Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full disclosure burden and delivers almost none of it: it does not say whether the selection replaces or adds to the current one, whether hidden/collapsed items can be selected, whether the panel is scrolled to reveal the items, or what is returned. Only the panel scoping ('Project panel') is conveyed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
