Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare the operation as read-only and non-destructive, covering the safety profile. The description adds useful context about what is returned (standings sorted by wins then points for, with team and manager names), but it does not disclose limitations or edge-case behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
