SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill eliminates the wasted effort of building full production features before validating if a design, data model, or user interface meets requirements, saving development time and reducing costly rework.

Core Features & Use Cases

  • Logic Prototyping: Build interactive terminal applications to test state machines, business logic, and data models against edge cases that are hard to reason about on paper.
  • UI Prototyping: Generate multiple radically different UI variations on a single route, toggleable via URL search parameters to compare design options quickly.
  • Use Case: If you are unsure if a login state machine handles expired sessions correctly, or want to test 3 different layout options for a settings page, this Skill lets you validate those choices in minutes instead of hours.

Quick Start

Ask the AI to prototype the new checkout flow's state logic to validate how it handles failed payment scenarios.

Frequently Asked Questions about prototype

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I validate a state machine or business logic before writing production code?

You can validate state machines and business logic by generating throwaway prototype terminal applications to test edge cases and data models against requirements before committing to full implementation.

What is the best way to compare multiple UI design variations for a single route?

Comparing UI design variations involves generating radically different UI options on a single route, toggleable via URL search parameters, allowing you to quickly evaluate design choices without full polish.

How do I test how a checkout flow handles failed payment scenarios?

Testing failed payment scenarios involves building interactive prototype logic to simulate the checkout flow, validating state transitions and edge case handling in minutes instead of hours.

Can I use throwaway prototypes to check if a login state machine handles expired sessions correctly?

Yes, throwaway prototype terminal applications can validate login state machines by simulating expired sessions and testing edge cases that are difficult to reason about on paper.

What are the limitations of using throwaway code for design exploration?

Throwaway prototype code has no persistence and minimal polish, with clear markers for eventual deletion or absorption into production code, making it unsuitable as a final production implementation.

Does prototyping data models require any specific dependencies or environment setup?

No specific dependencies are required; the Skill generates either runnable terminal applications for logic testing or toggleable UI route variations, requiring only a standard development environment to execute.
