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 discloses the key non-invasive behavior ('without touching the target'), which is valuable, but omits prerequisites (active session), error behavior, and whether it alters or consumes session state.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
