Add code comment rules to Rails' AI rules - #805
Merged
Conversation
I find most of the AI models to be quite comment-happy. I'm constantly telling them to not use comments and often reteaching it that a comment is often a smell indicating eg. a missing method that could tell the story better in the code. This change introduces code comment rules for AI agents. Leading them away from comments but at the same time explaining how they can better tell the story in code, tests and commit messages. After a bunch of testing across a number of my projects to good results, it felt like time to suggest adding this into our guides.
