Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It states a read operation ('get'), implying it is likely safe and non-destructive, but does not cover permissions, rate limits, error handling, or return format, leaving significant gaps for a tool with unknown behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
