This tool retrieves eligibility status information about a user's TRX withdrawal availability. It performs no state modifications, does not execute code or commands, does not delete data, and does not involve financial transactions. It is purely informational and carries minimal risk if misused by an AI agent, as it cannot cause harm beyond potentially exposing eligibility status information.

From the tool's own definition: "Tool name and description indicate a query operation: 'Check if user has TRX available to withdraw'. The verb 'check' and the read-only nature of determining eligibility status confirm this is a data retrieval operation with no side effects."
