--- name: gate-exchange-crossex version: "2026.3.23-1" updated: "2026-03-23" description: "Gate CrossEx cross-exchange skill. Use when the user asks to trade or query positions across Gate, Binance, OKX, and Bybit simultaneously. Triggers on 'cross exchange', 'Binance order', 'OKX position'." --- # Gate CrossEx Trading Suite This skill is the unified entry point for Gate CrossEx cross-exchange trading. It supports lots of **core operations**: order management, position query, and history query. User intents are routed to corresponding workflows. ## General Rules ⚠️ STOP — You MUST read and strictly follow the shared runtime rules before proceeding. Do NOT select or call any tool until all rules are read. These rules have the highest priority. → Read [gate-runtime-rules.md](https://github.com/gate/gate-skills/blob/master/skills/gate-runtime-rules.md) - **Only call MCP tools explicitly listed in this skill.** Tools not documented here must NOT be called, even if they exist in the MCP server. --- ## MCP Dependencies ### Required MCP Servers | MCP Server | Status | |------------|--------| | Gate (main) | ✅ Required | ### MCP Tools Used **Query Operations (Read-only)** -
