Skill: Accessibility Audit
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_MISSINGOnKIT_MISSINGonly the skill folders were installed, which is whatnpx skills adddoes. Say so plainly, point the user atnpx ux-ui-agent-skills initor the plugin install, and stop. Do not guess the contents of a file you could not open.
Evaluate against WCAG 2.2 and the project's ARIA patterns.
Steps
- Read
${CLAUDE_SKILL_DIR}/../../../accessibility/wcag-checklist.md(POUR-organized, P0/P1/P2) and${CLAUDE_SKILL_DIR}/../../../accessibility/aria-patterns.md. - Check the mandatory P0 set per component: keyboard navigable, focus visible (≥3:1), screen-reader name/role/state, contrast (4.5:1 text / 3:1 UI), target size ≥24×24, no color-only signaling.
- Verify WCAG 2.2 additions: Focus Not Obscured (2.4.11), Target Size (2.5.8), Accessible Authentication (3.3.8).
- Contrast — measure, don't eyeball. For rendered HTML, RUN the real-render gates and report their actual output (CLAUDE.md → Verification Protocol):
node ${CLAUDE_SKILL_DIR}/../../../scripts/measure_render.mjs <file> [--dark](every text element) ANDnode ${CLAUDE_SKILL_DIR}/../../../scripts/verify_states.mjs <file> [--dark](every interactive element in default/hover/focus — catches hover-state failures). For loose color pairs,python3 ${CLAUDE_SKILL_DIR}/../../../scripts/contrast.py "<fg>" "<bg>". Never state a ratio you did not measure. - Check reduced-motion handling (
${CLAUDE_SKILL_DIR}/../../../taste/motion-choreography.md).
