code-graph-rag

What it does

Parses a multi-language codebase with Tree-sitter, builds a structural knowledge graph in Memgraph, and answers questions by traversing it — which returns accurate results on large repositories where keyword search flails. Editing and optimisation flow through the same graph. It needs a graph database standing by, making it heavier to set up than the fully local alternatives, and indexing cost scales with repository size. MIT.
