Structure and Role of System Prompts in Defining AI Model Behavior and Boundaries

System Prompt is a high-level instruction layer executed before the user inputs a message, defining the AI model's role, tone, knowledge scope, tool calling methods, and guardrails. Developers use this to control the AI model to behave consistently across all customer interactions.

System prompts have higher priority than user prompts and determine the fundamental behavior of the conversation. The key components are as follows:

• Role: The specific identity the model should emulate or perform
• Environment: The context in which the AI assists and the scope of accessible data
• Tone: Guidelines for the tone and language use of responses
• Goal: The core purpose for resolving conversations and enhancing customer experience
• Guardrails: Rules for prohibited topics, protection of sensitive information, and handling manipulation attempts
• Process and Format: Response structure, when to ask clarifying questions, and connectable tools and data sources

Using clear Markdown section boundaries prevents 'instruction bleed' where instructions interfere with each other and helps the model process information according to priority.
