Asking GitHub Copilot questions in GitHub.com

Overview

GitHub Copilot Chat in GitHub.com is a chat interface that lets you ask and receive answers to coding-related questions on GitHub.com.

Copilot Chat can help you with a variety of coding-related tasks, like offering you code suggestions, providing natural language descriptions of a piece of code's functionality and purpose, generating unit tests for your code, and proposing fixes for bugs in your code. For more information, see "Responsible use of GitHub Copilot Chat in GitHub.com."

On GitHub.com, you can use Copilot Chat to ask:

• General software-related questions, without a particular context. For more information, see "Asking a general question about software development."
• Exploratory questions asked in the context of a specific repository. For more information, see "Asking exploratory questions about a repository."
• Questions asked in the context of a specific repository, file or symbol. For more information, see "Asking a question about a specific file or symbol."
• Questions asked in the context of a knowledge base (that is, Markdown documentation across one or more repositories). For more information, see "Asking a question about a knowledge base."
• Questions about a specific file or specified lines of code within a file. For more information, see "Asking questions about specific pieces of code."
• Questions about a pull request diff. For more information, see "Finding out about the changes in a pull request."
• Questions about a specific issue. For more information, see "Asking a question about a specific issue or discussion."

Limitations

• Chat responses may be suboptimal if you ask questions about a specific repository that you've selected as a context, and the repository has not been indexed for semantic code search. Anyone who gets access to Copilot from the organization that owns a repository can index that repository. For more information, see "Asking exploratory questions about a repository."
• The quality of the results from Copilot Chat may, in some situations, be degraded if very large files, or a large number of files, are used as a context for a question.

Asking a general question about software development

You can ask a general question about software development that is not focused on a particular context, such as a repository or a knowledge base.

Depending on the question you ask, and your enterprise and organization settings, Copilot may respond using information based on the results of a Bing search. By using Bing search, Copilot can answer a broad range of tech-related questions with up-to-date details based on information currently available on the internet. For information on how to enable or disable Bing search integration, see "엔터프라이즈에서 Copilot Business에 대한 정책과 기능 관리하기."
