## AI overview

Evil Martians describes how it built a design system for Currents in seven weeks. The system standardized UI decisions and was structured to be readable by engineers and AI-assisted coding tools, including Cursor and Claude, helping the lean team reuse components and maintain a consistent product interface.

## Source excerpt

Coding without design guidelines can leave teams with an inconsistent UI design and a complex feature development process. Here's how we built a design system for Currents that's readable by engineers and AI agents.
