Worked on enhancing data validation and type safety within the SmartBear/smartbear-mcp repository by introducing a new data validation layer using Zod. This feature established schema-based validation throughout the application, ensuring improved data integrity and reducing the risk of runtime errors. The approach involved integrating Zod as a dependency and leveraging TypeScript’s type system to enforce stricter data contracts. By focusing on dependency management and robust type checking, the work positioned the codebase for safer future development and increased developer productivity. The changes laid a foundation for more reliable data handling and maintainable code in the TypeScript ecosystem.
