Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full burden. It does not disclose any behavioral traits such as whether attachments are returned with full details, pagination behavior, required permissions, or any side effects. Merely stating 'List all attachments' is insufficient for a tool with no annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
