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."

Error Handling

Error Code	Handling
`USER_NOT_EXIST`	Please confirm if a GATE CrossEx account has been opened. Refer to the GATE Help Center -> CrossEx Trading -> CrossEx Account Operation Guide for instructions.
`TRADE_INVALID_QUOTE_ORDER_QTY`	⚠️ Incorrect parameter name: Market buy must use `quote_qty`
`TRADE_INVALID_ORDER_QTY`	⚠️ Limit order error: Limit orders must use `qty` (coin quantity) + `price`
`TRADE_ORDER_AMOUNT_MIN_ERROR`	Order amount below minimum notional value (typically 3 USDT), increase quantity or amount
`CONVERT_TRADE_QUOTE_EXCHANGE_INVALID_ERROR`	⚠️ Flash convert: `exchange_type` parameter value must be uppercase exchange code (e.g., `GATE` )
`TRADE_MARGIN_INVALID_PZ_SIDE_ERROR`	Prompt that margin/futures trading must specify `position_side` (LONG/SHORT)
`BALANCE_NOT_ENOUGH`	Insufficient available margin, suggest reducing trade amount or depositing
`SYMBOL_NOT_FOUND`	Confirm trading pair format is correct (e.g., GATE_SPOT_BTC_USDT)
`INVALID_PARAM_VALUE`	Check parameter format (qty is numeric string, position_side is LONG/SHORT)
`POSITION_NOT_EMPTY`	Prompt to close position before reversing direction
`TRADE_ORDER_LOT_SIZE_ERROR`	Suggest adjusting quantity to minimum unit of the trading pair
`RATE_LIMIT_EXCEEDED`	Prompt user about rate limit; suggest retrying later or reducing request frequency
