Replaces, inserts, or deletes a single cell in a Jupyter notebook (.ipynb file). Usage: - You must use the ${READ_TOOL_NAME} tool on the notebook in this conversation before editing — this tool will fail otherwise. - `notebook_path` must be an absolute path. - `cell_id` is the `id` attribute shown in the ${READ_TOOL_NAME} tool's `` output. It is required for `replace` and `delete`. - `edit_mode` defaults to `replace`. Use `insert` to add a new cell after the cell with the given `cell_id` (or at the beginning of the notebook if `cell_id` is omitted) — `cell_type` is required when inserting. Use `delete` to remove the cell.
