# Refactor Method to Reduce Cognitive Complexity ## Objective Refactor the method `${input:methodName}`, to reduce its cognitive complexity to `${input:complexityThreshold}` or below, by extracting logic into focused helper methods. ## Instructions 1. **Analyze the current method** to identify sources of cognitive complexity: - Nested conditional statements - Multiple if-else or switch chains - Repeated code blocks - Multiple loops with conditions - Complex boolean expressions 2. **Identify extraction opportunities**: - Validation logic that can be extracted into a separate method - Type-specific or case-specific processing that repeats - Complex transformations or calculations - Common patterns that appear multiple times 3. **Extract focused helper methods**: - Each helper should have a single, clear responsibility - Extract validation into separate `Validate*` methods - Extract type-specific logic into handler methods - Create utility methods for common operations - Use appropriate access levels (static, private, async) 4. **Simplify the main method**: - Reduce nesting depth - Replace massive if-else chains with smaller orchestrated calls - Use switch statements where appropriate
