PR Review: Minor updates for ntbk viz

I've completed my review of this pull request. Here's my comprehensive feedback:

Summary

This PR adds significant improvements to the notebook visualization with:

• New utility file: notebooks/utils.py with Rich formatting functions
• Enhanced notebook outputs: Better formatting and visualization across all 5 notebooks
• Updated dependencies: More specific version constraints for OpenAI packages

✅ Strengths

1. Excellent Code Quality in utils.py

• Well-structured utility functions for message formatting
• Good error handling and type annotations
• Clean abstraction with backward compatibility (format_message alias)
• Rich library integration for enhanced terminal output

2. Comprehensive Notebook Enhancements

• Consistent use of new show_prompt() function for better visualization
• Proper import statements and autoreload configuration
• Well-structured examples across all educational notebooks

3. Improved Documentation Flow

• Notebooks now have better visual hierarchy with formatted outputs
• Code examples are more readable with Rich formatting
• Progressive learning structure from basic concepts to advanced features

🔍 Review Findings

Code Quality: EXCELLENT

• No security vulnerabilities found
• Clean, well-documented code
• Proper separation of concerns
• Good use of type hints and docstrings

Performance: GOOD

• Rich formatting adds minimal overhead
• Efficient message processing functions
• No performance bottlenecks identified

Dependencies: GOOD

• pyproject.toml changes are sensible:
  • Added specific OpenAI version constraint (>=1.100.1)
  • Updated langchain-openai version (>=0.3.30)
• Rich dependency already included
• Version constraints help ensure compatibility

Testing: NO ISSUES

• Changes are primarily educational/visualization improvements
• No test coverage gaps introduced
• Existing test suite should remain unaffected

💡 Minor Recommendations

1. Consider adding docstring examples: The utils.py functions could benefit from usage examples in docstrings

2. Type hints enhancement: Consider using more specific types like List[BaseMessage] instead of generic lists where applicable

3. Error handling: The format_message_content() function handles different message types well, but could log warnings for unknown types

🎯 Overall Assessment

APPROVED ✅

This is a high-quality improvement that:

• Enhances the educational value of the notebooks significantly
• Introduces no security or performance concerns
• Follows good coding practices throughout
• Maintains backward compatibility
• Improves the developer experience substantially

The changes are well-executed and will make the repository's educational content much more accessible and visually appealing.
