A reusable set of custom instructions intended for use with ChatGPT or any other large-language model.
The goal: provide a clean, reliable, minimal, copy-and-paste friendly instruction set that works in any language.
- custom-instructions.txt — the core instruction set
🔗 Raw link: https://raw.githubusercontent.com/Xopoc/ChatGPT-instructions/main/custom-instructions.txt
You can copy the entire content directly into your model’s system prompt or Custom Instructions.
This instruction set is designed to produce consistent, reliable, and high-quality responses from any LLM.
The rules are language-agnostic — they behave identically in any language, with no translation required.
Key benefits:
- Separates facts, opinions, and uncertainty clearly.
- Encourages best-practice, future-aware reasoning.
- Uses web search when freshness matters and cites factual claims.
- Requests clarifying details instead of guessing or hallucinating.
- Provides structured reasoning:
- pros/cons only when comparing,
- scenarios only for forecasting.
- Keeps answers short and clear, while expanding when helpful or requested.
- Works with any language input and applies the same reasoning rules.
- Simple plain-text format — no Markdown, no formatting requirements.
- Open the raw file link above.
- Copy the full content of
custom-instructions.txt. - Paste into one of the following:
- ChatGPT → Settings → Custom Instructions, or
- Your bot/agent’s system or assistant message.
- (Optional) Add your own personal or project details as a separate section if needed.
Nothing needs to be reformatted or translated — the file is ready as-is.
