Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden, and it discloses nothing: not what HTML is returned (outerHTML of the matched node?), not whether it is a live read or a cached snapshot, and not the interaction with frames or page state. "(alias)" adds ambiguity rather than behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
