Can this skill read my code to generate diagrams?

Yes, the skill can analyze your local source code to extract class names, methods, and relationships, then convert that information into a valid Mermaid diagram.

Can it update existing diagrams?

Yes, you can provide an existing Mermaid block and the skill can help you modify, expand, or fix errors in the syntax.

Is the output compatible with GitHub?

Absolutely. It generates standard Mermaid syntax which is natively supported and rendered by GitHub, GitLab, and many other modern documentation platforms.

What is a Mermaid class diagram?

A Mermaid class diagram is a visual representation of the relationships and structures within an object-oriented system, rendered via the text-based Mermaid.js syntax.

Do I need to know Mermaid syntax to use this?

No, this skill handles the syntax generation for you. You can describe your architecture in plain English or point to your code, and the skill will write the Mermaid code.
