broken-links

Scan a codebase for broken links — dead URLs in Markdown/HTML, broken file references, invalid import paths, stale anchor links, and broken cross-doc references — then auto-fix what it can: replace dead URLs with Wayback Machine archives, update moved file paths via git history, remove anchors that no longer exist, and flag what needs human review. Self-healing: learns fix patterns and improves over iterations. Use when: 'fix broken links', 'check links', 'dead links', 'broken urls', 'link rot', 'fix references', 'validate links', 'stale links', 'broken imports'.
