Ralph Agent
Autonomous coding agent that implements user stories iteratively with multi-PRD parallel development support.
Routing
Based on user intent, load the corresponding instruction file:
| Intent | Keywords | Action |
|---|
| PRD | prd, create, generate, plan | Read {baseDir}/prd.md |
| Prep | prep, prepare, convert, setup | Read {baseDir}/prep.md |
| Run | run, execute, go, start | Read {baseDir}/run.md |
| Status | status, list, overview | Read {baseDir}/status.md |

prd.json Branch Fields
| Field | Description |
|---|
branchName | Target branch for execution |
baseBranch | Base branch for creation (only if creating new branch) |
Branch strategy (set during prep):
- Use current:
branchName = current branch, no baseBranch
- New from current:
branchName = ralph/<prd-slug>, baseBranch = current branch
- New from main:
branchName = ralph/<prd-slug>, baseBranch = main
Quick Reference
/ralph-ryan:status
/ralph-ryan:prd [describe your feature]
/ralph-ryan:prep
/ralph-ryan:run [prd-slug] [--max-iterations N]
停止循环：直接 Ctrl+C 终止即可。
Session Isolation
每个循环状态文件 (ralph-loop.local.md) 包含 session_hash 字段。Stop Hook 在第一次迭代时自动填入当前会话 transcript 路径的 SHA256 哈希值（16字符），确保：
- 只有启动循环的会话才能继续它
- 其他会话不会干扰正在运行的循环
- 隐私保护：不存储完整路径，只存储哈希值
- 如果其他会话尝试退出时发现有活跃循环，会提示选择：退出或接管
File Tracking
每个 story 完成后，在 prd.json 中记录修改的文件：
{
"id": "US-003",
"passes": true,
"filesChanged": [
"app/risk/greeks/page.tsx",
"components/charts/greeks-heatmap.tsx"
]
}
用于：
- 精准 commit（只提交相关文件）
- 冲突检测（多 PRD 修改同一文件时预警）
