GitHub SKILL.md

What it does

Render Mermaid diagram source (.mmd) into high-quality SVG for web/docs or ASCII art for terminal/READMEs. Includes theming, templates, batch processing, and options for transparent backgrounds and custom fonts. Useful for generating visuals for docs, presentations, and developer workflows.

When to use it

When a user asks to render or beautify a Mermaid diagram
To batch-convert a directory of .mmd files into SVG/ASCII
When you need themed, presentation-ready diagrams or terminal-friendly ASCII output

What's included

Scripts: rendering and batch scripts (render.mjs, batch.mjs, themes.mjs)
References: DIAGRAM_TYPES.md, THEMES.md, api_reference.md (documentation in references/)
Instructions: quick-start examples for single-file rendering, batch runs, theming, and troubleshooting guidance for invalid syntax or missing dependencies

Compatible agents

Best fit for developer/code-capable agents and environments that can run Node.js scripts (Copilot/Codex-style agents, Claude/Code agents, local CLI-based automation).

Audit Summary

Pretty Mermaid renders Mermaid diagrams to SVG or ASCII with theming support. Scripts were skipped during execution — they require the beautiful-mermaid npm package which auto-installs on first run. SKILL.md is well-documented with clear triggers, workflow decision trees, and troubleshooting. Main security concern is auto-installing npm packages without user confirmation.

Watch Out

Auto-installs beautiful-mermaid npm package on first run without explicit user consent
Scripts require Node.js and npm to be available
Batch script needs .mmd files in input directory

Missing Dependencies

beautiful-mermaid

Notes

Auto-install of npm dependency via execSync('npm install') reduces security score. Scripts are well-structured but couldn't be tested due to missing dependency. The skill follows a clean architecture pattern with proper separation of concerns.
