openclaw worker

openclaw worker is the restricted runtime entry point for a cloud worker orchestrator to launch inside a prepared worker environment. It is not a general-purpose command for manual worker registration. The gateway installs the matching OpenClaw bundle and opens the host-key-pinned reverse SSH tunnel. The worker launcher starts this command with a prepared assignment. The command connects through the tunnel-forwarded local socket and admits as the dedicated worker role.

​
Launch contract

The command reads exactly one bounded JSON launch envelope from standard input. The envelope carries the local socket location, minted worker credential, bundle and protocol identity, owner epoch, and the single assigned session and turn. The credential is never accepted through command-line arguments, and this page intentionally provides no credential or hand-authored envelope example. Admission fails closed if the envelope is invalid, the credential is rejected, the bundle or protocol features do not match, or the session and owner epoch are no longer current. Operators should start workers through the cloud worker orchestrator rather than invoke this entry point directly.

​
Runtime boundary

The process runs the normal embedded agent loop with a restricted backend:
  • The read, write, edit, apply_patch, exec, and process coding tools run locally in the worker workspace.
  • Model calls use the gateway inference proxy. No local model auth profile is loaded.
  • Transcript writes use the gateway transcript-commit RPC.
  • Streaming and tool lifecycle updates use the gateway live-event RPC.
  • Only the assigned session and turn are accepted.
Worker mode does not start channels, Gateway HTTP surfaces, or plugin auto-start beyond the assigned session toolset. It uses a throwaway state directory and has no standing provider or forge credentials. Worker-to-worker session dispatch is not exposed in this mode. Placement and dispatch remain gateway-owned: an operator can dispatch an existing local, managed-worktree session through the Gateway, while a worker process cannot dispatch itself or another worker. The prepared assignment carries the transcript context, accepted base leaf, commit sequence, and live-event cursor. On a tunnel reconnect, the process re-admits with the same credential and owner epoch, retains the accepted transcript base, replays its unacknowledged live-event tail, and reattaches an in-flight inference turn with the same identity. The terminal inference message is authoritative if streamed deltas were missed. A superseding owner epoch fences the process and causes a clean exit. A stale-base-leaf transcript rejection fail-stops the current run. Worker mode does not retry the rejected sequence against a different leaf, so no duplicate commit is produced; any still-uncommitted in-memory tail from that run is lost. Relaunch belongs to the milestone-3 placement owner, which must create a fresh assignment from the gateway’s authoritative transcript and commit ledger. Likewise, a gateway process restart terminates a pending inference turn with a provider error; only a tunnel or worker WebSocket reconnect can reattach to an active same-process inference stream.
