I like to constrain it as much as possible to ignore variables and function names; the human stuff.

With a new code base my first goal understand how it CRUDs state. What structures and what operations?

Less concerned at the outset if its sorting carrots or processing orders for shirts.

AI seems to work way better for me when I tell it to ignore the use case and focus on surfacing runtime and mathematical operations embedded in the code.

Constraints on new abstraction and telling it to stick to math terms and types and objects also seems to help avoid hallucinations and layers of useless indirection.
