The empty description reduces confidence slightly, but the naming convention is clear. Severity is low because listing customers has minimal blast radius — it retrieves existing data without side effects.
From the tool's definition Tool name 'linear_list_customers' indicates a list operation that retrieves customer data. The 'list' verb is characteristic of Read operations that query or retrieve data without modification.
