AI agent
An AI agent is a system where a language model plans and takes actions through tools — searching, updating records, sending messages — to complete a task.

In plain words
A chatbot answers. An agent does: it breaks a goal into steps, calls tools, looks at the results and decides what to do next, looping until the task is done or it needs help. That power needs limits, approvals and logs.

Common pitfalls
- Too much autonomy too early
- Broad tools with too many permissions
- No step or cost budgets
