Key points

  • GKG builds a structured knowledge graph from code AST for precise queries.
  • RAG relies on vector similarity, good for natural language but not code relationships.
  • Evaluation on 79 real MRs shows GKG improves coverage and precision.
  • GKG integration runs as a sidecar service in CI pipeline.
