Cole Medin demonstrates a comprehensive AI agent system using a free n8n workflow template. The blueprint divides the agent into 7 key nodes—LLM, tool, control, memory, guardrail, fallback, and user input—arranged as an interdependent graph. This system handles dynamic reasoning, error fallback, and human-in-loop approvals, while integrating external services like BrightData and AirTable for real-time data access. It offers a robust, modular approach to automating complex AI tasks.
