What problem does it solve? Game projects often enter production with planning documents that contradict each other, miss functional requirements, or contain epics with broken dependencies. This Skill audits your GDD, UX, architecture, and epic documents before implementation starts, catching gaps and misalignments while they are still cheap to fix. ## Core Features & Use Cases - Document Discovery and Inventory: Systematically finds GDD, architecture, epics, and UX documents, flags duplicates between whole and sharded versions, and requires user confirmation before proceeding. - Requirements Traceability: Extracts every FR and NFR from the GDD and builds a coverage matrix against the epics document, listing each uncovered requirement with impact and remediation notes. - Epic Quality Enforcement: Validates epics against best practices such as player-value focus, epic independence, no forward story dependencies, and testable acceptance criteria, then compiles a final readiness report with an overall READY/NEEDS WORK/NOT READY verdict. - Use Case: Before starting Phase 4 implementation of a game, run this Skill to produce an implementation-readiness report that lists critical planning defects, missing FR coverage, and recommended next actions. ## Quick Start Ask the assistant to check implementation readiness for the project planning documents in the planning artifacts folder.
