# 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.
