SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill allows you to quickly create throwaway prototypes for your logic or UI design, providing a lightweight terminal app for testing and iterating on ideas.

Core Features & Use Cases

  • Logic Prototyping: Create a simple terminal app to manually test and visualize state models and business logic.
  • UI Prototyping: Generate different UI variations on a single route, switchable from a floating bottom bar.
  • Use Case: When you need to explore different UI options for a page or understand the implications of a new feature without writing full production code.

Quick Start

Use the prototype skill to test the state transitions of your user authentication flow.

FAQPage Schema
How do I test a state machine without writing full production code?

You can test a state machine by generating a throwaway terminal app to manually visualize and validate state transitions. This lightweight prototyping approach isolates logic testing from your main application codebase.

What is the best way to prototype UI variations for a single route?

Prototyping UI variations is best done by generating different designs on a single route, switchable from a floating bottom bar. This allows quick iteration on UI design concepts without full integration.

Can I use a terminal app to manually test business logic?

Yes, you can use a terminal app to manually test and visualize business logic. It creates a dedicated environment for exploring feature implications before committing to production implementation.

Do I need external dependencies to prototype logic in my development environment?

No, you do not need external dependencies to prototype logic. This Skill operates entirely within your development environment to provide a lightweight terminal app for immediate testing.

When should I use a throwaway prototype instead of building a permanent feature?

Use a throwaway prototype when you need to explore different UI options or understand the implications of a new feature. It allows quick iteration without the overhead of writing full production code.

Does logic prototyping work for testing user authentication flows?

Yes, logic prototyping works for testing user authentication flows by creating a simple terminal app. You can manually trigger and verify state transitions throughout the authentication lifecycle.
