What it does

Jupyter To Marimo is an agent skill from ericmjl/llamabot. Convert a Jupyter notebook (.ipynb) to a marimo notebook (.py).

Its SKILL.md is about 480 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/latex.md` and `references/widgets.md`).

It sits in Data & Analytics, covering Jupyter notebooks. It works with Jupyter and marimo. The repository describes itself as: Pythonic class-based interface to LLMs.

When your agent uses it

  • Tasks that involve Jupyter notebooks

Example prompts

  • “/jupyter-to-marimo”

What it can do on your machine

Read from SKILL.md and the folder at commit 30d24ae. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • uvx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • koaning.github.io

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Jupyter To Marimo loads about 475 tokens when it runs, and up to ~2.9k if it reads all its reference files. Until then it costs about 20 tokens; SKILL.md has 236 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~20
When it runs · the whole SKILL.md, loaded when a task matches
~475
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 236 words (~475 tokens).

“IMPORTANT: When asked to translate a notebook, ALWAYS run uvx marimo convert -o FIRST before reading any files. This saves precious tokens - reading large notebooks can consume 30k+ tokens, while the converted .py file is much smaller and easier…”
