Skill: Design QA

Step 0: is the kit here? This skill reads files from the kit. Check once: ls ${CLAUDE_SKILL_DIR}/../../../tokens >/dev/null 2>&1 && echo KIT_OK || echo KIT_MISSING On KIT_MISSING only the skill folders were installed, which is what npx skills add does. Say so plainly, point the user at npx ux-ui-agent-skills init or the plugin install, and stop. Do not guess the contents of a file you could not open.

Stand up the automated + manual gates that stop quality from regressing.

Steps

1. Read ${CLAUDE_SKILL_DIR}/../../../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 ${CLAUDE_SKILL_DIR}/../../../scripts/validate_tokens.py, python3 ${CLAUDE_SKILL_DIR}/../../../scripts/validate_contrast.py (batch WCAG over the token pairs), and python3 ${CLAUDE_SKILL_DIR}/../../../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 ${CLAUDE_SKILL_DIR}/../../../scripts/gate.mjs 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; ${CLAUDE_SKILL_DIR}/../../../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.
