Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of behavioral disclosure. It communicates that the tool exposes all enquiry fields and their metadata, implying a read-only metadata lookup. It does not discuss side effects, authentication, or whether the data is static or dynamically generated, but for a simple field-listing tool the description is not misleading.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
