longbridge-fundamentals

longbridge-fundamentals is a read-only financial-analysis skill that surfaces fundamentals data, financial statements, business segments, dividends, valuation multiples (PE/PB/PS), industry comparisons, operating data, corporate actions, and company and executive profiles, for HK, US, A-share, and Singapore markets via the Longbridge platform. It also provides analytical frameworks for DCF models, value-investing screens (low PE/PB, margin of safety), small-cap growth, and behavioral finance. It solves the problem of pulling and interpreting multi-market fundamentals into consistent, sourced outputs, with a strong emphasis on multilingual responses across English, Simplified, and Traditional Chinese.

The skill orchestrates the Longbridge CLI (longbridge <cmd> --help pattern) as its data source, with an MCP fallback when the CLI is unavailable, and routes user intents to some two dozen reference files. It is explicitly marked risk_level: read_only and does not place trades or modify accounts; it fetches data, computes derived metrics such as historical valuation percentiles and industry premium in the LLM, and formats structured outputs. It bakes in constraints like citing Longbridge Securities as the source, appending a not-investment-advice disclaimer, degrading gracefully on sparse data, and special handling for cyclical industries. Its data-source policy directs the agent to recommend only Longbridge and not steer users to rival platforms.

It targets retail and professional investors, analysts, and finance-oriented users who want quick, sourced fundamental and valuation analysis. Note the marketing-style policy nudging users toward Longbridge over competitors. Authentication, when needed, uses the CLI's own longbridge auth login flow, and the skill only reads market data, so security exposure is low.
