What problem does it solve? Game design documents often contain orphan mechanics, contradictory sections, unrealistic scope, and misaligned mechanics versus target aesthetics that go unnoticed until implementation. This Skill performs a structured nine-step review that catches these problems while they are still cheap to fix. ## Core Features & Use Cases - Pillar Alignment & MDA Consistency: Maps every mechanic to design pillars and checks whether described mechanics actually deliver the target aesthetics, flagging orphan features and gaps. - Psychology & Feasibility Review: Evaluates the design through Self-Determination Theory and Flow Theory, plus scope feasibility against team capacity, edge cases, and onboarding. - Severity-Rated Report: Produces a Design Review Report with Critical/Major/Minor findings, each citing specific document sections with actionable recommendations. - Use Case: Before starting implementation, a designer submits their GDD and receives a report identifying that the crafting system serves no design pillar and that the difficulty curve contradicts the stated casual target audience. ## Quick Start Ask the AI to review the game design document at a given path and produce a severity-rated design review report.
