RAG plus agent capabilities
Retrieval is one layer of the context.
RAGFlow is an open-source retrieval-augmented generation engine that fuses RAG with agent capabilities to create a context layer for LLMs. The word layer matters, because retrieved chunks are one input among several.

Proportions are illustrative. The project describes fusing RAG with agent capabilities to create a context layer for LLMs.
Retrieval
Chunks still matter
Getting the right passage is the part everyone built first, and it stays load-bearing.
Agent
Some context is produced
A tool call generates context that no document contained, which is a different source with different failure modes.
Layer
One place to assemble it
Naming it a layer says the assembly is a component you can inspect rather than prompt code scattered across an app.
