# Group Buy Helper - 拼团/砍价助手

Analyze group-buy and bargain campaigns, estimate success probability, and suggest participation strategies. Use when the user asks to 分析拼团、估算砍价成功率、判断是否值得参团、生成拉人分享文案 or assess group-buy outcomes.

## Usage Scenarios

### Scenario 1: Bargain Success Estimation
**User input:** "分析砍价活动，还差 50 元，还有 24 小时，我已经有 30 个朋友帮忙了"
**Expected output:** The skill calculates based on typical per-helper amounts (e.g., new users give higher amounts, existing users give lower amounts), estimates the number of additional helpers needed, and provides: success probability (high/medium/low), recommended actions (continue recruiting / invite new users / consider abandoning), and whether the expected effort is worth the discount.

### Scenario 2: Group-Buy Feasibility Check
**User input:** "拼团成功率，还差 2 人，只剩 3 小时了"
**Expected output:** The skill considers time remaining, number of people needed, and typical group-buy conversion behavior. Provide a probability estimate, recommend whether to continue waiting or pay full price, and offer share-worthy text to recruit the last members.

### Scenario 3: Share Copy Generation
**User input:** "生成分享文案，帮我在微信群拉人拼这个团"
**Expected output:** The skill generates 2-3 ready-to-copy share texts optimized for different social contexts (WeChat group, Moments, direct message). Each includes: what the product is, the discount being offered, a clear call to action, and a note about how many people are still needed. Text is persuasive but not spammy.
