Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'Get popular assets' and reveals nothing about side effects, ordering, pagination behavior, authentication requirements, or what constitutes 'popular.' This is a significant transparency gap for any tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
