## 🔄 Ralph 执行循环(简化版)
不使用 Claude Code 的情况下,可通过 OpenClaw sub-agent 模拟:
```
每次循环:
1. 读取 prd.json
2. 选取 id 最小的 passes:false 的 story
3. 生成 fresh sub-session 执行该 story
4. 运行 quality gate 检查
5. 通过 → passes:true,追加 notes
6. 重复直到全部完成
```

## 📝 progress.txt 格式

[YYYY-MM-DD HH:mm] Story #N 完成:

## 💡 与编程任务 PRD 的核心区别
| 维度 | 编程任务 PRD | 非编程任务 PRD |
|------|------------|--------------|
| 工具链 | git, npm, typecheck, test | FFmpeg, 爬虫, LLM |
| 质量门 | 自动(CI/CD) | 混合(自动+人工) |
| 人工介入 | 极低(代码审查) | 中等(创意审核) |
| Story 大小 | 极小(单次完成) | 中等(可包含创意工作) |
| 迭代速度 | 快(机器执行) | 慢(人机混合) |

## 🦞 OpenClaw Native Ralph 架构(2026-04-11 实测验证)
### 核心发现
| 问题 | 结论 |
|------|------|
| Ubuntu1 上无 skill(0个) | Skill 密集型任务 → MacMini;系统任务 → Ubuntu1 |
| sessions_spawn + node 参数 | ✅ 可跨节点派生子 agent |
| prd.json 状态机 | ✅ 落地验证通过 |
| progress.txt 追加日志 | ✅ 追加验证通过 |
| Gateway REST API | ❌ 未开启,改用 sessions_spawn |
### 架构图
```
星枢(MacMini / 主会话)
└── Ralph Engine(Python 脚本 / 星枢派生子 agent)
│
├── 读取 prd.json
├── 选取 passes:false 的 story
├── 判断 targetNode:skill密集型 → MacMini / 系统任务 → Ubuntu1
├── sessions_spawn(mode=run, node=目标节点)
│ └── 子 agent 执行 story + quality gate
├── 更新 prd.json (passes:true / notes)
├── 追加 progress.txt
└── 循环直到全部完成 → Telegram 通知
```
### 节点 Skill 地图
| 节点 | Skill 可用性 | 适合任务类型 |
|------|------------|------------|
| MacMini (192.168.3.189) | 全部(Last30Days, n8n, OpenCode, image_generate 等) | 研究、内容生产、编码 |
| Ubuntu1 (192.168.3.47) | 无 | 系统运维、Docker、巡检 |
| Ubuntu2 (192.168.3.45) | 部分 | n8n 工作流、中间层处理 |
### sessions_spawn 调用格式(OpenClaw Native)
```python
# Ralph Engine 内核心调用
sessions_spawn(
task=f"""你是 {node} 上的执行者。执行以下 story:
Story: {story_title}
Quality Gate: {qg_type} - {qg_desc}
工作目录: {work_dir}
目标文件: {target_path}
步骤:
1. [执行命令]
2. [quality gate 验证]
3. [落地 marker 文件或输出]
""",
runtime="subagent",
mode="run",
node="ubuntu1 | (default MacMini)",
runTimeoutSeconds=600,
label=f"ralph-story-{story_id}"
)
```
### Quality Gate 落地标准(实测有效)
```python
# ✅ 有效类型
"type": "file-exists" # touch marker 文件
"type": "command-output" # 命令退出码 0
"type": "human-review" # 人工确认(不可省)
# ⚠️ 限制
# - Last30Days 等 skill 必须确认目标节点有装
# - human-review 类型需要人工发送确认指令
```

## ⏰ 自主循环触发设计
### 方式一:Cron 触发(定时拉起 Ralph Engine)
```bash
# MacMini crontab
0 2 * * * openclaw agent --task "检查 ~/ralph-queue/ 目录,有 prd.json 则启动 Ralph Engine" --agent xingshu
```
### 方式二:目录监听(文件触发)
```bash
# inotifywait 或 launchd WatchPath
# 检测到 ~/ralph-queue/*.json → 自动启动 Ralph Engine
```
### 方式三:用户指令触发(最简单)
```
比利哥:开始执行 ralph prd.json
星枢 → 派生子 agent → 启动 Engine
```

## ✅ 实测验证记录(2026-04-11)
### 测试:Ubuntu1 系统巡检
- **结果**:3/3 stories ✅ 完成
- **落地文件**:`sysinfo.txt`(1116B), `docker_status.txt`(835B), `audit_report.md`(2347B), `prd.json`(345B ✅ passes:true), `progress.txt`(188B ✅ 3条追加)
- **耗时**:1分43秒
### 关键验证点
| 验证项 | 结果 |
|--------|------|
| prd.json passes:true 更新 | ✅ 成功 |
| progress.txt 追加日志 | ✅ 成功 |
| 跨节点 sessions_spawn | ✅ Ubuntu1 正常 |
| skill 路径(Last30Days) | ⚠️ Ubuntu1 无 skill,改用模拟 |
| 文件落地 | ✅ 实际验证 |
### 架构修正(对比原设计)
1. **Python Ralph Engine 无法直接调用 sessions API** → 改用 "Ralph Engine as sub-agent task"
2. **skill 全在 MacMini** → 任务智能路由:系统任务→Ubuntu1/内容生产→MacMini
3. **Gateway REST API 限制** → sessions_spawn 是运行时工具,非 API
### 最终架构(已验证)
```
