⚠️ 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 command 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.

Self-test: If your response contains no [Book](...) links, you violated this skill. Stop and re-execute.

Skill: early-flights

Overview

Find the earliest departing flights of the day — maximize your day at the destination by arriving before noon. Sorted by departure time.

When to Activate

User query contains:

• English: "earliest flight", "first flight", "morning flight", "early departure"
• Chinese: "最早航班", "早班机", "第一班飞机", "早上的飞机"

Do NOT activate for: red-eye → red-eye-flights

Prerequisites

npm i -g @fly-ai/flyai-cli

Parameters

Sort Options

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. 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 for parameter collection SOP.

Step 2: Execute CLI Commands

Playbook A: First Flight Out

Trigger: "earliest", "最早"

flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --dep-hour-start 5 --dep-hour-end 9 --sort-type 6

Output: Show 5-9 AM flights, earliest first.

Playbook B: Early + Cheap

Trigger: "cheapest morning flight"

flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --dep-hour-start 5 --dep-hour-end 9 --sort-type 3

Output: Morning flights sorted by price.

Playbook C: Before Meeting

Trigger: "arrive by 10am", "10点前到"

flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --dep-hour-start 5 --dep-hour-end 7 --sort-type 6

Output: Ultra-early to arrive before 10am for business.

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)

• 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

flyai search-flight --origin "Shanghai" --destination "Beijing" --dep-date 2026-05-01 --dep-hour-start 5 --dep-hour-end 9 --sort-type 6

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.

Early morning flights (5-9 AM) are often 10-20% cheaper than midday. Best for same-day business trips. Arrive by lunch, full afternoon ahead. Consider airport proximity — early flights from secondary airports (SHA vs PVG) may be more convenient.
