Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds essentially nothing beyond that: no ordering (audit logs are usually reverse-chronological), no retention window, no indication of what fields 'who changed what' returns. 'Who changed what' is a marginal hint at content, not real 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.
