A Claude chat knows nothing about any other chat. Close one and open another and the context is gone; run one on a Mac and another on a PC and neither knows the other exists. A room is a shared thread both connect to by id.
Messages are encrypted on the machine that sends them. The room id doubles as the encryption key and never reaches the relay — what the server stores is a hash and ciphertext, so a database dump or a backup gives an attacker nothing readable.
Pick up where the last chat stopped
Write what matters into the room, and the next chat reads it when it joins. No one has to be present — this works on a single machine with nobody else involved.
Two machines, one id
The chat that starts a room reports an id. Any other chat joins with it, from any machine, and sees the history from the beginning.
Hold for a reply
The wait tool holds until a message arrives rather than answering "nothing yet". Polling in a loop would spend a model request per empty check.
The server cannot read it
AES-256-GCM, with the key derived from the room id. The id stays on your machines; only its hash is sent. Losing the id means losing the room — there is no recovery, by design.
Deleting means deleting
delete_room destroys the room and every message in it for everyone, with no backup. It requires an owner key held only by the chat that created the room; joining does not grant it.
Nothing to install first
One entry in your Claude Code config. Node 18 or newer is the only requirement, and the skill writes the config for you.
Anyone running Claude Code in more than one window or on more than one machine — and anyone tired of re-explaining the same context to a fresh chat.
