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

• 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.

Module Overview

Routing Rules

MCP Tools

This skill uses the CrossEx MCP toolset with the cex_crx prefix as its only core tool family.

Scope rule: Only execute operations explicitly documented in this skill. Only call tools listed in the tables below

or in references/*.md. Tools or operations not mentioned here must not be called.

Tool Naming Convention

• List operations in the cex_crx family query symbols, orders, positions, transfers, or history
• Get operations in the cex_crx family query a single account setting, fee, rate, or order detail
• Create operations in the cex_crx family create an order, transfer, convert quote, or convert order
• Update operations in the cex_crx family update account settings, leverage, or existing orders
• Cancel operations in the cex_crx family cancel an existing order
• Close operations in the cex_crx family close an existing position

Usage Guidance

• Use the cex_crx MCP family as the default and only core MCP family for this skill.
• Use list/get tools to query symbol rules, fees, balances, leverage, or supported assets.
• Prefer history and account-book tools when the user asks for records, audit trails, or status verification.

Execution

1. Intent and Parameter Identification

• Determine module (orders/positions/history)
• Extract key parameters:
• Trading Pair: GATE_SPOT_BTC_USDT, GATE_MARGIN_XRP_USDT, GATE_FUTURE_ETH_USDT
• Exchange: GATE, BINANCE, OKX, BYBIT
• Direction: BUY (buy/long), SELL (sell/short)
• Quantity: USDT amount, coin quantity, contract size
• Price: Limit, market
• Leverage: Leverage multiplier (margin/futures only)
• Position Side: LONG (long), SHORT (short, margin/futures only)
• Missing Parameters: If required parameters are missing, ask user

2. Pre-checks

• Trading Pair: Call cex_crx_list_crx_rule_symbols to verify
• Account Balance: Call cex_crx_get_crx_account to check if available margin is sufficient

Safety Rules

• Credentials: Never prompt or induce the user to paste API Secret Key into chat; prefer secure local MCP configuration.
• User-to-User Transfer: This skill does not support P2P or user-to-user transfers; only transfers between the user's own accounts (e.g., SPOT ↔ CROSSEX) are allowed.
• Trade Orders: Display complete order summary (pair, direction, quantity, price, leverage), require user

confirmation before placing order

• Cross-Exchange Transfer: Display transfer details (source, destination, quantity, arrival time), require

confirmation

• Scope rule: Only call tools documented in this skill. If the user requests an operation not documented here,

respond that it is not supported by this skill.

• Batch Operations: Display operation scope and impact, require explicit confirmation

Example: "Reply 'confirm' to execute the above operation."
