Can I use this for UI state management?

Absolutely. The skill include XState patterns specifically designed for managing complex frontend application states and user interactions.

Does this skill support visual diagrams?

Yes, it generates state machine diagrams using PlantUML and Mermaid syntax for clear visualization of system behavior and transitions.

Which programming languages are covered for implementation?

The skill provides specific implementation patterns for C# (including the Stateless library and State Pattern) and TypeScript (using XState).

How does the documentation-first approach work?

It requires verifying state machine patterns and implementation standards before writing code, ensuring the logic aligns with project documentation.

What are Harel statechart semantics?

They are a standardized set of rules for statechart behavior, including hierarchy, concurrency, and communication, ensuring your designs are theoretically sound.

Designs and implements robust finite state machines and statecharts for complex system lifecycles and behavior specifications.

This skill provides comprehensive guidance for modeling entity lifecycles and system workflows using Harel statechart semantics. It enables developers to generate clear visual diagrams in PlantUML or Mermaid syntax and provides production-ready implementation patterns across languages like C# and TypeScript. Whether you are managing order processing, UI navigation, or complex backend workflows, this skill ensures your state transitions are logically sound, documented, and maintainable following industry best practices.
