## Definition

Copilot SDK is GitHub's multi-language library for embedding the Copilot agent runtime — planning, tool invocation, file editing, and multi-turn sessions — into any application. Not a thin LLM wrapper; it exposes the production-tested orchestration engine powering Copilot CLI, with MCP server support and OpenTelemetry tracing built in.

GitHub shipped the SDK in [technical preview on January 14, 2026](https://github.blog/changelog/2026-01-14-copilot-sdk-in-technical-preview/) for Node.js, Python, Go, and .NET, expanded to public preview on April 2, 2026 with BYOK support (OpenAI, Anthropic, Azure, AWS Bedrock), and reached [general availability on June 2, 2026](https://github.blog/changelog/2026-06-02-copilot-sdk-is-now-generally-available/) adding Rust and Java — 8.9k GitHub stars at GA.

## Example

A CI/CD platform integrates the Python SDK to run a Copilot agent on every pull request: the agent reads the diff, invokes custom grep and test tools, writes inline review comments, and streams the session log — all without GitHub Copilot's UI, using a BYOK Anthropic key billed to the platform operator.

## Analogy

Think of it as a car engine you can drop into any chassis — the orchestration, tools, and memory come pre-assembled.

## Why it's emerging now

GitHub shipped Copilot SDK to GA on June 2, 2026, coinciding with Microsoft Build. It gives any developer the same agent runtime powering Copilot CLI — planning, tool use, file edits, multi-turn sessions — as an embeddable library in six languages, with BYOK for non-Copilot teams and MCP integration included.
