SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Helps you test an idea before committing to production code by turning an unclear product question into a small throwaway prototype. It is meant for moments when you need to verify whether a state model, flow, or layout actually feels right.

Core Features & Use Cases

  • Logic prototypes: Build a tiny interactive terminal app to exercise state transitions, edge cases, and data shape questions.
  • UI prototypes: Create several structurally different variants on a single route so users can compare layouts, hierarchy, and interaction patterns.
  • Use case: A team can quickly validate a dashboard layout, settings screen, or business rule before investing in a full implementation.

Quick Start

Ask the assistant to prototype the idea using the appropriate branch and make it runnable in one command.

FAQPage Schema
How do I prototype a state machine to test edge cases before writing production code?

To prototype a state machine, you build a tiny interactive terminal app to exercise state transitions and probe edge cases. This throwaway model verifies your logic handles data shape questions correctly before you commit to a real build.

What is the best way to compare UI layout variants for a dashboard route?

The best way to compare UI layout variants is to create multiple structurally different variants on a single route with minimal polish. This lets you directly compare layouts, hierarchy, and interaction patterns to validate which design feels right before full implementation.

Can I use throwaway prototypes to validate business logic and data models?

Yes, you can use throwaway prototypes to validate business logic and data models. They turn an unclear product question into a small interactive terminal model, allowing you to probe data shapes and rules before investing in full implementation.

How do I make a prototype runnable in one command?

You make a prototype runnable in one command by asking the assistant to generate it using the appropriate branch. The prototype must be placed clearly as a throwaway file and execute immediately without complex setup or configuration.

Does prototyping UI variants require high-fidelity design polish?

No, prototyping UI variants requires minimal polish. The focus is on comparing structurally different layouts, hierarchy, and interaction patterns to answer implementation questions, rather than producing polished, production-ready interface designs.

When should I not use throwaway prototypes for product exploration?

You should not use throwaway prototypes when you need production-ready code or high-fidelity UI polish. They are designed strictly for answering product or implementation questions by comparing alternatives, not for final deliverable builds.
