- In short
- The five documented reference architectures are: agent (an open-ended loop where Claude decides its own next step until a stop condition), RAG (retrieval augments a call with chunks from a stable corpus), document-processing pipeline with an evaluator-optimizer pass (process items, then check against a rubric and refine), routing (an initial classification sends work down a specialised path), and coding agent (agentic exploration paired with deterministic edit, test, and review steps). Each is a shape to adapt, not a blueprint to copy.
