🔍 PR Review Summary

I've conducted a thorough review of this pull request. Here are my findings:

✅ Strengths

• Well-structured codebase: The reactive programming library follows good Go practices with proper error handling, context propagation, and generic types
• Comprehensive documentation: Excellent documentation in docs/CLAUDE.md with clear guidelines for contributors
• Consistent patterns: Good use of operator patterns with variants (WithContent, I suffix for index variants)
• Proper error handling: Custom error types with unwrapping support and descriptive error messages
• Good abstractions: Clean separation between Observable, Observer, and Subscription interfaces

📋 Code Quality Assessment

• Architecture: Follows reactive programming principles with proper backpressure handling
• Naming conventions: Consistent and descriptive naming throughout the codebase
• Comments: Good inline documentation for exported functions and types
• Testing: Appears to have comprehensive test coverage with parallel test execution

🛡️ Security Considerations

• No obvious security vulnerabilities detected
• Proper error handling prevents panic propagation
• Context cancellation is properly handled
• Input validation exists for critical parameters

⚡ Performance Notes

• Generic type usage is appropriate and should provide good performance
• Concurrency handling appears well-designed with multiple backpressure strategies
• Memory usage patterns look reasonable for reactive streams

🔧 Recommendations

1. Documentation consistency: Ensure all new operators follow the excellent documentation standards in docs/CLAUDE.md
2. Error message consistency: Some error messages could benefit from consistent formatting (e.g., including function names consistently)
3. Examples: The Go playground examples mentioned in docs should be created for all new operators

📝 Breaking Changes

• No obvious breaking changes detected in the core API
• The library maintains good backward compatibility with its generic interfaces

🎯 Overall Assessment

This appears to be a well-maintained, production-ready reactive programming library for Go. The code quality is high, with good architectural patterns and comprehensive documentation.

Recommendation: ✅ Approve - This PR demonstrates good engineering practices and appears ready for merge.

The contribution guidelines in docs/docs/contributing.md are marked as "WIP" but the detailed documentation in docs/CLAUDE.md provides excellent guidance for contributors.

Great work on building a comprehensive reactive programming library for Go! 🚀
