Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered. The only behavioral claim the description makes is "(one page)", which gestures at a pagination boundary but never says whether results are truncated, what the default limit is, or how to page further — leaving the one piece of genuinely new behavior ambiguous.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
