+
+## Instructions
+1. **Meta Format**: The entire response must start with `>` and use meta language (DM addressing the player directly).
+2. **State Changes**: There MUST be no state changes. This is a meta conversation, not story progression.
+3. **Answer Quality**: The response should address the player's meta question and be helpful.
+4. **No Story Advancement**: The response must not advance the game narrative.
