Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false, signaling a mutating operation, and the schema requires confirm=true for execution. The description adds only the 'temporary' scope and does not describe side effects, reversibility, or what happens after deletion, but the annotation coverage lowers the burden.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
