What problem does it solve? It answers whether implemented code actually covers every acceptance criterion of a user story, work item, or feature, producing an auditable traceability matrix instead of relying on manual checks. ## Core Features & Use Cases - Criteria-to-test traceability: Maps each acceptance criterion (verbatim identifiers like AC-001, 1.1, R-3) to test cases (TC-XXX) and automated test artifacts, classifying each as COVERED, PARTIAL, or UNCOVERED. - Delegated test execution: Reuses fresh quality-check run results or triggers a tests-only run, never executing the suite itself, and reports PASS/FAIL/NOT_RUN per matrix row. - Idempotent reporting: Generates a coverage.md report with a verdict (APPROVED, APPROVED_WITH_NOTES, REJECTED) and fingerprint markers so unchanged work is not revalidated. - Use Case: Before merging a branch for US-042, ask the agent to validate its coverage; it reads the story's criteria and test-cases folder, cross-references repository tests, and saves a coverage.md verdict next to the artifact. ## Quick Start Ask the agent to verify that the code covers the acceptance criteria of US-042 and generate the coverage report.
