Goal

• Renumber cells in a Jupyter notebook consecutively and ensure all function names are synchronized with cell headers

Workflow

Identify Current Numbering

• Read all existing cell headers and identify the current numbering
• Make sure to follow the sections from .claude/skills/notebook.rules.md:
  • # Notebook Structure and Headers (Markdown Header Structure and Naming, Sequential Cell Numbering)
  • # Code Architecture and Responsibility (Sync Function Names with Cell Numbers, Organize Code by Cell Order)
• Identify gaps, duplicates, or out-of-order cell numbers

Renumber Headers and Functions

• Renumber headers consecutively (1, 2, 3, ... and 1.1, 1.2, ... for sub-cells)
• Rename all functions in code cells and the *_utils.py file to match the new headers

Sync with Jupytext

• Sync the paired .py file with Jupytext following the conventions in # Code Architecture and Responsibility -> ## Utilities vs. Notebook Responsibilities in .claude/skills/notebook.rules.md

Conventions

• Follow the notebook conventions in .claude/skills/notebook.rules.md

Verification

• Confirm cell numbers are sequential with no gaps within each Part
• Confirm every cellN_*() function name matches its cell header number
• Confirm the .ipynb and paired .py file are in sync via Jupytext
