LinkedIn's Multi-Agent Code Review: 79K Weekly Comments, 63.9% Accepted
LinkedIn now reviews pull requests across ~10,000 repos with a multi-agent AI system that posts ~79,000 comments a week, most of them before a human reviewer ever opens the PR. An automated acceptance pipeline over 5,230 sampled comments found 63.9% of suggestions were actually adopted, rising to 80% for logic errors. The hard part wasn't generating comments; it was grounding them in the diff, filtering low-signal noise, and encoding each repo's tribal knowledge.
