What Is an AI Agent? Systems That Take Actions
DICTIONARY · AI

What Is an AI Agent?

An AI agent is a system that pursues a goal across several steps, using tools and taking actions rather than only producing an answer.

In plain English

Answering is one step and one failure mode. Acting is many steps, where each error compounds into the next, which is why agents are dramatically harder to make reliable than assistants.

The agents that work today are narrow: a defined task, a small set of tools, a clear stopping condition, and a human checking the result.

What to know

Goal-directed
Given an objective, it plans and executes steps towards it.
Uses tools
Searching, calling APIs, reading files, writing to systems.
Compounding error
A wrong step early produces confident nonsense later.
Needs boundaries
Permissions, spend limits, step limits and a human review point.

Why it matters

Agents are where most of the current AI ambition sits and where most of the current disappointment comes from. Narrow, permissioned, reviewable agents deliver; open-ended autonomous ones mostly demonstrate.

Common mistakes

×Giving an agent broad permissions on live systems.
×No step limit, so a loop runs expensively.
×No logging, so failures cannot be diagnosed.
×Automating a process that was never documented or reliable manually.

FAQs

Are agents ready for production?

Narrow ones with human review, yes. Open-ended autonomy, not yet.

What is the biggest risk?

Compounding errors executed with real permissions on real systems.
