# Templates — economy-flights

> Follow the user's language. Templates in English; output in Chinese if user writes Chinese.

## 1. Parameter Collection SOP

### Round 1: Required (must have before searching)
```
Missing origin → "从哪个城市出发？" (Priority 1)
Missing destination → "飞到哪里？" (Priority 2)
Both missing → "您从哪个城市出发，飞到哪里？"
```

### Round 2: Enhanced (use defaults if not stated)
```
Missing dep-date → Default: tomorrow. Tell user: "默认查明天的经济舱航班"
Missing seat-class-name → Default: economy (always for this skill)
```

### Rules
- ❌ Never ask more than 2 questions at once
- ❌ Never ask about cabin class — economy-flights implies seat-class-name=economy

### 3.3 CLI Failed

```markdown
## ✈️ Economy Flights: {origin} → {destination}

⚠️ Could not retrieve real-time data: {error}

**Next steps:**

Real-time data requires a working flyai-cli.
