Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description carries the full burden of behavioral disclosure. It reveals one behavior, optional filtering by a tag value, but does not state whether the operation is read-only, what the response looks like, what happens without filters, or any side effects or error conditions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
