SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It helps you quickly test whether a state model or user interface design makes sense before you commit to building it.

Core Features & Use Cases

  • Throwaway design validation: Rapidly prototype either business logic/state transitions or UI layout variations.
  • State transparency while iterating: Surface the full relevant state after each action (logic) or variant switch (UI) so problems appear immediately.
  • Two targeted branches: Use a logic terminal prototype for edge cases in data shape and state machines, or a UI variant switcher for radically different interface options on the same route.

Quick Start

Ask for a prototype, then choose the branch by intent: use the logic terminal prototype when you need to sanity-check state transitions and data shape, or use the UI variant prototype when you need to explore what a screen should look like.

FAQPage Schema
How do I validate state machine logic and data model edge cases before writing production code?

A UI variant prototype lets you explore radically different interface options on the same route by switching between variants in a single command. It keeps logic portable and surfaces the full state immediately after each variant switch so layout problems appear instantly.

What's the best way to prototype multiple UI layout variants for the same screen route?

A UI variant prototype lets you explore radically different interface options on the same route by switching between variants in a single command. It keeps logic portable and surfaces the full state immediately after each variant switch so layout problems appear instantly.

When should I use throwaway prototypes instead of building production features?

Use throwaway prototypes when you need to validate software designs, such as state transitions or interface layouts, before committing to production. Once the design question is answered, you throw away or absorb the results rather than maintaining the prototype code.

How do I start prototyping logic and UI variants for design validation?

Ask for a prototype and choose your branch based on intent: use a logic terminal prototype to sanity-check state transitions and data shapes, or use a UI variant prototype to explore what a screen should look like. The prototype runs in-memory with one command.

Can I run a state machine prototype in-memory to see state changes after every action?

Yes, the logic terminal prototype runs in-memory and surfaces the full relevant state after each action. This state transparency while iterating ensures that data shape and state machine edge cases appear immediately without requiring external dependencies.
