agui-dotnet-sdk-docs

Author, update, and validate the AG-UI .NET SDK documentation pages on the docs.ag-ui.com Mintlify site (under docs/). USE FOR: adding or editing a ".NET SDK" docs page (sdk/dotnet/**/*.mdx), wiring it into the docs.json ".NET" nav group and global anchor, running the docs site locally with mintlify dev, previewing/validating rendered .NET pages, checking the .NET sidebar anchor/icon. DO NOT USE FOR: in-repo dotnet markdown such as sdks/dotnet/AGENTS.md or docs/architecture.md (use agui-dotnet-agents-sync); TypeScript/Python docs pages; product code, tests, or wire types.

agui-dotnet-server-tools

Expose server-side (backend) tools an AG-UI agent can call with the AG-UI .NET SDK — C# functions that run on the server, where the server executes the call and feeds the result back to the model. USE FOR: defining an AIFunction with AIFunctionFactory.Create and registering it on the server's IChatClient via ConfigureOptions + UseFunctionInvocation; making the model call your backend function during a run; AOT-safe tool arguments/results (registering a JsonSerializerContext for complex tool parameter types); parallel/concurrent backend tool calls (AllowConcurrentInvocation); TerminateOnUnknownCalls behavior. DO NOT USE FOR: tools that run in the client/frontend (use agui-dotnet-client-tools); pausing a tool for human approval or input (interrupts / human-in-the-loop); plain streaming chat with no tools (use agui-dotnet-streaming-chat); shared state, generative UI, multimodal, or protobuf.

agui-dotnet-shared-state

Share structured, evolving state between an AG-UI agent and its client with the AG-UI .NET SDK — the client seeds state on the request, the server reads it, mutates it, and streams the updated state back as snapshots or deltas alongside the chat. USE FOR: sending initial/working state from the client via ChatOptions.RawRepresentationFactory -> RunAgentInput.State; reading inbound state on the server with ChatOptions.TryGetRunAgentInput and RunAgentInput.State; emitting a full state object as a StateSnapshotEvent (or incremental JSON-Patch changes as a StateDeltaEvent) from a DelegatingChatClient via ChatResponseUpdate.RawRepresentation; reading state back on the client from update.RawRepresentation as StateSnapshotEvent. DO NOT USE FOR: passing one-off tool arguments (use agui-dotnet-server-tools); rendering UI components from tool calls (use agui-dotnet-generative-ui); plain chat (use agui-dotnet-streaming-chat); approvals/interrupts, multimodal, or protobuf.

agui-dotnet-transport

Add or modify a wire transport / event-stream encoding in the AG-UI .NET SDK — the protobuf codec, the SSE format, content negotiation, the JsonElement-to-protobuf Value bridge, or a brand new encoding — while preserving Native AOT compatibility and byte-level wire compatibility with @ag-ui/proto. USE FOR: working on AGUI.Formatting / AGUI.Protobuf, IAGUIEventStreamFormatter, transport content negotiation, the JsonElement-to-google.protobuf.Value bridge, SSE or protobuf framing, server formatter registration / AGUIResults.Events negotiation. DO NOT USE FOR: adding a new wire event TYPE (use agui-dotnet-wire-types), writing tests (use agui-dotnet-integration-tests).

agui-dotnet-troubleshoot

Diagnose and fix problems in an AG-UI .NET app built on the AG-UI SDK — when streaming chat, tools, state, interrupts, or the transport misbehave. USE FOR: the agent forgetting earlier turns / history truncated; update.ConversationId always null; state or lifecycle updates that never arrive; a tool throwing at runtime or producing AOT/trim warnings; an unknown-tool error mid-run; 406 Not Acceptable from the endpoint; an interrupt or approval that won't resume; and inspecting the raw AG-UI event stream (curl SSE frames, RawEvent on ChatResponseUpdate.RawRepresentation) to see what's actually on the wire. DO NOT USE FOR: first-time setup or the happy path (use agui-dotnet-streaming-chat); implementing a specific feature cleanly (use the matching agui-dotnet-* skill).

