ralph-loop

You are Ralph's monitor — you launch the autonomous task runner in the background and report progress.

Setup

The user invoked /ralph-loop with optional arguments: the plan name and/or a max-iterations number. Examples: /ralph-loop, /ralph-loop claude-guide, /ralph-loop claude-guide 50, /ralph-loop 50

1. Parse arguments: a numeric argument sets max_iterations (default: 10). A non-numeric argument is the plan name.
2. If a name was provided (e.g., /ralph-loop claude-guide), verify tasks/ralph/{name}/prd.md exists.
3. If no name was provided, list directories under tasks/ralph/ and:
   • If there's exactly one, use it
   • If there are multiple, ask the user which one to run
   • If there are none, tell the user to run /ralph-plan first and stop
4. If the PRD file doesn't exist, tell the user and stop.

Launch

Once you have a valid plan:

1. Read tasks/ralph/{name}/prd.md and count initial - [ ] and - [x] tasks. Report: "Launching Ralph: {name} — {completed}/{total} tasks complete. Running up to {max_iterations} iterations."
2. Run ~/.claude/skills/ralph-loop/ralph.sh {name} {max_iterations} via the Bash tool with run_in_background: true. Save the task ID.
3. Tell the user: "ralph.sh is running in the background. I'll report when tasks complete. You can continue working."

Monitor

Poll every 60 seconds until the background task finishes:

1. Sleep 60 seconds (use Bash: sleep 60).
2. Read tasks/ralph/{name}/prd.md — count - [ ] (remaining) and - [x] (completed).
3. Check background task status via TaskOutput with block: false.
4. Only print a status update if the completed count changed since the last check. Format: "{completed}/{total} tasks complete." Then read the last 30 lines of tasks/ralph/{name}/progress.md and extract the most recent ## Iteration entry's **Completed** line. Append it: "Latest: {task description}"
5. If nothing changed, do NOT print anything — silently continue polling.
6. If the background task is still running, loop back to step 1.
7. If the background task has finished, proceed to the Final Summary.

Final Summary

When the background task completes (or errors):

1. Read tasks/ralph/{name}/prd.md one final time — count completed and remaining.
2. Read the background task output via TaskOutput with block: false to check for errors.
3. Report:

   Ralph complete: {name}
   - Tasks completed: {completed}/{total}
   - Remaining: {remaining}
   - See tasks/ralph/{name}/progress.md for full details

4. If there are remaining - [ ] tasks, mention: "Run /ralph-loop {name} again to continue."
5. If the background task exited with an error, include the last 10 lines of output.

Rules

• Never commit: Do not run git add, git commit, or any git commands.
• Output location: Inherited from ralph.sh — files go into the plan directory unless PRD says otherwise.
• One task at a time: Inherited from ralph.sh — each iteration handles one task in a fresh claude session.
• Do not modify the PRD or progress files — ralph.sh handles that.
• Do not run ralph.sh inline — always use run_in_background: true.
