Over a two-month period, contributed to RSSNext/Folo and DIYgod/RSSHub by delivering targeted improvements in documentation and workflow automation. For RSSNext/Folo, performed a focused cleanup of the README using Markdown, removing outdated sections to streamline onboarding and reduce user confusion. In DIYgod/RSSHub, overhauled the GitHub Container Registry cleanup workflow, implementing daily retention policies, PAT-based authentication, and enhanced logging for better observability and reliability. Leveraged skills in Shell scripting, GitHub Actions, and jq to optimize workflow performance, introduce parallel processing, and strengthen error handling, resulting in more maintainable automation and clearer documentation for both repositories without introducing new bugs.
