Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must bear the full burden of behavioral disclosure. It fails to mention that this is a read-only operation, any permissions required, pagination behavior, or response format. The bare statement 'List ELB health monitors' is insufficient for an agent to understand side effects or limits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
