Claude Architecture Variants Overview Five architecture patterns for Claude-powered applications: Chatbot (stateless API wrapper), RAG (retrieval-augmented generation with vector search), Agent (tool use loop), Content Pipeline (batch processing), and Evaluation (using Claude as a judge). Each includes complete code and a comparison table. 1. Chatbot (Stateless API Wrapper) Simplest pattern — proxy Claude with a system prompt. Best for: Customer support, Q&A, simple conversational interfaces. 2. RAG (Retrieval-Augmented Generation) Fetch relevant context, inject into prompt, generate grounded…
