Orchestrate multiple coding-agent CLIs (Claude Code, OpenAI Codex, Google Gemini, GitHub Copilot, Qwen Code) as one fleet through the quintet entry point. Use proactively when running several of these AI CLIs at once, when spinning up a multi-agent CLI worker team in tmux, for fanning a single prompt out to many models, or when debating or reviewing across models. Trigger on "quintet", "run codex and gemini and copilot", "orchestrate CLI agents", "ask all the models", "AI debate", "multi-model review". Not for single-model edits or generic multi-agent frameworks unrelated to the quintet CLIs.
