feat: add /understand-knowledge for Karpathy LLM wiki knowledge bases
Support the Karpathy LLM wiki pattern — a three-layer architecture
(raw sources + wiki markdown + schema) with wikilinks, index.md
categories, and append-only log.md.
Pipeline:
- parse-knowledge-base.py: deterministic extraction of articles,
wikilinks, categories from index.md, source nodes from raw/
- article-analyzer agent: LLM-based entity/claim extraction and
implicit relationship discovery (builds_on, contradicts, etc.)
- merge-knowledge-graph.py: combines scan + analysis with entity
dedup, layer assignment from categories, tour generation
Dashboard:
- KnowledgeGraphView with d3-force layout (community clustering
by index.md categories, degree-proportional sizing)
- 5 knowledge node types (article, entity, topic, claim, source)
- 6 knowledge edge types with visual styling
- KnowledgeNodeDetails sidebar (wikilinks, backlinks, preview)
- Auto-detect kind:"knowledge" → knowledge-only view mode
Core:
- 5 node types + 6 edge types added to NodeType/EdgeType unions
- KnowledgeMeta interface (wikilinks, backlinks, category, content)
- kind field on KnowledgeGraph for view mode detection
- Zod schemas + node/edge type aliases
