GitHub Copilot

Updated: Mar 12, 2026

Overview

GitHub Copilot⁠ auto-loads .github/copilot-instructions.md when you open a project in VS Code. The SDK knowledge is available in Copilot Chat immediately.
Copilot also provides inline completions as you write DAT SDK code — the project config gives it enough context to suggest correct API usage, parameter names, and patterns.

Setup

If you cloned the SDK repo, the .github/copilot-instructions.md file is already included. Otherwise, install with the CLI:
./install-skills.sh copilot
Or install remotely:
iOS:
curl -sL https://raw.githubusercontent.com/facebook/meta-wearables-dat-ios/main/install-skills.sh | bash -s copilot
Android:
curl -sL https://raw.githubusercontent.com/facebook/meta-wearables-dat-android/main/install-skills.sh | bash -s copilot

Usage

Use Copilot Chat to ask SDK questions directly:
How do I request camera permissions in my iOS DAT app?

Adding the API reference

The project-level config covers integration patterns and best practices. To also pull in the full API reference during a chat session, paste the URL directly into your Copilot Chat prompt:
Using https://wearables.developer.meta.com/llms.txt?full=true as reference,
what parameters does MWDATCameraSession.startStreaming accept?
Copilot Chat fetches and reads URL contents automatically when you include them in your prompt.
