Worked on the charmbracelet/crush repository to enhance UI quality and stability by addressing a specific issue with duplicate rendering of custom skills. Using Go and UI development expertise, implemented a targeted fix that corrected the handling of the stateNames map to prevent duplicate entries from appearing in the user interface. This change improved data integrity and reduced user confusion by ensuring that each custom skill was displayed only once. The solution was delivered as a focused, single-commit update with minimal risk, providing a clear path for reversion if needed. The work emphasized careful debugging and precise state management within the codebase.
