Most RAG failures don’t crash. They silently return bad answers. I built a repair layer for that.
Short summary
RAG systems often fail silently, returning wrong answers with no clear diagnosis of the underlying cause. ragbolt is a lightweight repair layer that detects whether failures originate from retrieval, generation, or grounding, applies bounded repairs, re-verifies results, and emits full execution traces. It integrates with LangChain and LlamaIndex.
