You can use Copilot Extensions to interact with external tools in GitHub Copilot Chat.
Anyone with a GitHub Copilot Pro or Copilot Free subscription can use Copilot Extensions.
For organizations or enterprises with a Copilot Business or Copilot Enterprise subscription, organization owners and enterprise administrators can grant access to Copilot Extensions.
Copilot Extensions is not available for GitHub Enterprise Server.
GitHub Copilot Extensions are a type of GitHub App that integrates the power of external tools into GitHub Copilot Chat. Copilot Extensions can be developed by anyone, for private or public use, and can be shared with others through the GitHub Marketplace.
Note
GitHub Copilot Extensions are not the same as the GitHub Copilot extension, which you install in your IDE to use default Copilot functionality like code completions and GitHub Copilot Chat. For more information on the GitHub Copilot extension, see Getting code suggestions in your IDE with GitHub Copilot.
You can get started with Copilot Extensions in one of two ways:
You can interact with your custom-built or installed extension in a Copilot Chat conversation, asking questions and performing actions that combine the capabilities of the external tool and GitHub. For example, if you install the Sentry extension for GitHub Copilot, you can use the extension to get information about Sentry issues, then create and assign related tracking issues on GitHub.
Copilot Extensions provide several benefits, including:
Copilot Extensions are included in all Copilot subscriptions.
If you have a Copilot Pro subscription, you need to install a Copilot Extension before you can use the extension in Copilot Chat. See Extending the capabilities of GitHub Copilot in your personal account.
If you have access to Copilot through a Copilot Business or Copilot Enterprise subscription:
To start using a Copilot Extension, open a supported Copilot Chat interface. See Supported clients and IDEs.
To see a list of all Copilot Extensions available in your Copilot Chat conversation, in the Copilot Chat text box, type @.
@
If you are using Copilot Chat in an IDE, and you or your organization owner install a Copilot Extension while your IDE is open, you need to restart your IDE to begin using the Copilot Extension.
In the list of available Copilot Extensions, click the one you want to use.
To begin interacting with the Copilot Extension, in the Copilot Chat text box, ask the extension to answer a question or perform an action, then press Enter. For each new request, be sure to include @EXTENSION-NAME at the beginning of your sentence.
@EXTENSION-NAME
When you are using a Copilot Extension, consider how you would interact with the tool outside of Copilot Chat, then use natural language to ask questions and assign tasks that integrate the capabilities of the tool with GitHub. For example, Sentry is an application monitoring software with a Copilot Extension. The following are some example prompts for the Sentry extension for GitHub Copilot:
@sentry list my most recent issues
@sentry tell me more about issue ISSUE-ID-OR-ISSUE-LINK
@sentry create a GitHub issue for the most recent Sentry issue and assign it to @DEVELOPER
For information on the best ways to use a specific Copilot Extension, read the description of the extension on GitHub Marketplace.
Interactions with one Copilot Extension will never be shared with another Copilot Extension. To interact with different Copilot Extensions in an IDE, change the @EXTENSION-NAME at the beginning of each sentence. Interactions with different extensions will appear in the same Copilot Chat window, but the conversations themselves are automatically separated.
