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.
