AI Agent
An AI system that can take multiple steps and use tools on its own to complete a task, rather than just answering one question at a time.
01 Definition
An AI agent doesn't just respond to a single prompt — it can break a goal into steps, decide what actions to take (like searching the web, running code, or calling an API), and keep working through a task with limited human input at each step.
02 Why It Matters
Agents are the shift from 'AI that answers questions' to 'AI that completes tasks' — understanding this term helps you evaluate tools that claim to 'automate' work versus ones that just chat.
03 Example
An AI coding agent that reads a bug report, finds the relevant file, writes a fix, and runs the tests — without being told each individual step.
