1

Open the GPT Builder

In ChatGPT, click your profile icon, then select My GPTs, then Create a GPT. Switch to the Configure tab for full control.
2

Name your GPT and write instructions

Give your GPT a clear, task-specific name. In the Instructions field, paste the brief from your Agent Idea Generator — or write your own using this structure:
3

Add a knowledge source

Upload a reference file in the Knowledge section (PDF, Word, or CSV). If you are on a ChatGPT Team or Enterprise plan, you can also connect Google Drive or Slack natively via the Connections setting.
4

Add a conversation starter

Write one starter that shows users exactly how to give the GPT the information it needs. A good starter models the input format, not just the topic.
5

Test and save

Click Preview and send the GPT a real task from your work. If the response is off in format, length, or tone — adjust the Instructions and test again. Save when you are happy with the result.
You have completed this challenge when you have a saved Custom GPT that responds correctly to a real task from your work and has at least one useful conversation starter.
