During December 2025, this developer delivered a real-time collaboration feature for the sst/opencode repository, focusing on workspace synchronization and efficient file management. They implemented Language Server Protocol (LSP) file watch notifications using TypeScript, enabling the propagation of didChangeWatchedFiles events to all connected clients. This approach allowed workspace file changes to be detected and shared instantly, reducing the need for manual refreshes and improving collaboration workflows. By co-authoring the LSP integration, they enhanced the system’s ability to manage file changes in real time, leveraging their expertise in LSP, real-time collaboration techniques, and TypeScript to address synchronization challenges.
