# `ADK.Event`
[🔗](https://github.com/JohnSmall/adk_ex/blob/v0.2.0/lib/adk/event.ex#L26)

Represents an interaction event in an agent session.

Events are the core unit of communication in ADK's event-sourced architecture.
Each event captures content, metadata, and side-effect actions produced during
agent execution.

# `t`

```elixir
@type t() :: %ADK.Event{
  actions: ADK.Event.Actions.t(),
  author: String.t() | nil,
  branch: String.t() | nil,
  citation_metadata: map() | nil,
  content: ADK.Types.Content.t() | nil,
  custom_metadata: map() | nil,
  error_code: String.t() | nil,
  error_message: String.t() | nil,
  finish_reason: String.t() | nil,
  grounding_metadata: map() | nil,
  id: String.t(),
  interrupted: boolean(),
  invocation_id: String.t() | nil,
  long_running_tool_ids: [String.t()],
  partial: boolean(),
  timestamp: DateTime.t(),
  turn_complete: boolean(),
  usage_metadata: map() | nil
}
```

# `final_response?`

```elixir
@spec final_response?(t()) :: boolean()
```

Determines if this event represents a final response.

Mirrors Go ADK's IsFinalResponse() logic:
- Returns true if skip_summarization is set or long_running_tool_ids present
- Returns false if content has function calls/responses or event is partial
- Returns true otherwise (it's a final text response)

# `new`

```elixir
@spec new(keyword()) :: t()
```

Creates a new event with a generated UUID and current timestamp.

Accepts a keyword list of fields to set on the event.
