⚠️ 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 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: border-flight

Overview

Cross-border flights — international departures, visa-required routes, overseas travel. For travelers flying internationally across borders.

When to Activate

User query contains:

Do NOT activate for: domestic flights → economy-flights; connecting flights → connecting

Prerequisites

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 international options | | 3 | Price ascending | Budget international travel | | 4 | Duration ascending | Fastest international route | | 8 | Direct flights first | Prefer non-stop international |

Core Workflow — Single-command

Step 0: Environment Check (mandatory, never skip)

flyai --version

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 International Route

Trigger: "international flight", "国际航班"

flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --sort-type 2

Output: Recommended international flights.

Playbook B: Budget International Travel

Trigger: "cheap international flight", "便宜国际机票"

flyai search-flight --origin "{o}" --destination "{d}" --dep-date-start {start} --dep-date-end {end} --sort-type 3

Output: Cheapest international flights within date range.

Playbook C: Direct International Flight

Trigger: "direct international flight", "国际直飞"

flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --journey-type 1 --sort-type 2

Output: Direct international flights.

Playbook D: Broad Search (no international 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} international flights"

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 "Tokyo" --dep-date 2026-06-01 --sort-type 2

Output Rules

1. Conclusion first — lead with best international option 2. Visa reminder — note visa requirements for the destination country 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 visa policies or entry requirements

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 | |------------|----------------------| | "international flight" / "国际航班" | --sort-type 2 | | "cheap overseas" / "便宜出国" | --sort-type 3 with date range | | "direct international" / "国际直飞" | --journey-type 1 --sort-type 8 | | "outbound flight" / "出境航班" | --sort-type 2 |

Major Chinese international hubs: PEK, PVG, CAN, SZX, CTU. CLI does not have a border/customs filter — all results are regular flights.
