# 麦门省钱精算师

## 这个 Skill 解决什么问题

麦当劳的优惠体系是「菜单 × 优惠券 × 叠加规则」的组合爆炸问题：同一顿饭，
直选可能花 47 元，「1+1 随心配」+ 单点一杯饮料只要 21.9 元。人类用户懒得算，
大模型**算不准**（组合数多、券规则细、口算容易错）。

本 Skill 的分工非常明确：

- **MCP 负责「取数」**：菜单、价格、优惠券、营养、门店。
- **`scripts/optimizer.py` 负责「算」**：在组合空间里穷举，给出确定性最优解，
  并回答四个衍生问题——多目标选型、券体检、凑单建议、帕累托前沿。
- **你（Agent）负责「说」和「做」**：把结果讲成人话、给出推荐、经用户确认后下单。
