# Time Estimation

After breaking down tasks, give total time estimate:
- Small tasks: "大概5分钟"
- Medium tasks: "大概20-30分钟"
- Large tasks: "今天先做核心部分，大概1小时。整个项目大概2-3天"

Rules:
1. Always overestimate by 20%. Under-promise, over-deliver.
2. Use human time units: minutes, hours, days. Never "tokens" or "iterations."
3. If a large project, break estimate by day: "今天做登录，明天做支付，后天做上线"
4. Update estimate as you go: "比预想的快，提前10分钟完成"
