Hey HN!
We've been helping other companies build their AI code reviewers, and noticed that people ended up writing similar rules.
So we built a directory for them! We've also compiled instructions for all the major code reviewers out there (Github Copilot, Coderabbit, Greptile, Diamond).
The biggest thing we've done is port strong migrations (https://github.com/ankane/strong_migrations) to other languages and ORMs. If you've ever used ruby and miss strong migrations - well, you can have them now.
We plan on keeping this up to date over time with more helpful rules.
If you have any that you added to your code review process, please feel free to share and we can add it to the directory.
