SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It helps you quickly answer whether a game concept or mechanic is worth building by producing a timeboxed prototype and a decision-ready report.

Core Features & Use Cases

  • Rapid prototype planning: Turns a rough concept into a clear core question and a minimum viable implementation plan.
  • Timeboxed implementation with relaxed standards: Creates prototype code without production constraints and observes measurable behavior.
  • Decision report with Creative Director review: Produces a structured report and runs a gate playtest in full mode to confirm or override the recommendation.

Quick Start

Run the prototype skill with a short concept description and optionally add --review lean to generate a leaner decision report and recommendation.

FAQPage Schema
How do I validate a game mechanic with a throwaway prototype?

To validate a game mechanic with a throwaway prototype, define a focused hypothesis, implement minimal viable code without production constraints, and collect observable results to test the core question.

What is timeboxed game prototyping and when should I use it?

Timeboxed game prototyping is the process of rapidly testing a game concept's viability under strict time constraints. Use it to quickly determine if a mechanic is worth building before committing to full production.

How do I generate a decision report for a game prototype?

Generate a decision report for a game prototype by running a gate playtest in review mode and producing structured report generation to output a final PROCEED, PIVOT, or KILL recommendation.

Can I use minimal viable code to test a game concept hypothesis?

Yes, you can use minimal viable code to test a game concept hypothesis by applying relaxed production standards during timeboxed implementation and observing the measurable behavior.

How does a creative director review impact prototype validation?

A creative director review impacts prototype validation by running a gate playtest evaluation to confirm or override the initial recommendation, finalizing the PROCEED, PIVOT, or KILL decision.

What is the best way to decide whether to proceed, pivot, or kill a game idea?

The best way to decide whether to proceed, pivot, or kill a game idea is to test a focused hypothesis via timeboxed prototyping and evaluate the structured report through a creative director gate review.
