It is no wonder that Claude Design roll out with the idea that people need to import their own design system.

LLMs can excel at small modular tasks, such as structuring content and building components with constraints.

That said, to ensure consistency and customization, designer still needs to be involved in overseeing the initial steps of the design system.

This include deciding on visual direction, writing specs, testing compliance level and oversee governance.

Even with design system available, it is highly unlikely that LLMs can produce large volume of work without burning through high amount of tokens (aka money), much less quality work.
