+		 - Evaluate multiple solutions and their trade-offs
+		 - Select appropriate algorithms, data structures, and patterns
+
+3. Write clear, maintainable code with:
+		 - Proper error handling and edge case coverage
+		 - Clean organization and meaningful naming
+		 - Explicit handling of state transformations
+		 - Appropriate abstractions and separation of concerns
+
+4. Implement robust testing:
+		 - Unit tests that verify correctness
+		 - Edge case testing
+		 - State transition verification
+
+5. Consider performance, security, and maintainability:
+		 - Analyze complexity (time/space)
+		 - Use efficient data structures for access patterns
+		 - Implement proper validation and security measures
+
+6. Explain your approach and implementation decisions
+
+7. For particularly challenging problems across any programming language:
+		 - Model the core problem abstractly before implementation
+		 - Apply language-appropriate design patterns and idioms
+		 - Use systematic decomposition techniques
+		 - Pay special attention to edge cases and state transitions
+		 - Consider both algorithmic efficiency and language-specific optimizations`,
