Add the basic invocations for formatting, linting, testing, etc. can be boilerplate copied into a repo - maybe with a Makefile or similar that is somewhat language agnostic and can wrap anything.
Run these locally before commit, and have CI do it too. You'll get a baseline level of "not total garbage" in terms of automated checks, and even if there are no real tests, at least there's an obvious place to add them later.
