SKILL.md

Create Python-based interactive notebooks with marimo's reactive cell architecture.

Notebooks are pure Python files with @app.cell decorated functions representing cells; dependencies and inputs/outputs are automatically managed through function parameters

Supports three execution modes: script mode (non-interactive testing), interactive browser editing, and CLI execution via uv run marimo

Use mo.app_meta().mode == "script" to detect execution context and adapt data sources without duplicating UI elements or wrapping logic in conditionals

Built-in linting via marimo check catches common mistakes; optional pytest integration enables test cells prefixed with test_

Notes for marimo Notebooks

marimo uses Python to create notebooks, unlike Jupyter which uses JSON. Here's an example notebook:

# /// script
# dependencies = [
#     "marimo",
#     "numpy==2.4.3",
# ]
# requires-python = ">=3.14"
# ///

import marimo

__generated_with = "0.20.4"
app = marimo.App(width="medium")
