With that, we're back to square one again. Why not just provide that set of guidelines, prompts, and skills locally, which is very likely something modern LLMs can already handle?

Can't really see the point of settings up a separate AI code review step and make that into some sort of stage that everybody pretends to care. Just to make it look like something extra is, hopefully, happening?

Plus, I feel like any previous context a developer had before submitting the PR must have the most accurate context rather than a code review AI.

It's more on pure curiosity than ranting.
