An AI agent is a system that can work through steps towards a goal, often using tools. A chatbot may tell you how to organise a report. An agent with suitable access may also read documents, prepare a file or perform an action. What it can do depends on the product, permissions and setup.
Updated 5 October 2026. This guide uses illustrative workflows. It does not claim an agent completed the examples or that any tool can safely act without oversight.
Chat, automation and agents
A chat answer gives you information. A fixed automation follows predefined rules. An agent may choose intermediate steps based on instructions and what happens along the way. Real products can combine all three approaches. The label alone does not tell you how reliable a system is.
Example: preparing a weekly report
Imagine a system that reads approved notes, groups completed work, drafts an update and asks for approval. That is different from a system allowed to email the report automatically. Both may be described as agents, but the second has a more consequential final step.
| Step | Failure to watch for | Control |
|---|---|---|
| Read notes | Missing or outdated information | Use an approved source folder |
| Summarise | Invented progress or dates | Require source references |
| Prepare report | Wrong format or omitted blocker | Review against a checklist |
| Send | Wrong recipient or unapproved promise | Keep human approval |
Start with a read-only task
Choose public or made-up information. Ask the system to explain its proposed steps. Do not give it permissions to buy, delete or send while testing. Check the result before connecting real business accounts.
Write a clear task boundary
Prepare a draft update from the supplied notes. Do not send it. Use only the approved sources. Flag missing information. Stop and ask for review if a source is unavailable or contradictory.
Then test a failure deliberately: leave out a deadline or add two conflicting figures. A useful system should surface the problem instead of producing a confident guess.
Questions before connecting a tool
- What can it read and change?
- Can it act without approval?
- Where is information stored?
- Can you see what it did?
- How do you stop or reverse an incorrect action?
Access should match the task. A report assistant does not automatically need permission to manage payments or delete records.
When a simpler process is better
If the task is rare or the instructions are unclear, manual work may be easier to check. A fixed checklist may be enough for a predictable process. Do not add an agent just because a demo makes a complex workflow look effortless.
