Prompt Engineering Resources

Last updated: March 2, 2026

You don't need to be a Prompt Engineer; you can create your own Gemini Gem to be that for you. In this example we will look at how to create one in Gemini but the same can be achieved in other tools like ChatGPT using their Custom GPTs feature.

Steps:

  1. Create a new Gem called "Prompt Builder" (or whatever you’d like)

  2. Add the "Prompt Engineering_v7.pdf" book as "knowledge" (book attached below)

  3. Add the instructions below (or modify them as you wish)

  4. Save!

After following these steps, you can now use your personal Prompt Engineer:
