Steven Chen focused on streamlining the SDK API surface for the ViveportSoftware/pc-lib repository during January 2025. He removed obsolete ILocalPlayerEvents interfaces from the create-sdk-ts project, targeting event definitions related to player avatar movement, running, and flying. This cleanup, implemented in TypeScript, reduced the SDK’s maintenance burden and simplified the event model for downstream integrations. By eliminating unused interfaces, Steven improved the stability and clarity of the SDK, making onboarding easier for developers. His work demonstrated a methodical approach to SDK development, emphasizing maintainability and clarity over breadth, and addressed technical debt within the TypeScript codebase.
