  Registration of the wp_performance_benchmark tool, including schema (parameters) and handler binding in PerformanceTools.getTools() method.

    parameters: [
      {
        name: "site",

    handler: this.getBenchmarkComparison.bind(this),
  },

• src/tools/performance/PerformanceTools.ts:467-537 (handler)

  Handler function that executes the tool: collects benchmarks from PerformanceAnalytics, filters by category, generates recommendations, formats results using helpers, and returns structured comparison data.

  private async getBenchmarkComparison(_client: WordPressClient, params: Record<string, unknown>): Promise<unknown> {
    return toolWrapper(async () => {
      const {
        site,
        category = "all",
        includeRecommendations = true,
      } = params as {
        site?: string;
        category?: string;
        includeRecommendations?: boolean;
      };
  
      // Get benchmark comparisons
      const benchmarks = this.analytics.benchmarkPerformance() as BenchmarkComparison[];
  
      // Filter by category if specified
      let filteredBenchmarks = benchmarks;
      if (category !== "all") {
        const categoryMap: Record<string, string> = {
          response_time: "Response Time",
          cache_performance: "Cache Hit Rate",
          error_rate: "Error Rate",
          system_resources: "Memory Usage",
        };
        const targetCategory = categoryMap[category as string];
        if (targetCategory) {
          filteredBenchmarks = benchmarks.filter((b) => b.category === targetCategory);
        }
      }
  
      // Get recommendations if requested
      let recommendations = null;
      if (includeRecommendations) {
        const insights = this.analytics.generateInsights();
        recommendations = insights
          .filter((insight) => insight.category === "optimization")
          .map((insight) => ({
            title: insight.title,
            description: insight.description,
            priority: insight.priority,
            estimatedImprovement: insight.estimatedImprovement,
            implementationEffort: insight.implementationEffort,
          }));
      }
  
      return {
        success: true,
        data: {
          benchmarks: filteredBenchmarks.map((benchmark) => ({
            ...benchmark,
            status: formatBenchmarkStatus(benchmark.status),
            improvement:
              benchmark.improvement > 0
                ? {
                    needed: benchmark.improvement,
                    description: getBenchmarkImprovementDescription(benchmark),
                  }
                : null,
          })),
          overallRanking: calculateOverallRanking(benchmarks),
          recommendations: recommendations || [],
          metadata: {
            timestamp: new Date().toISOString(),
            category,
            site: site || "all",
            benchmarkVersion: "2024-industry-standards",
          },
        },
      };
    });
  }

• src/tools/performance/PerformanceHelpers.ts:175-184 (helper)

  Helper function to format benchmark status with emojis, used in the handler for output formatting.

  export function formatBenchmarkStatus(status: string): string {
    const statusMap: Record<string, string> = {
      excellent: "🟢 Excellent",
      good: "🟡 Good",
      average: "🟠 Average",
      below_average: "🔴 Below Average",
      poor: "⚫ Poor",
    };
    return statusMap[status] || status;
  }

• src/tools/performance/PerformanceHelpers.ts:189-197 (helper)

  Helper to generate human-readable improvement descriptions for benchmarks, used conditionally in the handler.

  export function getBenchmarkImprovementDescription(benchmark: BenchmarkComparison): string {
    const improvements: Record<string, string> = {
      "Response Time": `Reduce by ${benchmark.improvement.toFixed(0)}ms`,
      "Cache Hit Rate": `Increase by ${benchmark.improvement.toFixed(1)}%`,
      "Error Rate": `Reduce by ${benchmark.improvement.toFixed(2)}%`,
      "Memory Usage": `Reduce by ${benchmark.improvement.toFixed(0)}%`,
    };
    return improvements[benchmark.category] || `Improve by ${benchmark.improvement}`;
  }

• src/tools/performance/PerformanceHelpers.ts:202-215 (helper)

  Helper to compute overall performance ranking percentile and status from benchmark results, used in handler summary.

  export function calculateOverallRanking(benchmarks: BenchmarkComparison[]): { percentile: number; status: string } {
    const statuses = benchmarks.map((b) => b.status);
    const excellentCount = statuses.filter((s) => s === "excellent").length;
    const goodCount = statuses.filter((s) => s === "good").length;
  
    const percentile = ((excellentCount + goodCount * 0.8) / statuses.length) * 100;
  
    let status = "Needs Improvement";
    if (percentile >= 90) status = "Top Performer";
    else if (percentile >= 75) status = "Above Average";
    else if (percentile >= 50) status = "Average";
  
    return { percentile: Math.round(percentile), status };
  }
