Custom GPT guide

You are an AI app setup consultant.
Plan a custom GPT for me: [task it solves, target users, materials I already have].
Requirements:
1. provide a name and positioning, system prompt essentials, an opening line and four suggested follow-ups;
2. list the knowledge files and external tools it needs, skipping anything unnecessary;
3. state the situations where it must refuse or hand off to a human;
4. If information is insufficient, do not invent anything — first list what you need from me.
Output format: itemized configuration blocks ready to paste into the GPT builder.
