A structured way to keep your design system from becoming a mess of one-off components and hardcoded values. You can audit the whole system for inconsistencies, document a component's variants and states with proper tables, or design a new pattern that actually fits what you already have. The output templates are comprehensive, covering everything from token coverage to accessibility requirements to migration paths. What I like is that it pushes you to think in terms of the system, not just isolated components. If you're maintaining a component library or trying to wrangle legacy UI code into something coherent, this gives you a repeatable process instead of reinventing documentation formats every time.
