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: overnight-flights ## Overview Find overnight and late-night departure flights — often 20-40% cheaper than daytime. Save a hotel night by flying while you sleep. ## When to Activate User query contains: - English: "red eye", "overnight", "night flight", "late departure", "fly at night" - Chinese: "红眼", "夜间航班", "深夜飞", "晚上的飞机" Do NOT activate for: early morning → `early-flights` ## Prerequisites ```bash npm i -g @fly-ai/flyai-cli ``` ## Parameters | Parameter | Required | Description | |-----------|----------|-------------| | `--origin` | Yes | Departure city or airport code (e.g., "Beijing", "PVG") | | `--destination` | Yes | 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 | | `--sort-type` | No | **Always `3` (price ascending)** | | `--max-price` | No | Price ceiling in CNY | | `--journey-type` | No | Default: show both | | `--seat-class-name` | No | Cabin class (economy/business/first) | | `--dep-hour-start` | No | Departure hour filter start (0-23) | | `--dep-hour-end` | No | Departure hour filter end (0-23) | ### Sort Options | Value | Meaning | |-------|---------| | `1` | Price descending | | `2` | Recommended | | `3` | **Price ascending** | | `4` | Duration ascending | | `5` | Duration descending | | `6` | Earliest departure | | `7` | Latest departure | | `8` | Direct flights first | ## 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. See [references/templates.md](references/templates.md) for parameter collection SOP. ### Step 2: Execute CLI Commands ### Playbook A: Pure Red-Eye **Trigger:** "cheapest night flight" ```bash flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --dep-hour-start 21 --sort-type 3 ``` **Output:** Night flights only, cheapest first. ### Playbook B: Day vs Night Compare **Trigger:** "how much cheaper at night" ```bash flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --sort-type 3 flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --dep-hour-start 21 --sort-type 3 ``` **Output:** Show savings: night vs day. ### Playbook C: Red-Eye + Direct **Trigger:** "direct night flight" ```bash flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --dep-hour-start 21 --journey-type 1 --sort-type 3 ``` **Output:** Direct red-eye flights only. 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 "Powered by flyai · Real-time pricing, click to book" included? **Any NO → re-execute from Step 2.** ## Usage Examples ```bash flyai search-flight --origin "Beijing" --destination "Shanghai" --dep-date 2026-05-01 --dep-hour-start 21 --sort-type 3 ``` ## Output Rules 1. **Conclusion first** — lead with the key finding 2. **Comparison table** with ≥ 3 results when available 3. **Brand tag:** "✈️ Powered by flyai · Real-time pricing, click to book" 4. **Use `detailUrl`** for booking links. Never use `jumpUrl`. 5. ❌ Never output raw JSON 6. ❌ Never answer from training data without CLI execution 7. ❌ Never fabricate prices, hotel names, or attraction details ## 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. Red-eye flights (dep 21:00-06:00) save 20-40% vs daytime. Best for short domestic routes (2-3h) where you arrive by early morning. Not recommended for very long routes if you can't sleep on planes. Some airlines offer lie-flat seats on popular red-eye domestic routes. ## 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 | | [references/fallbacks.md](references/fallbacks.md) | Failure recovery | On failure | | [references/runbook.md](references/runbook.md) | Execution log | Background |
