Excalidraw Skill

Step 0: Setup

Load companion skills when needed

• Drawing or styling a diagram → load excalidraw-design-guide (colors, sizing, anti-patterns)
• Building a multi-element diagram or reviewing one → must load excalidraw-workflow (planning, progressive drawing, review checklist)
• Mindmap or quality-sensitive visual request → must load both excalidraw-workflow and excalidraw-design-guide
• Just checking status, exporting, or a single command → no companion skills needed

Check if canvas is running

excalidraw status

Returns {"status":"healthy","timestamp":"...","elements_count":N,"websocket_clients":N} if running.
