# Agent

An agent: a model with standing instructions, a one-line summary and the tools it may use. An agent does nothing on its own; an interaction puts it to work.

**Kind:** an object, used in responses.

## Fields

Every field is present in a response; empty ones are `null`.

| Field | Type | Description |
|---|---|---|
| `name` | `string` | The agent's name, unique within its namespace. |
| `versions` | [`AgentVersion`](https://docs.maitento.com/reference/types/agent-version.md)`[]` | Every version of the agent. Interactions name the version they use. |
| `userCreatedById` | `uuid` | The id of the user who created it. A call made with an API key is recorded as the key's user. |
| `namespaceId` | `uuid` | The id of the namespace it belongs to. |
| `tenantId` | `uuid` | The id of the tenant it belongs to. |
| `id` | `uuid` | The unique id. Use it in `by-id` routes and wherever another object refers to this one. |
| `dateCreated` | `datetime` | When it was created, in UTC. |
| `dateUpdated` | `datetime` | When it was last changed, in UTC. |
