Over a two-month period, Moluopro contributed to the dart-lang/sdk and V-Sekai/godot repositories, focusing on benchmarking accuracy, documentation clarity, and system reliability. In dart-lang/sdk, Moluopro refactored the benchmark module to use microseconds instead of milliseconds, ensuring precise performance scoring, and enhanced SDK documentation with updated links and architecture-specific build guidance using Markdown and YAML. For V-Sekai/godot, Moluopro improved disk space reporting on Windows by adjusting the get_space_left function to reference the current directory, addressing platform-specific correctness. Across both projects, Moluopro applied C++ and documentation management skills, delivering targeted improvements that reduced onboarding friction and increased operational accuracy.
