Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly identifies the resource ('every field of the Mail Merge PDF enquiry') and enumerates the attributes it exposes (key, label, type, required, help text, allowed options). The verb is implicit rather than explicit, but the scope is unambiguous. It makes a partial distinction from submit_enquiry, though not from the other sibling tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
