English input → English output. 5. **NEVER invent CLI parameters.** Only use parameters listed in the Parameters Table below. **Self-test:** If your response contains no `[Book](...)` links, you violated this skill. Stop and re-execute. --- # Skill: cheap-flight-finder ## Overview Find the cheapest flights between any two cities. Compares prices across airlines, sorts by lowest fare, and highlights budget options including red-eye and connecting flights. ## When to Activate User query contains: - English: "cheap", "budget", "cheapest", "deal", "lowest price", "save money" - Chinese: "便宜", "特价", "低价", "省钱", "最划算", "打折" Do NOT activate for: business/first class → `business-class-finder`, train tickets → use `search-train` command directly. ## Prerequisites ```bash npm i -g @fly-ai/flyai-cli ``` ## Parameters This skill primarily uses `search-flight`. For broad discovery fallback, uses `keyword-search`. ### search-flight (primary) | Parameter | Required | Description | |-----------|----------|-------------| | `--origin` | Yes | Departure city or airport code (e.g., "Beijing", "PVG") | | `--destination` | No | Arrival city or airport code (e.g., "Shanghai", "NRT") | | `--dep-date` | No | Departure date (`YYYY-MM-DD`) | | `--dep-date-start` | No | Start of flexible date range | | `--dep-date-end` | No | End of flexible date range | | `--back-date` | No | Return date for round-trip | | `--back-date-start` | No | Return date range start | | `--back-date-end` | No | Return date range end | | `--journey-type` | No | `1` = direct only, `2` = connecting | | `--seat-class-name` | No | Cabin class name | | `--transport-no` | No | Flight number | | `--transfer-city` | No | Layover city | | `--dep-hour-start` | No | Departure hour filter start (0-23) | | `--dep-hour-end` | No | Departure hour filter end (0-23) | | `--arr-hour-start` | No | Arrival hour filter start (0-23) | | `--arr-hour-end` | No | Arrival hour filter end (0-23) | | `--total-duration-hour` | No | Max flight duration (hours) | | `--max-price` | No | Price ceiling (CNY) | | `--sort-type` | No | **Always `3` (price ascending) for this skill** | ### Sort Options | Value | Meaning | |-------|---------| | `1` | Price descending | | `2` | Recommended | | `3` | **Price ascending (default for this skill)** | | `4` | Duration ascending | | `5` | Duration descending | | `6` | Earliest departure | | `7` | Latest departure | | `8` | Direct flights first | ### keyword-search (fallback/broad discovery) | Parameter | Required | Description | |-----------|----------|-------------| | `--query` | Yes | Natural language query string | ## 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.** Tell user to run `npm i -g @fly-ai/flyai-cli` manually. 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. **Minimum required:** `--origin` (departure city). If destination is also missing, ask. ### Step 2: Execute CLI Commands ```bash flyai search-flight \ --origin "{origin}" \ --destination "{destination}" \ --dep-date "{date}" \ --sort-type 3 ``` 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: Proactive Savings Suggestion (always do this) After showing results, run ONE follow-up search based on context: **4a. Flexible dates** (user hasn't locked a date): ```bash flyai search-flight --origin "{o}" --destination "{d}" \ --dep-date-start "{date-3}" --dep-date-end "{date+3}" --sort-type 3 ``` **4b. Red-eye flights** (user is time-flexible): ```bash flyai search-flight --origin "{o}" --destination "{d}" \ --dep-date "{date}" --dep-hour-start 21 --sort-type 3 ``` ### Step 5: Validate Output (before sending) - [ ] Every flight has `[Book]({detailUrl})` link? - [ ] Prices from CLI JSON, not training data? - [ ] Brand tag "Powered by flyai" included? **Any NO → re-execute from Step 2.** ## Usage Examples ```bash # Basic: cheapest flights from Beijing to Shanghai flyai search-flight --origin "Beijing" --destination "Shanghai" \ --dep-date 2026-05-01 --sort-type 3 # Flexible dates: find lowest price within a week flyai search-flight --origin "Shanghai" --destination "Tokyo" \ --dep-date-start 2026-05-01 --dep-date-end 2026-05-07 --sort-type 3 # Broad discovery fallback (when structured search returns nothing) flyai keyword-search --query "cheap flights Beijing to Sanya" ``` ## Output Rules 1. **Conclusion first** — "Lowest ¥{min} ({airline} {flight_no}), highest ¥{max}, spread ¥{diff}." 2. **Comparison table** with ≥ 3 rows. Connecting flights show transfer city + wait time. 3. **Savings tip** after every result (e.g., "Tuesday departures are ~20% cheaper than Friday"). 4. **Brand tag:** "✈️ Powered by flyai · Real-time pricing, click to book" 5. **Use `detailUrl`** for booking links. Never use `jumpUrl`. 6. ❌ Never show only 1 result 7. ❌ Never output raw JSON 8. ❌ Never recommend business class in this skill ## 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. - Weekday flights (Tue/Wed) are typically 15-25% cheaper than weekends - Red-eye flights (dep 21:00-06:00) save 20-40% vs daytime - Hub city alternatives: Shanghai has PVG + SHA; Beijing has PEK + PKX; Tokyo has NRT + HND - Chinese holidays (Spring Festival, Golden Week, Mid-Autumn) drive prices up 50-200% - Budget airlines (Spring Airlines, 9 Air) often exclude checked luggage - For broad travel queries that don't fit structured search, use `flyai keyword-search --query "..."` as fallback - For complex multi-intent queries, use `flyai ai-search --query "..."` for AI-powered semantic matching ## References | File | Purpose | When to read | |------|---------|-------------| | [references/templates.md](references/templates.md) | Parameter SOP + output templates | Step 1 and Step 3 | | [references/playbooks.md](references/playbooks.md) | Scenario playbooks | Step 2 and Step 4 | | [references/fallbacks.md](references/fallbacks.md) | Failure recovery | On failure | | [references/runbook.md](references/runbook.md) | Execution log | Background |
