What is an AI agent? An assistant with permission to act

Try this first: ask for a suggestion, not an action

You have a to-do list, a few unanswered messages and a meeting to prepare for. Ask AI to suggest the order in which to handle them. You get an order and reasons right away, but nothing changes in your calendar or inbox. A suggestion is not permission to act. This exercise shows the difference between a chat and an agent faster than a definition.

A regular AI chat responds and makes suggestions in text. An AI agent can also use connected tools, such as searching for information or drafting a message, but only with limited permissions and agreed rules.

Access to a tool alone does not make an assistant an agent; what matters is how it uses that access. When a regular assistant searches once, it shows you the result and waits. An agent can search, inspect the result, decide what to do next and continue through several rounds without you starting each step. This repeated cycle—act, observe what happened, decide the next step—is what makes an assistant an agent.

Three things to keep separate

1. Suggestion: the agent says what it recommends or drafts something. Nothing in the system changes.
2. Permission to act: the agent may use a specific tool for a limited purpose, such as creating a draft or adding a task to a list.
3. Human approval: a person reviews and approves before a message is sent, payment is made, content is published, data is changed or another significant action takes place.

Try an agent for the first time

1. 1

   Choose a task that only needs a suggestion

   For example, start by organizing your weekly task list or drafting a meeting agenda. Do not start with sending emails or making purchases.

2. 2

   Set a goal and a boundary

   Tell the agent what it may and may not do. For example: draft something, but do not change my calendar or send anything.

3. 3

   Review the suggestion

   Read the list, assumptions and possible errors. An agent can make a plausible but incorrect interpretation of your task.

4. 4

   Grant permission to act only later

   If the service can connect to your calendar or messages, first try it with a test account or a reversible change. Approve every message or change yourself.

Try out a suggestion and an approval boundary

Put these fictional tasks in priority order: reply to two messages, prepare for a 30-minute meeting and make a shopping list. Explain your reasons, but do not change my calendar, messages or any other service.

Preparing for the meeting will take an hour after all. Reorder the list based on this information. Still do not change my calendar or messages.

Draft a friendly reminder for a fictional association. Do not send it. Mark the parts I need to review and approve before it is sent.

Make the boundary precise

Suggest three possible 30-minute times next week and draft an invitation. Do not read anyone else’s calendar, send the invitation or make changes unless I approve the time and wording separately.

Keep permissions limited

• Ask the service for a log of the tools the agent used and the actions it took, so you can check afterward what it actually did.

Once you know the basics

Once a small workflow works reliably, write down what the agent may read, suggest and do, and where a person must approve. Also test an error case: what happens if information is missing or the request is unclear?
