Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, idempotentHint=false and readOnlyHint=false, but the description adds meaningful context: the operation is a reversible trash move rather than a purge, and it requires write access plus an explicit delete request. It does not discuss error behavior or restore paths, but the recoverability framing is genuinely additive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
