GitHub Copilot SDK

Overview

The GitHub Copilot SDK exposes the same Copilot CLI agent runtime over JSON-RPC, so apps can drive Copilot programmatically instead of building their own orchestration layer.

Status: Public preview
SDKs: Node.js/TypeScript, Python, Go, .NET, Java
Architecture: Application -> SDK client -> JSON-RPC -> Copilot CLI

How to use this skill

When helping with the Copilot SDK:

1. Prefer the official docs index and the language-specific README over memory.
2. Treat the top-level SDK README plus docs/ as the source of truth for shared behavior.
3. Call out preview status when stability or breaking changes matter.
4. Avoid hardcoding model lists when runtime discovery via listModels() is available.
5. Watch for stale guidance around permissions, lifecycle methods, and event names.
