A collection of opinionated constraints meant to guide AI agents when they're building user interfaces. Think of it as guard rails for consistent UI decisions rather than a component library or framework. The "evolving" part suggests this is actively maintained with lessons learned from real agent outputs. You'd reach for this when you want Claude to follow specific patterns and conventions while generating UI code, especially if you're tired of explaining the same design decisions repeatedly. The source repository is fairly minimal, so expect practical constraints rather than comprehensive documentation. Worth trying if you're doing repeated UI generation work and want more consistency.
