Review moved before the PR: Claude must prove completion with tests; Boris Cherny cites 2-3x quality gain

From Addy Osmani's thread: where did the review go? Before the pull request. Claude doesn't get to say it's done — it has to show it: run the tests and the build, match the screen to the design. Then a fresh, context-free agent reads the diff.

Boris Cherny, who built Claude Code, puts the quality gain at 2 to 3x.
