Longbridge

Overview

Longbridge is the official skill collection for Longbridge Securities, covering a separately maintained set of 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).

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

Scope and data verification

AAS bundles this guide only, not the upstream collection or CLI. Inspect the actual installed version/tool schemas and current data entitlements. Verify market, exchange, currency, timestamp, delay and corporate-action adjustments; broad language support does not establish symbol coverage. Use existing scoped credentials. Reading a portfolio does not authorize orders, watchlist changes, transfers or broader trading permissions. Keep account data private and do not send it to another provider without consent.

How It Works

Step 1: Discover the Right Subcommand

longbridge --help

List all available subcommands. Never hard-code subcommand names — the CLI evolves.

Step 2: Check Subcommand Options

longbridge <subcommand> --help

Confirm flags and output format before calling.

Step 3: Call with JSON Output

longbridge <subcommand> --format json

Parse the structured output and render in the user's language (detect from input).

Authentication

longbridge auth login          # Basic market data (read-only)
longbridge auth login --trade  # Portfolio and account features

Install

# 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.
• The default task is read-only. A trade-capable token is not authorization to place an order; exact account, instrument, side, quantity, order terms and costs require an explicit authorized action and timeout reconciliation.

Security & Safety Notes

• Inspect the actual command schema and effects before execution. Data retrieval may use network requests, rate limits and paid entitlements even when it does not mutate an account.
• Require an authorized preview and confirmation for watchlist or order mutations; do not assume the installed integration enforces a two-step protocol.
• Use the installed auth system and verify its credential storage. This guide does not establish how a separate CLI stores or transmits tokens.
