Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare the safe read profile (readOnlyHint, idempotentHint, destructiveHint=false, openWorldHint=false), so the description's added value is the sort order ('newest first') and the returned content ('status, compliance state, page counts and what each counted on audit.capture'). It does not disclose pagination or truncation behavior at the 50-item cap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
