2-2: LGTM!The
Iteratorimport is appropriately added to support the new streaming functionality.
54-74: Well-implemented streaming functionality!The new
run_streammethod cleanly extends the QAStep class with streaming capabilities while maintaining consistency with the existingrunmethod. The implementation correctly yields chunks from the underlying chat session's streaming method.graphrag_sdk/chat_session.py (6)
26-38: Excellent documentation improvements!The expanded examples clearly demonstrate both the full QA pipeline and standalone Cypher query generation use cases. This will help users understand the different ways to interact with the chat session.
41-96: Good architectural improvements!The constructor changes enhance the design by:
- Making configuration explicit through well-documented parameters
- Initializing steps once for better performance
- Properly separating concerns by extracting ontology cleaning
The persistent step instances will improve efficiency by avoiding repeated instantiation.
108-112: Clean helper method!Good refactoring to centralize the response update logic, ensuring both the session and cypher step stay synchronized.
157-179: Clean refactoring of send_message!The method now properly leverages the refactored components:
- Uses the public
generate_cypher_querymethod- Utilizes the persistent
qa_stepinstance- Correctly handles error cases
- Updates the response using the centralized helper
191-212: Excellent streaming implementation!The refactored streaming method properly:
- Leverages the new
qa_step.run_streammethod- Ensures the complete response is captured from chat history
- Maintains consistency with the non-streaming method
- Updates the last response after streaming completes
214-239: Good extraction of ontology cleaning logic!The standalone function properly encapsulates the ontology cleaning logic, making it reusable and testable. The implementation correctly removes the 'unique' and 'required' attributes as intended.

26-38: Great documentation improvements!The expanded examples clearly demonstrate both the full QA pipeline and standalone Cypher query generation, making the API more accessible to users.
84-96: Excellent refactoring for performance optimization.Initializing the QA and cypher steps once during construction instead of per-call instantiation is a significant performance improvement. This centralizes step management and eliminates unnecessary object creation overhead.
143-179: Well-structured message handling implementation.The method correctly:
- Uses the persistent QA step instance for better performance
- Handles error cases with appropriate fallbacks
- Maintains consistent response structure
- Updates the last complete response for state management
181-212: Solid streaming implementation.The streaming method properly:
- Handles cypher generation errors with early return
- Uses the new
run_streammethod from the persistent QA step- Correctly extracts the final answer from chat history
- Maintains state consistency with the last complete response
108-111: Good addition for state management.This helper method follows DRY principles by centralizing the logic for updating both the session's last complete response and the cypher step's last answer, ensuring consistent state management.
