Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, and the description adds context by defining macros and citing the REST endpoint. However, it does not disclose pagination behavior, response format, or any other side effects. The description is consistent with the read-only annotation and adds minimal extra behavioral context, so a 3 is appropriate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
