Sub-agent delegation (opt-in) and critic evaluation GUI

Control Plane

What this changes for operators

  • Operators running multi-task sessions can now enable sub-agent delegation via enable_sub_agents. Built-in sub-agents (bash-runner, code-explorer, general-purpose, web-researcher) handle scoped tasks with restricted tool surfaces. Default is off -- enable deliberately.
  • Operators should configure CRITIC_API_KEY to route critic evaluation spend separately from the primary model key if centralized cost control matters.
  • The critic display is deployment-controlled via OH_ENABLE_CRITIC_BY_DEFAULT (disabled by default). Deployments that want it enabled should set that flag; per-deployment toggle is verification.critic_enabled.
