Business Process & Integration Diagram Generator

Quick Start: Choose diagram type → Declare stencil icons for events/gateways/tasks → Group into pools/lanes → Connect with arrow syntax → 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 left to right direction for process flows (start→end reads left-to-right)
Use mxgraph.bpmn.* for BPMN events, gateways, and task markers
Use mxgraph.eip.* for Enterprise Integration Pattern icons
Use mxgraph.lean_mapping.* for Value Stream Mapping symbols
Default colors are applied automatically — you do NOT need to specify fillColor or strokeColor
Use rectangle "Pool" { ... } for BPMN pools and lanes
Sequence flows use -->, message flows use ..> (dashed)

Full stencil reference: See stencils/README.md for 9500+ available icons.
