Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered structurally. The description adds nothing beyond that: no indication of what FAQ content is returned, whether it is static or account-scoped, or whether it is paginated. With annotations carrying the burden, the description still contributes zero additional behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
