How It Works

Step 1: Discover the Right Subcommand

longbridge --help
Copy

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

Step 2: Check Subcommand Options

longbridge <subcommand> --help
Copy

Confirm flags and output format before calling.

Step 3: Call with JSON Output

longbridge <subcommand> --format json
Copy

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
Copy

Install

# Claude Code plugin marketplace
/plugin marketplace add longbridge/skills

# Or via npx
npx skills add https://github.com/longbridge/skills
Copy

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.
