Structure

Role → context → task → format → constraints → examples. Never skip the format line.

Templates

Blog post, email, plan, summary, code review. Save each and re-use them.

Habits

• Iterate — not restart
• Ask the model to critique its own answer
• Give one great example before asking for volume

Common mistakes

• 'Write X' with no context
• Vague voice descriptions
• Skipping the constraints line

Practical example

A single 'You are... Write... Return as bulleted list... Under 200 words' template lifted a marketing team's usable-first-draft rate from 30% to 80%.

FAQ

Does model choice matter?

Less than prompt structure. A great prompt on GPT-4o class model beats a bad prompt on the flagship.
