123123A session answers to the name you set with the [`/rename`](/docs/en/commands) command or the [`--name`](/docs/en/cli-reference#cli-flags) flag.

125When you rename a session, or start or resume an interactive one, with a name another live session on this machine already uses, Claude Code leaves the name with the session that already has it and [renames yours to a variant](/docs/en/sessions#name-your-sessions). Sessions can still share a name, for example when one of them runs an earlier version of Claude Code or the shared name is one Claude Code generated. Unless this session is connected to Remote Control, Claude Code shows each local session's working directory in the `/list-agents` output, so you can tell same-named sessions apart when they run in different directories. Claude addresses the message in one of two ways, depending on how many live sessions answer to the name:

128128* **Several sessions share the name, or Claude Code couldn't check everywhere your sessions run**: Claude adds a short identifier to each row of its listing and uses the identifier in the address.
