Worked on the zuplo/zudoku repository to enhance the reliability of the Markdown generation and cleanup workflow. Focused on preventing accidental data loss, the developer refactored the cleanup process to ensure only generated Markdown files within the dist output directory are removed, leaving source files untouched. This involved extracting a helper function to centralize output path logic and adding path traversal guards for safer file operations. By aligning the cleanup logic with the export workflow, the changes improved build stability, especially when publishing Markdown is disabled. The work was implemented using Node.js and TypeScript, demonstrating careful attention to workflow safety and maintainability.
