Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description itself must convey safety and behavior. "Get information" clearly indicates a read-only operation, and "current view state" suggests a non-mutating snapshot. However, it does not disclose the return format, whether nulls/empty selections are possible, or how the view state is structured, leaving some ambiguity.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
