+        f"2. Do not include any additional text, comments, formatting instructions, or explanations.\n"
+        f"3. Ensure proper syntax:\n"
+        f"   - All keys and string values must be enclosed in double quotes (\"\").\n"
+        f"   - No trailing commas.\n"
+        f"   - Properly close all braces (`}`) and brackets (`]`).\n"
         f"4. Validate the JSON before returning it to ensure it is syntactically correct and complete.\n"
-        f"5. Do not use any extra characters like ◀ or </s>.\n"
+        f"5. Do not include any extra characters, such as ◀, ▶, or ```.\n"
+        f"6. If there is insufficient data to generate meaningful content, generate a placeholder JSON object with empty values, e.g.,\n"
+        f"{{\n"
+        f"  \"title\": \"\",\n"
+        f"  \"sections\": []\n"
+        f"}}\n"
+        f"7. The response must always conform to this exact JSON structure, with no deviations."
