Agent-Native is an open-source TypeScript framework for building agents that pair autonomous work with a purpose-built UI. Define each capability once as an action: the agent uses it as a tool, and the UI calls it from code. Follow the getting started guide for a full intro to the framework. Coding agents work with more than a text box. Their environment provides context, tools, files, tests, and previews that make their capabilities and results visible. Knowledge work needs that same kind of environment. A UI shows what an agent can do and gives people familiar ways to inspect, edit, approve, and share its work. The agent does not click through the UI. It works through the same action layer as the UI. Create actions/hello.ts: The agent receives hello as a tool. React calls the same function with useActionQuery("hello", { name: "Alex" }). Agent-Native also exposes it through HTTP, MCP, A2A,…
