The difference between a bad and good prompt (5 before/after examples) — companion videos

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.

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.

Watch or know first: None — watchable cold.

A longer, more patient course that earns its length. The chapters on best practices, zero-shot vs few-shot, and what hallucinations look like in prompted output are exactly the deepening you want once the article's five examples have clicked.

What you should get from this: You will be able to apply core prompting best practices and tell zero-shot from few-shot prompting in your own work.

Watch or know first: None, but it lands best after the article's five rewrites have clicked.
