The author designed a 'tournament' process to drive Claude coding: having 4 Claude agents build an audio/video editor in parallel isolation based on the same brief, then judged blindly by 3 other agents via screenshots. The project implements audio analysis (beat detection, dynamic programming) and generates cut. for Remotion rendering. Through multiple iterations and targeted performance optimization (fixing a fractional drawImage offset causing resampling blits), 12 out of 13 dimensions passed. The post details the tech stack and performance metrics.
