Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of disclosing behavior. It mentions a pagination limit of 50 results per page but does not specify if pagination is supported or how to access additional pages. There is no mention of read-only nature, authorization needs, or side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
