This is the foundational skill for Andrej Karpathy's LLM Wiki pattern: a three-layer system where raw sources (docs, PDFs, images) get distilled into an Obsidian vault of interconnected markdown pages, governed by a schema that tells the LLM how to maintain it. The wiki isn't a chatbot, it's a compiled artifact. Knowledge gets synthesized once, cross-referenced with wikilinks, and kept current. You get six default categories (concepts, entities, skills, references, synthesis, journal) plus project-specific namespaces. Every page tracks provenance back to sources, and a manifest enables delta ingestion so you only process what's new. Use this when you want to understand the architecture or set up a new knowledge base. Other skills handle the actual operations like ingesting and querying.
