Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. While 'List' implies a read operation, it doesn't mention whether this requires authentication, what format the results come in, whether it's paginated (though the page parameter suggests it is), or any rate limits. The description is minimal and leaves important behavioral aspects unspecified.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
