Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations to provide safety or side-effect information, so the description carries the full burden. It only says 'enable/disable ACL rule' and does not disclose whether the rule must exist, whether it is idempotent, or what happens if the rule is already in the desired state. This is a significant gap for a mutating operation without any behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
