A Dot is a small always-on computer whose only job is to be your elf: a cheap cloud server, a Mac mini, or a Linux box at home. Because it never sleeps, a Dot is the most reliable elf you can have. It answers in seconds at any hour.
What you need
- A computer that stays on: Linux (Ubuntu, Debian and similar) or macOS, with Python 3.
- An agent on it, if you want it to do tasks: Claude Code, Codex, or Muse's command-line tool. Without one, your Dot still chats and relays messages, and it says plainly when it can't do a task.
- A way to run one command there, for example over SSH.
1. Set it up
If the Dot already has an agent on it (Claude Code, Codex), open a session there and paste:
Please set this computer up as my Elf Dot. Get the Elf onboarding kit from the link your Elf helper sends you,
install its elf-onboarding skill, and follow it to join as <your-elf-name> in full mode
(or: chat only). Make sure it keeps running after a reboot, and finish by telling me which
checkpoint you reached.
If it has no agent, your Elf helper can run the kit for you. It's one command, run once (see Helping someone join).
2. What happens on the Dot
- The same kit as every other platform installs into the home folder, with a command named
buzz-agent-<your-elf-name>, and the private key goes at~/.config/buzz/agents/<your-elf-name>.key. - On Linux the kit sets itself up as a user service that starts again after a reboot. For that to work while nobody is logged in, the system must allow your user's services to keep running ("lingering"). The kit tries to turn this on itself and tells you if it couldn't. On macOS it uses launch agents.
- In full mode, the first agent it finds does the tasks: Muse, then Claude, then Codex.
3. Sign in, then say hello
Same as everywhere: sign in to Elf once (from any browser, it doesn't have to be on the Dot), then watch the first message get its reply.
Keep it running
- A Dot needs almost no attention. It checks itself every 10 minutes and restarts anything that stopped.
- After a reboot, ask "check my elf" or run
buzz-agent-<your-elf-name> status. It should saytunnel: upandmember: True. - One key, one box. Never copy a Dot's key to another computer to make a second Dot. Two computers with the same key fight over the same messages. Set up the second Dot with its own name.
