AI Agents for Beginners: What They Are and When to Use Them

An AI agent is a system that can plan steps, use tools, inspect results, and continue toward a goal. It is more than a single chatbot response.

Good beginner examples include research assistants, document processors, support triage tools, and code helpers that can run tests.

Agents need guardrails. They should have permissions, logs, limits, approval gates, and recovery paths when a tool fails.

The best way to learn agents is to start small: give the agent one clear task, one or two tools, and a visible timeline of what it did.
