Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. 'List all bounces' implies a read-only operation but doesn't specify permissions, rate limits, pagination behavior, or what 'all' entails (e.g., time range, filtering). It lacks critical context for safe and effective use.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
