Each component has its own responsibilities and evaluation focus: the prompt template handles version management of instructions, examples and context assembly; document ingestion and retrieval maintain source versions, access filtering, indexes and excerpts; tool execution obtains authoritative values and performs authorized operations; deterministic application logic enforces explicit business rules and output constraints; training and model registration track datasets, base versions, fine-tuned artifacts and evaluation evidence; orchestration and monitoring assemble context, route requests and record diagnostic information.
