SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The Prototype skill helps you quickly answer design or logic questions before committing to production code, reducing wasted effort and uncertainty.

Core Features & Use Cases

  • Logic prototypes: Build a tiny interactive terminal app to explore state machines, business rules, or hard-to-reason-about flows.
  • UI prototypes: Create multiple radically different interface variants on a single route so design choices can be compared quickly.
  • Use case: If you are unsure whether a workflow should be modeled one way or another, this skill helps you build a disposable prototype that surfaces the full state after each interaction.

Quick Start

Use the prototype skill to build a throwaway prototype for this feature and choose the logic or UI branch based on the question being tested.

FAQPage Schema
How do I test a state machine before writing production code?

You can build a terminal-based logic prototype to interactively inspect state transitions and business rules. This throwaway approach surfaces the full state after each action, letting you validate complex state machine flows before committing to production implementation.

What is a throwaway prototype for design exploration?

A throwaway prototype is a disposable implementation built to answer specific UI or logic questions. It renders multiple radically different interface variants on a single route so you can rapidly compare alternative design approaches without investing in production code.

Can I compare multiple UI variations on the same route?

Yes, by selecting the UI branch, the prototype renders multiple radically different interface variants on a single route. This enables rapid comparison of alternative interface approaches so you can evaluate design choices quickly before finalizing your implementation.

How do I explore business rules without setting up a full application?

Build a tiny interactive terminal app using the logic prototype branch. This allows you to explore business rules and hard-to-reason-about flows by surfacing the complete application state after each interaction, avoiding the need for full application setup.

When should I use throwaway prototypes instead of production code?

Use throwaway prototypes when you are unsure how to model a workflow or need to test state machines, business rules, or UI designs. They reduce wasted effort by answering design and logic questions before you commit to production implementation.

Do I need any dependencies to build a prototype for logic or UI testing?

No dependencies are required to build a prototype. You can immediately select either the terminal-based logic branch for state inspection or the route-based UI branch for rendering interface variations without installing external dependencies.
