Agreed- this is the same problem we have with trusted admins or devs who have elevated privileges on their networks. We have to trust that the admins won't use their power to steal company secrets or misuse company resources. If you don't trust the admins, then they can't fix things on your network and there is no point in having them.

If you want an agent to act on its own, like pushing to a git repo, managing dependencies, building and testing, etc., then you have to trust it as much as any other privileged user.

If you don't want to trust it, then you're just forcing yourself into the reverse centaur role, where the agent edits some code, but then has to stop and ask you to push the changes or build the software again and run the unit tests.

I suppose there is a principled way of doing things like "I trust you do do basic commits but I will handle merge conflicts" and "you can build modules in this directory but you can't build outside of it" but this is just a lot of effort that most orgs won't bother with.
