Excalidraw Diagram Generator skill
Generates production-quality architecture diagrams, system designs, and data flow visualizations from natural language. Includes a Playwright-based self-validation pipeline: generates Excalidraw JSON, renders to PNG, reviews its own output for layout issues, and fixes problems before presenting results.
Why it matters
Diagrams survive longer than conversations. An agent that generates publishable architecture diagrams closes the documentation gap every fast-moving team has.
