Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, and the description merely repeats that this is a read operation via "[READ] GET". It adds no extra behavioral context such as authentication needs, rate limits, pagination, or what the endpoint returns.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
