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. It usefully states that the rating being deleted belongs to the authenticated user, which clarifies authorization scope. However, it does not disclose whether deletion is idempotent, what happens if no rating exists, or any response behavior, leaving notable gaps 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.
