How to Add Multi-Model AI Code Review to Claude Code in 30 Seconds

You know that moment when Claude reviews your code, gives it the green light, and then two days later you're debugging a production issue that three humans would have caught immediately? Single-model AI code review has a blind spot problem. Each model was trained on different data, has different failure modes, and holds different opinions about what "correct" looks like. When you only ask one AI, you're getting one perspective - and that perspective has systematic gaps. Multi-model consensus code review flips the script.
