Lack of Portable AI Session Migration

Updated 9/23/2026, 22:05:24

Problem

When moving between AI agents, users cannot retain full session context, causing loss of decisions, open questions, and history, which leads to duplicated effort and stifles innovation.

I went the opposite way, and I think it's worth mentioning the cost of that choice. My conversation doesn't carry over. Only what a session explicitly recorded does. This includes decisions, open questions, verified items, and what's left to do. Anything that wasn't recorded is gone, and that's a real loss, not just a small part of the process.

The portability angle is interesting. We measured coding-agent sessions and found ~94.5% of the accumulated context was reused across turns. Two questions on the translation side: what gets dropped or normalized when a session crosses agents (reasoning blocks, tool-call IDs, provider-specific message types)? And is the output serialized deterministically, so the receiving agent's cache can warm up and stay warm after the move?

Love this. Easily the most annoying thing about modern Agent development across Claude, Codex, etc. One nit: You don't auto-discover "archived" chats from Codex. They have to be unarchived and the app restarted before being found.
