Now, since we’ve looked at the basic starter project and we have an idea of what agentic AI is and how it could possibly help us, let’s see if we can ask Codex to give us some help implementing our desired features. One of the things that we wanted to do was to make some different models — baked goods and beverages — and also maybe get a different view for the beverages.

  Add the ability to provide specific recipes such as baked goods and beverages, adding any other necessary properties. Suggest a new detail view for beverages that is unique from the existing detail view.
  Update the SwiftData model to use model inheritance. Use the original recipe model and add baked good and beverage models that inherit from recipe.
