AI Agent

What is an AI Agent?

An AI agent is an autonomous system that goes beyond simple question-and-answer. It can plan a sequence of actions, execute them using tools (file systems, APIs, browsers, databases), evaluate results, and adjust its approach — all without human intervention at each step.

How Do AI Agents Work?

1. Goal Reception: The agent receives a high-level objective
2. Planning: It breaks the goal into subtasks and determines the order
3. Tool Use: It executes each subtask using available tools — reading files, running commands, making API calls
4. Evaluation: After each action, it checks if the result matches expectations
5. Adaptation: If something fails, it diagnoses the problem and tries a different approach

Types of AI Agents

• Coding Agents: Claude Code, Cursor — write and debug software
• Research Agents: Deep research tools that search, read, and synthesize information
• Workflow Agents: n8n AI nodes that make decisions within automated pipelines
• Customer Service Agents: Handle support tickets and route complex issues

Why AI Agents Matter

AI agents represent the next evolution beyond chatbots. While a chatbot answers one question at a time, an agent can take ownership of an entire project — building a website, running a marketing campaign, or managing a content pipeline from start to finish.

Key Takeaway: AI agents are the workforce of the future — they handle complex, multi-step work that previously required human judgment.
