Worked on the penpot/penpot repository to address a critical crash in the Plugins API, focusing on stabilizing plugin integration and token-set management. Using Clojure and asynchronous programming techniques, resolved an asynchronous state race in the token-set proxy by implementing initial-name capture at proxy construction and introducing nil guards in addSet and removeSet functions. This approach prevented stale state reads and backend 400 errors when creating new token-sets, reducing workspace reloads and plugin disconnects. The work enhanced code resilience and hygiene, supporting smoother designer workflows and strengthening the overall plugin ecosystem within a front end development context.
