Agreed, but I'm working on something >100k lines of code total (a new language and a runtime).

It helps when you can implement new things as if they're green-field-ish AND THEN implement and plumb them later.

In a well-designed system, you can point an agent at a module of that system and it's perfectly capable of dealing with it. Humans also have a limited context window, and divide and conquer is always how we've dealt with it. The same approach works for agents.

Yes, but the problem is that LLMs don't default to well-designed systems... So, you need to aggressively stay on top of them.
