alt Hacker NewsGemini CLI is a wild beast. The stories of it just going bonkers and refactoring everything it reads on its own are not rare. My own experience was something like, "Edit no code. Only give me suggestions. blah blah blah" first thing it does is edit a file without any other output. It's completely unreliable.
Pro 3 is -very- smart but it's tool use/following directions isn't great.
I've been using Gemini 3 in the CLI for the past few days. Multiple times I've asked it to fix one specific lint error, and it goes off and fixes all of them. A lot of times it fixes them by just disabling lint rules. It makes reviewing much harder. It really has a mind of its own and sometimes starts grinding for 20 minutes doing all kinds of things - most of them pretty good, but again, challenging to review. I wish it would stick to the task.
