zenuml

ZenUML

Use this skill alongside draw when the selected diagram type is zenuml.

Workflow

1. If the user already provided zenuml source, preserve its structure unless it is clearly invalid.
2. Otherwise, read references/language-guide.md before drafting new zenuml.
3. Draft the interaction in ZenUML syntax rather than Mermaid native sequenceDiagram syntax.
4. Run the packaged diagram draw CLI described in the draw skill.
5. If validation fails, repair the ZenUML once and run the draw CLI again.
6. Use the local files returned by the draw CLI, then follow the Diagramly.ai creation and authorization flow described in the draw skill.

Drafting rules

• Treat the official ZenUML docs linked in the reference file as the syntax ground truth.
• Use sequenceDiagram instead when the user explicitly asks for Mermaid native sequence syntax.
• Keep participants and message labels short.
• Prefer sync-style nesting when later steps depend on return values.
• Use async arrows for one-way notifications or events.
• Keep conditions code-like, not natural-language phrases.
