Asking GitHub Copilot to create a pull request

Introduction

You can ask Copilot to create a new pull request from:

• GitHub Issues, by assigning an issue to Copilot
• The agents tab or panel on GitHub
• The dashboard on GitHub
• Copilot Chat in Visual Studio Code, JetBrains IDEs, Eclipse and Visual Studio 2026
• Copilot Chat on GitHub.com
• The GitHub CLI
• On GitHub Mobile
• Your preferred IDE or agentic coding tool with Model Context Protocol (MCP) support
• The Raycast launcher
• The "New repository" form on GitHub

Copilot will start working on the task, raise a pull request, then request a review from you when it's finished working. For more information, see About GitHub Copilot cloud agent.

Assigning an issue to Copilot

You can ask Copilot to start working on an issue by assigning the issue to Copilot.

You can assign an issue to Copilot:

• On GitHub.com (see the next section)
• On GitHub Mobile
• Via the GitHub API (see later in this article)
• Using the Raycast launcher
• Using GitHub CLI (see gh issue edit)

Assigning an issue to Copilot on GitHub.com

1. GitHub で、リポジトリのメイン ページに移動します。

2. リポジトリ名の下にある [Issues] をクリックします。

   

3. Open the issue that you want to assign to Copilot.

4. In the right side menu, click Assignees.

   

5. Click Copilot from assignees list.

   

   Additional options are displayed.

   

6. In the Optional prompt field you can add specific guidance for Copilot. Add any context, constraints, or specific requirements that will help Copilot to understand and complete the task.

   For example, you might include instructions about specific coding patterns or frameworks to use, testing requirements, code style preferences, files or directories that should or shouldn't be modified.

   In addition to the details you supply here, Copilot will use any custom instructions that have been configured for the target repository. See GitHub Copilot用のリポジトリカスタム命令の追加.

7. You can use the dropdown menus in the dialog to change the repository that Copilot will work in and the branch that it will branch off from.

   All repositories where you have at least read access will be displayed in the repository dropdown menu. However, you can only select a repository if you have write access to it, and if Copilot cloud agent is enabled for that repository.

   If you select a repository in a different organization than the issue's source organization, or if you select a public repository when the issue is in a private repository, a warning will be displayed.

   If you don't specify a repository, Copilot will work in the same repository as the issue. If you don't specify a branch, Copilot will work from the default branch of the selected repository.

   ヒント

   When you assign an issue to Copilot, it gets sent the issue title, description, any comments that currently exist, and any additional instructions you provide. After assigning the issue, Copilot will not be aware of, and therefore won't react to, any further comments that are added to the issue. If you have more information, or changes to the original requirement, add this as a comment in the pull request that Copilot raises.

8. 必要に応じて、 をクリックして、エージェントまたは特殊な動作とツールを使用する カスタム エージェント を割り当てる場合は、エージェントのドロップダウン メニューを開くことができます。 リポジトリ、組織、またはエンタープライズから既存の カスタム エージェント を選択できます。 エージェントの作成] をクリックして、選択したリポジトリとブランチに新しいエージェント プロファイルを作成することもできます。 詳しくは、「Creating custom agents for Copilot cloud agent」をご覧ください。

   メモ

   サード パーティ製のコーディング エージェントは、 GitHub Copilot Pro+ および Copilot Enterprise プランで使用できます。

9. Optionally, if you are a GitHub Copilot Pro or GitHub Copilot Pro+ user, you can use the dropdown menu to select the model that Copilot will use. For more information, see Changing the AI model for GitHub Copilot cloud agent.

You can also assign issues to Copilot from other places on GitHub.com:

• From the list of issues on a repository's Issues page.
• When viewing an issue in GitHub プロジェクト.

6. Beside "Copilot", click the plus sign.
7. Click Done.

Assigning an issue to Copilot via the GitHub API

You can assign issues to Copilot using either the GraphQL API or the REST API. Both APIs support an optional Agent Assignment input to customize the task:

Using the GraphQL API

You can use the following GraphQL mutations to assign issues to Copilot:

• updateIssue
• createIssue
• addAssigneesToAssignable
• replaceActorsForAssignable

Creating and assigning a new issue

1. Make sure you're authenticating with the API using a user token, for example a personal access token or a GitHub App user-to-server token.

   メモ

   If using a fine-grained personal access token, it needs the following permissions to assign Copilot to an issue:

   • Read access to metadata
   • Read and write access to actions, contents, issues and pull requests

   If using a personal access token (classic), it needs the repo scope to assign Copilot to an issue.

2. Verify that Copilot cloud agent is enabled in the repository by checking if the repository's suggestedActors in the GraphQL API includes Copilot. Replace octo-org with the repository owner, and octo-repo with the repository name.

   GraphQL

   query {
     repository(owner: "octo-org", name: "octo-repo") {
       suggestedActors(capabilities: [CAN_BE_ASSIGNED], first: 100) {
         nodes {
           login
           __typename
   
           ... on Bot {
             id
           }
   
           ... on User {
             id
           }
         }
       }
     }
   }
   

   If Copilot cloud agent is enabled for the user and in the repository, the first node returned from the query will have the login value copilot-swe-agent.

3. Make a note of the id value of this login.

4. Fetch the GraphQL global ID of the repository you want to create the issue in, replacing octo-org with the repository owner, and octo-repo with the repository name.

