Implementation Reference
- index.js:185-229 (handler)The execution handler for the 'gemini_analyze_codebase' tool. It extracts parameters, constructs a specialized prompt based on focus area, calls Gemini 2.5 Flash model to analyze the codebase, and returns the analysis as text content.if (name === "gemini_analyze_codebase") { const { codebase, focus = "general" } = args; const focusPrompts = { architecture: "Analyze the overall architecture, design patterns, and structural issues. Suggest improvements.", duplications: "Find duplicated code, similar patterns, and opportunities for refactoring. Be specific.", security: "Identify security vulnerabilities, unsafe practices, and potential exploits.", performance: "Find performance bottlenecks, inefficient algorithms, and optimization opportunities.", general: "Provide a comprehensive analysis covering architecture, code quality, potential issues, and improvements.", }; const model = genAI.getGenerativeModel({ model: "gemini-2.5-flash" }); const prompt = `You are an expert code reviewer. Analyze this codebase with focus on: ${focus} ${focusPrompts[focus]} Codebase: \`\`\` ${codebase} \`\`\` Provide: 1. Key findings 2. Specific issues with file/line references 3. Actionable recommendations 4. Priority ranking (High/Medium/Low)`; const result = await model.generateContent(prompt); const response = await result.response; return { content: [ { type: "text", text: `[Gemini Codebase Analysis - ${focus}]\n\n${response.text()}`, }, ], }; }
