Excalidraw diagrams

Use Excalidraw when the learner needs to inspect a spatial relationship: what connects, contains, changes state, or crosses a boundary. The selected subject guide decides what must be true in the picture. This guide decides how to draw and check it. A diagram should answer one question, not decorate a lesson.

Load only the instructions you need

1. Read this page before using the excalidraw MCP server.
2. Read color and type for every diagram. Set the meaning of each color and the label hierarchy before drawing.
3. Read the relevant pattern in diagram types for the relation in the lesson brief. Combine patterns only when the claim requires it.
4. Read review and handoff before sending the result to the lesson coordinator.

The link to this page loads guidance only. A selected Excalidraw block is produced by calling the excalidraw MCP server's read_me and create_view tools, then inspecting the returned scene.

Keep the diagram's terms, symbols, units, arrow direction, and color meanings identical to the surrounding explanation and exercises. If the brief does not specify these, establish them from the active lesson.

Build the scene

1. Write the claim in one sentence: “A learner can see that …”. List the objects and the relation needed to support that claim.
2. Call read_me before the first create_view in a task, unless its current element format is already in context. Its schema is authoritative; do not guess field names, fonts, export commands, or link format.
3. Sketch the reading order and choose a camera that makes labels readable at the inline viewport. Place boundaries behind the objects they contain.
4. Call create_view with the schema returned by read_me. Draw in the order the learner should encounter the idea. Keep a final overview in frame.
5. Open the rendered view and perform the checks in review and handoff. Revise a specific defect; stop when the relation is accurate and legible.

If the server fails, make one correction based on its error. If it remains unavailable, use prose, a table, Mermaid, or a runnable trace and tell the coordinator what was substituted. Do not claim an Excalidraw view or ready artifact without an inspected result.
