Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. The verb 'Delete' does reveal the destructive intent, but nothing is said about whether deletion is permanent, what happens when the ID does not exist, whether referenced records are affected, or any permission requirements. This is a meaningful gap for a destructive operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
