Run the autonomous loop to execute features from `prds/` directory.
## Usage
```
/ralph # Run next available project (respects dependencies)
/ralph 25 # Run with 25 iterations
/ralph auth-flow # Run specific project
```
## Process
Run the loop script in background mode:
```bash
~/.claude/skills/ralph/ralph.sh [iterations] [project-name]
```
Use `run_in_background: true` to prevent timeout. After starting, tell the user to check progress with `tail -f <worktree>/.ralph-progress.txt`.
### What It Does
1. Shows dependency graph, finds next available project
2. Creates git worktree at `../{repo}-{feature}/`
3. For each iteration:
- Picks first story where `passes: false`
- Implements it, runs quality checks
- Commits: `feat: [id] - [title]`
- Updates JSON, syncs back to main repo
4. When all stories pass, outputs `<promise>COMPLETE</promise>`
### Dependencies
Ralph reads `dependsOn` from each PRD and enforces ordering:
```json
{
"projectName": "Dashboard",
"dependsOn": ["auth-flow", "user-profile"]
}
```
Projects with incomplete dependencies are blocked. Ralph picks the first ready project alphabetically.
## Prerequisites
1. At least one `.json` PRD file in `.claude/plans/`, `plans/`, or `prds/`
2. Use plan mode to create a plan, then run `/ralph-json-create-issues` to convert it
## Notes
- Run multiple Ralphs in parallel on independent projects (separate terminals)
- Each works in its own worktree, no conflicts
