Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare readOnlyHint=true, destructiveHint=false, and closed-world scope, so the safety profile is covered. The description adds that this is a rules/information tool rather than an action, but gives no sense of return format or freshness of the content it serves.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
