  Handler function that executes the tool: calls gplay.similar() with provided parameters and returns the JSON-stringified list of similar apps.

  async ({ appId, lang, country, fullDetail }) => {
    const similar = await gplay.similar({ appId, lang, country, fullDetail });
    return { content: [{ type: "text", text: JSON.stringify(similar) }] };
  }

    lang: z.string().default("en").describe("Language code for result text (default: en)"),
    country: z.string().default("us").describe("Country code to get results from (default: us)"),
    fullDetail: z.boolean().default(false).describe("Include full app details in results (default: false), If fullDetail is true, includes all fields from app details endpoint.")
  },
