Kit SDK Development Guide

The Kit SDK (pkg/kit) lets you embed Kit's full agent capabilities — LLM interactions, tool execution, session management, streaming, hooks — into any Go application. Unlike extensions (which are interpreted scripts running inside Kit's TUI), SDK programs are standalone compiled Go binaries.

This file is the entry point. It gives the installation, a quick start, the core lifecycle, and the rules you must never miss. Detailed material lives in the references/ directory (see Reference files below). Read only the reference files that apply to your task.
