You might be misunderstanding what a CLAUDE.md is. It’s not about fighting the model, rather it’s giving the model a shortcut to get the context it needs to do its work. You don’t have to have one. Ours is 100% written by Claude itself.
That's not the same thing as adding rules by yourself based on your experiences with Claude.
