Notebook Structure

Jupyter notebooks are JSON documents with this high-level shape:

• nbformat and nbformat_minor
• metadata
• cells (a list of markdown and code cells)

When editing .ipynb files programmatically:

• Preserve nbformat and nbformat_minor from the template.
• Keep cells as an ordered list; do not reorder unless intentional.
• For code cells, set execution_count to null when unknown.
• For code cells, set outputs to an empty list when scaffolding.
• For markdown cells, keep cell_type="markdown" and metadata={}.

Prefer scaffolding from the bundled templates or new_notebook.py (for example, $CODEX_HOME/skills/jupyter-notebook/scripts/new_notebook.py) instead of hand-authoring raw notebook JSON.
