Learning Outcomes
What you'll learn
The day after you finish
The day after this course, you can open a blank folder, write a new Python tool function, add its JSON schema, drop it into the agent loop, and watch the model call it correctly β without looking anything up.
Who this is for
- Primary: IT professionals and junior developers who can write basic Python (loops, functions, dicts) but have never called an LLM API, never used any AI library, and have no idea what tool calling or an agent loop is.
- Secondary: Anyone curious about AI agents who wants to understand exactly how they work by building one from scratch.
Prerequisites
- Can write basic Python: loops, functions, dictionaries, if/else
- Comfortable running commands in a terminal
- No prior AI, ML, LangChain, or OpenAI experience required

Personal Utility Agent β Working HTTP API
A personal utility agent (get_current_time, calculate_math, save_note) running as a FastAPI server. POST /chat accepts a natural-language request, routes to the right tool, executes it, and returns an answer. All tool functions have passing pytest tests.
