Protocoles de transfert vers un humain

Quand un agent doit-il transférer la conversation ?

Détection des déclencheurs de transfert

import openai, json

client = openai.OpenAI(api_key='YOUR_OPENAI_KEY')

def should_handoff(message: str, history: list[dict]) -> dict:
    context = '\n'.join(f"{m['role']}: {m['content']}" for m in history[-4:])

        f'Conversation context:\n{context}\n'
        f'Latest message: "{message}"\n'
        f'Should this be handed to a human agent? Reasons: '
        f'angry_customer, explicit_human_request, complex_issue, legal_risk, other.\n'
        f'JSON: {{"handoff": true/false, "reason": "..."}}'
    )
    resp = client.chat.completions.create(
        model='gpt-4o-mini',
        messages=[{'role': 'user', 'content': prompt}],
        response_format={'type': 'json_object'}
    )
    return json.loads(resp.choices[0].message.content)

Transfert accompagné ou transfert à froid

Génération du résumé de la conversation
