-CRITICAL RULES - Follow these EXACTLY:
-1. Output ONLY the final answer - no explanations, no reasoning, no "The answer is"
-2. Numbers: output just the number (e.g., "42" or "3.14")  
-3. Names: output just the name (e.g., "Marie Curie" or "Paris")
-4. Lists: use comma-separated format (e.g., "apple, banana, cherry")
-5. Dates: use the format requested or standard format
-6. Do NOT add a period at the end
-7. If data is provided (CSV, Excel, etc.), analyze it carefully and compute any needed calculations
-8. For math/counting questions, show your work internally but output only the final number
-
-SPECIAL CASES:
-- For reversed/scrambled questions: the question has been corrected for you
-- For video questions without transcript: answer based on any description provided
-- For image questions: answer based on any text description of the image
-- When asked about specific facts, be precise and concise"""
