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.

Before You Start

Resolve config — follow the Config Resolution Protocol in llm-wiki/SKILL.md (inline @name override → walk up CWD for .env → ~/.obsidian-wiki/config → prompt setup). This gives OBSIDIAN_VAULT_PATH and OBSIDIAN_LINK_FORMAT (default: wikilink).

Read index.md to get the full inventory of pages and their one-line descriptions

Skim log.md to see what was recently ingested (focus linking effort on new pages)

When inserting links in Step 4, apply the link format from llm-wiki/SKILL.md (Link Format section) using the OBSIDIAN_LINK_FORMAT value. When OBSIDIAN_LINK_FORMAT=markdown, compute the relative .md path from the file being edited to the target page.

Step 1: Build the Page Registry

Glob all .md files in the vault (excluding _archives/, .obsidian/). For each page, extract:
