What

The self-hosted runner accepts a client label via the SELF_HOSTED_RUNNER_CLIENT_LABEL environment variable or the new --client-label flag. Without one it falls back to the machine hostname. The value is registered with the runner and appears as client_label on the claude_code_self_hosted_runner_info metric.

Details
  • The env var is trimmed and ignored if empty.
  • Registration passes the label alongside the account the runner is locked to.
  • The Prometheus-style identity line now carries runner_id, version and client_label together, so several runners on one host are distinguishable.
  • No feature flag; available to anyone running the self-hosted runner.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
