Summary
This is your reference guide when Claude needs to generate PlantUML diagrams. It covers 15+ diagram types from sequence and class diagrams to C4 architecture and even JSON visualization. The skill uses progressive disclosure, keeping common syntax in the main file and deferring to detailed references for complex cases like swimlanes or C4 includes. Smart move since PlantUML syntax is dense and context-specific. If you're building documentation tools or need Claude to output diagrams as code, this handles the syntax lookups so you don't have to paste examples every time. Includes test scenarios for authentication flows and domain modeling.
