What problem does it solve?
Design consultation: understands your product, researches the landscape, proposes a
complete design system (aesthetic, typography, color, layout, spacing, motion), and
generates font+color preview pages. Creates DESIGN.md as your project's design source
of truth. For existing sites, use /plan-design-review to infer the system instead.
Use when asked to "design system", "brand guidelines", or "create DESIGN.md".
Proactively suggest when starting a new project's UI with no existing
design system or DESIGN.md. (gstack)
