Asking GitHub Copilot questions in GitHub Mobile

Overview

GitHub Copilot Chat is a chat interface that lets you ask and receive answers to coding-related questions in GitHub Mobile. You can also use GitHub Copilot Chat on either GitHub or within a supported IDE. For information on using GitHub Copilot Chat in an IDE, see Asking GitHub Copilot questions in your IDE.

Copilot Chat in GitHub Mobile 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 GitHub Mobile での GitHub Copilot Chat の責任ある使用.

In GitHub Mobile, 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.
• Questions asked in the context of your project. For more information, see Asking questions about a specific repository.
• Questions about a specific file or specified lines of code within a file. For more information, see Asking questions about specific pieces of code.

With Copilot Enterprise, you can also ask:

• Questions about a specific pull request. For more information, see Asking questions about a specific pull request.
• Questions about a specific issue. For more information, see Asking questions about a specific issue.
• Questions about a specific discussion. For more information, see Asking questions about a specific discussion.

Limitations

The following limitations apply to Copilot Chat in GitHub Mobile:

• 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.

Prerequisites

To use Copilot Chat in GitHub Mobile, click the Copilot icon in GitHub Mobile to initiate a chat. If you don't already have an active GitHub Copilot subscription, you will automatically get subscribed to Copilot Free.

If you are part of an organization or enterprise with a GitHub Copilot Business or GitHub Copilot Enterprise subscription, the organization or enterprise owner may need to grant you access to Copilot Chat in GitHub Mobile. For more information, see organization 内での Copilot のポリシーの管理.

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.

1. In GitHub Mobile, tap the GitHub Copilot icon in the bottom right corner of the screen.

   Note

   The GitHub Copilot icon is not shown on every page in GitHub Mobile. If you don't see the icon, navigate to a different page in GitHub Mobile and look for the icon there.

2. If the page displays a previous conversation you had with Copilot, tap in the top right corner of the screen, and then tap New conversation .

3. At the bottom of the page, in the "Ask Copilot" box, type a question and send the message.

   Some examples of general questions you could ask are:

   • What are the advantages of the Go programming language?
   • What is Agile software development?
   • What is the most popular JavaScript framework?
   • Give me some examples of regular expressions.
   • Write a bash script to output today's date.

4. Within a conversation thread, you can ask follow-up questions. Copilot will answer within the context of the conversation. For example, you could type "tell me more" to get Copilot to expand on its last comment.

   You can use your initial question as a foundation for follow-up questions. A detailed foundational prompt can help Copilot provide more relevant answers to your follow-up questions. For more information, see Prompting GitHub Copilot Chat to become your personal AI assistant for accessibility on the GitHub Blog.

5. Copilot で行った以前の会話に戻るには、画面の右上隅にある をタップします。 直近に変更された 3 つの会話のいずれかをタップするか、[すべての会話を表示] をタップします。 これにより、Copilot を使用した以前のすべての会話の一覧が表示されます。

6. 会話を削除するには、画面の右上隅にある をタップし、[会話を削除] をタップします。 これにより、Copilot を使用した以前の会話の一覧から会話が削除されます。

7. 最初からやり直すには、画面の右上隅にある をタップし、[新しい会話] をタップします。

   現在の会話とは無関係な質問をしたい場合は、常に新しい会話を開始する必要があります。

Asking exploratory questions about a repository

You can ask questions about a specific repository, to get help with understanding the code, or to get help with a specific task you're working on.

1. In GitHub Mobile, navigate to a repository, and tap the GitHub Copilot icon in the bottom right corner of the screen.

2. At the bottom of the page, use the "Ask Copilot" box, type a question and send the message.

   For example, if you chose the repository you are working in as the context, you could ask:

   • What is the main purpose of this repo? What problem does it solve or what functionality does it provide?

   • What web frameworks are used in this project?

   • Where is rate limiting implemented in our API?

   • How is the code organized? Explain the project architecture.

   • Are there any specific environment requirements for working on this project?

   Important

   Copilot's ability to answer natural language questions like these in a repository context is improved when the repository has been indexed for semantic code search. Without indexing, Copilot Chat in GitHub Mobile may not be able to provide the most relevant answers to your questions.

   You can't trigger the creation of a semantic code search index for a repository from GitHub Mobile. Instead you must use Copilot Chat in a web browser. See Indexing repositories for Copilot Chat.

3. Copilot で行った以前の会話に戻るには、画面の右上隅にある をタップします。 直近に変更された 3 つの会話のいずれかをタップするか、[すべての会話を表示] をタップします。 これにより、Copilot を使用した以前のすべての会話の一覧が表示されます。

4. 会話を削除するには、画面の右上隅にある をタップし、[会話を削除] をタップします。 これにより、Copilot を使用した以前の会話の一覧から会話が削除されます。
