Worked on the brevdev/brev-cli repository to enhance the authentication experience by addressing a bug that caused duplicate interactive login prompts. The solution involved implementing a pre-check for access tokens before executing authenticated commands, ensuring that users were only prompted to log in when necessary. This approach streamlined the CLI authentication flow, reducing unnecessary interruptions and lowering support overhead. The work required backend development and error handling skills, with a focus on API integration using Go. By consolidating the fix into a single, well-documented commit, the developer demonstrated effective bug triage and a targeted approach to improving user experience.
