Lesson 7: Problem Solving with Vibe Coding and Agentic AI
What is an agent?
You've seen how AI can help build things when you keep prompting it. What happens when AI can take steps on its own?
A chatbot replies to your prompts. An AI agent is software that uses an LLM to work towards a goal. It can plan steps, use tools, check results and fix mistakes. Sometimes this is called Agentic AI.
| Chatbot | Agent |
|---|---|
| Prompt: "How do I make a dice game?" | Goal: "Make me a dice game" |
| Reply: Explains the steps and maybe gives code. | Result: Creates the files, writes the code, runs it, finds an error, fixes it, and tells you what changed. |
The video below shows an agent (OpenAI Codex) being used to generate and make fixes to a Tic Tac Toe game. The agent opens up a browser (Internet Edge) and text editor (Notepad) to create a web game for Tic Tac Toe (also known as noughts and crosses).
