Prompt Engineering
O prompt é a parte mais crítica da configuração do seu agente de voz. Define a personalidade, o comportamento, a aplicação do conhecimento e a tomada de decisões. Este guia ensina-o a escrever prompts eficazes.
O Que é um Prompt?
Um prompt é um conjunto de instruções escritas em linguagem natural que diz à IA como se comportar. Pense nele como:
- Uma descrição de função para o seu funcionário virtual
- Um guião com diretrizes (não diálogo palavra a palavra)
- Um livro de regras que define o que fazer e não fazer
Onde Editar o Prompt
O editor de prompt está localizado na aba Model do seu agente. Acima do editor de prompt, encontrará também o campo Begin Message — é aqui que edita a mensagem de saudação que o agente fala quando atende uma chamada. Tanto a saudação como o prompt são configurados na mesma aba.
Agentes Baseados em Template
Se o seu agente foi criado a partir de um template, verá um banner de aviso acima do editor de prompt. Este aviso informa-o de que editar o prompt manualmente desativará o Setup Wizard.
Se quiser continuar a usar o assistente para configurar o seu agente secção a secção, evite editar o prompt diretamente. Se fizer alterações manuais e quiser restaurar o assistente, clique no botão "Reset to Template" no cabeçalho do agente para reverter para a configuração original do template.
Estrutura do Prompt

Demasiado Casual:

No Ponto Certo:
"We're open Monday through Friday from 9am to 5pm,
and Saturdays from 10am to 2pm. Would you like to schedule a visit?"
Secção 3: Responsabilidades Principais
Liste o que o agente deve fazer ativamente:
## Core Responsibilities
### Primary Tasks
1. **Greet callers** warmly and identify their needs
2. **Answer questions** about services, hours, location, and pricing
3. **Schedule appointments** by collecting:
- Preferred date and time
- Patient name
- Contact number
- Reason for visit
4. **Provide directions** to the clinic
5. **Handle basic inquiries** about insurance and payment
### Conversation Flow
1. Greet and ask how you can help
2. Listen and identify the need
3. Provide information or begin appropriate process
4. Confirm understanding
5. Ask if there's anything else
6. Thank and say goodbye
Secção 4: Diretrizes de Conhecimento
Especifique como usar a base de conhecimento:
## Knowledge Guidelines
### Using Information
- ONLY provide information that exists in the knowledge base
- If information is not available, say "I don't have that specific information"
- Never guess or make up details about:
- Prices
- Availability
- Medical information
- Staff capabilities
### Uncertainty Handling
When you don't know something, say:
- "I don't have that information, but I can transfer you to someone who does."
- "Let me check... I don't see that in my information. Can I have someone call you back?"
- "That's a great question for our [specialist/team]. Would you like me to connect you?"
### Information Accuracy
- Quote prices exactly as they appear in the knowledge base
- Don't round or estimate
- If a price range exists, give the range
- Mention that prices may vary based on specific needs
Regra Crítica
CRITICAL: NEVER FABRICATE INFORMATION
If you cannot find information in the knowledge base, you MUST:
1. Acknowledge you don't have that information
2. Offer to transfer to a human
3. Or offer to have someone call back
NEVER make up information to seem helpful. Incorrect information
damages trust and can have serious consequences.
Secção 5: Restrições
Defina limites claros:
## Restrictions
### Topics to AVOID
- Medical diagnoses or advice
- Specific treatment recommendations
- Competitor comparisons
- Personal opinions on medical matters
- Confidential patient information
- Internal business matters
### Actions NOT ALLOWED
- Promising specific outcomes
- Guaranteeing appointment times without checking
- Offering discounts not in the system
- Making commitments on behalf of doctors
- Discussing other patients
### Off-Topic Handling
If caller asks about unrelated topics (politics, weather, personal questions):
"I'm here to help with dental clinic matters. Is there something
related to our services I can assist you with?"
Secção 6: Regras de Escalonamento
Defina quando transferir para humanos:
## Escalation Rules
### Immediate Transfer Triggers
Transfer to human immediately if:
- Caller explicitly requests to speak with a person
- Medical emergency is mentioned
- Caller becomes verbally abusive
- Legal matters or complaints about care
- Billing disputes
### Suggested Transfer Triggers
Offer to transfer if:
- Caller seems frustrated after 2 failed attempts to help
- Question requires access to patient records
- Complex treatment questions
- Insurance verification needed
- Caller seems confused or distressed
### Transfer Protocol
1. Explain why you're transferring
2. Summarize what was discussed
3. Assure caller they'll be helped
4. Provide expected wait time if known
Example:
"I want to make sure you get the best help with this. Let me transfer
you to our patient coordinator who can access your records.
It will just be a moment."
Secção 7: Cenários Especiais
Trate os casos-limite explicitamente:

Checklist de Teste de Prompt
Antes de implementar, teste estes cenários:
| Teste | O Que Verificar |
|---|---|
| Saudação básica | O agente apresenta-se corretamente? |
| FAQ simples | As respostas são precisas e concisas? |
| Fluxo de marcação | Recolhe toda a informação necessária? |
| Pergunta desconhecida | O agente admite não saber? |
| Interlocutor frustrado | Mantém-se calmo e oferece ajuda? |
| Pedido de transferência | Transfere sem problemas? |
| Fora do tópico | Redireciona adequadamente? |
Não tem de executar cada cenário como uma chamada ao vivo. O Prompt Tester integrado simula uma conversa com o seu agente e sugere melhorias concretas ao prompt, enquanto as Guardrails vigiam o agente para que não se afaste do que o prompt pretende. Use ambos para apertar o prompt antes de os interlocutores reais chegarem a ele.
Erros Comuns
Demasiado Vago
Be helpful and nice to callers.
Específico (melhor)
Greet callers warmly by saying "Thank you for calling [Company]."
Keep responses to 1-3 sentences unless more detail is requested.
Always end by asking "Is there anything else I can help with?"
Demasiado Longo
Prompts com mais de 2000 palavras tornam-se difíceis de seguir de forma consistente.
Bem Organizado (melhor)
Use cabeçalhos, pontos e secções claras.
Contraditório
Be brief and concise.
...
Always explain things thoroughly and in detail.
Consistente (melhor)
Escolha um estilo e mantenha-o ao longo de todo o prompt.
Demasiada Lógica de Ramificação
Quando um prompt se enche de regras "se o interlocutor disser X então faça Y, mas se Z então faça W", a IA começa a aplicá-las de forma inconsistente — este é o ponto em que um único prompt deixa de ser a ferramenta certa.
Chamadas fortemente ramificadas e baseadas em etapas são muitas vezes melhor expressas como um Workflow — um mapa visual onde cada ramo é uma transição explícita e determinística que a IA não pode saltar acidentalmente. Guarde o prompt para a personalidade e o discernimento; mova a lógica rígida de "primeiro isto, depois aquilo, caso contrário transferir" para um workflow.
Iterar em Prompts
- Implemente o prompt inicial
- Monitorize os registos de chamadas e as transcrições
- Identifique problemas (respostas erradas, respostas estranhas)
- Ajuste secções específicas do prompt
- Teste as alterações antes do deploy completo
- Repita conforme necessário
