SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It transforms a vague or missing game idea into a structured, decision-ready game concept document by guiding interactive ideation, validating pillars, and aligning scope with feasibility.

Core Features & Use Cases

  • Guided collaborative ideation: Runs phased concept discovery and generation while asking key questions to capture your preferences and choices.
  • Concept-to-document pipeline: Produces 3 distinct concepts, refines the selected direction into core loop and player motivation, then writes a complete GDD at design/gdd/game-concept.md.
  • Vision alignment via studio-style gates: Applies pillar confirmation and review-mode logic (skips gates in solo/lean) and sets up follow-on pre-production steps.

Quick Start

Invoke the skill with: brainstorm roguelike --review lean.

FAQPage Schema
How do I turn a vague game idea into a structured game concept document?

To turn a vague game idea into a structured game concept document, you need guided ideation that validates design pillars and aligns scope with feasibility. This process produces a complete GDD with defined core loops and player motivations.

How do I generate multiple game design directions for pre-production?

Generating multiple game design directions for pre-production involves running phased concept discovery to produce three distinct concepts. You then refine the selected direction into a core loop and player motivation before writing the final document.

What is the best way to define core loops and player motivation for a GDD?

The best way to define core loops and player motivation for a GDD is through interactive concept discovery. Capturing your specific preferences and constraints allows you to validate design pillars and align the game scope with feasibility.

Can I use collaborative ideation for solo game development without review gates?

Yes, you can use collaborative ideation for solo game development without review gates. By applying a lean review mode, the process skips studio-style confirmation gates and directly captures your choices to output the concept document.

Where should I save the final game design document during concept ideation?

During concept ideation, you should save the final game design document as a markdown file at design/gdd/game-concept.md. This artifact includes a visual identity anchor and defines the next-step pre-production pipeline.

Does game concept ideation support resuming work on an existing GDD artifact?

Yes, game concept ideation supports resuming work on an existing GDD artifact. The process implements file read behaviors to detect your current document, allowing you to continue refining core loops and design pillars without losing progress.
