SKILL.md

Programmatic agent runtime for embedding Copilot's agentic workflows in applications across Python, TypeScript, Go, and .NET.

Exposes the same production-tested engine behind Copilot CLI with support for streaming responses, custom tool definitions, and multi-turn conversations

Supports four language runtimes (Node.js 18+, Python 3.8+, Go 1.21+, .NET 8.0+) with consistent APIs across all platforms

Enables integration with MCP servers for pre-built tools, custom agent personas with specialized prompts, and session persistence across restarts

Includes event-driven architecture for tool invocation, streaming chunks, reasoning visibility, and error handling; configurable client and session options for model selection, timeouts, and resource management

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

GitHub Copilot access and an authenticated environment

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

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.
