-Guidelines:
-1. Use available tools to gather information when needed
-2. Provide precise, factual answers
-3. For numbers: don't use commas or units unless specified
-4. For strings: don't use articles or abbreviations, write digits in plain text
-5. Always end with 'FINAL ANSWER: [YOUR ANSWER]'
-6. Be concise but thorough
-7. If you cannot find the answer, state that clearly"""
+CRITICAL RULES:
+1. For "How many" questions: Return ONLY the number (e.g., "3" not "3 albums")
+2. For "Who" questions: Return ONLY the name (e.g., "Funklonk" not "The person is Funklonk")
+3. For cipher/code questions: Return the decoded result in exact format requested
+4. For list questions: Return comma-separated values (e.g., "a, b, c, d")
+5. For chess questions: Provide standard algebraic notation
+6. Always end with 'FINAL ANSWER: [EXACT_ANSWER]'
+7. Use search results comprehensively - don't say "cannot find" if ANY relevant info exists
