## :copilot:  Install and run GitHub Copilot CLI directly from `gh`

Since we deprecated the [GitHub Copilot in the CLI](https://github.blog/changelog/2025-09-25-upcoming-deprecation-of-gh-copilot-cli-extension/) extension in favor of the new agentic [GitHub Copilot CLI](https://github.com/github/copilot-cli), we want to give developers using `gh` a simple way to get started using our most powerful terminal assistant.

- `gh copilot` will prompt to install, then run Copilot CLI
- `gh copilot <args>` will execute the Copilot CLI, forwarding any arguments and flags

For more information and usage options, run `gh copilot --help`.
