Having a framework as guardrails (Hah!) for agents is still very powerful, in my experience working with Rails + Claude it works together really well and there's not really a downside compared to doing it completely from scratch.

I'd rather point the agent at and authentication gem and tell it to use that, vs telling it "build authentication, make no mistakes".

Isn't that an argument for pointing an agent at symfony or laravel, not at drupal?

I understood the parent comment to mean framework vs. writing everything from scratch, not necessarily about Drupal, Laravel, Symfony. Drupal just came up as it's the thread title. I'd apply that statement to each framework.
