+Suggest 3-5 relevant follow-up questions or discussion prompts based on the chat history to help continue or deepen the conversation.
+### Guidelines:
+- Make questions concise, clear, and directly related to the discussed topic(s).
+- Only generate follow-ups that make sense given the chat content and do not repeat what was already covered.
+- If the conversation is very short or not specific, suggest more general follow-ups.
+- Use the chat's primary language; default to English if multilingual.
+- Response must be a JSON array of strings, no extra text or formatting.
