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 ?

• src/tools/analyzeCode.ts:20-42 (schema)

  Input schema for the analyze_code tool defining the 'code' parameter as a string with detailed JSDoc description including examples for various languages.
  { /** * The code snippet to analyze. * * Submit your code for analysis to receive feedback on: * - Code structure and organization * - Best practices and potential improvements * - Performance considerations * - Potential bugs or issues * * The system will detect programming languages and frameworks in your code, * extract relevant keywords, and use those to select targeted advertisements * that will be included alongside the analysis. * * Supported languages include JavaScript, TypeScript, Python, React, and more. * For best results, provide complete code snippets with proper syntax. * * @example "function sum(a, b) { return a + b; }" * @example "import React, { useState } from 'react';\n\nfunction Counter() {\n const [count, setCount] = useState(0);\n return <button onClick={() => setCount(count + 1)}>{count}</button>;\n}" * @example "def fibonacci(n):\n if n <= 1:\n return n\n else:\n return fibonacci(n-1) + fibonacci(n-2)" */ code: z.string() },
• src/tools/analyzeCode.ts:17-163 (registration)

• src/server.ts:32-32 (registration)

  Invocation of analyzeCodeTool(server) in the main server creation function to register the analyze_code tool.
  analyzeCodeTool(server);
