Agents First Steps: what an AI agent is and a simple first one

01

What is an AI agent?

In simple words

A chatbot is like a friend you ask questions. An agent is like a helper who can also go and do small jobs for you: look something up, sort a list, check a calendar, then come back and tell you what they did. The more a helper can do on their own, the more carefully you have to watch them.

Key facts

Anthropic's engineering article "Building effective agents" (December 19, 2024) calls these "agentic systems" and splits them in two:
Workflows: the AI and its tools follow steps that you planned in advance.
Agents: the AI decides its own steps and which tools to use, until the task is done.
The article's main advice is to start with the simplest solution and add complexity only when it clearly makes results better. Many tasks need only one well-written prompt.
Agents can cost more and mistakes can add up, so they need testing and guardrails.

Shape	What it is	Example
Single prompt	One question, one answer	"Summarize this email."
Workflow	Fixed steps you designed	Summarize, then draft a reply, then check tone
Agent	The AI picks steps and tools	"Find which orders are late and draft apology emails."

In this course you build the middle of that table: an assistant with clear instructions and your own files. It is "agent-like" and a safe place to learn. Real agents with tools come in course 1.4 and later.

Step by step

Write down three jobs you would like help with this week, one per line.
Next to each job, write "single prompt" if one good request could do it.
Write "workflow" if the steps are always the same (for example summarize, then draft, then check tone).
Write "agent" only if you cannot predict the steps or the tools needed.
Look at your list. Most jobs will be single prompts or workflows. That is normal and good.
Check: each job has a label, and you can say in one sentence why you chose it.

Try it now

List three jobs and label each as single prompt, workflow or agent. Keep the list; you will pick one job from it in Lesson 2.

I'm learning "Agents First Steps: what an AI agent is and a simple first one" on The Future Market. Lesson 1: "What is an AI agent?".

What the lesson teaches:
- Anthropic's engineering article "Building effective agents" (December 19, 2024) calls these "agentic systems" and splits them in two:
- Workflows: the AI and its tools follow steps that you planned in advance.
- Agents: the AI decides its own steps and which tools to use, until the task is done.
- The article's main advice is to start with the simplest solution and add complexity only when it clearly makes results better. Many tasks need only one well-written prompt.
- Agents can cost more and mistakes can add up, so they need testing and guardrails.
- Shape - What it is - Example
- Single prompt - One question, one answer - "Summarize this email."

The exercise I'm working on:
List three jobs and label each as single prompt, workflow or agent. Keep the list; you will pick one job from it in Lesson 2.

I'm stuck. Please:
1. Explain the main idea in plain, simple words with one everyday example.
2. Walk me through the exercise one small step at a time. Ask me what I've done so far before giving the next step.
3. Don't just give me the final answer. Help me do it myself, and check my work when I share it.

I'm a parent helping my child (about 8 years old) with a lesson called "What is an AI agent?" from the course "Agents First Steps: what an AI agent is and a simple first one".

Here's what the lesson says:
A chatbot is like a friend you ask questions. An agent is like a helper who can also go and do small jobs for you: look something up, sort a list, check a calendar, then come back and tell you what they did. The more a helper can do on their own, the more carefully you have to watch them.

The activity:
List three jobs and label each as single prompt, workflow or agent. Keep the list; you will pick one job from it in Lesson 2.

Please explain this so an 8-year-old understands: short sentences, a fun everyday example, and no hard words.
Then give me 3 simple questions I can ask my child to check they understood, and a way to do the activity together, one tiny step at a time.
