a11y-audit

该技能依据 WCAG 2.2 与 ARIA 模式审查已渲染 HTML 或 UI 设计，检查键盘、焦点、名称/角色/状态、对比度、目标尺寸和减少动态效果，并输出带 WCAG 准则、P0/P1/P2 严重级别和具体修复建议的发现表。它要求读取配套 kit 文档并运行 Node/Python 测量脚本，未附带这些文件时会提示安装并停止。

description
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.

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_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.

Evaluate against WCAG 2.2 and the project's ARIA patterns.

Steps

  1. Read ${CLAUDE_SKILL_DIR}/../../../accessibility/wcag-checklist.md (POUR-organized, P0/P1/P2) and ${CLAUDE_SKILL_DIR}/../../../accessibility/aria-patterns.md.
  2. 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.
  3. Verify WCAG 2.2 additions: Focus Not Obscured (2.4.11), Target Size (2.5.8), Accessible Authentication (3.3.8).
  4. 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) AND node ${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 ${CLAUDE_SKILL_DIR}/../../../scripts/contrast.py "<fg>" "<bg>". Never state a ratio you did not measure.
  5. Check reduced-motion handling (${CLAUDE_SKILL_DIR}/../../../taste/motion-choreography.md).

Output

A findings table: WCAG criterion (e.g. 1.4.3) · severity (P0/P1/P2) · what fails · specific fix. Confirm passes explicitly. Accessibility may never be traded for aesthetics.
