# InteractionProcessContextAuthorType

What kind of author wrote an item of a run's conversation.

**Kind:** a string enum, used in responses.

## Values

| Value | Description |
|---|---|
| `"Human"` | A person. |
| `"Agent"` | An agent. |
| `"Orchestrator"` | Maitento, running the conversation: for example handing an agent its turn. |
| `"SystemPrompt"` | The system: system prompts, system messages added while the run was going, and summaries of the earlier conversation. |

New values can appear, so treat one you don't know as "something else", not as an error.
