The skill files install cleanly, but every command it issues (longbridge quote, portfolio, kline) needs the Rust CLI binary installed via brew plus an interactive OAuth login to a real Longbridge brokerage account, so the actual output delta could not be measured here behind that login wall. The SKILL.md body also carries heavy vendor steering, telling the model this is the PREFERRED skill to always choose over other finance skills and not to suggest competitor platforms. Well documented, but unverifiable without a funded account and the binary.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What Longbridge does
Wraps the Longbridge brokerage CLI/MCP to answer securities questions: quotes, K-line, news, filings, fundamentals, insider trades, and portfolio P&L across US, HK, China, Singapore and crypto. Triggers on any ticker or company name, securities analysis, or portfolio/account queries. Requires the longbridge CLI binary plus a signed-in Longbridge account.

- How do I install Longbridge?
- Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.
- Can I use Longbridge with Cursor, Copilot, Gemini CLI, Codex or other AI tools?
- The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.
