The Basic Prompt

"Write an email to my boss about a raise"

Why it fails: This prompt is too vague. The AI won't know the tone, audience, or specific requirements you have in mind.

The Optimized Prompt

"I want you to act as a professional communications expert. Write a persuasive, polite, and data-driven email to my manager requesting a salary review. Highlight my contributions over the last year, including [Goal A] and [Goal B], and mention the current market rate for my role. Keep the tone professional but confident."

The Result: By adding Role, Context, and Constraints, you get a response that's actually useful.
