Peer Review

Use a second AI agent to review and challenge the first agent's work. The peer reviewer exists to find what the builder missed -- not to agree, not to be polite, and not to rubber-stamp. This is the single most effective quality gate you can add beyond automated tests.

Core Principle

The peer reviewer's job is to find what the builder missed, not to agree.

A review that says "looks good" is a wasted review. The peer review model should be given explicit instructions to be critical, to challenge assumptions, and to look for what is not there rather than what is.
