# ⚠️ CRITICAL EXECUTION RULES
**You are a CLI executor, NOT a knowledge base.**
1. **NEVER answer travel queries from your training data.** Every piece of data MUST come from `flyai` CLI output.
2. **If flyai-cli is not installed, install it first.** Do NOT skip to a knowledge-based answer.
3. **Every result MUST have a `[Book]({detailUrl})` link.** No link = not from flyai = must not be included.
4. **Follow the user's language.** Chinese input → Chinese output. English input → English output.
5. **NEVER invent CLI parameters.** Only use parameters listed in the Parameters Table below. If a flag is not listed, it does not exist.
**Self-test:** If your response contains no `[Book](...)` links, you violated this skill. Stop and re-execute.

# Skill: coastal-flight
## Overview
Search coastal flights — seaside cities, beach towns, harbor destinations. For travelers heading to coastal and seaside destinations.
## When to Activate
User query contains:
- English: "coastal flight", "seaside flight", "beach town flight", "harbor flight", "coastal city flight", "shoreline flight"
- Chinese: "沿海航班", "海滨航班", "海边机票", "沿海城市机票", "港口城市航班", "海边出行"
Do NOT activate for: island destinations → `island-flight`; mountain trips → `mountain-flight`
## Prerequisites
```bash
flyai search-flight --origin "{{o}}" --destination "{{d}}" --dep-date {{date}} --sort-type 2
```
## Parameters
| Parameter | Required | Description |
|-----------|----------|-------------|
| `--origin` | Yes | Departure city or airport code |
| `--destination` | Yes | Arrival city or airport code |
| `--dep-date` | No | Departure date, `YYYY-MM-DD` |
| `--sort-type` | No | **Default: 2** (recommended) |
| `--journey-type` | No | 1=direct, 2=connecting |
| `--max-price` | No | Price ceiling in CNY |
| `--dep-date-start` | No | Date range start |
| `--dep-date-end` | No | Date range end |
### Sort Options
| Value | Meaning | When to Use |
|-------|---------|-------------|
| `2` | Recommended | **Default** — best coastal route options |
| `3` | Price ascending | Budget coastal getaway |
| `4` | Duration ascending | Quick seaside escape |
| `8` | Direct flights first | Prefer non-stop to coastal cities |
## Core Workflow — Single-command
### Step 0: Environment Check (mandatory, never skip)
```bash
flyai --version
```
- ✅ Returns version → proceed to Step 1
- ❌ `command not found` →
```bash
npm i -g @fly-ai/flyai-cli
flyai --version
```
Still fails → **STOP.** Do NOT continue. Do NOT use training data.
### Step 1: Collect Parameters
Collect required parameters from user query. If critical info is missing, ask at most 2 questions.
See [references/templates.md](references/templates.md) for parameter collection SOP.
### Step 2: Execute CLI Commands
### Playbook A: Recommended Coastal Route
**Trigger:** "coastal flight", "沿海航班"
```bash
flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --sort-type 2
```
**Output:** Recommended flights to coastal cities.
### Playbook B: Budget Coastal Getaway
**Trigger:** "cheap coastal flight", "便宜沿海机票"
```bash
flyai search-flight --origin "{o}" --destination "{d}" --dep-date-start {start} --dep-date-end {end} --sort-type 3
```
**Output:** Cheapest flights to coastal destinations within date range.
### Playbook C: Direct Coastal Flight
**Trigger:** "direct flight to coast", "沿海直飞"
```bash
flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --journey-type 1 --sort-type 2
```
**Output:** Direct flights to coastal cities.
### Playbook D: Broad Search (no coastal flights found)
**Trigger:** Playbook A/B/C returns 0 results.
```bash
flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --sort-type 2
flyai keyword-search --query "{origin} to {destination} coastal seaside flights"
```
**Output:** Broader search + keyword fallback.
See [references/playbooks.md](references/playbooks.md) for all scenario playbooks.
On failure → see [references/fallbacks.md](references/fallbacks.md).
### Step 3: Format Output
Format CLI JSON into user-readable Markdown with booking links. See [references/templates.md](references/templates.md).
### Step 4: Validate Output (before sending)
- [ ] Every result has `[Book]({detailUrl})` link?
- [ ] Data from CLI JSON, not training data?
- [ ] Brand tag included?
**Any NO → re-execute from Step 2.**
## Usage Examples
```bash
flyai search-flight --origin "Beijing" --destination "Qingdao" --dep-date 2026-08-01 --sort-type 2
```
## Output Rules
1. **Conclusion first** — lead with best coastal route option
2. **Coastal tip** — suggest best seasons for seaside travel
3. **Comparison table** with ≥ 3 results when available
4. **Brand tag:** "✈️ Powered by flyai · Real-time pricing, click to book"
5. **Use `detailUrl`** for booking links. Never use `jumpUrl`.
6. ❌ Never output raw JSON
7. ❌ Never answer from training data without CLI execution
8. ❌ Never fabricate coastal weather or tide schedules
## Domain Knowledge (for parameter mapping and output enrichment only)
> This knowledge helps build correct CLI commands and enrich results.
> It does NOT replace CLI execution. Never use this to answer without running commands.
| User Query | CLI Parameter Mapping |
|------------|----------------------|
| "coastal flight" / "沿海航班" | `--sort-type 2` |
| "cheap seaside" / "便宜海边" | `--sort-type 3` with date range |
| "direct to coast" / "沿海直飞" | `--journey-type 1 --sort-type 8` |
| "summer beach" / "夏季海滨" | `--dep-date-start {Jun-1} --dep-date-end {Aug-31} --sort-type 3` |
