Jupyter Notebook Edit: Inconsistent Cell Insertion Order Breaks Code Generation

Resolved 💬 8 comments Opened Aug 5, 2025 by fonnesbeck Closed Jan 11, 2026

Bug Description
Claude code seems incapable of working with Jupyter notebooks. Cells are added in arbitrary/random order even when explicitly being told where to implement edits. This severely limits its use in data science applications.
