Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and openWorldHint=true, so the tool is safe and result variability is expected. The description adds detail on the output contents (tags, scores, freshness), but does not discuss authorization needs, rate limits, or other behavioral aspects beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
