Building agentic workflows is difficult due to the complexity of context management and tool orchestration. This SDK abstracts those infrastructure hurdles, allowing engineers to focus on product logic while leveraging a production-tested agentic loop.
Building agentic workflows from scratch is hard.
You have to manage context across turns, orchestrate tools and commands, route between models, integrate MCP servers, and think through permissions, safety boundaries, and failure modes. Even before you reach your actual product logic, you’ve already built a small platform.
GitHub Copilot SDK (now in technical preview) removes that burden. It allows you to take the same Copilot agentic core that powers GitHub Copilot CLI and embed it in any application.
This gives you programmatic access to the same production-tested execution loop that powers GitHub Copilot CLI. That means instead of wiring your own planner, tool loop, and runtime, you can embed that agentic loop directly into your application and build on top of it for any use case.
You also get Copilot CLI’s support for multiple AI models, custom tool definitions, MCP server integration, GitHub authentication, and real-time streaming.
Copilot CLI lets you plan projects or features, modify files, run commands, use custom agents, delegate tasks to the cloud, and more, all without leaving your terminal.
Since we first introduced it, we’ve been expanding Copilot’s agentic workflows so it:
The SDK takes the agentic power of Copilot CLI (the planning, tool use, and multi-turn execution loop) and makes it available in your favorite programming language. This makes it possible to integrate Copilot into any environment. You can build GUIs that use AI workflows, create personal tools that level up your productivity, or run custom internal agents in your enterprise workflows.
Our teams have already used it to build things like:
Think of the Copilot SDK as an execution platform that lets you reuse the same agentic loop behind the Copilot CLI, while GitHub handles authentication, model management, MCP servers, custom agents, and chat sessions plus streaming. That means you are in control of what gets built on top of those building blocks.

It provides a blueprint for building agentic workflows that enhance human productivity and ensure critical user feedback is never lost in the backlog.
AI is fundamentally reshaping the tech stack by favoring languages like TypeScript that provide better constraints for LLMs. Octoverse 2025 data shows that AI reduces the friction of complex syntax, making reliability and utility the primary drivers of developer choice over ease of use.
This report highlights a shift where AI-assisted workflows favor typed languages like TypeScript for reliability. It also underscores Python's dominance in the AI ecosystem as projects move from experimentation to production-ready infrastructure, signaling new defaults for modern dev teams.
As AI-generated code becomes more prevalent, type systems provide a critical safety net by catching the high volume of errors (94%) introduced by LLMs. This shift ensures reliability and maintainability in projects where developers no longer write every line of code manually.
