What

The NotebookEdit tool now comes with guidance on when to use it. Whenever Claude is about to change, add or delete a cell in a Jupyter notebook (a .ipynb file), it should use NotebookEdit rather than editing the file as text, which the edit tool refuses. The tool's main description is unchanged.

Why

This steers Claude toward the notebook tool, so it does not try a text edit that will be refused.
