Defined in: [src/hooks/events.ts:760](https://github.com/strands-agents/harness-sdk/blob/main/strands-ts/src/hooks/events.ts#L760)

Event emitted when an interrupt is raised during agent execution. The `interrupt.source` field discriminates between tool-callback and hook-callback origins. One event fires per unanswered interrupt at the moment the agent stops to wait for responses.

## Extends

## Constructors

### Constructor

```ts
new InterruptEvent(data): InterruptEvent;
```
