It was on 2 separate private repos, personal projects. No one else working on those

But now that you asked, I recently had a similar experience with Codex, but on a shared repo. I also was using a slightly older model, and the all of a sudden it kinda stopped running tasks. I would ask it to do something and the it would just kind of do an analysis, then give me a recommendation of what to do. I had to tell it to execute the task, and then it would “be lazy”, like run one part then give me a recap and recommendation again instead of just going

Switched to a newer model, and the issue was instantly gone
