AI Agent

An AI agent is an AI system that goes beyond simple question-and-answer interactions. It can make decisions, use tools (like searching the web, running code, or accessing databases), maintain memory across interactions, and work toward goals with minimal human intervention. Think of it as the difference between asking someone a question (a chatbot) and hiring someone to do a job (an agent).

A customer support agent doesn't just answer questions — it looks up order information, processes refunds, escalates issues, and follows company policies. Building effective AI agents requires well-crafted system prompts that define the agent's role, available tools, decision-making rules, and boundaries.
