Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so the read-only nature is known. The description adds the org-scoped scope and endpoint, which is useful context, but does not disclose any additional behaviors such as pagination, rate limits, or response shape. This mirrors the 'high' example where annotations plus scope earned a 3.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
