To enforce an 85% unit test coverage threshold, apply this skill to Gate 3 verification in TDD workflows to validate language-specific coverage commands and loop with implementers until the minimum threshold is met.

Map acceptance criteria to unit tests by generating a traceability matrix during post-implementation testing, ensuring every criterion is verified with executable tests and producing structured coverage reports for review.

Yes, you can use this skill to orchestrate TDD workflows for Python and TypeScript by guiding RED→GREEN→REFACTOR cycles and dispatching a QA analyst agent to write and run tests before code review.

The best way to verify acceptance criteria with executable unit tests is running post-implementation verification to close coverage gaps, block unverified code from progressing, and prepare handoff artifacts for the next gate.

Unit test coverage verification fails during Gate 3 when overall coverage drops below the 85% minimum threshold or acceptance criteria lack mapped executable tests, requiring implementers to loop and close gaps before escalation.
