Obviously the agent would need to build a very extensive test setup for Paint.NET, a lot of it with computer use or something similar.

Opening the same files, performing the same clicks, etc should output the same on paint.net and the clone.

Obviously, yes. That's why it needs to be included in any estimate.

My point being "a few weeks and 8M tokens" is wildly unrealistic.

		Yeah for sure. Easily 10x that. And obviously we're talking just output tokens. I was mostly just pointing out a theoretical lower bound.
