• src/tools/stacks_blockchain/performance/sip012_cost_analysis.ts:227-321 (handler)

  The main execution handler for the 'generate_optimization_recommendations' tool. It takes contract pattern and issues, calls generatePatternOptimizations, and formats a comprehensive Markdown report with recommendations, roadmap, and SIP-012 specific advice.
  export const generateOptimizationRecommendationsTool: Tool<undefined, typeof OptimizationRecommendationScheme> = { name: "generate_optimization_recommendations", description: "Generate specific optimization recommendations for Clarity contracts based on SIP-012 improvements and best practices.", parameters: OptimizationRecommendationScheme, execute: async (args, context) => { try { await recordTelemetry({ action: "generate_optimization_recommendations" }, context); const recommendations = generatePatternOptimizations(args.contractPattern, args.currentIssues); return `# SIP-012 Optimization Recommendations ## Contract Pattern: ${args.contractPattern.toUpperCase()} ${args.targetThroughput ? `**Target Performance**: ${args.targetThroughput}` : ''} ## Current Issues Analysis ${args.currentIssues.map(issue => `- ${issue}`).join('\n')} ## Optimization Strategy ${recommendations.map((rec: any, index: number) => ` ### ${index + 1}. ${rec.title} **Priority**: ${rec.priority.toUpperCase()} **Expected Impact**: ${rec.impact} **Implementation Effort**: ${rec.effort} **Problem**: ${rec.problem} **Solution**: ${rec.solution} **Implementation**: \`\`\`clarity ${rec.code} \`\`\` **Benefits**: ${rec.benefits.map((b: string) => `- ${b}`).join('\n')} **SIP-012 Advantages**: ${rec.sip012Benefits} `).join('\n')} ## Implementation Roadmap ### Phase 1: Critical Optimizations (Week 1-2) ${recommendations.filter((r: any) => r.priority === 'high').map((r: any) => `- ${r.title}: ${r.impact}`).join('\n')} ### Phase 2: Performance Improvements (Week 3-4) ${recommendations.filter((r: any) => r.priority === 'medium').map((r: any) => `- ${r.title}: ${r.impact}`).join('\n')} ### Phase 3: Advanced Optimizations (Week 5-6) ${recommendations.filter((r: any) => r.priority === 'low').map((r: any) => `- ${r.title}: ${r.impact}`).join('\n')} ## SIP-012 Specific Optimizations ### Database Operations - **Leverage 2x Capacity**: Use increased read/write limits for complex operations - **Batch Processing**: Group operations to minimize overhead - **Efficient Indexing**: Optimize map key structures ### Storage Efficiency - **Dynamic Lists**: Take advantage of actual-size pricing - **Data Packing**: Combine related data into tuples - **Lazy Loading**: Defer expensive computations ### Performance Monitoring \`\`\`clarity ;; Add performance monitoring to your contracts (define-read-only (get-operation-cost) { estimated-runtime: u50000, read-operations: u2, write-operations: u1 } ) \`\`\` ## Testing Strategy 1. **Clarinet Performance Tests**: Measure actual costs 2. **Load Testing**: Test with maximum data sizes 3. **Benchmark Comparisons**: Before/after optimization 4. **Production Monitoring**: Track real-world performance ## Success Metrics - [ ] Runtime costs reduced by ${recommendations.filter(r => r.priority === 'high').length * 25}% - [ ] Database operations optimized for SIP-012 limits - [ ] Storage costs minimized with dynamic sizing - [ ] Transaction throughput improved - [ ] User experience enhanced with faster confirmations`; } catch (error) { return `❌ Failed to generate optimization recommendations: ${error}`; } }, };
• src/tools/stacks_blockchain/performance/sip012_cost_analysis.ts:25-32 (schema)

  Zod schema defining the input parameters for the tool: contractPattern (enum), currentIssues (array of strings), and optional targetThroughput.
  const OptimizationRecommendationScheme = z.object({ contractPattern: z.enum([ "token-contract", "nft-collection", "defi-pool", "dao-governance", "marketplace", "staking-pool", "generic" ]).describe("Type of contract pattern"), currentIssues: z.array(z.string()).describe("Current performance issues identified"), targetThroughput: z.string().optional().describe("Target performance goals"), });
• src/tools/index.ts:69-69 (registration)

  Registration of the tool in the FastMCP server within the registerTools function.
  server.addTool(generateOptimizationRecommendationsTool);
• src/tools/stacks_blockchain/performance/sip012_cost_analysis.ts:528-599 (helper)

  Core helper function that provides pattern-specific optimization recommendations (e.g., for token-contract, nft-collection) used in the tool's execute function.
