Autonomous personal knowledge base agent -- builds and maintains an Obsidian-compatible wiki from raw sources. It extracts entities, concepts, and claims with strict provenance tracking, cross-references everything, and performs periodic health checks.

Configuration

Field	Value
Category	`knowledge`
Agent	`librarian`
Routing	`wiki`, `knowledge base`, `ingest source`, `ingest deep`, `deep ingest`, `crawl`, `wiki query`, `wiki lint`

Integrations

Git -- Required for version control. Every operation (ingest, query, lint, maintain) is automatically committed to your vault history.
qmd -- (Optional) A local hybrid search engine. Recommended for wikis scaling beyond 200 pages.

Settings

Wiki Vault Path -- Directory where your wiki files will be stored (default: ./wiki)
File-Back Mode -- How to handle saving generated syntheses (auto, ask, never)
Search Backend -- The search engine to use for queries (index, qmd)
Wiki Content Language -- Target language for all generated content in the wiki (default: en)

Features

Ingestion: Give the agent raw sources (markdown, text, HTML, PDF via terminal) and it will extract factual claims, identify entities, and build connected concept pages.
Deep Ingestion (ingest-deep): Provide a starting URL, and the agent will intelligently crawl the main page along with up to 5 of its most substantive sub-pages to build a comprehensive knowledge tree in one go.
Synthesized Queries: Ask questions across your entire knowledge base. The agent provides answers backed by [[wikilink]] citations, effectively compiling its response from your collected literature.
Linting & Maintenance: The agent can periodically scan the wiki to merge duplicate entities, fix broken links, identify contradictions, and point out orphan pages.
