Why this level
- The skills hold instructions for the agent and run nothing themselves.
Install
- Works in

What it does
The AG-UI protocol repository, which connects agents to application front ends, ships two sets of developer skills. The ag-ui-dotnet plugin from the `ag-ui` marketplace holds nine skills for the .NET SDK: streaming chat, server and client tools, approvals and pauses for input, shared state, multimodal messages, reasoning traces, protobuf transport and troubleshooting. A separate `ag-ui-a2ui-integration` skill in the `skills/` folder adds A2UI rendering to an AG-UI app. It picks a mode (fixed or dynamic schema), shows how to wire the middleware and a component catalog, and lists checks for the stream at each step.
Who it is for. Developers on .NET and TypeScript who build agent front ends on AG-UI and ask Claude Code or Copilot to write the client and server.
Good fit when
- A .NET app needs streaming chat between client and server over AG-UI.
- An agent tool must wait for user approval and resume after the answer.
- A2UI surfaces are being added to an existing AG-UI app.
- Agent and client state is synchronized with snapshots and deltas.
Not a fit when
- The app does not use AG-UI and the protocol is only under evaluation.
- Skills for an SDK in another language are needed: the plugin covers .NET.
- The task concerns A2UI renderer internals outside an AG-UI app.
Example request
Add AG-UI streaming chat to this .NET server app and a tool that waits for my approval before it runs.Limitations
The marketplace holds a single plugin, ag-ui-dotnet at version 0.1.0, and it covers only the .NET SDK. The A2UI skill points to the repository CLI and integration sources, so check flag names against current code. The `.github/skills` folders serve AG-UI development itself and are not meant for users. Marketplace install is documented for Claude Code and GitHub Copilot CLI; other agents need the plugin attached manually from the plugin directory. The skills supply workflows and references: the developer still runs the build and tests of the resulting code.
How to disable. Remove the plugin through `/plugin` in Claude Code or delete the skill from the agent skills folder. The `ag-ui` marketplace can be removed separately.
FAQ
How do I install the AG-UI plugin in Claude Code?
Run `/plugin marketplace add ag-ui-protocol/ag-ui`, then `/plugin install ag-ui-dotnet@ag-ui`. GitHub Copilot CLI uses the same steps through `copilot plugin`.
Which skills does ag-ui-dotnet include?
Nine: streaming chat, server and client tools, human-in-the-loop, shared state, multimodal messages, reasoning, protobuf and troubleshooting.
What is the A2UI skill for?
It adds A2UI rendering to an AG-UI app: it picks the schema mode, wires the middleware and component catalog, then verifies the event stream.
Does the plugin work with Cursor?
The plugin README documents only Claude Code and GitHub Copilot CLI. For other agents, install from a local checkout by pointing at the plugin directory.
Which frameworks have CLI flags in the A2UI skill?
The skill lists flags for ADK, LangGraph in Python and JavaScript, CrewAI Flows, Mastra, Pydantic AI, LlamaIndex, Agno and AG2. Strands has no flag, so use its integration docs.
