How to get Claude to write its own project instructions

My method for creating repeatable writing systems

AI struggles to maintain consistency across sessions without clear structural guidelines.

You find yourself explaining the same format requirements over and over. Each new chat means starting from scratch with your preferences.

Today's technique changes that by converting any example into reusable project instructions.

Project Instructions = The permanent blueprint for how AI structures your content. Think formatting rules, section order, and output requirements that live in your AI project forever. Write once, use infinitely. You can also think of it as the system prompt vs the user message.

Here’s how you can get Claude to write its own project instructions

There are two ways to create project instructions for your AI projects.

You can write them manually from scratch. Or you can have Claude generate the first draft for you.

My approach is to start with Claude-generated instructions as my foundation.

Then dig into the details myself. Add sections that matter to my use case or brand. Remove what doesn't fit. Test and iterate until it's perfect.

This prompt gives you that critical first draft to build from.

The generated version often gets you 70% there instantly.

Your customization makes it 100% yours. This combination beats starting from scratch every time.

The technique I created will draft you multi-page instructions instantly.
