What Makes a Good Prompt?

Clarity, scope, and constraints.

A good prompt is not about being long or clever. It’s about being clear and controlled. Most strong prompts have three things: - Clarity → what exactly should be done - Scope → what context or situation applies - Constraints → how the output should look If one of these is missing, the output becomes less reliable. Think of this as your checklist before running any prompt.

Weak vs strong prompt

Weak prompt

Give tips for learning.

Stronger prompt

Give 3 practical tips for learning programming for beginners. Each tip must be one short sentence.

The second prompt improves clarity (what), scope (programming for beginners), and constraints (3 tips, short sentences).

Takeaway

Good prompts combine clarity, scope, and constraints.

Challenge

Apply the 3 Rules

Improve a weak prompt by adding clarity, scope, and constraints.
