Worked on enhancing the command-line interface experience for the thomaspoignant/go-feature-flag repository by refactoring output across multiple commands to utilize the pterm library for improved formatting and clarity. Focused on Go-based CLI development, the work introduced a standardized fatal error helper to unify error handling and reduce ambiguity in error states. These changes increased consistency and reliability across the evaluate, generate, manifest, and lint commands, streamlining troubleshooting and onboarding for new contributors. Emphasis was placed on maintainability and clear commit practices, with testing and refactoring ensuring minimal disruption while elevating the overall developer experience and usability of the CLI tools.
