Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses that the tool returns the scheduler status as one of three states, which is useful. However, since no annotations are present, the description carries full burden and omits details like whether the operation is read-only, requires permissions, or has rate limits. It is adequate but not comprehensive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
