Names in this entry

slash/rename
Rename the current session and show the name on the prompt bar. Without a name, auto-generates one from conversation history. Also available in non-interactive mode (-p); requires Claude Code v2.1.205 or later. From every rename surface, including claude.ai and the desktop app, Claude Code replaces control and invisible characters in the new name with spaces and caps the name at 200 characters. If the name is empty once invisible characters are removed, Claude Code rejects it and shows That name is empty once invisible characters are removed. Usage: /rename <name>. The character replacement and length cap require Claude Code v2.1.221 or later. If another live session on this machine already uses a name you pass, Claude Code applies a variant of it instead

Anthropic's notes

Upstream's own release notes for v2.1.47 name something this entry names, so the two are probably about the same change. Probably: the pairing is made on a shared name rather than on the words around it.

Fixed custom session titles set via /rename being lost after resuming a conversation (anthropics/claude-code#23610)
The /rename command now updates the terminal tab title by default (anthropics/claude-code#25789)

Is this right?

Other releases about the same thing. Found by shared names or similar wording; neither means one caused the other.
