Prompt
We need to set up a multi-source RAG retrieval system for customer support documentation. Could you design a Java blueprint that merges results across multiple embedding stores, applies metadata filtering, enforces a minimum similarity threshold, and re-orders the candidate contexts before feeding them to the chat model? Include the code configuration and retrieval workflow.

RAG Implementation
Build Retrieval-Augmented Generation systems that extend AI capabilities with external knowledge sources.
Overview
This skill covers: document processing, embedding generation, vector storage, retrieval configuration, and RAG pipeline implementation.
When to Use
Building Q&A systems over proprietary documents
Creating chatbots with factual information from knowledge bases
Implementing semantic search with natural language queries
Reducing hallucinations with grounded, sourced responses
Building documentation assistants and research tools
Enabling AI systems to access domain-specific knowledge
Provides comprehensive React 19 patterns for Server Components, Server Actions, useOptimistic, useActionState, useTransition, concurrent features, Suspense boundaries, and TypeScript integration. Generates executable code patterns, validates security for public endpoints, and optimizes performance with React Compiler or manual memoization. Proactively use when building React 19 applications with Next.js App Router, implementing optimistic UI, or optimizing concurrent rendering.
