Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false. Beyond that, the description meaningfully adds that the person remains in the network and that suggestions may recur — which are non-obvious behavioral consequences for a destructive operation. It does not fully detail what happens to other list memberships or whether removal cascades, but the key semantic boundary is disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
