I gave an LLM agent write access to my cloud drive. Three bugs taught me how to constrain it.

I wanted a media library that knew the difference between what should exist and what does. Most automation I tried picked one side. Some tools search well and never track what you already have. Others move files and assume the move worked. I wanted the gap between those two things to be the thing the software acted on. So I built Mediary Scout. You name a movie or a show. An LLM agent searches your indexers, transfers the best match into your own cloud drive, then reads the drive back to confirm
