Summary

You learned how GitHub Copilot works inside the IDE and terminal to support real work, not just completions: prompting from the terminal and Command Palette, using GitHub Copilot CLI to generate and explain scripts, asking for help while debugging to interpret stack traces and suggest fixes, and running local reviews to produce clear commit messages and manual pull request summaries. You also saw test runners and code analysis in action, along with practical scenarios that tie these pieces together. This matters because it keeps you in one flow. You can script, review, test, and debug with less context switching, clearer documentation, and safer execution when you review suggestions before running them.

In the next chapter, you’ll see how GitHub Copilot extends beyond local development to enhance collaboration on GitHub.com itself, where it summarizes pull requests, assists with code reviews, and streamlines web-based automation to help teams work more efficiently...
