Set the post-prompt text for summary generation. After a conversation ends, the AI
uses this prompt to analyze the conversation and generate a structured summary. The
summary is delivered to your [`onSummary()`][on-summary] callback or
the [`setPostPromptUrl()`][set-post-prompt-url] endpoint.

## **Parameters**

<ParamField path="text" type="string" required={true} toc={true}>
  Instructions for summary generation. Tell the AI what to extract from the
  conversation -- for example, caller intent, resolution status, or action items.
</ParamField>

## **Returns**

[`AgentBase`][ref-agentbase] -- Returns `this` for method chaining.

## **Example**

```typescript {5}
import { AgentBase } from '@signalwire/sdk';

const agent = new AgentBase({ name: 'support', route: '/support' });
agent.setPromptText('You are a customer support agent for Acme Corp.');
agent.setPostPrompt(`
Summarize this conversation as JSON with the following fields:
- caller_intent: What the caller wanted
- resolution: Whether their issue was resolved (yes/no/partial)
- action_items: List of follow-up actions needed
- sentiment: Overall caller sentiment (positive/neutral/negative)
`);
await agent.serve();
```
