FAQPage Schema
How do I generate a Mermaid diagram from a natural language description?

To generate a Mermaid diagram from natural language, you simply provide a description of your system or code, and the skill returns a ready-to-paste Mermaid diagram block. It automates diagram creation by enforcing syntax rules and type mappings.

Can I create architecture visualizations by analyzing existing code and documentation?

Yes, you can create architecture visualizations by providing your existing code and documentation. The skill analyzes these inputs to automatically produce Mermaid diagrams suitable for software design and documentation workflows.

What diagram types are supported for software design and documentation workflows?

Supported diagram types for software design and documentation workflows include graph, flowchart, sequence, class, and state diagrams. The skill allows quick switching between these multiple formats while enforcing proper Mermaid syntax.

Does the generated Mermaid syntax need manual validation before pasting into documentation?

No, manual validation is not needed because the skill enforces Mermaid syntax rules and formatting automatically. It validates the syntax during generation to ensure you receive clean, ready-to-paste diagram blocks for your documentation.

What is the best way to switch between flowchart and sequence diagrams for the same system?

The best way to switch between flowchart and sequence diagrams is to use the skill's built-in quick switching feature. It maps your natural language description to different diagram types while maintaining Mermaid syntax rules.
