Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. 'Get details' implies a read-only operation, but the description does not disclose what 'details' includes, error behavior, or any side effects. It adds minimal context beyond the action itself.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
