Super Ralph Wiggum

Super Ralph Wiggum

Autonomous iteration loops for Claude Code. Run the same prompt repeatedly until task completion, with context persisting through files and git history.

The Ralph Philosophy

The agent chooses the task, not you.

You define the end state. Ralph figures out how to get there.

With multi-phase plans, a human writes a new prompt at the start of each phase. With Ralph, the agent picks what to work on next from your PRD. You describe the destination. Ralph navigates.

The 11 Tips (Quick Reference)

Based on AI Hero's definitive guide:

See @references/tips-and-tricks.md for detailed guidance on each tip.

Quick Start

To start a Ralph loop with a template:

Run the super-ralph-wiggum skill with the test-coverage template, max 20 iterations

To start with a PRD file:

Run super-ralph-wiggum with feature-prd template using ./prd.json

Available Templates

Invocation Patterns

Template Mode (Recommended)

Use a pre-built template for common tasks:

Use super-ralph-wiggum with [template-name] template
Options: --max-iterations N, --browser (for UI verification)

PRD Mode

For structured feature development with task tracking:

Use super-ralph-wiggum with feature-prd template
PRD file: ./prd.json

The PRD file tracks features with passes: true/false. Loop completes when all features pass.

HITL Mode (Single Iteration)

For interactive learning and pair programming:

Use super-ralph-wiggum with --once flag to [task description]

Runs ONE iteration without looping. Great for learning how Ralph works.

Custom Prompt

For tasks not covered by templates:

Use super-ralph-wiggum with custom prompt:
[Your detailed task description with completion criteria]
Completion: Output <promise>COMPLETE</promise> when done
Max iterations: 15

The Two Modes: HITL vs AFK

The progression is simple:

1. Start with HITL to learn and refine
2. Go AFK once you trust your prompt
3. Review the commits when you return

For AFK, always cap iterations:

• Small tasks: 5-10 iterations
• Medium tasks: 15-30 iterations
• Large features: 30-50 iterations

Explicitly Define Software Quality

Ralph doesn't know if this is a throwaway prototype or production code. Tell it.

Code Quality Prompt

If the loop should maintain high code quality, specify it factually:

Maintain existing code conventions and quality standards. Each change should leave test coverage equal to or better than before. Prefer incremental improvements over large rewrites.

Avoid motivational framing ("fight entropy", "be thorough")—Claude 4.6 already tends toward thoroughness and these amplify it into over-planning. Factual quality criteria are more effective.

The Repo Wins

Your instructions compete with your codebase. When Ralph explores your repo, it sees two sources of truth: what you told it to do and what you actually did.

If you write "never use any types" but Ralph sees any throughout your existing code, it will follow the codebase, not your instructions.

Claude learns patterns from the existing codebase. If the codebase uses any types throughout, the loop will follow that pattern regardless of instructions. Clean up the specific patterns you care about before running the loop.

Task Prioritization Order

When choosing the next task, Ralph should prioritize:

1. Architectural decisions and core abstractions
2. Integration points between modules
3. Unknown unknowns and spike work
4. Standard features and implementation
5. Polish, cleanup, and quick wins

Fail fast on risky work. Save easy wins for later.

Use HITL Ralph for early architectural decisions—the code from these tasks stays forever. Save AFK Ralph for when the foundation is solid.

Execution Modes

1. In-Session Mode (Default)

Loop runs inside your current Claude Code session using stop hooks:

Use super-ralph-wiggum with test-coverage template, max 20 iterations

• Stop hook intercepts exit attempts
• Same prompt fed back each iteration
• Context persists through files and git
• Best for interactive/monitored work

2. Dockerized Mode (External)

Loop runs externally via bash script with Docker sandbox:

# Generate external script
./scripts/setup-ralph-loop.sh --template test-coverage --docker > run-ralph.sh
chmod +x run-ralph.sh

# Run in background
./run-ralph.sh 20 &

• Each iteration is a fresh Claude Code instance
• Docker isolation for safety
• Best for overnight/AFK runs
• Memory persists only via files

Essential for AFK safety: Docker sandboxes let Ralph edit project files and commit—but can't touch your home directory, SSH keys, or system files.

How It Works

1. Setup: Creates state file at .claude/ralph-loop.local.md
2. Progress: Auto-creates progress.txt in project root
3. Loop: Stop hook intercepts exit, feeds same prompt back
4. Completion: Detects <promise>COMPLETE</promise> or PRD all-pass
5. Learning: Patterns accumulate in progress.txt across iterations

Key Options

Best Practices

1. Small Stories

Tasks must fit in one context window. Break large features into atomic stories.

2. Verification First

Always run typecheck + tests before committing. Templates enforce this.

3. Cap Iterations

For AFK (unattended) Ralph, always set --max-iterations. Infinite loops are dangerous with stochastic systems.

4. Clear Completion Criteria

Vague tasks risk infinite loops. Be explicit about when to stop.

5. Use Progress File

Previous iteration learnings persist in progress.txt. Templates auto-inject this.

6. One Change Per Commit

Keep changes small and focused. Prefer multiple small commits over one large commit.

7. Structure State Appropriately

Use JSON for structured progress data (coverage percentages, feature pass/fail, migration counts). Use freeform text in progress.txt for observations and session learnings. Use git commits as checkpoints between iterations so each new context window can discover state from the filesystem.

Template Details

test-coverage

Improves test coverage by:

1. Running coverage to find gaps
2. Identifying most important untested user-facing behavior
3. Writing ONE meaningful test per iteration
4. Using /* v8 ignore */ for non-essential code
5. Committing after each successful test

feature-prd

Implements features from a PRD file by:

1. Reading prd.json for highest-priority incomplete feature
2. Checking dependencies are satisfied
3. Implementing ONE feature per iteration
4. Running verification (typecheck + tests)
5. Updating AGENTS.md with patterns discovered
6. Marking feature as passes: true

Canceling a Loop

To stop an active Ralph loop, delete the state file:

rm .claude/ralph-loop.local.md

Or wait for max iterations to be reached.
