Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, and the word 'Read' aligns with them. The description adds useful context that the profile is public and enumerates returned metrics, but it does not disclose error behavior, availability guarantees, or other traits beyond the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
