That's really interesting, first I have heard about automated tools to validate code.

Are there public tools out there you can use prior to commits for this purpose or are they generally done in-house?

The big one for Git is Overcommit[1]. The tools that it runs depend on the language, though. Some are community-driven[2], while others are baked into the language.[3]
