What
A title you set for a session is now saved to its own small JSON file next to the session transcript, and removed from that file when you clear the title. Session summaries read the title back from that file when the recent conversation history does not already carry one.
Details
- The new file,
custom-title.json, joins the other per-session side files Claude Code keeps (ccr-tip.jsonandprecompact.json). - A helper scans the transcript backwards for the last user or assistant timestamp when writing the record.
- The older path that read the title inline from either of two conversation records is gone, along with the inline handler for clearing a session title.
- Live in this build, no flag.
