147147Sessions you don't name still get two labels that Claude Code assigns. Only the generated title works as a resume handle:
148148 
149* 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.

150150* 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.

152152 Accepting a plan replaces the generated title with a title based on the plan. You can pass either title to `claude --resume` or `/resume`, and Claude Code resolves it the same way as a name you set.
