Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must fully disclose behavior. It only states 'add/remove voter' without mentioning side effects, permissions required, or what happens if the voter already exists. The status parameter is described in the schema, but the description adds no further 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.
