Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It only notes this is a read operation, but does not explain the presence of mutationApproved or responseMode parameters, pagination, filtering, or security requirements. The inclusion of a mutation-related parameter in a read tool is confusing and not clarified.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
