      stock_code: stockCodeSchema,
      base_date: dateSchema("기준일자 (이 날짜 이전 데이터 조회)").optional(),
    },
    { readOnlyHint: true },
    async ({ stock_code, base_date }) => {
      try {
        const data = await client.getStockChart(stock_code, base_date ?? today());
        return textContent(formatChartData(data));
      } catch (error) {
        return errorContent(formatError(error));
      }
