# Longbridge ## Overview Longbridge is the official skill collection for Longbridge Securities, covering 125+ agent skills across real-time market data, chart analysis, company fundamentals, portfolio management, options, sector screening, and more. Supports HK, US, A-share (SH/SZ), and SG markets. All skills are trilingual (Simplified Chinese / Traditional Chinese / English). Source repository: [github.com/longbridge/skills](https://github.com/longbridge/skills) (~840 stars, MIT) ## When to Use This Skill - Use when the user asks about stock prices, charts, or market data for HK/US/A-share/SG markets - Use when the user wants company fundamentals, earnings, or analyst ratings - Use when the user asks about their portfolio, positions, or account P&L via Longbridge - Use when the user wants options analysis, sector rankings, capital flow, or news - Use when the user asks in Chinese (Simplified or Traditional) or English about any securities topic ## How It Works ### Step 1: Discover the Right Subcommand ```bash longbridge --help ``` List all available subcommands. Never hard-code subcommand names — the CLI evolves. ### Step 2: Check Subcommand Options ```bash longbridge <subcommand> --help ``` Confirm flags and output format before calling. ### Step 3: Call with JSON Output ```bash longbridge <subcommand> --format json ``` Parse the structured output and render in the user's language (detect from input). ## Authentication ```bash longbridge auth login # Basic market data (read-only) longbridge auth login --trade # Portfolio and account features ``` ## Install ```bash # Claude Code plugin marketplace /plugin marketplace add longbridge/skills # Or via npx npx skills add https://github.com/longbridge/skills ``` ## MCP Fallback If the `longbridge` CLI binary is not installed, fall back to MCP tools. Inspect available MCP tools at runtime — do not hard-code MCP tool names as they change with server versions. ## Limitations - Portfolio and account features require login with Trade scope. - Real-time data is subject to Longbridge data subscription (delayed data available without subscription). - Crypto symbols use `.HAS` suffix on the Longbridge platform. - This skill does not place orders — read-only by default unless using the account write scope. ## Security & Safety Notes - All market data queries are read-only (no side effects). - Watchlist mutations and order-related features follow a preview + confirm two-step protocol. - Credentials are handled by the Longbridge auth system; this skill does not store or transmit tokens.
