• src/tools/ai-enhanced-tools.ts:462-467 (registration)

  The tool is instantiated and added to the aiEnhancedTools export array, serving as the registry for AI-enhanced tools.

  export const aiEnhancedTools = [
    new NaturalQueryBuilderTool(),
    new SmartDataAnalysisTool(),
    new QueryPerformanceOptimizerTool(),
    new BusinessProcessInsightsTool(),
  ];
