Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, idempotentHint=true, and openWorldHint=true, so the safety profile is covered by structured data. The description contributes nothing beyond that—no disclosure of what a terminology is, what dependent data is removed, or whether deletion is recoverable.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
