About Excalidraw Diagram Skill
This skill has the agent write .excalidraw JSON for workflows, architectures and concepts, with an emphasis on diagrams that explain an idea rather than just list components.
It includes a renderer setup so the agent can check its own output, and the hand-drawn Excalidraw look works well in READMEs, talks and threads.
