Codex First

Hard gate

Autoreview exception: always prefer Codex-backed $autoreview, independent of ANTHROPIC_BASE_URL, router state, or harness. Reviewing a frozen bundle is not hands-on self-delegation. Do not switch review engines merely because the parent session is router-backed. This exception takes precedence over the gate below.

For direct hands-on delegation, use this skill only when the active agent is Claude Code and ANTHROPIC_BASE_URL is either unset or its URL host is neither loopback nor gorillaclaw.sheep-coho.ts.net.
