Worked on the ChromeDevTools/chrome-devtools-mcp repository to enhance lifecycle management of the Chrome subprocess, focusing on reliable and consistent shutdown behavior. Developed a graceful shutdown path that handles stdin EOF and termination signals, ensuring the Chrome subprocess exits cleanly under various scenarios. Leveraged Node.js and TypeScript to implement robust shutdown handlers and a safety timeout, aligning teardown logic with existing watchdog and daemon patterns for cross-component consistency. This backend development improved server reliability, reduced manual intervention, and stabilized CI/CD workflows by guaranteeing deterministic and fast shutdowns, ultimately optimizing resource utilization and enhancing the overall developer experience within the project.
