GitHub Copilot CLI Plugins and Marketplaces: Extend Your Terminal Agent
GitHub Copilot CLI already gives you an AI assistant in the terminal. Plugins make it more powerful by letting you install reusable agents, skills, hooks, and tool integrations as packages.
Instead of manually copying prompt files, wiring MCP servers, or sharing setup notes in a wiki, you can package those capabilities once and install them from a marketplace. In this guide, we will look at how Copilot CLI plugins work, how to find and install them, how marketplaces are structured, and how to build a small plugin of your own.
Quick tip: if you ever forget a flag, run copilot plugin --help or copilot plugin <subcommand> --help. The CLI ships its own up to date reference.
Are these the same as GitHub Copilot Extensions?
