What
Claude can now end a conversation itself using an EndConversation tool, surfacing clear messaging to the user.
Details
- When the model invokes
EndConversation, users see "Claude ended this conversation. Start a new session (or /clear) to continue." - A transcript entry with
"type":"ended-by-model"is appended so the event is recorded - Sessions ended by the model are tracked separately from user-terminated sessions in fleet state
Evidence
End-of-conversation user message (search for "Claude ended this conversation") — mP_() at line ~745953 and Nnt() at line ~504796
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
