
+
+## 状态派生字段
+
+以下字段可从状态计算得出，不需要存储：
+
+```javascript
+// 开发完成度
+const developProgress = state.develop.total_count > 0
+  ? (state.develop.completed_count / state.develop.total_count) * 100
+  : 0
+
+// 是否有待开发任务
+const hasPendingDevelop = state.develop.tasks.some(t => t.status === 'pending')
+
+// 调试是否完成
+const debugCompleted = state.debug.confirmed_hypothesis !== null
+
+// 验证是否通过
+const validationPassed = state.validate.passed && state.validate.test_results.length > 0
+
+// 整体进度
+const overallProgress = (
+  (developProgress * 0.5) +
+  (debugCompleted ? 25 : 0) +
+  (validationPassed ? 25 : 0)
+)
+```
+
+## 文件同步
+
+### 统一位置 (Unified Location)
+
+状态与文件的对应关系：
+
+| 状态字段 | 同步文件 | 同步时机 |
+|----------|----------|----------|
+| 整个 LoopState | `.loop/{loopId}.json` | 每次状态变更 (主文件) |
+| `skill_state.develop` | `.loop/{loopId}.progress/develop.md` | 每次开发操作后 |
+| `skill_state.debug` | `.loop/{loopId}.progress/debug.md` | 每次调试操作后 |
+| `skill_state.validate` | `.loop/{loopId}.progress/validate.md` | 每次验证操作后 |
+| 代码变更日志 | `.loop/{loopId}.progress/changes.log` | 每次文件修改 (NDJSON) |
+| 调试日志 | `.loop/{loopId}.progress/debug.log` | 每次调试日志 (NDJSON) |
+
+### 文件结构示例
+
+```
+.loop/
+├── loop-v2-20260122-abc123.json         # 主状态文件 (API + Skill)
+├── loop-v2-20260122-abc123.tasks.jsonl  # 任务列表 (API 管理)
+└── loop-v2-20260122-abc123.progress/    # Skill 进度文件
+    ├── develop.md                       # 开发进度
+    ├── debug.md                         # 调试理解

+    └── debug.log                        # 调试日志 (NDJSON)
+```
+
+## 状态恢复
+
+如果主状态文件 `.loop/{loopId}.json` 损坏，可以从进度文件重建 skill_state:
+
+```javascript
+function rebuildSkillStateFromProgress(loopId) {
+  const progressDir = `.loop/${loopId}.progress`
+
+  // 尝试从进度文件解析状态
+  const skill_state = {
+    develop: parseProgressFile(`${progressDir}/develop.md`),
+    debug: parseProgressFile(`${progressDir}/debug.md`),
+    validate: parseProgressFile(`${progressDir}/validate.md`)
+  }
+
+  return skill_state
+}
+
+// 解析进度 Markdown 文件
+function parseProgressFile(filePath) {
+  const content = Read(filePath)
+  if (!content) return null
+
+  // 从 Markdown 表格和结构中提取数据
+  // ... implementation
+}
+```
+
+### 恢复策略
+
+1. **API 字段**: 无法恢复 - 需要从 API 重新获取或用户手动输入
+2. **skill_state 字段**: 可以从 `.progress/` 目录的 Markdown 文件解析
+3. **任务列表**: 从 `.loop/{loopId}.tasks.jsonl` 恢复
+
+## 状态验证
+
+```javascript
+function validateState(state) {
+  const errors = []
+
+  // 必需字段
+  if (!state.session_id) errors.push('Missing session_id')
+  if (!state.task_description) errors.push('Missing task_description')
+
+  // 状态一致性
+  if (state.initialized && state.status === 'pending') {
+    errors.push('Inconsistent: initialized but status is pending')
+  }
+
+  if (state.status === 'completed' && !state.validate.passed) {
+    errors.push('Inconsistent: completed but validation not passed')
+  }
+
+  // 开发任务一致性
+  const completedTasks = state.develop.tasks.filter(t => t.status === 'completed').length
+  if (completedTasks !== state.develop.completed_count) {
+    errors.push('Inconsistent: completed_count mismatch')
+  }
+
+  return { valid: errors.length === 0, errors }
+}

+```
+
+Only allow: `pending→running`, `running→completed/user_exit/failed`
+
+### 4. 错误限制约束
+
+- 最大错误次数: 3
+- 超过 3 次错误 → 自动终止
+- 每次错误 → 记录到 state.errors[]
+
+### 5. 迭代限制约束

+
+## Consolidation Rules
+
+更新 "Current Consolidated Understanding" 时遵循以下规则:
+
+1. **简化被否定项**: 移到 "What Was Disproven"，只保留单行摘要
+2. **保留有效见解**: 将确认的发现提升到 "What We Know"
+3. **避免重复**: 不在合并部分重复时间线细节
+4. **关注当前状态**: 描述现在知道什么，而不是过程
+5. **保留关键纠正**: 保留重要的 wrong→right 转换供学习
+
+## Anti-Patterns
+
+**错误示例 (冗余)**:
+```markdown
+## Current Consolidated Understanding
+
+In iteration 1 we thought X, but in iteration 2 we found Y, then in iteration 3...
