Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must bear the full burden of behavioral disclosure. It only states that a list is retrieved, implying a read operation, but it does not describe response format, filtering behavior, pagination, or any potential side effects. This is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
