Exercise 02: Your First Pull Request — The Agentic Crew Hands-On Guide

Overview

This chapter is a hands-on exercise. By the end of it, you'll have forked a real repository, created a branch, written a review of a book chapter, and submitted a pull request — the standard way open-source contributors propose changes.

This isn't a simulation. Your pull request will show up on GitHub for real people to read.

This is the open-source workflow. Every contribution to every major project in the world follows these same seven steps. You'll have done all of them by the end of this chapter.
