### 基础用法
- `.points` - 查看个人积分
- `.checkin` - 每日签到
- `.points leaderboard` - 积分排行榜
- `.points records` - 积分记录

### 积分获取方式
- **每日签到**：固定 10 积分
- **运势占卜**：随机 1-20 积分
- **游戏奖励**：根据游戏表现获得

### 示例
```
.points
.checkin
.points leaderboard
.points records
```

### 说明
- 每日签到只能进行一次
- 运势积分每次查看都有机会获得
- 积分记录保留最近 20 条
