Worked on improving reliability and developer experience in the containers/podman-compose repository by addressing error feedback related to service configuration. Focused on enhancing the resolve_extends functionality, the developer modified error handling so that when a referenced service does not exist, the missing service name is now included in the error message. This targeted Python bug fix streamlines debugging and provides clearer feedback for users, particularly in CI/CD environments. Demonstrated strong attention to engineering discipline by delivering a minimal, well-scoped change that adheres to contribution guidelines. Utilized Python scripting, debugging, and error handling skills to improve error context and triage efficiency.
