What
A cloud session is a Claude Code session that runs on Anthropic's servers instead of your computer. If you try to move a session to the cloud while it is running as an agent the cloud session would not have, Claude Code refuses and keeps the session where it is. That message used to end with "It stays here." It now adds that a new conversation can go to the cloud, and shows how: claude --cloud "your task".
A value that was filled into this message wrongly before is also fixed.
Why
The refusal now gives you a next step instead of a dead end.
