Historically, I did it the other way around: have some autogenerated shell commands (dev, test, pull...etc) on my local machine that detect which language the project in the current folder is using, and calls commands accordingly. I did it this way because, in my case, it was challenging to consolidate multiple projects across multiple organizations under a single tool.

It's public, but I realize I haven't pushed my local updates for a while now. https://github.com/Betree/dev-commander
