# Policy Implementation Code

## Conversation Content Boundaries

```typescript
const CONVERSATION_POLICY = {
  blockedTopics: [
    'medical advice', 'legal advice', 'financial advice',
    'political opinions', 'competitor pricing'
  ],
  requiredDisclosures: [
    'This is an AI assistant',
    'This call may be recorded'
  ],
  maxCallDuration: 600,  // 10 minutes
  escalationTriggers: ['speak to a human', 'talk to manager', 'real person']
};

function enforceContentPolicy(agentResponse: string): string {
  for (const topic of CONVERSATION_POLICY.blockedTopics) {
    if (agentResponse.toLowerCase().includes(topic)) {
      return "That topic requires a specialist. Transferring now.";
    }
  }
  return agentResponse;
}
```

## Call Recording Consent

```typescript
const CONSENT_SCRIPT = {
  opening: "Hi, this is an AI assistant calling from [Company]. This call may be recorded for quality purposes. Is that okay?",
  noConsent: "Understood. Continuing without recording. How may we assist today?",
  consentReceived: true
};

app.post('/retell-webhook', async (req, res) => {
  const { call_id, turn_number, transcript } = req.body;

  // First turn: always deliver consent disclosure
  if (turn_number === 0) {
    return res.json({ response: CONSENT_SCRIPT.opening });
  }

  // Second turn: check for consent
  if (turn_number === 1) {
    const consented = /yes|okay|sure|that's fine/i.test(transcript);
    if (!consented) {
      await retell.call.update(call_id, { recording_enabled: false });
      return res.json({ response: CONSENT_SCRIPT.noConsent });
    }
  }

  // Normal processing
  const response = await generateResponse(req.body);
  return res.json({ response: enforceContentPolicy(response) });
});
```

## Cost Controls

```typescript
class CallCostPolicy {
  private activeCalls = new Map<string, number>();
  private maxConcurrent = 10;
  private maxDurationSec = 600;
  private dailyBudget = 100;  // dollars
  private costPerMinute = 0.10;

  canInitiateCall(): boolean {
    if (this.activeCalls.size >= this.maxConcurrent) return false;
    if (this.getDailySpend() >= this.dailyBudget) return false;
    return true;
  }

  monitorDuration(callId: string) {
    const started = this.activeCalls.get(callId);
    if (started && (Date.now() - started) / 1000 > this.maxDurationSec) {
      return { action: 'end', reason: 'Maximum call duration exceeded' };
    }
    return { action: 'continue' };
  }

  getDailySpend(): number {
    let totalMinutes = 0;
    for (const started of this.activeCalls.values()) {
      totalMinutes += (Date.now() - started) / 60000;
    }
    return totalMinutes * this.costPerMinute;
  }
}
```

## Human Escalation Triggers

```typescript
function checkEscalation(transcript: string): boolean {
  const triggers = ['speak to a human', 'real person', 'talk to someone', 'supervisor', 'manager'];
  return triggers.some(t => transcript.toLowerCase().includes(t));
}
```

## Policy Dashboard

```typescript
const dashboard = {
  activeCalls: costPolicy.activeCalls.size,
  dailySpend: costPolicy.getDailySpend().toFixed(2),
  escalationRate: metrics.rate('escalations'),
  avgCallDuration: metrics.avg('call_duration_sec')
};
```
