Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It mentions 'Uses QE DOM' but does not disclose whether the operation is read-only, has side effects, or requires specific permissions. A simple listing tool likely is read-only, but that is not stated.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
