Sometimes it produces useful output. A good base of tests to start with. Or some little tool I'd never take the time to make if I had to do it myself.

On the other hand I tried to get help debugging a test failure and Claude spit out paragraph after paragraph arguing with itself going back and forth. Not only did it not help none of the intermediate explanations were useful either. It ended up being a waste of time. If I didn't know that I could have easily been sent on multiple wild goose chases.
