UML Diagram Generator

Quick Start: Choose diagram type → Write PlantUML text → Define elements and relationships → Wrap in ```plantuml fence.

⚠️ IMPORTANT: Always use ```plantuml or ```puml code fence. NEVER use ```text — it will NOT render as a diagram.

Critical Rules

• Every diagram starts with @startuml and ends with @enduml
• Use standard PlantUML keywords: class, interface, abstract, enum, actor, participant, component, node, database, package
• Relationships use arrow syntax: -->, <|--, *--, o--, ..>, ..|>
• Use skinparam for global styling and colors
• Use #color on individual elements for specific colors
• Notes use note left of, note right of, note over, or standalone note "text" as N
