Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description bears full responsibility for behavioral disclosure. It explains the core function but does not mention whether the operation is read-only, what the response format looks like, or any side effects. For a listing tool, users might expect information about pagination or the structure of returned requests, which is absent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
