const prompt = await pull("jacob/joke-generator");
const formattedPrompt = await prompt.invoke({
  topic: "cats",
});

const { system, messages } = convertPromptToAnthropic(formattedPrompt);

const anthropicClient = new Anthropic({
  apiKey: 'your_api_key',
});

const anthropicResponse = await anthropicClient.messages.create({
