What problem does it solve? Task planning artifacts (prd.md, design.md, implement.md) often drift from the original requirements document through misinterpretation, omission, embellishment, or inconsistent UI copy, and these errors surface only after development begins. This Skill performs a systematic bidirectional audit of the planning documents against the authoritative requirements before coding starts. ## Core Features & Use Cases - Bidirectional PRD verification: Forward-checks every PRD item against the original requirements and reverse-scans the requirements for uncovered or partially covered changes, including scattered field-level edits. - Cross-layer consistency checks: For complex tasks, verifies design.md and implement.md trace back to the PRD, flags out-of-scope additions, and detects naming, UI copy, and boundary drift across all three documents. - Version planning validation: When a version plan with task candidates and waves exists, checks task cohesion, requirement-to-task-to-wave coverage, wave testability, and creation ordering. - Use Case: After generating a PRD, design, and implementation plan for a feature, run this Skill with the original requirements doc to get one consolidated deviation report and a single confirmed fix list applied in batch. ## Quick Start Ask the AI to verify the current task's prd.md, design.md, and implement.md against the original requirements document and produce one consolidated correction list.
