Can I view diagrams directly in my terminal?

Yes, by using the --ascii or -a flag with the render script, the skill will output a text-based diagram optimized for terminal display.

Can I use this skill to render existing .mmd files?

Absolutely. You can pass the file path of any .mmd file to the --input option to render it into an SVG or ASCII format.

How do I install the beautiful-mermaid dependency?

The skill automatically checks for the library in your package.json. If missing, it will prompt you to install it via npm, bun, or pnpm.

Which themes are available for SVG rendering?

The skill supports multiple themes including Tokyo Night, Zinc Light, and Zinc Dark. You can specify these using the --theme flag.

Does it support standard Mermaid syntax?

Yes, though the underlying beautiful-mermaid parser requires clean formatting, such as newlines between statements and spaces around arrows (A --> B).
