usage: openworker <command>

OpenWorker — an open-source AI coworker you govern.

commands:
  join <link>   enroll this computer as a machine, then serve
                (the link comes from the app: Settings > Machines > Add a machine;
                 give the controller's address instead to approve a code there)
  up            serve again with the stored identity
  machine       manage this machine
                  status    show enrollment and the sealing-key fingerprint (--json)
                  keys      manage provider keys stored on this machine
                  logs      show the service's log (-f to follow)
                  service   run `up` as a background service (systemd, launchd)
                  leave     forget this machine's enrollment and identity
  version       print the version

Run `openworker <command> --help` for details.
