Diagramming

mermaid-diagrams is a practical Mermaid reference for flowcharts, sequence diagrams, class diagrams, ERDs, C4, and architecture diagrams. Use it to choose the right diagram type, follow the repository references, and create versionable docs-friendly diagrams with better prompts and renderer-aware syntax.

excalidraw is a workflow skill for explaining, updating, and creating Excalidraw diagrams by delegating noisy .excalidraw JSON to subagents. Use it for architecture diagrams, flowcharts, and diagram-aware tasks without bloating the main agent context.
