Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint and non-destructive behavior. The description adds minimal context by mentioning 'status summary,' but it doesn't disclose additional behavioral aspects such as authentication requirements or result ordering. With annotations covering safety, a 3 is appropriate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
