Worked on the Lilypad-Tech/lilypad repository to enhance the command-line interface by refining error handling during option processing. Focused on suppressing default usage text when errors occurred, this change reduced unnecessary output and made actual error messages more visible to users. The solution involved updating multiple Go source files, including mediator.go and run.go, to ensure consistent behavior across several CLI commands. Leveraging skills in CLI development and error handling, the work consolidated error output logic into a single, maintainable fix. This improvement streamlined the user experience and simplified troubleshooting by presenting a cleaner, more focused error surface during CLI interactions.
