Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare destructiveHint=true and readOnlyHint=false, and the description goes well beyond that: it says withdraw stops gateway serving while leaving the published version untouched, restore requires no new review, and the operation is owner-only. Reversibility, blast radius, and auth requirement are all disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
