Isabelle Duffner developed context usage visualization enhancements for the SEMOSS/semoss-ui repository, focusing on improving how operators interpret and manage token usage data. She implemented a pie chart to display context usage, a high-usage indicator, and an interactive token usage visualization with a details dropdown, all designed to make usage patterns more accessible. Using React and TypeScript, Isabelle standardized token value formatting across visualizations to ensure consistency and reduce interpretation risk. Her work emphasized front-end data visualization and interactive UI components, enabling users to quickly identify trends, optimize resource allocation, and make more informed, data-driven decisions within the application.
