What problem does it solve? Project documentation drifts out of sync with the actual codebase: requirement counts go stale, traceability matrices miss REQ IDs, appendix file lists are never updated, and status headers claim work that Git history contradicts. This Skill systematically verifies that SRS documents, traceability matrices, design docs, READMEs, ADRs, and change records tell the truth about what the code actually does. ## Core Features & Use Cases - Full-Project Parallel Audit: Dispatches three parallel subagents to read every source and test file across module clusters (Domain/Interop, Services/Dto, Components), then cross-references findings against all documentation layers to produce a priority-ranked gap report. - Targeted Change-Record Mode: Read-only verification of a single remediation note, fix record, or release note against the current working-tree diff, mapping every checkable claim to file:line and test evidence. - Cross-Reference Automation: Uses grep/comm pipelines to diff REQ IDs between SRS and traceability, compares claimed counts against find/wc/dotnet test output, and classifies gaps into critical, high, and low priority tiers. - Use Case: After a major refactoring phase, ask for a documentation audit to discover that the SRS claims 151 requirements but actually defines 152, the traceability appendix is missing 12 test files, and a design doc marked "pending" was merged weeks ago — then apply fixes in verified batches. ## Quick Start Ask the agent to verify that the project README, SRS, and traceability matrix accurately reflect the current source code and tests, starting with a read-only audit.
