### Answer --- The Global Prompt in Retell AI is where you specify the agent's persona, identity, guardrails, etc. [(1) ]() This text is available in every node and influences all response generation. ## Best Practices For Single/Multi-Prompt Agents: - The

general_prompt

is appended to the system prompt regardless of what state the agent is in. [(2) ]() - System prompt (with state) = general prompt + state prompt. - System prompt (no state) = general prompt. For Conversation Flow Agents: - The

global_prompt

is used in every node of the conversation flow. [(3) ]() - Node Prompts take precedence over the Global Prompt when both are present. [(4) ]() - Use the Global Prompt for tone, identity, and general rules. - Use Node Prompts for specific actions or logic per step. - Avoid duplication—Global = default, Node = override. For Flex Mode: - Write node instructions in a concise manner so the LLM can better focus on the task. [(5) ]() - Be explicit on transitions: write crisp, observable conditions. - If using flex mode for more than 20 nodes, performance might degrade and the agent might have higher hallucination risk—consider splitting into smaller components.
