kenyanghuiandClaude 1d04e1bf00 Add wechat-ops skill
macOS GUI automation via a screenshot → vision-locate → act → verify loop.
Coordinates are never hard-coded; every step is located live and confirmed
by re-screenshot.

"""
视觉自动化助手 — 用「截图 + 视觉识别」代替固定坐标定位。
设计原则:
1. 截图统一缩放到逻辑分辨率,图上坐标 == 点击坐标(免换算)
2. 每个原子动作可独立调用,由视觉判断决定下一步
3. 点完可再截图验证,形成闭环
用法:
python3 vision.py shot [名字] 截图到 /tmp/wechat_ops/<名字>.png
python3 vision.py click X Y 在逻辑坐标 (X,Y) 单击
python3 vision.py dclick X Y 双击
python3 vision.py move X Y 移动鼠标
python3 vision.py activate 微信 激活窗口
python3 vision.py type "文本" 输入文本(走剪贴板,支持中文)
python3 vision.py key enter 按键,如 enter / esc / cmd+v
python3 vision.py scroll N [X Y] 滚动(正数向上),可指定鼠标落点
python3 vision.py pos 打印当前鼠标位置与屏幕尺寸
