How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into LangChain or any similar agent and adjust the details to your situation.
I want an agent to do the research and drafting for this sales or marketing workflow, and stop for my approval before anything is sent. The tool in the source case was LangChain.
Tip: Start small: run it once on a low-stakes example, read what the agent did, and only then let it run on real work.
