What problem does it solve?
This Skill prevents regressions from slipping through by tying bug fixes and critical product paths to an explicit test coverage manifest. It helps teams spot missing regression tests, stale coverage, and new features that have outpaced the test suite before a release gate.
Core Features & Use Cases
- Coverage Audit: Compare existing tests against critical acceptance criteria, formulas, edge cases, and known bug fixes.
- Regression Gap Detection: Identify bugs that were fixed but never backed by a test, and flag missing coverage for newly completed work.
- Suite Maintenance: Maintain a curated regression manifest that teams can review before shipping or during sprint closeout.
- Use Case: After a bug fix lands, use this Skill to verify that a test already protects the failure mode or to recommend the exact missing regression test.
Quick Start
Ask the skill to audit or update regression coverage for the current repository and prepare the changes for tests/regression-suite.md only after you approve them.
