# onSummary

> Handle post-prompt summaries generated after a conversation ends.

[set-post-prompt]: /docs/server-sdks/reference/typescript/agents/agent-base/set-post-prompt

[set-post-prompt-url]: /docs/server-sdks/reference/typescript/agents/agent-base/set-post-prompt-url

Lifecycle hook invoked when a post-prompt summary is received after a conversation
ends. Override this method in a subclass to process summaries -- for example, saving
them to a CRM, triggering follow-up workflows, or logging call outcomes.

A post-prompt must be configured via
[`setPostPrompt()`][set-post-prompt]
for summaries to be generated.

> **Note**
>
> The default implementation does nothing. You must override it in a subclass or set a
> [`setPostPromptUrl()`][set-post-prompt-url]
> to receive summaries at an external endpoint.

## **Parameters**

**`summary`** `PostPromptData | null` — required

The summary object generated by the AI based on your post-prompt instructions.
`null` if no summary could be extracted from the response.

---

**`rawData`** `PostPrompt` — required

The complete raw POST data from the post-prompt request, including metadata
like `call_id` and the full AI response.

---

## **Returns**

`void | Promise<void>`

## **Example**

```typescript {15}
import { AgentBase } from '@signalwire/sdk';

class SupportAgent extends AgentBase {
  constructor() {
    super({ name: 'support', route: '/support' });
    this.setPromptText('You are a helpful customer support agent.');
    this.setPostPrompt(`
      Summarize this call as JSON:
      - intent: caller's primary intent
      - resolved: yes/no/partial
      - sentiment: positive/neutral/negative
    `);
  }

  override async onSummary(
    summary: Record<string, unknown> | null,
    rawData: Record<string, unknown>,
  ): Promise<void> {
    if (summary) {
      const callId = (rawData.call_id as string) ?? 'unknown';
      console.log(`Call ${callId} summary:`, summary);
      // await saveToDatabase(callId, summary);
    }
  }
}

const agent = new SupportAgent();
await agent.serve();
```
