Introduction

You can use third-party coding agents alongside Copilot クラウドエージェント to work asynchronously on your development tasks. You can assign an existing issue or give a prompt to an agent, which will work on the required changes and create a pull request. When the agent finishes, it will request a review from you, and you can leave pull request comments to ask the agent to iterate.

Coding agents are subject to the same security protections, mitigations, and limitations as Copilot クラウドエージェント. To learn more about how you can use coding agents, see クラウド エージェントGitHub Copilotについて.

Where you can use coding agents

You can kick off tasks with coding agents in the following locations:

  • The Agents tab: Select an agent under the prompt box in the Agents tab, then kick off a new task and watch the agent get to work on a pull request.
  • Issues: Assign the agent to an existing issue in a repository.
  • Pull requests: Mention @AGENT_NAME in a comment on an existing pull request to ask it to make changes.
  • On GitHub Mobile: From the Home view, click to start a new agent session.
  • In Visual Studio Code: Start a new session in the chat view, or delegate an existing session to a different agent.

Making coding agents available

Before you can assign tasks to coding agents on GitHub, they must be enabled in your account policies.

These policies do not apply to local agents in Visual Studio Code. To configure agent settings in Visual Studio Code, see Types of agents in the Visual Studio Code documentation. To adjust enterprise agent settings in Visual Studio Code, see Enable or disable the use of agents in the Visual Studio Code documentation.

Supported coding agents

The following third-party agents are supported on GitHub:

AI models for third-party agents

When starting a task with a third-party agent, you can select the AI model used by the agent. You may find that different models perform better, or provide more useful responses, depending on the type of task. For help deciding which model to use, see AI モデルの比較.

You can also select Auto, which allows Copilot自動モデルの選択 to choose the best available model on your behalf. See について Copilot自動モデルの選択.

The following models are available for each agent:

OpenAI Codex

  • Auto
  • GPT-5.2-Codex
  • GPT-5.3-Codex
  • GPT-5.4
  • GPT-5.4 nano

Anthropic Claude

  • Auto
  • クロード作品4.5
  • クロード作品4.6
  • Claude Opus 4.7
  • クロード・ソネット 4.5
  • クロード・ソネット 4.6

Usage costs

Coding agents consume GitHub Actions minutes and AI credits. Each agent session consumes AI credits based on the model used and the number of tokens processed.

Within your included GitHub Actions minutes and AI credits, you can use agents without incurring additional costs. See 組織と企業の使用量ベースの課金.

Partner agents

When enabling partner agents in your user or organization Copilot クラウドエージェント settings, a GitHub App will be installed for the corresponding agent.

  • Allow Claude coding agent will install anthropic code agent
  • Allow Codex coding agent will install openai code agent

Actions taken by these GitHub Apps will be visible in your audit log, but the GitHub Apps themselves will not be visible in your account's list of GitHub App installations.
