bpmn

bpmn is a skill for Claude Code, Codex from guoliang1114-boop/AriaAI. It costs 43 tokens per session (2,557 once invoked), scanned A, original, MIT.

A diagram-writing skill for showing business workflows, message-based integrations, and value streams in PlantUML, a text format that renders as diagrams.

In plain words
What is it for?
Use it to map approval chains, automation workflows, integration patterns, and how value moves through a process.
Why use it?
It removes the need to remember the correct symbols and syntax for process diagrams, including events, decisions, tasks, pools, lanes, and message flows.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

bpmn scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 216 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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:

Icon Meaning
mxgraph.bpmn.event.start Start Event
mxgraph.bpmn.event.end End Event
mxgraph.bpmn.event.terminateEnd Terminate End
mxgraph.bpmn.event.timerStart Timer Start
mxgraph.bpmn.event.timerCatching Timer Intermediate
mxgraph.bpmn.event.messageStart Message Start
mxgraph.bpmn.event.messageCatching Message Catching
mxgraph.bpmn.event.messageEnd Message End
mxgraph.bpmn.event.errorEnd Error End
mxgraph.bpmn.event.errorBound Error Boundary

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
