Logistics

Overview

Use this skill to help the user track parcels, identify couriers, interpret logistics statuses, and understand what a shipment update usually means. It serves as a unified entry point for multi-courier logistics queries, including major Chinese courier networks such as SF Express (顺丰), JD Logistics (京东快递), ZTO (中通), Cainiao (菜鸟), J&T Express (极兔), and others.

Workflow

1. Identify whether the user has:
   • one tracking number
   • multiple tracking numbers
   • an unknown courier
   • a status they want explained
2. If the courier is unknown, infer cautiously from the number pattern or context.
3. Return the latest useful tracking interpretation first.
4. If a package appears delayed, explain likely reasons and a reasonable next action.
5. Keep summaries concise when handling multiple shipments.
