Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits but only says 'Show', implying a read operation without specifying return format, error behavior, or side effects. It does not clarify whether it returns content, metadata, or how version existence is handled.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
