SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill allows you to quickly create throwaway prototypes to validate and refine your designs before committing to a final solution.

Core Features & Use Cases

Logic Prototype: Build a tiny interactive terminal app to explore and test state models and logic.
UI Prototype: Generate multiple UI variations for a single route, allowing you to visualize and compare design options.
Use Case: When you need to test a new feature's logic or UI design before implementation, this Skill helps you quickly visualize the concept and iterate on it.

Quick Start

Run the prototype with pnpm run prototype to interact with the logic or UI and explore different variations.

FAQPage Schema

How do I create a throwaway prototype to validate UI layouts?▼

To create a throwaway prototype for UI layouts, you can use this Skill to generate multiple UI variations for a single route, allowing you to quickly visualize and compare design options before committing to implementation.

How can I test state machine logic without building a full application?▼

You can test state machine logic by building a tiny interactive terminal app using this Skill, which provides an environment to explore and test state models and logic with minimal effort using local in-memory state.

What is the best way to explore UI design variations for a new feature?▼

The best way to explore UI design variations is to generate multiple variations for a single route within a throwaway prototype, allowing you to validate and refine your designs before committing to a final solution.

Do I need interactive terminal interaction to validate design logic?▼

Yes, validating design logic requires interactive terminal interaction. The Skill uses this terminal environment alongside local in-memory state to help you explore and test state models and logic efficiently.

How do I start prototyping once the environment is set up?▼

You start prototyping by running the command `pnpm run prototype` in your terminal. This will launch the interactive environment where you can immediately explore logic, state machines, and UI variations.

Can I use local in-memory state for testing state models?▼

Yes, you can use local in-memory state for testing state models. The Skill provides a throwaway environment that leverages in-memory state to help you explore and validate logic and UI designs interactively.
