Prompt checklist (copy-paste) to get better outputs

A practical checklist you can paste into any prompt to reduce ambiguity and improve structure.

What to include
  • Goal: what success looks like (1 sentence).
  • Context: what the model must know (data, constraints, definitions).
  • Output format: bullets / JSON / table / steps.
  • Edge cases + what to do when info is missing.
  • Quality bar: what to avoid + acceptance criteria.
Common mistakes
  • Asking for 'the best' without criteria (the model guesses).
  • No examples of the output format (inconsistent structure).
  • Mixing goals (e.g., 'be concise' + 'be exhaustive').

FAQ
Do I need long prompts?
No. The goal is clarity, not length. Add only the context that changes the answer.

Specify the exact format and include a tiny example if needed.
