How to use this skill

Bring this guide into your coding agent with a prompt tailored to the tool you use.

  1. Open your project in Codex.
  2. Copy and paste the prompt below.
  3. Review files and risks before approving any action.
Prompt to paste
Inspect the Agent Skill at https://github.com/minicoohei/ai-agent-camp/blob/HEAD/.claude/skills/jupyter-to-marimo/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/jupyter-to-marimo, but wait for my approval before writing files or running scripts.

Copying this prompt does not install or run the skill. Review third-party files before use.

Converting Jupyter Notebooks to Marimo

IMPORTANT: When asked to translate a notebook, ALWAYS run uvx marimo convert <notebook.ipynb> -o <notebook.py> 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 to work with.

Steps

  1. Convert using the CLI

Run the marimo convert command via uvx so no install is needed:

uvx marimo convert <notebook.ipynb> -o <notebook.py>

This generates a marimo-compatible .py file from the Jupyter notebook.

  1. Run marimo check on the output
uvx marimo check <notebook.py>

Fix any issues that are reported before continuing.

  1. Review and clean up the converted notebook

Read the generated .py file and apply the following improvements:

  • Ensure the script metadata block lists all required packages. The converter may miss some.
  • Drop leftover Jupyter artifacts like display() calls, or %magic commands that don't apply in marimo.
  • Make sure the final expression of each cell is the value to render. Indented or conditional expressions won't display.
  • If the original notebook requires environment variables via an input, consider adding the EnvConfig widget from wigglystuff. Details can be found here.
  • If the original notebook uses ipywidgets, replace them with corresponding ui from marimo. A slider, for example, would be replaced with mo.ui.slider().
  1. Run marimo check again after your edits to confirm nothing was broken.
