Real AI Agent or Just a Wrapper? Three Questions

BasicsAI agentsClaude

Three questions. Does it have instructions that live somewhere, not just a prompt you typed once? Does it have tools that do something beyond generating text? Does something start it without a person asking, every time? All three means agent. Missing one means a wrapper around a model.

This is the version to run before you sign anything, and it takes under a minute.

Why this matters commercially

The gap between a wrapper and an agent is not a technical nicety. It is what you are paying for.

A wrapper is a good prompt with an interface on top. It can be genuinely useful, quick to build, and worth money. What it cannot do is run without you, which is the thing agent pricing is usually justified by. Buying one while being told you bought the other is how a tool ends up abandoned three weeks in.

Calling it a wrapper is not an insult

Most of what is on the market right now is a prompt with a nice interface. No standing instructions, no real tools, no trigger. That is not a failure. It is a different thing, and it deserves a different word.

If you cannot point to all three, say "wrapper" and move on. Accurate language here is how you avoid paying agent prices for prompt value, and it makes the conversation with a vendor much shorter.

How can I tell if something is a real AI agent or just a wrapper?

Ask three questions. Does it have instructions stored with it rather than a prompt you retype? Does it have tools that act on real systems rather than only generating text? Does something trigger it without a person asking? All three means agent; missing one means a wrapper around a model.

Is a wrapper around an AI model useless?

No. A wrapper can be genuinely useful and worth paying for. It just cannot run without you, which is the capability agent pricing is usually justified by.

What questions should I ask an AI vendor?

Ask where the instructions live, which systems the tools can touch and change, and what triggers it without a person. Vague answers to those three are the answer.

Why do so many products call themselves agents?

Because the word sells. Most of what is labelled an agent today is a prompt with a good interface, which is a different product with a different price.
