SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill solves the problem of over-engineering or committing to unproven designs by providing a structured, throwaway environment to test business logic or UI variations before they are integrated into the main codebase.

Core Features & Use Cases

Logic Prototyping: Build interactive terminal applications to stress-test state machines and business logic against edge cases.
UI Exploration: Generate multiple UI variants on a single route to visually compare layouts and information hierarchies.
Use Case: When unsure if a complex state machine handles specific edge cases, use this skill to build a TUI that allows you to manually trigger transitions and observe state changes in real-time.

Quick Start

Use the prototype skill to create a new logic prototype for the current state machine by running the scaffold command in your terminal.

FAQPage Schema

How do I validate business logic before committing to a production design?▼

Generate throwaway code artifacts within an isolated, memory-only environment to empirically test business logic and state machines. This prevents over-engineering by validating designs before production implementation.

Can I test state machine edge cases using a terminal app?▼

Yes, you can build interactive terminal applications to stress-test state machines. This allows you to manually trigger transitions and observe state changes in real-time to verify edge case handling.

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

Generate multiple UI variants on a single route to visually compare layouts and information hierarchies. This throwaway approach lets you evaluate interface designs via swappable URLs before production integration.

Do I need a task runner to prototype logic in an isolated environment?▼

Yes, a project-specific task runner is required to execute the prototype. It ensures the throwaway code runs in an isolated, memory-only environment to prevent any impact on your main codebase.

When should I use throwaway code for prototyping instead of building directly in my codebase?▼

Use throwaway code when unsure if a complex state machine handles edge cases or when exploring UI layouts. It provides a structured environment to test unproven designs before integrating them into your main codebase.
