 ## Unreleased
+- Align AgentSpanData test stubs and span processor with real OpenAI Agents SDK;
+  remove non-existent `operation`, `description`, `agent_id`, and `model` fields.
+  ([#4229](https://github.com/open-telemetry/opentelemetry-python-contrib/pull/4229))
 - Document official package metadata and README for the OpenAI Agents instrumentation.
