Takes your PRD or requirements doc and generates structured test cases with proper coverage mapping. You get functional tests, edge cases, error handling, and state transitions organized into a markdown file with a traceability matrix. Each test case includes preconditions, steps, expected results, and links back to specific requirements. The workflow is thorough: it reads your PRD, extracts scenarios, validates coverage gaps, then outputs everything to tests/ with TC-F, TC-E, TC-ERR, and TC-ST prefixes. Best for when you need QA documentation that maps cleanly to requirements rather than just ad hoc test ideas. The requirement-driven approach means you won't ship features without corresponding test coverage.
