## Rules for an agent

- Open source (MIT, github.com/excalidraw/excalidraw) with an official npm package @excalidraw/excalidraw (React component plus export helpers) and @excalidraw/mermaid-to-excalidraw; the repo ships a Dockerfile for self-hosting; there is no HTTP API, so generate .excalidraw JSON scenes or use the official MCP server.
- Keep the MIT copyright notice when bundling the editor code
- Embed the editor with the npm package rather than iframing excalidraw.com (the terms forbid unauthorized framing)
- Do not scrape the site
