Worked on the juicedata/juicefs repository to enhance documentation workflows and streamline CI/CD processes over a two-month period. Focused on upgrading markdownlint tooling and refining configuration management using YAML and JSON, the work improved contributor efficiency by reducing CI noise and clarifying documentation standards. Updated GitHub workflows to ignore non-critical changes, accelerating pull request verification and maintaining repository hygiene. Addressed a documentation bug related to the markdown-lint-fix command, ensuring guidance accurately reflected current tooling and reducing ambiguity for contributors. Emphasized maintainability and onboarding by aligning documentation with evolving linting practices, without introducing production code changes during this period.
