Yeah. The times I have let claude off the read-only leash, it's gone fine for me too (with stern warnings not to do anything stupid, and a close eye). But that's not really solving the same problem as this project, I guess. From what I can see this is using a safer and more reproducible method (and not k8s native, so it feels a little foreign to me).
In Zed I just have it auto approve everything, macOS will scream if "Zed" tries to escape the folder its in anyway.
Opus 4.5 is pretty good about following instructions to not do anything destructive, but Gemini 3 Flash actively disregards my advice and just starts running commands. Definitely recommend setting up default-readonly access for stuff like this and requiring some kind of out-of-band escalation process for when you need to do writes/destroys.
