Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Converting Jupyter Notebooks to Marimo
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 to work with.
Steps
- Convert using the CLI
Run the marimo convert command via uvx so no install is needed:
uvx marimo convert -o This generates a marimo-compatible .py file from the Jupyter notebook.
- Run
marimo checkon the output
uvx marimo check Fix any issues that are reported before continuing.
- 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%magiccommands 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
EnvConfigwidget from wigglystuff. Details can be found here. - If the original notebook uses ipywidgets, see
references/widgets.mdfor a full mapping of ipywidgets to marimo equivalents, including patterns for callbacks, linking, and anywidget integration. - If the notebook contains LaTeX, see
references/latex.mdfor how to port MathJax syntax to KaTeX (which marimo uses).
- Run
marimo checkagain after your edits to confirm nothing was broken.
