UML Diagram Generator

Quick Start: Choose diagram type → Define classes/objects/actors → Add relationships/edges → Use appropriate shapes and arrow styles → Wrap in ```drawio fence.

⚠️ IMPORTANT: Always use ```drawio code fence. NEVER use ```xml — it will NOT render as a diagram.

Critical Rules

🔗 This is a drawio-derived skill. All structure, layout, and edge routing rules inherit from drawio SKILL.md. Read the base rules first.

UML-specific additions:

• Use standard UML shapes: shape=umlLifeline, shape=umlActor, shape=component, swimlane;childLayout=stackLayout
• Use fillColor=none; for package/component containers to avoid covering child elements
