I have a bit more practical approach here (write up at some point): the most important thing is to rethink how you are instructing the agents and do not only rely on your existing codebase because: 1) you may have some legacy practices, 2) it is a reflection of many hands, 3) it becomes very random based on what files the agent picks up.

Instead, you should approach it as if instructing the agent to write "perfect" code (whatever that means in the context of your patterns and practices, language, etc.).

How should exceptions be handled? How should parameters be named? How should telemetry and logging be added? How should new modules to be added? What are the exact steps?

Do not let the agent randomly pick from your existing codebase unless it is already highly consistent; tell it exactly what "perfect" looks like.
