External review service management

External-mode documentation is now split by task so setup prerequisites are not hidden inside OS service definitions.

Start here

  1. Read How external mode works.
  2. Complete Set up external mode, including the one-off worker check.
  3. Register the worker for macOS or Linux.
  4. Use Operations and troubleshooting for upgrades, status, failures, and disabling the service.

The old one-page service guide mixed configuration, executable discovery, authentication, and service registration. These pages preserve the same launchd and systemd --user workflows while making the required order explicit.