   GraphQL

   query {
     repository(owner: "octo-org", name: "octo-repo") {
       id
     }
   }
   

5. Create the issue with the createIssue mutation. Replace REPOSITORY_ID with the ID returned from the previous step, and BOT_ID with the ID returned from the step before that. You can optionally include the agentAssignment input to customize the task.

   Shell

   gh api graphql -f query='mutation {
     createIssue(input: {
       repositoryId: "REPOSITORY_ID",
       title: "Implement comprehensive unit tests",
       body: "DETAILS",
       assigneeIds: ["BOT_ID"],
       agentAssignment: {
         targetRepositoryId: "REPOSITORY_ID",
         baseRef: "main",
         customInstructions: "Add comprehensive test coverage",
         customAgent: "",
         model: ""
       }
     }) {
       issue {
         id
         title
         assignees(first: 10) {
           nodes {
             login
           }
         }
       }
     }
   }' -H 'GraphQL-Features: issues_copilot_assignment_api_support,coding_agent_model_selection'
   

Assigning an existing issue

1. Make sure you're authenticating with the API using a user token, for example a personal access token or a GitHub App user-to-server token.

2. Verify that Copilot cloud agent is enabled in the repository by checking if the repository's suggestedActors in the GraphQL API includes Copilot. Replace octo-org with the repository owner, and octo-repo with the repository name.

   GraphQL

   query {
     repository(owner: "monalisa", name: "octocat") {
       suggestedActors(capabilities: [CAN_BE_ASSIGNED], first: 100) {
         nodes {
           login
           __typename
   
           ... on Bot {
             id
           }
   
           ... on User {
             id
           }
         }
       }
     }
   }
   

   If Copilot cloud agent is enabled for the user and in the repository, the first node returned from the query will have the login value copilot-swe-agent.

3. Fetch the GraphQL global ID of the issue you want to assign to Copilot, replacing monalisa with the repository owner, octocat with the name and 9000 with the issue number.

   GraphQL

   query {
     repository(owner: "monalisa", name: "octocat") {
       issue(number: 9000) {
         id
         title
       }
     }
   }
   

4. Assign the existing issue to Copilot using the replaceActorsForAssignable mutation. Replace ISSUE_ID with the ID returned from the previous step, BOT_ID with the ID returned from the step before that, and REPOSITORY_ID with the repository ID. You can optionally include the agentAssignment input to customize the task.

   Shell

   gh api graphql -f query='mutation {
     replaceActorsForAssignable(input: {
       assignableId: "ISSUE_ID",
       actorIds: ["BOT_ID"],
       agentAssignment: {
         targetRepositoryId: "REPOSITORY_ID",
         baseRef: "main",
         customInstructions: "Fix the reported bug",
         customAgent: "",
         model: ""
       }
     }) {
       assignable {
         ... on Issue {
           id
           title
           assignees(first: 10) {
             nodes {
               login
             }
           }
         }
       }
     }
   }' -H 'GraphQL-Features: issues_copilot_assignment_api_support,coding_agent_model_selection'
   

5. Alternatively, you can use the updateIssue mutation to update an existing issue and assign it to Copilot. Replace ISSUE_ID with the issue ID and BOT_ID with the bot ID.

   Shell

   gh api graphql -f query='mutation {
     updateIssue(input: {
       id: "ISSUE_ID",
       assigneeIds: ["BOT_ID"],
       agentAssignment: {
         targetRepositoryId: "REPOSITORY_ID",
         baseRef: "main",
         customInstructions: "Update feature implementation",
         customAgent: "",
         model: ""
       }
     }) {
       issue {
         id
         title
         assignees(first: 10) {
           nodes {
             login
           }
         }
       }
     }
   }' -H 'GraphQL-Features: issues_copilot_assignment_api_support,coding_agent_model_selection'
   

6. You can also use the addAssigneesToAssignable mutation to add Copilot to an existing issue while keeping other assignees. Replace ISSUE_ID with the issue ID and BOT_ID with the bot ID.

   Shell

   gh api graphql -f query='mutation {
     addAssigneesToAssignable(input: {
       assignableId: "ISSUE_ID",
       assigneeIds: ["BOT_ID"],
       agentAssignment: {
         targetRepositoryId: "REPOSITORY_ID",
         baseRef: "main",
         customInstructions: "Collaborate on this task",
         customAgent: "",
         model: ""
       }
     }) {
       assignable {
         ... on Issue {
           id
           title
           assignees(first: 10) {
             nodes {
               login
             }
           }
         }
       }
     }
   }' -H 'GraphQL-Features: issues_copilot_assignment_api_support,coding_agent_model_selection'

Asking Copilot to create a pull request from the GitHub CLI

You can start a new Copilot cloud agent session with the gh agent-task create command in the GitHub CLI.

When you run the command without any arguments, you are asked to enter a prompt. Copilot cloud agent acts on the prompt and opens a pull request in the current repository.

You can use command line options to:

• Provide the prompt (gh agent-task create "Example prompt")
• Choose a base branch, instead of using the repository's default branch (--base)
• Select a repository, instead of targeting the current repository (--repo)
• Follow the session log in real time (--follow)

To see all of the available options, run gh agent-task create --help.
