What problem does it solve? Plans, requirements, architecture notes, and task lists often drift apart as a project evolves, leading to contradictions, missing acceptance criteria, and stale references that only surface during implementation. This Skill performs a read-only consistency audit across those artifacts so problems are caught before any code is written. ## Core Features & Use Cases - Traceability Matrix: Maps each requirement or acceptance criterion to its design decision, implementing tasks, and validation evidence with exact path:line citations. - Consistency Checks: Detects contradictions between sources, conflicting terminology, orphaned tasks, broken dependency ordering, and validation commands that cannot observe the stated acceptance criteria. - Classified Findings Report: Separates confirmed coverage from assumptions, unresolved decisions, contradictions, and stale references, then issues a verdict of ready, needs clarification, or plan revision required. - Use Case: After decomposing a feature into tasks, run this review to confirm every requirement has a task and test path, and that no two documents disagree, before approving implementation. ## Quick Start Review the current plan, requirements, and task artifacts for contradictions and missing coverage, and report findings without editing any files.
