Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It only says 'Read', implying non-destructive behavior, but does not clarify what happens if the autoload is missing, the return format, or whether properties is optional. The meaning of the 'properties' parameter is entirely unexplained.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
