Grind Until Pass

Use this skill when you want the agent to keep working autonomously until a specific goal is met — all tests pass, the build succeeds, or linting is clean. Instead of stopping after one attempt, the agent loops until done.

Steps

1. Define the goal command — the command whose exit code determines success:

   • Tests: npm test or npx vitest run
   • Build: npm run build
   • Lint: npm run lint
   • Type-check: npx tsc --noEmit
   • All of the above: npm run lint && npx tsc --noEmit && npm test && npm run build

2. Run the command — execute it and capture the output.

3. If it fails — analyze and fix:

   • Read the error output carefully.
   • Identify the root cause: failing test assertion, type error, lint violation, import error, etc.
