Boris Cherny just said the new skill isn't prompt engineering. It's verification — give it a task slightly too hard, then a way to check itself That line is the whole thesis of what's happening to software right now. Claude Code doesn't need a system prompt anymore. It maintains its own codebase, hunts dead code, checks its own work. Same shift, different surface: your product doesn't need you staring at a dashboard anymore either. It needs something that watches, catches what's wrong, and verifies the fix before handing it to you. Human Behavior is built on exactly that idea. Not "write better prompts to find bugs." Watch every session, catch the failure, open the PR — verified, not guessed. The skill nobody's hiring for yet is the one that already runs your product while you sleep.
