Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly identifies the tool as returning metadata about every field in the Business Grants Finder enquiry, listing the specific attributes (key, label, type, required, help text, options). The title reinforces this. It does not use an explicit verb like 'retrieve' or 'list', and it does not explicitly contrast itself with 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.
