Ask what information is missing

Works with ChatGPT · Claude · Copilot · Gemini

What you’ll be able to do

You can avoid weak answers by asking AI what information is missing first.

The problem

Beginners may not know what information to provide for a strong answer.

What this skill does

Ask AI to identify missing information before completing the task.

When to use it

  • Before you finalize a decision, plan, message, or analysis.

Best for: Planning, decisions, business, research

Juni, the One AI Skill guide

Juni’s tip

When you don't know what to say, ask AI what it needs.

The prompt

Main prompt
Before you finalize this [plan, message, or decision], list: (1) the key information that's missing, (2) the assumptions you're making to fill those gaps, and (3) the risks if those assumptions are wrong. Then tell me which gaps matter most to close.

Weak vs. better

✗ Weak prompt

Help me plan an event.

✓ Better prompt

Before you plan this event, list what's missing, the assumptions you'd make about budget and guest count, and the risks if those are wrong.

Why this works

This reveals hidden assumptions and prevents AI from guessing. Seeing the assumptions and risks up front lets you catch a wrong answer before you act on it.

The move

The move: ask AI what information is missing before it answers.

Practice task

Try it now

Use this for a task where you do not know what details to include.

Self-check

  • The AI listed its assumptions, not just questions.
  • It flagged at least one risk if an assumption is wrong.
  • You can see which missing details actually change the outcome.

Common mistakes to avoid

  • Asking for the final output before checking what the AI is assuming.
  • Ignoring the assumptions list, so hidden guesses slip into your decision.
  • Treating every gap as equal instead of closing the ones that matter.
