Set Constraints and Tone

Principle: Constraints are limits you place on the answer — length, tone, reading level, what to include or avoid. They keep the output on target.

Length and structure

• "In no more than 50 words"
• "Exactly 5 bullet points"
• "One short paragraph"

Tone and audience

Tell it what to avoid

Negative constraints are just as useful as positive ones:

• "Do not use technical jargon"
• "Avoid clichés and filler"
• "Do not include an introduction; start with the steps"

Keep constraints realistic

Too many rules at once can conflict and confuse the model. Start with the two or three that matter most, then refine.

💡 Tip: "start directly with the answer, no preamble" is a great constraint for cutting the fluff many AIs add at the start.
