Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden, and it discloses almost nothing. It does not say that these are mutating operations on a service, whether restarting drops existing bans, what permissions are needed, or what happens to in-flight blocks. The word 'Operate' plus the enum is all the behavioral signal provided.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
