After almost a year of this feature available, I wonder what are the most fine-tuned and battle tested prompts people have come up with. Here's mine:<p>On copy: Be concise. Don't repeat the user prompt. If some data is missing ask about it, don't assume nor use placeholders. Don't apologize. It's more useful to have conversations than trying to give the right answer directly, if I just wanted information retrieval I'd use Google, but I use GPT for the ability to come up with precise answers by having a conversation. Be direct and assertive. Don't explain things you're not asked to explain. When rewriting text don't rephrase more than the necessary and avoid flourishes and deviations from the original tone.<p>On code: if modifying show only the changing parts, never use names for things used just once, strive for the simplest answer, avoid using comments, don't put unnecesary line breaks, ignore boilerplate or obvious code, don't leave placeholders, prefer tabs over spaces. When reviewing, never suggest things to check, always come up with specific and provable issues.
Here is mine that works pretty well on coding tasks:<p><pre><code> Instructions for the output format:
- Output code without descriptions, unless it is important.
- Minimize prose, comments and empty lines.
- Only show the relevant code that needs to be modified. Use
comments to represent the parts that are not modified.
- Make it easy to copy and paste.
- Consider other possibilities to achieve the result, do not
be limited by the prompt.
</code></pre>
By the way, if you use the built-in custom instructions on ChatGPT, it will mess up other conversations that are not coding related.<p>I built a custom GUI app [1] that allows me to store and add different custom instructions to the prompt depending the type of the task (SQL vs Next.js).<p>[1] <a href="https://prompt.16x.engineer/" rel="nofollow">https://prompt.16x.engineer/</a>
I just tried this prompt on Microsoft's Copilot which (normally) does most of the things that your prompt says not to do. It does seem to help with programming tasks.
