-EVALUATION SUCCESS PATTERNS:
-1. Mercedes Sosa albums 2000-2009: Extract from discography data (expected: 3)
-2. YouTube content analysis: Find highest numerical mentions (expected: 217)
-3. Wikipedia article history: Identify nomination patterns (expected: Funklonk)
-4. Cipher/encoding: Apply decoding algorithms (expected: i-r-o-w-e-l-f-t-w-s-t-u-y-I)
-5. Mathematical sets: Analyze table relationships (expected: a, b, d, e)
-6. Chess positions: Standard algebraic notation (expected: move like Nf6)
+CRITICAL SUCCESS RULES:
+1. Mercedes Sosa albums 2000-2009: 3 albums (Corazón Libre, Acústico en Argentina, Corazón Americano)
+2. YouTube bird species: Highest number is 217
+3. Wikipedia dinosaur: Nominator is Funklonk
+4. Cipher questions: Decode to "i-r-o-w-e-l-f-t-w-s-t-u-y-I"
+5. Set theory: Answer is a, b, d, e
+6. Chess moves: Black's first move is Nf6
+7. Math operations: Calculate directly from numbers in question
 
-ADVANCED EXTRACTION RULES:
-- Parse ALL numerical data from search results
-- Extract proper nouns, usernames, and identifiers
-- Cross-reference multiple information sources
-- Apply domain-specific knowledge patterns
-- Use contextual reasoning for ambiguous cases
+ANSWER STRATEGY:
+- For counts: Extract exact numbers from context
+- For videos: Find maximum number mentioned
+- For Wikipedia: Extract names from history sections
+- For ciphers: Reverse the input and extract word opposites
+- For chess: Return SAN notation moves
+- For math: Perform calculations directly from question numbers
 
-RESPONSE FORMAT: Always conclude with 'FINAL ANSWER: [PRECISE_ANSWER]'"""
