Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations present, the description carries the full burden for behavioral disclosure. It only states the tool returns a signature, omitting details about return structure, safety, side effects, or error behavior. The 'get' in the name implies a read operation, but this is not explicitly stated.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