+Also we checked A and found B, and then we checked C...
+```
+
+**正确示例 (精简)**:
+```markdown
+## Current Consolidated Understanding
+
+### What We Know
+- Error occurs during runtime update, not initialization
+- Config value is None (not missing key)
+
+### What Was Disproven
+- ~~Initialization error~~ (Timing evidence)
+- ~~Missing key hypothesis~~ (Key exists)
+
+### Current Investigation Focus
+Why is config value None during update?

+# Codex Debug-With-File Prompt
+
+## Overview
+
+Enhanced evidence-based debugging with **documented exploration process**. Records understanding evolution, consolidates insights, and uses analysis to correct misunderstandings.
+
+**Core workflow**: Explore → Document → Log → Analyze → Correct Understanding → Fix → Verify
+
+**Key enhancements over /prompts:debug**:
+- **understanding.md**: Timeline of exploration and learning
+- **Analysis-assisted correction**: Validates and corrects hypotheses
+- **Consolidation**: Simplifies proven-wrong understanding to avoid clutter
+- **Learning retention**: Preserves what was learned, even from failed attempts
+
+## Target Bug
+
+**$BUG**
+
+## Execution Process
+
+```
+Session Detection:
+   ├─ Check if debug session exists for this bug
+   ├─ EXISTS + understanding.md exists → Continue mode
+   └─ NOT_FOUND → Explore mode
+
+Explore Mode:
+   ├─ Locate error source in codebase
+   ├─ Document initial understanding in understanding.md
+   ├─ Generate testable hypotheses with analysis validation
+   ├─ Add NDJSON logging instrumentation
+   └─ Output: Hypothesis list + await user reproduction
+
+Analyze Mode:
+   ├─ Parse debug.log, validate each hypothesis
+   ├─ Use analysis to evaluate hypotheses and correct understanding
+   ├─ Update understanding.md with:
+   │   ├─ New evidence
+   │   ├─ Corrected misunderstandings (strikethrough + correction)
+   │   └─ Consolidated current understanding
+   └─ Decision:
+       ├─ Confirmed → Fix root cause
+       ├─ Inconclusive → Add more logging, iterate
+       └─ All rejected → Assisted new hypotheses
+
+Fix & Cleanup:
+   ├─ Apply fix based on confirmed hypothesis
+   ├─ User verifies
+   ├─ Document final understanding + lessons learned
+   ├─ Remove debug instrumentation
+   └─ If not fixed → Return to Analyze mode
+```
+
+## Implementation Details
+
+### Session Setup & Mode Detection
+
+```javascript
+const getUtc8ISOString = () => new Date(Date.now() + 8 * 60 * 60 * 1000).toISOString()
+
+const bugSlug = "$BUG".toLowerCase().replace(/[^a-z0-9]+/g, '-').substring(0, 30)
+const dateStr = getUtc8ISOString().substring(0, 10)
+
+const sessionId = `DBG-${bugSlug}-${dateStr}`
+const sessionFolder = `.workflow/.debug/${sessionId}`
+const debugLogPath = `${sessionFolder}/debug.log`
+const understandingPath = `${sessionFolder}/understanding.md`
+const hypothesesPath = `${sessionFolder}/hypotheses.json`
+
+// Auto-detect mode
+const sessionExists = fs.existsSync(sessionFolder)
+const hasUnderstanding = sessionExists && fs.existsSync(understandingPath)
+const logHasContent = sessionExists && fs.existsSync(debugLogPath) && fs.statSync(debugLogPath).size > 0
+
+const mode = logHasContent ? 'analyze' : (hasUnderstanding ? 'continue' : 'explore')
+
+if (!sessionExists) {
+  bash(`mkdir -p ${sessionFolder}`)
+}
+```
+
+### Explore Mode
+
+#### Step 1.1: Locate Error Source
+
+```javascript
+// Extract keywords from bug description
+const keywords = extractErrorKeywords("$BUG")
+
+// Search codebase for error locations
+const searchResults = []
+for (const keyword of keywords) {
+  const results = Grep({ pattern: keyword, path: ".", output_mode: "content", "-C": 3 })
+  searchResults.push({ keyword, results })
+}
+
+// Identify affected files and functions
