What problem does it solve? Traceability matrices, status reports, and READMEs drift out of sync with actual source code over time, so plans built on them waste implementation effort on features that already exist or miss ones that do not. This Skill verifies documentation claims against real code and test evidence before planning, release, or modernization. ## Core Features & Use Cases - Parallel Source Audit: Delegates module-by-module reading of every source file to subagents, capturing implemented behavior, REQ references, TODOs, and test coverage. - Document Cross-Check: Diffs SRS requirement IDs against traceability matrices, validates appendix file lists and line counts, and flags stale status claims. - Legacy Health Mode: Extends the audit to inherited codebases by building and testing owned projects, checking demo surfaces, stub code, and security risks, then ranking findings by severity. - Use Case: Before drafting a multi-phase refactoring plan, run the audit to discover that requirements marked "Not Implemented" are already coded and tested, cutting the planned scope and producing a corrected traceability matrix. ## Quick Start Ask the agent to audit this project's implementation status, tests, documentation, and traceability drift, and to output severity-ranked file:line evidence with a correction order.
