│ Agent: Expert Researcher │
│ │
│ Final Answer: │
│ An AI agent is an intelligent system designed to achieve specific goals by perceiving its environment and │
│ taking independent actions. Unlike a standard chatbot that only provides information, an agent can use │
│ external tools and create complex plans to complete tasks autonomously. Essentially, it moves beyond just │
│ talking to actually doing work on your behalf. │
