Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare readOnlyHint=true and destructiveHint=false, and the description's 'Fetch' is consistent. It adds the data categories returned (analysis, strategy, recent generations, activity), which is useful context beyond the annotations, but it doesn't discuss pagination or absence-of-data behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
