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 by structured data. The description adds only the REST endpoint path (GET /api/config-profiles/inbounds); it says nothing about pagination, ordering, or size of the returned collection for an unbounded 'all profiles' read.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
