SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It helps you validate UI, logic, and state-machine decisions before committing code, so you can catch wrong assumptions early and avoid costly rework.

Core Features & Use Cases

  • Throwaway by design: Creates minimal, clearly marked prototypes intended to be deleted or folded into real code after the question is answered.
  • Logic branch (state/business rules): Uses an interactive terminal app to drive a state model through hard-to-reason cases.
  • UI branch (visual variants): Generates multiple radically different UI variations on a single route, switchable via a URL search parameter, so you can compare structure and hierarchy.

Quick Start

Ask the AI to scaffold a prototype for your feature by choosing the logic branch if the question is about state transitions or data shape, otherwise choose the UI branch for competing visual layouts.

FAQPage Schema
How do I validate UI design variations before committing to final code?▼

You can validate UI design variations by generating throwaway prototypes that produce radically different visual layouts on a single route, switchable via a URL search parameter, allowing you to compare structure and hierarchy before committing.

What is the best way to test state machine transitions and data models?▼

The best way to test state machine transitions is using the logic branch, which uses an interactive terminal app to drive a state model through hard-to-reason cases and exposes full observable state after each change.

How do I scaffold a prototype for rapid state transitions or visual layout testing?▼

To scaffold a prototype, ask to generate one and select the logic branch for state transitions or data shape questions, or choose the UI branch for competing visual layouts to answer your specific design question.

When should I use throwaway prototypes for interactive terminal testing?▼

You should use throwaway prototypes for interactive terminal testing when you need to validate business-logic decisions or run state-machine sanity checks, ensuring the code is deleted or absorbed into production after results are captured.

Do I need to keep prototype code in my production codebase?▼

No, prototype code should not remain in your production codebase; prototypes are throwaway by design and must be deleted or folded into real code after the specific design or state question is answered.
