Fly Flight

Use the unified transport entrypoint in this skill to handle China domestic trip lookup for both flights and high-speed rail.

这是一个统一的中国境内出行查询 skill，同时支持航班和高铁。 它通过同一个 transport 入口按 mode 路由到底层 provider。

Requirements

Require the following runtime environment before using this skill:

• python3
• node
• Network access to Tongcheng public flight pages and official 12306 public endpoints

使用这个 skill 前，运行环境必须具备：

• python3
• node
• 能访问同程公开航班页面和 12306 官方公开接口的网络环境

These dependencies are required whether the skill is installed from GitHub or from ClawHub.
无论这个 skill 是从 GitHub 安装还是从 ClawHub 安装，这些依赖都必须满足。

Current implementation status:

• flight mode is implemented through Tongcheng public flight pages.
• train mode is implemented through official 12306 public high-speed rail query and public price endpoints.

Quick Start

Flight query:

python3 {baseDir}/scripts/transport_service.py search \
  --mode flight --from 北京 --to 上海 --date 2026-03-20 --sort-by price --pretty

High-speed rail query:

python3 {baseDir}/scripts/transport_service.py search \
  --mode train --from 北京 --to 上海 --date 2026-03-20 \
  --seat-type second_class --sort-by price --pretty

The legacy flight-only entrypoint remains available for backward compatibility:

python3 {baseDir}/scripts/domestic_flight_public_service.py search \
  --from 北京 --to 上海 --date 2026-03-20 --sort-by price --pretty

Optional local HTTP mode:

python3 {baseDir}/scripts/transport_service.py serve --port 8766

Workflow

1. Determine transport mode. Use flight for flights, airports, airlines, or plane tickets. Use train for high-speed rail, rail tickets, stations, or train numbers. If the user is ambiguous, infer conservatively from their wording or ask.

2. Route to the correct provider. Use scripts/transport_service.py as the shared entrypoint. Flight mode delegates to scripts/providers/flight_public_service.py. Train mode delegates to scripts/providers/train_public_service.py.

3. Preserve a shared outer response shape. Return mode, provider, trip_type, outbound, and optional return. Keep mode-specific fields inside each leg's options.

4. Apply only mode-specific filters that make sense. Flight filters: airline, direct-only, preferred airports. Train filters: train type, seat type, preferred stations.

5. Summarize results with the mode label. Clearly say whether the result is a flight result or a train result. Treat public-source prices as reference prices that can differ from final checkout prices.

Output Rules

• Prefer up to 5 options unless the user asked for more.
• State the exact travel date in YYYY-MM-DD.
• Keep the outer response consistent across modes.
• Do not force a single shared field schema for airports and stations; keep mode-specific details inside options.
• For round trips, clearly separate outbound and return.
• For train mode, explain that prices come from official public fare data and seat availability comes from public query results.

Resources

• Use scripts/transport_service.py as the unified CLI and HTTP entrypoint.
• Use scripts/providers/flight_public_service.py for flight lookups.
• Use scripts/providers/train_public_service.py for high-speed rail lookups.
• Use scripts/domestic_flight_public_service.py only for backward compatibility.
• Use scripts/extract_tongcheng_state.js to decode the Tongcheng public page payload.
• Use references/provider-public-web.md for public-source notes and limitations.
