test-spec-checker
Audit test coverage as living specification by comparing implementation against test cases. Detects specification gaps (public APIs without tests), contradictions (tests asserting behavior that differs from implementation), stale tests (testing removed/changed code), and missing edge cases. Use this skill when the user asks to check test coverage, verify spec coverage, audit tests, find contradictions between tests and code, or ensure tests serve as reliable specification. Also trigger for phrases like "are my tests up to date", "do tests match the implementation", "spec coverage", "test audit", "仕様カバレッジ", "テストと実装の矛盾", "テストの網羅性". Supports scoped checks (e.g., "check CLI spec coverage", "audit TUI tests") as well as full-project audits.
