19```
20WeChat API credentials not found.
21 
22To obtain credentials:
231. Visit https://mp.weixin.qq.com
242. Go to: 开发 → 基本配置
253. Copy AppID and AppSecret
26 
27Where to save?
28A) Project-level: .baoyu-skills/.env (this project only)
29B) User-level: ~/.baoyu-skills/.env (all projects)
30```
31 
32After they choose a location, collect the values (prefer a user-input tool, fall back to a numbered prompt per the User Input Tools rule in SKILL.md) and append:
33 
34```
35WECHAT_APP_ID=<user_input>
36WECHAT_APP_SECRET=<user_input>
37```
