Confusion Matrix Generator
Purpose
Use this skill when the user already has classification outputs and needs to understand where the model is getting confused.
When to Use
Use this skill when:
- Breaking down false positives and false negatives by class
- Comparing thresholds or class weights for a classification model
- Explaining which classes are systematically confused with one another
Not For / Boundaries
- Regression evaluation: use
evaluating-machine-learning-models - Leakage audits: use
ml-data-leakage-guard - End-to-end training runs: use
training-machine-learning-models
Typical Outputs
- Confusion matrix tables or heatmaps
- Per-class precision/recall breakdowns
- Actionable notes on thresholding, relabeling, or class balancing

Model interpretability and explainability using SHAP (SHapley Additive exPlanations). Use this skill when explaining machine learning model predictions, computing feature importance, generating SHAP plots (waterfall, beeswarm, bar, scatter, force, heatmap), debugging models, analyzing model bias or fairness, comparing models, or implementing explainable AI. Works with tree-based models (XGBoost, LightGBM, Random Forest), deep learning (TensorFlow, PyTorch), linear models, and any black-box model.
