jupyter-notebooks

A workflow for creating or checking repeatable SQL or Python notebooks—documents that combine runnable code, analysis, and results.

In plain words
What is it for?
Use it to build analysis reports, experiment logs, diagnostic notebooks, data-quality checks, market-sizing calculations, or runnable companions for reports.
Why use it?
It helps make exploratory work reviewable, rerunnable, and easier to hand off instead of leaving it as an untracked scratchpad.

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-notebooks 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Use $validate-data when notebook results support a recommendation, shared claim, or decision.

Jupyter Notebooks

Create clean, reproducible Jupyter notebooks that are easy to skim, rerun, and handoff. Treat the notebook as a reader-facing analysis artifact, not a scratchpad dump. Notebook work is not complete until the notebook executes successfully top-to-bottom, or the execution gap is called out with the exact validation steps needed to reproduce it.

Workflow

  1. Lock the notebook mode and scope.

    Decide whether the notebook is an analysis report, experiment log, diagnostic notebook, data-quality check, market-sizing calculation, model exploration, tutorial, or companion artifact for a report. Identify the reader, decision, expected handoff, required inputs, and whether the task calls for a new notebook or targeted edits to an existing one.

  2. Inspect or scaffold with notebook-safe tooling.

    Prefer JupyterLab, nbformat, nbclient, or an existing scaffold utility over hand-editing raw JSON. When editing an existing notebook, preserve its intent and minimize JSON churn. Avoid reordering cells unless it clearly improves the top-to-bottom story. If raw JSON editing is unavoidable, validate the notebook structure before finishing.

  3. Structure the notebook for the chosen mode.

    For analytical notebooks, default to:

    1. ## tl;dr
    2. ## Context & Methods
    3. ## Data
    4. ## Results
    5. ## Takeaways

    Write tl;dr and takeaways after reviewing executed outputs. Use concrete observed values, visible patterns, rows, or charts, not assumptions. Include a ### Key Assumptions subsection in Context & Methods when assumptions affect correctness.

    For tutorials or walkthroughs, adapt the same discipline to a teaching flow:

    1. ## Goal
    2. ## Setup
    3. ## Steps
    4. ## Checks
    5. ## Next Steps
  4. Build a clear data and computation path.

    Separate setup, imports, parameters, data loading, data preparation, calculations, visualizations, and interpretation. If the notebook uses both SQL and Python, keep complex SQL in SQL cells or separate query files rather than large embedded Python strings unless there is a clear reason. Use descriptive variable names and keep each code cell focused on one step.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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-notebooks is a skill published in the GitHub repository XiaomiMiMo/MiMo-Code (12,923 stars, last pushed yesterday), licensed MIT. It adds 49 tokens to every session and 1,541 once invoked, about $0.0002 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 2026-08-30.
