# Stream + Conversation

> Stream with conversation history and handle TEXT_MESSAGE deltas without duplicating RUN_FINISHED content

Combines `Stream()` with conversation history — demonstrates event handling so you do not print the same assistant text twice (deltas vs final body).

Source: [`examples/agent_with_stream_conversation/`](https://github.com/agenticenv/agent-sdk-go/tree/main/examples/agent_with_stream_conversation)

## What it demonstrates

* `Stream` with `ConversationOptions`
* Distinguishing `TEXT_MESSAGE_CONTENT` deltas from `RUN_FINISHED` aggregate content
* Pattern for chat UIs that stream then finalize

## Key code

```go theme={null}
a, err := agent.NewAgent(
    agent.WithLLMClient(llmClient),
    agent.WithStream(true),
    agent.WithConversation(inMemoryConv),
)

eventCh, err := a.Stream(ctx, prompt, &agent.AgentRunOptions{
    ConversationOptions: &agent.ConversationRunOptions{ID: "demo"},
})
for ev := range eventCh {
    switch ev.Type() {
    case agent.AgentEventTypeTextMessageContent:
        if t, ok := ev.(*agent.AgentTextMessageContentEvent); ok {
            fmt.Print(t.Delta) // stream tokens as they arrive
        }
    case agent.AgentEventTypeRunFinished:
        fmt.Println() // newline after last delta — do NOT reprint full content
    }
}
```

This example uses in-memory conversation (no Redis required). The key pattern: print deltas on `TEXT_MESSAGE_CONTENT` and do **not** reprint `RUN_FINISHED.Result.Content` — it duplicates the streamed text.

## Run

From `examples/`:

```bash theme={null}
go run ./agent_with_stream_conversation
go run ./agent_with_stream_conversation "What is 5 * 8?"
```

## Expected output

```
5 * 8 = 40
```

Tokens print as they stream; the run exits after `RUN_FINISHED`. Run again with a follow-up — in-memory history carries context within the same process (use Redis + `conversation.mdx` for cross-process persistence).
