2137With OpenTelemetry, the Claude SDK can emit a span for each request that it sends and each tool use that the [tool runner](https://platform.claude.com/docs/en/agents-and-tools/tool-use/tool-runner) runs. You can view these spans in your observability platform, nested in your own traces.
from line 673
657673| Requests from the SDK don’t have a `traceparent` header | Register the W3C trace context propagator with OpenTelemetry. The SDK writes the headers with your application’s propagator. |
658674| A stream’s SDK span doesn’t end or doesn’t have the response | See [Tracing a stream](https://platform.claude.com/docs/en/manage-claude/opentelemetry/sdk#trace-a-stream). |
659675| Each request appears twice | A request’s SDK span and API span have the same name. Use the span kind or `service.name` to tell them apart. If another library also traces the SDK, turn off one of the two. |

693* Availability: Available
694* Usage: The SDK traces the requests that your code sends, such as the events you send to a session; spans for the agent’s model requests and tool calls come from API tracing. In a self-hosted sandbox, the SDK’s environment worker also traces each tool it runs.
