What is AI Agent?
An AI system that can autonomously plan, execute tasks, and use tools to achieve goals.
Definition
An AI agent is a system that goes beyond simple question-answering to autonomously plan multi-step workflows, make decisions, use external tools (APIs, databases, web browsers), and iterate on results. Agents can break complex tasks into subtasks, execute them in sequence, and adapt their approach based on intermediate results.
💡 Example
Claude Code acts as an AI agent — you describe what you want to build, and it autonomously plans the implementation, writes code across multiple files, runs tests, debugs errors, and iterates until the task is complete.
