The Dirty Secret Behind AI Agents (Demo š)
TL;DR: A coder builds a minimal AI agent in ~80 lines to demystify AI agents and argues frameworks arenāt magical. The piece also shares a personal note about a birthday, conference miscommunication, and introduces a simple code-review agent named Steve.
The author challenges the mystique of AI agents and demonstrates that you can implement a functional agent with minimal code. They explain that frameworks like LangChain or Mastra streamline common tasks but donāt perform magic. A Node.js demo (~80 lines) is used to illustrate how an AI agent can operate, with core loop details acknowledged but not exhaustive. The article blends personal anecdotes (birthday, conference rejection, invites) with a call to explore the underlying mechanisms, and invites readers to view the repository for Steve, a code-review agent with 15 years of experience.
Question for the room: Have you built a minimal AI agent or simplified pipeline that helped you understand the core loop better?
