With 1.129 if I run code agent I get this output:

ubuntu@copilot-testing:~$ vscode-linux-x64-1.129.0/bin/code agent
[2026-07-18 10:59:47] info Agent host supervisor logging to /home/ubuntu/.vscode-server/cli/agent-host-stable.log

  Visual Studio Code Agent Host v1.129.0  ready in 62ms

  ➜  Local:    ws://localhost:35893?tkn=608ef607-46e4-4511-871e-db7c5c42e281
  ➜  Network:  use --host to expose
  ➜  Manage:   code agent ps  |  code agent kill

It says I can use code agent ps to manage the host, however that produces this error:
