Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds that it returns a single prioritized item rather than a list and that it includes a handoff, which is genuinely useful beyond the annotations, but it stops short of explaining what the handoff contains or how the item is ranked.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