+const affectedLocations = analyzeSearchResults(searchResults)
+```
+
+#### Step 1.2: Document Initial Understanding
+
+Create `understanding.md`:
+
+```markdown
+# Understanding Document
+
+**Session ID**: ${sessionId}
+**Bug Description**: $BUG
+**Started**: ${getUtc8ISOString()}
+
+---
+
+## Exploration Timeline
+
+### Iteration 1 - Initial Exploration (${timestamp})
+
+#### Current Understanding
+
+Based on bug description and initial code search:
+
+- Error pattern: ${errorPattern}
+- Affected areas: ${affectedLocations.map(l => l.file).join(', ')}
+- Initial hypothesis: ${initialThoughts}
+
+#### Evidence from Code Search
+
+${searchResults.map(r => `
+**Keyword: "${r.keyword}"**
+- Found in: ${r.results.files.join(', ')}
+- Key findings: ${r.insights}
+`).join('\n')}
+
+#### Next Steps
+
+- Generate testable hypotheses
+- Add instrumentation
+- Await reproduction
+
+---
+
+## Current Consolidated Understanding
+
+${initialConsolidatedUnderstanding}
+```
+
+#### Step 1.3: Generate Hypotheses
+
+Analyze the bug and generate 3-5 testable hypotheses:
+
+```javascript
+// Hypothesis generation based on error pattern
+const HYPOTHESIS_PATTERNS = {
+  "not found|missing|undefined|未找到": "data_mismatch",
+  "0|empty|zero|registered": "logic_error",
+  "timeout|connection|sync": "integration_issue",
+  "type|format|parse": "type_mismatch"
+}
+
+function generateHypotheses(bugDescription, affectedLocations) {
+  // Generate targeted hypotheses based on error analysis
+  // Each hypothesis includes:
+  // - id: H1, H2, ...
+  // - description: What might be wrong
+  // - testable_condition: What to log
+  // - logging_point: Where to add instrumentation
+  // - evidence_criteria: What confirms/rejects it
+  return hypotheses
+}
+```
+
+Save to `hypotheses.json`:
+
+```json
+{
+  "iteration": 1,
+  "timestamp": "2025-01-21T10:00:00+08:00",
+  "hypotheses": [
+    {
+      "id": "H1",
+      "description": "Data structure mismatch - expected key not present",
+      "testable_condition": "Check if target key exists in dict",
+      "logging_point": "file.py:func:42",
+      "evidence_criteria": {
+        "confirm": "data shows missing key",
+        "reject": "key exists with valid value"
+      },
+      "likelihood": 1,
+      "status": "pending"
+    }
+  ]
+}
+```
+
+#### Step 1.4: Add NDJSON Instrumentation
+
+For each hypothesis, add logging at the specified location:
+
+**Python template**:
+```python
+# region debug [H{n}]
+try:
+    import json, time
+    _dbg = {
+        "sid": "{sessionId}",
+        "hid": "H{n}",
+        "loc": "{file}:{line}",
+        "msg": "{testable_condition}",
+        "data": {
+            # Capture relevant values here
+        },
+        "ts": int(time.time() * 1000)
+    }
+    with open(r"{debugLogPath}", "a", encoding="utf-8") as _f:
+        _f.write(json.dumps(_dbg, ensure_ascii=False) + "\n")
+except: pass
+# endregion
+```
+
+**JavaScript/TypeScript template**:
+```javascript
+// region debug [H{n}]
+try {
+  require('fs').appendFileSync("{debugLogPath}", JSON.stringify({
+    sid: "{sessionId}",
+    hid: "H{n}",
+    loc: "{file}:{line}",
+    msg: "{testable_condition}",
+    data: { /* Capture relevant values */ },
+    ts: Date.now()
+  }) + "\n");
+} catch(_) {}
+// endregion
+```
+
+#### Step 1.5: Output to User
+
+```
+## Hypotheses Generated
+
+Based on error "$BUG", generated {n} hypotheses:
+
+{hypotheses.map(h => `
+### ${h.id}: ${h.description}
+- Logging at: ${h.logging_point}
+- Testing: ${h.testable_condition}
+- Evidence to confirm: ${h.evidence_criteria.confirm}
+- Evidence to reject: ${h.evidence_criteria.reject}
+`).join('')}
+
+**Debug log**: ${debugLogPath}
+
+**Next**: Run reproduction steps, then come back for analysis.
