review-all-gdds

What problem does it solve?

This Skill identifies cross-document contradictions, stale references, ownership conflicts, formula mismatches, and emergent game-design issues that only appear when multiple system GDDs are considered together, preventing inconsistent design from being baked into architecture.

Core Features & Use Cases

• Multi-pass loading and scanning: fast summary extraction, optional registry pre-load, and full-document reads to limit token usage and focus scope.
• Consistency checks: bidirectional dependency verification, rule contradiction detection, stale reference identification, tuning-knob ownership checks, and formula range compatibility analysis.
• Game-design holism: progression loop competition, cognitive load assessment, dominant-strategy detection, economic loop mapping, difficulty curve alignment, pillar alignment, and player-fantasy coherence.
• Cross-system walkthroughs and reporting: scenario-by-scenario interaction walks, severity categorization (Blocker/Warning/Info), user confirmation for report writing, optional systems-index updates, and session-state recording.
• Use Case: run after MVP GDDs are drafted (or after a major revision) to surface blocking contradictions and design hazards before creating architecture.

Quick Start

Run the review-all-gdds skill with no arguments to perform a full cross-GDD consistency and design-theory review across the design/gdd directory.
