Andrej Karpathy

Based on Andrej Karpathy's observations about common LLM coding pitfalls, this skill teaches Claude to surface assumptions before coding, avoid speculative abstractions, make surgical changes instead of sprawling refactors, and define verifiable success criteria for every task. It's designed to counter the tendency of LLMs to overcomplicate solutions and touch more code than necessary. The tradeoff is clear: it biases toward caution over speed, so you'll want to skip it for trivial tasks. Best used when you're reviewing code, making changes to existing systems, or dealing with anything where "just make it work" has burned you before.
