What probably matters to you Section of the release
What
Commands that cannot run inside a cloud session now say why and give you the local command to run, instead of a generic refusal.
Details
Applies to /teleport , /session and /remote-control among others; for example /teleport returns text explaining that it pulls a cloud session into a terminal on your own machine, so it cannot run from inside this session, and gives claude --teleport <id>. The tailored text requires a known remote session id from CLAUDE_CODE_REMOTE_SESSION_ID . Without that id, the previous generic "/x isn't available in this environment." message is still used. Evidence
pulls a cloud session into a terminal on your own machine
Strings lifted out of the shipped bundle, so the claim above can be checked against them.

env CLAUDE_CODE_REMOTE_SESSION_ID Commands blocked in cloud sessions now tell you the exact local command to run instead.
Anthropic's note
Upstream's own release notes for v2.1.223 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.
Added a /teleport hint in cloud sessions showing how to continue locally with claude --teleport <session id>

Hard to understand Too vague Looks wrong Not relevant to me Too long Missing the detail I wanted Duplicate of another card
