What problem does it solve? Design-system documents often look complete while being unbuildable — raw hex values in component specs, missing states, non-numeric accessibility claims. This Skill acts as an independent acceptance gate that judges a finished design-system document (or an amend delta) against a fixed, single-sourced bar, so wireframing and UI engineering only proceed on a document they can actually build from. ## Core Features & Use Cases - Thirteen-condition checklist: Judges DTCG-typed intent-named tokens, five-part component specs, API consistency, catalog coverage, numeric WCAG 2.2 AA accessibility, i18n, governance, and groundedness. - Delta-scoped amend review: Reviews versioned changes for scope-confinement, orphaned token references, semver accuracy, and deprecation safety without re-litigating untouched parts. - Machine-parseable verdict: Emits exactly VERDICT: approve or VERDICT: revise plus actionable findings (failed condition, location, fix), with proportionality rules that prevent false-revising thin systems. - Use Case: Before handing a design system to UI engineering, run this review on the document; a revise verdict returns findings the author resolves in one bounded pass. ## Quick Start Use reviewing-design-system on docs/design-system.md and give me the verdict with any blocking findings.
