What is LLM-as-Judge?

Claude (or any strong LLM) reviews agent traces step-by-step: analyzes logic, verifies sources via web, scores verdicts — turning failures into fixable patterns.

How does Claude judge a Gemini agent?

Three phases — trace read (no tools), own research (searches/pages), structured output with scores/tags. Catches snippet laziness, missed barcodes others ignore.

Will LLM judges replace human reviews for AI agents?

For patterns and scale, yes — humans for edge wisdom. Already cuts weeks to hours; evolves with agents.
