Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description bears full responsibility. It states 'list all alerts,' implying a read-only operation, but provides no details about pagination, rate limits, authentication requirements, or error behavior. The lack of any behavioral disclosure beyond the basic operation leaves the agent uninformed about important constraints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
