I have done the vast majority of my agentic coding work under 128k on a 256k context model and when I cross 128k, all I do is just ask for a handoff prompt to feed back into the next session. I do this because I was told the quality degrades as the context fills up and I fundamentally dislike random compaction, I don't even know what compaction does, it is completely intransparent.
