How to pass in result from one AI assistant to the next?

[philmetzger]

I have the following use case:

• I use ai with user input to generate a project scope.
• I then take that scope and pass it into another ai to generate clarifying questions.

This means I call the ai twice in a server action. One after the other.
Is this the correct way of doing it? Or should I use a tool?

Basically how can i pass in the reply from ai into the next AI.

const messagesArray: { role: any; content: string }[] = [];
  messagesArray.push({ role: 'assistant', content: scopeFromAI });

  aiState.update((messages: ServerMessage[]) => [...messages, { role: 'system', content: systemPrompt }]);

  const result = await generateObject({
    model: anthropic('claude-3-5-sonnet-20240620'),
    messages: messagesArray,
    system: systemPrompt,
    schema: z.object({
      clarifyingQuestions: z
        .array(z.string().describe('A detailed q'))
        .describe('List of questions that would help clarify the scope. Max 5 questions.'),
    }),
  });

Because i get an error
