What problem does it solve? Turning a high-level game concept into an actionable design plan is hard: concepts rarely list every system, dependencies are unclear, and teams design systems in the wrong order. This Skill guides a structured decomposition of a game concept into a complete, dependency-ordered systems index. ## Core Features & Use Cases - Systems Enumeration: Extracts explicit systems from the game concept and infers hidden implicit systems (e.g., combat implies damage calculation, status effects, and combat UI), with collaborative user review. - Dependency Mapping & Prioritization: Builds a layered dependency graph (Foundation through Polish), detects circular dependencies and bottleneck systems, and assigns MVP/Vertical Slice/Alpha priority tiers. - Systems Index & Handoff: Writes a systems index to design/gdd/systems-index.md with design order and progress tracking, then hands off individual GDD authoring to the design-system skill. - Use Case: After brainstorming a tower defense concept, run the full workflow to enumerate 20+ systems, order them by dependency, and identify which MVP systems to design first. ## Quick Start Ask the AI to run $ai-game-studio:map-systems to decompose your game concept into a prioritized systems index.
