+# AG-UI Go Example Server
+
+This example is a Fiber v3 AG-UI server for local development and Dojo testing.
+It replaces the older minimal `/agentic` example with a broader route surface
+based on the Go Dojo server example.
+
+## Run
+
+Requires Go 1.25 or newer. Fiber v3.3.0 requires Go 1.25, so `go mod tidy`
+updates this example module to `go 1.25.0`.
+
+```bash
+cd sdks/community/go/example/server
+OPENAI_API_KEY=... go run ./cmd
+```
+
+The default server address is `http://127.0.0.1:8080`.
+
+The server uses the reproducible `MODEL_PROVIDER=openai` path from
+`github.com/cloudwego/eino-ext/components/model/openai`. Prototype-only provider
+and tool dependencies from the standalone source were removed for this monorepo
+example. The read-only `file_read` tool is implemented locally in
+`internal/agent/tools.go`.
+
+## Environment
+
+| Variable | Default | Description |
+| --- | --- | --- |
+| `HOST` | `127.0.0.1` | Server bind host. |
+| `PORT` | `8080` | Server port. |
+| `MODEL_PROVIDER` | `openai` | Only `openai` is supported in this monorepo example. |
+| `MODEL` | `gpt-4o` | Model passed to the OpenAI Eino provider. |
+| `OPENAI_API_KEY` | unset | Required for model-backed routes and multimodal helper clients. |
+| `AGENT_WORKSPACE` | process working directory | Read-only root for the `file_read` tool. Set it deliberately. |
+| `AGENT_AUTO_APPROVE` | `false` | Bypass the approval interrupt path for `/agentic`. |
+| `AGENT_MAX_ITERATIONS` | `8` | Model/tool loop iteration budget. |
+| `CORS_ENABLED` | `true` | Permissive CORS for local UI development. |
+| `AGENTIC_UI_PACE_MS` | `600` | Step delay for `/agentic_generative_ui`. |
+
+## Routes
+
+| Route | Notes |
+| --- | --- |
+| `GET /` | Health/config metadata and route list. |
+| `POST /agentic` | Primary read-only agent loop. |
+| `POST /agentic_chat` | Dojo frontend-tools chat route. |
+| `POST /backend_tool_rendering` | Dojo route alias using the frontend-tools chat posture. |
+| `POST /human_in_the_loop` | Approval route. `X-AG-Approval: off` or `?approval=off` disables the approval gate. |
+| `POST /agentic_generative_ui` | Deterministic multi-step generative UI route. |
+| `POST /tool_based_generative_ui` | Client-tool generative UI route. |
+| `POST /shared_state` | Recipe shared-state route. |
+| `POST /predictive_state_updates` | Document predictive state updates route. |
+| `POST /agentic_chat_multimodal` | Multimodal-capable chat route using the OpenAI provider path. |
+| `POST /image-gen` | OpenAI image generation helper. |
+| `POST /vision` | OpenAI vision helper. |
+| `POST /audio` | OpenAI audio transcription helper. |
+| `POST /document` | OpenAI document analysis helper. |
+
+All `POST` routes accept AG-UI `RunAgentInput` JSON unless noted by their
+specific handler. SSE responses use the AG-UI event stream format.
+
+## Dojo
+
+Run this server separately and configure Dojo to point the relevant integration
+runtime URL at `http://127.0.0.1:8080`. This server lives under the Go SDK
+examples rather than an `integrations/.../examples` package, so it is not
+automatically registered as a first-class Dojo integration by this change.
+
+## Go Client
+
+The Go example client default endpoint is aligned with this server:
+
+```text
+http://localhost:8080/agentic
+```
+
+Pass an explicit endpoint to the client if you run the server on a different
+host or port.
+
+## Verification
+
+```bash
+cd sdks/community/go/example/server
+gofmt -w ./cmd ./internal
+go mod tidy
+go test ./...
+go test ./... -run 'Test.*Route|Test.*App|Test.*SSE'
+rg -n 'github.com/mattsp1290/ag-ui-go-server-example|/Users/punk1290/git|v0.0.0-00010101000000-000000000000' go.mod go.sum cmd internal
+```
+
+Credentialed model calls require `OPENAI_API_KEY`; integration tests that need
+it skip when the variable is unset.
