Developed a macOS disk cleanup utility for the jaywcjlove/awesome-mac repository, focusing on a command-line interface that prioritizes user safety and transparency. The tool, implemented using Markdown for documentation and open source contribution workflows, introduced a preview-first cleanup process that allows users to scan caches and development artifacts before taking action. By enabling users to select files for removal and moving them safely to Trash, the solution addressed the need for cautious disk management on macOS systems. The work emphasized clear documentation and seamless integration into the existing open source project, reflecting a methodical approach to feature delivery and user experience.
