What problem does it solve? Turning a vague game idea into a structured, production-ready concept is hard for solo developers and small teams. This Skill facilitates a professional studio-style ideation process that produces a complete game concept document with pillars, core loops, and scope definitions. ## Core Features & Use Cases - Six-Phase Guided Ideation: Walks through creative discovery, concept generation, core loop design, pillars and anti-pillars, player type validation, and scope feasibility using frameworks like MDA, Bartle taxonomy, and Self-Determination Theory. - Role-Gate Reviews: Optionally spawns creative-director, art-director, technical-director, and producer subagent gates to validate pillars, visual direction, feasibility, and scope based on a configurable review mode (full, lean, solo). - Structured Document Output: Generates a filled game concept document at design/gdd/game-concept.md from a template, including a Visual Identity Anchor section that seeds the art bible. - Use Case: A solo developer with only a genre hint like "cozy farming" runs the skill, answers interactive questions, selects from three generated concepts, locks in pillars, and receives a complete concept document plus an ordered pre-production pipeline of next steps. ## Quick Start Ask the AI to run the brainstorm skill with an optional genre hint such as "roguelike" to start a guided game concept ideation session.
