LogBear

AI coding agents can't see your dev server. They edit code, your server throws in another terminal, and the agent says "done, fixed it." Put logbear in front of your command (logbear npm run dev). Your terminal behaves exactly as before. LogBear records every run locally, and when your agent tries to finish with unread errors, it's stopped and handed the real error. Free, MIT, no account, no network calls. macOS.
