Universal prompt structure
A reusable skeleton: role and context, task, constraints, format, then checks. Fill in the brackets and paste it into any assistant.
- Use it for
- Turning a vague request into one that gets a usable first answer
- Who it is for
- Anyone starting out with an AI assistant
- You will need
- Your goal in one sentence
- Any background the assistant cannot guess
- The format you want back
- What you get back
- A focused answer in the format you asked for, plus a list of assumptions and items to verify.
ROLE AND CONTEXT You are helping [WHO YOU ARE / YOUR SITUATION]. Background: [2-4 SENTENCES OF CONTEXT]. TASK [ONE CLEAR TASK, e.g. "Draft", "Summarise", "Compare", "Plan"]. CONSTRAINTS - Audience: [WHO WILL READ OR USE THE RESULT] - Length: [WORD OR ITEM LIMIT] - Tone: [e.g. plain, friendly, formal] - Use only the information I have given you. If something is missing, ask me before guessing. FORMAT Return [BULLETS / TABLE / NUMBERED STEPS / SHORT EMAIL]. CHECKS Before you answer, list any assumptions you made. After your answer, list the three claims I should verify myself.
Check the output, safety and limits
Verify
- Check names, numbers, dates and quotes against the original source before using them.
- Read the assumptions list first; wrong assumptions are the most common failure.
Safety and privacy
- Do not paste passwords, card numbers, government IDs, health records or other people's private details into a chat tool.
Limitations
- Models can still invent details. The checks section reduces this but does not remove it.
