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 only states a read operation ('Get the full content') but does not disclose side effects, authentication requirements, rate limits, or the structure of the returned data beyond 'full content'.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
