Implementation Reference

• 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**:

  **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`;

    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.
