About a2ui-renderer

a2ui-renderer
Render A2UI (Agent-to-UI declarative surfaces) in CopilotKit v2
a2ui-renderer is an agent skill from the CopilotKit project's skills collection, listed on skills.sh. It shows how to render A2UI, the agent-to-UI declarative surfaces format, in CopilotKit v2. A2UI has two halves. On the runtime side, the server declares the a2ui middleware when it creates CopilotRuntime, which is shown in the example route file api.copilotkit.$.tsx. On the client side, the provider enables the a2ui prop. Once both are set, the /info endpoint reports that A2UI is available, and the client mounts createA2UIMessageRenderer automatically, so the developer does not need to wire renderActivityMessages by hand. The skill builds on the CopilotKit react-core and runtime skills, which should be read first for the basics of the provider and runtime. It is for developers who are adding agent-driven interface surfaces to a CopilotKit app built on React and a server runtime.
