​
Observação sobre Consistência nos Nomes

Os nomes utilizados nos seus arquivos YAML (agents.yaml e tasks.yaml) devem corresponder aos nomes dos métodos no seu código Python. Por exemplo, você pode referenciar o agente para tarefas específicas a partir do arquivo tasks.yaml. Essa consistência de nomes permite que a CrewAI conecte automaticamente suas configurações ao seu código; caso contrário, sua tarefa não reconhecerá a referência corretamente.

​
Exemplos de Referências

Observe como usamos o mesmo nome para o agente no arquivo agents.yaml (email_summarizer) e no método do arquivo crew.py (email_summarizer).

agents.yaml
email_summarizer:
    role: >
      Email Summarizer
    goal: >
      Summarize emails into a concise and clear summary
    backstory: >
      You will create a 5 bullet point summary of the report
    llm: provider/model-id  # Add your choice of model here

Observe como usamos o mesmo nome para a tarefa no arquivo tasks.yaml (email_summarizer_task) e no método no arquivo crew.py (email_summarizer_task).

tasks.yaml
email_summarizer_task:
    description: >
      Summarize the email into a 5 bullet point summary
    expected_output: >
      A 5 bullet point summary of the email
    agent: email_summarizer
    context:
      - reporting_task
      - research_task
