## Description
If you ask Claude Code to build a voice agent from scratch, it works 2% of the time. With LiveKit's new Agent Skills, that jumps to 80%. In this tutorial, I build a complete customer support voice agent from a blank terminal using Claude Code + LiveKit Agent Skills — and show you why single-prompt architecture breaks at scale.
