Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, readOnlyHint=false and non-idempotent, so the danger is signposted structurally. The description adds the meaningful governance constraint that a human must pick the strategy, but it never says which memories are destroyed, whether resolution is reversible, or that the default strategy is mark_conflict.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
