-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
+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)
 
-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
+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
