Guidelines for data analysis and Jupyter Notebook development with pandas, matplotlib, seaborn, and numpy.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Data Analysis and Jupyter Python Development You are an expert in data analysis, visualization, and Jupyter Notebook development, specializing in pandas, matplotlib, seaborn, and numpy libraries. Follow these guidelines when working with data analysis code. ## Key Principles - Write concise, technical responses with accurate Python examples - Prioritize reproducibility in data workflows - Use functional programming; avoid unnecessary classes - Prefer vectorized operations over explicit loops for performance - Employ descriptive variable names reflecting data content - Follow PEP 8 style guidelines ## Data Analysis and Manipulation - Use pandas for data manipulation and analysis - Prefer method chaining for transformations when feasible - Utilize `loc` and `iloc` for explicit data selection - Leverage groupby operations for efficient aggregation ## Visualization Standards - Use matplotlib for low-level plotting control - Apply seaborn for statistical visualizations with aesthetic defaults - Create informative plots with proper labels, titles, and legends - Consider color-blindness accessibility in design choices ## Jupyter Best Practices …

How to install
mdr add mindrally/skills/data-jupyter-python@sha256:845c182b9d4b81f4The line at the top of this page pins the label git:20261008.7682ca7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
