Stock Price Query Skill

Stock Price Query Skill: 实时股票行情与大盘指数查询技能，覆盖 **A 股（沪深两市）**、**港股**、**美股**三大市场。支持**单只查询**和**批量查询**（一次查询多只股票对比），轻量无依赖，无需 API Key，适合聊天场景下的快速股价查询——秒级获取当前价格、涨跌幅、开高低收、成交量等行情数据。

This skill executes a Python script (`stock_query.py`) using `python3`. It takes stock codes (single or comma-separated for batch) and an optional market identifier as arguments. The script is designed to query real-time stock data for A-shares, Hong Kong, and US markets, including indices, by contacting unspecified 'free public market APIs' over the network.
