annotating-task-lineage
Annotate Airflow tasks with data lineage using inlets and outlets. Use when the user wants to add lineage metadata to tasks, specify input/output datasets, or enable lineage tracking for operators without built-in OpenLineage extraction.

Annotating Task Lineage with Inlets & Outlets This skill guides you through adding manual lineage annotations to Airflow tasks using inlets and outlets. Reference: See the OpenLineage provider developer guide for the latest supported operators and patterns. On Astro Lineage annotations defined with inlets and outlets are visualized in Astro's enhanced Lineage tab, which provides cross-DAG and cross-deployment lineage views. This means your annotations are immediately visible in the Astro UI, giving you a unified view of data flow across your entire Astro organization.
