 ## 💡 Development Tutorial
 
 - I built using [**Agentic Coding**](https://zacharyhuang.substack.com/p/agentic-coding-the-most-fun-way-to), the fastest development paradigm, where humans simply [design](docs/design.md) and agents [code](flow.py).
 
 - The secret weapon is [Pocket Flow](https://github.com/The-Pocket/PocketFlow), a 100-line LLM framework that lets Agents (e.g., Cursor AI) build for you