+```
+
+### Analyze Mode
+
+#### Step 2.1: Parse Debug Log
+
+```javascript
+// Parse NDJSON log
+const entries = Read(debugLogPath).split('\n')
+  .filter(l => l.trim())
+  .map(l => JSON.parse(l))
+
+// Group by hypothesis
+const byHypothesis = groupBy(entries, 'hid')
+
+// Validate each hypothesis
+for (const [hid, logs] of Object.entries(byHypothesis)) {
+  const hypothesis = hypotheses.find(h => h.id === hid)
+  const latestLog = logs[logs.length - 1]
+
+  // Check if evidence confirms or rejects hypothesis
+  const verdict = evaluateEvidence(hypothesis, latestLog.data)
+  // Returns: 'confirmed' | 'rejected' | 'inconclusive'
+}
+```
+
+#### Step 2.2: Analyze Evidence and Correct Understanding
+
+Review the debug log and evaluate each hypothesis:
+
+1. Parse all log entries
+2. Group by hypothesis ID
+3. Compare evidence against expected criteria
+4. Determine verdict: confirmed | rejected | inconclusive
+5. Identify incorrect assumptions from previous understanding
+6. Generate corrections
+
+#### Step 2.3: Update Understanding with Corrections
+
+Append new iteration to `understanding.md`:
+
+```markdown
+### Iteration ${n} - Evidence Analysis (${timestamp})
+
+#### Log Analysis Results
+
+${results.map(r => `
+**${r.id}**: ${r.verdict.toUpperCase()}
+- Evidence: ${JSON.stringify(r.evidence)}
+- Reasoning: ${r.reason}
+`).join('\n')}
+
+#### Corrected Understanding
+
+Previous misunderstandings identified and corrected:
+
+${corrections.map(c => `
+- ~~${c.wrong}~~ → ${c.corrected}
+  - Why wrong: ${c.reason}
+  - Evidence: ${c.evidence}
+`).join('\n')}
+
+#### New Insights
+
+${newInsights.join('\n- ')}
+
+${confirmedHypothesis ? `
+#### Root Cause Identified
+
+**${confirmedHypothesis.id}**: ${confirmedHypothesis.description}
+
+Evidence supporting this conclusion:
+${confirmedHypothesis.supportingEvidence}
+` : `
+#### Next Steps
+
+${nextSteps}
+`}
+
+---
+
+## Current Consolidated Understanding (Updated)
+
+${consolidatedUnderstanding}
+```
+
+#### Step 2.4: Update hypotheses.json
+
+```json
+{
+  "iteration": 2,
+  "timestamp": "2025-01-21T10:15:00+08:00",
+  "hypotheses": [
+    {
+      "id": "H1",
+      "status": "rejected",
+      "verdict_reason": "Evidence shows key exists with valid value",
+      "evidence": {...}
+    },
+    {
+      "id": "H2",
+      "status": "confirmed",
+      "verdict_reason": "Log data confirms timing issue",
+      "evidence": {...}
+    }
+  ],
+  "corrections": [
+    {
+      "wrong_assumption": "...",
+      "corrected_to": "...",
+      "reason": "..."
+    }
+  ]
+}
+```
+
+### Fix & Verification
+
+#### Step 3.1: Apply Fix
+
+Based on confirmed hypothesis, implement the fix in the affected files.
