A Look at Agents · Lesson 1 of 3

What an agent actually is

"AI agents" is the loudest phrase in tech right now. Here's what it actually means, minus the hype, and why you're better prepared for it than most.

Chat answers. An agent works.

Everything so far in this course has been a conversation: you send a message, Claude answers, you send the next one. You drive every step.

An agent is the same intelligence given a goal instead of a message. It plans the steps itself, does them, checks its own work, and comes back when it's finished or stuck. Reading files, searching the web, filling a spreadsheet, drafting a batch of documents: multi-step work, done while you do something else.

Concrete version. Chat: "summarize this POS system contract." Agent: "compare the three POS systems I'm considering, check current pricing and real user complaints, and give me a table with a recommendation." The second one is ten steps, and the agent takes all ten.

The honest part

An agent makes the same kinds of mistakes Claude makes in chat. It just makes them faster, in bulk, and while you're not watching. Confident guessing at step 3 flows into steps 4 through 10. That's not a reason to avoid agents. It's the reason your course habits matter more here, not less: verify what matters, blanks beat guesses, and nothing goes out with your name on it unread.

The other skill that matters more: the briefing. A vague goal sends an agent off doing vague work at high speed. You already know how to fix that, because it's lesson 5 scaled up.

How to brief an agent

Objective: {one clear goal}

What done looks like: {the exact output you want, like "a table comparing price, reviews, and contract terms, with a one-paragraph recommendation"}

Boundaries: don't contact anyone, don't sign up for anything, don't spend money. {add your own}

If you hit something unclear or can't verify a fact, stop and ask me instead of improvising.
