SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you resolve uncertainty about business logic, state transitions, or UI structure by turning a vague idea into a quick, throwaway artifact you can interact with.

Core Features & Use Cases

  • Logic prototyping: Build a tiny interactive terminal app that drives an in-memory state model and exposes edge cases you can’t reliably reason about on paper.
  • UI prototyping: Generate several radically different UI variants for the same route, switchable via a URL search parameter to compare structure and hierarchy.
  • Design decision capture: Preserve the answer (the validated choice and the question it solved) in a durable place before deleting the rest.

Quick Start

Ask to prototype your idea and specify whether you want it as a logic/state terminal experiment or as UI route variants, then run the Skill in a single command from its project task runner.

FAQPage Schema
How do I sanity-check business logic edge cases before writing real code?

To sanity-check business logic edge cases, build a tiny interactive terminal app that drives an in-memory state model, exposing transitions you cannot reliably reason about on paper before committing.

What is the best way to compare multiple UI variants for the same route?

The best way to compare multiple UI variants is generating radically different layouts for the same route, switchable via a URL search parameter to evaluate structure and hierarchy quickly.

How do I create a throwaway prototype to validate design decisions quickly?

To validate design decisions quickly, create a throwaway prototype with a minimal runnable entry command and clear state surfacing after each action, then delete or absorb the results once the answer is captured.

Can I run a state machine prototype in memory without persisting data?

Yes, you can run a state machine prototype entirely in memory without persisting data, using a minimal runnable entry command to drive the interactive model and surface state changes after each action.

When should I avoid using throwaway code for interactive prototyping?

You should avoid using throwaway code for interactive prototyping if you need persistent data storage or production-ready architecture, as this approach relies on in-memory, non-persistent implementations meant for quick validation only.

Do I need a project task runner to use this prototyping approach?

Yes, you need a project task runner because the throwaway prototype requires running the Skill in a single command from its project task runner to execute the minimal runnable entry point.
