Cross-agent planning and review between Claude Code and Codex. One agent creates an implementation plan, the other reviews it, iterating until approved. Use when the user wants a second opinion on a plan, wants two AI agents to collaborate, or wants Codex to review or create a plan. Also auto-invokes when you have just generated a non-trivial implementation plan (multiple files, architectural decisions, or significant changes) and auto-review is enabled.
