Both human and AI should be able to understand the "way we do things around here" by reading the existing code. I could spend an hour telling someone how to write idiomatic code, and they will forget all of it until they actually do some work and see the codebase.

When Claude reads a significant portion of my codebase into context it should be suggesting idiomatic changes. Even if it doesn't initially read a bunch of the codebase to figure out a solution, it should definitely then be trained to do so explicitly to understand the coding standards. Just like a decent dev would do on their own.

The coding standard is quality code and one should bring it with themselves comming into the company. And if you mean linter & formatting rules then if company is not young then their elders had a fist fight to settle once and for all one standard, zip it into a file and everybody just use it

because it's not a person? because you have to do it all the time? because of the way literally all other software works?
