Feature Description
Explanation of Workflow
Trigger: The workflow runs every time a new issue is created.
Check Duplicates: Uses a GitHub Action to detect similar issues by comparing the title and content with keywords and common phrases.
Close and Comment: If a duplicate is detected, it closes the issue and comments on it, linking to the original issue.

Use Case
This duplicate detection workflow significantly streamlines project management by automatically reducing redundant issues, helping maintainers focus on unique, unresolved problems. It saves time by automating the identification and closure of similar issues, preventing contributors from repeatedly addressing the same questions or bugs. With a clear link to the original issue, users can easily follow updates, improving transparency and reducing confusion. The feature enhances productivity by keeping the issue list organized, ensuring that attention goes to high-priority or novel issues. Overall, it fosters a more efficient, user-friendly environment, promoting collaboration and faster resolution of project needs.