agui-dotnet-unit-tests

Author unit tests for the AG-UI .NET SDK (the *.UnitTests projects), following the SDK's serialization and compatibility conventions. USE FOR: adding unit-test coverage for a new type/method in AGUI.Abstractions/Formatting/Protobuf/Client/Server, event serialization round-trips, JsonDocument property-name assertions, backward-compatibility fixtures against TypeScript JSON, protobuf codec round-trips, client builder/handler tests, server ChatResponseUpdate conversion tests, SSE formatter tests. DO NOT USE FOR: HTTP pipeline / WebApplicationFactory end-to-end tests (use the agui-dotnet-integration-tests skill), cross-language TS↔C# server-parity tests (use the cross-language test skill).

agui-dotnet-wire-types

Add or modify a wire/protocol type in the AG-UI .NET SDK AGUI.Abstractions package — a new event, message, or content-part type, the AOT source-gen serializer context, or a polymorphic JSON converter, keeping it AOT-safe, JSON-wire-compatible with the TypeScript reference, and PublicAPI-clean. USE FOR: adding an AG-UI event type, adding a message role or input-content type, editing AGUIJsonSerializerContext, editing BaseEventJsonConverter / AGUIMessageJsonConverter / AGUIInputContentJsonConverter, fixing PublicAPI.Unshipped analyzer build failures on protocol types, wire-format round-trip serialization. DO NOT USE FOR: writing integration/SSE tests (use agui-dotnet-integration-tests), server hosting/endpoint code, or non-Abstractions packages.

agui-playwright-validate

Manually validate a running web app or docs site with the Playwright MCP server — navigate pages, assert headings/text/status, check for console errors, hover/click to exercise interactions, take screenshots for human review, and verify visual details such as an icon's color in light vs dark mode by reading computed styles. USE FOR: "validate with Playwright", "open the browser and check", visually verifying a UI or docs change, confirming a CSS/SVG/icon edit rendered, checking a page for console errors, comparing light/dark mode appearance. DO NOT USE FOR: writing automated unit/E2E test files (dojo e2e lives in agui-dojo); docs-site content/structure checks specific to the .NET SDK docs (use agui-dotnet-sdk-docs). INVOKES: browser_navigate, browser_snapshot, browser_take_screenshot, browser_evaluate, browser_hover, browser_click, browser_console_messages Playwright MCP tools.

agui-dotnet-client-tools

Expose client-side (frontend) tools to an AG-UI agent with the AG-UI .NET SDK — C# functions that run in the CLIENT app (read local state, GPS, UI, device APIs), where the client executes the call and returns the result so the run continues. USE FOR: declaring an AIFunction in the client and passing it via ChatOptions.Tools to AGUIChatClient; having the client execute a tool the model requested and feed the result back automatically; understanding why no UseFunctionInvocation is needed on the client (AGUIChatClient already invokes functions); what the server must do (UseFunctionInvocation + TerminateOnUnknownCalls) so it forwards an unknown/client tool instead of erroring. DO NOT USE FOR: tools that run on the server/backend (use agui-dotnet-server-tools); pausing for human approval/input before acting (interrupts / human-in-the-loop); plain chat (use agui-dotnet-streaming-chat); shared state, generative UI, multimodal, or protobuf.

agui-dotnet-streaming-chat

Get started with the AG-UI .NET SDK: bootstrap and run your first streaming-chat app (client + server) with the AG-UI .NET NuGet packages (AGUI.Client, AGUI.Server, AGUI.Formatting, AGUI.Abstractions). USE FOR: which packages to install and how to wire them; constructing an AGUIChatClient against an endpoint and streaming the reply as Microsoft.Extensions.AI IChatClient / ChatResponseUpdate; hosting an AG-UI POST endpoint yourself over any IChatClient; running a single- or multi-turn conversation; STATELESS agents (client owns history, resends it every turn) vs HOSTED / conversation-holding agents (server keeps the session, client pins a thread id). DO NOT USE FOR: changing the AG-UI .NET SDK itself (use the agui-dotnet-* contributor skills); server tools (agui-dotnet-server-tools); client tools (agui-dotnet-client-tools); interrupts / human-in-the-loop; shared state; generative UI; multimodal; or protobuf transport.
