Ralph Wiggum Loop
Unlimited autonomous iteration pattern in Claude Code. The Ralph Wiggum plugin launches a loop: Claude attempts the task, evaluates the result, retries until success or max iterations. Useful for tasks with clear success criteria (passing tests, clean build, zero linter warnings). Named after the Simpsons character who "keeps trying until he gets it".
Strengths
- Autonomous iteration until success, zero human intervention on repetitive tasks
- Ideal for CI pipelines: passing tests, clean build, zero linter warnings
- Eliminates the manual "run → observe → fix → repeat" cycle for automatable tasks
Limitations
- Risk of infinite loop if success criteria are poorly defined or never reachable
- High token consumption, each iteration = a full API call
- Dangerous on file modification tasks without rollback, hard to undo failed iterations
Best for
- Automatic bug fixing until the full test suite passes
- TypeScript type resolution until npx tsc --noEmit returns 0 errors
- Automatic linter fixing until biome check returns no warnings
