GitHub Copilot CLI

https://github.blog/changelog/2025-09-25-github-copilot-cli-is-now-in-public-preview/
GitHub Copilot can now also be used from the terminal. The CLI is currently in Public Preview. Supports Linux, macOS, and Windows experimentally (via PowerShell v6+).

By default, it uses the Claude Sonnet 4 model, but also supports GPT-5 via the environment variable COPILOT_MODEL=gpt-5; there is no slash command to switch the model. AI response blocks can be expanded using Ctrl+r.

It uses the GitHub MCP server by default. Provides access to repositories, issues, and pull requests using agent queries.

GitHub Spec Kit and Copilot CLI can be used together. The video shows how to create custom slash commands using additional instruction files.
