AI Agent

Applications
Simple Definition

An AI system that can autonomously take actions, use tools, and complete multi-step tasks without human intervention at each step.

Full Explanation

Unlike a chatbot that answers questions, an AI agent plans and executes sequences of actions to achieve a goal. It uses tools (web search, code execution, file access, APIs) and makes decisions about what to do next based on results. Examples: Claude Code (writes and runs code autonomously), Devin (autonomous software engineer), AI agents that manage email workflows.

Example

Claude Code is an AI agent that can read your codebase, write code, run tests, and fix errors autonomously.
