What problem does it solve? Turning a high-level game concept into an actionable design plan is hard: concept documents rarely enumerate every system, hidden dependencies cause design-order mistakes, and teams lack a shared index tracking which systems are designed. This Skill decomposes a game concept into a complete, dependency-sorted, priority-tiered systems index. ## Core Features & Use Cases - Systems Enumeration: Extracts explicit systems from the concept doc and infers implicit ones (e.g., combat implies damage calculation, status effects, combat UI), then validates the list with the user. - Dependency Mapping & Prioritization: Builds a layered dependency graph (Foundation through Polish), detects circular dependencies and bottleneck systems, and assigns MVP/Vertical Slice/Alpha/Full Vision priority tiers. - Systems Index & Handoff: Writes design/gdd/systems-index.md with a progress tracker, then hands off individual system GDD authoring to the /design-system skill. - Use Case: After brainstorming a game concept, run /map-systems to get a full systems breakdown, then run /map-systems next to automatically pick the highest-priority undesigned system and start its GDD. ## Quick Start Ask the AI to run /map-systems to decompose the game concept in design/gdd/game-concept.md into a prioritized systems index.
