    if (!cfg.newsApiKey) throw new Error("NEWS_API_KEY is not configured");
    const query = String(args.query || "");
    if (!query) throw new Error("query is required");
    const from_date = args.from_date ? String(args.from_date) : undefined;
    const to_date = args.to_date ? String(args.to_date) : undefined;
    return client.search(query, from_date, to_date);
  },

• src/apis/news/newsapi.ts:54-62 (schema)

      from_date: { type: "string" },
      to_date: { type: "string" },
    },

  },
