WHAT IT DOES

Parameters from the server's own tool schema.

RISK

Why util_ends_with is rated Low

Even though util_ends_with only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
