Fix and Test

Run a fix-test loop: identify failing tests, fix them, re-run tests, repeat until green.

Use this when the codebase is already in a failing state and the goal is recovery. Do not use this for greenfield feature delivery (use tdd) or structural cleanup of already-green code (use refactor).

What to do

1. If the user provided an argument, use it as the test command (for example npm test -- auth). Otherwise use npm test.
2. Run the command and triage existing failures.
3. Fix production code first; only edit tests when they are demonstrably wrong.
4. Re-run the same command and iterate until green (max 5 passes).
5. Once scoped tests are green, run full npm test before declaring done.

Flow

flow:
  retry max 5
    run: npm test
    if command_failed
      prompt: Analyze the test failures above and fix the underlying code. Do not modify tests unless they are genuinely wrong.
    end
  end

done when:
  tests_pass

Rules

• Focus on fixing the source code, not the tests, unless the tests themselves are incorrect.
• During active triage you may run a scoped test command, but finish with the full suite.
• If you cannot fix a test after 5 attempts, explain what you tried and why it's failing.
