You don't need to build your own agent harness

GitHub's Copilot SDK (launched in technical preview January 2026) provides a production-grade agent runtime so developers can skip building their own agent harness. It includes a battle-tested execution loop, tool invocation (file system, Git, shell), MCP server integration, multi-model routing, authentication, and streaming — all out of the box. Supported languages include Node.js, Python, Go, Java, and .NET. The pitch is straightforward: instead of spending weeks on orchestration infrastructure, embed the same loop powering Copilot CLI and focus on product logic. Code examples show minimal setup in Python and .NET. The post is the first in a planned series covering session management, deployment, tool customization, MCP integration, and multi-agent patterns.
