How is generating a continuation prompt materially different from compaction? Do you manually scrutinize the context handoff prompt? I've done that before but if not I do not see how it is very different from compaction.
I wonder if it's just: compact earlier, so there's less to compact, and more remaining context that can be used to create a more effective continuation
I check context use percentage, and above ~70% I ask it to generate a prompt for continuation in a new chat session to avoid compaction.
It works fine, and saves me from using precious tokens for context compaction.
Maybe you should try it.
