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

Shared Configuration

Item	Path
Working directory	.claude/ralph-ryan/
PRD 子目录	.claude/ralph-ryan/<prd-slug>/
PRD markdown	.claude/ralph-ryan/<prd-slug>/prd.md
PRD JSON	.claude/ralph-ryan/<prd-slug>/prd.json
Progress log	.claude/ralph-ryan/<prd-slug>/progress.txt
Loop state	.claude/ralph-ryan/<prd-slug>/ralph-loop.local.md
Archived runs	.claude/ralph-ryan-archived/<date>-<prd-slug>/

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

# 查看所有 PRD 状态
/ralph-ryan:status

# 创建新 PRD (会询问 slug 名称)
/ralph-ryan:prd [describe your feature]

# 准备执行 (会列出可选 PRD)
/ralph-ryan:prep

# 执行 (会列出可选 PRD，自动循环直到完成)
/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：

1. 精准 commit（只提交相关文件）
2. 冲突检测（多 PRD 修改同一文件时预警）
