AI Agents Should Have an Undo Button

If an AI agent does something wrong, you should be able to undo it fast.

The big idea

Did you know good AI agents come with an undo button? If AI sends a wrong email or moves a file by mistake, you should be able to take it back. No undo = scary AI.

Some examples

Email apps with 'unsend' help when AI helps write.
AI that moves files should keep a backup.
Game AIs should let you reset the level.
Real undo > fake 'are you sure?' prompts.

Try it!

List 3 things in your house an AI agent shouldn't do without undo.

How to do it well

Good the undo button with AI follows a pattern. First, tell the AI exactly what you want and what you have to work with. Then read what it gives you carefully. If something looks off, ask it to fix that one thing. You are the boss — the AI is the helper.

A simple step-by-step

Before any big change, ask: 'Can I undo this if it goes wrong?'
If yes — go ahead, but pay attention.
If no — slow down and double-check.
Save a copy of the OLD version when possible.
Tell someone what you changed, in case YOU forget.

Common mistakes to avoid

Treating sent messages as undoable — they aren't.
Treating posted pictures as undoable — once shared, copies exist.
Treating spent money as undoable — most stores won't refund.
Trusting that 'the AI will fix it' if you mess up.

Why this is a real skill

Engineers call this 'reversibility.' Knowing what you can undo and what you can't is core safety thinking — the same thinking pilots and surgeons use.
