During July 2025, Mavc focused on enhancing code quality and maintainability across the facebook/dotslash, facebook/pyrefly, and facebook/relay repositories. They integrated the ruff_python_formatter into both dotslash and pyrefly, enabling automated Python code formatting for XStream pipeline outputs and ensuring consistent conversion of Python ASTs to text. In relay, Mavc improved Rust dependency management by updating the dunce library in Cargo.toml, which increased compatibility with the new formatting tools. Their work combined Python and Rust development with a focus on code formatting, dependency management, and cross-repository library integration, resulting in more reliable and maintainable pipeline infrastructure.
