During January 2026, this developer contributed to the XTLS/Xray-core repository by designing and implementing a new API method, ListRule, to enhance routing management. Using Go and gRPC, they developed an interface that allows users to retrieve and list existing routing rules, improving the usability and automation readiness of the routing service. The API was carefully aligned with existing service patterns to ensure consistency and extensibility. Their work was delivered with clear traceability through a dedicated commit and pull request, laying a foundation for future improvements in rule auditing, tooling integration, and overall routing rule management within the project.
