Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations present, the description bears full responsibility for behavioral disclosure. It only states what is returned and does not mention side effects (none expected, but not confirmed), authentication requirements, rate limits, or whether it is safe to call frequently. This is a significant gap for a tool that could have access implications.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
