Exploratory data analysis patterns -- profiling, distributions, correlations, segmentation, anomaly detection, and translating statistics into narrative insights.
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.

## Overview
Turn raw data into actionable insight statements. This skill covers the full EDA pipeline: profiling the dataset, exploring distributions, finding correlations, detecting anomalies, and -- critically -- translating statistical findings into business-language narratives tagged with story intents for downstream visualization.
The cardinal rule: **statistics are not insights**. "Mean revenue is $4.2M" is a statistic. "Revenue grew 34% YoY but growth is decelerating -- Q3 peak was 8% vs. 22% last year" is an insight.
## Module 1: Data Profiling
First pass on any dataset. Compute before exploring.

The line at the top of this page pins the label git:20260728.80a7ab6, 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.
