## Why check_balance is rated Low

This tool only retrieves information about account state without creating, modifying, or moving funds. It is a pure read operation analogous to a balance inquiry. While it occurs in a financial system (remit.md), the tool itself performs no financial transactions or state changes. Severity is low because unauthorized balance checks pose minimal direct harm compared to payment or fund movement capabilities.

From the tool's own definition: "Tool name is 'check_balance' and description states it checks 'your current USDC wallet balance' — a query operation with no side effects."

## Use case
