Using keywords in your prompt

You can use special keywords to help Copilot understand your prompt. For examples, see Getting started with prompts for Copilot Chat.

Chat participants

Chat participants are AI domain experts that can perform tasks or answer questions in a specific domain.

Copilot Chat can infer relevant chat participants based on your natural language prompt, improving discovery of advanced capabilities without you having to explicitly specify the participant you want to use in your prompt. However, if you prefer, you can still manually specify a chat participant to scope your prompt to a specific domain. To do this, type @ in the chat prompt box, followed by a chat participant name.

Note

Automatic inference for chat participants is currently in public preview and is subject to change.

Chat participants include:

  • @workspace: Has context about the code in your workspace. Use @workspace when you want Copilot to consider the structure of your project, how different parts of your code interact, or design patterns in your project.
  • @vscode: Has context about Visual Studio Code commands and features. Use @vscode when you want help with Visual Studio Code.
  • @terminal: Has context about the Visual Studio Code terminal shell and its contents. Use @terminal when you want help creating or debugging terminal commands.
  • @azure: Has context about Azure services and how to use, deploy and manage them. Use @azure when you want help with Azure. The @azure chat participant is currently in public preview and is subject to change.

In addition to the built-in Visual Studio Code chat participants, you can also install Copilot Extensions that provide chat participants. You can install these extensions from GitHub Marketplace and from Visual Studio Code Marketplace. For information about extensions from GitHub Marketplace that provide chat participants, see Using extensions to integrate external tools with Copilot Chat.

Note

GitHub Copilot Extensions is in public preview and subject to change.

To see all available chat participants, type @ in the chat prompt box.

See also Chat participants in the Visual Studio Code documentation.

Slash commands

Use slash commands to avoid writing complex prompts for common scenarios. To use a slash command, type / in the chat prompt box, followed by a command. Slash commands include:

  • /tests: Generate unit tests for the selected code
  • /fix: Propose a fix for problems in the selected code
  • /explain: Explain the selected code
  • /clear: Start a new chat

To see all available slash commands, type / in the chat prompt box. See also Slash commands in the Visual Studio Code documentation.

Chat variables

Use chat variables to include specific context in your prompt. To use a chat variable, type # in the chat prompt box, followed by a chat variable. Chat variables include:

  • #file: Include a specific file as context in the chat.
  • #git: Include information about the current Git repository.
  • #terminalLastCommand: Include the last run command in the active Visual Studio Code terminal.

To see all available chat variables, type # in the chat prompt box. See also Chat variables in the Visual Studio Code documentation.

Using GitHub skills for Copilot

Note

This functionality is available with the Copilot Chat extension v0.20.3 or later and VS Code or VS Code Insiders 1.93 or later.

Copilot's GitHub-specific skills expand the type of information Copilot can provide. To access these skills in Copilot Chat in VS Code, include @github in your question.

When you add @github to a question, Copilot dynamically selects an appropriate skill, based on the content of your question. You can also explicitly ask Copilot Chat to use a particular skill. You can do this in two ways:

  • Use natural language to ask Copilot Chat to use a skill. For example, @github Search the web to find the latest GPT4 model from OpenAI.
  • To specifically invoke a web search you can include the #web variable in your question. For example, @github #web What is the latest LTS of Node.js?
