Worked on expanding Claude model support and stabilizing runtime behavior in the angular/web-codegen-scorer repository, delivering new capabilities for code generation runners. Integrated Claude 4.6 Opus and additional Claude model versions, unifying model compatibility across runners and improving reliability. Addressed a TypeError related to illegal constructor usage, enhancing runtime stability and user-facing reliability. In the nrwl/nx repository, normalized the HMR option for the Angular dev server, ensuring consistent behavior across Angular versions and aligning with Angular 19 defaults. Leveraged TypeScript, Node.js, and Angular to improve cross-version compatibility, streamline development workflows, and reduce maintenance overhead for both codebases.
