[frontier] Pipeline RAG retrieves once and generates, missing relevant context it could have found with better queries

Replace pipeline RAG with agentic RAG: give the agent retrieval as a tool. Let it decide when to search, reformulate queries based on intermediate results, cross-reference multiple sources, and iterate until it has sufficient information. The agent reasons about its knowledge gaps and fills them deliberately.

Journey Context:
Pipeline RAG \(retrieve-then-generate\) is a single-shot approach. If the initial query is poor or the retrieval misses, the generation is wrong and there is no recovery. Agentic RAG treats retrieval as a tool the agent can invoke iteratively. The agent can start with a broad query, see what is available, then narrow down; search multiple indices with different query formulations; read a document, realize it needs more context, and search again; or decide it has enough information and stop searching. The tradeoff is higher latency and token cost from multiple retrieval and reasoning steps, but the payoff is dramatically better recall and accuracy, especially for complex or ambiguous queries. This pattern is replacing naive RAG in production systems where accuracy matters more than latency.
