Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered. The description adds that only a single pack is affected and that the name must match exactly, which is useful, but it never says what 'archive' actually does (hidden vs. deleted, reversible or not) or how a name mismatch fails.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
