What this skill does
GitHub Copilot SDK Embed Copilot's agentic workflows in any application using Python, TypeScript, Go, or .NET. Overview The GitHub Copilot SDK exposes the same engine behind Copilot CLI: a production-tested agent runtime you can invoke programmatically. No need to build your own orchestration - you define agent behavior, Copilot handles planning, tool invocation, file edits, and more. Prerequisites 1. GitHub Copilot access and an authenticated environment 2. Language runtime: Node.js ^20.19.0 or >=22.12.0, Python 3.11+, Go 1.24+, or a .NET Standard 2.0-compatible implementation 3. Go: GitHub Copilot CLI installed and authenticated (Installation guide) The TypeScript, Python, and .NET packages use a bundled Copilot runtime by default, so they do not need a separate CLI installation. Installation Node.js/TypeScript Python Published Python wheels include a pinned runtime version. The pre-download command caches that runtime locally; if skipped, the SDK attempts to download it automatically on first use. Go .NET Quick Start TypeScript Run: npx tsx index.ts Python Go .NET (C#) Run: dotnet run Streaming Responses Enable real-time output for better UX: TypeScript Python Go .NET Custom Tools Define tools that Copilot can invoke during reasoning. When you define a tool, you tell Copilot: 1. What the tool does (description) 2. What parameters it needs (schema) 3. What code to run (handler) TypeScript (JSON Schema) Python (Pydantic) Go .NET (Microsoft.Extensions.AI) How Tools Work When Copilot decides to call your tool: 1. Copilot sends a tool call request with the parameters 2. The SDK runs your handler function 3. The result is sent back to Copilot 4. Copilot incorporates the result into its response Copilot decides when to call your tool based on the user's question and your tool's description.
