What it does
The skill first checks that the surrounding kit, including its `tokens` folder, is installed. If only the skill folders are present, it says so, points you to `npx ux-ui-agent-skills init` or the plugin install, and stops rather than guessing at files it cannot open. It then reads the kit's WCAG checklist, organized by the POUR principles with P0, P1 and P2 priorities, and its ARIA patterns.
Each component gets the mandatory P0 checks: keyboard navigation, visible focus, screen-reader name, role and state, contrast of 4.5:1 for text and 3:1 for UI, a target size of at least 24×24 and no color-only signaling. It also covers the WCAG 2.2 additions Focus Not Obscured, Target Size and Accessible Authentication, and reduced-motion handling. Contrast is measured, not estimated, by running the kit's render and state scripts. The output is a findings table with passes confirmed explicitly.
When your agent uses it
- Checking a component or page for WCAG 2.2 conformance
- Verifying color contrast and focus states on rendered HTML
- Reviewing keyboard and screen-reader behavior of a UI
Example prompts
- “Audit the checkout form in ./src/checkout.html against WCAG 2.2 AA.”
- “Measure the contrast of every text element in our dark theme.”
- “Confirm that the modal component meets the POUR principles and list fixes.”
Requirements
- The ux-ui-agent-skills kit installed, not only the skill folders
- Node.js and Python 3 to run the contrast and render scripts
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Read ${CLAUDE_SKILL_DIR}/../../../accessibility/wcag-checklist.md (POUR-organized, P0/P1/P2) and…
- Check the mandatory P0 set per component: keyboard navigable, focus visible (≥3:1), screen-reader name/role/state, contrast (4.5:1 text /…
- Verify WCAG 2.2 additions: Focus Not Obscured (2.4.11), Target Size (2.5.8), Accessible Authentication (3.3.8).
- Contrast — measure, don't eyeball. For rendered HTML, RUN the real-render gates and report their actual output (CLAUDE.md → Verification…
- Check reduced-motion handling (${CLAUDE_SKILL_DIR}/../../../taste/motion-choreography.md).
What it can do on your machine
Read from SKILL.md and the folder at commit 14f8d44. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npxnodepython3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Accessibility Audit loads about 542 tokens when it runs. Until then it costs about 74 tokens; SKILL.md has 212 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- 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_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).
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.
