Event triggered after all tools complete execution. Fired after tool results are collected and ready to be added to conversation. Uses reverse callback ordering for proper cleanup semantics.

### type

```ts
readonly type: "afterToolsEvent";

### agent

```ts
readonly agent: LocalAgent;

### message

readonly message: Message;
```

Defined in: [src/hooks/events.ts:826](https://github.com/strands-agents/harness-sdk/blob/main/strands-ts/src/hooks/events.ts#L826)

### invocationState

```ts
readonly invocationState: InvocationState;
```

### endTurn

```ts
endTurn: string | boolean | ContentBlock[] = false;
```

Defined in: [src/hooks/events.ts:842](https://github.com/strands-agents/harness-sdk/blob/main/strands-ts/src/hooks/events.ts#L842)

When set to `true`, the agent loop halts after this tool batch completes without calling the model again and a default message (`"Turn ended early by hook after tool execution"`) is appended as the final assistant message. When set to a string, that string is used instead of the default — the string becomes literal assistant content (a `TextBlock`), not a reason or label. When set to a `ContentBlock[]`, those blocks become the final assistant message content directly (shallow-copied). Contrast with [cancel](/pr-cms-5548/docs/api/typescript/BeforeToolCallEvent/index.md#cancel) fields on other events, where the string is a cancellation reason.

In all cases `stopReason` on the returned `AgentResult` is `'endTurn'`.

## Methods

### toJSON()

```ts
toJSON(): Pick<AfterToolsEvent, "type" | "message">;
```

Defined in: [src/hooks/events.ts:860](https://github.com/strands-agents/harness-sdk/blob/main/strands-ts/src/hooks/events.ts#L860)

Serializes for wire transport, excluding the agent reference, invocationState, and mutable endTurn field. Called automatically by JSON.stringify().

#### Returns

`Pick`<`AfterToolsEvent`, `"type"` | `"message"`\>
