SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Rapid prototyping workflows that skip standard governance to quickly validate ideas, reducing time-to-feedback and resource waste.

Core Features & Use Cases

  • Fast, isolated prototype development that yields a structured report and clear next steps.
  • Supports gate-driven decision workflow with memory-bank artifacts for future reference.
  • Useful for game concepts, product ideas, API contracts, and technology choices.

Quick Start

Invoke the prototype workflow by issuing /prototype [concept-description].

Frequently Asked Questions about prototype

FAQPage Schema
How do I validate a product idea through rapid prototyping without writing production code?

Rapid prototyping validates product ideas by turning them into isolated throwaway code and a structured report. This approach enforces isolation, avoids production code, and captures decisions in memory_bank through gated phases and review artifacts.

What is the best way to document API contracts during early concept exploration?

Documenting API contracts during concept exploration is best handled by generating a structured prototype report. This captures decisions in memory_bank artifacts and uses gate-driven workflows to record evaluation outcomes for future reference.

Can I use this workflow to prototype game concepts and technology choices?

Yes, you can prototype game concepts and technology choices using this workflow. It targets these specific areas by guiding rapid exploration, evaluation, and handoff through isolated development and structured decision-records.

How do I start the prototype workflow for a new concept?

To start the prototype workflow, invoke the command `/prototype [concept-description]`. This initiates the gate-driven process, generating throwaway code and a structured report with clear next steps for evaluation.

Why does rapid prototyping require gate checks and decision records?

Gate checks and decision records are required in rapid prototyping to maintain governance and reduce resource waste. They ensure isolated development phases are properly reviewed and captured in memory_bank artifacts for future reference.

What are the limitations of using throwaway code for prototype validation?

Throwaway code for prototype validation is strictly isolated and avoids production code entirely. This limitation ensures concepts are tested fast without architectural overhead, yielding a structured report and clear handoff steps rather than a deployable application.
