Create, render, inspect, refine, and restyle PlantUML diagrams as editable .puml source plus PNG or SVG. Use for sequence, class, component, deployment, activity or flowchart, state, use-case, ER or database, C4 or architecture, mind-map, and Gantt diagrams; for diagrams derived from source code; for PlantUML fenced blocks or linked .puml files in Markdown; and when a system explanation with several interacting components, APIs, data flows, or type relationships benefits from a diagram. Prefer local rendering and never upload source to Kroki without explicit user approval.
