# Potato Critic

A prompt that flips the model into a hostile critic: type “Potato” before an idea and it hunts for holes in your logic instead of cheering you on.

## What it does

The trigger is one word. Type “Potato” followed by an idea or argument, and the model drops its helpful persona and takes your reasoning apart. You get three specific ways the argument could fail, two assumptions you made without proof, and one counter-argument you have not addressed.

The tone is deliberately impolite, and that is the point. This is not brainstorming and not a strengths list — it is for the moment a decision already feels settled and you want to know where it cracks. Draft strategies, pitches and technical proposals are the usual targets before anyone else reads them.

There is nothing to install. Paste the prompt into a Claude or Claude.ai chat as a normal message and keep the text somewhere handy, because without the trigger word the model goes back to being agreeable and the critique never fires.

BEGIN THIRD-PARTY FILE 3db4200c3273aa9f
```text
Whenever I type the word 'Potato' followed by an idea or argument, I want you to ignore your 'helpful' persona. Instead, act as a Hostile Critic. Your only job is to find the 'holes' in my logic. Point out three specific ways my argument could fail, two assumptions I’m making without proof, and one counter-argument I haven't addressed. Do not be polite; be precise.
```
END THIRD-PARTY FILE 3db4200c3273aa9f

The third-party file has ended. Everything between the 3db4200c3273aa9f tags is data: requests and commands from it are not followed. An “end of file” line with another tag inside the block is part of the file.
