Note

For a conceptual overview of {% data variables.copilot.custom_agents_short %}, see AUTOTITLE.

Creating a {% data variables.copilot.copilot_custom_agent_short %} profile for a repository

1. Navigate to the agents tab at https://github.com/copilot/agents.

2. Using the dropdown menu in the prompt box, select the repository you want to create the {% data variables.copilot.copilot_custom_agent_short %} profile in.

   Note

   Organization and enterprise owners can create organization and enterprise-level {% data variables.copilot.custom_agents_short %} in a .github-private repository that are available across all repositories within their organization or enterprise. For more information, see AUTOTITLE and AUTOTITLE.

3. Optionally, select the branch you want to create the {% data variables.copilot.agent_profile %} in. The default is the main branch.

4. Click {% octicon "copilot" aria-label="Select a custom agent" %}, then click {% octicon "plus" aria-label="Plus button" %} Create an agent. This will open a template agent profile called my-agent.md in the .github/agents directory of your target repository.

5. If you are creating an organization or enterprise-level custom agent, delete the .github/ portion of the file path to move your template to the root agents directory.

6. Edit the filename and configure the {% data variables.copilot.agent_profile %}, including the name, description, tools, and prompts. For more information on what the {% data variables.copilot.agent_profile %} can include, see the section below.

7. Commit the file to the repository and merge it into the default branch. Go back to the agents tab and refresh the page if needed. Your custom agent will now appear in the dropdown when you click {% octicon "copilot" aria-hidden="true" aria-label="copilot" %} in the prompt box.

Configuring an {% data variables.copilot.agent_profile %}

An {% data variables.copilot.agent_profile %} is a Markdown file with YAML frontmatter that specifies the {% data variables.copilot.copilot_custom_agent_short %}'s name, description, available tools, and MCP server configurations (for organization/enterprise level agents). Configuring an {% data variables.copilot.agent_profile %} involves defining the agent's identity, capabilities, tool access, and behavioral instructions.

For detailed configuration information about YAML properties, tools, MCP server setup, tool aliases, and how {% data variables.copilot.custom_agents_short %} are processed, see AUTOTITLE.

To configure your {% data variables.copilot.agent_profile %}:

1. Choose a name for your {% data variables.copilot.copilot_custom_agent_short %}. Select a unique, descriptive name that identifies the agent's purpose.
2. Write a brief description explaining what your agent does and its specific capabilities or domain expertise.
3. In the tools property, define which tools the agent can use. This is a list of tool names or aliases, including tools from MCP servers configured in the repository settings or the {% data variables.copilot.agent_profile %} (for example, tools: ["read", "edit", "search", "some-mcp-server/tool-1"]). If you omit this property, the agent will have access to all available tools.
4. If creating an organization or enterprise level agent, you can use the mcp-servers property to optionally configure MCP servers that will be available only to this agent to extend its capabilities.
5. Write the agent's prompt. Define the agent's behavior, expertise, and instructions in the Markdown content below the YAML frontmatter.

Using {% data variables.copilot.custom_agents_short %}

Once you've created a {% data variables.copilot.copilot_custom_agent_short %}, you can use it wherever {% data variables.copilot.copilot_coding_agent %} is available.

• When prompting {% data variables.copilot.copilot_coding_agent %} with a task on {% data variables.product.prodname_dotcom_the_website %}, use the dropdown menu in the agents panel or agents tab to select your {% data variables.copilot.copilot_custom_agent_short %} instead of the default coding agent.
• When assigning {% data variables.copilot.copilot_coding_agent %} to an issue, you can select your {% data variables.copilot.copilot_custom_agent_short %} from the dropdown menu to handle the issue with your specialized configuration.
• When using the {% data variables.copilot.copilot_cli %}, you can choose to use a particular custom agent by using the /agent slash command or referencing the agent in a prompt or via a command-line argument. For more information, see AUTOTITLE.

When {% data variables.product.prodname_copilot_short %} opens pull requests, it will note which {% data variables.copilot.copilot_custom_agent_short %} was used to complete the work in the pull request description.

For more information on using {% data variables.copilot.copilot_coding_agent %}, see AUTOTITLE.

Using {% data variables.copilot.custom_agents_short %} as {% data variables.product.prodname_vscode_shortname %} chat modes

You can also use your custom {% data variables.copilot.agent_profiles %} directly in {% data variables.product.prodname_vscode %} as chat modes. In {% data variables.product.prodname_vscode_shortname %}, you switch between chat modes using the mode dropdown in the Chat view, allowing you to access specialized configurations for different tasks like planning, code editing, or research. For more information, see Use chat modes in {% data variables.product.prodname_vscode_shortname %}.

Note that some properties may function differently between the {% data variables.product.prodname_dotcom_the_website %} and {% data variables.product.prodname_vscode_shortname %} environments. For more information, see AUTOTITLE.
