Notebook Workflow

Skill: Notebook Workflow

Use this skill when creating, editing, executing, or reviewing Jupyter notebooks.

Purpose of Notebooks

• Notebooks are for exploration and communication.
• Reusable logic should be extracted to src/analysis_project/.

Rules

• Keep notebooks restartable from a clean kernel (Kernel → Restart & Run All must work).
• Avoid hidden state — do not rely on cells being run in a non-linear order.
• Do not include secrets or customer-level records in notebook outputs.
• Prefer saving final charts and tables to outputs/.

Naming Convention

NNN_short_description.ipynb

Example: 001_data_exploration.ipynb, 002_feature_analysis.ipynb

Automation

• Use papermill for parameterized notebook execution when automation is needed.

uv run papermill notebooks/input.ipynb notebooks/output.ipynb -p param_name value

Structure

1. Header cell (Markdown): Title, author, date, objective.

   # タイトル
   - **作成者**: 名前
   - **作成日**: YYYY-MM-DD
   - **目的**: この分析で明らかにしたいこと
   

2. Imports: All imports in the first code cell.

3. Configuration: Parameters, paths, constants.

4. Analysis: Exploratory or analytical cells.

5. Summary: Key findings and next steps.

Cleanup Before Commit

• Clear large outputs that are not essential for review.
• Ensure no credentials or PII in cell outputs.
• Verify the notebook runs end-to-end with a fresh kernel.
