The big idea

Modern SDKs handle the loop, tool calling, and memory — you just write the system prompt and define tools.

Some examples

Pick an SDK with a quickstart (Vercel AI SDK is friendly).
Define ONE tool (e.g., a calculator).
Run a prompt that requires the tool — watch the agent call it.

Try it!

Follow a quickstart and build an agent that uses one tool. Push to GitHub.

Understanding "Build your own agent in 30 minutes" in practice: AI agents don't just answer questions — they can do things, like looking things up, writing files, or talking to apps. Use an SDK like Claude Agent SDK or Vercel AI SDK to ship a working agent today — and knowing how to apply this gives you a concrete advantage.

Design clear agent goals before adding tools
Define permissions and scope before deploying any agent
Build in human-approval checkpoints for high-stakes actions
Understand when to use an agent vs. a simple chat prompt

Design an agent spec: goal, tools, permissions, stop condition
Run a simple web-search agent in a sandbox environment
Instrument an existing workflow to identify where an agent could save time

What is the main idea of "Build your own agent in 30 minutes"?
1. Use an SDK like Claude Agent SDK or Vercel AI SDK to ship a working agent today.
2. Use AI as the final authority for the whole decision
3. Avoid checking the answer once it sounds polished
4. Focus only on speed instead of judgment
Which concept is most central to "Build your own agent in 30 minutes"?
1. tool calling
2. SDK
3. unrelated shortcut
4. Use the first answer without checking it
Which use of AI fits this topic best?
1. Let the AI decide what matters without your review
2. Use the answer before checking whether it fits the situation
3. Pick an SDK with a quickstart (Vercel AI SDK is friendly).
4. Use the first answer without checking it
What should a careful learner remember about "Heads up"?
1. Don't add 5 tools on day 1. Get one tool right, then add more.
2. Skip the context so the tool can guess faster
3. Treat the output as private even after sharing it online
4. Use the answer without checking the source
You want to use AI after this lesson. What is the safest next step?
1. Act immediately because the AI answer is written clearly
2. Use the AI answer as a draft, then check it against a reliable source.
3. Hide uncertainty so the final answer looks cleaner
4. Use private or sensitive details before checking permission
How should AI output about SDK be treated?
1. As proof that no other source is needed
2. As a replacement for context, consent, or expert review
3. As a draft or helper output that still needs human judgment and verification
4. As something that becomes correct when it sounds confident
Name one way to verify an AI answer about SDK.
Which action would help you apply "Build your own agent in 30 minutes" responsibly?
1. Use the tool to avoid thinking through the tradeoff
2. Keep going even if the output conflicts with a trusted source
3. Use the first answer without checking it
4. Define ONE tool (e.g., a calculator).
