Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| room_id | string | no | Room ID of an existing canvas to add to. If the user is continuing a canvas already referenced in this conversation (by room_id, or a URL like ?room=[room_id] or /gdrive?id=[room_id]), pass it here. Omit to create a new canvas. |
| mermaid | string | yes | Mermaid diagram definition. Prefer converting compatible user requests into Mermaid instead of using add_elements. |
| config | object | no | Optional Mermaid rendering config. flowchart.curve is handled automatically. |
| timeout | number | no | Room lifetime in seconds (default: 3600, max: 86400). Only used when creating new canvas |
