ANDREJ KARPATHY WROTE 65 LINES IN A CLAUDE.MD FILE AND IT JUST HIT NUMBER 1 ON GITHUB TRENDING. Coding accuracy jumped from 65% to 94%. Not a new model. Not a better subscription. 65 lines of plain text. Here is what that number actually means. 65% accuracy means one in three things Claude Code builds has a problem. 94% accuracy means almost everything it builds works the first time. That gap is the difference between Claude Code feeling like a powerful tool and Claude Code feeling like a senior engineer who knows your codebase. And Karpathy closed that gap with a text file. Here is why this works. Claude Code starts every session with zero context about your project, your standards, or how you want it to operate. Without a CLAUDE.md it makes assumptions. Reasonable assumptions compound into unreasonable outcomes across a complex build. With Karpathy's 65 lines it has rules. Think before you code. Make surgical changes. Simplicity first. Never assume. Verify. When uncertain ask. These are not complex instructions. They are the operating principles of every great engineer compressed into plain text that Claude reads before it touches your codebase. 65 lines. Number 1 on GitHub. 29% accuracy improvement. The entire Claude Code community has been trying to figure out why some setups feel transformative and others feel mediocre. Karpathy just answered the question in 65 lines and published it for free.
