FeatLens: Feature-Guided Code Graph Retrieval for Repo-Level Code Generation
The key shift is replacing expensive persistent repository graphs and LLM-based exploration with a deterministic, feature-indexed retrieval pipeline, making repo-level context cheap enough for routine use. Teams building coding assistants or agent frameworks can adopt the approach to cut context costs without sacrificing dependency recall. For cost-sensitive deployments, pairing it with DeepSeek-V3.2 gives near-identical DIR@1 to GPT-5-mini at lower inference cost.
