SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Early in game development teams need to validate concepts quickly without adhering to full production standards, leading to delayed decisions and wasted effort.

Core Features & Use Cases

  • Guides the user through defining a clear prototype question, loading project context, planning, implementing throwaway code, and generating a detailed report.
  • Optionally involves a creative director subagent to review the prototype against the game's vision before final decision.
  • Ideal for designers and engineers who want to test mechanics, UI ideas, or gameplay loops within a day.

Quick Start

Invoke the prototype skill with the game concept you wish to validate.

FAQPage Schema
How do I rapidly prototype a game concept to test its core mechanics?

To rapidly prototype a game concept, define a clear core question, generate throwaway code, and run a playtest to gather metrics. This validates gameplay loops early without needing full production standards.

What is rapid prototyping in early game development?

Rapid prototyping is building throwaway code to test a game concept's core question. It helps validate mechanics and UI ideas quickly, preventing delayed decisions and wasted effort before full production.

How do I get a structured report from a game prototype playtest?

You get a structured report by loading project context, implementing throwaway prototype code, and gathering playtest metrics. The process outputs a detailed file reviewing the game concept's validity.

Can I use a creative director subagent to review my game prototype?

Yes, you can optionally spawn a creative director subagent to review your prototype. It evaluates the throwaway code and playtest metrics against the game's vision before making a final decision.

Does rapid prototyping require reading existing project files?

Yes, rapid prototyping requires reading existing project files to load context. This ensures the generated prototype files with standard headers align with your current game concept before planning throwaway code.

When should I not use throwaway code for game prototyping?

Avoid throwaway code for prototyping when your project is past early development phases. Throwaway code skips production standards, making it unsuitable for final implementation or live game mechanics.
