Google ADK RAG Agent

Build RAG agents with Google ADK and Vertex AI RAG Engine. Sets up corpora, the VertexAiRagRetrieval tool, and citation-backed responses for document Q&A on Google Cloud.

This skill builds retrieval-augmented agents on Google's Agent Development Kit. It creates and populates Vertex AI RAG corpora, wires the VertexAiRagRetrieval tool into an ADK agent, configures the Vertex AI backend and environment, and formats citation-backed answers for document Q&A and knowledge-base search.
