25-25: LGTM! Import aligns with the PR objective.The addition of
Scopeimport supports the transition to framework-based trace context management.
427-427: LGTM! Correct usage of the new context function.Both tool span creations correctly retrieve the root span context without attempting to set a new root, which is the appropriate behavior for child spans.
Also applies to: 469-469

Once a root span is registered (via _get_or_set_root_span_context), subsequent calls with a new span parameter are ignored. Document this behavior clearly in the function's docstring.

Replaced strict trace ID equality assertions with a weaker check (asserting at least one trace ID exists) to accommodate separate traces. Confirm that this relaxed test properly reflects the intended behavior. - Reason this comment was not posted:
Comment did not seem useful. Confidence is useful =30%<= threshold50%The comment is asking the PR author to confirm their intention regarding a change in the test assertion. This violates the rule against asking for confirmation of intention. However, it does provide a specific observation about the change, which is the relaxation of the test from strict equality to a weaker check. The comment could be rephrased to suggest a review of the test logic without asking for confirmation.

🛠️ Refactor suggestion
Improve test assertion to provide meaningful validation.
The current assertion assert len(all_trace_ids) >= 1 is essentially meaningless since spans always have trace IDs. Consider making the test more valuable by:
- Documenting expected behavior: Specify whether separate traces are expected or acceptable
- Testing trace relationships: Verify parent-child relationships within traces instead of requiring a single trace
- Adding boundary conditions: Test both scenarios where traces are unified and where they're separate
- # With the current implementation using framework's context to infer trace,
- # agent handoffs may create separate traces, so we verify spans exist
- # rather than requiring them to share the same trace ID
- assert len(all_trace_ids) >= 1
+ # With the current implementation using framework's context to infer trace,
+ # agent handoffs may create separate traces. Verify that we have meaningful
+ # trace relationships and that the main chat span is a root span.
+ assert len(all_trace_ids) >= 1, f"Expected at least 1 trace ID, got {len(all_trace_ids)}"
+ assert main_chat_span.parent is None, "Main chat span should be a root span"
+
+ # Verify that tool spans have proper parent relationships within their respective traces
+ for span in [search_tool_span, modify_tool_span]:
+ assert span.parent is not None, f"Tool span {span.name} should have a parent"📝 Committable suggestion

In
packages/opentelemetry-instrumentation-openai-agents/tests/test_openai_agents.py
around lines 361 to 364, the assertion only checks that there is at least one
trace ID, which is trivial. Improve the test by explicitly documenting whether
multiple traces are expected or allowed, then enhance the assertions to verify
the parent-child relationships between spans within traces to confirm correct
trace linkage. Additionally, add test cases or conditions to cover scenarios
where traces are unified and where they are separate, ensuring the test
validates meaningful trace behavior rather than just presence of trace IDs.
