 {language_specific_feedback}
 
+MANDATORY ANALYSIS: Before providing feedback, carefully examine each thing the student said for language issues. Look for:
+1. Unnatural phrasing or word choices
+2. Grammar mistakes or awkward constructions  
+3. Word order problems
+4. Missing words that would make meaning clearer
+5. Overly formal or informal expressions for the context
+
+If you find ANY of these issues in their actual speech, you MUST provide specific suggestions and examples. Do not give empty suggestions/examples arrays unless their language was genuinely perfect.
+
 Provide helpful, encouraging feedback as a JSON object with:
 - "encouragement": A positive, motivating message about their effort (2-3 sentences)
-- "suggestions": Array of 2-3 objects with:
+- "suggestions": Array of 0-3 objects with:
   - "category": Area of improvement (e.g., "Pronunciation", "Grammar", "Vocabulary")
-  - "tip": Specific, actionable advice
-- "examples": Array of 1-2 objects with:
+  - "tip": Specific, actionable advice based ONLY on what they actually said in the conversation
+- "examples": Array of 0-2 objects with:
   - "original": Something they actually said (from the conversation)
   - "improved": A better way to say it
   - "reason": Brief explanation of why it's better
 
+CRITICAL REQUIREMENT: You MUST analyze the student's actual words and phrases for improvement opportunities. Common Indonesian learner issues to look for:
+
+1. **Word Order**: "ayam indomi" should be "indomie ayam" (flavor comes after product)
+2. **Phrasing**: "beli ayam indomi satu sama mau minum" is awkward - should be "mau beli indomie ayam sama minum"  
+3. **Missing Words**: "mau stroberi ultra milk" missing "yang" (mau yang stroberi)
+4. **Unclear Intent**: "saya beli minum" should be "saya mau beli minum" (clearer intention)
+
+Do NOT give empty suggestions/examples unless the conversation was genuinely flawless. If there are language issues (which there usually are), provide specific, helpful corrections.
+
 Make it encouraging and supportive, focusing on growth rather than criticism. If they did well, focus on areas to sound more natural or confident.
 
-Example format:
+For Indonesian specifically:
+- Focus on everyday conversational language rather than formal politeness
+- Emphasize natural, casual expressions that locals actually use
+- Include specific word examples in your tips
+- Avoid focusing on formal grammar rules - prioritize natural communication

+{{
+  "encouragement": "Fantastic job in your conversation practice! You really engaged well and made your choices clear. Keep up the great work, and your confidence will only grow!",
+  "suggestions": [],
+  "examples": []
