GitHub Copilot SDK

GitHub says the Copilot SDK is generally available for embedding agentic coding workflows with planning, tool invocation, file edits, streaming, multi-turn sessions, MCP, hooks, OpenTelemetry tracing, and bring-your-own-key authentication. Why it matters: Agent features are moving from chat sidebars into programmable runtimes that can be instrumented, constrained, and embedded in development workflows.

Try this: Prototype a small repository-maintenance assistant that uses hooks and tracing before adding broad tool access.
