> The Task Verbs escalate, next, return as typed SDK methods, with inputs, result, refusals and an example.

Reference for [Task](/business/nouns/task), one group of [Task methods](/code/sdk/task).

### Task.escalate
Escalate moves a Task to the Role its current Role escalates to, with the reason attached. [Verb page](/business/nouns/task/escalate?interface=sdk).

```ts
interface TaskVerbs {
  escalate(input: TaskEscalateInput, options?: SB.CallOptions): SB.Call<Task>
}
```

Emits [`Task.escalated`](/business/events/Task.escalated).

**Inputs**

| Input | Type | Required | Description |
| --- | --- | --- | --- |
| `task` | [Task](/business/nouns/task) | Yes | The Task to escalate. |
| `reason` | `text` | Yes | Why the current Role cannot finish it. |

**Returns**

| Output | Type | Required | Description |
| --- | --- | --- | --- |
| `task` | [Task](/business/nouns/task) | Yes | The Task, assigned upward. |

**Refuses when**

| Check | Error | Fix | Then call |
| --- | --- | --- | --- |
| The key is valid, but its scopes do not allow this operation. | [`forbidden`](/code/api/errors/forbidden) | Use a key whose scopes cover the operation, or ask an owner of the namespace to grant them. | None. |
| The record is not in a state that allows this Verb, so the call is refused. | [`refused`](/code/api/errors/refused) | Read the record, run the Verb that moves it to an allowed state, then retry. | None. |

**Example**

```ts
import { $ } from 'startup-builder'

const task = await $.Task.escalate({ task: 'task_tVPKjporKn', reason: 'Example reason' })
```

### Task.next
Next returns the oldest open Task the calling Worker’s Roles may claim, without claiming it. [Verb page](/business/nouns/task/next?interface=sdk).

interface TaskVerbs {
  next(input?: TaskNextInput, options?: SB.CallOptions): SB.Call<Task>
}
```
