Worked on the obra/superpowers repository to enhance repository hygiene by ensuring macOS .DS_Store files are ignored, preventing unnecessary metadata from being tracked in version control. Applied Git best practices to update the .gitignore file, which keeps the codebase focused on source files and reduces noise in pull requests and diffs. This change streamlines code reviews and helps maintain a clean project history, benefiting both current and future contributors. Demonstrated disciplined repository maintenance and cross-operating system awareness, using Git and text-based configuration to address common metadata issues and improve the onboarding experience for developers working across different environments.
