majiayu000 CCW Loop - Stateless Iterative Development Workflow
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。
Arguments
| Arg | Required | Description |
|---|---|---|
| task | No | Task description (for new loop, mutually exclusive with --loop-id) |
| --loop-id | No | Existing loop ID to continue (from API or previous session) |
| --auto | No | Auto-cycle mode (develop → debug → validate → complete) |

Key Design Principles
- 统一状态: API 和 Skill 共享
.loop/{loopId}.json状态文件 - 控制信号: Skill 每个 Action 前检查 status 字段 (paused/stopped)
- 文件驱动: 所有进度、理解、结果都记录在
.loop/{loopId}.progress/ - 可恢复: 任何时候可以继续之前的循环 (
--loop-id) - 双触发: 支持 API 触发 (
--loop-id) 和直接调用 (task description) - 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
├── validate.md # 验证报告
├── changes.log # 代码变更日志 (NDJSON)
└── debug.log # 调试日志 (NDJSON)
Directory Setup
// 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 |
|---|---|---|---|
| action-init | 初始化循环会话 | meta.json, state.json | - |
| action-develop-with-file | 开发任务执行 | progress.md, tasks.json | gemini --mode write |
| action-debug-with-file | 假设驱动调试 | understanding.md, hypotheses.json | gemini --mode analysis |
| action-validate-with-file | 测试与验证 | validation.md, test-results.json | gemini --mode analysis |
| action-complete | 完成循环 | summary.md | - |
| action-menu | 显示操作菜单 | - | - |
Usage
# 启动新循环 (直接调用)
/ccw-loop "实现用户认证功能"
# 继续现有循环 (API 触发或手动恢复)
/ccw-loop --loop-id loop-v2-20260122-abc123
# 自动循环模式
/ccw-loop --auto "修复登录bug并添加测试"
# API 触发自动循环
/ccw-loop --loop-id loop-v2-20260122-abc123 --auto
Execution Flow
┌─────────────────────────────────────────────────────────────────┐
│ /ccw-loop [<task> | --loop-id <id>] [--auto] │
├─────────────────────────────────────────────────────────────────┤
│ │
│ 1. Parameter Detection: │
│ ├─ IF --loop-id provided: │
│ │ ├─ Read .loop/{loopId}.json │
│ │ ├─ Validate status === 'running' │
│ │ └─ Continue from skill_state.current_action │
│ └─ ELSE (task description): │
│ ├─ Generate new loopId │
│ ├─ Create .loop/{loopId}.json │
│ └─ Initialize with action-init │
│ │
│ 2. Orchestrator Loop: │
│ ├─ Read state from .loop/{loopId}.json │
│ ├─ Check control signals: │
│ │ ├─ status === 'paused' → Exit (wait for resume) │
│ │ ├─ status === 'failed' → Exit with error │
│ │ └─ status === 'running' → Continue │
│ ├─ Show menu / auto-select next action │
│ ├─ Execute action │
│ ├─ Update .loop/{loopId}.progress/{action}.md │
│ ├─ Update .loop/{loopId}.json (skill_state) │
│ └─ Loop or exit based on user choice / completion │
│ │
│ 3. Action Execution: │
│ ├─ BEFORE: checkControlSignals() → exit if paused/stopped │
│ ├─ Develop: Plan → Implement → Document progress │
│ ├─ Debug: Hypothesize → Instrument → Analyze → Fix │
│ ├─ Validate: Test → Check → Report │
│ └─ AFTER: Update skill_state in .loop/{loopId}.json │
│ │
│ 4. Termination: │
│ ├─ Control signal: paused (graceful exit, wait resume) │
│ ├─ Control signal: stopped (failed state) │
│ ├─ User exits (interactive mode) │
│ ├─ All tasks completed (status → completed) │
│ └─ Max iterations reached │

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)
- 创建循环:
POST /api/loops/v2→ 创建.loop/{loopId}.json - 启动执行:
POST /api/loops/v2/:loopId/start→ 触发/ccw-loop --loop-id {loopId} --auto - 暂停执行:
POST /api/loops/v2/:loopId/pause→ 设置status='paused'(Skill 下次检查时退出) - 恢复执行:
POST /api/loops/v2/:loopId/resume→ 设置status='running'→ 重新触发 Skill - 停止执行:
POST /api/loops/v2/:loopId/stop→ 设置status='failed'
Execution Plane (ccw-loop Skill)
- 读取状态: 从
.loop/{loopId}.json读取 API 设置的状态 - 检查控制: 每个 Action 前检查
status字段 - 执行动作: develop → debug → validate → complete
- 更新进度: 写入
.loop/{loopId}.progress/*.md和更新skill_state - 状态同步: Dashboard 通过读取
.loop/{loopId}.json获取进度
CLI Integration Points
Develop Phase
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

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 |
Post-Completion Expansion
完成后询问用户是否扩展为 issue (test/enhance/refactor/doc)，选中项调用 /issue:new "{summary} - {dimension}"
