Worked on backend reliability for the google/adk-go repository, focusing on improving terminal output rendering in non-TTY environments. Addressed a bug by replacing x/term with standard library TTY detection, ensuring output adapts correctly to both interactive and automated contexts such as CI pipelines. Refactored streaming mode resolution to occur outside the user loop, enhancing correctness and performance. Cleaned up Go module dependencies and updated go.sum to support reproducible builds. The work was delivered as a single, well-documented commit with clear rationale and test coverage considerations, demonstrating proficiency in Go and backend development with attention to maintainability and deployment consistency.
