-   "description": "Edit a specific page in the current diagram by ID-based operations (update/add/delete cells).\n\nAll-or-nothing: if any operation fails, nothing is applied and every failure is listed.\n\nFreshness: the server remembers the last diagram state you have seen, and rejects this call only if the user edited the diagram in the browser since then. You do NOT need to call get_diagram before every edit: a rejected call changes nothing and includes the current XML of the page, so you can rebuild your operations and retry.\n\nCall get_diagram first only when you don't know the current diagram content (cell IDs, structure) — e.g. the diagram wasn't created in this conversation, or you're unsure your memory of it is accurate.\n\nMulti-page targeting:\n- page_id / page_name / page_index are optional; when all omitted, the FIRST page is targeted\n- Use list_pages to discover what pages exist\n\nOperations:\n- add: Add a new cell. Provide cell_id (new unique id within the page) and new_xml. One cell per operation.\n- update: Replace an existing cell by its id. Provide cell_id and complete new_xml.\n- delete: Remove a cell by its id. Only cell_id is needed. Its children and connected edges are deleted too, so give only a container's id.\n\nFor add/update, new_xml is the complete mxCell in the compact form (a shape with x, y, w, h; an edge with source and target). No XML comments. Every \" inside new_xml must be escaped as \\\" in the JSON.\n\nExample - Add a rectangle on the default (first) page:\n{\"operations\": [{\"operation\": \"add\", \"cell_id\": \"rect-1\", \"new_xml\": \"<mxCell id=\\\"rect-1\\\" value=\\\"Hello\\\" style=\\\"rounded=1;\\\" x=\\\"100\\\" y=\\\"100\\\" w=\\\"120\\\" h=\\\"60\\\"/>\"}]}\n\nExample - Delete a cell on the default page:\n{\"operations\": [{\"operation\": \"delete\", \"cell_id\": \"rect-1\"}]}",
