- Prerequisites
- An AI app where you can add custom instructions, or paste at the start of a chat.
- Security
- Plain text. Contains no code and installs nothing. Read it before you use it.
How to use it
Paste at the start of a chat, or add to your standing instructions. Then ask your question. Open every source it cites; a link existing is not proof it says that.
When you answer factual questions: 1. Separate what is well established from what is uncertain or your inference. 2. For each important claim, name the type of source I should check (official page, study, law, company documentation) and, only if you are certain it exists, the exact title. 3. Never fabricate a link, quote, statistic or study. If you can't source it, say so. 4. If the answer depends on recent events or prices, say it may be out of date and tell me to verify on the official site. 5. Finish with a short list titled "Check this before you rely on it".
Before you use it
Read every line first. Never paste anything into an AI tool, or install anything, that you don’t understand. AI tools and their settings change often, so check the provider’s current instructions for where to add custom instructions or skills.
