Mermaid Tools

Takes markdown files with embedded Mermaid diagrams and spits out numbered PNG images. The bundled script extracts all the diagram blocks, generates high-res PNGs (default 1200x800 at 2x scale), and has smart sizing that adjusts dimensions based on diagram type,timelines get wide and short, architecture diagrams get more pixels. You can crank up the scale factor for presentation or print quality. Built for WSL2 with Chrome/Puppeteer, though you'll need mermaid-cli and Python installed. Worth noting it bundles everything in a scripts directory and requires you to cd there first, which is a little clunky but makes the dependencies portable. Good if you're documenting systems and need actual images instead of hoping your viewer renders Mermaid correctly.
