FAQPage Schema
How do I render Mermaid diagrams inline within a terminal?▼

To render Mermaid diagrams inline, this Skill converts Mermaid syntax into PNG format and displays the images directly within compatible terminals like iTerm2 or Ghostty for rapid visual iteration.

Do I need mermaid-cli to visualize flowcharts in iTerm2?▼

Yes, you need the mermaid-cli (mmdc) package to generate the PNG images, alongside terminal-specific viewers like 'imgcat' or 'kitten icat' to facilitate the inline display of those flowcharts.

What is the best way to rapidly iterate on sequence diagrams without leaving the command line?▼

The best way to iterate on sequence diagrams from the command line is to use this Skill, which automates rendering Mermaid syntax into PNG images and displays them instantly after each modification.

Can I visualize Mermaid syntax in terminals other than iTerm2 and Ghostty?▼

For terminals other than iTerm2 and Ghostty, inline display may not be supported, but the Skill provides a fallback mechanism to automatically open the rendered PNG image file instead.

Does this inline rendering approach work for state charts and other complex diagram types?▼

Yes, the inline rendering approach supports visualizing state charts and other complex Mermaid diagram types by converting the syntax into PNG format for immediate review within your terminal environment.
