I let agents read their own pre-compaction history often, as well as history form other sessions. I use both Codex and Claude Code. The main friction right now is keeping an overview of the sessions. Sessions don't have a max length for me. I run them as long as I want, but I keep session scope somewhat limited, usually to one discipline (e.g. software, CAD, electrical, sales, website). But I'll switch to the GUI apps soon, because they seem to have reached parity over the terrible CLIs that I use.
