Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of disclosing behavioral traits. It merely says 'Get', which implies a read-only operation, but it does not explain what 'extended system properties' are, what the output looks like, or any potential side effects or required permissions. The absence of any such context is a significant gap for an unannotated tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
