Managing prompts in large language model (LLM) applications, particularly those using retrieval-augmented generation (RAG), presents a significant challenge. The prompt sent to the model is often a complex assembly of various components, including system templates, retrieved data, tool schemas, conversation history, and few-shot examples. These components can change independently and at different cadences, making it difficult to track what exactly influences model behavior and to diagnose issues when quality degrades. The author proposes a solution involving comprehensive fingerprinting of all inputs that affect model output, logging these fingerprints with every trace, and implementing a small assembler that tracks provenance and eviction priority for each prompt component.
