During February 2026, Li worked on the justlovemaki/AIClient-2-API repository, focusing on stability and performance improvements in the user interface and session management. Addressing issues in the Plugin List UI, Li resolved duplicate card rendering by ensuring the container was cleared before new content was added, which reduced UI flicker and improved responsiveness. Additionally, Li optimized session cache reuse by refining cache key logic, removing unnecessary model prefixes to minimize cache misses when switching models within a session. Leveraging JavaScript and applying both frontend and backend development skills, Li delivered targeted bug fixes that enhanced the reliability of the application.
