My "minimalist" list of git commands:

    git add
    git blame
    git branch
    git checkout
    git cherry-pick
    git clone
    git commit
    git diff
    git fetch
    git log
    git merge
    git pull
    git push
    git reset
    git rm
    git stash
    git status

17 commands in total. I don't think it is possible to be a professional software engineer without being familiar with them. Granted, some of these you may need more frequently than others.

My guess is, the OC relies on their IDE/editor for the functionality provided by some of these commands. But then, why not just go all the way. Just use all VC features provided by your IDE, and claim that you need zero git commands.
