# `stream`

```elixir
@spec stream(map(), Keyword.t()) :: {:ok, map()}
```

Produces a deterministic assistant-like summary based on the first `:user_message` in `state.history`.

If the first user message contains a line starting with `Step: `, the identifier after that prefix is used; otherwise `"unknown"` is used. Returns an `{:ok, map}` shaped like a workflow provider response with `text` set to `"summary:<step>"`, empty reasoning fields, no function calls, and `finish_reason: :stop`.

## Parameters

  - state: Map containing a `:history` key with a list of message maps (each message is expected to have `:type` and `data["text"]`).
  - _opts: Unused options (kept for provider compatibility).

## Examples

    iex> Mix.Tasks.Pixir.Smoke.Workflows.EchoProvider.stream(%{history: [%{type: :user_message, data: %{"text" => "Step: alpha"}}]}, [])
    {:ok, %{text: "summary:alpha", reasoning: "", reasoning_items: [], function_calls: [], finish_reason: :stop}}
