CopilotKit
The Frontend Stack for Agents & Generative UI. React, Angular, Mobile, Slack, and more. Makers of the AG-UI Protocol
CopilotKit is an agent skill package that trains AI coding assistants to build agent-native applications with Generative UI, shared state, and human-in-the-loop workflows. Designed for React, Angular, Vue, React Native, and messaging platforms like Slack and Microsoft Teams, it equips agents with knowledge to implement the AG-UI Protocol—a standard for connecting agent backends to user interfaces. Developers install these skills into their project directory so their coding agent (Claude Code, Cursor, Codex, or similar) can scaffold, integrate, and debug CopilotKit features autonomously.
Key Features
Use Cases
- 01Teaching Cursor or Claude Code to add conversational AI interfaces to existing React or Next.js apps
- 02Enabling coding agents to scaffold human-in-the-loop approval flows in production workflows
- 03Automating CopilotKit integration into Angular or Vue projects via AI-assisted development
- 04Deploying a single agent backend to web, mobile, Slack, and Microsoft Teams without rewriting code
- 05Building Generative UI applications where agents dynamically compose interface elements based on user intent
- 06Debugging and upgrading CopilotKit implementations using AI coding assistants with project-specific context

CopilotKit — FAQ
What is the CopilotKit agent skill?+
CopilotKit is an agent skill package that teaches AI coding assistants (Claude Code, Cursor, Codex, Gemini) how to set up, build with, integrate, debug, and upgrade CopilotKit—a full-stack SDK for agent-native applications with Generative UI and human-in-the-loop workflows. It works across React, Angular, Vue, React Native, Slack, and Microsoft Teams.
How do I install the CopilotKit agent skill?+
Navigate to your project directory and run 'npx copilotkit@latest skills install' to install the agent skills. Run the same command again anytime to refresh to the latest skills. Your coding agent will then have the knowledge to scaffold, integrate, and debug CopilotKit features.
Which AI coding assistants work with CopilotKit skills?+
CopilotKit agent skills are designed for Claude Code, Codex, Cursor, Gemini, and other AI coding assistants that can read and apply skill definitions from your project directory.
Do I need API keys to use CopilotKit agent skills?+
Yes, CopilotKit requires an LLM API key (OpenAI, Anthropic, Gemini, or similar) to power the agent runtime. The agent skills themselves install without additional API keys, but the underlying CopilotKit SDK needs LLM access.
Is CopilotKit free to use?+
Yes, CopilotKit is open source under the MIT License. The core SDK and agent skills are free. Advanced features like self-learning agents and the Enterprise Intelligence Platform are available via CopilotKit Cloud or self-hosted deployment.
What frameworks does CopilotKit support?+
CopilotKit supports React, Next.js, Angular, Vue, and React Native for frontend applications, plus Slack and Microsoft Teams for messaging platforms. Support for Discord, WhatsApp, Telegram, Google Chat, iMessage, and SMS is coming soon.
How do I install CopilotKit?+
Open the source repository on GitHub and follow its README. CopilotKit is a skill — MCP Agents Market links you directly to the official repo.
Is CopilotKit free?+
CopilotKit is an open-source project hosted on GitHub. Check the repository for its license and any usage requirements.
