If you're running dbt Fusion (not Core) with Astronomer Cosmos on Airflow, this walks you through the Fusion-specific setup that trips people up. It requires Cosmos 1.11 or later and only works with LOCAL execution mode pointing to the Fusion binary. The skill covers binary installation via Dockerfile, ExecutionConfig constraints, and warehouse compatibility (Snowflake, Databricks, BigQuery, Redshift only during preview). Notably clear about what won't work: no async mode, no virtualenv since Fusion is a binary. Includes both DbtDag and DbtTaskGroup patterns with actual code. The validation checklist at the end is practical, especially the note about testing a manual run before declaring victory.
