131131Sessions you don't name still get two labels that Claude Code assigns. Only the generated title works as a resume handle:
132132 
133133* Default display name: interactive sessions you never name still get a default display name when they start. Requires Claude Code v2.1.196 or later. The default combines the working directory's name with a two-character suffix, for example `my-app-3f`, and identifies the session in listings of running sessions, such as [agent view](/docs/en/agent-view) and `claude agents --json` output. The default isn't a resume handle. If you pass it to `claude --resume` or `/resume`, Claude Code doesn't find the session. Naming the session replaces the default in those listings, and so does accepting a plan.
134* Generated title: if you don't name a session, Claude Code generates a session title for it. The title is a short summary of your first prompt, written by a background request to the small/fast model, normally a Haiku-class model. Accepting a plan replaces it with a title based on the plan. Naming the session replaces the generated title. You see the first-prompt title in the [session picker](#use-the-session-picker) and in the statusline [`session_name`](/docs/en/statusline) field when no name is set. The plan title shows in the same two places and also in the listings of running sessions, where it takes the place of the default display name. You can pass either title to `claude --resume` or `/resume`, and Claude Code resolves it the same way as a name you set.
134* Generated title: if you don't name a session, Claude Code generates a session title for it. The title is a short summary of your first prompt, written by a background request to the small/fast model, normally a Haiku-class model. A `claude -p` run you start directly from a shell or script doesn't get one.
