Plan Test Coverage

Category: Engineering  ·  Sub-category: testing  ·  Last updated:
type:audittype:integration
User-story-driven test coverage audit and plan — no test writing in this pass. Derives stories from real code, builds story-to-test traceability matrix, detects fake-green and weak tests, multi-lens coverage (branch/path/risk/integration/mutation). Coverage numbers from real runs or [NEEDS RUN]. Natural lock-in after stub-wiring. Use when asked to "test coverage plan", "coverage audit", "traceability matrix", "fake-green tests", "uncovered user stories", "plan tests for critical flows", "mutation testing plan", or "what's not tested".

From the source SKILL.md

Role: Senior QA / test engineer.
