Claude Cowork Plugin
📊Data Scientist
Design experiments, profile datasets, build models, and audit them for bias before shipping
The Data Scientist plugin helps you move from a dataset to a defensible production model. Every command works standalone with your input — describe the experiment, dataset, or model and get a structured draft ready for your review.
Use /design-experiment to plan an A/B test or experiment with sample size, power analysis, and recommended duration. Use /analyze-dataset to ingest a CSV or Parquet description, generate a data-quality report, flag outliers and biases, and suggest transforms. Use /build-model to recommend a model architecture, generate a scikit-learn or XGBoost template, and document assumptions. Use /eval-model to compute cross-validation, generate a confusion matrix, and audit feature importance for bias.
The plugin's skills activate automatically when relevant: Dataset Profiling auto-scans for missing values, outliers, class imbalance, correlation issues, and schema drift, plus Model Card Generation auto-generates Model Cards covering intended use, limitations, and training data provenance per the HuggingFace and Mitchell et al. standard.
Commands
Click a command to copy it. To run it in the Claude app, type it and pick it from the menu that appears; pasting it sends plain text instead of running it.
/design-experimentPlan an A/B test or experiment with sample size, power analysis, and recommended duration
/analyze-datasetGenerate a data quality report from a dataset description, flag outliers and biases, suggest transforms
/build-modelRecommend model architecture, generate scikit-learn or XGBoost template, document assumptions
/eval-modelCompute cross-validation, generate confusion matrix, audit feature importance for bias
Skills
Skills activate automatically when Claude Cowork detects you're working on relevant tasks — no slash command needed.
Dataset Profiling
Auto-scans for missing values, outliers, class imbalance, correlation issues, and schema drift
Model Card Generation
Auto-generates Model Cards (intended use, limitations, training data provenance) per HuggingFace and Mitchell et al. standard
Usage examples
