Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds that it never returns the page body or password, which is useful. However, it doesn't mention potential errors (e.g., slug not found, permission issues) or pagination (not relevant here). 3 is appropriate given annotations already cover the read-only behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
