draw.io Diagram Skill

1. Basic Rules

• Edit only .drawio files
• Always commit source .drawio; generated exports are disposable
• Do not directly edit generated .drawio.png, .drawio.svg, or .drawio.pdf files
• Prefer native mxGraphModel XML over Mermaid or CSV conversions
• Use descriptive lowercase filenames with hyphens (e.g., login-flow.drawio)
• Use auto-generated .drawio.png by pre-commit hook in slides

2. Output Formats
