This makes sure that if folks get a relatively recent `vscode.d.ts`. It also lets us safely bump up the target to es2024 so you can use all the latest lib additions
Chat Example
Visual Studio Code's Copilot Chat architecture enables extension authors to integrate with the GitHub Copilot Chat experience. A chat extension is a VS Code extension that uses the Chat extension API by contributing a Chat participant. Chat participants are domain experts that can answer user queries within a specific domain.
The Language Model API enables you to use the Language Model and integrate AI-powered features and natural language processing in your Visual Studio Code extension.
When an extension uses the Chat or the Language Model API, we call it a GitHub Copilot Extension, since GitHub Copilot is the provider of the Chat and the Language Model experience.
This GitHub Copilot Extension sample shows:
- How to contribute a simple chat participant to the GitHub Copilot Chat view. (
@cat, simple.ts) - How to use the Language Model API to request access to the Language Model.
- How to use the
@vscode/chat-extension-utilslibrary to easily create a chat participant that uses tools. (@catTools, chatUtilsSample.ts) - How to contribute a more sophisticated chat participant that uses the LanguageModelTool API to contribute and invoke tools. (
@tool, toolParticipant.ts)

About this sample
This sample shows two different ways to build a chat participant in VS Code:
See simple.ts for an example of a simple chat participant that makes requests and responds to user queries. It shows how you can create chat participants with or without the @vscode/prompt-tsx library.
See toolParticipant.ts for an example of a chat participant that invokes tools, either dynamically or using the toolReferences that are attached to the request. This is a more advanced example that shows how you can use the @vscode/prompt-tsx library to implement the LLM tool calling flow and tries to implement all the features of the chat API.
