Implementation Reference

• src/tools/index.ts:1787-1794 (handler)

  The handler function for the 'meta_heterogeneity' tool. It takes input arguments, extracts the I² value, and returns an interpretation of heterogeneity level (low, moderate, high) along with implications for fixed vs random effects models in meta-analysis.

  function handleMetaHeterogeneity(args: Record<string, unknown>) {
    const iSquared = args.i_squared as number;
    return {
      i_squared: iSquared,
      interpretation: iSquared < 25 ? "Low heterogeneity" : iSquared < 75 ? "Moderate heterogeneity" : "High heterogeneity",
      implications: iSquared > 50 ? "Random effects model 권장, 이질성 원인 탐색" : "Fixed effect 가능"
    };
  }

• src/tools/index.ts:554-567 (schema)

  The tool registration object including name, description, and input schema definition for validating parameters like Q statistic, I², τ², and number of studies.

  {
    name: "meta_heterogeneity",
    description: "메타분석 이질성 해석 (Q, I², τ²)",
    inputSchema: {
      type: "object",
      properties: {
        q_stat: { type: "number", description: "Q 통계량" },
        i_squared: { type: "number", description: "I² 값" },
        tau_squared: { type: "number", description: "τ² 값" },
        k: { type: "number", description: "연구 수" },
      },
      required: ["i_squared", "k"],
    },
  },

• src/tools/index.ts:864-866 (registration)

  The switch case in handleToolCall that routes calls to the meta_heterogeneity tool to its handler function.

  case "meta_heterogeneity":
    return handleMetaHeterogeneity(args);
  case "publication_bias":
