Worked on the mozilla/gecko-dev repository to streamline command-line interface usage by removing the unused --push-to-lando flag from the mach try command. This change consolidated the default behavior to always push to Lando, eliminating redundant options and related warnings. The approach focused on code refactoring and build tool maintenance, using Python to simplify the CLI surface area and reduce potential confusion for developers. By aligning the tooling with established defaults, the update improved developer productivity and reduced support overhead. The work demonstrated attention to detail in command-line interface design and contributed to a cleaner, more maintainable development workflow.
