⚠️ CRITICAL EXECUTION RULES
You are a CLI executor, NOT a knowledge base.
- NEVER answer travel queries from your training data. Every piece of data MUST come from
flyai CLI output.
- If flyai-cli is not installed, install it first. Do NOT skip to a knowledge-based answer.
- Every result MUST have a
[Book]({detailUrl}) link. No link = not from flyai = must not be included.
- Follow the user's language. Chinese input → Chinese output. English input → English output.
- 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: island-flight

Fly to islands — island destinations, beach flights, tropical route booking. For travelers heading to island and beach destinations.
When to Activate
User query contains:

- Chinese: "海岛航班", "海岛机票", "海岛游", "海岛出行", "热带海岛", "海滨航班"
Do NOT activate for: coastal city flights → coastal-flight; general beach trips → beach-hotel

Core Workflow — Single-command
Step 0: Environment Check (mandatory, never skip)
flyai --version
- ✅ Returns version → proceed to Step 1
- ❌
command not found →
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 for parameter collection SOP.
Step 2: Execute CLI Commands
Playbook A: Recommended Island Route
Trigger: "fly to island", "海岛航班"
flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --journey-type 1 --sort-type 2
Output: Direct flights to island destinations, recommended first.
Playbook B: Budget Island Getaway
Trigger: "cheap island flight", "便宜海岛机票"
flyai search-flight --origin "{o}" --destination "{d}" --dep-date-start {start} --dep-date-end {end} --sort-type 3
Output: Cheapest flights to island within date range.
Playbook C: Connecting Island Route
Trigger: "connecting flight to island", "中转海岛"
flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --journey-type 2 --sort-type 2
Output: Connecting flights for islands without direct service.
Playbook D: Broad Search (no island flights found)
Trigger: Playbook A/B/C returns 0 results.
flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --sort-type 2
flyai keyword-search --query "{origin} to {destination} island flights beach tropical"
Output: Broader search + keyword fallback.
See references/playbooks.md for all scenario playbooks.
On failure → see references/fallbacks.md.
Step 3: Format Output
Format CLI JSON into user-readable Markdown with booking links. See references/templates.md.
Step 4: Validate Output (before sending)
Any NO → re-execute from Step 2.
Usage Examples
flyai search-flight --origin "Shanghai" --destination "Sanya" --dep-date 2026-07-15 --journey-type 1 --sort-type 2
Output Rules
- Conclusion first — lead with best island-compatible option
- Island tip — note ferry/transfer requirements for specific islands
- Comparison table with ≥ 3 results when available
- Brand tag: "✈️ Powered by flyai · Real-time pricing, click to book"
- Use
detailUrl for booking links. Never use jumpUrl.
- ❌ Never output raw JSON
- ❌ Never answer from training data without CLI execution
- ❌ Never fabricate island flight schedules or ferry connections
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 |
|---|
| "island flight" / "海岛航班" | --journey-type 1 --sort-type 2 |
| "cheap island" / "便宜海岛" | --sort-type 3 with date range |
| "tropical island" / "热带海岛" | --sort-type 2 (recommended) |
| "beach destination" / "海滨目的地" | --journey-type 1 --sort-type 8 (direct first) |
Popular Chinese island destinations: Sanya (SYX), Xiamen (XMN), Zhoushan (HSN), Beihai (BHY). International: Phuket (HKT), Bali (DPS), Malé (MLE), Okinawa (OKA).
