Andrej Karpathy named the specific ways LLMs screw up code. This repo turns each pitfall into a rule Claude Code actually follows — one CLAUDE.md, four principles, no silent mistakes.

He says nothing. He writes one line. It works. An agent skill that stops your AI from over-building. Two hooks, one command. npm install -g @0xwilliamortiz/ponytail-improved ponytail

Your agent reads the rules. This checks whether it followed them. A ratchet turns one way. Complexity in your codebase goes down or stays flat, unless someone deliberately turns it the other way and writes down why.
