LlamaIndex's legal-kb is an open-source reference application that gives AI agents file-system-like operations on Index v2 document knowledge bases. It exposes four tools: retrieve (hybrid semantic search), find, read, and grep, with automatic version control and visual citations. The tech stack includes TanStack Start, AI SDK 6 (with ToolLoopAgent), Prisma, and WorkOS. For developers building enterprise RAG or document analysis apps with LlamaIndex, legal-kb provides a ready-to-use pattern—encapsulating retrieval logic into callable agent tools with built-in versioning and citations. This eliminates the need to design tool interfaces and state management from scratch, accelerating integration of document knowledge bases into agent workflows.
