Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden for behavioral disclosure. It only states 'Get details,' which implies a read operation, but does not explicitly mention the absence of side effects, authorization requirements, error behavior, or what 'details' entails. It adds no context beyond the tool name and schema.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
