# Wiki extract — index

**Vault extractors** live as separate **`wiki-extract-*`** skills (frontmatter for discovery) plus matching **`skills/references/wiki-extract-*.md`** files (full procedures, commands, troubleshooting).

**Prefer orchestration skills first:** **wiki-research** and **wiki-research-web** already route URLs and intents to the right extractor. Use this index when you need the routing table without opening the research skills.
