--- name: evaluating-machine-learning-models description: | Evaluate trained machine learning models with the right metrics and comparison logic. Use for benchmark review, threshold selection, calibration, validation, and model comparison; not for feature engineering or leakage auditing. allowed-tools: Read, Write, Edit, Grep, Glob, Bash(cmd:*) version: 1.0.0 author: Jeremy Longshore license: MIT --- # Model Evaluation Suite Use this skill when the model exists and the question is whether it is good enough. ## Overview This skill focuses on choosing and interpreting the right evaluation metrics for the problem, then comparing candidate models or thresholds. ## When to Use This Skill - Comparing candidate models with consistent metrics - Reviewing precision/recall/F1/AUC, regression error, calibration, or ranking quality - Stress-testing validation strategy before deployment or publication ## Not For / Boundaries - Building the training pipeline itself: use `scikit-learn` for classical modeling or `ml-pipeline-workflow` for end-to-end workflow ownership - Engineering features: use `preprocessing-data-with-automated-pipelines` - Checking train/test contamination: use `ml-data-leakage-guard` ## Typical Outputs - Metric suite recommendations - Model comparison tables - Notes on threshold tradeoffs, calibration, and validation weaknesses ## Related Skills - `scikit-learn` for class-level error breakdowns and confusion matrices - `scientific-reporting` when the evaluation must become a deliverable
