This tool helps you write, debug, and understand code using everyday language. You just type what you need, and Copilot CLI suggests commands or explains concepts. It uses the same AI as the regular GitHub Copilot. Developers who spend a lot of time in the terminal will love this. It prevents context switching. No more jumping between your IDE and the command line for AI help. It's built for those who want to stay focused in their shell environment. It's also great for managing GitHub tasks.

Imagine asking your terminal to "show me open pull requests" or "create a new issue." Copilot CLI handles it. The tool is agentic. This means it can plan and execute complex coding tasks. It can even help refactor code. But don't worry, you're always in control. Every action needs your explicit approval before it runs. This prevents unexpected changes. It also supports LSP servers.
