For those starting with AI coding, I just shared my CLAUDE.md (also works with Gemini and Codex BTW - see how-to). Since working with this my efficiency went way up. A lot of ideas come from @garrytan & @karpathy, while others are mine from my own experience.
Make sure to personalize it and add/remove what makes sense for you. And please LMK if you have ideas to make it better, always happy to learn more :)
