This skill enables Claude to architect and document software systems through standardized UML modeling. It supports a wide range of structural and behavioral diagrams, including class, sequence, activity, and state machine diagrams, using industry-standard PlantUML and Mermaid syntax. By following a documentation-first approach based on the UML 2.5 specification, it helps developers visualize complex interactions, plan system designs, and maintain high-quality technical documentation directly within their coding workflow.
