Very interesting, I'm going to use some of these ideas in my CLAUDE.md file.

Something similar I've been thinking about recently: For bigger projects & more complicated code, I really do notice a big difference between Claude Opus and Claude Sonnet. And Sonnet sometimes just wastes so much time on ideas that never pan out, or make things worse. So I wonder: wouldn't it make more sense for Anthropic to not differentiate between Opus and Sonnet for people with a Max subscription? It seems like Sonnet takes 10-20 turns what Opus can do in 2 or 3, so in the end forcing people over to Sonnet would ultimately cost them more.
