LlamaIndex ships legal-kb as an agentic retrieval reference app

MarkTechPost reports that LlamaIndex has published legal-kb, a public GitHub reference application for legal-document knowledge bases. The app uses LlamaIndex Index v2 and gives an agent filesystem-style tools for hybrid retrieval, file search, reading, and grep, rather than relying on one vector search per question. The reference stack also shows visual citations, project-level file versioning, background indexing, and bring-your-own OpenAI or Anthropic keys through a TanStack Start app.

Key details: legal-kb is a public reference application built on LlamaIndex Index v2, The agent uses retrieve, findFiles, readFile, and grepFile tools, The workflow supports versioned documents, background indexing, and visual citations.

Why it matters: It is a concrete enterprise pattern for document agents that need to inspect, cite, and verify long files instead of returning a single RAG snippet.
