In July 2025, Shtekel focused on enhancing the stability of the wix-incubator/repluggable repository by developing a verification mechanism for AppHost entry points. He addressed the risk of runtime errors caused by unavailable APIs by introducing a new AppHost interface method and its implementation, enabling pre-runtime checks for API readiness. Using TypeScript and JavaScript, he designed and tested this feature to ensure that entry points do not proceed when dependent APIs are missing, thereby supporting safer API boundary evolution. The work demonstrated depth in API design and error handling, contributing to more reliable deployments and clearer diagnostics for the project.
