Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It indicates a read-only operation ('List') and specifies the scope ('active') and output ('status'), but it doesn't elaborate on side effects, prerequisites, or the nature of the returned data. This is minimal but not misleading.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
