# test-first

Use this skill after reading the task instruction.

1. Inspect files already in `/app`.
2. Implement exactly the output files the instruction asks for.
3. Re-read each output file and confirm it is non-empty.
4. Write `/app/skill_applied.json` with the skill name so logs can prove the skill ran.

Do not read `/tests`, `/solution`, or any hidden answer files.
