Vibe-Coding Skills: Caveman, Karpathy Rules, and Engineering Guidelines
A curated selection of open-source AI coding skills that significantly improve the quality and efficiency of LLM-assisted development.
Caveman (GitHub) — reduces Claude's verbosity by up to 30%, saving tokens on expensive Opus models. Activated with a simple /caveman command, it makes the AI respond in terse, action-oriented phrases while maintaining task quality.
Karpathy Rules (GitHub) and Matt Pocock Skills (GitHub) — engineering guidelines that teach the AI to think before coding, prioritize simplicity, make surgical changes, and break tasks into structured checklists. These reduce hallucinations and circular debugging loops.
Key insight: the AI performs better when you describe the desired outcome rather than step-by-step instructions. Paradoxically, saying 'make it beautiful' often yields better results than micromanaging the implementation.
