Backrefs is a tool that helps you keep track of cross-references in your plain text files, like when you’re writing documentation or notes in Markdown. It scans your documents for links to other sections, figures, or data and alerts you if those references break after edits. I use it to avoid dead links in my project wikis and personal knowledge base, saving time that would otherwise go to manual checks.
