AI Agent Support

I am creating a workflow that is going to pull news articles from two rss feeds. I want to feed the feeds into an AI agent (who will be connected to chat GPT) - How do i build out instuctions or a prompt in the ai agent to ensure it takes that data and puts it into a google doc with the correct tone of voice etc. I have 90% of the workflow done but I am struggling to get it over the finishing line. Any help would be appreciated

##Error = N/A

Please share your workflow

Share the output returned by the last node

well how are you inputting the articles to the bot? Cause that workflow is currently not reciving anything and there is no tool call.
