SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill eliminates the risk of committing to unproven software designs, state models, or UI layouts without first testing them, which often leads to costly rework and wasted development time after launch.

Core Features & Use Cases

  • Dual prototype branches: Routes to either an interactive terminal logic prototype for testing state machines and business logic edge cases, or a UI prototype for comparing multiple structurally distinct layout variations for a single page.
  • Use cases: Sanity-checking data model structures, validating API design before implementation, exploring UI layout options for new features, and testing state transition edge cases that are hard to reason about on paper.
  • Structured handoff process: Includes clear steps for capturing validated design decisions after prototyping, so insights are not lost when the throwaway prototype code is deleted.

Quick Start

Ask the AI to build a throwaway prototype to test your user state machine edge cases or generate 3 layout variants for your new settings page to compare before implementation.

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 design before writing production code?▼

You can validate a state machine by building a throwaway logic prototype to test state transition edge cases in an interactive terminal before committing to production implementation.

What is the best way to compare multiple UI layout variants for a new feature?▼

The best way to compare UI layouts is generating multiple structurally distinct variations for a single page within a UI prototype branch to evaluate design options before implementation.

How do I test business logic edge cases without setting up a database?▼

You can test business logic edge cases using an in-memory throwaway prototype that requires minimal setup and has no default persistence to avoid database configuration overhead.

How do I capture design decisions after testing a throwaway prototype?▼

You capture design decisions by following a structured handoff process after prototyping, ensuring validated insights are recorded before the throwaway prototype code is deleted.

Can I use throwaway prototypes to sanity-check data model structures?▼

Yes, you can use throwaway prototypes to sanity-check data model structures and validate API designs, preventing costly rework by identifying structural issues early before launch.

When should I not use throwaway prototype code for my project?▼

You should not use throwaway prototype code for persistent production data, as these in-memory prototypes intentionally lack default persistence and are designed to be deleted after validation.
