GitHub Copilot CLI
Copilot as a terminal agent, with GitHub itself — issues, pull requests, Git — within reach.
GitHub Copilot CLI brings Copilot into the terminal as an agent that can answer questions, write and debug code, and act on GitHub.com: modify a project, open a pull request, manage issues, run Git operations. It runs on Linux, macOS and Windows (PowerShell and WSL). It is not sold separately: GitHub states that all Copilot plans include it, from Free through Pro ($10), Pro+ ($39) and Max ($100) to Business and Enterprise, with usage drawing on the plan's AI credits.
Most people meet this tool through a comparison - against Gemini CLI, or against Claude Code - and the comparison usually hides the deciding fact: this one is already paid for. If your organisation has Copilot seats, the CLI arrives with them, inside the same billing, identity and policy controls your admins approved. That is a procurement argument rather than a capability one, and in larger companies it tends to win.
Our take
The default terminal agent for anyone whose company already pays for Copilot, and a reasonable free starting point for everyone else. Its real edge is reach into GitHub: issues and pull requests are first-class rather than shelled out to. If your work does not live on GitHub, that edge disappears and the choice should be made on the agent alone.
