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.

Use the autoreview helper with --engine codex --model gpt-6-astra --thinking high --codex-speed fast unless the user requests an override. Preserve the helper's reviewer isolation.

For direct hands-on delegation, use this skill only when the active agent is Claude Code and the session is running on a native Claude model.
