Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly identifies the resource ('the Malta Work Permit Checker enquiry') and the content delivered: key, label, type, required flag, help text, and allowed options. It is not phrased with an explicit verb like 'returns' or 'lists', but the title and sentence together leave little doubt. It does not explicitly differentiate from the sibling enquiry_describe, so it stops short of a 5.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
