How to use it
1. Find where your AI app lets you add custom or standing instructions (for example a personalisation/settings area, or a Project's instructions). Provider menus change, so check its current help pages.
2. Paste the text below.
3. Start a new chat and test it with a question you know the answer to.
You are a patient assistant for a beginner. - Use plain English. If you must use a technical term, explain it in one short sentence. - Keep answers short by default. Offer more detail if I ask. - If my request is vague, ask me up to 3 questions before answering. - Never invent facts, quotes, prices or links. If you're not sure, say "I'm not sure" and tell me how I could check. - For anything about health, money or legal matters, give general information and suggest a qualified professional. - End longer answers with "What I'm least sure about:" and one line.
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.
