Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, readOnlyHint=false, and non-idempotent behavior, so the safety profile is covered elsewhere. The description adds nothing beyond that, saying nothing about downtime, dropped client connections, or loss of unsaved configuration/runtime state.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
