workflow-bpmn-validator

workflow-bpmn-validator is a skill for Claude Code, Cursor from aborroy/aiup-alfresco. It costs 0 tokens per session (1,280 once invoked), scanned A, original, Apache-2.0.

A checker for Alfresco Activiti BPMN 2.0 workflow files and their companion form models. BPMN is a standard XML format for drawing and running business processes, such as tasks assigned to people or groups.

In plain words
What is it for?
Use it to validate workflow process XML and related model XML before deployment. It checks namespaces, process settings, task assignments, variables, forms, and unsupported class references.
Why use it?
It finds structural mistakes that can stop a workflow from running or leave tasks without anyone able to claim them. It also flags patterns from Flowable, a different workflow engine, that are not supported by the stated Alfresco version.

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

workflow-bpmn-validator 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 9d 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.

Workflow BPMN Validator

Validate the given Alfresco Activiti BPMN process definition (and companion workflow model, if present) against these rules.

BPMN Namespace Validation

  • Root element must be <definitions> with BPMN 2.0 namespace: xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL"
  • REQUIRED: xmlns:activiti="http://activiti.org/bpmn" — must be present; Alfresco Activiti extensions use this namespace
  • ERROR if present: Any org.flowable.* class reference in class attributes of <activiti:taskListener>, <activiti:executionListener>, or <serviceTask activiti:class="...">. ACS 26.1 uses Activiti 5.22.x; the Flowable API is not on the classpath.

Process Structure Validation

  • <process> element must have:
    • id attribute (camelCase identifier)
    • name attribute (human-readable)
    • isExecutable="true"
  • WARNING if any <startEvent> is missing activiti:formKey in a non-trivial process (more than one user task)
  • Every <userTask> must have either activiti:assignee or activiti:candidateGroups:
    • WARNING if a user task has neither — it will never be claimable
    • WARNING if a user task that represents an approval step is missing activiti:formKey
  • Every <exclusiveGateway> with multiple outgoing sequence flows must have <conditionExpression> on all but one outgoing flow:
    • ERROR if an outgoing flow from an exclusive gateway has no condition and is not marked as default
  • Every <serviceTask> must have either activiti:class or activiti:expression or activiti:delegateExpression:
    • WARNING for service tasks with none of these attributes (becomes a no-op)

Variable Naming Validation

  • Scan all <activiti:string> blocks inside <activiti:field name="script"> elements and inside <conditionExpression> elements
  • ERROR if any call to execution.setVariable(...) or task.getVariableLocal(...) uses a variable name containing a colon (e.g. acme:outcome). The correct form uses underscore (acme_outcome). Alfresco maps content model properties {prefix}wf:{propName} → process variable {prefix}wf_{propName} (colon → underscore).
  • ERROR if any <conditionExpression> references a variable with a colon in the name (e.g. ${acme:count == 2}). Use ${acme_count == 2}.
