I implemented version of this several years ago, except against human players instead of against an AI, and with randomly-generated levels instead of a succession of harder and harder levels.

It was a semester project where we had to hand in a game satisfying a few basic requirements, and since we were done early we were allowed to add as many extra features as we wanted. One of those features is that whenever you clicked on a unit and ordered it to do something, a log message would show you a ruby command which would do the same. You could then open the console and control your units using arbitrary ruby code, and you could also attach AI scripts to your units.

This was before the era of github, so the source may or may not have been lost to history. I'll update this comment if I manage to find it.
