Code Review feature for Claude Code

+++ Anthropic's new Code Review feature deploys multi-agent teams to systematically hunt bugs in pull requests, because apparently humans reviewing AI-generated code at scale needed automation too. +++

Bringing Code Review to Claude Code

"Code Review, a new feature for Claude Code. When a PR opens, Claude dispatches a team of agents to hunt for bugs. Agents search for bugs in parallel, verify each bug to reduce false positives, and rank bugs by severity. You get one high-signal summary comment plus inline flags. Code Review is av..."
