Active·★ 23·MIT·Updated 2026-05-20
LangGraph-Dev-Navigator is a framework that grounds AI coding assistants in the executable truth of a specific, version-controlled codebase, reducing hallucinations and improving code reliability. It uses a local git submodule of the official LangGraph repository as ground truth, combined with a knowledge server providing Retrieval-Augmented Generation (RAG) and Knowledge Graph validation. The goal is to create a development environment where AI-generated code is more reliable and aligned with project-specific best practices.
