data-observability
by dtsong
"Use this skill when implementing monitoring, alerting, and incident response for data pipelines. Covers freshness monitoring, volume anomaly detection, schema change detection, alerting patterns, and incident response workflows. Common phrases: \"data freshness\", \"pipeline monitoring\", \"data anomaly\", \"schema drift\", \"data alerting\", \"incident response\", \"data observability\", \"stale data\". Do NOT use for writing dbt models (use dbt-transforms), pipeline scheduling (use data-pipelines), or data quality testing as deliverables (use data-testing)."
