The dbt Model Lineage Analyzer skill processes dbt Core manifest.json and catalog.json artifacts to construct comprehensive data lineage graphs across your analytics warehouse. It traces column-level lineage from source tables through staging, intermediate, and mart models, identifying transformation logic at each hop. The skill integrates with the dbt Cloud Administrative API v2 to pull run results, test outcomes, and freshness check data for operational lineage enrichment. Features include impact analysis for proposed model changes, orphan model detection, circular dependency identification, and exposure coverage reporting. Supports visualization export in DOT format for Graphviz rendering and Mermaid diagram syntax for documentation embedding. Provides automated data quality scoring based on test coverage, documentation completeness, and freshness SLA compliance.
