Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full weight for behavioral disclosure. It implies a read-only operation via the verb 'Get' and lists sample response attributes, which provides some context. However, it does not mention error handling, required permissions, or any side effects (though none are obvious for a system info tool). This is a minimal but acceptable disclosure for a simple getter.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
