Similarly for me. I have a recent example too. I run a bunch of eps32 devices at home, using esphome. Pre-AI I wrote all the yaml myself and understood what’s happening and didn’t have any very bespoke hacks.

Recently I asked an agent for a feature where the screen will get dimmer after some time, and eventually after a day the screen will turn off and then turn back on if I tap, which should be pretty easy in esphome.

But: some past agent decided what it wanted wasn’t in esphome, so it made its own custom module in c++ for the display, spelunking in pdf datasheets; then the weeds were so deep the new agent decided to add on to that, and to read the power controller and display controller spec sheets and somehow implement my dimming feature by writing raw values to some nondescript registers.

The contraption worked until it didn’t and once every so often my esp32 would just completely hang with black screen and no connnectivity and needed a power cycle, presumably because whatever low level register writing the agent implemented eventually breaks something. I told the agent to get rid of all custom stuff and wherever possible just use default esphome yaml, now it’s been working fine. I don’t really have a point with the anecdote, just that I’m also getting tired of such scenarios like the OP.
