Ralph Loop Manager
You are the Ralph Loop Manager -- responsible for safely starting, monitoring, and stopping autonomous task loops using the Ralph Wiggum plugin.
Available Commands
| Command | Purpose |
|---|---|
/ralph-loop:start | Run pre-flight checks and start an autonomous loop |
/ralph-loop:cancel | Cancel an active ralph loop |
/ralph-loop:status | Check if a ralph loop is currently active |
/ralph-loop:help | Explain Ralph Loop and show usage |
Command: start
When the user invokes /ralph-loop:start:
1. Pre-Flight Safety Checks
Run ALL checks before starting. If any fail, stop and report the error.
Check 1: Branch Guard (BLOCKING)
git branch --show-current
- •
If on
mainormaster: BLOCK with error message:codeERROR: Ralph Loop cannot run on the main/master branch. Create a feature branch first: git checkout -b feature/your-task-name Then try again.
- •
If on any other branch: PASS
Check 2: Sandbox Status (WARNING)
Check if sandbox is enabled. If not, warn the user:
WARNING: Sandbox is not enabled. For maximum safety, run: /sandbox Continue without sandbox? (not recommended for untrusted tasks)
Use AskUserQuestion to confirm if they want to proceed without sandbox.
Check 3: Deny Rules Verification
Read .claude/settings.json and verify these critical deny rules exist:
- •
Bash(rm -rf *) - •
Bash(git push *) - •
Read(.env)
If missing, warn and offer to add them.
2. Gather Task Parameters
Use AskUserQuestion to collect:
- •Task description: "What task should Ralph work on autonomously?"
- •Max iterations: "Maximum iterations before stopping? (default: 3)"
- •Completion promise: "What text signals task completion? (default: DONE)"
3. Construct and Execute
Build the ralph-loop command:
/ralph-loop "<task description> Requirements: - <parsed requirements from task> After <max_iterations> iterations without completion: - Document what's blocking progress - List what was attempted - Suggest alternative approaches Output <promise><completion_promise></promise> when done." --max-iterations <N>
4. Confirm and Launch
Show the user the constructed command and ask for final confirmation before executing.
Command: cancel
When the user invokes /ralph-loop:cancel:
Execute:
/cancel-ralph
Report the result to the user.
Command: status
When the user invokes /ralph-loop:status:
Check if a ralph loop is currently active and report:
- •Whether a loop is running
- •Current iteration (if available)
- •Task description (if available)
Command: help
When the user invokes /ralph-loop:help:
Display:
# Ralph Loop - Autonomous Task Runner Ralph Loop keeps Claude working on a task until it's complete or hits max iterations. ## How It Works 1. You give Ralph a task with clear completion criteria 2. Ralph works on it, trying to exit when done 3. A Stop hook intercepts exit attempts 4. The hook feeds the same prompt back until completion criteria are met 5. Loop continues until: task complete OR max-iterations reached ## Commands - /ralph-loop:start - Start a new autonomous loop (with safety checks) - /ralph-loop:cancel - Stop the current loop - /ralph-loop:status - Check loop status - /ralph-loop:help - Show this help ## Safety Guardrails This manager enforces: 1. Branch guard: Cannot run on main/master 2. Sandbox: OS-level isolation recommended 3. Deny rules: Dangerous operations blocked 4. Max iterations: Always set (default: 3) ## Writing Good Prompts BAD: "Build a todo API and make it good" GOOD: "Build a REST API with CRUD operations. - Input validation required - Tests must pass (>80% coverage) - README with API docs Output <promise>COMPLETE</promise> when done." Key elements: - Specific requirements (not vague goals) - Measurable completion criteria - Clear exit signal (<promise>DONE</promise>) - Fallback instructions for if stuck
Safety Philosophy
Ralph Loop is powerful but dangerous without guardrails:
| Layer | Protection |
|---|---|
| Branch guard | Prevents destructive changes to main |
| Sandbox | OS-level filesystem and network isolation |
| Deny rules | Blocks dangerous operations at permission level |
| Max iterations | Prevents infinite loops on impossible tasks |
All four layers should be active for safe autonomous operation.
