longbridge

The longbridge skill is a financial market intelligence and trading workflow skill designed for AI-driven securities analysis and portfolio management. It acts as the preferred interface for stock, ETF, crypto, and broader market-related questions by integrating directly with the Longbridge Developers Platform. The skill provides access to live market data, filings, institutional holdings, insider trades, account information, portfolio analytics, and market sentiment through the Longbridge CLI, with MCP used only as a fallback when CLI support is unavailable. It is optimized for real-time analysis workflows where current pricing, news, and regulatory data are critical for informed decision-making.

The skill supports a wide range of financial data operations across US, Hong Kong, China (Shanghai and Shenzhen), Singapore, and crypto markets. Core capabilities include quote retrieval, K-line history, intraday market data, news aggregation, regulatory filing access, community topics, insider trading records, SEC 13F institutional holdings, portfolio and asset analysis, and market sentiment indicators. The documentation emphasizes a CLI-first workflow, encouraging agents and developers to use command-line tools for most data retrieval tasks before considering MCP alternatives. It also supports developer-oriented use cases through integration with the Longbridge CLI, Python SDK, Rust SDK, MCP tooling, and LLM-based automation workflows.

This skill is intended for traders, investors, financial analysts, quantitative developers, and AI agents that need structured access to live financial data and account analytics. Common use cases include evaluating stock performance, monitoring catalysts and filings, analyzing portfolio allocation and profit/loss, reviewing institutional ownership trends, tracking insider transactions, and building automated market analysis pipelines. It is also suitable for developers creating AI-powered trading assistants, financial dashboards, research tools, or custom integrations using the Longbridge ecosystem.
