I help maintain two separate projects for looking for LLM-generated code in open-source repositories.
slopcheck is a CLI tool I created for checking repositories for signs of slop in git histories. It also shows the last commit with no signs.

slopscore does the same thing, but it also provides a Web interface and is more comprehensive at the moment.

Both projects are maintained by teams of awesome developers. Check them out!
