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.
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.
