Worked on enhancing the tuist/tuist repository by refactoring plugin-related CLI commands to support asynchronous execution. Leveraging Swift and asynchronous programming techniques, the developer migrated PluginRunCommand and PluginTestCommand to use AsyncParsableCommand, enabling non-blocking I/O and improving the responsiveness of CLI operations. This change addressed previous blocking behavior in plugin run and test commands, resulting in faster developer feedback loops and a more scalable plugin workflow. The work laid a foundation for future extensibility of plugin commands and included collaboration on concurrency improvements and expanded test coverage, demonstrating a focus on both performance and maintainability in CLI development.
