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.

When To Use / Diagnostic Intake

适用于业务流程、消息集成或价值流示意。先确认角色、开始/结束事件、异常路径、等待条件，以及用户是否需要可执行流程模型。

Workflow

逐条列出正常与异常路径→选择 BPMN/EIP/Lean 图形→设置角色边界→核对分支汇合→生成并渲染 PlantUML。

Tools and Dependencies

依赖支持本包 stencil 的 PlantUML。图形输出不是 BPMN 2.0 执行文件；需要执行语义时明确后续建模接口。

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.

Mxgraph Stencil Syntax

mxgraph.<library>.<icon> "Label" as <alias>

BPMN Stencil Family (mxgraph.bpmn.*)

Events — Circle shapes for process triggers and outcomes:

Gateways — Diamond shapes for branching/merging:

Tasks — Use rectangle for tasks, stencil markers for typed tasks:

Data — Document-like shapes:

EIP Stencil Family (mxgraph.eip.*)

Lean Mapping Stencil Family (mxgraph.lean_mapping.*)

Connection Types

Quick Example

@startuml
left to right direction

mxgraph.bpmn.event.start "Start" as start
rectangle "Review\nRequest" as review
mxgraph.bpmn.gateway2.exclusive "Approved?" as gw
rectangle "Process\nOrder" as process
rectangle "Notify\nRejection" as reject
mxgraph.bpmn.event.end "End" as end_ok
mxgraph.bpmn.event.end "End" as end_fail

start --> review
review --> gw
gw --> process : "Yes"
gw --> reject : "No"
process --> end_ok
reject --> end_fail
@enduml

Diagram Types

Capability Upgrade

Mode Selection

• Quick: 把文字流程转成基础 BPMN。
• Standard: 补齐泳道、事件、网关、任务、异常路径和消息流。
• Deep: 结合角色职责、系统边界、审批规则、SLA 和异常场景，形成流程优化或自动化设计图。

Process Modeling Logic

先确定流程边界、开始/结束事件、参与角色和关键决策点。没有明确事件和责任人的流程不应直接画成最终 BPMN。

Quality Gates

• 每个泳道对应真实角色、部门或系统。
• 网关条件互斥且完整。
• 异常、退回、超时和取消路径已处理。
• 消息流和顺序流没有混用。
• 输出包含图和流程说明，便于业务复核。
