Claude Code is an agentic coding tool that lives in your terminal, understands your codebase, and helps you code faster by executing routine tasks, explaining complex code, and handling git workflows - all through natural language commands.

What is the Ralph Wiggum Technique?
The Ralph Wiggum technique is an iterative development methodology based on continuous AI loops, pioneered by Geoffrey Huntley.
Core concept:
while :; do
cat PROMPT.md | claude-code --continue
done
The same prompt is fed to Claude repeatedly. The "self-referential" aspect comes from Claude seeing its own previous work in the files and git history, not from feeding output back as input.
Each iteration:
- Claude receives the SAME prompt
- Works on the task, modifying files
- Tries to exit
- Stop hook intercepts and feeds the same prompt again
- Claude sees its previous work in the files
- Iteratively improves until completion
The technique is described as "deterministically bad in an undeterministic world" - failures are predictable, enabling systematic improvement through prompt tuning.
Available Commands
/ralph-loop <PROMPT> [OPTIONS]
Start a Ralph loop in your current session.
Usage:
/ralph-loop "Refactor the cache layer" --max-iterations 20
/ralph-loop "Add tests" --completion-promise "TESTS COMPLETE"
Options:
--max-iterations <n>- Max iterations before auto-stop--completion-promise <text>- Promise phrase to signal completion
How it works:
- Creates
.claude/.ralph-loop.local.mdstate file - You work on the task
- When you try to exit, stop hook intercepts
- Same prompt fed back
- You see your previous work
- Continues until promise detected or max iterations
/cancel-ralph
Cancel an active Ralph loop (removes the loop state file).
Usage:
/cancel-ralph
How it works:
- Checks for active loop state file
- Removes
.claude/.ralph-loop.local.md - Reports cancellation with iteration count
Key Concepts
Completion Promises
To signal completion, Claude must output a <promise> tag:
<promise>TASK COMPLETE</promise>
The stop hook looks for this specific tag. Without it (or --max-iterations), Ralph runs infinitely.
Self-Reference Mechanism
The "loop" doesn't mean Claude talks to itself. It means:
- Same prompt repeated
- Claude's work persists in files
- Each iteration sees previous attempts
- Builds incrementally toward goal
Example
Interactive Bug Fix
/ralph-loop "Fix the token refresh logic in auth.ts. Output <promise>FIXED</promise> when all tests pass." --completion-promise "FIXED" --max-iterations 10
You'll see Ralph:
- Attempt fixes
- Run tests
- See failures
- Iterate on solution
- In your current session
When to Use Ralph
Good for:
- Well-defined tasks with clear success criteria
- Tasks requiring iteration and refinement
- Iterative development with self-correction
- Greenfield projects
Not good for:
- Tasks requiring human judgment or design decisions
- One-shot operations
- Tasks with unclear success criteria
- Debugging production issues (use targeted debugging instead)
