There was a code reviewer starting with M before Critique iirc (Mondrian I wanna say?). The M code reviewer was completely written in Python iirc.
No I mean that in code search you could click "edit" and just change something, which would then post a CL immediately, which you could set to auto-approve, for quick changes.
I believe it was part of cider (the first non-vscode version)
Yup, you guessed it.
I was the eng manager for that for a bit, added some APIs to use to do code reviews inside of Eclipse or IntelliJ. That idea never took on, but when when I showed it to the code search team in Munich, they loved it.
Critique was a fast follow.
