Google's 9 Hour AI Prompt Engineering Course In 20 Minutes

Tina Huang. Tina condenses Google's official Prompting Essentials course into the five-part TCREI structure (Task, Context, References, Evaluate, Iterate) with worked examples on each. After the article shows you five rewrites, this hands you the recipe Google itself teaches employees, so you can do the rewrite on your own prompts without copying ours.

AI Expert note

The TCREI checklist is the takeaway; pause after each worked example and redo the rewrite on one of your own prompts, the same move the article's five examples teach.

What you should get from this

You leave with the five-part TCREI structure as a repeatable checklist for building and refining your own prompts.
