Profile datasets for schema, distributions, nulls, cardinality, outliers, relationships, and data quality.
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
## Structural Reconnaissance ### Table-Level Inventory Start every new dataset encounter by answering these questions: - What is the total row and column count? - What does each row represent (the grain)? - Which column or columns uniquely identify a row? - When was the most recent data loaded? - What is the earliest date in the dataset? ### Classifying Columns by Role Assign every column to one of these categories: - **Key**: Primary keys, foreign keys, entity identifiers - **Attribute**: Categorical fields used for grouping or filtering (region, status, plan_type) - **Measure**: Numeric fields intended for aggregation (revenue, duration, score) - **Timestamp**: Date or datetime fields (created_at, processed_on, event_date) - **Free-text**: Unstructured strings (descriptions, comments, names) - **Flag**: Binary true/false indicators - **Nested**: JSON blobs, arrays, or embedded structures ## Column-Level Inspection ### Universal Checks (All Column Types) - Null count and null percentage - Count of distinct values and cardinality ratio (distinct / total rows) - Top 5-10 most frequent values with their occurrence counts …

How to install
mdr add vm0-ai/vm0-skills/data-profiling@sha256:2474afd695d982bfThe line at the top of this page pins the label git:20260709.c4cfc48, 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.
