Cross-Skill Workflows

Before trading: User asks "Can I buy 100U BTC?" → This skill: cex_spot_get_spot_accounts currency=USDT → Route to gate-exchange-spot if sufficient.
After transfer: Route to this skill for updated balance when user asks.
Transfer card: When futures/options = 0, recommend [Transfer] and trigger transfer skill.

Safety Rules

Read-only only. Never call create_order, cancel_order, create_transfer, or any write operation.
If user intent includes trading, transfer, or order placement → route to appropriate skill.
Always clarify currency and scope (spot vs all wallets) when ambiguous.
