Draw.io Diagram Skill

Write native .drawio files (mxGraphModel XML). Optionally export to PNG, SVG, or PDF via the desktop CLI — exported files embed the diagram XML so they remain editable in draw.io.

Workflow

1. Generate mxGraphModel XML for the requested diagram
2. Write to <name>.drawio in the working directory
3. If the user wants an export format, run the CLI with --embed-diagram, then delete the source .drawio
4. Open the result with open <file>

Check the user's request for a format preference:

• /drawio create a flowchart → flowchart.drawio
• /drawio png flowchart for login → login-flow.drawio.png
• /drawio svg: ER diagram → er-diagram.drawio.svg
• /drawio pdf architecture overview → architecture-overview.drawio.pdf

If no format is mentioned, write the .drawio file and open it.
