DEDUPEDWhat do you want to do?
3 use cases
-
Add an agent with chat and generative UI to your existing app
Let your coding agent run Copilot Kit's onboarding command, which inspects your project and guides the integration.
View prompt
Help me get started with CopilotKit/CopilotKit. From the root of my project run npx --yes copilotkit@latest onboard start, follow its instructions for my <framework> app, and add one tool that renders UI.
-
Scaffold a new agent-native app in its own folder
Create a fresh Copilot Kit project without touching an app you already have.
View prompt
Scaffold a new CopilotKit/CopilotKit project with npx copilotkit@latest create for <idea>, run it locally, and add a shared state example where the agent and a component edit the same value.
-
Teach your coding agent Copilot Kit with its agent skills
Install Copilot Kit's skills so Claude Code or Codex writes correct Copilot Kit code.
View prompt
Run npx copilotkit@latest skills install, then add a human-in-the-loop confirmation step to <feature> in my CopilotKit/CopilotKit app and explain each change.

Built a Tic-Tac-Toe assistant and a 2D RPG with a LangGraph NPC using CopilotKit
Two engineers explored static, declarative and open-ended generative UI patterns and built two demos with CopilotKit: a Tic-Tac-Toe assistant and a 2D role playing game whose NPC is a LangGraph agent, using readables for game state and actions for moves.

Built a minimal CopilotKit app on Vite with a self-hosted runtime and a LangGraph agent on FastAPI
The author published a minimal working stack: CopilotKit React without Next.js on Vite, a self-hosted CopilotKit runtime on plain Node.js HTTP, and a LangGraph agent served with FastAPI, with a checklist of the AG-UI features working such as agentic chat and frontend tool execution.

Quick start with Copilot Kit
- Check you have what it needs: Node.js and npx; An existing React, Angular, Vue or React Native app, or a new one scaffolded by the CLI; An agent backend or LLM provider for the agent.
- Open CopilotKit/CopilotKit on GitHub and read the README and license.
- Open your coding agent at the root of your project
- Give it the README prompt that runs
npx --yes copilotkit@latest onboard start - Follow the onboarding instructions it prints
- Test the chat UI and one backend tool that renders UI in the client
These steps come from our top use case, Add an agent with chat and generative UI to your existing app, which also has a copy-paste agent prompt.
