Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the behavioral transparency burden. It only says 'List' and does not disclose whether results are paginated, sorted, limited, or whether any authorization constraints apply. It also does not clarify whether 'configured VLAN interfaces' includes only active VLANs or all defined ones.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
