Worked on the oh-my-codex repository to improve the reliability of its CLI watcher shutdown process. Addressed a specific issue where ESRCH errors would generate unnecessary log noise during the teardown of notify fallback watchers. By refining error handling in the TypeScript codebase, the update ensures that stale ESRCH errors are safely ignored, resulting in cleaner logs and a smoother user experience. The patch was minimal in scope, focusing on CLI development and robust error management without introducing new features. This targeted fix contributed to greater product stability and more predictable CLI behavior, supporting ongoing reliability improvements for the notify subsystem.
