What it is

Get better code behavior by adding andrej-karpathy-skills to your LLM project.

Real use case example

"A founder building a Claude Code project wants to improve their LLM's coding behavior. They add the andrej-karpathy-skills and create a CLAUDE.md file with a list of coding pitfalls to avoid. After implementing the suggestions, their LLM produces more accurate and efficient code. The founder now achieves better results in their project development cycle."
