Jupyter Notebook Skill

Create clean, reproducible Jupyter notebooks for two primary modes:

• Experiments and exploratory analysis
• Tutorials and teaching-oriented walkthroughs

Prefer the bundled templates and the helper script for consistent structure and fewer JSON mistakes.

When to use

• Create a new .ipynb notebook from scratch.
• Inspect notebook cells, outputs, metadata, dependencies, or execution state.
• Add, remove, reorder, or edit code and Markdown cells.
• Execute notebooks, refresh saved outputs, or troubleshoot kernel failures.
• Create or improve notebook tables, charts, and other visualizations.
• Convert rough notes or scripts into a structured notebook.
• Refactor an existing notebook to be more reproducible and skimmable.
• Build experiments or tutorials that will be read or re-run by other people.

Decision tree

• If the request is exploratory, analytical, or hypothesis-driven, choose experiment.
• If the request is instructional, step-by-step, or audience-specific, choose tutorial.
• If editing an existing notebook, treat it as a refactor: preserve intent and improve structure.

Choose the notebook tooling

Before inspecting, editing, or executing a notebook, check whether suitable Jupyter MCP tools are available.

• Prefer a connected Jupyter MCP server for notebook operations.
• If Jupyter MCP is unavailable or an MCP operation fails, explicitly tell the user that you are switching to manual notebook editing.
• Follow references/manual-editing.md before editing raw notebook JSON.
• Do not use MCP and manual JSON editing simultaneously for the same change.

Workflow

1. Lock the intent. Identify the notebook kind: experiment or tutorial. Capture the objective, audience, and what "done" looks like.

2. Scaffold from the template. Use the helper script to avoid hand-authoring raw notebook JSON. Resolve scripts/new_notebook.py against the base directory supplied when this skill is loaded; do not assume the skill is installed under the project's .kilo directory.

python3 "<SKILL_BASE_DIR>/scripts/new_notebook.py" \
  --kind experiment \
  --title "Compare prompt variants" \
  --out "compare-prompt-variants.ipynb"

python3 "<SKILL_BASE_DIR>/scripts/new_notebook.py" \
  --kind tutorial \
  --title "Intro to embeddings" \
  --out "intro-to-embeddings.ipynb"

3. Fill the notebook with small, runnable steps. Keep each code cell focused on one step. Add short markdown cells that explain the purpose and expected result. Avoid large, noisy outputs when a short summary works.

4. Apply the right pattern. For experiments, follow references/experiment-patterns.md. For tutorials, follow references/tutorial-patterns.md.

5. Edit safely when working with existing notebooks. Preserve the notebook structure; avoid reordering cells unless it improves the top-to-bottom story. Prefer targeted edits over full rewrites. If you must edit raw JSON, follow references/manual-editing.md.

6. Validate the result. Run the notebook top-to-bottom when the environment allows. If execution is not possible, say so explicitly and call out how to validate locally. Use the final pass checklist in references/quality-checklist.md.

Templates and helper script

• Templates live in assets/experiment-template.ipynb and assets/tutorial-template.ipynb.
• The helper script loads a template, updates the title cell, and writes a notebook.

Temp and output conventions

• Use the system temporary directory for intermediate files and delete them when done.
• Save the final notebook in the user-requested location, or in the current project directory when no location is specified.
• Use stable, descriptive filenames (for example, ablation-temperature.ipynb).

Dependencies (install only when needed)

Optional Python packages for local notebook execution:

python3 -m pip install jupyterlab ipykernel

The bundled scaffold script uses only the Python standard library and does not require extra dependencies.

Environment

No required environment variables.

• references/tutorial-patterns.md: tutorial structure and teaching flow.
• references/notebook-structure.md: notebook JSON shape.
• references/manual-editing.md: manual editing and execution fallback when Jupyter MCP is unavailable.
• references/quality-checklist.md: final validation checklist.
