What Cross-Linker does

Cross-Linker scans an Obsidian wiki and automatically discovers missing cross-references between pages, then inserts [[wikilinks]] to connect them. Use it after large ingestions or when pages feel disconnected to weave new content into the knowledge graph.

Cross-Linker is cataloged under Automation on DirSkills. Cross-Linker comes from a repository tagged agent-skills, brain, knowledge-base, llm-tools and obsidian.

README

Excerpt

Cross-Linker — Automated Wiki Cross-Referencing

You are weaving the wiki's knowledge graph tighter by finding and inserting missing [[wikilinks]] between pages that should reference each other but currently don't.

Follow the Retrieval Primitives table in llm-wiki/SKILL.md. Build the registry in Step 1 by grepping frontmatter only (not full pages). Reserve full Read for the unlinked-mention detection pass, and even there, only read pages whose summaries/titles make them plausible link targets. Blind full-vault reads are what this framework exists to avoid.
