Every four months or so we try getting hyped on agents for ~ a week. Up to this point the answer has always been a pretty solid "nope this sucks back to manual code." The agentically coded parts of the codebase that came from these trials are palpably more annoying than the rest. However, the current trial is going better than the last ones have (Fable 5.1 really is astonishing). On the other hand, each other trial started with a honeymoon so it's up in the air.
