Turns a dbt Core project into an Airflow DAG/TaskGroup using Astronomer Cosmos. Use turning a dbt Core project into an Airflow DAG or TaskGroup with Astronomer Cosmos. Before implementing, verify dbt engine, warehouse, Airflow version, execution environment, DAG vs TaskGroup, and manifest availability.

git clone https://github.com/astronomer/agents /tmp/agents && ln -s /tmp/agents/skills/cosmos-dbt-core ~/.claude/skills/cosmos-dbt-core
```

## From README

Cosmos + dbt Core: Implementation Checklist Execute steps in order. Prefer the simplest configuration that meets the user's constraints. Version note: This skill targets Cosmos 1.11+ and Airflow 3.x. If the user is on Airflow 2.x, adjust imports accordingly (see Appendix A). Reference: Latest stable: https://pypi.org/project/astronomer-cosmos/ Before starting, confirm: (1) dbt engine = Core (not Fusion → use cosmos-dbt-fusion), (2) warehouse type, (3) Airflow version, (4) execution environment (Airflow env / venv / container), (5) DbtDag vs DbtTaskGroup vs individual operators, (6) manifest availability.
