Andrej Karpathy identified three common mistakes Claude makes in coding tasks: making wrong assumptions, over-engineering solutions, and making orthogonal edits. He distilled these observations into four rules: Think Before Coding, Simplicity First, Surgical Changes, and Goal-Driven Execution. These rules are implemented in a single 80-line Claude.md file that can be installed with one command and helps Claude produce more reliable code by preventing common pitfalls.
