Format Until Clean
Run the formatter, fix any remaining style issues, and loop until the codebase formats cleanly with no diffs.
Kickoff prompt
Start the "Format Until Clean" loop.
Goal: formatter runs cleanly with no remaining diff
Max iterations: 5
Between iterations run: npm run format
Exit when: format command succeeds and git diff is empty
Step 1: Run the formatter. Fix any issues it cannot auto-fix, then repeat.
Self-pace this loop. After each iteration, run the check command, read the output, and only continue if the exit condition is not met. Stop when the exit condition passes or max iterations is reached. Give a short status update each pass.Basic information

Steps
- 1
Run formatter
Run the project formatter (prettier, biome, etc.).
npm run format - 2
Check diff
If formatting changed files, review diff for unintended edits. Fix manual style issues formatter missed.
- 3
Confirm clean
Re-run formatter and confirm working tree is stable.
npm run format && git diff --quiet
More Testing loops
Build Until Green
Run the production build, fix compile and bundling errors, and loop until the build succeeds.
Coverage Until Threshold
Add focused tests until coverage meets your threshold (e.g. 80%), without changing production behavior unnecessarily.
Pre-Commit Guard
Hook that runs tests before git commit commands to block commits when the suite is red.
Post-Edit Test Guard
Hook-based loop that runs related tests after file edits to catch regressions early.
Flaky Test Triage
Run failing tests repeatedly, classify each failure as flaky or real, and fix only confirmed regressions.
Autoloop TDD
Test-first loop: write a failing test, implement the minimum code to pass, refactor, and repeat.
