SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Turning a vague game idea into a structured, production-ready concept is hard: solo developers skip validation, lose track of pillars, and over-scope. This Skill runs a facilitated, multi-phase ideation session that produces a complete game concept document grounded in professional studio techniques. ## Core Features & Use Cases - Six-phase guided ideation: creative discovery, concept generation (verb-first, mashup, MDA-backward), core loop design, pillars and anti-pillars, player type validation, and scope feasibility. - Role-gate reviews: optionally spawns creative-director, art-director, technical-director, and producer subagent gates (CD-PILLARS, AD-CONCEPT-VISUAL, TD-FEASIBILITY, PR-SCOPE) with solo/lean/full review modes. - Structured output: writes a filled game concept document to design/gdd/game-concept.md including MDA analysis, player motivation profile, and a Visual Identity Anchor section. - Use Case: A solo developer with only a 'cozy farming' hint runs the skill, answers interactive questions, selects one of three generated concepts, locks pillars, and receives a scoped concept document plus an ordered pre-production pipeline. ## Quick Start Ask the AI to run the brainstorm skill with an optional genre hint like 'roguelike' to start a guided game concept ideation session.

Frequently Asked Questions about brainstorm

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I brainstorm a game concept with AI?▼

Invoke the brainstorm skill with an optional genre or theme hint, such as 'roguelike' or 'cozy farming'. It runs six interactive phases covering discovery, concept generation, core loop design, pillars, player validation, and scope, then writes a structured concept document.

What frameworks does game concept ideation use?▼

The skill applies verb-first design, the mashup method, and experience-first design based on the MDA framework. It also uses Self-Determination Theory for motivation analysis and the Bartle taxonomy plus Quantic Foundry model for player type validation.

Can I use this with Unity, Godot, or Unreal projects?▼

Yes. The skill asks about your target platform and engine experience during the scope phase and records your preference. If you have no engine preference, it directs you to the setup-engine skill rather than forcing a recommendation.

What are the solo, lean, and full review modes?▼

Review modes control whether role-gate subagent reviews run. Solo and lean modes skip gates like CD-PILLARS, TD-FEASIBILITY, and PR-SCOPE for faster sessions, while full mode spawns creative-director, art-director, technical-director, and producer reviews.

Where is the game concept document saved?▼

The completed concept is written to design/gdd/game-concept.md after you approve the write. It is generated from the template at .ai-game-studio/templates/game-concept.md and includes pillars, core loop, MDA analysis, scope tiers, and a Visual Identity Anchor section.

What happens if the session runs out of context mid-brainstorm?▼

If context reaches 70 percent, the skill warns you and notes that progress is saved to design/gdd/game-concept.md. You can open a fresh session and resume, since the skill checks for existing concept work before restarting.
