shap SKILL.md skillA

shap from marielynneblock/arcanum-artifex is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add marielynneblock/arcanum-artifex/shap@git:20260710.0115f49

Pins git:20260710.0115f49 in mdr.lock. Pin the fingerprint instead.

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, analysing 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…

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

# SHAP (SHapley Additive exPlanations)

## Overview

SHAP is a unified approach to explain machine learning model outputs using Shapley values from cooperative game theory. This skill provides comprehensive guidance for:

- Computing SHAP values for any model type
- Creating visualisations to understand feature importance
- Debugging and validating model behaviour
- Analysing fairness and bias
- Implementing explainable AI in production

SHAP works with all model types: tree-based models (XGBoost, LightGBM, CatBoost, Random Forest), deep learning models (TensorFlow, PyTorch, Keras), linear models, and black-box models.

## When to Use This Skill

**Trigger this skill when users ask about**:
- "Explain which features are most important in my model"
- "Generate SHAP plots" (waterfall, beeswarm, bar, scatter, force, heatmap, etc.)
- "Why did my model make this prediction?"
- "Calculate SHAP values for my model"
- "Visualise feature importance using SHAP"
- "Debug my model's behaviour" or "validate my model"
- "Check my model for bias" or "analyse fairness"
- "Compare feature importance across models"
- "Implement explainable AI" or "add explanations to my model"

How to install

The exact contents, by fingerprint
mdr add marielynneblock/arcanum-artifex/shap@sha256:b006388e620dfc6f

The line at the top of this page pins the label git:20260710.0115f49, 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.
