Game concept generation transforms informal ideas, vague themes, and scattered inspiration into a cohesive game concept document through guided multi-phase ideation, covering core loop design, pillar definition, and scope estimation for pre-production.

Core loop design and pillar definition are handled through interactive ideation prompts that analyze player motivations, establish anti-pillars, and apply scope consistency rules to ensure your game concept is feasible for solo or small-team development.

Yes, this workflow is designed specifically for solo or small-team pre-production, applying scope and feasibility assessments alongside iterative user prompts to ensure the generated game concept matches your development capacity.

A production-ready game concept document is generated by running discovery, concept generation, and scope estimation phases, then writing the finalized output with a visual identity anchor and explicit next steps into standard markdown templates.

The process reads existing design files if present in the design/gdd directory and utilizes .claude/docs/templates/game-concept.md to write the finalized document, though interactive user responses guide the generation from scratch.

Full review mode spawns director, producer, and technical gate tasks to evaluate the game concept, while lean review skips these gating tasks, offering a faster ideation process for earlier pre-production iterations.
