Mermaid Skill
Use this skill to quickly validate Mermaid diagrams by parsing + rendering them with the official Mermaid CLI.
Prerequisites
- Node.js + npm (for
npx). - First run downloads a headless Chromium via Puppeteer. If Chromium is missing, set
PUPPETEER_EXECUTABLE_PATH.
Tool
Validate a diagram
./tools/validate.sh diagram.mmd [output.svg]
- Parses and renders the Mermaid source.
- Non-zero exit = invalid Mermaid syntax.
- Prints an ASCII preview using
beautiful-mermaid(best-effort; not all diagram types are supported). - If
output.svgis omitted, the SVG is rendered to a temp file and discarded.
Workflow (short)
- If the diagram will live in Markdown: draft it in a standalone
diagram.mmdfirst (the tool only validates plain Mermaid files). - Write/update
diagram.mmd. - Run
./tools/validate.sh diagram.mmd. - Fix any errors shown by the CLI.
- Once it validates, copy the Mermaid block into your Markdown file.
