Build Your First AI Agent: A Step-by-Step Tutorial (No PhD Required)

1. What Exactly Is an AI Agent? (And Why You Should Care)

• Define an AI agent vs. a simple chatbot: autonomy, tool-use, and memory.
• Real-world examples: customer support bots, code assistants, and automation pipelines.
• Key components every agent needs: LLM backbone, tools/APIs, and an orchestration loop.

2. Setting Up Your Environment in Under 10 Minutes

• Python environment with `pip install openai langchain chromadb` (or equivalent).
• Get your API key from OpenAI / Anthropic / Ollama (local option).
• Project folder structure: `agent.py`, `tools/`, `memory/`, and a `.env` file.

3. Wiring the Brain: Connect to an LLM with a System Prompt

• Write a system prompt that defines the agent’s role, tone, and constraints.
• Initialize the LLM client and test a simple “hello world” completion.
