+- Build Data Vault 2.0 models (hubs, links, satellites, business vault)
 - Add or modify SQL logic in an existing model
 - Generate sources.yml or schema.yml from warehouse metadata

 - Check existing models for naming conventions and patterns
 - **Check dependencies:** If `packages.yml` exists, check for `dbt_packages/` or `package-lock.yml`. Only run `dbt deps` if packages are declared but not yet installed.
