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.
