jupyter-notebook

jupyter-notebook is a skill for Claude Code from ulises-jeremias/agent-toolkit. It costs 61 tokens per session (1,234 once invoked), scanned A, original, MIT.

A tool for creating, structuring, and refactoring Jupyter notebooks, which are interactive documents that combine code, results, and explanations.

In plain words
What is it for?
It scaffolds experiment and tutorial notebooks, converts scripts or notes, and improves the structure and reproducibility of existing .ipynb files.
Why use it?
It provides consistent notebook layouts and reduces errors when turning experiments, tutorials, scripts, or rough notes into notebooks that others can read and rerun.

    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

jupyter-notebook scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Jupyter Notebook

Create clean, reproducible Jupyter notebooks for two primary modes:

  • Experiments — exploratory analysis, ablations, hypothesis testing.
  • Tutorials — instructional walkthroughs, teaching-oriented notebooks.

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.
  • 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

  • Exploratory / analytical / hypothesis-driven → experiment.
  • Instructional / step-by-step / audience-specific → tutorial.
  • Editing an existing notebook → treat as a refactor: preserve intent and improve structure.

Prerequisites

  • python3 (provided by bootstrap).
  • Optional: uv for local notebook execution and dependency isolation (also from bootstrap).

skills check jupyter-notebook validates python3 is present.

Helper script

The bundled scaffolder (scripts/new_notebook.py, stdlib only) loads a template, updates the title cell, and writes a notebook to --out. Two ways to invoke it:

Option A — newnotebook wrapper (recommended)

bootstrap installs a tiny wrapper at ~/.local/bin/newnotebook so the script is available without remembering its full path:

newnotebook --kind experiment \
  --title "Compare prompt variants" \
  --out output/jupyter-notebook/compare-prompt-variants.ipynb

newnotebook --kind tutorial \
  --title "Intro to embeddings" \
  --out output/jupyter-notebook/intro-to-embeddings.ipynb

Option B — call the script directly

python3 ~/.local/share/agent-toolkit/skills/jupyter-notebook/scripts/new_notebook.py \
  --kind experiment \
  --title "Compare prompt variants" \
  --out output/jupyter-notebook/compare-prompt-variants.ipynb

If you prefer uv for a pinned interpreter:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

jupyter-notebook is a skill published in the GitHub repository ulises-jeremias/agent-toolkit (16 stars, last pushed today), licensed MIT. It adds 61 tokens to every session and 1,234 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
