Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The readOnlyHint annotation already establishes that this is a safe read operation, and the description does not contradict it. However, the description adds no behavioral context beyond the annotation, such as whether content may be empty, what form the content takes, or whether any permissions are required.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
