America Law Graph

edgardomunoznajar/oblique-lawyer

This connects Claude to a 529,000 section corpus covering all 50 US state codes, the United States Code, and the Code of Federal Regulations. You get semantic search across the entire corpus plus a citation graph showing how statutes reference each other. Reach for this when you need to research legal questions, trace statutory authority, or build tools that work with US law at scale. The semantic search means you can query by concept rather than exact keywords, and the citation graph lets you map relationships between federal and state law provisions.
