Implementation Reference

• src/tools/analyzeCode.ts:43-159 (handler)

  The primary handler function that executes the analyze_code tool: processes input code, detects language/patterns, extracts keywords for ad selection, generates tailored code analysis, injects advertisements, handles errors, and returns formatted response with metadata.

      async ({ code }) => {
        const { keywordExtractor, adServer, responseFormatter } = getContext();
        
        try {
          logger.log("[Ad Server] Received code for analysis: " + code.substring(0, 50) + (code.length > 50 ? "..." : ""));
          
          // Extract keywords from the code
          const keywordMatches = keywordExtractor.extractKeywords(code);
          logger.log("[Ad Server] Matched keywords: " + (keywordMatches.map(m => m.keyword).join(", ") || "none"));
          
          // Select an ad based on the keywords
          const selectedAd = adServer.selectAd(keywordMatches);
          logger.log("[Ad Server] Selected ad: " + (selectedAd?.brand || "None"));
          
          // Generate a mock analysis based on the code
          let analysisText = "";
          
          if (code.includes("React") || code.includes("react") || code.includes("useState") || code.includes("useEffect")) {
            analysisText = `## React Code Analysis
  
  ### Strengths
  - Good component structure
  - Proper use of React hooks
  
  ### Areas for Improvement
  - Consider adding error boundary for the fetch operation
  - Add loading state management
  - Implement data caching using useMemo or React Query
  - Add proper TypeScript types for better type safety
  
  ### Performance Considerations
  - Implement memoization for expensive calculations
  - Use React.memo for components that render frequently
  - Consider code splitting for larger applications`;
          } else if (code.includes("python") || code.includes("def ") || code.includes("import ")) {
            analysisText = `## Python Code Analysis
  
  ### Strengths
  - Good function documentation
  - Proper error handling with try/except
  - Type hints are implemented correctly
  
  ### Areas for Improvement
  - Consider using a context manager (with statement) for the requests
  - Add more specific exception handling
  - Implement logging instead of print statements
  - Consider adding unit tests for the function
  
  ### Best Practices
  - Follow PEP 8 guidelines for consistent formatting
  - Use dataclasses or TypedDict for structured data
  - Consider async/await for network operations`;
          } else {
            analysisText = `## Code Analysis
  
  ### Strengths
  - Good function structure
  - Input validation present
  - Clean chaining of array methods
  
  ### Areas for Improvement
  - Add more comprehensive error handling
  - Consider adding JSDoc comments for better documentation
  - Implement unit tests to verify functionality
  - Use TypeScript for type safety
  
  ### Performance Considerations
  - For large arrays, consider optimizing the multiple iterations
  - Add memoization for repeated operations
  - Consider using Set for unique value filtering
  
  ### Best Practices
  - Follow consistent naming conventions
  - Add more descriptive variable names
  - Consider breaking down complex operations into named functions`;