+
+#### Step 3.2: Document Resolution
+
+Append to `understanding.md`:
+
+```markdown
+### Iteration ${n} - Resolution (${timestamp})
+
+#### Fix Applied
+
+- Modified files: ${modifiedFiles.join(', ')}
+- Fix description: ${fixDescription}
+- Root cause addressed: ${rootCause}
+
+#### Verification Results
+
+${verificationResults}
+
+#### Lessons Learned
+
+What we learned from this debugging session:
+
+1. ${lesson1}
+2. ${lesson2}
+3. ${lesson3}
+
+#### Key Insights for Future
+
+- ${insight1}
+- ${insight2}
+```
+
+#### Step 3.3: Cleanup
+
+Remove debug instrumentation by searching for region markers:
+
+```javascript
+const instrumentedFiles = Grep({
+  pattern: "# region debug|// region debug",
+  output_mode: "files_with_matches"
+})
+
+for (const file of instrumentedFiles) {
+  // Remove content between region markers
+  removeDebugRegions(file)
+}
+```
+

+| `data` | Captured values |
+| `ts` | Timestamp (ms) |
+
+## Iteration Flow
+
+```
+First Call (/prompts:debug-with-file BUG="error"):
+   ├─ No session exists → Explore mode
+   ├─ Extract error keywords, search codebase
+   ├─ Document initial understanding in understanding.md
+   ├─ Generate hypotheses
+   ├─ Add logging instrumentation
+   └─ Await user reproduction
+
+After Reproduction (/prompts:debug-with-file BUG="error"):
+   ├─ Session exists + debug.log has content → Analyze mode
+   ├─ Parse log, evaluate hypotheses
+   ├─ Update understanding.md with:
+   │   ├─ Evidence analysis results
+   │   ├─ Corrected misunderstandings (strikethrough)
+   │   ├─ New insights
+   │   └─ Updated consolidated understanding
+   ├─ Update hypotheses.json with verdicts
+   └─ Decision:
+       ├─ Confirmed → Fix → Document resolution
+       ├─ Inconclusive → Add logging, document next steps
+       └─ All rejected → Assisted new hypotheses
+
+Output:
+   ├─ .workflow/.debug/DBG-{slug}-{date}/debug.log
+   ├─ .workflow/.debug/DBG-{slug}-{date}/understanding.md (evolving document)
+   └─ .workflow/.debug/DBG-{slug}-{date}/hypotheses.json (history)
+```
+
+## Error Handling
+
+| Situation | Action |
+|-----------|--------|
+| Empty debug.log | Verify reproduction triggered the code path |
+| All hypotheses rejected | Generate new hypotheses based on disproven assumptions |
+| Fix doesn't work | Document failed fix attempt, iterate with refined understanding |
+| >5 iterations | Review consolidated understanding, escalate with full context |
+| Understanding too long | Consolidate aggressively, archive old iterations to separate file |
+
+## Consolidation Rules
+
+When updating "Current Consolidated Understanding":
+
+1. **Simplify disproven items**: Move to "What Was Disproven" with single-line summary
+2. **Keep valid insights**: Promote confirmed findings to "What We Know"
+3. **Avoid duplication**: Don't repeat timeline details in consolidated section
+4. **Focus on current state**: What do we know NOW, not the journey
+5. **Preserve key corrections**: Keep important wrong→right transformations for learning
+
+**Bad (cluttered)**:
+```markdown
+## Current Consolidated Understanding
+
+In iteration 1 we thought X, but in iteration 2 we found Y, then in iteration 3...
+Also we checked A and found B, and then we checked C...
+```
+
+**Good (consolidated)**:
+```markdown
+## Current Consolidated Understanding
+
+### What We Know
+- Error occurs during runtime update, not initialization
+- Config value is None (not missing key)
+
+### What Was Disproven
+- ~~Initialization error~~ (Timing evidence)
+- ~~Missing key hypothesis~~ (Key exists)
+
+### Current Investigation Focus
+Why is config value None during update?
+```
+
+## Comparison with /prompts:debug

+|---------|-----------------|---------------------------|
+| NDJSON logging | ✅ | ✅ |
+| Hypothesis generation | Manual | Analysis-assisted |
+| Exploration documentation | ❌ | ✅ understanding.md |
+| Understanding evolution | ❌ | ✅ Timeline + corrections |
+| Error correction | ❌ | ✅ Strikethrough + reasoning |
+| Consolidated learning | ❌ | ✅ Current understanding section |
+| Hypothesis history | ❌ | ✅ hypotheses.json |
+| Analysis validation | ❌ | ✅ At key decision points |

+## 问题描述
+
+用户在使用 `ccw view` 界面安装 CodexLens 时遇到错误：
+
+```
+Error: Failed to install codexlens: Using Python 3.12.3 environment at: .codexlens/venv
+× No solution found when resolving dependencies:
+╰─▶ Because there are no versions of codexlens[semantic] and you require codexlens[semantic], we can conclude that your requirements are unsatisfiable.
