When your dashboard looks off or someone asks if they can trust yesterday's numbers, this checks table timestamps against a freshness scale (fresh under 4 hours, stale up to 24, very stale beyond that). It finds timestamp columns across common ETL patterns, queries for last update times, and reports status in a scannable format. If data is stale, it points you to the relevant Airflow DAG and suggests using the debugging-dags skill to investigate failures. Honestly just saves you from writing the same timestamp queries over and over, and the staleness scale gives you a shared vocabulary when something hasn't updated.
