Developed a real-time AI Thinking Time Timer feature for the chatboxai/chatbox repository, focusing on enhancing user experience by providing immediate feedback on AI processing duration during streaming responses. The work involved creating a reusable useThinkingTimer hook in React, centralizing timing logic for thinking blocks and integrating it into the user interface. This addition enabled users to see elapsed processing time, supporting latency benchmarking and improving interaction flow. The implementation adhered to repository conventions and included thorough commit messaging. The project utilized TypeScript and JavaScript for frontend development, with an emphasis on state management and maintainable, component-driven architecture.
