diagramming-skill

Create diagrams, mind maps, flowcharts, architecture sketches, and relationship graphs. Trigger on simple Chinese requests like "帮我画个结构图", "帮我画个脑图", "画个脑图", "画个关系图", as well as diagram, mindmap, Mermaid chart, flowchart, sequence diagram, or dependency graph. Default to Mermaid as the primary text-based format and produce local files. Use local Excalidraw only when the user explicitly wants a hand-drawn whiteboard style or interactive editing.
