I don't disagree that having a deterministic CLI is useful, but I'd argue that's not the question here, because the CLI is what the statistical machine will be using. The question is whether the time spend doing it manually is worthwhile compared to the tokens spend on it. I'd argue that if you instead learn how to pick the right model for the right job so that you don't use something way more expensive than needed for the task at hand, the token overhead will be extremely minimal for stuff like git operations; knowing that you can use something cheaper than like, Astra or Opus if all you want to do is a quick git cleanup and push is going to save your employer a lot more money in the long run than if you insist on doing every messy rebase by hand.
In terms of team practices, that basically seems like a code review thing. If my team has conventions around git, and a PR doesn't fit them, that's something I would point out regardless of how the PR was generated. If a team member is repeatedly not meeting the expectations we've all agreed upon, I would deal with it in the same way I always have; reach out and offer guidance for how to do things the way they're supposed to, notify my manager if they continue having trouble with it, and eventually just not bother looking at their PRs if they absolutely refuse to do things the way everyone else on the team has agreed they should be done.
One time setup commands are the sort of thing people do once when setting up the repo, but dont use day to day. its understandable that people dont have that memorized and will reach for a man page, google or an AI.
Some 6-figure per year developer spending a quarter’s worth of tokens to do something they do once a month or so is not something I’ll ever care to optimize away…
