What this skill does
Draw.io Diagram Skill Generate draw.io diagrams as native .drawio files and export them to PNG images that can be embedded in Word documents. How to Create a Diagram 1. Generate draw.io XML in mxGraphModel format for the requested diagram 2. Write the XML to a .drawio file using the create/edit file tool 3. Export to PNG using the bundled export script Bundled Export Script This skill includes drawio-to-png.mjs, a Node.js export script with two rendering backends: 1. draw.io CLI (pixel-perfect, fastest) — used automatically if draw.io desktop is installed 2. Official draw.io viewer in headless browser (pixel-perfect, needs Chromium/Edge) — fallback when CLI is unavailable Usage Skill Folder Contents File Purpose ------ --------- SKILL.md This instruction file scripts/drawio-to-png.mjs Node.js export script (CLI + browser fallback) scripts/package.json Dependencies (puppeteer-core) Supported Export Formats Format Embed XML Notes -------- ----------- ------- png Yes Viewable everywhere, editable in draw.io svg Yes Scalable, editable in draw.io pdf Yes Printable, editable in draw.io Draw.io XML Style Conventions Use these styles for consistent, professional diagrams: Locating the draw.io CLI Try drawio first (works if on PATH), then fall back: Windows: "C:\Program Files\draw.io\draw.io.exe" macOS: /Applications/draw.io.app/Contents/MacOS/draw.io Linux: drawio (via snap/apt/flatpak) CLI Export Command Flags: -x (export), -f (format), -e (embed diagram XML), -b (border), -o (output path).
