What's Wrong?

Environment:

Claude Code Extension: 2.1.76
IDE: Cursor (linux-x64)
Claude Code CLI: 2.1.76
OS: Ubuntu Linux 6.8.0 (AWS)
Issue:
The session history dropdown in the IDE previously showed the first user message as the session label, making it easy to identify past conversations. Now, when I close a conversation and later go back to find it in the history, the label shows the last message instead. Since conversations typically end with "ok", "thanks", "got it", the entire history list becomes indistinguishable and unusable.

I'm not sure which version introduced this change, but it's currently broken on 2.1.76.

What Should Happen?

The session history dropdown in the IDE previously should show the first user message as the session label.
