SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill removes the uncertainty of building complex features by allowing you to quickly sanity-check state models, business logic, or UI layouts before committing to production code.

Core Features & Use Cases

  • Logic Prototyping: Build interactive terminal-based state machines to test edge cases in business logic or data models.
  • UI Prototyping: Generate multiple structural UI variations on a single route to compare layouts and information hierarchies.
  • Use Case: You are unsure if a complex state machine handles a specific sequence of user actions correctly; use this Skill to build a throwaway TUI that lets you manually trigger transitions and observe state changes in real-time.

Quick Start

Use the prototype skill to create a new logic prototype for the user authentication state machine.

FAQPage Schema
How do I validate a state machine's logic before writing production code?▼

You can validate state machine logic by building interactive terminal-based state machines as throwaway code. This allows you to manually trigger transitions and observe state changes in real-time to test edge cases.

What is the best way to compare multiple UI layout variations during design?▼

UI prototyping allows you to generate multiple structural UI variations on a single route. This helps compare layouts and information hierarchies within your existing project structure before committing to a design.

How do I test architectural decisions quickly without affecting my main project?▼

You can create throwaway code using a task runner to execute isolated, in-memory modules. This simulates production logic and interface layouts to rapidly sanity-check architectural decisions without impacting your codebase.

Can I simulate business logic edge cases using terminal-based interfaces?▼

Yes, you can build a throwaway TUI to manually trigger transitions and observe state changes in real-time. This interactive terminal-based state machine approach tests specific sequences of user actions for edge cases.

Do I need a task runner to execute isolated prototype modules?▼

Yes, a task runner is required to execute isolated, in-memory modules that simulate production logic or interface layouts. This ensures your throwaway code runs independently within your existing project structure.
