Here's the thing nobody warns you about when you start delegating real work to AI.
The model doesn't tell you when it messes up.
It just hands the document back. Looking clean. Structure will be good. Maybe even better than what you gave it. And you move on with your day not knowing that three rows are gone. Or a column got renamed. Or a function got rewritten in a way the rest of your codebase doesn't know about.
I vibe code. I delegate to Claude constantly. So when Microsoft Research dropped a paper this week called "LLMs Corrupt Your Documents When You Delegate", I read it like it was about me.
And honestly? It was.
I think it might be the most important AI paper of the month. Not because of what it predicts. Because of what it actually measured.
The Test That Actually Made Sense
Here's what the researchers did. And I love how clean this is.
Take any document. A code file, a 3D model. Pick something. Now ask an AI to edit it. "Convert measurements to mm." Then ask the AI to reverse the edit. "Convert them back to cups." or something like that..
If the AI is any good, you should get back the original. Right? Simple round trip.
