Privatemode AI for GitHub Copilot

Enable confidential AI coding features with Privatemode in VS Code's GitHub Copilot Chat. Privatemode uses Confidential Computing to keep your prompts end-to-end encrypted—even Privatemode itself cannot access them in plaintext. Developed by Edgeless Systems.

⚠️ Preview: This extension is currently in preview. Features and APIs may change as we gather feedback and improve the extension.

⚡ Quick start for developers

1. Clone the repository and open it in VS Code (>= v1.104.0).

2. Install dependencies and build the extension:

   npm install
   npm run compile

3. Launch a development host (F5) which starts an Extension Development Host with the extension pre‑loaded.

4. Ensure the Privatemode Proxy is running locally on localhost:8080 (see the proxy guide below).

5. Open the VS Code Chat view, select the model picker → Manage Models…, and choose Privatemode as the provider.

6. (Optional) Add an API key if your proxy is configured without one.

Useful scripts

• npm run compile – Compiles the TypeScript source files into JavaScript (placed in the out/ directory) using the project’s tsconfig.json. Required before running, testing, or packaging the extension.
• npm run watch – Starts the TypeScript compiler in watch mode; it automatically recompiles whenever a source file changes, which is handy during active development.
• npm run lint – Executes ESLint across the code base, reporting style violations and potential bugs according to the configured linting rules.
• npm run format – Formats all source files with Prettier, enforcing a consistent code style throughout the project.
• npm run test – First runs npm run compile, then launches VS Code in a head‑less test runner (@vscode/test-cli) and executes the Mocha test suite located in src/test/. The command exits with a non‑zero status if any test fails.

🏠 Privatemode Proxy

The Privatemode Proxy is a self‑hosted service that serves as your local API endpoint for the Privatemode API. It handles encryption of prompts, decryption of responses, and verification of the remote Privatemode deployment through attestation.

📦 Packaging and installing
