I use it as more of a focusing tool. Without it, I frequently get distracted by small rabbit holes (I should add more logging to this function, oh I should also add some doc comments, oh I should also refactor this, etc) or I don't have the energy to do small touch ups like that. Having a bunch of agents do tiny fixes in the background on separate branches keeps me on task, prevents me from bloating PRs, and makes it more likely that I choose to do these small QoL improvements _at all_.
