THE SYSTEM I NO LONGER KNOW BY HEART

Summary from the TLDR Design newsletter

Working with AI agents means the author no longer memorizes every detail of the design system they build, a shift that requires making systems legible to LLMs. That knowledge has to move into the system itself, through explicit naming, current documentation, and composition rules, since agents can't rely on informal context or unwritten history. Understanding why the system works still matters, but less inventory in the designer's head is a trade worth taking if the system knows more about itself.
