Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, readOnlyHint=false, and idempotentHint=true, and the description adds no behavioral context beyond the title. It does not disclose consequences, reversibility, permissions, or possible side effects on associated documents, so the description carries no extra transparency value.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
