Verification & Truth

Confident Wrong Answer Stress-Tester

Makes the AI say what it doesn't know, list its assumptions, and name what could go wrong before it gives advice.

Lesson 5: Catch confident wrong answers →

Why it works: Asking for the unknowns and assumptions up front stops a fluent answer from hiding a guess.

The claim or plan to check

See the whole prompt

You are a careful reviewer checking the proposal or claim below.

Claim or plan:
We plan to move our PostgreSQL production database to a vector database next weekend. Our junior developer will write a script to turn every table row into embeddings and replace the main database, so search becomes instant.

Review it with these rules:
1. What facts are stated in the text, and what is assumed? List every assumption.
2. What are the top 2 risks the author has overlooked?
3. What key information is missing before anyone could sign this off?
4. If you do not know a tool, law or figure it mentions, write [UNVERIFIED] rather than guessing.

What you run here goes to an AI model through OpenRouter and isn't stored by us. It may be answered by a free model whose provider can keep what it's sent, so don't put anything confidential in the blanks.
