I can see how the situation is annoying there; I've had a similar frustration when doing manual code review for someone's obviously AI-slop PR only to have their bot auto-respond to my comments. There's an asymmetry of effort that feels unfair. Like, don't ask for manual review of something that contains lots of things that your own manual review should have caught first, and if I provide human feedback, I expect human responses.

That said, I wouldn't necessarily take it at face value that the person you were working with trusted the bot more than you— at the end of the day, the bot was doing all the implementation anyway, so all the interactions between her and the bot were probably framed in language like "what if we" or "I think it would be better if", so her saying "my programmer colleague thinks X" would naturally generate that "yeah your colleague is right, let's go that direction, makes sense" that she passed back to you, probably thinking it was a complement.

Maybe the real frustration is her not understanding the value-add that still exists there when someone with real expertise and more context can step in and provide that nudge in the right direction.
