Test Harness Skill
Use this when the central question is verification.
Method
- Identify the behavior boundary.
- Choose the smallest falsifying check.
- Run focused checks before broad suites.
- Attribute failures before fixing anything.
- Report skipped checks plainly.
- Recommend broader validation only when risk justifies it.
Failure Categories
- product behavior regression;
- test expectation drift;
- missing dependency or environment setup;
- stale path or fixture assumption;
- unrelated pre-existing failure.
