how-to-build-a-coding-agent

Why we included this project

This workshop takes the mystery out of how coding agents like Cursor or Cline work by having you build six small Go programs, starting with a bare Claude chatbot and adding file reading, folder exploration, shell commands, file editing, and code search one step at a time. Because each new capability lands as a small piece of working code, the event loop and tool registry stop being abstract concepts and become things you have implemented yourself. It is aimed at Go developers who want a hands-on introduction rather than a production framework, and the exercise doubles as a mental model for how commercial tools handle tool requests and errors. Teams planning an internal assistant will find it a practical on-ramp before reaching for a heavier framework.
