RAG Implementation for Enterprise Knowledge

Detail the steps and provide example code for setting up the RAG system that your Mastra AI agent will use. Describe how you would ingest diverse enterprise data (e.g., HR policies, financial reports, operational manuals) into a vector database (like Pinecone or Chroma), generate embeddings, and ensure efficient retrieval. Show how the `rag_retriever` tool would interface with this vector database to fetch contextually relevant information for the agent's analysis.
