Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It usefully discloses that the result depends on the live UI selection state ('currently selected'), which is non-obvious behavioral context, but it omits what happens when nothing is selected or whether the list can be empty.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
