Worked on maintenance and improvement of Homebrew Cask management and documentation across the lizongying/homebrew-cask and RSSNext/Folo repositories. Focused on reducing technical debt by removing the discontinued folo@nightly cask, which helped prevent outdated installations and streamlined ongoing maintenance. Addressed onboarding issues by correcting the Homebrew Cask installation URL in the RSSNext/Folo README, ensuring macOS users received accurate installation guidance. Employed Ruby for cask management and Markdown for documentation updates, maintaining consistency across both repositories. The work emphasized risk reduction and user experience improvements through careful deprecation, cross-repo alignment, and clear, up-to-date documentation for end users and maintainers.
