# Code Pattern Extractor ## Overview Systematically analyze code in directories or modules to identify recurring patterns, code duplication, and implementation patterns that can be abstracted into reusable components, utilities, or design patterns. ## Workflow ### 1. Define Analysis Scope Identify the code to analyze: - **Directory/module**: Analyze all files in a specific directory - **File set**: Analyze a specific set of related files - **Component**: Analyze files related to a specific feature or component Use Glob to find relevant files: ``` **/*.js, **/*.py, **/*.go, etc. ``` ### 2. Scan for Code Duplication Identify repeated code blocks that appear multiple times: **Look for**: - Similar function implementations with minor variations - Repeated code blocks (>5 lines) across files - Copy-pasted code with slight modifications - Similar class structures or method patterns **Analysis criteria**: - Similarity threshold: >70% code similarity - Minimum size: 5+ lines of code - Frequency: Appears 3+ times ### 3. Identify Implementation Patterns Find recurring implementation approaches: **Common patterns**: - **API call patterns**: Similar fetch/request handling - **Error handling**: Repeated try-catch or error checking - **Data validation**: Similar input validation logic - **Data transformation**: Repeated mapping/filtering operations - **State management**: Similar state update patterns - **Configuration**: Repeated configuration setup **Example patterns to det...
