What problem does it solve? Game design documents often reach programmers with missing sections, broken cross-references, untestable acceptance criteria, or formulas that break at boundary values, causing costly rework during implementation. ## Core Features & Use Cases - Structured Completeness Audit: Checks the GDD against an 8-section design standard covering overview, player fantasy, rules, formulas, edge cases, dependencies, tuning knobs, and acceptance criteria. - Adversarial Specialist Review: In full mode, spawns parallel domain subagents (game-designer, systems-designer, economy-designer, qa-lead, and others) that challenge the design, plus a creative-director synthesis for the final verdict. - Dependency and Re-review Tracking: Validates that every referenced system GDD exists on disk, reads prior review logs, and produces a verdict (APPROVED / NEEDS REVISION / MAJOR REVISION NEEDED) with a scope signal. - Use Case: Before handing a combat-system GDD to programmers, run the review to catch a missing Edge Cases section, a damage formula that divides by zero at minimum inputs, and a dependency on a loot-system document that does not exist yet. ## Quick Start Ask the AI to run the design-review skill on your GDD file, for example: review design/gdd/combat-system.md at full depth and report blocking issues before implementation.
