Skills in this repo

1Data Science ExpertData-science-expert is a procedural expert skill that steers coding agents through serious analytics work: exploratory analysis, preprocessing, feature engineering, statistical inference, time series, A/B tests, and both classical ML and visualization best practices. It is aimed at solo builders shipping data-backed SaaS, internal dashboards, or research prototypes who want consistent pandas and numpy patterns instead of one-off chat snippets. The skill documents core concepts across supervised and unsupervised learning, model selection, hyperparameter tuning, and ensemble methods, plus Matplotlib, Seaborn, and Plotly for statistical and interactive plots. A DataCleaner class example shows how to log missing-value strategies before modeling. Invoke it when you are implementing analysis notebooks, training scripts, or evaluation pipelines inside your repo. It is guidance and code structure, not a hosted notebook service, and expects Python execution via the skill’s Bash allowance.1installs
