design-qa
Set up or run design QA gates — token + hardcoded-value lint, automated a11y (axe), contrast, visual regression across variants/states/themes/RTL, and the manual a11y checklist. Use when the user wants CI quality gates, to prevent design regressions, or to QA a component/screen before shipping.

# Skill: Design QA Stand up the automated + manual gates that stop quality from regressing. ## Steps 1. Read `workflows/design-qa.md` (the QA pyramid: token/lint gates → automated a11y → visual regression → manual a11y). 2. Wire the **fast gates** first (every commit/PR): `python3 scripts/validate_tokens.py`, `python3 scripts/validate_contrast.py` (batch WCAG over the token pairs), and `python3 scripts/lint_hardcodes.py <src>` (no raw hex/px/timing in component code). The repo's `.github/workflows/ci.yml` runs these. 3. Add **automated a11y** (axe-core / Pa11y) over each component's states (error/loading/disabled/expanded/selected), zero serious/critical to merge. Run the **real-render contrast gate** `node scripts/measure_render.mjs <file.html>` (and `--dark`) — it opens the page in headless Chromium, disables transitions, and measures the true computed-style + alpha-composited contrast of every text element (catches what static token checks miss). 4. Add **visual regression** snapshots across variants × sizes × states × light/dark + key breakpoints + RTL; freeze animations + deterministic data. 5. Sign off the **manual a11y** checklist per release (keyboard, screen reader, 400% reflow, 200% text-spacing, reduced-motion, forced-colors — `accessibility/*`). ## Verification (definition of done) - An unreviewed PR cannot introduce an unresolved token alias, a contrast failure, a raw hex/px, or an axe violation — a gate blocks each. - Snapshots cover dark mode + RTL + the semantic-changing states, not just the happy path. - Manual a11y checklist signed off for the release.
Audit a UI or design against WCAG 2.2 AA/AAA and ARIA patterns, returning criterion-referenced findings with severity and specific fixes. Use when the user wants an accessibility check, contrast verification, keyboard/screen-reader review, or wants to confirm a component meets POUR.
Apply a visual direction — an archetype (high-end agency, editorial minimal, brutalist, soft-SaaS, dark-tech) or one of 138 named design systems (apple, linear-app, stripe, vercel, notion, material, shadcn, spotify, tesla…) — by resolving it into the token system. Use when the user wants a specific look/vibe/brand feel, or asks to make a design feel premium/expensive/non-generic.
Generate a complete, accessible brand design system from a brief — primitive → semantic → component DTCG tokens (color, type, spacing, radius, shadow, motion), light + dark, plus a single theme.css — verified for WCAG. Use when the user wants a from-scratch brand/design foundation, a new palette + type system, or a themeable token kit for a product.
Generate production-ready, accessible, token-driven component code for ANY framework — React+Tailwind, Next.js, SwiftUI, Vue, Svelte, Angular, Solid, Web Components/Lit, React Native, Flutter, Jetpack Compose, vanilla CSS, or CSS-in-JS. Use when the user wants working UI code for a component or screen in a specific stack.
Design a UI component spec to the house quality bar — anatomy, variants, sizes, the 8 states, token mapping, and accessibility. Use when the user wants to design or document a component (button, input, tabs, toast, combobox, date picker, modal, etc.) at the spec level before or alongside code. For generating framework code, use design-code.
Review or audit a design/UI across 6 weighted dimensions with Nielsen's 10 heuristics and a prioritized findings table. Use when the user wants a design critique, quality score, heuristic evaluation, or audit of an existing screen, page, or product before/after build.
Generate, extend, or audit design tokens in DTCG format with the 3-tier architecture (primitive → semantic → component). Use when the user wants a color palette, type scale, spacing/shadow/radius/motion tokens, multi-brand theming, or wants to validate token files. Covers colors, typography, spacing, shadows, borders, breakpoints, motion, gradients, opacity, blur, sizing, states, theming.
Keep Figma and code in sync — map the 3-tier DTCG tokens to Figma Variables (collections + modes), sync in either direction, use the Figma MCP when connected, and verify component parity (variants/states). Use when the user wants to push tokens/components to Figma, pull a design into code, set up token↔Variable sync, or check design-code drift.
