Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The readOnlyHint annotation already declares this as a safe read operation, so the description does not need to repeat that. However, the description adds no extra behavioral context such as whether it returns full configuration details, whether authentication is required, or any side effects. It is consistent with the annotation but offers minimal added value beyond 'get'.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
