Promotion Engine

Overview

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 Types

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

Calculation Steps

Always show calculation steps. Customers distrust "magic numbers."

Step 1: Identify applicable promotions

For each item in the cart/query:

  1. Check promotions[] for active promos (not expired)
  2. Filter by applicable_to scope (does this product qualify?)
  3. Check excluded list (is this product excluded?)
  4. Check membership tier for additional discounts

Step 2: Apply promotion rules

Use scripts/calculate_promotion.py for accurate computation.

Promotion types:

Type Rule format Example
threshold 满X减Y 满300减50
discount X折 or X% off 8折, 20% off
bundle 买X件享Y价 买2件第2件半价
gift 满X赠品 满200赠小样
member_price 会员专属价 VIP价¥199

Step 3: Handle stacking

Check stackable field on each promotion.

  • stackable: true → can combine with others
  • stackable: false → use highest-value single promo
  • When in doubt: use the rule that benefits the customer more

Step 4: Present result

Show original price → applicable promos → final price → total savings.

Answer Format

Single item query

这款连衣裙 原价：¥399
✨ 夏日大促：满300减50
会员折扣：9折（VIP专享）

最终价格：¥309（节省¥90）

Cart calculation

您的购物清单：
  白色连衣裙 ×1   ¥399
  条纹衬衫   ×1   ¥259
  小计：¥658

✨ 满300减50 → -¥50
✨ 满600再减80 → -¥80（两件合计超过600！）

最终合计：¥528（节省¥130 🎉）

No active promotions

目前[产品/全场]暂无特别优惠活动。
当前售价：¥[price]

Edge Cases

Conflicting promos: Always apply the rule that benefits the customer most. State which was applied.

Expired promo mentioned by customer: "这个活动已于[date]结束了，目前[有/没有]新的优惠。"

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。"
