 "summary": "Convert existing Jupyter notebooks to Marimo so they rerun dependent cells automatically and diff cleanly in git.",
 "who": "A data scientist tired of out-of-order cells and unreadable notebook diffs.",
 "problem": "Jupyter notebooks hide state, break when cells run out of order and store as noisy JSON.",
 "outcome": "Notebooks saved as pure Python that stay consistent and review well in pull requests.",
 "steps": [
  "Install with `pip install marimo` and try the tutorial with `marimo tutorial intro`",
  "Convert a notebook with `marimo convert your_notebook.ipynb > your_notebook.py`",
  "Open it with Marimo edit and fix any cells that redefine the same variable",
  "Commit the .py file and review changes like normal code",
  "Run it top to bottom as a script with `python your_notebook.py`"
 ],
 "agent_prompt": "Using marimo-team/marimo, convert <notebook.ipynb> with marimo convert, fix any multiple-definition errors so it runs reactively, and confirm `python your_notebook.py` executes it end to end.",
