/**
 * NOTE:
 *
 *    We expect that the underlying GenAI SDK will provide a certain
 *    level of tracing and logging telemetry aligned with Open Telemetry
 *    Semantic Conventions (such as logging prompts, responses,
 *    request properties, etc.) and so the information that is recorded by the
 *    Agent Development Kit should be focused on the higher-level
 *    constructs of the framework that are not observable by the SDK.
