Worked on enhancing the ninech/nctl command-line interface by introducing a --verbose flag to provide users with detailed permission-denied error output and clearer help text. Focused on improving error handling by standardizing and simplifying permission-denied messages, ensuring concise user-facing feedback while propagating original errors for better troubleshooting. These updates aimed to reduce user confusion and improve the maintainability of error paths throughout the CLI. Utilized Go for implementation, applying skills in CLI development and error handling to deliver focused, high-quality commits. The work resulted in a more actionable and user-friendly experience for those interacting with the nctl tool.
