麦门省钱体检

什么时候用

  • 用户给出「我常点 X + Y + Z」,想知道有没有更省的买法
  • 用户问「满 60 减 12,我要不要凑」
  • 用户想复盘历史订单「有没有买贵」
  • 用户问「这两个套餐哪个更值」

什么时候不用

  • 只想下单 → 直接用点餐流程
  • 问营养/热量 → 用 list-nutrition-foods
  • 问活动/派对 → 用 query-party-*
  • 要求「保证最低价」→ 只能给当前接口口径下的最优,不能承诺

工作流

  1. 取数:now-time-info → query-nearby-stores → query-meals → query-meal-detail
  2. 取优惠:query-store-coupons + available-coupons(有可领的,提示「先领再算」)
  3. 枚举:本地生成候选买法(单点 / 套餐组合 / 套餐+补单点)
  4. 判价:每个候选调一次 calculate-price,取官方应付金额
  5. 排序归因:算差额,指出省在「换套餐 / 用券 / 满减」哪一项
  6. 凑单体检:对每个未达门槛的满减,算「加购多少钱 → 省多少 → 净赚还是净亏」
  7. 输出:见下方契约

输出契约

一、你点的是        商品 × 数量,单点合计
二、能怎么买        表格:买法 / 实付 / 比原样省 / 备注(多得什么)
三、最优            一句话:哪个买法、实付多少、省多少
四、账单拆解        逐项列出套餐、券、满减各贡献多少
五、凑单体检        每个门槛:差多少、要加购多少、净赚/净亏多少

硬规则

  • 每个金额必须来自 calculate-price,不得自行估算
  • 满减与券默认二选一;数据标明可叠加才叠加
  • 「多得」的商品必须显式标出,不能假装是同一样东西
  • 结尾必须给一个可执行动作(领券 / 换套餐 / 别凑)

示例

用户:帮我体检一下:巨无霸 + 中薯条 + 中可乐

按单点算:45 元

| 买法 | 实付 | 比原样省 |
|---|---:|---:|
| 巨无霸套餐 + 巨无霸立减 5 元 | 34.5 | 10.5 |
| 单点 + 满 40 减 8 | 37 | 8 |
| 单点 | 39 | 6 |

最优:巨无霸套餐 + 巨无霸立减 5 元,实付 34.5 元,省 10.5 元。

凑单体检:满 45 减 6 还差 10.5,最少要加购 14 元才够,
只减 6 元 → 净亏 8 元,不建议凑。
