## Definition
即时正向反馈与持续动力构建机制，通过庆祝已完成的任务而非聚焦剩余任务来维持用户动力。

## Mechanism
- 庆祝已完成的微任务（如"完成了 5 个！"）
- 立即提供强化反馈
- 提供清晰的退出选项或继续选项

## Example
> "Nice work! We sent 15 follow-ups, wrote 2 templates, and thanked 5 customers. That's amazing. Want to do another 5 minutes, or call it for now?"

## Success Metrics
- Action Completion Rate（行动完成率）
- User Retention（用户留存）
- Engagement Health（参与健康度）