+```
+
+## 根本原因
+
+1. **包名不一致**：pyproject.toml 中定义的包名是 `codex-lens`（带连字符），但代码中尝试安装 `codexlens`（没有连字符）
+2. **包未发布到 PyPI**：`codex-lens` 是本地开发包，没有发布到 PyPI，只能通过本地路径安装
+3. **本地路径查找逻辑问题**：`findLocalPackagePath()` 函数在非开发环境（从 node_modules 运行）时会提前返回 null，导致找不到本地路径
+
+## 修复内容
+
+### 1. 核心文件修复 (ccw/src/tools/codex-lens.ts)
+
+#### 1.1 修改 `findLocalPackagePath()` 函数
+- **移除** `isDevEnvironment()` 早期返回逻辑
+- **添加** 更多本地路径搜索位置（包括父目录）
+- **总是** 尝试查找本地路径，即使从 node_modules 运行
+
+#### 1.2 修改 `bootstrapWithUv()` 函数
+- **移除** PyPI 安装的 fallback 逻辑
+- **改为** 找不到本地路径时直接返回错误，提供清晰的修复指导
+
+#### 1.3 修改 `installSemanticWithUv()` 函数
+- **移除** PyPI 安装的 fallback 逻辑
+- **改为** 找不到本地路径时直接返回错误
+
+#### 1.4 修改 `bootstrapVenv()` 函数（pip fallback）
+- **移除** PyPI 安装的 fallback 逻辑
+- **改为** 找不到本地路径时抛出错误
+
+#### 1.5 修复包名引用
+- 将所有 `codexlens` 更改为 `codex-lens`（3 处）
+
+### 2. 文档和脚本修复
+
+修复以下文件中的包名引用（`codexlens` → `codex-lens`）：
+
+- ✅ `ccw/scripts/memory_embedder.py`
+- ✅ `ccw/scripts/README-memory-embedder.md`
+- ✅ `ccw/scripts/QUICK-REFERENCE.md`
+- ✅ `ccw/scripts/IMPLEMENTATION-SUMMARY.md`
+
+## 修复后的行为
+
+### 安装流程
+
+1. **查找本地路径**：
+   - 检查 `process.cwd()/codex-lens`
+   - 检查 `__dirname/../../../codex-lens`（项目根目录）
+   - 检查 `homedir()/codex-lens`
+   - 检查 `parent(cwd)/codex-lens`（新增）
+
+2. **本地安装**（找到路径）：
+   ```bash
+   uv pip install -e /path/to/codex-lens[semantic]
+   ```
+
+3. **失败并提示**（找不到路径）：
+   ```
+   Cannot find codex-lens directory for local installation.
+
+   codex-lens is a local development package (not published to PyPI) and must be installed from local files.
+
+   To fix this:
+   1. Ensure the 'codex-lens' directory exists in your project root
+   2. Verify pyproject.toml exists in codex-lens directory
+   3. Run ccw from the correct working directory
+   4. Or manually install: cd codex-lens && pip install -e .[semantic]
+   ```
+
+## 验证步骤
+
+1. 确认 `codex-lens` 目录存在于项目根目录
+2. 确认 `codex-lens/pyproject.toml` 存在
+3. 从项目根目录运行 ccw
+4. 尝试安装 CodexLens semantic 依赖
+
+## 正确的手动安装方式
+
+```bash
+# 从项目根目录
+cd D:\Claude_dms3\codex-lens
+pip install -e .[semantic]
+
+# 或者使用绝对路径
+pip install -e D:\Claude_dms3\codex-lens[semantic]
+
+# GPU 加速（CUDA）
+pip install -e .[semantic-gpu]
+
+# GPU 加速（DirectML，Windows）
+pip install -e .[semantic-directml]
+```
+
+## 注意事项
+
+- **不要** 使用 `pip install codex-lens[semantic]`（会失败，包未发布到 PyPI）
+- **必须** 使用 `-e` 参数进行 editable 安装
+- **必须** 从正确的工作目录运行（包含 codex-lens 目录的目录）
+
+## 影响范围
+
+- ✅ ccw view 界面安装
+- ✅ 命令行 UV 安装
+- ✅ 命令行 pip fallback 安装
+- ✅ 文档和脚本中的安装说明
+
+## 测试建议
+
+1. 从全局安装的 ccw 运行（npm install -g）
+2. 从本地开发目录运行（npm link）
+3. 从不同的工作目录运行
+4. 测试所有三种 GPU 模式（cpu, cuda, directml）
