Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered by structured data. The description adds only that the cards are current and derive from the 'Rasadi insight engine', which is modest context beyond the annotations. It does not disclose ordering, freshness window, or volume of cards returned.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
