SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill eliminates the risk of committing to untested business logic, state machines, data models, or UI designs that have uncaught edge cases or fail to meet user needs, saving development time and avoiding costly rework after full implementation.

Core Features & Use Cases

  • Interactive Logic Prototypes: Build a lightweight terminal app to drive state machines, business logic, and data models through real input scenarios to catch edge cases that are impossible to spot on paper.
  • Multi-Variant UI Prototypes: Generate 3+ structurally different UI layout variations for a page or component, switchable via a floating bottom bar, to compare information hierarchy and affordances before selecting a final design.
  • Use Case: If you are unsure if your order state machine correctly handles the edge case of a user canceling an order after payment but before shipping, use the logic prototype to test the scenario. If you cannot decide between a card grid, sidebar layout, or list view for your dashboard, use the UI prototype to toggle between all three directly in the browser.

Quick Start

Ask the AI to build a throwaway prototype to test whether your user permission state machine handles the edge case of a role being revoked mid-session, or to generate three different layout variations for your settings page to compare in the browser.

Frequently Asked Questions about prototype

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

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

You can validate business logic by building a throwaway terminal-based state driver. This interactive prototype allows you to run real input scenarios and catch edge cases in state transitions before committing to full implementation.

What is the best way to compare multiple UI layout options for a web page?▼

The best way to compare UI layout options is to generate a route-mounted multi-variant UI switcher. It provides a floating development-only control bar to toggle between different structures and compare information hierarchy directly in the browser.

How do I validate a data model and business logic without setting up a full database?▼

You can validate data models and business logic without a database by building a lightweight interactive prototype. It operates with no persistence by default and marks all code as disposable, allowing you to sanity-check data shapes quickly.

Can I use rapid prototyping to test untested business logic without affecting my production app?▼

Yes, you can use rapid prototyping to test untested business logic in isolation. The prototype generates disposable code gated behind a development-only floating control bar, ensuring it does not affect your production application.

When should I avoid using throwaway code for UI design validation?▼

You should avoid using throwaway code for UI design validation when you need persistent state or production-ready components. The prototypes are designed as disposable code with no default persistence, making them unsuitable for final implementation.
