During February 2025, Sugawara developed a new WithStatusCheck option for the DataDog/dd-trace-go repository, focusing on enhancing HTTP error reporting for services using Gorilla Mux. By integrating this feature in Go, Sugawara enabled developers to specify which HTTP status codes should be classified as errors within traces, allowing for more granular and meaningful error classification. The implementation involved targeted API integration and thorough testing, resulting in a single, focused commit that improved observability and triage efficiency. This work addressed the challenge of reducing noise in error signals, ultimately supporting faster and more accurate incident response for teams leveraging dd-trace-go.
