In most cases, these aren't "tech skills." They're expression skills; mostly programming languages.
I surmise that the top skill isn't even listed here, and it's git. If somebody doesn't have VCS chops, that's the first thing they need to learn to be a team player.
That's a good observation. However, only a few job posts mention git, even though it's probably used by most companies. I would assume the reason is that git is pretty easy to learn in 1 or 2 days (at least the basic functionality) and programmers shouldn't be rejected based on that.

Is this a "tech skill?" Or a "teamwork skill?"
