What is an agent?

Imagine a really good helper. You tell it what you want, and it figures out the steps by itself. That's an agent. It does three things, over and over: look, think, do.

1. It looks πŸ‘€

First the agent looks at what's around β€” a message from you, a page on a website, a photo. Looking is how it figures out what's going on right now.

2. It thinks πŸ€”

Then it thinks: "What should I do about this?" It makes a little plan. If the plan needs more information, it goes back and looks again.

3. It does πŸ–οΈ

Finally it does something β€” sends a reply, saves a note, gives you a price. Then it looks again to see if that worked. Look, think, do. That loop is the whole trick.
