notebook.format_md_cells is a skill for Claude Code from gpsaggese/helpers. It costs 9 tokens per session (274 once invoked), scanned A, original, Apache-2.0.

A formatting task for Markdown cells in an interactive Jupyter notebook. Jupyter notebooks combine runnable code with text, and this task presents the text as concise, nested bullet points without changing its meaning.

In plain words
What is it for?
Use it to reformat Markdown cells, align each explanation with its interactive code cell, and check that the notebook files stay in sync.

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

notebook.format_md_cells 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 yesterday.

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.

What it actually says

Goal

  • Given an interactive Jupyter notebook, format all the markdown cells without changing their content

Workflow

Sync Markdown Cells

  • Sync every markdown cell with its interactive cell

Markdown Cells Needs to Use Bullet Lists

  • Structure the text in markdown cells as markdown bullet points, with nested bullets for clarity and conciseness, following
    • .claude/skills/slides.rules.md: slide formatting
    • .claude/skills/text.rules.md: bullet point formatting
  • Follow ## Use Bullet-Point Comments for Structured Explanations in .claude/skills/notebook.rules.md

Sync Notebook

  • Finally, sync the paired .py file with Jupytext, per # Code Architecture and Responsibility -> ## Utilities vs. Notebook Responsibilities in .claude/skills/notebook.rules.md

Conventions

  • Always follow .claude/skills/notebook.rules.md

Constraints

  • Do not change the intent of the cell

Verification

  • Confirm the meaning of every markdown cell is unchanged
  • Confirm the .ipynb and paired .py file are in sync via Jupytext

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.
