Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly identifies the tool as providing every field of the Get 409A Valuation enquiry and enumerates exactly what each entry includes: key, label, type, required status, help text, and allowed options. It stops short of an explicit verb like 'lists' or 'returns', and it does not differentiate itself from the sibling enquiry_describe, so it misses a 5.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
