Designing for the inevitable: System prompt leakage and mitigations in generative AI applications

System prompts form the foundation of generative AI applications. A system prompt is a collection of instructions and operational context provided to a large language model (LLM) that shapes how the model behaves and interacts with users and tools. System prompts often contain proprietary information, including role definitions, behavioral guidelines, tool descriptions and usage instructions, placeholders for conversation history and user metadata, Retrieval-Augmented…
