Do you maybe want to give us users some hints on what to compact and throw away? In codex CLI maybe you can create a visual tool that I can see and quickly check mark things I want to discard.

Sometimes I’m exploring some topic and that exploration is not useful but only the summary.

Also, you could use the best guess and cli could tell me that this is what it wants to compact and I can tweak its suggestion in natural language.

Context is going to be super important because it is the primary constraint. It would be nice to have serious granular support.
