<blockquote cite="https://claude.dev/blog/solving-code-review-at-anthropic/"><p>We think "did a human read the code?" is an imprecise proxy for "what could go wrong with this change, and which check—automated or human—is the right one to catch it?"</p> <p>Asking that question also changed <em>when</em> review happens. Before, review was a gate at the end of the road: write the code, open a PR, wait for your colleague.</p> <p>Now, review runs continuously, more like spellcheck while you write. Most changes have been reviewed and fixed by Claude at least once before a human is asked to look. Thi
