What problem does it solve? Spec-driven development drifts: requirements lose task coverage, code diverges from the approved spec, and constitution constraints get violated silently. This Skill audits a MySpec specification bundle read-only and reports exactly what is missing, contradictory, or unimplemented before those gaps reach production. ## Core Features & Use Cases - Spec Consistency Mode: Checks constitution alignment, requirement quality (EARS+ criteria, measurable NFR targets), solution completeness, task coverage, dependency cycles, and sizing across the bundle. - Convergence Mode: Compares the repository against the spec, classifying every requirement as implemented, partial, missing, contradicts, or unrequested, and detects checkbox drift and constitution drift. - Severity-Ranked Reporting: Produces a findings table (CRITICAL to LOW) plus a coverage matrix showing requirement-to-task and requirement-to-test traceability percentages. - Use Case: Before a milestone review, ask whether the code matches the spec; the Skill greps tests for requirement ids, reads the modules named in solution.md, and reports that 18 of 20 requirements have tasks with FR-014 and NFR-003 uncovered. ## Quick Start Ask the assistant to analyze the spec bundle for project X and check whether the code matches the spec.
