This skill looks up active promotions and calculates final prices.
It always shows its work (calculation steps) so customers trust the answer.
Depends on: promotions[] in knowledge base + membership{} config.
| Query | Example | Action |
|---|---|---|
| ------- | --------- | -------- |
| "What promotions are active?" | "现在有什么活动？" | List all active promos |
| "How much will I pay?" | "买两件怎么算？" | Calculate total |
| "Is this on sale?" | "这款打折吗？" | Check promo applicability |
| "How do I get the best deal?" | "怎么买最划算？" | Optimize purchase strategy |
| "Can I stack promos?" | "会员折扣和满减可以一起用吗？" | Check stackability |
Always show calculation steps. Customers distrust "magic numbers."
For each item in the cart/query:
promotions[] for active promos (not expired)applicable_to scope (does this product qualify?)excluded list (is this product excluded?)Use scripts/calculate_promotion.py for accurate computation.
Promotion types:
| Type | Rule format | Example |

Promo not in KB but customer claims it exists: "我目前没有查到这个活动的信息，建议向店员确认一下，以免信息有误。"
Membership tier unknown: "您的会员等级我暂时查不到，建议核实后，会员专属折扣会自动应用。"
