Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description adds the HTTP route, which usefully reveals that share links are per-report, but says nothing about pagination, ordering, or whether revoked links are included.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
