Rename Sessions Mid-Conversation with /rename

You don't have to name sessions before you start them. If a conversation turns out to be more useful than expected, rename it on the fly with /rename:

> /rename auth-refactor

The new name appears immediately in the prompt bar and your terminal title. It will also show up in the --resume picker the next time you want to return to this session:

claude --resume auth-refactor

This is handy when you start a session without a name and only realise mid-way that you'll want to return to it. Rather than trying to remember a UUID, just run /rename at the natural pause point before context gets lost.

It's also useful when juggling multiple windows — the terminal title updates immediately, so you can glance at your taskbar or tmux tab list and know which session is which without switching to it.

If you want to name sessions from the start instead, use the -n flag at launch:

claude -n "payment-integration"

/rename and -n both write to the same session metadata, so you can use either approach depending on whether you know the name upfront. The result is the same: a human-readable label in the --resume picker instead of a UUID.

Name or rename whenever the session becomes worth keeping — /rename takes two seconds and saves you hunting for UUIDs later.
