Excalidraw Skill

Step 0: Detect Connection Mode

Before doing anything, determine which mode is available. Run these checks in order:

Check 1: MCP Server (Best experience)

mcp-cli tools | grep excalidraw

If you see tools like excalidraw/batch_create_elements → use MCP mode. Call MCP tools directly.

Check 2: REST API (Fallback — works without MCP server)

curl -s http://localhost:3000/health

If you get {"status":"ok"} → use REST API mode. Use HTTP endpoints (curl / fetch) from the cheatsheet.
