Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden for behavioral disclosure, but it only states that it retrieves a list. It does not explicitly state that it is read-only, whether authentication is required, or any details about the response. The GET method is a weak implicit signal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
