# Templates — first-class

> 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: "默认查明天的头等舱航班"
Missing seat-class-name → Default: first (always for this skill)
```

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

### 3.2 No Results

```markdown
## ✈️ First Class Flights: {origin} → {destination}

No first class seats found for {date}.

**Tried:**
- ✅ Searched all flights with seat-class=first → 0 results
- ✅ Checked business class availability → {count} options

**Suggestions:**
1. Try a different date
2. Consider business class on this route
3. Check nearby airports
```

### 3.3 CLI Failed

```markdown
## ✈️ First Class Flights: {origin} → {destination}

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

**Next steps:**
- Check network: `flyai --version`
- Retry: `flyai search-flight --origin "{o}" --destination "{d}" --seat-class-name first --sort-type 2`

Real-time data requires a working flyai-cli.
