This skill provides standardized production patterns for establishing data integrity throughout the modern data stack. It enables developers to implement sophisticated validation suites using Great Expectations, build comprehensive dbt test layers, and define machine-readable data contracts between teams. By focusing on the six dimensions of data quality—completeness, uniqueness, validity, accuracy, consistency, and timeliness—this skill ensures reliable data pipelines and prevents downstream failures through automated CI/CD integration and real-time monitoring patterns.
