Worked on the modelcontextprotocol/typescript-sdk repository to enhance the stability and reliability of event parsing within a TypeScript SDK. Focused on disciplined dependency management, the developer identified and resolved a critical import and runtime error by adding the missing eventsource-parser dependency. This targeted fix ensured that event handling remained functional in production environments, directly reducing the risk of downtime for downstream consumers. The work involved validating both build and runtime behavior after the change, demonstrating a methodical approach to quality assurance. Leveraged TypeScript and dependency management best practices to deliver a focused, traceable improvement that stabilized event processing workflows.
