Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must carry the full behavioral disclosure burden; it only says 'List all pending and resolved approval requests' and does not state read-only behavior, pagination, ordering, required permissions, or any side effects. The verb 'List' hints at a read operation, but the description provides minimal behavioral context beyond that.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
