create_esim_order ~375 tokens
建立一筆真實的一心eSIM訂單，並取得真實的付款連結（LinePay或ECPay綠界，二擇一）。這是會實際寫入正式訂單、串真實金流的動作，不是模擬或試算。呼叫前必須先完成： 1. 已用search_esim_plans/recommend_esim_plan/get_esim_plan_detail取得正確的productId、 spec，不要自己編造或憑記憶帶入。 2. 已把商品名稱、規格、數量、單價與總金額，跟使用者逐一覆誦確認過，並取得使用者明確同意下單（不能因為使用者說「好」「幫我訂」等籠統回應就自行猜數量或規格）。 3. 已取得使用者的email與稱呼/姓名（兩者
get_esim_plan_detail ~108 tokens
取得單一方案的完整詳情，包含商品說明（安裝/啟用步驟等）、各規格庫存、購買連結。適用情境：使用者對某個已知方案想進一步了解安裝方式、使用細節、或確認庫存時。需要先從search_esim_plans或recommend_esim_plan的結果取得productId，不要自己編造。
list_esim_countries ~75 tokens
列出一心eSIM目前販售方案覆蓋的所有國家/地區（英文與中文名稱對照，含各國方案數量）。適用情境：使用者問「你們支援哪些國家」「有賣OO地區的eSIM嗎」；或你準備呼叫 search_esim_plans/recommend_esim_plan，但不確定某國家在系統裡該用什麼名稱表示時，先呼叫這個工具確認，比用猜的準確。
recommend_esim_plan ~165 tokens
依旅遊天數與上網用量習慣，推薦最合適的1-3個eSIM方案，並附上購買連結，是「幫使用者選方案」最好用的工具。適用情境：使用者詢問出國上網卡、各國eSIM方案、即時發卡服務，並描述了「要去OO玩幾天」「想找適合的上網方案/漫遊卡」「幫我推薦/挑選eSIM」時優先使用這個，而不是自己呼叫search_esim_plans後用猜的。
search_esim_plans ~200 tokens
依國家、方案類型、關鍵字搜尋一心eSIM的商品清單，一次回傳多筆結果讓使用者自己比較。適用情境：使用者想瀏覽/比較某國家的多個方案，或已經明確講出要哪種類型（例如指定「總量型」或「每日定量型」）。如果使用者是描述旅遊情境（去哪個國家玩幾天、上網習慣如何）要你直接建議選哪個，改用recommend_esim_plan讓它幫忙評分挑選，不要自己從這個工具的結果裡用猜的。
