One card to remember the universal prompt structure-beginners stop staring blankly at the dialog box.

The Universal Prompt Formula

Role + Task + Format + Constraint = a usable prompt

  • Role: Who the AI plays ("You are a senior copy editor")-decides perspective and expertise
  • Task: What to do ("Rewrite this passage to be conversational")-verb must be specific
  • Format: What the output looks like ("under 200 words / table / bullet points")-saves rework
  • Constraint: Where the boundaries are ("don't change facts / don't embellish")-prevents drift

Three Common Faceplants

  • Task without role: AI answers in "generic support tone"-mediocre and pointless
  • No format: AI wings it, you have to re-organize
  • No constraint: AI easily overreaches, adding things you never said
