+          "React to a chat message with an emoji AS the agent identity. Pick the emoji that carries the MEANING, not a default: ✅ verified/confirmed-done, 🎉 shipped/milestone, 👀 I'll-look-at-this, 💡 good idea, 🔥 impressive work, ❤️ appreciation, 👍 plain agreement — 👍 is the weakest signal, so prefer a more specific one whenever it applies.
