Agents that treat notebooks as plain text break outputs and metadata. Feeding structured per-cell context, including execution state and outputs, lets the model edit notebooks without corrupting them.
Key takeaways · AI-distilled
Cline sends notebook content to the model as structured per-cell JSON (cell type, source lines, metadata, execution count and outputs, including error traces) rather than flat text, so the model sees each cell's execution state and results.
For .ipynb files Cline edits the cell JSON directly instead of applying text diffs as it does for .py files, which Cline says keeps cell boundaries, execution counts, metadata and output associations intact.

Cline credits an engineering contribution from Amazon for the feature, which is turned on with the Enhanced Notebook Interaction setting.
