You can build Python-based interactive widgets for Jupyter and marimo notebooks with create-pywidget, and use learn-codebase as a Socratic tutor that teaches codebase understanding through questioning, challenges, and active recall when onboarding to new code.

They target Python developers and data practitioners working in reactive notebook environments like marimo and Jupyter, plus engineers onboarding to unfamiliar codebases who want structured, question-driven learning rather than passive documentation reading.

Invoke it with the /learn-codebase command when onboarding to a new codebase or deepening understanding of existing code. It maintains a learning journal that tracks your mastery over time and schedules reviews for retention.

The create-pywidget skill targets Python-based interactive widgets specifically for Jupyter and marimo notebook environments, aligning with the author's work on the marimo reactive notebook team.
